The Development of the Adaptive Behavior Scale for Stroke Survivors

Area of Science:

• Rehabilitation Medicine
• Psychometrics
• Neuroscience

Background:

• Stroke survivors' adjustment is a complex, self-directed process.
• Existing tools may not fully capture the multi-dimensional nature of stroke adaptation.
• Developing a specific, psychometrically sound scale is crucial for assessing and supporting survivors.

Purpose of the Study:

• To develop and psychometrically evaluate a new adaptive behavior scale for stroke survivors.
• To create a concise, easy-to-use tool for assessing self-directed adaptation.
• To provide a basis for individualized intervention programs.

Main Methods:

• Item pool generation based on adaptive behavior attributes.
• Content validity assessment by 10 experts.
• Pilot testing and interviews with 10 stroke survivors.
• Administration of a 16-item, five-point Likert scale to 215 stroke survivors.
• Psychometric evaluation including item analysis, confirmatory factor analysis (CFA), and reliability testing (Cronbach's α).

Main Results:

• The final scale consists of 16 items across three factors: optimistic view, activity restructuring, and daily life execution.
• Confirmatory factor analysis supported the three-factor model.
• The scale demonstrated excellent internal consistency, with Cronbach's α = 0.90.
• The scale is suitable for stroke survivors in both subacute and chronic stages.

Conclusions:

• The developed scale is a valid and reliable measure of adaptive behavior in stroke survivors.
• This tool can assist healthcare professionals in assessing survivor adaptation.
• The scale facilitates the development of tailored interventions to enhance stroke recovery and adaptation.
