Sense of coherence and health in adolescents: a longitudinal cohort study.

OBJECTIVE: Several studies indicate an association between adolescents' sense of coherence (SOC) and health. However, a few longitudinal studies have been conducted. The aim of the study was to analyze the association between SOC and health among adolescents during secondary education. METHODS: Participants of longitudinal cohort study were followed by questionnaires at the age of 15 (N = 441), and 17 (N = 354). The data were analyzed using the methods of descriptive and inferential statistics. We used hierarchical regression to examine significant predictors of health. RESULTS: Adolescents' SOC was stable during the analyzed two-year period (128.84 ± 22.17; 129.24 ± 23.06). A strong significant positive correlation was found between SOC and mental health (r = 0.635, p<.001; r = 0.670, p<.001). A significant difference was found between adolescents with a low SOC and those with a high SOC in physical functioning (p<.018), general health (p<.001), vitality (p<.001), social functioning (p<.001), emotional role functioning (p<.013) and mental health (p<.001). Boys had higher SOC and most of the health dimensions. Having a stronger SOC, being male, and living with both parents were predictors of better mental health. CONCLUSIONS: Sense of coherence was a significant and stable factor associated with mental health. Thus, salutogenic interventions for improving the sense of coherence during adolescence should be explored.
