Social support may prevent self‐cutting in adolescence: A 5‐year follow‐up study

Self-cutting is common among adolescents. However, studies examining protective factors are rare. It has been suggested that social support may protect against self-cutting in adolescence. The aim of this study was to investigate the possible association of social relationships with the initiation of self-cutting. Methods The participants were community-dwelling Finnish adolescents (N = 4171) aged 13-18 years at baseline. The follow-up assessment was conducted 5 years later (N = 794). Those adolescents who had self-cut before the baseline assessment (N = 134) were excluded from the analysis, leaving a total of 660 participants to be analyzed. In this group, 37 adolescents initiated self-cutting during the 5-year follow-up period and 623 did not. Cox's proportional hazards models were used with several adjustments for possible confounding factors. Findings A higher age, male gender, good relationships with siblings, weekly meetings with friends, and personal experience of not being lonely associated with the noninitiation of self-cutting during the follow-up period. Good relationships with parents or peers had no association with the initiation of self-cutting. Depressive symptoms mediated the effect of subjective loneliness on initiating self-cutting. Conclusions Social support produced by friends may have a protective effect against self-cutting.
