A Reliability Generalization of the Suinn-Lew Asian Self-Identity Acculturation Scale

Abstract

A reliability generalization was conducted on studies that reported use of the Suinn-Lew Asian Self-Identity Acculturation Scale (SL-ASIA), published between 1987 and 2013. For inclusion in this meta-analysis, each study had to have reported a Cronbach’s alpha reliability coefficient for its sample. Data from 83 Cronbach’s alpha coefficients representing 12,992 participants were analyzed; only 67 out of 193 published studies (43.52%) reported reliability scores for their sample. The reliability scores produced by the SL-ASIA ranged from .62 to .96 with an average of .91 ( SD = 0.07); therefore, all of the reported reliability scores for this instrument were in the acceptable to excellent range. Our results demonstrate that SL-ASIA continues to be an instrument with strong psychometric properties when used with diverse populations, and it is therefore appropriate for continued use with studies on acculturation.
