Objectives: Successful aging is an interdisciplinary concept. Despite the great body of literature on successful aging, few studies have focused on its subjective and multidimensional measurements. Thus, the present study aimed to develop an instrument to measure self-perceived successful aging. Methods: We used a mixed method approach. The successful aging dimensions were explored through an integrative review and qualitative study among ۶۴ older adults. Based on the obtained qualitative data, initial item pool was designed and its content validity was evaluated. A quantitative survey among ۶۰۰ older adults and exploratory factor analysis was applied to test the structural validity of the instrument. Results: The EFA results indicated that the instrument loaded into seven factors; “psychological well-being”, “social support”, “financial and environmental security”, “spirituality”, “physical and mental health”, “functional health”, and “health-related behavior”. In addition, the instrument had a high degree of reliability coefficients. Discussion: The obtained results indicated methods of measuring successful aging, as well as the importance of generating social policy in the area of aging well; researchers should consider all dimensions of successful aging at individual and social levels.
