Social support scale scores, both log-transformed and unadjusted, presented as mean (standard deviation). Group comparisons were only performed on the log-transformed data as the unadjusted data were not normally distributed; these comparisons used two-tailed, pooled t-tests, or with the Satterthwaite t-test for unequal variances.
