Measurement Invariance and Application of an Alcohol-Related Consequence Scale for American Indian Adolescents

Depressive symptoms, alcohol use, and alcohol-related consequences: the moderating role of gender among American Indian adolescents

OBJECTIVES

Depression, alcohol use, and alcohol-related consequences are experienced disproportionately by American Indian (AI) adolescents. The co-occurrence of depression and alcohol use is clinically relevant, as it is associated with increased risk for suicide, among other negative consequences. Understanding how the association between depressive symptoms and alcohol use and related consequences is influenced by gender is important to understand for whom intervention efforts might be particularly relevant. Thus, the present study seeks to evaluate gender differences in these associations among AI adolescents.

METHODS

Participants were a representative sample of AI adolescents (N = 3,498, Mage=14.76, 47.8% female) residing on or near reservations who completed self-report questionnaires in school classrooms. Study activities were approved by IRB, school boards, and tribal authorities.

RESULTS

The interaction of depressive symptoms and gender was significant in predicting past-year alcohol use frequency (b=.02, p=.02) and, among youth reporting lifetime alcohol use, alcohol-related consequences (b=.03, p=.001). Analysis of simple slopes revealed that, for females, depressive symptoms were significantly associated with past-year alcohol use frequency (b=.02, p<.001) and alcohol-related consequences (b=.05, p<.001). For males, depressive symptoms were only significantly associated with alcohol-related consequences (b=.02, p=.04), and this effect was weaker than for females.

CONCLUSIONS

Results of the present study may inform the development of gender-sensitive recommendations for the assessment and treatment of alcohol use and alcohol-related consequences among AI adolescents. For instance, results suggest that treatments focusing on depressive symptoms may subsequently reduce alcohol use and related consequences for female AI adolescents.

Cultural identity affiliation and alcohol use and related consequences among American Indian and White adolescents: A latent profile analysis

BACKGROUND

Adolescent alcohol use is a significant public health concern and rates of alcohol use are higher among American Indian (AI) adolescents than national samples of non-AI youth. A potential factor in understanding AI alcohol use is cultural identity, which can vary widely based on experiences of historical trauma. We used latent class analysis to examine cultural identity in AI and White adolescents and their alcohol use outcomes in relation to the latent class solutions.

METHODS

The samples included 3189 AI adolescents (M_age  = 14.76, 48.9% female) and 1579 White adolescents (M_age  = 15.56, 48.7% female) living on or near a reservation. Participants completed self-report measures of AI and White cultural identity affiliation, alcohol use, and alcohol-related problems. We examined (1) the best-fitting latent class solution with respect to American Indian (AI) and White cultural identity; (2) equivalence of the latent class solution; and (3) alcohol use outcomes across the optimal latent class solution.

RESULTS

Latent profile analyses indicated an optimal 3-class solution in both the AI and White samples, which differed by level of affiliation with AI and White cultural identity. While the optimal number of classes were similar across racial groups (configural profile similarity), the nature of the classes differed (structural profile dissimilarity). The three classes represented low overall scores on AI and White cultural identity (Marginalized), a mixture of high and low scores on AI and White cultural identity (Third Culture), and overall high scores on AI and White cultural identity (Bicultural). Alcohol-related problems predicted membership in the Third Culture class compared with the Marginalized class and the Bicultural class. Specifically, youth in the Third Culture class reported significantly fewer alcohol-related problems than youth in the Marginalized and Bicultural classes. Alcohol use did not predict latent class membership.

CONCLUSIONS

The future-oriented nature of the Third Culture class may provide protection against adverse alcohol-related outcomes. Research is needed to test interventions that target greater future orientation and future plans to integrate culture into adolescents' lives.
