MISAPSY: Childhood Maltreatment, Food Insecurity, Psychological Distress and Professional Integration Among Socioeconomically Disadvantaged Young Adults

The MISAPSY study (Childhood Maltreatment, Food Insecurity, Psychological Distress and Professional Integration Among Socioeconomically Disadvantaged Young Adults) aims to model the complex interrelations between child maltreatment, trauma exposure, food insecurity, and psychological distress among precarious young adults enrolled in French youth employment and social integration services (Mission Locale). Adopting a methodology structured around three complementary components, this study consists of: (1) a cross-sectional survey to identify key associations ; (2) a qualitative study based on semi-structured interviews exploring psychologists' subjective experiences, and (3) a longitudinal comparative interventional study involving two different support programs to assess and compare the impact of these interventions on participants' food insecurity and psychological well-being. Using a multi-phase design, MISAPSY seeks to move beyond linear risk-factor models by adopting a systemic and network-based approach to mental health and social vulnerability. The study integrates quantitative analyses, including network analyses, qualitative exploration of professional practices, and comparative longitudinal intervention to inform more holistic, equitable, and transferable models of care for vulnerable young adults.
