This study examined whether young Iranian women’s perceived control and self-efficacy, as a component of cognitive social capital, predicts health and well-being. A total of 391 women aged between 18 and 35 years completed a survey including scales measuring control and self-efficacy and health outcomes including quality of life, satisfaction with life and lifestyle behaviours. Statistical analyses indicated that participants had low perceived control and influence over community affairs together with high perceived control over their personal lives. Multiple regression analyses indicated the predictive role of control and self-efficacy for well-being outcomes suggesting the potential role for health interventions targeting control and self-efficacy.
