Estimates are presented as OR (SE) for ideation presence (zero inflation part) and RR (SE) for ideation severity and are coded such that ORs and RRs <1 indicate protective effects. For each social health measure, a series of 3 zero-inflated negative binomial models are presented (1-1 to 1-3 for social connectedness and 2-1 to 2-3 for perceived social support) predicting prospective current suicidal ideation presence and severity since the last assessment. The threshold for significance is set to p < .01. Both series of 3 models correspond to progressive model results with health-related risk factors entered second and interactions between health-related risk factors and social health measures entered last.
∗p < .05 (nominal effect), ∗∗p < .01 (significant effect), ∗∗∗p < .001 (significant effect).
OR, odds ratio; RR, rate ratio.
Social health measure corresponds to social connectedness in models 1-1 to 1-3 and to perceived social support in models 2-1 to 2-3.
