High-risk and impulsive behaviors in conscript soldiers pose a serious challenge to mental health in military environments with individual, familial, and organizational consequences. The present study aimed to provide an explanatory model of these behaviors among conscript soldiers at Imam Hossein Comprehensive University. This research was conducted using a qualitative approach and grounded theory. The Barratt Impulsiveness Scale and the Iranian Adolescent Risk-taking Scale were used as screening questionnaires to select participants. Data were collected through semi-structured interviews with 9 conscript soldiers and were analyzed using MAXQDA 2018 software. The analysis was conducted in three stages of open, axial, and selective coding. In open coding, 298 references were reduced to 218 unique codes. In axial coding, 26 concepts and 13 subcategories were classified into six components of the paradigm model. In selective coding, the core category was identified as (dispatch of accumulated pressure resulting from repressive interaction) The presented model, with the innovative concepts of (repressive interaction) and (dispatch of accumulated pressure) explains the vicious cycle of high-risk behaviors. Structural reform, respectful interaction, and psychological empowerment are among the most important preventive measures.
