Baseline Study Participant Characteristics by Observation Time Point
MAY
Abbreviations: CMHC, community mental health center; GHQ, General Health Questionnaire; GP, general practitioner; SDQ, Strengths and Difficulties Questionnaire.Randomization was balanced on these GP characteristics.A total of 1170 eligible child-parent pairs were approached from May 2018 through February 2019, when the sample size for SDQ positive children was achieved; 619 of those eligible saw intervention GPs and 551 control GPs. Of these, 1111 provided consent and were screened (589 in the intervention group and 522 in the control group [95% for both groups]). One patient seeing an intervention GP could not be screened because of incomplete data; 4 parents seeing control GPs initially consented but declined screening; 1106 parents (588 seeing intervention GPs and 518 seeing control GPs) completed the SDQ screening. A total of 216 children (37%) seeing intervention GPs and 173 (33%) seeing control GPs screened positive (total, 389). Intervention GPs ultimately had from 1 to 20 screen-positive children and control GPs from 2 to 15 (Child participants seeing intervention and control GPs were similar. The children’s mean (SD) age was 8.9 (2.9) years (range, 5-15 years), 182 (47%) were female patients, and their mean (SD) SDQ total problems score was 20.2 (3.9; range, 15-31) (
