Modelling Adolescent Loneliness via Empathy, Social Goals and Social Capital: A Self-Determination Theoretical Perspective

Abstract Background Adolescent loneliness is rising and linked to poorer psychosocial outcomes. Self-Determination Theory (SDT) highlights social-cognitive skills and social capital as relevant to social well-being. Using Associational Variable Analysis (AVA), this study examined whether theory-consonant associations among empathy, social goals, and social capital align with lower loneliness. Objective Evaluate the associational structure linking combined empathic concern and perspective-taking (ECPT), social achievement goals, social capital (trust, reciprocity, participation), and loneliness in mid-adolescence, and probe robustness via alternative specifications. Methods Students ( N = 177; M age = 14.19, SD = 0.37) completed self-reports of ECPT, social goals (development, demonstration-avoid, demonstration-approach), social capital, and loneliness. SEM (ML with FIML) tested the hypothesised model with AVA checks (direction-reversed variants; alternative social-capital structures). Complementary simultaneous regression reported semi-partial (unique) associations with loneliness. Results The retained model fit well, χ2 (15) = 21.45, p = .123; CFI = .98; RMSEA = .05, explaining R 2 = .41 of Loneliness. ECPT related positively to Social Development and Demonstration-Avoid Goals. Social Development Goals related positively to Social Capital; Demonstration-Avoid related negatively; Demonstration-Approach showed a small positive association. Social Capital was strongly, negatively associated with Loneliness. Robustness checks produced comparable patterns; semi-partial results indicated Social Capital accounted for the largest unique share ( sr 2 = .21). Conclusions Within an AVA (non-causal) frame, findings are consistent with ECPT functioning as a scaffold aligning with mastery-oriented social goals and richer social capital associations linked to lower loneliness. Longitudinal and intervention research should test temporal ordering, mechanisms, and the roles of diversity and digital social capital.
