    relationship: Infidelity type, gender, and

    commitment as factors related to distress andforgiveness

    AbstractThe overall aim of this study was to examine differences in responses to relationship infidelity when the infidelity

    involves a former romantic partner as opposed to a new rival. Participants indicated, for either sexual or

    emotional infidelity, whether they would be more upset if their partner were involved with a former partner or a

    new person, and whether they would be forgiving. Men and women saw the former partner as a greater threat

    when the infidelity was sexual. However, for emotional infidelity, only women selected the former partner more

    frequently. Ratings of the degree of distress and likelihood of forgiveness followed a similar pattern. For women,

    measures of relationship commitment were related to distress and forgiveness. For men, these measures were

    related to forgiveness only. The gender differences in distress may be related to differences between men and

    women in beliefs about the importance of commitment.

    Infidelity in a romantic relationship is a

    source of strong emotional reactions and a

    threat to the stability of the relationship

    (Buss, 2000). Any evidence, real or imagined,

    that one member of the relationship might

    be attracted to, or be involved with, a rival is

    likely to arouse distress in the romantic part-

    ner and threaten the continuation of the

    relationship. However, whereas distress islikely to be the initial response to any

    evidence of infidelity, forgiveness for the

    infidelity might eventually be granted. In

    committed relationships, partners are often

    willing to accommodate one another (Rusbult

    & Buunk, 1993; Rusbult, Martz, & Agnew,

    1998), so that despite the distress of the

    infidelity, forgiveness might be possible (Fine

    & Sacher, 1997), although the distress may be

    harder to manage in some cases of infidelity

    than in others (Shackelford, Buss, & Bennett,

    2002).The degree of distress or jealousy that

    results from potential infidelity, and the

    possibility of forgiveness, may be influenced

    by a variety of factors related to gender, the

    nature of the behaviors involved, and the

    qualities of the rival (Buss, 2000; Buunk &

    Dijkstra, 2000; DeSteno & Salovey, 1996).

    For example, women are more threatened

    by a physically attractive rival, while men

    fear more a rival who presents himself asdominant (Buss, Shackelford, Choe, Buunk,

    & Dijkstra, 2000; Dijkstra & Buunk, 1998).

    Moreover, recent research has provided

    some support for gender differences when

    This research was completed by the second author asan honors research thesis under the guidance of thefirst author. Both authors thank I. J.

    individuals are forced to choose which one

    among alternative forms of obvious infidel-

    ity would be more upsetting. Buss and col-

    leagues (Buss, Larsen, & Westen, 1996; Buss,

    Larsen, Westen, & Semmelroth, 1992; Buss

    et al., 1999; Buunk, Angleitner, Oubaid, &Buss, 1996) have reported consistent differ-

    ences between women and men in the distress

    anticipated when confronted by imagined

    sexual, as compared with emotional, infidel-

    ity. Men choose sexual infidelity as more

    distressing, while women choose emotional

    infidelity.

    In each of these instances, the original

    predictions have been guided by an evolu-

    tionary model, although alternative models

    have been suggested to explain the results.

    For example, on the basis of an evolution-

    ary model, men are expected to be more

    distressed by sexual infidelity because they

    are less certain of paternity. Women, on the

    other hand, should be more distressed by

    emotional infidelity, which signals a loss of

    commitment and a possible loss of the

    future resources and protection they seek

    from a mate. Others have suggested that

    these same gender differences could bethe result of learned social expectations

    (DeSteno & Salovey, 1996; Harris, 2000;

    Harris & Christenfeld, 1996), without

    necessarily requiring a role for evolved sex

    differences. Given the conflicting findings in

    this area, and the competing explanations

    for them, the overall aim of the present

    study was to further examine the roles of

    gender, rival type, infidelity type, and rela-

    tionship commitment in predicting distressand likelihood of forgiveness in response

    to imagined infidelity.

    Former Partners as Threats to Relationships

    One rival quality that is associated with

    jealousy, but for which an evolutionary per-

    spective should differ from expectations

    based on social beliefs, is a past relationship

    between ones partner and a rival. Ratherthan representing a fixed quality of the

    rival, a past relationship involves a transient

    condition associated with a rival. The

    potential salience of these past relationships

    is evident in reports of experienced and pro-

    voked jealousy. In a survey of college stu-

    dents, the two most commonly mentioned

    sources of jealousy involved associations

    with a previous partner (talking to or

    talking about a previous partner; Knox,Zusman, Mabon, & Shriver, 1999). Another

    survey found that many college students

    intentionally make references to former

    partners to evoke jealousy in current part-

    ners. In fact, talking about a prior relation-

    ship was rated as likely to cause a fight in

    the relationship by 28% of a sample (Sheets,

    Fredendall, & Claypool, 1997). Obviously,

    a former relationship is believed to be a

    potential threat to a current relationship.

