Summary of findings on anxiety disorders

Reference	Predictor variable	Outcome variable	Results (++ < 0·05 adjusted; + < 0·05 unadjusted; − non-significant)
Jakubovski and Bloch (2016) [64]	Perceived social support	Remission; Response (a reduction of at least 40% symptoms at 6 months)	++ ++	Generalised anxiety disorder: Greater amount of social support predicted a higher rate of remission (OR = 1.38, 95% CI Wald 1.09–1.75, p = 0.0067) and a greater rate of response (OR = 1.33, 95% CI Wald 1.10–1.62, p = 0.0040) at 6-month follow-up. Social anxiety disorder: Greater amount of social support predicted a higher rate of remission (OR = 1.716, 95% CI Wald 1.028–2.867, p = 0.0391) at 6-month follow-up, but social support did not predict response. Social support did not predict remission or response for panic disorder or post-traumatic stress disorder
Shrestha et al. (2015) [65]	Perceived social support	Quality of life	++	Main effect of social support was significant such that those with higher baseline social support reported higher average quality of life over time (b (SE) = 0.41 (0.08), p < 0.001)
Dour et al. (2014) [33]	Perceived social support	Anxiety symptoms; Depressive symptoms	++ ++	Direct effects: Relations between perceived social support and depression were bidirectional at all follow-ups, whereas they were unidirectional between perceived social support and anxiety at 6- and 12-month follow-ups. Indirect effects: Intervention led to changes in 6- and/or 12-month perceived social support, that in turn led to subsequent changes in 18-month depression (b = − 0.16, CI [− 0.28, − 0.08], Ratios 10.51%) and anxiety (b = − 0.15, CI [− 0.30, − 0.06], Ratios 8.85%)
