Background: Risk factors exploring the link between trauma and Post-traumatic stress disorder (PTSD) have been extensively explored in adults, however, less is known about child and adolescent populations.

Methods: The current meta-analysis aimed to systematically evaluate and summarise the child focused literature to estimate the strength of the relationship between social support and PTSD symptoms following traumatic events.

Results: Fifty primary studies reporting an effect size for the relationship between total social support scale or a source of social support with PTSD were included. A small effect size was found for the relationship between social support and PTSD (r = -0.12, 95% CI -0.16 to -0.07, k = 41), with large heterogeneity (I = 90.3%). The effect sizes between peer support (r = -0.18, 95% CI -0.10 to -0.25, k = 12), family support (r = -0.16, 95% CI -0.09 to -0.24, k = 13) and teacher support (r = -0.20, 95% CI -0.15 to -0.24, k = 5) and PTSD were also small. Moderator analyses indicated that studies reporting on participants exposed to abuse (r = -0.25) and correlations based on univariate data (r = -0.14) had higher correlations and medium heterogeneity. The main effect size was robust to publication bias and study quality.

Limitations: The cross-sectional design of the studies limits the findings and future research using prospective and longitudinal design would help to explain the relationship between social support and PTSD further.

Conclusions: The current review suggests that social support may only play a small role in protecting against PTSD and future research may benefit from exploring the link between post-trauma cognitions and social support.
