A new study of Spanish LGBTIQ+ adolescents shows that feeling connected to family, friends and school reduces depressive symptoms and loneliness, which in turn shape overall well-being and suicidal thoughts. Published in Child Psychiatry & Human Development, the research used statistical modeling to trace exactly how social support translates into better mental health outcomes rather than simply confirming that a correlation exists.
How the study was designed
Researchers collected data in 2024 from 289 adolescents ages 14 to 17 (mean age 15.86), combining 114 panel participants with 175 recruited through snowball sampling. Because this is a non-probability sample, the findings cannot be assumed to represent all LGBTIQ+ youth in Spain or elsewhere, a limitation the authors themselves acknowledge. Participants completed established instruments, including the Social Connectedness Scale, the PHQ-9 depression questionnaire, the Paykel Suicide Scale, and single-item measures of loneliness and well-being. Two cross-sectional structural equation models were then used to test whether depressive symptoms and loneliness acted as mediators between connectedness and mental health outcomes.
Family, friends and school each matter, but differently
Stronger connectedness in all three domains was associated with fewer depressive symptoms, with family showing the largest effect (β = −0.32), followed by friends and school (β = −0.17 each). When it came to loneliness, friendship ties mattered most (β = −0.47), with family connectedness also contributing (β = −0.14). Loneliness itself was linked to lower well-being (β = −0.30). School connectedness stood apart: rather than working mainly through reduced loneliness, it showed a direct positive association with well-being (β = 0.29), suggesting that feeling supported at school may influence how teens evaluate their lives through a separate pathway.
Depression as the key channel to suicidal thoughts
The analysis found a strong link between depressive symptoms and suicidal ideation or behavior (β = 0.57). Once depression was included in the model, the direct statistical relationship between connectedness and suicidal ideation disappeared. In practical terms, the data suggest that social support does not protect against suicidal thoughts directly, but rather by first easing depressive symptoms, which then lowers that risk.
What this means for support efforts
The authors argue the results point toward interventions that strengthen family relationships, peer networks and school climate simultaneously, since each operates through a somewhat different mechanism. Because the study is cross-sectional, it cannot establish cause and effect, and the non-probability sampling method limits how broadly the findings can be generalized. Still, the detailed pathways identified offer a useful framework for schools, clinicians and families seeking evidence-informed ways to support LGBTIQ+ adolescents' mental health.
