Validity and reliability of a strength scale for elderly people in the care cycle

Abstract

This study aimed to develop and examine the validity and reliability of a scale to measure the strength of elderly people in the care cycle.
We prepared 18 questions based on the Strength Model of Rapp and administered an anonymous self-completed questionnaire survey to elderly people(65+ yrs)certified as requiring long-term care and those who were using preventive care services. Valid responses were obtained from 212.
A confirmatory factor analysis yielded an optimal higher-order factor model with aspirations, confidence, competencies, social relations, resources, and opportunities as primary factors and internal resources and external resources as secondary factors.
A moderate significant correlation was observed between the results of the Comprehensive Environmental Questionnaire for the Elderly(CEQ)and the levels of self-esteem, which confirmed the validity of our scale under external criteria.
The ω reliability coefficient was high, confirming the internal consistency of our scale. We expect our scale to enable us to objectively evaluate the strength of elderly people and provide appropriate support.