    Why might a former partner be such a

    potent and recognized source of jealousy?

    On the basis of evolutionary processes, for-

    mer partners should be seen as minimal

    threats, because the current partners

    already have successfully out-competed

    them, proving their fitness advantage, to

    establish the existing relationship. If the

    competition for a mate is based on fitness

    advantages, the rival who has been

    defeated should become less of a threat.On the other hand, the common and appar-

    ently successful use of a former partner to

    arouse jealousy implies that these rivals are,

    in fact, seen as serious threats. A prediction

    based on learned social expectations would

    reflect the fact that individuals are often

    portrayed in narratives about relationships

    as returning to past lovers. The media are

    filled with stories of lovers being reunited

    after a separation, leading to a happyending. The implication of these socially

    constructed messages may be that the

    emotional connection with a former partner

    is a bond that remains even though the

    relationship has ended, eventually drawing

    partners back together again. If some emo-

    tional connection is assumed to persist,

    women, more so than men, may feel more

    threatened by past partners, given their

    greater concern about emotional infidelity.Because no study has directly compared a

    previous partner with a new rival, it

    remains to be shown that the prior partner

    is truly perceived as a greater threat to a

    306 A. Cann and T. R. Baucom

    3/14

    relationship or, as predicted by an evolu-

    tionary model, that the former partner is

    not perceived as a serious threat.

    The first aim in the current study was to

    directly test the differences, if any, in

    responses to former partners and new rivalsas threats to relationships. Social uses of

    former partners as a common means of

    arousing jealousy imply that these indivi-

    duals are seen as serious rivals, yet an evo-

    lutionary model predicts the opposite, that

    a new rival will be more of a threat since a

    fitness advantage over the new rival has not

    been established. One possible reason a for-

    mer partner might be a greater threat is

    because we have learned, through social

    messages, that emotional ties may not be

    completely broken even though a relation-

    ship ended. Given the demonstrated ten-

    dency to use former partners to arouse

    jealousy, we would predict that former part-

    ners would cause greater concern. In add-

    ition, because emotional ties are held to be

    more important to women than to men, we

    would expect women, more than men, to

    fear the former partner.

    Infidelity Type

    As indicated earlier, researchers have con-

    sistently found a gender difference in

    womens and mens reports of which type

    of infidelity (sexual or emotional) would be

    more distressing (Buss et al., 1992, 1996,

    1999; Buunk et al., 1996). Men choose sex-

    ual infidelity, and women choose emotional

    infidelity. However, the gender differencesin distress because of infidelity type appear

    consistently only when using a forced-

    choice comparison. Studies that have

    looked at separate ratings of the degree of

    distress each infidelity would cause, or the

    physiological indicators of arousal asso-

    ciated with each infidelity, have produced

    inconsistent results. Cann, Mangum, and

    Wells (2001) and Pietrzak, Laird, Stevens,

    and Thompson (2002) found the predictedgender differences in rated distress, while

    DeSteno, Bartlett, Braverman, and Salovey

    (2002) and Harris (2000) did not. Similarly,

    Buss et al. (1992) and Pietrzak et al. (2002)

    found physiological responses (heart rate

    and electrodermal activity) consistent with

    predictions, but Harris (2000) did not. It

    could be argued that when men and

    women are forced to choose, they choose

    what they believe they should choose, andso they choose differently. However, when

    each infidelity is considered separately,

    mens and womens responses may be

    based solely on their evaluation of the

    impact of the infidelity presented.

    The second aim in the current study was

    to further examine gender differences in the

    rating of the distress associated with sexual

    versus emotional infidelity. In past research,

    distress ratings for the two forms of infidel-

    ity have always been collected as a within-

    subject variable. In the current study, the

    two ratings are treated as a between-subject

    variable, to minimize the likelihood of

    social expectations about how one should

    respond to one type of infidelity or the like-

    lihood of the other altering the responses.

    Without the ability to compare the two

    types of infidelity, it is expected that gender

    differences will be minimal or entirely

    absent. Both types of infidelity are undesir-able, but sexual indiscretions should be

    more distressing than emotional indiscre-

    tions to men and women alike.

    Predicting Distress and Forgiveness

    Following Infidelity

    Recent research has found gender differ-

    ences in forgiveness following infidelity,

    depending on both the type of infidelityinvolved and the degree of distress reported.

