Descriptive statistics of the self-report symptom measures between attentive and C/IE participants. Skew: the empirical skewness of the distribution of total symptom scores. Total score: the average symptom score across attentive and C/IE participants. Scores were compared using a two-sample t-test (df = 384, α = 0.05, two-tailed, not corrected for multiple comparisons). Cronbach’s α: a measure of response consistency, where values closer to 1 indicate greater consistency in responses. % Clinical Cutoff: the percentage of participants reaching threshold for clinical symptomology before and after screening based on the infrequency measure. The BIS/BAS scales do not have clinical thresholds.
