ABSTRACT
Vulnerable populations have been among the most affected by the social consequences of the COVID-19 pandemic; among those, young people and sexual and gender minorities have seen their situation exacerbated by new specific regulations. The aim of the present study was twofold: first, to assess the role of family climate, concerning participants' LGBT+ status during lockdown restrictions, in mediating the impact of the COVID-19 pandemic on personal quality of life and mental health (stress, depression, and anxiety); second, to assess how individual stable traits can moderate the relationship between the individual impact of COVID-19 on mental health outcomes. A total of 407 young adults aged 18 to 35 (M age = 25.03 years; SD = 4.68) who self-identified as being part of a sexual or gender minority took part in this study. Results highlight the association between negative family climate and internalizing symptoms of psychological distress, and its role as a partial mediator of the relationship between the impact of the COVID-19 pandemic at the individual level and mental health outcomes. Additionally, low personality trait levels of neuroticism significantly decreased the strength of the relationship between LGBT+ status during blocking restrictions and internalizing symptoms.
