  1. Although mean values for outcomes, predictors, and covariates are reported in the table by age, regression analyses included age as a continuous measure rather than categorical. We combined ages 17 and 18 into one group because there was only 1 participant who was 18 years old. Similarly, we combined ages 11 and 12 into one group because there were 11 participants who were 11 years old
  2. LoPF-Q Levels of personality functioning questionnaire, NRI Network of relationships inventory, closeness Positive relationship qualities, discord Negative relationship qualities
