<p>The present study aims to develop and validate a gender-sensitive financial well-being scale specifically designed for Indian working women, addressing limitations of existing gender-neutral measures that fail to capture the relevant dimensions of women’s financial lives. A sequential, multi-phase mixed-method design was adopted. An extensive literature review and in-depth interviews were used to conceptualize women’s FWB and generate an initial item pool. Subsequent studies included item refinement, expert review for content and face validation, followed by exploratory and confirmatory factor analysis to assess psychometric properties of the scale. The findings confirm a 15-item, four-dimensional scale of financial well-being with strong psychometric properties. Grounded in feminist economics, capability, empowerment, and relational autonomy theories, the results demonstrate that working women’s financial well-being extends beyond financial adequacy to include autonomy, security, and satisfaction. This study is among the first to conceptualize and empirically validate a financial well-being measure for working women in an emerging economy context. It advances the literature by integrating women’s lived experiences and offering a robust, context-sensitive tool for research, policy, and practice.</p>
