Notes: GAF – The Global Assessment of Functioning; LIFE - The Longitudinal Interval Follow-up Evaluation

Current and past diagnoses included MDD, PTSD, panic, anxiety disorders, OCD, and eating disorders. Personality traits included: neuroticism, extraversion, conscientiousness, agreeableness, and openness to experience.

Percentage R² denotes the proportion of the total variance explained by the predictor added. P-value denotes significant ΔR² at p<.05.
