Group means on neuropsychiatric questionnaires. We show 95% confidence intervals of effect sizes as Cohen’s d, which can be interpreted as follows: 0.2 as small, 0.5 as medium, and 0.8 as large [54]. Means and standard deviations for each group are presented, as well as the mean and SD for each measure to aid in interpretation. We derived SRS T-scores using the updated SRS-2 norms for all participants, regardless of the version the participant completed. We averaged CASI-4R raw item scores on similar subscales into composites instead of using T-scores because we encountered a strong ceiling effect when using CASI-4R T-scores because CASI-4R norms collapse all high raw scores into a T-score of 70. Thus, population-normed means and standard deviations are not available for comparison for these averaged composites. For example, all items from the dysthymia subscale and major depression subscales were averaged into a “Depression” composite, after accounting for the number of items in each subscale so that both scales were weighted equally in the composite. The composites are interpreted as “3” indicating that on average, the parent endorsed symptoms in the domain as occurring “very often,” 2 as “often,” 1 as “sometimes,” and 0 as “never”
