  1. Due to non-independence of data and to obtain a global estimate of couple functioning, mean scores across all available parents were used for these analyses when there was more than one parent in a family [number of single-parent families = 11 (7 BD)]
  2. T-scores were used for the Personality and Coping Skills subcategories, *p < .05, ** p < .01
  3. BD: bipolar disorder; PD: personality disorder; ✔: significant group difference
