Predictors of Relapse and Dropout During a 12-Week Relapse Prevention Program for Methamphetamine Users.
In this research, the possible neuropsychological predictors of relapse and dropout of group cognitive behavioral therapy (CBT) for methamphetamine (MA) users were explored. Participants were 42 MA users sentenced by the judicial system to take part in an out-patient relapse prevention program for MA abuse and dependence that employs a CBT model once a week over the course of 12 weeks. Baseline neuropsychological functions were evaluated with the Conners' Continuous Performance Test, Wisconsin Card Sorting Test, Iowa Gambling Task, and Barratt Impulsiveness Scale. All participants had to submit to urine drug tests every week. Of the 42 participants, 69.0% had a MA positive urine screening result at least once throughout the program (relapse), while 40.5% dropped out of the treatment program prior to its completion. Short duration of MA abstinence at baseline and poor attention predicted relapse. Predictors of dropout included being unmarried and having risky decision making. Findings may be helpful for clinicians, who can screen for the aforementioned risk factors and provide strategies for high-risk patients to help prevent relapse and dropout among MA users in treatment programs.
