Abstract
Proscriptive planning exercises are critical to and generally accepted as integral to health planning at varying scales.These require specific instruments designed to predict future actions on the basis of present knowledge. At the macro-level of health economics, for example, a number of future-oriented Quality of Life Instruments (QL) are commonly
employed. At the level of individual decision making, on the other hand, Advance Directives (AD’s) are advanced as ameans by which healthy individuals can assure their wishes will be carried out if at some future point they areincapacitated. As proscriptive tools, both instrument classes appear to share an axiomatic set whose individual partshave not been rigorously considered. This paper attempts to first identify and then consider a set of five axioms
underlying future oriented health planning instruments. These axioms are then critiqued using data from a pre-testsurvey designed specifically to address their assumptions. Results appear to challenge the validity of the axiomsunderlying the proscriptive planning instruments. # 2001 Elsevier Science Ltd. All rights reserved.

In North America generally, and especially in theUnited States, planning in advance of chronic illness orincapacity has become an increasingly accepted practice
for both health planners and for individuals. In healtheconomics, for example, cost-utility analysis presents amethod by which the relative cost of specific medical
interventions can be compared in terms of the healthstatus they are expected to produce (Freyback &Lawrence, 1997). More generally, individuals are urgedwhile healthy to set down ‘‘advance directives’’ (ADs) }
living wills, durable powers of attorney for health care,etc. (Post, Blustein & Dubler, 1999) } that will guide
and perhaps limit their treatment in the event of aserious health care emergency.Significant but largely distinct literatures have
grown around both streams of prospective instruments.In the arena of utilitarian health planning, this isfocused upon methodological and conceptual considera-
tion of a variety of future-oriented instruments.1
These include, in a partial listing: Quality AdjustedLife Years (QALYs) (Cohen, 1996); disability-adjustedlife-years (DALYs), a ‘‘special kind’’ of QALY
(Tsuchiya, 1998, p. 268), and Healthy Life Years(HeaLYs) (Hyder, Rotlant & Morrow, 1998). Ingeneral, these instruments calculate for a given
procedure the average number of additional life yearspotentially gained through a specific interventionmultiplied by a judgment of the quality of life in each
of those years (McDowell & Newell, 1996). All seek tomeasure the ‘‘burden of disease’’ in a manner thatensures ‘‘that resource allocation choices lead to the
most health for the money’’ (Hyder, Rotllant &Morrow, 1996, 1998).Healthy people are asked to imagine that ‘‘they are
suffering from a chronic condition for which the
symptoms, functional limitations, and a pain are

described. They are then asked to image that. . .they areoffered an operation that, if successful, would result in
complete recovery’’ (McDowell & Newell, 1996, 23–4).The operation carries, however, a risk of death. Therater is thus asked how great a risk of mortality they
would tolerate to avoid remaining in the condition firstdescribed. With variations for questions and context,persons are thus asked to define the degree of risk theywould accept to achieve a ‘‘healthy’’ as opposed to a
physically restricted life. Implicitly, the process assumesindividuals have the background to judge both the limitsof specific conditions and what their reactions to them
might be.Similarly, in the future-oriented class of AD instru-
ments, individuals are asked to define while healthy the
degree of disability they would be willing to tolerate inextremes. The intent is to provide advance informationto ensure a person’s wishes are fulfilled when and if that
person becomes incapable of making an informeddecision. At what stage of incapacity or restrictionwould life become insupportable to the potential, futurepatient? Would they accept ventilator assistance in
breathing for example? Would they wish to live in amore or less paralyzed (paraplegic, quadriplegic, or‘‘locked-in’’) state? Employed as a means of assuring
patient autonomy in cases of complex medical decision-making, the implicit assumption is, again, that a personhas the knowledge and awareness to judge what he or
she would choose in a medically complex situationinvolving short and potentially long-term physical orcognitive changes.Another type of prospective AD grants broad
authority to an agent who is assigned a decision-making proxy, should the issuer be incapacitated.Here the assumption is that, ‘‘if the patient had
issued an advance directive while capacitated,that directive should guide treatment decisions for her[or him] when she [or he] becomes incapacitated’’
(Blustein, 1999, p. 20). This class of directives thusattempts to represent by proxy a healthy individual’sjudgments on the acceptable quality of a future,
restricted life, following upon specific interventions(respiratory ventilation, for example). In this case, theassumption is that the designated decision maker will (a)act as the patient’s agent in a manner he or she would
approve, and (b) that the patient could accuratelypredict his or her actions in a situation of medicaldistress.
