Abstract

Introduction: Many instruments for assessing general parenting have been reported as burdensome and are thus seldom used in studies exploring children's energy balance-related behaviors or weight. This study evaluates the factorial structure of the item-reduced version of the Comprehensive General Parenting Questionnaire (CGPQ), which assesses five constructs of general parenting.

Methods: The study uses data from two cross-sectional studies: Study 1 in 2014 (n = 173) and Study 2 in 2015-16 (n = 805). Parents of children aged three to six answered the CGPQ; in Study 1 the 69-item version, and in Study 2 the 29-item version. The reduction was based on the results of the confirmatory factor analyses (CFA) in Study 1. In both datasets, internal consistency, as Cronbach's alphas and intraclass correlations between the items of each construct, was tested. A combined assessment of the CFA and items response theory evaluated the construct validity and the item importance for the 29-item version, and a further the reduced 22-item version.

Results: In Study 1, the highest Cronbach's alphas were shown for the five constructs in the 69-item version. A higher intraclass correlation was found between the constructs in the 69- and 29-item versions, than between the 69- and the 22-item version. However, a high concordance was found between the constructs in the 29- and 22-item versions in both Study 1 and in Study 2 (0.76-1.00). Testing the goodness-of-fit of the CFA models revealed that the 22-item model fulfilled all the criteria, showing that it had a better factorial structure than the 29-item model. Standard estimations ranged from 0.20 to 0.76 in the 22-item version.

Conclusion: The reduced 22- and 29-item versions of the 69-item CGPQ showed good model fit, the 22-item version the better of the two. These short versions can be used to assess general parenting without overburdening the respondents.
