Therefore, for effective interventions to enhance the quality of later life, a scale to measure ego-integrity in older adults is necessary. This study was carried out to develop a scale to measure ego-integrity in older adults.
Methods: This study utilized cronbach's alpha in analyzing the reliability of the collected data and expert group, and factor analysis and item analysis to analyze validity.
Results: Seventeen items were selected from a total of 21 items. Cronbach's alpha coefficient for internal consistency was .88 for the 17 items of ego-integrity in the older adults scale. Three factors evolved by factor analysis, which explained 50.71% of the total variance.
Conclusions: The scale for measuring ego-integrity in Korean older adults in this study was evaluated as a tool with a high degree of reliability and validity.
