Differential effects of treatment modality on psychosocial functioning of cocaine-dependent men

Changes in psychosocial functioning,including depression. anxiety, somatiza tion, obsessive-compulsiveness. interpersonal sensitivity, confidence in th e ability to resist taking drugs in different situations, and social adjust ment are examined for male veterans entering treatment for cocaine dependen ce. The sample was comprised of African Americans (66%). Hispanics (8%). an d Whites (26%) with a mean age of 35 years at intake. Participants were ass essed at the end of 1 year and 2 years: during the follow-up period, partic ipants utilized different combinations of treatment modalities. Paired t-te sts showed significant improvement between intake and follow-up, both at th e end of 1 year and 2 years, on the Beck Depression Inventory, on the depre ssion, anxiety, obsessive-compulsiveness, and interpersonal sensitivity sco res of the Symptom Check List (SCL-58), and in four role areas of social ad justment on the Social Adjustment Inventory. There were no significant diff erences between intake and follow-up on the somatization subscale of the SC L-58 and on the Drug Taking Confidence Questionnaire (DTCQ). Measures taken at Year 2 were not significantly different from Year 1. Repeated measures analysis of variance revealed that treatment modality did not differentiall y affect psychosocial functioning on nearly all measures, except on somatiz ation, confidence in the ability to resist taking drugs in different situat ions. and social adjustment involving leisure time. However, a combination of inpatient. high-intensity outpatient, and self-help group participation and a combination of outpatient and self-help group participation were bett er than a combination of inpatient, low-intensity outpatient, and self-help participation in increasing the confidence in the ability to resist cocain e use in different situations and to reduce symptoms of somatization.