Despite the AD’s importance as a guarantor ofpatient autonomy, its utility presupposes a person’sfuture-oriented preferences will remain constant over
time. Recent studies have shown, however, this is notalways the case. Persons who have completed ADs oftenchange their views about treatment and care over the
course of their illness. In one recent study of AIDSpatients, for example, about one-fourth who had
completed ADs changed their minds about life-sustain-ing treatment over a 4-month period (Weissman, Haas,
Fowler et al., 1999). Of participants who initially saidthey would want cardiac resuscitation, 23% laterdecided to forego it. Conversely, 34% who initially said
they would decline this care later said they wouldaccept it.Nor do ADs necessarily serve as adequate guides for
surrogate decision-makers. Some have blamed this on a
lack of specificity (Fisher et al., 1997). While they mayprovide general directives } treat everything, forexample, or give only palliative care } these are often
insufficient to guide specific decisions in complexmedical situations. Additionally, family members whoact as surrogates may find it difficult to implement
directives that might shorten a person’s life and may beconfused by the often fine judgments required in medicaldecision-making in a complex context (Teno et al.,
1998). This is especially true when a patient’s cleardirectives, issued in health, are changed by that personover the course of an illness (for an example, see Koch,1990, 113–115).
The limits of ADs as useful, predictive instrumentsraise fundamental questions about proscriptiveinstruments generally. Despite the real differences that
attend both quality of life instruments and advancedirectives, they are aggregated here because bothshare a prospective methodology in which persons in
relatively good health are asked to predict how theywould act in extremes. Underlying both is a funda-mental question: Can we expect accurate judgmentsabout the judgments healthy individuals make when
asked to contemplate scenarios involving chronicphysical limits?
Quality of Life (QL) axioms
Underlying both classes of prospective instrumentslies a series of assumptions whose validity has notbeen examined. Together they represent a set of axioms,
untested, self-evident assumptions underlying aparadigm or theory that are assumed a priori to betrue (for an example of their importance in medicalethics see, Koch, 1998c). Indeed, it is precisely
because their validity appears self-evident that axiomsare rarely subject to rigorous critique. There appear tobe five central axioms underlying prospective health
planning instruments generally. They can be statedsimply:
Axiom 1. A person without a chronic physical deficitcan accurately compare healthy and restricted states.
Axiom 1a. (Corollary) Healthy persons have sufficient
knowledge and experience to make judgments about life
T. Koch / Social Science and Medicine 52 (2001) 453–465454
quality and satisfaction in the context of physical limitor disability.
Axiom 2. A healthy person can accurately predict whathe or she would want in extremes.
Axiom 3. Individuals have a core personality whoseperspective and judgments are constant whatever thephysical or social context.
Axiom 4. In public and personal health planning what isimportant is solely the degree to which an individual’s
physical condition deviates negatively from the norm.
Axiom 5. The discrete individual is always the sole and
best judge of appropriate treatment or non-treatment atany moment.
Axiom review
Axiom 1 assumes a healthy person can intelligentlycompare two health states and choose between them.This presupposes (1a.) he or she is sufficiently
knowledgeable about the potential of physically re-stricted lives to be able to accurately weigh thosepossible, future states in an intelligent fashion. If
the rater is generally ignorant in this area he or shewill have no solid basis from which the effects of limitedphysical states can be judged. This knowledge can be
experiential } based on personal association withthose whose physical state is restricted } or referredthrough general information sources (newspapers, radiostories, television documentaries, etc.). Similarly, axiom
2 assumes not only that a person is knowledgeable butalso that he or she can use that knowledge to accuratelypredict his or her judgments in the event of a physically
limiting condition. Even if one is knowledgeable, willthat knowledge be an effective guide to personal choice?What one thinks he or she would do in a future state
may differ markedly from what one in fact does,eventually, in that state.Axiom 3 offers a psychological model of constancy
critical to all assumptions about the efficacy of futurejudgments by healthy persons. Were the constancy of acore personality to be denied, any prospective decisionwould be that of a ‘‘past person’’ and thus unsuitable as
a basis for decision-making in extremes. The assumptionof ‘‘continuous personhood’’ irrespective of physicalcontext has been challenged most notably by Parfit, who
argues a complex interaction between a person’s historyand the degree to which that person’s personality maychange as a result of life events (Parfit, 1973, 1984). This
position and its relation to ADs were recently discussedby Rich (1997).
