Note. γ (SE) = unstandardized fixed effects with standard errors in parentheses. R_β² = semi-partial R². 95% CI = 95% confidence intervals. Time: 0 = baseline, 1 = 6 months (FU1), 2 = 1 year (FU2), 3 = 1.5 years (FU3), 4 = 2 years (FU4), 5 = 2.5 years (FU5), 6 = 3 years (FU6), 7 = 3.5 years, and 11 = 5.5 years (FU10). Gender: 0 = Male, 1 = Female. Race: 0 = White, 1 = Black.

Borderline Personality Disorder includes relevant symptoms without the affective instability items. ICC = intra-class correlation coefficient.
