Development of a new scale for measuring acculturation: the Taiwan Aboriginal Acculturation Scale (TAAS)

As part of the Taiwan Aboriginal Study Project (TASP), a new acculturation scale (the Taiwan Aboriginal Acculturation Scale, or TAAS) has been developed among the aboriginal minorities of Austronesian origin in Taiwan. The design of the original 54 items was based on Milton Gordon's concept of assimilation in association with a careful consideration of cross-cultural validity. These items were administered to 144 subjects stratified by age and sex who were randomly sampled from four major Taiwanese aboriginal groups. Item analysis and factor analysis were applied to select an 18-item scale which has three subscales (factors): cultural assimilation, social assimilation, and social attitude. Results of validity and reliability studies of the TAAS were found to be acceptable. The development of TAAS demonstrates the applicability of the concept of acculturation as a process that involves changes both in attitude, and in behaviour, to non-western societies.