The fourth axiom, sometimes called the ‘‘medicalmodel,’’ uses ‘‘the pathogenesis and natural history of
disease as the conceptual framework for assessingmorbidity and mortality and for interpreting theeffects of various interventions’’ (Hyder, Rotllant &
Morrow, 1998). Reliance on a solely medical modelhas been critiqued both by those working withpatients facing chronic physical limitations (Young,Marshall & Anderson, 1994), and more generally, by
those advancing a broadly communitarian perspective(Koch, 1994; Kuczewski, 1999). It is held in particularcontempt by writers advancing a ‘‘disabilities
perspective’’ who argue, with Chamie (1995)that physical differences are not illnesses and shouldnot be treated as such. That this axiom underlies the
prescriptive health instrument’s calculation of a‘‘burden’’ of ‘‘lost’’ healthy life years is seen asparticularly odious by these critics (Chamie, 1995;
Pfeiffer, 1998, 505). From the perspective of peopleliving with physical differences, the medical modelresults in what some insist is a eugenic perspective thatmust be resisted.
A general counter-argument is that individual livesand life-choices occur within the context of a familial,and secondarily, a social dynamic that influences
individual choices (Hardwig, 1990). To the extentlife quality results from social and familial support,purely physical criteria will be inadequate. This perspec-
tive remains central to prospective health planninginstruments, and more specifically, to the generaldisability literature. Thus as recently as 1998, authorsdescribed the ‘‘disability paradox’’ as the reportage of
positive life quality by people with chronically limitingphysical deficits (Albrecht & Devlieger, 1998). Theparadox only exists, however, if one assumes that
diminished life quality and satisfaction necessarily resultfrom physical difference, and that the only significantcriteria to consider are those in the medical model
(Koch, 2000a). Thus this axiom, while sometimesdisputed, retains credibility, especially in the field ofdisability studies.
Axiom 5 reflects society’s belief in patient autonomy,and more generally, in individual self-determination. Itis based upon a central principle of modern bioethicsthat assumes the individual is the appropriate locus for
medical choices in cases of physical limit (Beauchamp &Childress, 1994). And yet, some have argued that ‘‘TheKantian self leaves out too much of what it is to be
human’’ (Nelson, H.L. 1995). To the extent personsliving with physical restrictions do so within a familialcontext, the role of the family } as participants and
potential decision makers } should not be discounted(Koch, 1994; Nelson, J.K. 1995; Nelson, J.L., 1992).And because some people may make ‘‘individual’’
decisions based on concerns for relatives who care forthem (caregiver burden, care costs, etc.), those decisions
T. Koch / Social Science and Medicine 52 (2001) 453–465 455
may reflect social and familial concerns rather thansolely personalized, individualistic perspectives.
Methods and testing
Viewed in this manner, the axioms underlying
prospective health instruments present a set of assump-tions that can be tested in various ways. Axiom 1, forexample, could be examined by asking healthy personscompleting prospective health instruments about their
experience with and knowledge of disabilities. Toexamine as many of these axioms as possible, however,a different approach was chosen. A survey was designed
to elicit the perspectives of persons now living withphysical limits. Questions sought first to uncover theirviews prior to diagnosis or injury and the knowledge
base underlying those views. Secondly, the survey wasdesigned to elicit current perspectives of those persons ina manner that allowed changes over time to beconsidered. Simply, a retrospective survey of persons
with disability was designed to examine the axiomsunderlying prospective tests in which healthy people areasked to judge physically limited states.
In the survey’s design and its eventual administration,assistance was sought from members of both generaldisability and disease-specific support and advocacy
groups. These included: the ALS Society of BritishColumbia, the ALS Society of Victoria (BC), the BCCoalition of Persons with Disabilities (BCCPD), and
members of an independent living coalition on Vancou-ver Island (IL). Members of the IL group reviewedseveral draft questionnaires, including one pre-tested byeight persons with Multiple Sclerosis, post-traumatic
brain injury, stroke or other chronic conditions. At thisstage, three areas of concern were identified: questionshad to be easily understood, presented in a manner
permitting an independent response by those withperceptual or motor deficits, and survey questions hadto be sensitive to issues of disability.
Crafting a survey that is both legible and accessible topeople with visual and/or motor limitations presentsvery specific challenges. In the pre-test phase, for
example, persons with visual impairments suggestedquestions be shortened to facilitate oral comprehension.Similarly, they suggested the elimination of follow-up
questions (i.e. If you responded ‘‘yes’’ to question 1.3. . .)requiring participants to remember one, two, or three
prior queries. Assuring ease of response by persons withgross and fine motor deficits was also a concern.At the suggestion of IL co-workers, participants were
given the option of either circling a word describing theirresponse or making a mark along a numbered intensityscale. The former permitted those with gross motordeficits to use a large pencil or magic marker to circle a
word or number reflecting their judgment. Responsesplaced on the scale by either method } circling ormarking on the line continuum } were measured
against the total length of a 10-cm. visual analog scale.The resulting figure was added for each question to acoding worksheet.
