Objective: This study seeks to validate and standardize the extended version of the knowledge of parenting strategies scale (KOPSS) among Iranian citizens. Methods: This paper is a descriptive measure validation study, which falls in the category of quantitative research. The statistical population consisted of Iranian parents with children aged 3-12, living together. Thirty parents were selected through convenience sampling and were tested using the Persian KOPSS in order to estimate the standard deviation of the total KOPSS score and obtain the sample size for validation and standardization (n=725). Then, thirty parents were studied at an interval of three weeks to calculate the test-retest reliability. Furthermore, 330 other parents were selected through convenience sampling to measure internal consistency reliability and concurrent criterion validity. To calculate concurrent criterion validity, the Persian KOPSS scores were correlated with the scores of Robinson’s Parenting Styles and Dimensions Questionnaire (PSDQ). To obtain the standardized scores and percentile ranks of the raw Persian KOPSS scores, an online survey was conducted on 725 eligible parents (including 532 mothers and 193 fathers). Results: The correlation of the total Persian KOPSS-20 score with the PSDQ sub-scales was found to be larger than 0.40 (0.417-0.508). The standardized KOPSS-20 was obtained by converting the raw scores into normed z and T-scores and calculating the percentile ranks of the entire group (n=725). Conclusion: KOPSS-20 was found to yield reproducible and reliable results with satisfactory validity coefficients.
