Effects of the Subjective Family Class on the Suicide Ideation of Adolescents: Double Mediating Effect of Social Support and Sense of Coherence

Purpose: The study was conducted to identify the relationship between subjective family class and suicidal ideation and to determine the double mediating effect of social support and sense of coherence on their relationship. Methods: Secondary analysis of data from 2015 Korean Psycho-social Anxiety which was a population-based representative was performed. Double mediating effects of social support and sense of coherence on suicidal ideation were analyzed using the PROCESS macro (model 6) with bootstrapping methods. Results: Subjective family class directly influenced social support ( β =.20, p < .001) and sense of coherence ( β =.10, p < .001). Subjective family class directly influenced suicide ideation ( β =-.08, p < .001). Sense of coherence was directly influenced by social support ( β =.28, p < .001). Suicide ideation was indirectly influenced by subjective family class through social support ( β =-.22, p < .001) and sense of coherence ( β =-.36, p =.001). The size of direct effect of subjective family class on suicide ideation was 0.24 and the total size of indirect effect was 0.12. Conclusion: Intervention to improve social support and sense of coherence is needed to prevent the suicide among adolescents.
