  1. a Mental distress was measured with the Global Score Index (GSI) of the Symptoms Checklist (SCL-90-R). Changes in mental distress were computed by subtracting the GSI determined at follow-up from the GSI determined at admission; a ‘positive score change’ refers to an improvement in mental distress
  2. b Unstandardized beta coefficient with 95% Confidence Interval (CI) and R2 = 0.1, derived from a multiple linear regression with simultaneous entry of variables (the "enter" method)
