Assessing the validity of the American Indian Enculturation Scale in Alaska Native adults interested in reducing alcohol use

The American Indian Enculturation Scale (AIES) was developed for American Indian populations to measure connection to traditional culture, but it has not been evaluated in Alaska Native people. While American Indian and Alaska Native individuals are grouped together, significant differences exist between groups. As a part of a randomized controlled trial for contingency management to reduce alcohol use, 160 Alaska Native adults completed the AIES. The confirmatory factor analysis indicated that a one-factor, 15-item version of the AIES, removing items 1 and 2 and correlating items 8 and 10, was a reliable (15 items; alpha = 0.896) and valid measure in this sample (chi 2 [89] = 155.788, p<.001; CFI = 0.903; TLI = 0.886; RMSEA = 0.068 [90% confidence interval {CI} 0.050-0.086]; p<.001; SRMR = 0.060). The study provides limited evidence of enculturation's structural validity, as measured by the AIES, for Alaska Native adults. Future confirmatory work and potential adaptation is needed to evaluate the empirical utility of the AIES for Alaska Native individuals seeking help to reduce alcohol use.