    In a direct comparison of sexual versus

    emotional infidelity, both men and women

    found sexual infidelity more difficult to for-

    give, but compared to women, men more

    frequently selected sexual infidelity as

    harder to forgive (Shackelford et al., 2002).

    In a subsequent question in which partici-

    pants were asked to imagine that both

    sexual and emotional infidelity hadoccurred, women now more frequently

    selected emotional infidelity as the aspect

    of the dual infidelity that would be hardest

    to forgive. Because men find sexual

    Infidelity and forgiveness 307

  • 7/27/2019 Cann y Baucom (2004)

    4/14

    infidelity more distressing than emotional

    infidelity, these results are consistent with

    the idea that distress is negatively associated

    with the likelihood of forgiveness. The third

    aim in the current study was to examine the

    correspondence between distress ratingsand judgments of likely forgiveness. By col-

    lecting ratings of distress and likelihood

    of forgiveness, and by assessing infidelity

    type as a between-group factor, the results

    allow for a determination of the reliability

    and generality of the findings reported by

    Shackelford et al. (2002).

    The Role of Relationship Commitment

    Romantic relationships, like any relation-

    ships, require a certain degree of commit-

    ment to ensure their continuation. As

    commitment increases, the relationship

    becomes more stable, and the willingness to

    accommodate one another in the relation-

    ship increases (Rusbult & Buunk, 1993;

    Rusbult et al., 1998). One likely accommoda-

    tion in committed romantic relationships

    involves a willingness to forgive some trans-

    gressions. However, the degree of commit-ment also is likely to be related to the distress

    experienced if the relationship ends (Fine &

    Sacher, 1997). Thus, commitment should be

    an important factor in helping to understand

    both distress and forgiveness responses

    following infidelity.

    Indirect evidence that forgiveness will

    vary with commitment can be drawn from

    studies reporting that the decision to leave

    or stay in an abusive relationship canbe predicted from variables associated

    with commitment (Rusbult, & Martz,

    1995; Truman-Schram, Cann, Calhoun, &

    Van Wallendael, 2000). Although these

    decisions may not be based on forgiveness

    alone, results indicate that even after being

    seriously wronged in a relationship, higher

    commitment leads to a greater attempt

    to maintain the relationship. Two recent

    studies provide more direct support for theproposed relationship. McCullough et al.

    (1998) found a link using a relationship

    satisfaction/commitment composite, and

    Finkel, Rusbult, Kumashiro, and Hannon

    (2002) found consistent associations between

    commitment, as measured using a more

    specific measure of relationship commitment,

    and positive reactions, viewed as instances

    of forgiveness, following betrayal.

    The final aim in the current study was toexamine the associations among measures

    of relationship commitment and reactions

    to infidelity. Specifically, relationship com-

    mitment variables are used to predict mens

    and womens distress and forgiveness in

    response to the two types of infidelity. If

    differences in relationship commitment

    explain a significant portion of the variabil-

    ity in distress and forgiveness, beyond the

    impact of the infidelity type, the results

    would provide additional support for the

    proposal that learned social expectations

    are important in understanding mens and

    womens reactions to relationship infidelity.

    The predictions are that higher commitment

    will be associated with both greater distress

    and a higher likelihood of forgiveness, for

    both men and women.

    Method

    Participants

    Participants were students enrolled in intro-

    ductory psychology courses who volun-

    teered to fulfill a course requirement. The

    announcement soliciting volunteers indi-

    cated that participants had to be unmarried

    but currently involved in a committed

    romantic relationship. There were 71 men,

    with a mean age of 20years (SD 2.78),

    and 69 women, with a mean age of

    19.3 years (SD 2.18). The current roman-

    tic relationship had a mean length of

    17 months (SD 14.3), with a range from

    1 month to 72 months. The current relation-

    ship was reported to be sexual (Is this a

    sexual relationship?) by 81% of the sample

    (n 134). There were no gender differences

    on any of these variables.

    Materials

    Responses to the infidelity. After providing

    the demographic information described

    308 A. Cann and T. R. Baucom

  • 7/27/2019 Cann y Baucom (2004)

    5/14

    above, the second section of the survey

    varied depending upon the participants

    assigned condition. Participants responded

    to an imagined episode of either emotional

    infidelity or sexual infidelity. In all cases,

    they were told to imagine that the personthey were currently involved with had been

    unfaithful. One of the two phrases described

    below was used to specify the nature of the

    infidelity. For those in the sexual infidelity

    group, they were asked to: Imagine your

    partner having casual sexual intercourse

    without emotional involvement with. . .

