Aim 1: Top Problem Severity Ratings Change Across the UP-C/A

The average TPA severity rating reported by the child was 5.09 units (SD = 1.669) for the first session and 2.21 units (SD = 1.628) for the last session. Results of the paired samples t-test indicate that, on average, child TPA severity ratings significantly decreased by 2.87 units (t(132) = 16.29, p < .001). Similarly, the average TP rating for the parent was 5.73 units (SD = 1.552) for the first session and 2.79 units (SD = 1.872) for the last session. Results of the paired samples t-test indicates that parent TPA severity ratings significantly decreased by 2.94 units (t(132) = 15.81, p < .001) over the course of the UP-C/A (See Table 3).

Aim 2: Clinical Significance of Changes in the TPA

We next examined if this reduction in TPA severity was meaningful beyond statistical significance. Using the reliable change index, we found that 87.4% of the child reported TPA ratings and 88.3% of the parent reported TPA ratings had a reliable change. In other words, 87.4% of the change in the child reported top problems is psychometrically reliable. Similarly, 88.3% of the change reported by the parent on the TPA were reliable beyond statistical significance.

Aim 3: Clinical and Demographic Predictors of Top Problem Rate Change

Controlling for age, sex, ethnicity, Hispanic status, and number of sessions attended, ETR and pre-treatment depression, measured by the RCADS, significantly predicted change in TPA severity ratings for the child (B = 1.97, t(121) = 5.73, p < .001; B = 0.09, t(121) = 2.51, p = .014; respectively; Table 4). The number of sessions attended was not a significant predictor of average change in TPA severity rating for the child (B = 0.12, t(121) = 1.84, p = .068). A model including age, sex, ethnicity, Hispanic identity, number of attended sessions, ETR, and baseline symptom severity as predictors, explained approximately 26% of the variance in child-reported TPA severity change scores (R² = .256). Using the same model for the parent-reported TPA severity change, ETR was the only significant predictor (B = 1.53, t(121) = 4.14, p < .001). We ran an additional model to see if mid-treatment response (MTR) significantly predicted top problem change in parent and child. Controlling for age, sex, ethnicity, Hispanic identity, number of sessions attended, and pre-treatment symptom rating for anxiety and depression, we found MTR to be a significant predictor of both parent-and child-reported TPA severity change (B = 1.84, t(121) = 5.43, p < .001; B = 2.19, t(121) = 6.93, p < .001; respectively; Table 5).