To facilitate completion by people with a variety ofphysical deficits, the questionnaire was offered invarying media, including audiocassette, on computer
disk, and in large (18-point) text format. The audioversion had a 3–5 sec blank space in which persons couldrespond orally to each question. The large text versionpermitted persons with limited visual acuity to either
read the questionnaire directly or use a computerizedscanner to bring it into their computer system. In theresulting study, two persons with quadriplegia requested
surveys on computer disk; five persons asked for largetext formats; one person used the audiocassette option.All others responded to a questionnaire presented in
standard, 12-point font.Space was provided for ‘‘Additional Comments’’ in
both tape and print versions for those wishing to addunstructured observations. A complaint by some pre-
test participants was that surveys typically offer littleopportunity for spontaneous responses. To ensure thatanyone wanting to discuss one or another question
would have the ability to do so, each question had acheck box saying, ‘‘I wish to talk about this’’.Researcher assistants were assigned to respond immedi-
ately to any request for discussion. Fig. 1 presents asample question with a check-mark response.The resulting survey is presented here as an Appendix.
All completed questionnaires were coded upon receiptfor both respondent affiliation and diagnosis (ALS,Multiple Sclerosis, etc.). To ensure confidentiality,names were excluded from scoring. At the end of the

questionnaire, participants were asked to include theirname and address if they wished to speak with
researchers or if they wished a copy of final reportsbased upon its analysis. Those interested in discussingthe survey or its issues were asked to indicate their
preferred medium of communication } fax, telephone,letter, or email } and the appropriate contact number.The final questionnaire was submitted for approval to
participating agencies and groups. They in turn dis-
tributed the survey to their members and collected allresponses. This ensured both the anonymity of partici-pants and general oversight by officials at the participat-
ing agencies. A cover letter accompanying all surveysbriefly described the researcher’s desire to learn frompotential respondents, the voluntary nature of the
participatory experience, and alternative methods ofresponse. Small financial donations were made to theBCCPD, the ALS Society of British Columbia, and the
IL group to acknowledge their support and defray anystaff and mailing costs incurred. Participants wereinformed of this donation.
Respondents
Because of the unusual nature of this project, a pre-test was initiated to determine its potential. Participantgroups were offered packets of questionnaires, and if
needed, additional packets were sent emphasizing one oranother medium (voice, large text, etc.). Participatingorganizations distributed 84 questionnaires to members
whose involvement was solicited through group news-letters and through personal requests. Thirty-fourcompleted questionnaires were returned over a periodof 3 months. While in other circumstances this might be
considered a low response rate it was, in this commu-nity, considered an endorsement. As a nurse and clientservices administrator explained, in apologizing for the
time it took for a questionnaire to be completed andreturned, ‘‘It’s not that people aren’t interested. It’s justthat the things of daily living take so much time and
energy. People want to finish it but the questionnairetakes time and energy to complete. And sometimes thereisn’t enough left over.’’ (McBride, 1999, Personal
communication).Approximately half of the respondents had been
diagnosed with neurological disorders } ALS and MS} while the rest had been diagnosed with a diverse
collection of physical disabilities resulting from injury orillness. Most suffered from gross motor deficits, mobilitydisorders, or both. Table 1 presents a general summary
of respondents by diagnosed condition. ‘‘Other’’ condi-tions included stroke, AIDS, fibromyalgia, cerebralpalsy, traumatic injury, Burger’s disease, and transverse
mylitus. Symptomatically, many people reported multi-ple limitations. For example, those with MS reported
physical weakness, pain, and in some cases, visuallimitations. The person with cerebral palsy also had
suffered a debilitating back injury that limited move-ments and caused continual pain. Respondents withALS reported a range of inhibiting gross and fine motor
deficits although none were, in this study, ventilatordependent.Emphasizing persons with neurological deficits as
respondents was a conscious decision. There is a general
assumption that persons with degenerative neurologicalconditions necessarily have a progressively unsatisfac-tory quality of life unworthy of continuance. Some
euthanasia advocates for example, have argued on thisbasis that physician-assisted suicide should be firstoffered to persons with ALS and MS (Mason &
Mulligan, 1996). Over 40% of the first 72 deathsattributed to Jack Kevorkian involved the euthanasiaof persons with these two conditions (Koch, 1998a).
Because persons with these conditions have been centralto the debate over quality of life and the efficacy ofeuthanasia (Koch, 1996, 1998b), their participation wasseen as critical to this study.