    For those presented with emotional infidel-

    ity, they were asked to: Imagine your

    partner becoming emotionally involved

    without sexual intercourse with. . .

    Within

    each of these conditions, they were asked to

    indicate which of two rivals (a former part-

    ner or a new person) would upset them

    more. The following phrases were inserted

    at the end of the sentences describing the

    infidelity to represent the different rivals:

    . . . a former partner (someone your part-

    ner dated before) or . . . a new person

    (someone your partner recently met).

    After choosing which other person, theformer partner or the new person, would

    be more upsetting as a rival, the participants

    rated how distressing each possibility would

    be on a nine-point scale [slight distress (1) to

    extreme distress (9)]. Finally, they rated

    how likely they would be to forgive their

    partner for the infidelity with each rival,

    on a nine-point scale [definitely would

    not forgive (1) to definitely would for-

    give (9)]. Therefore, a participant waspresented with an episode of either sexual

    or emotional infidelity (a between-group

    manipulation), where the rival was a former

    partner or a new person (a within-group

    variable). This design provides for the

    desired direct comparison between the two

    rivals and for the assessment of distress

    when the two forms of infidelity are inde-

    pendently rated. For each of the three meas-

    ures (the forced choice as to which rival wasmore upsetting to imagine, the ratings of

    distress for each rival, and the ratings of

    forgiveness for each rival), the order of the

    options (former partner or a new person)

    was varied across participants. These very

    brief descriptions of the infidelity were pat-

    terned after those used in studies that had

    previously tested for forced-choice decisions

    (Buss et al., 1999; Cann et al., 2001). Although

    the descriptions lack detail, providing choicessimilar to those included in previous studies

    will allow for clearer comparisons across

    studies.

    Commitment measures. The next section of

    the survey was the Investment Model Scale

    (Rusbult et al., 1998). The scale provides

    separate measures for the four components

    of the Investment Model. There are 22

    items, with composite scores created for

    satisfaction (five items, e.g., I feel satisfiedwith our relationship.), investments (five

    items, e.g., I have put a great deal into

    our relationship that I would lose if the

    relationship were to end.), quality of alter-

    natives (five items, e.g., My alternatives to

    our relationship are close to ideal.), and

    commitment (seven items, e.g., I am com-

    mitted to maintaining my relationship with

    my partner.). Each item was rated on a

    nine-point scale [do not agree at all (0)to agree completely (8)]. The participants

    were instructed to respond to the items

    based on their current relationship.

    Procedure

    Participants were scheduled in small groups

    (310 per group). After reading the necessary

    informed-consent information, participants

    received the survey packet. Within a group,surveys containing the sexual infidelity and

    emotional infidelity scenarios were randomly

    distributed. When all participants at a ses-

    sion had completed the surveys, participants

    were debriefed, and any questions were

    answered. Sessions lasted about 30 min.

    Results

    Forced-choice responses to infidelity

    scenarios

    Overall, infidelity involving a former part-

    ner was selected as the more upsetting

    6/14

    event, but the extent of the preference did

    vary as a function of the type of infidelity

    (Table 1).1 The former partner was selected

    with a higher relative frequency when the

    infidelity involved was sexual (73%) ratherthan emotional (57%) [2(1, N 140)

    3.80, p 0.05]. However, when the gender

    of the participant was considered, men and

    women differed in their rate of choosing the

    former partner when the infidelity was emo-

    tional (women 70%, compared to men 46%)

    [2(1, N 70) 4.02, p 0.045], but with sex-

    ual infidelity, the frequencies were equivalent

    (women 72%, men 74%) [2(1, N 70)

    0.02, p 0.902].

    Ratings of distress

    The distress ratings (1 slight, 9 extreme)

    were evaluated in a 2 (gender) 2 (infidelity

    type) 2 (rival) analysis of variance, with

    repeated measures across the two rivals.

    The means for each cell are summarized in

    Table 2, so that distress ratings can be

    matched to the choices depicted in Table 1.

    Two main effects were significant, and one

    of the interactions reached significance.

    Sexual infidelity (M 7.73, SD 1.69) was

    more distressing than emotional infidelity(M 6.65, SD 2.03) [F(1, 136) 14.38,

    p< 0.001], and infidelity involving a former

    partner (M 7.48, SD 1.86) was more

    distressing than infidelity with a new person

    (M 6.89, SD 2.02) [F(1, 136) 16.84,

    p< 0.001]. However, the interaction of gen-

    der with rival indicated that women showed

    greater sensitivity to the distinction between

    rivals. Men were equally distressed by both

    rivals [M 6.81, SD 2.01 for new person;

    M 7.10, SD 1.99 for former partner,

    t(70) 1.42, p 0.16], but women were

    more distressed when the rival was a former

    lover [M 7.90, SD 1.63 for former part-

    ner; M 6.99, SD 2.03 for new person,

    t(68) 4.39, p< 0.001].

