title: Reliability of the Lifetime Inventory of Drug Use Consequences (INDUC) in methadone maintenance patients.
abstract: One hundred twenty one opiate-dependent individuals in methadone maintenance treatment at an urban university medical center in the U.S. were administered the Inventory of Drug Use Consequences (InDUC), and 68 subjects provided follow-up assessments at two to six weeks. The sample included 61 (50.4%) women; 86 (71.1%) of the subjects reported that they were White, 29 (24.0%) Black, and six (5.0%) other race. The mean age was 41.9 (SD = 9.7) years. Ninety-nine (81.8%) of participants had used opiates intravenously. INDUC total scores and a short form showed high internal consistency (alpha) and test-retest reliability (ICC) across gender, race, ethnicity, and education, supporting their use as global measures of drug use consequences. The interpersonal scale was also reliable across strata whereas the physical and intrapersonal scales were not reliable. The impulse control and social responsibility scales were stable but not internally consistent.