Demographically, 15 respondents were males, 16 werefemales. Three participants elected not to identifythemselves by gender. Of 34 respondents, 13 were
between the ages of 36 and 50 years; 14 were betweenthe ages of 51 and 65 years. Two identified themselves asbeing older than 65 while two others were younger than
35. Three respondents did not include their age. Sixreported they had lived with their illness or disability forbetween 1 and 5 years; ten said they had been living withtheir reported condition for between 5 and 10 years; and
16 said their condition had been extant for more than 10years. Two persons did not respond to this question.Nine of the respondents reported they are at present
working part or fulltime. 17 others reported they werenot working and seven said they were retired, working asvolunteers, or otherwise involved in non-remunerative
activities. One participant did not respond to thequestion. When asked about educational background,13 said they had graduated high school while nine said
they had at least some university training. Fourrespondents reported some graduate school experience,five technical school training in a technical school, andfive others said they had different types of post-
secondary training. A man with quadriplegia had flighttraining, for example. Several respondents marked morethan one educational category.

Results
Methodologically, the aim of this work was todetermine the survey form’s utility when applied to agroup of people with diverse physical differences and to
determine what questions if any needed to be revised fora planned, larger study. The small sample size (n=34)precluded any advanced statistical analysis, making itmore a sortie into a statistically rigorous critique than
that critique itself. Still, the data returned is sufficientlycompelling to permit discussion, and to argue fortentative if not definitive conclusions. In reviewing the
data returned, the arithmetic mean for each questionwas calculated based on participant marks or circlesalong the questionnaire’s answer line. A range of 95%
confidence based on the standard deviation of allresponses for each question was then calculated. Whereappropriate, raw data is reported based on respondents
circling or marking along the answer line.Participants first were asked to identify the number of
persons with disabilities or physical limitations they hadknown prior to their own diagnosis or injury (Table 1).
These included friends or relatives with similarly limitingdisabilities (question 1.1); acquaintances with mobilitydeficits (question 1.2); or other persons with voice,
vision, or other, overt physical differences (question 1.3).The intent was to determine what experience they hadwith disability before their injury or diagnosis.
Prior perception
Almost half said they had no previous experience withdisability on the basis of friends or relatives. Approxi-
mately 30% said they had one friend or relative withlimiting disabilities before their diagnosis and injurywhile 15 of 33 respondents said they had known one
such person with any of a range of disabilities (question1.2). Participants reported a slightly greater mean
number of acquaintances with mobility deficits outsidethe family and, not surprisingly, a yet larger number ofpeople with general (voice, vision) deficits. The arith-
metic mean was calculated for each question, using allresponses as measured along the test scale, and thus ismore precise than the raw summary data by categorypresented in the table (Table 2).
Participants then were asked if before their injury ordiagnosis they had considered the possibility they mightsomeday live with physical disabilities (question 1.4) and
whether they had taken their physical health andmobility for granted (question 1.5) (Table 3). Theassumption } not supported by the data returned }
was that those who had earlier been most intimatelyinvolved with persons with chronic limits would be lesslikely to take their own physical health for granted. That
is, if a person’s parent had a chronic condition requiringa child’s assistance that child would, as an adult, have agreater awareness of the possibility of physical limits.The majority of respondents } 27 of 32 answering this
question } said they never previously considered thepossibility they might someday have a physically limit-ing condition. On a scale of 0–10 with 10 representing
those who had carefully and consistently considered thepossibility of a physically limited life, the mean responsewas 0.98. Similarly, 24 of 32 respondents said they had
absolutely taken their health for granted while only tworespondents said they had never done so.These data may explain participant responses to
questions regarding ADs. While all respondents said
they knew what ADs are (n=33), only two said they hadcompleted a living will or AD prior to illness or injury(question 1.10). Most not only took their own health for
granted, but rarely considered the possibility that at

some date in the future their physical circumstancemight change. There was no reason, in short, to plan for
a context none expected to occur (Table 3).More interesting, perhaps, was their present uncer-
tainty about ADs (question 1.12). When asked if they
were to fill out an AD today if that directive would bedifferent from one they might have completed beforetheir diagnosis or injury, the response was equivocal. Ona scale of 0–10 (0 equals ‘‘no’’ and 10 equals
‘‘absolutely’’) the mean response was 4.52� 1.5. Simi-larly, persons were uncertain whether before diagnosisor injury they would have assumed themselves capable
of accepting their currently restricted lifestyle (question1.13). On a scale of 0–10 the mean response (n=32) was5.45 (5=‘‘perhaps’’)� 1.34.
To better understand their perception of physicaldifference, participants then were asked whether, priorto accident or disability, they had thought the lives of
people with disabilities were less full (question 1.6) orless valuable (question 1.7) than those of others insociety. Here the results were mixed (Table 4). Sixrespondents did not answer because, they said, they had
never considered the issue. While one third of allrespondents answered negatively, two thirds indicatedthey had to some degree assumed a physically restricted
life by definition would be less full. Similarly, an equalnumber also insisted they had not believed (beforediagnosis or injury) a physically restricted life was less
valuable. A distinction was thus made retrospectivelybetween a ‘‘full’’ life and what makes one or another lifemore or less valuable in society (Table 4).
