Data were collected using the SPQ and the Par-ticipation and Environment Measure for Children and Youth (PEM-CY). Test–retest and interrater reliability were assessed using intraclass correlation coefficients (ICCs). Internal consistency was assessed with Cronbach’s alpha. Concurrent and convergent validity were explored via correlations with the PEM-CY. Further psychometrics were examined using a Rasch model.RESULTS One hundred and eighty-seven children (136 [72.7%] male; mean age 9y [range 5y 6mo–12y 10mo, SD 2y]) were assessed by 67 teachers. Cronbach’s alpha, test–retest, and interrater reliability were acceptable–excellent across each SPQ scale (alphas=0.89, 0.9, 0.94, 0.79; test–retest ICCs=0.64, 0.61, 0.78, 0.62; interrater ICCs=0.85, 0.71, 0.90, 0.81). Concurrent and convergent validity were confirmed with significant positive correlations between SPQ and PEM-CY. After Mokken and Rasch model analysis, person and item reliability were good, and unidimensionality was con-firmed. Mean administration time was 8.2 minutes.INTERPRETATION The results suggest that the SPQ is a rapid, reliable, and valid tool for assessment of participation-related indicators in schools.847-854enThis is the peer reviewed version of the following article: Maciver, D., Tyagi, V., Johnston, L., Kramer, J.M., Richmond, J., Todorova, L., Romero-Ayuso, D., Nakamura-Thomas, H., Van Hartingsveldt, M. and O’Hare, A.
