Construct validity and responsiveness of the Persian version of Extended Version of the Knowledge of Parenting Strategies Scale

The Persian version of Extended Version of the Knowledge of Parenting Strategies Scale is a tool with appropriate reliability and validity that has been translated and validated in 2022.

The present study was performed on a sample of 330 parents (207 mothers and 123 fathers) with the aim of determining the structural validity of this scale. Also, in order to determine the responsiveness of Persian version of KOPSS scores to positive parenting program, a purposive sampling was performed from 15 parents (9 mothers and 6 fathers) in an elementary school. In the form of pre-test and post-test design, a group of these parents was first pre-tested and then the training course was held in the form of five two-hours online sessions. Three weeks after the end of the course, the post-test was performed.

The correlation coefficient between the pre-test and post-test scores of the participants was r = 0.892 (P<0.001). After removing two items, the standardized Cronbach's alpha coefficient for the Persian version of KOPSS was calculated to be 0.717. In confirmatory factor analysis, another 11 items were deleted due to poor factor loading. In the final model of KOPSS-20, the indexes of fit were all acceptable. Univariate analysis of covariance revealed that KOPSS-20 is able to respond to the Positive parenting program and the effect size of this difference is at a high level.

The present study showed that KOPSS-20 is a tool with the adequate structural validity and is sensitive and responsive to the effects of intervention and parenting education.
