Suinn-Lew Asian Self Identity Acculturation Scale

Construct: Degree of acculturation of Asian populations

Asian-American familyDescription of Measure: The Suinn-Lew Self Identity Acculturation scale (SL-ASIA) was originally developed by Suinn, Ahuna, & Khoo (1992) as a 21-item measure, modeled on the ARSMA, to assess the degree of acculturation of Asian-American clients. Later, the authors added an additional 5 items. The 21-item version can be scored as follows: Add up each answer for each question on the scale, then obtain a total value by summing across the answers for all 21 items. A final acculturation score is calculated by then dividing the total value by 21. The resulting total score can range from 1.00 (low acculturation) to 5.00 (high acculturation). With the 25-item version, the additional items can be classified by examining the answers to #22 and #23 together, #24 and #25 together, and #26 alone.

The SL-ASIA has been used successfully with clients across a wide range of ages. Though it was not specifically designed for older adults, it has been effectively used with this population as well.