Current perspectives
Most participants were uncertain whether, prior toaccident or disability, they would have been able toaccept their current, physically restricted life and its
attendant life style. On a scale of 0–10, the meanresponse to question 1.9 } ‘‘Before your diagnosis orinjury would you have been able to easily handle your
current life style? } was 4.9 (‘‘perhaps’’)� 1.5. Tworespondents who did not answer the question said ‘‘Inever thought about it’’. In a second, similar question
(question 1.13) } ‘‘Before your diagnosis or injury,would you have been able to accept your life today?’’ }
the mean response was an equivocal 5.45(� 1.34).
This prior uncertainty makes all the more remarkablethe participants’ strong sense of affirmation regarding
their current, physically restricted lives. When asked(question 2.5) ‘‘Do you consider your life today worthliving?’’ the mean response was a very positive
9.5� 0.387 (n=32). When asked (question 2.3) if ‘‘thereare positive aspects to your life today you would nothave previously anticipated’’, the mean response was astrongly positive 7.24� 1.31. When asked (question 2.7)
to indicate those areas in which life quality wasunexpectedly richer, 13 respondents marked social and13 marked familial areas of relationship. Seven partici-
pants noted an unexpected boon in spiritual areas andseven in areas of their professional affairs. Within thisset } participants were free to check one or more
category } four noted other areas of unexpectedsatisfaction not categorized by the survey (an increasedsense of maturity, of self-awareness, relations to profes-
sional caregivers, etc.). Respondents indicating areas ofpositive life experience including participants who inresponse to earlier questions (question 2.1–2.4) indicatedthat, compared with their lives prior to diagnosis or
injury, they now spent the same or less time with family,friends, and on spiritual matters. The conclusion drawnwas that whatever the quantity of time spent in these
areas } more, less, or unchanged } the quality of theexperience in each area was richer and more meaningful.This agrees with the findings of Tsevat and Sherman
(1999) whose study of HIV-infected persons found astrongly positive life quality, one that was more spiritualand whose daily activities were richer. It similarlyenforces the findings of Young and McNicoll (1998)
whose respondents in a study of the perceived lifequality of persons with ALS (motor neuron disease)reported stronger interpersonal ties and a richer spiritual
life than before diagnosis.
Suicidal impulses
The assumption that persons with chronic, andespecially chronic progressive disorders, experience a
desire for termination has been considered explicitly andimplicitly in a variety of literatures (Kemp, 1993; Koch,1996, 1998a; Miller, 1993). And certainly, some persons
with chronic and chronic progressive disabilities doconsider termination. To consider the issue of suicide asa response to chronic physical difference, survey

respondents were asked first whether they had consid-ered suicide before their diagnosis or injury (question
2.8) and then whether they had considered it afterwards(question 2.10). Finally, they were asked whether theywould consider suicide if their condition were to
deteriorate in the future (question 2.9). The assumptionwas that self-termination would be an option consideredfar more frequently post-injury or diagnosis than it hadbeen in a state of normalcy. Further assumed was that
suicide would be a more likely consideration as theseverity of physical restrictions increased.These assumptions were not supported. The mean
response to the first question (question 2.8) was1.83� 0.64 with only two people responding with ascore of 5 or more (occasionally to frequently). A mean
response of 2.38� 0.85 to the second question (question2.10) was only marginally higher. In a review ofindividual responses, as many participants reported
diminished suicidal impulses after diagnosis or injuryas reported greater frequency of ideation. When askedwhether they might consider suicide if their conditionwere to deteriorate in the future, the mean response was
3.9� 1.398. There seemed to be no correlation at thislevel between either an individual’s level of disability orthe nature of his or her condition. The sample was too
small, however, for this issue to be considered rigor-ously.
Social support
A problem arose with questions involving the degree
to which additional social support would improverespondent life quality. Only six said they needed moredaily assistance (question 3.8), marking responses at7.8–10 on the ten-point scale. Seven respondents who
responded negatively to this question, however, com-mented that their caregivers required help or that theyand their caregivers would require help at a future point.
