Testing a Multidimensional Acculturation Model on Latinos who Completed Substance Abuse Treatment.

Disparities in substance abuse treatment (SAT) utilization and completion suggest that traditional substance abuse models may fall short of addressing the complex needs of Latinos, increasing the odds of relapsing. The need for substance use models that integrate multiple acculturation domains in relation to substance abuse is warranted. The goal of the present study is twofold: a) test a multidimensional acculturation model on Latinos who completed SAT; and b) examine the association between the proposed multidimensional acculturation and days consuming alcohol and illicit drugs in the past six months. A total of 131 participants (Mage=36.15, SD ± 10.5, 86.3% males, 48.1% non-U.S. born with a mean length of stay of 19 years in the U.S. (SD ± 13.71) were interviewed upon completion of SAT. Results from the SEM indicated adequate model fit to the population under study, supporting the use of a multidimensional acculturation approach for this population. Subsequent results from the structured regression analysis suggest that multidimensional acculturation is negatively associated with days using alcohol in the past 6 months. The implications of these findings are discussed.
