Addition of cue exposure to cognitive-behaviour therapy for alcohol misuse: a randomized trial with dysphoric drinkers.

AIM: To test whether addition of moderation-orientated cue exposure (CE) or CE after dysphoric mood induction (emotional CE, ECE) improved outcomes above those from cognitive-behaviour therapy alone (CBT) in people who drank when dysphoric. DESIGN: Multi-site randomized controlled trial comparing CBT with CBT + CE and CBT + ECE. SETTING: Out-patient rooms in academic treatment units in Brisbane and Sydney, Australia. PARTICIPANTS: People with alcohol misuse and problems controlling consumption when dysphoric (n = 163). Those with current major depressive episode were excluded. INTERVENTION: Eight weekly 75-minute sessions of individual treatment for alcohol problems were given to all participants, with CBT elements held constant across conditions. From session 2, CBT + CE participants resisted drinking while exposed to alcohol cues, with two priming doses of their preferred beverage being given in some sessions. After an initial CE session, CBT + ECE participants recalled negative experiences before undertaking CE, to provide exposure to emotional cues of personal relevance. MEASUREMENTS: Alcohol consumption, related problems, alcohol expectancies, self-efficacy and depression. RESULTS: Average improvements were highly significant across conditions, with acceptable maintenance of effects over 12 months. Both treatment retention and effects on alcohol consumption were progressively weaker in CBT + CE and CBT + ECE than in CBT alone. Changes in alcohol dependence and depression did not differ across conditions. CONCLUSIONS: These data do not indicate that addition of clinic-based CE to standard CBT improves outcomes. A different approach to the management of craving may be required.

Innovative approaches to intervention for problem drinking.

PURPOSE OF REVIEW: To critique the recent literature on telephone, correspondence-based, and computerized interventions for alcohol problems, which enhance or substitute for practitioner-delivered treatments. RECENT FINDINGS: There is an unmet need for screening, assessment and intervention for alcohol problems, in part because of the difficulty in accessing such treatment within the current health care system. Research on the efficacy of correspondence or electronic (for example Internet-based) interventions is beginning to emerge. In the period 2003-2004 we identified nine acceptability or feasibility studies of these approaches and seven efficacy trials covering a wide range of settings. These modes of intervention are acceptable to patients and the public, and with careful planning, can be implemented in a variety of settings. Treatment trials demonstrate the efficacy of these interventions in reducing hazardous drinking by university students, in delaying initiation of heavy drinking in children and adolescents, and, intriguingly, in addressing insomnia among recovering alcoholics. SUMMARY: There is strong support among potential users for alcohol interventions that employ telephone assistance, written correspondence, and the Internet. These new technologies offer the prospect of increasing the reach of interventions for problem drinking and being cost-effective alternatives or supplements to face-to-face health service delivery.

Development of a Controlled Drinking Self-Efficacy Scale and appraising its relation to alcohol dependence.

There is no specific self-efficacy measure that has been developed primarily for problem drinkers seeking a moderation drinking goal. In this article, we report the factor structure of a 20-item Controlled Drinking Self-Efficacy Scale (CDSES; Sitharthan et al., 1996; Sitharthan et al., 1997). The results indicate that the CDSES is highly reliable, and the factor analysis using the full sample identified four factors: negative affect, positive mood/social context, frequency of drinking, and consumption quantity. A similar factor structure was obtained for the subsample of men. In contrast, only three factors emerged in the analysis of data on female participants. Compared to women, men had low self-efficacy to control their drinking in situations relating to positive mood/social context, and subjects with high alcohol dependence had low self-efficacy for situations relating to negative affect, social situations, and drinking less frequently. The CDSES can be a useful measure in treatment programs providing a moderation drinking goal.

Efficacy of moderation-oriented cue exposure for problem drinkers: a randomized controlled trial.

The effectiveness of cue exposure following a priming dose was compared with cognitive-behavioral intervention in a community sample of problem drinkers. Participants were randomly allocated to 1 of the 2 conditions and received a mean of 5.84 (SD = 2.69) sessions. A psychologist blind to treatment condition conducted an 8-month follow-up. Compared with pretreatment levels, significant decreases in alcohol consumption were evident posttreatment and maintained at follow-up for both groups. Reductions in severity of dependence, impaired control, and alcohol-related problems were also evident for both groups at follow-up. No differences in outcome associated with initial severity of alcohol dependence were apparent. The results raise the issue of the appropriateness of reserving a goal of controlled drinking for those with relatively mild alcohol problems and low alcohol dependence.
