Brief summary
This study was the first to examine the efficacy of a psychological treatment, cognitive behaviour therapy, was in reducing methamphetamine use and depression among a group of people who were regular users of methamphetamines. It was hypothesised that people who recieved four sessions of treatment would make superior reductions in methamphetamine use and depression relative to those who received two treatment sessions, and that those who receive the four- and two-session treatments would report superior improvements in depression and reducation in methamphetamine use relative to the control.
Interventions
Participants were randomly assigned to either an active treatment (two or four sessions of CBT in addition to a self-help booklet) or control condition (self-help booklet alone). The self-help booklet was developed by the National Drug and Alcohol Research Centre (NDARC, 2001). Sessions were delivered in person at central research or local health clinics on a once weekly basis. Session 1 occurred immediately following the initial assessment and randomization, with participants returning for a further one or three sessions on a weekly basis depending on whether allocation was to the 2- or 4-session treatment. Four-session cognitive behaviour therapy condition A therapist manual (Baker, Lee, Kay-Lambkin, Claire & Jenner, 2003), revised and expanded from that used in the pilot study (Baker et al., 2001) and a self-help booklet (NDARC, 2001) guided treatment sessions, which focused on developing skills to reduce amphetamine use. Sessions were conducted individually and lasted 45-60 minutes. Session content included role-plays and take home exercises for practising skills. The first session involved a motivational interview (Miller & Rollnick, 2002; Miller, Zweben, DiClemente & Rychtarik, 1992) to increase motivation to reduce amphetamine use. The following sessions focused on cognitive-behavioural coping strategies and relapse prevention, using techniques developed by Marlatt and Gordon (1985). The second session focused on identifying high-risk situations for amphetamine use. In the third session, participants were taught how to reduce craving with progressive muscular relaxation and coping self-talk. The fourth session focused on coping with lapses and developing a coping drill to use in high-risk situations following any future lapses. Two-session cognitive behaviour therapy condition The procedure and content of the first two sessions was the same as described above for the longer intervention. Participants were also given the same self-help booklet as the intervention group (NDARC, 2001) which details amphetamine related harms and suggestions for reducing amphetamine use.