Similarly, when asked specifically about the need foradditional home care, the mean response was 6.02 on ascale of 1–10� 2.19. Again, several who responded
negatively added ‘‘not now,’’ ‘‘not yet,’’ or ‘‘for mycaregiver, perhaps.’’ When asked about specific technol-ogies which might improve their lives, 15 noted that
better telecommunication equipment would materiallyassist their lives; six noted a need for better citytransportation for persons with deficits; and eightindicated a need for both specialized personal vehicles
and for in-home devices. Again, some said they didn’tneed additional technologies ‘‘now,’’ or ‘‘yet’’.Clearly, these questions were not sufficiently specific
to time frame or factor. This section of the survey is inthe process of being rewritten to take into account bothpresent and future time frames as well as the role of
caregivers. In the next iteration, participants will beasked first about the telecommunication, mobility, and
in-home devices they have at present. They will then beasked about their and their caregivers’ current needs,
and separately, about potential future needs.
Study limits
As one peer reviewer noted of an earlier draft, this
approach raises a range of interpretive and conceptualissues that will require careful consideration. Somemight question whether the validity of the memories andperspectives of these respondents should be credited. Do
they remember correctly or not? Are they reportingaccurately? Simply, some may dismiss this work basedon the assumption that the memories of these respon-
dents are unreliable, and perhaps self-servicing. To thisit may be answered that if one accepts the proscriptivejudgments of healthy individuals about how they might
act in one or another health state, the views of peoplewho are living in that state should be at least equallyvalued.Even accepting the validity of these responses, some
might question their relation to the axiom set, and atanother level, their relation to prospective healthplanning instruments generally. This work thus can be
questioned at the level of participant response and at theconceptual level in which the axioms and their relevanceare asserted. Pre-tests are instructive and evocative but
never conclusive. This is especially true when they areinstituted to consider existing assumptions in a new way.Unfortunately, issues of interpretation and application
must await other, hopefully larger surveys in which thesefindings are supported, expanded, or revealed aseccentric.To the extent the perspectives of these respondents are
accepted, how are they to be weighed in social andpolicy debates in health care? And, of course, to whatextent do we accept the axiom set as correct and
relevant? With the work of others who have presentedsuggestive data from small-scale samples (Tsevat, Sher-man & Elwee, 1999; Young & McNicoll, 1998; Young,
Marshall & Anderson, 1994), the data returned by thiswork appears to challenge central assumptions ofcurrent North American health care planning, and
secondarily, bioethics. Further, it appears to supportthe perspective of disability proponents who insist thatphysical difference be perceived not as a solely medicalcondition whose effect can be predicted, but as a
complex social and interpersonal reality.The data presented suffer from the smallness of the
sample and its perhaps imaginative but still atypical
focus upon the memories and current perspectives ofpeople living with physical differences. And yet, theresults of this study confirm and extend those of others
whose similarly small samples have explored the positivelife quality reported by those with physical differences
T. Koch / Social Science and Medicine 52 (2001) 453–465460
resulting from injury or illness (Tsevat, Sherman &Elwee, 1999; Young & McNicoll, 1998). With the work
of these and others advocating a more complex view ofthe life of persons with physical differences (for a reviewsee Koch, 2000b), the foundation has been laid for an
expansion of this research in studies involving greaternumbers of participants from these and other commu-nities. As one peer reviewer noted, consideration ofaxioms 1 and 2 would benefit from detailed testing
among physically normal populations. What knowledgedo people completing QALYs, HeaLYs, and DALYshave about the health states they are asked to weigh?
How knowledgeable are physically mundane people whofill out ADs arguing against continuation of care in thisor that physical state?
Finally, the relevance of the axioms themselves mightbe thoughtfully considered in relation to the greater,international literature on prospective health planning.
Different perspectives may be returned if the axioms ofprospective health planning are considered through thelens of European and Asian writings in this area. Almostcertainly, study participants from those cultures will
have different historical knowledge bases. Experiences ofcurrent disability may differ markedly as well, especiallyin those European communities offering greater support
to people with physical limits.
Discussion
The results returned in this pre-test seemed, at the
least, suggestive; offering a potentially valuable insightinto the axiom set underlying prospective healthinstruments. The first two axioms, for example, areclearly challenged by this data. Prior to diagnosis or
injury, persons living with disabilities had little experi-ence with or interest in the realities of a physicallydistinguished health status. They knew few persons
living with disabilities and gave little thought to thepossibility of a ‘‘disabled’’ or ‘‘limited’’ potential in theirown lives. To the extent they considered these issues, the
average respondent assumed people with physicaldifferences might live a less full if not an inherently lessvaluable life. Even among those who grew up with
physically challenged relatives there was little expecta-tion that they, too, might someday face a life withsimilar chronic deficits.Simply, these persons reported no basis for comparing
healthy and diseased states. Nor could any havepredicted accurately the choices they would make inthe face of a chronically limiting physical condition.
