A network cross-cultural validation of the Parenting Sense of Competence Scale between Aboriginal and Torres Strait Islander and non-Aboriginal and Torres Strait Islander Australians

Abstract

Purpose

The Parenting Sense of Competence Scale (PSOC) is the most used instrument worldwide to measure parenting sense of competence. Considering that cultural differences influence parenting practices, an investigation of cross-cultural validity was required to ensure that PSOC scores can be compared between Aboriginal and Torres Strait Islander and non-Aboriginal and Torres Strait Islander Australians. To address this research gap, this study employed network psychometrics to investigate the cross-cultural validity of the PSOC between Aboriginal and Torres Strait Islander and non-Aboriginal and Torres Strait Islander Australians.

Methods

The study investigated the network psychometric properties of the PSOC instrument, specifically: (1) model estimation; (2) item redundancy; (3) dimensionality; (4) measurement invariance; (5) model fit; (6) criterion validity; and (7) reliability. The network model that was used was the Gaussian graphical model estimated with the graphical least absolute shrinkage and selection operator. Dimensionality was evaluated with exploratory graph analysis. Measurement invariance was evaluated via permutation testing. Data were from the South Australian Aboriginal Birth Cohort (n=178) and eMums study (n=107).

Main findings

The findings indicated that, after accounting for item redundancy, a revised 14-item version of the PSOC displayed the two theoretical dimensions of Efficacy and Satisfaction and was cross-culturally valid among Aboriginal and non-Aboriginal Australians.

Principal conclusions

The revised 14-item PSOC displayed excellent psychometric properties and is readily available to be used in Australia.