    Ratings of forgiveness

    The ratings of likely forgiveness

    (1definitely would not, 9definitelywould) for the infidelity were also analyzed

    in a 2 (gender) 2 (infidelity type) 2

    (rival) analysis of variance, with repeated

    measures across the two rivals. The means

    for each cell are summarized in Table 3, so

    that forgiveness ratings can be matched to

    the choices depicted in Table 1 and distress

    ratings in Table 2. The main effects for rival

    [F(1, 136) 4.66, p 0.033] and for type of

    infidelity [F(1, 136) 40.26, p< 0.001] weresignificant, as was the interaction of gender

    with rival [F(1, 136) 7.11, p 0.009].

    Participants believed that they would be

    more likely to forgive emotional infidelity

    (M 5.23, SD 2.41) than sexual infidelity

    (M 3.04, SD 1.98). Forgiveness in reac-

    tion to different rivals revealed an overall

    bias in favor of forgiving when the rival was

    the new person (M 4.28, SD 3.99) com-

    pared to the former partner (M 3.99,SD 2.46), but this was qualified by the

    interaction with gender. Only women

    showed a varied reaction to different rivals,

    with forgiveness more likely when the rival

    Predicting reactions to infidelity from

    investment model variables

    The investment model variables were first

    subjected to a regression analysis to ensure

    that the relationships predicted by the the-

    ory were valid for this sample.2 The three

    predictor variables, satisfaction, invest-

    ments, and quality of alternatives, were

    used to predict commitment. Because of

    some omitted items that appear to follow

    no pattern, there were 134 usable responses to

    2. The Investment Model Scale was administered last.To ensure that the between-group manipulationsdid not affect responses on this measure, analysesof variance were conducted with the InvestmentModel scores as the dependent variables. Therewere no significant effects.

    p< 0.001, R2 0.565]. All three variables

    provided significant unique contributions to

    the prediction of commitment (Table 4).

    The three predictor variables from the

    investment model were then used to predict

    the distress and forgiveness ratings in

    response to the infidelity. Given the gender

    differences in distress and forgiveness rat-

    ings, separate regressions were conducted

    for men and women for each of the four

    separate measures, with the effects of the

    between-group variable, infidelity type,

    removed in a first step of the regression,before the model variables were introduced.

    The goal was to determine whether the

    investment model variables could predict

    reactions above and beyond the effects of

    infidelity type. In predicting distress when

    the rival was a former partner, the invest-

    ment model variables did produce a signifi-

    cant improvement in the regression model

    for women but not for men (Table 5). An

    examination of the contributions by indivi-dual investment model variables revealed

    that the investment variable was the only

    significant predictor for women. For men,

    only infidelity type was a significant pre-

    dictor of distress. No investment model

    variables added significantly to the predic-

    tion of distress, individually or as a set. The

    same pattern emerged when the criterion

    was the distress associated with infidelity

    involving a new person. The investmentmodel variables did significantly improve

    the model for women, but only the invest-

    ment variable was individually significant.

    For men, only infidelity type was related to

    distress. Women reported more distress

    over infidelity when they felt that they had

    invested more in the relationship. Satisfac-

    tion and quality of alternatives did not

    individually contribute a significant amount

    to womens predicted distress.

    The predictions of the forgiveness ratings

    revealed a contribution by the investment

    model variables for both women and men.

    In predicting forgiveness when the rival was

    a former partner, the investment model

    variables improved the prediction for

    women and men. For men, the satisfactionvariable helped most to explain forgiveness,

    but for women, it was investment that

    helped predict forgiveness (Table 6).

    Again, a similar pattern was repeated

    when the rival was a new person, although

    the improvement in prediction was not

    quite significant for men (p< 0.07). Signifi-

    cant individual contributions were again

    made by the satisfaction variable for men

    and the investment variable for women(Table 6). Hence, men were more likely to

    forgive their partner when they were satis-

    fied with their current relationship, while

    women were more likely to forgive when

    they had invested less in their partner. The

    Investment Model predicts a greater rela-

    tionship stability with increasing invest-

    ments; hence, the opposite result would

    have been expectedmore forgiveness

    with more investments. To determinewhether, perhaps, the true relationship is

    nonlinear, the curvilinear relationships

    between investments and forgiveness were

    examined for women. The power curve
