A study of the validity and reliability of the parental homework support scale

We conduct a psychometric evaluation of the Parental Homework Support Scale (PHSS) involving 796 eighth-grade students. After randomly dividing the sample into two groups, we performed exploratory factor analysis (EFA) on Group 1 (n = 398) and confirmatory factor analysis (CFA) on Group 2 (n = 398). Findings revealed that the PHSS consisted of two distinct yet related subscales: Content-oriented Support and Autonomy-oriented Support. In addition, the current investigation found a satisfactory level of factor loading invariance across gender. Results further revealed that, consistent with theoretical expectations, the PHSS was positively correlated with value belief, expectancy belief, help seeking, homework management, homework completion, and math homework grade.
