‘Problem drug users’ as welfare claimants: a discourse analytic study
Unexpected change of focus in summer 2010

New focus on use of contingency management to promote hepatitis B vaccination among people in treatment for heroin dependence
Statement of the researchMy thesis focuses on the use of contingency management (CM) to promote hepatitis B vaccination among people in treatment for heroin dependence. It is underpinned theoretically by ideas introduced by Michel Foucault. The thesis is in two inter-related parts. First, a ‘macro’ analysis of the rationalities of government within which the use of CM to promote hepatitis B vaccination among heroin users is embedded. Second, a ‘micro’ analysis of technologies of power and technologies of the self apparent in drug service consultations in which CM is used to promote hepatitis B vaccination among heroin users.
Background to the research
Illicit heroin use a leading health problem
Much of physical damage associated with injecting and sharing injecting equipment
Blood borne viruses from sharing equipment
IDUs largest group at risk of HBV infection in England and Wales (Hahne et al. 2004)
Hepatitis B (HBV) a preventable disease
DH recommends all IDUs vaccinated against HBV infection (DH 2007)
UK drug policy, drug treatment and harm reduction
Current UK drug strategy Reducing demand, restricting supply, building recovery: supporting people to live a drug free life (HM Government 2010)
Pharmacological treatments for illicit heroin use effective but potential individual and public health benefit not produced because of high levels of attrition
Physical health interventions for drug treatment populations fail to deliver full benefit due to poor completion of those interventions
UK drug policy and contingency management
Recommended that while pharmacological approaches are the primary treatment option for illicit opiate use psychosocial interventions should comprise ‘an important element of the overall treatment package’ (NICE 2007)
Recommended that drug services should introduce contingency management programmes to reduce illicit drug use and promote engagement with services for people receiving methadone maintenance treatment (DH 2007; NICE 2007)
Introducing contingency management
Use of incentives
Reinforcement theory
Reward plus positive verbal reinforcement
Adjunct to drug treatment and harm reduction interventions
US evidence for effectiveness of CM
Recommendations for use in the UK
Two approaches to positioning contingency management
Positioning contingency management: 1. as evidence-based
Mainstream approach
Evaluating the effectiveness of CM as an adjunct to drug treatment or harm reduction
Evidence-based policy
Systematic review
Randomised controlled trial: gold standard
Used methodology and methods of systematic review to demonstrate how CM interventions:
Are evaluated in contemporary drug policy research
Acquire the label ‘evidence-based’
Positioning contingency management: 2. within a Foucauldian framework
Alternative approach
‘Macro’ analysis of rationalities of government within which use of CM to promote heroin users’ engagement with hepatitis B vaccination is embedded
Key concepts: problematisations; rationalities of government
Problematising drug use: from addiction to harm
The problem of addiction
Prioritising public health: the question of harm
Rationalities of government: from welfarism to neo-liberalism
Neo-liberalism and harm reduction
Contingency management, ‘nudge’ and soft paternalism
Foucauldian discourse analysis (FDA) methodology
‘Micro’ analysis of discursive activity in consultations in which CM is used to promote heroin users’ engagement with hepatitis B vaccination
Discourse, power and knowledge
The subject and research
Technologies of power; technologies of the self
Health care consultation
FDA method: ConMan Programme
Developing a UK Evidence Base for Contingency Management in Addiction Treatment: Incentive-based interventions to improve treatments to reduce drug use and associated harms
Broad aim: To evaluate the feasibility, acceptability and clinical and cost-effectiveness of CM interventions in NHS drug treatment settings
FDA method: ConMan Module 2
Cluster randomised controlled trial of contingency management targeting increased completion of hepatitis B vaccination amongst people in treatment for heroin dependence
Aim: To measure the effectiveness of two voucher-based CM schedules in increasing the proportion of service users who initiate and complete a super-accelerated HBV vaccination schedule when compared against a control intervention (same schedule; no incentive)
FDA method: empirical data Audio recordings of consultations between drug
service users and nurses in which CM is used to promote the uptake of hepatitis B vaccinations
Approx. 192 service users
12 sites across 4 NHS foundation trusts; 3 trial arms / clusters (CM-fixed; CM-escalating; control)
1-4 blood borne virus / key worker nurses per site
0-3 consultations (vaccinations) per service user
(Potentially) dataset of nearly 600 consultations
Primary outcome data, demographic and service information
FDA preliminary analysis: research question
Broad research question:
How does power / knowledge function within the context of consultations in which CM is used to promote the uptake of hepatitis B vaccinations among people in treatment for heroin dependence?
FDA preliminary analysis: aims
More specific aims:
To identify the technologies of governmentality -technologies of power and technologies of the self - at work in these consultations
To describe (a) the components of these different technologies / how these different practices are achieved, and (b) the interplay between the different technologies of governmentality
FDA preliminary analysis: method
N=18 service users / cases
N total = 28 (18 service users + 10 nurses)
36 recordings
Sampled to capture the full range of interventions (3 trial arms), primary outcomes (1-3 consultations), gender differences
Recordings transcribed verbatim professionally where possible (within resource constraints); features of consultations summarised and extracts of special interest transcribed verbatim for remaining recordings
Coding and analysis
Focused listening / reading: framed and guided by theoretical and methodological underpinnings of the empirical analysis and the thesis more broadly
On second listening-reading: notes about interesting features of the interaction (first cycle coding)
Second cycle coding: more specific attention to the research aims; that is, to identifying and describing technologies of governmentality and their relationships to one another
Analysis proper: coding in NVivo 8
Preliminary findings: identifying technologies of governmentality
Technologies of power within consultations include:
Administering the HBV vaccination
Delivering the CM intervention
Supplying harm reduction advice
Making referrals
Key working
Performing administrative tasks
Making ‘small talk’ (facilitates information-gathering, promotes familiarity and trust)
Preliminary findings: describing technologies of governmentality
Features of technologies of power include:
Nurses’ use of positive reinforcement throughout the consultation (not just in relation to the vaccination)
Nurses’ positioning of service users as ‘harm reducers’ (capacity for self-government)
Nurses’ positioning of service users in relation to control of and responsibility for heroin use is ambivalent
Nurses production of a non-judgmental self
Future analysis
1. Develop the preliminary method for sampling, coding and analysing consultations to perform analysis proper with the full dataset
2. Perform a dispositif (apparatus) analysis:
Foucault’s work prescribes both a ‘macro’ and a ‘micro’ approach
Dispositif analysis describes the connections or relationships between elements at these two levels
Original contribution to knowledge generated by thesis
1. Soft paternalism and its operationalisation within current UK health and social policy as ‘nudge theory’ has to date received little academic attention in relation to the topic of illicit drug use. I plan to develop further my Foucauldian account of the evolution of the relationship between UK drug policies and ‘nudge theory’. This development will make a significant contribution to work focusing on substantive examples of the application of ‘nudge theory’.
Original contribution to knowledge generated by thesis
2. I plan to develop a mode of FDA grounded firmly in the concepts of: 1. technologies of governmentality (technologies of power and technologies of the self); and 2. the dispositif. This development will make a significant contribution in the area of poststructuralist methodologies.
