Abstract

There is a lack of valid and reliable measures of determinants of sustainability specific to public health interventions in the elementary school setting. This study aimed to adapt and evaluate the Program Sustainability Assessment Tool (PSAT) for use in this setting. An expert reference group adapted the PSAT to ensure face validity. Elementary school teachers participating in a multi-component implementation intervention to increase their scheduling of physical activity completed the adapted PSAT. Structural validity was assessed via confirmatory factor analysis. Convergent validity was assessed using linear mixed regression evaluating the associations between scheduling of physical activity and adapted PSAT scores. Cronbach’s alpha was used to evaluate internal consistency and intracluster correlation coefficients for interrater reliability. Floor and ceiling effects were also evaluated. Following adaptation and psychometric evaluation, the final measure contained 26 items. Domain Cronbach’s alpha ranged from 0.77 to 0.92. Only one domain illustrated acceptable interrater reliability. Evidence for structural validity was mixed and was lacking for convergent validity. There were no floor and ceiling effects. Efforts to adapt and validate the PSAT for the elementary school setting were mixed. Future work to develop and improve measures specific to public health program sustainment that are relevant and psychometrically robust for elementary school settings are needed.
