Similarity of behavior within addict couples. Part I. Methodology and narcotics patterns

The development and initial assessment of a methodology for measuring the similarity of behavioral patterns within addicted couples over the duration of a relationship is presented. Two subsamples of addicts from methadone maintenance programs in southern California were established: one of couples who had a real relationship during their addiction and treatment careers, and a group of pseudocouples (matched as closely as possible) created from unrelated clients in the same programs. Narcotics use, abstinence, and support patterns are analyzed for couples before, during, and after their relationship. When it occurs during the relationship, treatment effects are also analyzed.
