Traditional masculinity norms significantly impact men's psychological well-being globally. Yet empirical research examining these patterns within Indian socio-cultural contexts remains limited. This study investigates how Indian young adults conceptualize and negotiate masculinity through the lens of Man Box Theory (Promundo, 2017). The research explores how Indian young adults express masculine norms and expectations. It also explores which Man Box domains align with or diverge from Indian cultural contexts. Additionally, it examines the perceived impacts of masculine notions on interpersonal relationships and psychological well-being. To achieve these objectives, semi-structured interviews with participants aged 18-25 years (young adults) across diverse Indian regions were conducted and analysed using Braun and Clarke's Thematic Content Analysis framework. The study adopts the lens of Man Box theory while remaining open to emergent cultural themes specific to the Indian context. Findings reveal how participants articulate masculine pressures, display resistance to traditional masculine norms and express a blend of Western and traditional Indian notions of masculinity. Results indicate connections between adherence to restrictive masculine norms and psychological well-being outcomes, including stress, difficulties in emotion regulation, and quality of interpersonal relationships. Comparative insights also highlight how Indian perspectives on masculinity both link with and split from Western conceptualisations, highlighting culture-specific manifestations and adaptive responses. This study contributes to applied psychology by providing an empirically grounded understanding of masculinity in the Indian context, which can inform the development of culturally appropriate gender-transformative interventions and psychological approaches to health promotion.
