Abstract

Acculturative stress, resulting from adapting to two or more cultures, is associated with alcohol-related problems among Latinx populations. To inform culturally relevant alcohol research, we developed a reliable and valid short form of the widely used 27-item Multidimensional Acculturative Stress Inventory (MASI) that was maximally associated with alcohol-related problems among Latinx undergraduates. To do so, we used data from 3 US universities (N=693). We used complete enumeration to derive a short form, which computes all possible solutions within item sets and identifies solutions optimized on reliability, correlation with the long form, and external validity (i.e., relations with AUDIT scores). MASI subscales reflecting English Competency Pressures (r= .27), Pressures to Acculturate (r= .11), and Pressures Against Acculturation (r= .19) were all positively associated with alcohol dependence. English Competency Pressures (r= .14) and Pressures Against Acculturation (r= .12) were also associated with alcohol-related problems. No subscales were associated with alcohol consumption (rs ranged from .02 to .09). Our abbreviated MASI can be used as a reliable, efficient acculturative stress measure that can inform culturally relevant alcohol research and improve screening for alcohol-related problems among minority populations. These findings also elucidate culturally-specific predictors of alcohol problems among Latinx populations.
