Validity of Temporal Measures as Proxies for Measuring Acculturation in Asian Indian Survey Respondents

There are few validated acculturation measures for Asian Indians in the U.S. We used the 2004 California Asian Indian Tobacco Survey to examine the relationship between temporal measures and eleven self-reported measures of acculturation. These items were combined to form an acculturation scale. We performed psychometric analysis of scale properties. Greater duration of residence in the U.S., greater percentage of lifetime in the U.S., and younger age at immigration were associated with more acculturated responses to the items for Asian Indians. Item-scale correlations for the 11-item acculturation scale ranged from 0.28–0.55 and internal consistency reliability was 0.73. Some support was found for a two-factor solution; one factor corresponding to cultural activities (α = 0.70) and the other to social behaviors (α = 0.59). Temporal measures only partially capture the full dimensions of acculturation. Our scale captured several domains and possibly two dimensions of acculturation.
