Overall weighted average from random effects model
Study sample sizes indicated were deleted from the calculation of the Total N due to overlap.
ES=Effect Size; S/O=Sexual Orientation; Gender of participants in included effect sizes: M=Male, F=Female, C=Combined in original study; S/O Definition: 0=Unknown, 1=Identity, 2=Attraction, 3=Behavior, 4=2 or more; Comments: 1=Excluded Bisexuals; 2=Controlled for covariates; 3=Public data set; 4=Non-school-based sample; 5=Excluded some effect size estimates in meta-analysis due to within-study redundancy; 6=International sample; 7=Examined longitudinal patterns of depression outcomes; 8=Examined mediators of the association between sexual orientation and the outcomes; 9=Examined moderators of the association between sexual orientation and the outcomes; 10=Effect sizes were calculated and published in original study; 11=Effect sizes were calculated using summary statistics for each subgroup provided by the original study (e.g., average scores for each group or prevalence rates for each group).
