Data collection tools included Luthans's (2007) psychological capital questionnaire, Walks et al.'s (1986) social support, and Riff's short-form psychological well-being (2002). The validity and reliability of all tools have been confirmed in domestic and international studies. After collection, the data were analyzed using SPSS version 24 and AMOS version 26 software. Analyses included descriptive statistics (mean, standard deviation, and frequency) and inferential statistics (structural equations) to test hypotheses. Findings showed that psychological capital and social support have a positive and significant relationship with psychological well-being of married women working in the public sector. These results emphasize that increasing psychological capital and providing social support can significantly contribute to improving women's mental health and psychological well-being
