Comparisons of behaviors during treatment were made between a sample of women and a sample of men methadone maintenance clients. Women in this study exhibited high motivation for treatment. Overall, however, small differences were found between the sexes with respect to treatment process and outcome measures. The observed differences that were significant included use of substances other than heroin, interpersonal relationships, drug dealing, employment, and criminal behaviors. The differences seemed to be in accordance with traditional sex role expectations. The distinctive behavior pattern of Chicanas demonstrated in this study demands special attention. It is suggested that treatment programs should incorporate more services to meet women-specific needs.

Part I of this series compared characteristics of 546 Chicanos and Anglo men and women methadone maintenance (MM) clients. In Part II, specific differences between Chicanos and Anglos are analyzed, by sex, for each of five stages in the addiction career: preexperimentation, experimentation addiction, initial MM treatment, and posttreatment. The analysis examines narcotic and other drug use, arrest, incarceration and legal supervision histories, criminal involvement, employment, interpersonal relationships, and treatment history. Whereas preaddiction differences between addicts parallel ethnic differences found in the general population, after addiction occurs the similarities are greater than the dissimilarities between ethnic groups, except for Chicanas. Chicanos appear to continue to function as part of their community after addiction, but Chicanas appear to risk becoming marginal. Treatment outcomes for Chicanos were, in general, less successful than for Anglos.

This paper reviews the research literature comparing Chicano (Mexican American) to Anglo heroin addicts. In addition, characteristics of 546 Chicano and Anglo men and women who had been clients of southern California methadone maintenance programs in 1978 are compared. Background factors examined include nativity, family socioeconomic status (SES) and family interpersonal relationships, education, and gang membership. Lifetime characteristics and status at follow-up interview are reported with particular attention to legal status, criminality, employment, and interpersonal relationships. Drug experimentation history and circumstances surrounding narcotics initiation are also compared. Most observed differences prior to addiction are similar to ethnic differences found in the general population. Part II analyzes ethnic differences progressing through five stages of the addiction career.

The similarity of behavioral patterns within addict couples before, during, and after a relationship is the focus of this paper. The correlations between partners in real and artificially constructed (pseudo) couples for employment, criminal activities, and other behaviors are examined. The effect of a relationship on behavior is also assessed before, during, and after treatment. Significant correlations during real relationships were found for employment, welfare, and illegal income. Joint couple entry into treatment appears to be more effective for women than men. Similarity within couples disappears when the relationship ends.
