Learning Objective 1: The leaner will be able to understand importance of measure of autonomy among older adults.

Learning Objective 2: The leaner will be able to understand the process of development of the Perceived Enactment of Autonomy Short version.

Purpose: Concise assessment of Perceived Enactment of Autonomy (PEA) among older adults is needed to examine their own ability autonomously in meeting needs for both dependence and independence. The aim of this study was to develop the Perceived Enactment of Autonomy Short version in Japanese.

Methods: PEA developed by Hertz (1991) contains 31 positively and negatively worded statements. There are 3 subscales: Voluntariness, Individuality and Self-Direction. Analyzed was internal reliability among 220 older adults. Concurrent validity was examined between PEA and PEA Short version.

Results: After face validity and item analysis, 13 of 31 items were chosen for PEA Short version. Cronbach’s alpha of PEA Short version was .922 and for subscales were .788 for Voluntariness (4 items), .817 for Individuality (5 items), and .800 for Self-Direction (4 items). Concurrent validity was shown that PEA and PEA Short version was significant related (r=.834, p<0.001), and for subscales were Voluntariness (r=.603, p<0.001) and Self-Direction (r=.656, p<0.001).

Conclusion: PEA Short version had satisfactory reliability and validity. It can be used to measure autonomy concisely in the Japanese older adults.
