Quality versus quantity: acquisition of coping skills following computerized cognitive-behavioral therapy for substance use disorders

Abstract

Aims: To evaluate the changes over time in quality and quantity of coping skills acquired following cognitive behavioral therapy (CBT), and examine potential mediating effects on substance use outcomes.

Design: A randomized controlled trial (RCT) evaluating the effectiveness of a computerized version of CBT (CBT4CBT) as an adjunct to standard out-patient treatment over an 8-week period.

Setting: Data were collected from individuals seeking treatment for substance dependence in an out-patient community setting.

Participants: Fifty-two substance abusing individuals (50% African American), with an average age of 42 years, and a majority reporting cocaine as their primary drug of choice.

Measurements: Participants' responses to behavioral role-plays of situations associated with high risk for drug and alcohol use were audio-taped and rated independently to assess their coping responses.

Findings: There were statistically significant increases in mean ratings of the quality of participants' coping responses for those assigned to CBT4CBT compared to treatment as usual, and these differences remained significant 3 months after treatment completion. Moreover, quality of coping responses mediated the effect of treatment on participants' duration of abstinence during the follow-up period.

Conclusions: These findings suggest that assignment to the computerized CBT program improved participants' coping skills, as measured by independent ratings of a role-playing task. It is also the first study to test and support quality of coping skills acquired as a mediator of the effect of CBT for substance use.
