Intervention effect on self-reports
Each of the self-reports associated with emotional reactivity (positive affect score, negative affect score, Penn State worry questionnaire) showed improvement in the intervention and control groups from baseline to 16 weeks, but did not show meaningful between-group differences (all Cohen’s d < 0.3). Similarly, all self-reports associated with cognitive control showed improvement over time, with the rational problem-solving (1.43 [95%CI: −1.25, 4.1], Cohen’s d = 0.3) and impulsive/careless raw scores (−1.47, [95%CI: −3.57, 0.63], Cohen’s d = 0.4) having meaningful differences in improvement in the intervention group compared with the control (Table