While none were certain that their earlier selves couldhave coped easily with their current life status, mostreported positive life quality aspects that were not
anticipated prior to injury or illness. While some of thesebenefits were personal } a sense of increased spiri-
tuality, for example } many reflected a deeper sense ofsocial and familial relation. Clearly, this challenges the
fourth axiom. Life quality is dependent on social andfamilial relations rather than solely on the basis ofphysical ability or disability. While this result was
anticipated by previous studies (Young & McNicoll,1998), those conclusions regarding the process ofadaptation are confirmed and extended by the currentstudy.
The assumption of personal autonomy as the drivingaxiom of medical-decision making is also challenged bythese responses. Participants described current lives
whose life quality is intimately bound up in theirconcern for and dependence on caregivers. This wasmade clear by responses to questions 2.6 and 2.7, for
example. In addition, comments added to the lastquestion section regarding home care and technologicassistance } ‘‘I don’t [need anything] but my [caregiver]
wife does,’’ for example } suggest a sense of relationbetween caregiver and care receiver that deserves furtherexploration. These results suggest, for example, thetestable hypothesis that persons living with chronic and
limiting conditions now make apparently independentlife decisions on the basis of caregiver needs. Even if thisis true it would not necessarily follow, however, that
those persons would want to cede at least some overtdecision-making responsibility to those caregivers. Thispossibility, once identified, can easily be explored,
however.While it is impossible to consider definitively issues
raised by personhood constructs (axiom 3), some ofthese responses do suggest directions for further
research. To the extent that people consistently rejectedsuicide before and after diagnosis or injury suggests aconstancy irrespective of physical condition. Were there
no continuous personhood, one might expect this tochange dramatically as the individual’s physical state isaltered. And yet, respondents clearly believe they have
changed and grown while adapting to their currentphysical conditions. They have found additional andunanticipated benefits in social relations, familial
associations, and spiritual considerations.A working assumption might be that while most
individuals retain a core of individualized, historicallygrounded perceptions and values that are relatively
constant, the ‘‘historical self’’ that does not precludecritical changes and adaptations. These may occurin response to both changes in physical condition }
and thus self-image } and the greater social contextin which those changes occur. The historical self,whose values are constant, serves as a guide but
not necessarily a restriction when a life’s context isaltered. Its assumptions and values may be radicallyaltered by circumstance. This is in accord with
qualitative studies of disability in which individuals saya part of them died so that the rest of their personality
T. Koch / Social Science and Medicine 52 (2001) 453–465 461
might live in a physically restricted state (Koch, 1998b,chap. 3).
This explains, perhaps, the rationale behind thefrequency with which persons who live with chronicprogressive conditions may alter an AD written in
health. It similarly explains why some people withchronic and debilitating conditions } the humanimmunodeficiency virus, for example } may reportboth an improved life quality and a reluctance to trade
off any life years for ‘‘perfect health’’ (Tsevat, Sherman& McElwee, 1999). The experience of disability forceschanges in perception and values depending on a
range of accommodations. These are based on thepresence or absence of social and familial supportas well as the specific nature of the physical restriction.
If support exists } in the home, work place, andthe greater community } people may decide tocontinue with a restricted life for far longer than
might have earlier been anticipated. If howeversupport is absent, and life becomes restricted, accom-modations will be limited and life quality diminishedas a result. The degree to which individual perception is
or is not influenced by these or other factors }
education, for example } remains a subject for furtherexploration.
Conclusion
Prospective health planning instruments axiomati-cally assume individuals can predict accurately thechoices they would make in the event of a physically
limiting condition. To do so, however, assumes aknowledge basis and familiarity with different states ofdisability } an awareness of one’s own potential as aperson-with-differences } that among study respon-
dents was extremely rare. Respondents had littleexperience with physical disability and little interest in
issues surrounding a physically challenged life prior toinjury or diagnosis. That most respondents currently
report a strong life quality, despite their moderate tosevere physical limitations, apparently speaks not to a‘‘disability paradox’’ (Albrecht & Devlieger, 1998), but
to a process of social and familial adaptation whosebenefits were clearly unanticipated by respondents priorto injury or diagnosis. Thus the axiomatic assumptionthat life quality is largely or wholly based on physical
deviations from the norm was not supported by thiswork.Clearly, the small size of the sample employed in this
survey requires that the work be repeated and expandedbefore any definitive determination can be maderegarding these axioms. Similarly, the set of axioms
identified here as critical to proscriptive instrumentsdemands rigorous review by scholars and ethicistsinterested in these issues. That said, the importance of
the data returned } and the challenge it presents tocurrent approaches in health care planning } isunequivocal. To the extent proscriptive instruments donot adequately measure the reality of life quality in the
context of physical difference, methods of medicalplanning and allocation will need to be broadlyreconsidered.
