title: Personality, drug use, and early attrition from substance abuse treatment.
abstract: This study examined the relationships among demographics, personality variables, drug use, and early attrition from substance abuse treatment. Attrition was considered at two time intervals; immediately (after one visit) and after 2 months. One hundred consecutive admissions to a community drug-abuse treatment center were given the MCMI and the SCL-90R following a standard intake interview. Subjects were classified according to their primary drug of abuse, yielding 16 opiate, 16 amphetamine, 34 cocaine, and 29 marijuana abusers. ANOVA's, ANCOVA's, and chi-squares were performed to compare characteristics of the different groups. Immediate Dropouts were less likely to be court mandated than Remainers, but were not different on any other demographic or drug use variable. Remainers had higher scores than Immediate Dropouts on 7 MCMI scales. A significant interaction between drug type, symptom severity, and early attrition was found for amphetamine abusers with high levels of subjective distress as measured by the SCL-90R. These clients dropped out earlier than amphetamine abusers without elevated SCL-90R scores. Analysis also indicated that Long-Term Remainers were less likely to be employed than Dropouts. All other comparisons between these groups failed to produce significant differences. This study confirms earlier research which found a high rate of early attrition from treatment with substance-abusing clients. Results also indicate that severity of psychopathology is not key in predicting attrition; it is more the nature of the disorder that influences client dropout. It is argued that continuation in community treatment is problematic for most substances abusers, and treatment facilities should routinely employ attrition prevention procedures.
