^*Rates are shown with 95% confidence intervals (CIs) in parentheses. Individual p values and 95% CIs are not adjusted for multiple comparisons. The nominal or uncorrected p value corresponding to the Bonferroni bound for α = .05 is .05/12 = .0042. Depression screen-positive indicates current major depression or major depression in partial remission; depression screen-negative, history of past depression only or no history of depression.
