The Development of the Adaptive Behavior Scale for Stroke Survivors.

The adjustment of stroke survivors is self-directed and multi-dimensional. This study developed an adaptive behavior scale for stroke survivors reflecting these characteristics and performed a psychometric evaluation. The item pool was derived based on conceptual attributes and indicators of adaptive behaviors for stroke survivors. Ten experts assessed the content validity. The scale was refined through pilot testing and interviews with 10 stroke survivors. From December 2021 to May 2022, a self-report questionnaire consisting of a five-point Likert scale was administered to 215 stroke survivors visiting a university hospital in S City, South Korea. Item analysis and confirmatory factor analysis were conducted to assess the construct validity; reliability was confirmed using Cronbach's α. The final scale comprised three factors and 16 items: taking an optimistic view, restructuring daily activities to suit oneself, and carrying out one's daily life. The confirmatory factor analysis indicated a good fit for the three-factor model; Cronbach's α coefficient of the scale was 0.90, indicating a very good internal consistency. This easy-to-use, concise self-report scale applies to stroke survivors from subacute to chronic stages, providing healthcare professionals with the basic data needed to assess their adaptation. It may also facilitate individualized intervention program development to improve stroke survivor adaptation.
