Sense of coherence and subjective vitality among adolescents: The mediating role of hope in a four-month half-longitudinal study

A strong sense of coherence is essential for adolescent psychological health, as it fosters hope and enhances subjective vitality. Accordingly, the current study aimed to examine the longitudinal mediating role of hope between sense of coherence and subjective vitality. Participants comprised 308 adolescents aged 13 to 19. The data were gathered in two waves, four months apart. Data were gathered through self-report questionnaires and analysed with cross-lagged panel model for a half-longitudinal design. The present study's findings demonstrated a positive association between sense of coherence and hope, and between hope and subjective vitality, as well as the mediating role of hope in the relationship between sense of coherence and subjective vitality. The results indicated that a sense of coherence fosters hope, which subsequently enhances subjective vitality. This study contributes to the literature by elucidating the mechanism linking the sense of coherence and subjective vitality through hope. It suggests that strategies grounded in sense of coherence may promote adolescents’ subjective vitality by fostering hope.
