Development of Self-Active Aging Index (S-AAI) among rural elderly in lower northern Thailand classified by age and gender

Abstract

Abstract This study aimed to develop a Self-Active Aging Index (S-AAI) for the rural community of Thailand using the World Health Organization (WHO) framework, and score it according to age and gender. Overall, 1,098 elderly people were randomly selected. The self-reported questionnaires were categorized into three segments: health, participation, and security according to the WHO framework. An exploratory factor analysis was used to determine appropriate components. The S-AAI comprised 28 indicators and 9 factors: (1) mental/subjective health; (2) physical health; (3) health behavior and chronic disease; (4) vision and hearing; (5) oral health; (6) social participation; (7) stability in life; (8) financial stability; and (9) secure living. The overall S-AAI for all components was 0.65, with the index inversely proportional to age, but with no gender differences. The S-AAI is potentially Thailand's first multi-dimensional interactive aging assessment tool with a unique cultural context for rural areas. Although this tool is valid, it requires reliability testing.
