This study aimed to develop and evaluate a new parent-report measure to assess primary schoolchildren’s academic behaviors in the home context. We developed the Academic Behavior Scale (ABS) and administered it to Chinese parents of primary schoolers along with other measures. Six hundred and forty-five parents and 170 primary schoolchildren in Grades 4–6 were recruited from a public primary school and completed a set of questionnaires. After that, the psychometric properties of the ABS including factorial validity, convergent and concurrent validity, as well as internal consistency were evaluated using confirmatory factor analysis and correlation analysis in Mplus v.8.3. The results confirmed a two-factor structure for the scale, with satisfactory convergent and concurrent validity and internal consistency. This study provides preliminary evidence for the satisfactory psychometric properties of the ABS among Chinese parents.
