Supplementary Materials for: Identifying children with self-regulation problems: factorial structure and psychometric properties of the QUVA-p, a screening tool for preschool teachers.

The Preschool Self-Regulation Questionnaire (Questionario di Valutazione dell’Autoregolazione [QUVA-p]) is a teacher-completed screening tool for assessing child dysregulation at preschool age. This study presents the psychometric properties of the questionnaire, which was investigated in a sample of 413 preschoolers. We tested for construct validity, measurement invariance across gender, subscale internal consistency, subscale convergent validity with executive control tasks (working memory, inhibitory control, and cognitive flexibility), and power to detect child differences in executive control. Results show that the factorial structure of the QUVA-p is in line with Nigg’s theoretical model of self-regulation and the subscales have good reliability. Measurement invariance is maintained across gender; the instrument reveals small but significant associations with executive control tasks, and it could be useful to detect child differences in executive control. In ESM 1 we provided a detailed description of the demographic characteristics of the participants and tests used. Specifically, we described the QUVA-p questionnaire (development; content; validation process) and the Executive Control tasks that were administered to a sample of 413 preschoolers. In ESM 2 we provided results of additional analyses on the measurement invariance of the questionnaire across sex of participants and on the power of the questionnaire to capture differences in executive control between children screened as at-risk and not-at-risk of dysregulation.
