Prévention et identification précoce des jeunes à haut risque dans les cliniques en milieu scolaire

A three-group stepped wedge design was proposed. During initial screening, we identified 128 individuals met inclusion criteria but only 39 individuals agreed to participate in the study. We randomized these 39 individuals into three cohorts for the stepped wedge design: cohort 1 (n=10), cohort 2 (n=15), and cohort 3 (n=14). Cohort 1 received 1 week of treatment as usual, then initiated the COPE2Thrive intervention. Cohort 2 received 2 weeks of treatment as usual, then initiated the COPE2Thrive intervention. Cohort 3 received 3 weeks of treatment as usual then initiated the COPE2Thrive intervention.

Cognitive Behavioral Therapy-based program to help teens deal with anxiety, stress and depression by showing them how to develop skills needed to stop negative thoughts and start thinking and behaving in more positive ways.

The control arm includes the same 39 youth randomized to Cohort 1, 2, or 3 during the time period before they were switched into the COPE2THRIVE intervention.

The control group receives usual care for youth at risk in the area of study.

The K-CAT-S is a computerized adaptive test for assessment of DSM 5 conditions in youth. Adaptive testing allows the assessment to be done in less than 10 minutes with high validity compared against diagnostic interviews. High scores indicate greater psychopathology. For each of six domains, the minimum score is 0, a score between 45-64 is moderate, a score greater than 65 is severe, and the maximum score is 100. For this primary outcome, the Total K-CAT was used, adding scores across all six domains for a range of 0-600. Change in the numeric level of these symptoms will be the primary outcome of the testing of the preliminary effectiveness of the COPE2Thrive intervention.

The Weiss Functional Impairment Scale Self Report (WFIRS-S) is an assessment of the student's perception of how emotional and behavior problems have impacted functional impairment over the past month, across six domains including family, school, life skills, child's self-concept, social activities, and risky activities. Higher mean item scores indicate greater functional impairment. The minimum mean item score is 0, the maximum mean item score is 3, and the ROC population cut-off is 0.65. A mean change score of 0.25 is the minimal clinical important difference.

We administered a single assessment of The Kiddie Computerized Adaptive Testing (K-CAT-P) to participants' parents at baseline to obtain collateral parent report of youth symptoms. The scoring metrics of this testing are identical to the Kiddie Computerized Adaptive Testing Student Report (K-CAT-S). The Kiddie Computerized Adaptive Testing Parent Report (K-CAT-P) screener provides a combined numeric score for each module based on validated quantitative comparisons. Higher scores indicate higher levels of symptoms. The minimum score for any module is 0, a numeric score between 45-64 for any module is considered moderate, a numeric score of 65 or above for any module is considered severe, and the maximum score for any module is 100. Scores for each of the six modules are reported.

We administered a single assessment of the Weiss Functional Impairment Scale Parent Report (WFIRS-P) to participants' parents at baseline to obtain collateral parent data. The Weiss Functional Impairment Scale Parent Report (WFIRS-P) is an assessment of the parent's perception of the child's functional impairment over the past month, across six domains including family, school learning and behavior, life skills, child's self-concept, social activities, and risky activities. Higher mean item scores indicate greater functional impairment. The minimum mean item score is 0, the maximum mean item score is 3, and the ROC population cut-off is 0.65. A mean change score of 0.25 is the minimal clinically important difference. Scores for each of the six domains are reported.
