Social Network Analysis of Diffusion Among American Indian Youth in a Culturally Adapted, Family-focused Prevention Program.

Diffusion can contribute to the spread of preventive intervention effects from participants to non-participants, but best practices for randomized trials prevent contamination of conditions. These practices conflict with cultural values of community benefit, which are salient among American Indians. This study embedded social network measures within a randomized trial of the Bii-Zin-Da-De-Dah (BZDDD) family-focused prevention program to characterize youth's social networks, describe the nature and content of sharing, and test for diffusion effects on cultural engagement (ethnic identification, cultural socialization, cultural practices) and substance use. Participants were 256 American Indian youths enrolled in the trial who provided self-reports of their social networks and indicated whether specific program content was shared with or received from others, while completing cultural engagement and substance use questionnaires across three waves. Results indicated that social networks were comprised mainly of peers and same-age family members (e.g., cousins). Program sharing was not uncommon. For example, 51% of responding intervention youth reported talking with non-participants about BZDDD at wave 2, typically (53%) with similar-age friends and family who were, most often (71%), out of the home. Evidence for diffusion effects was limited, but did indicate that control youth who had some exposure to BZDDD had a significantly higher average cultural/ethnic identity scale score at wave 2 and were more likely to ask an elder for advice than control youth who had no BZDDD exposure in adjusted analyses. Findings illustrate the value of measuring and testing for potential effects of diffusion in prevention trials with American Indians.

Borderline personality disorder and Axis I psychiatric and substance use disorders among women experiencing homelessness in three US cities.

PURPOSE: In this study, we report prevalence rates of borderline personality disorder (BPD) and Axis I psychiatric and substance use disorders among randomly selected women who were experiencing episodes of homelessness in three US cities. METHODS: The sample consists of 156 women, 79 from Omaha, NE, 39 from Pittsburgh, PA, and 38 from Portland, OR. It included 140 women from shelters and 16 women from meal locations. Latent class analysis was used to evaluate BPD symptoms. RESULTS: A large majority of the women (84.6 %) met criteria for at least one lifetime psychiatric disorder, about three-fourths (73.1 %) met criteria for a psychiatric disorder in the past year, and 39.7 % met past month criteria for a psychiatric disorder. Approximately three-fourths of the sample (73.7 %) met lifetime criteria for at least two disorders, about half (53.9 %) met criteria for at least three lifetime disorders, and approximately one-third (39.1 %) met criteria for four or more disorders. Latent class analyses indicated that 16.7 % of the women could be categorized as low self-harm BPD and 19.9 % high self-harm BPD. CONCLUSIONS: In shelters and in treatment settings, these women will present with complex histories of multiple serious psychiatric disorders. They are highly likely to manifest symptoms of BPD, post-traumatic stress disorder, and substance abuse disorders in addition to other psychiatric symptoms which will add to clinical complications.

Cultural considerations in adolescent suicide prevention and psychosocial treatment.

Ethnic groups differ in rates of suicidal behaviors among youths, the context within which suicidal behavior occurs (e.g., different precipitants, vulnerability and protective factors, and reactions to suicidal behaviors), and patterns of help-seeking. In this article, the authors discuss the cultural context of suicidal behavior among African American, American Indian and Alaska Native, Asian American and Pacific Islander, and Latino adolescents, and the implications of these contexts for suicide prevention and treatment. Several cross-cutting issues are discussed, including acculturative stress and protective factors within cultures; the roles of religion and spirituality and the family in culturally sensitive interventions; different manifestations and interpretations of distress in different cultures; and the impact of stigma and cultural distrust on help-seeking. The needs for culturally sensitive and community- based interventions are discussed, along with future opportunities for research in intervention development and evaluation.

Sequential progression of substance use among homeless youth: an empirical investigation of the gateway theory.

We examined the sequence of substance-use initiation in 375 street youth (age 13-21) who were interviewed from 1994-99 in Seattle, Washington. Based on the "gateway theory," participants were categorized into six profiles to describe the order in which they initiated use of various substances (i.e., alcohol, marijuana, other drugs), or classified as nonprogressors if they had not tried all three classes of drugs. Youth progressing in the hypothesized gateway order (i.e., alcohol preceding marijuana, followed by other drugs) initiated their use at an earlier age than youth who had not progressed through all three substance classes. However, there was no relationship between a substance initiation profile and current substance-use. Implications include the recognition that street youth may follow different patterns of use than normative groups, and that interventions geared toward youth who use substances heavily must include contextual factors, in addition to substance-use history.
