Predictors of Relapse and Dropout During a 12-Week Relapse Prevention Program for Methamphetamine Users

Area of Science:

• Neuropsychology
• Addiction Psychiatry
• Behavioral Therapy

Background:

• Methamphetamine (MA) abuse is a significant public health issue.
• Cognitive Behavioral Therapy (CBT) is a common treatment for MA dependence.
• Relapse and dropout rates remain high in MA treatment programs.

Purpose of the Study:

• To identify neuropsychological predictors of relapse and dropout in MA users in a group CBT program.
• To inform clinical practice for improving treatment retention and success.

Main Methods:

• 42 MA users in a 12-week outpatient relapse prevention program using CBT.
• Baseline assessment of neuropsychological functions (attention, executive function, impulsivity).
• Weekly urine drug tests to monitor MA relapse.

Main Results:

• 69% of participants relapsed at least once.
• 40.5% dropped out of the program.
• Short MA abstinence duration and poor attention predicted relapse.
• Unmarried status and risky decision-making predicted dropout.

Conclusions:

• Neuropsychological deficits, particularly in attention and decision-making, are significant predictors of relapse and dropout in MA users.
• Clinicians can use these findings to identify at-risk individuals.
• Targeted interventions can be developed to improve treatment outcomes for MA users.
