Implementation of OSCE test to develop appropriate tool to measure mothers' parenting skills.INTRODUCTION
 In this study, mothers' parenting skills were measured by the OSCE test.  The results of Explanatory Factor Analysis showed that nine stations of OSCE were focused on two factors.  The designed OSCE test has the suitable psychometric features to be used by researchers to assess mothers' parenting skills.

Implementation of OSCE test to develop appropriate tool to measure mothers' parenting skills.INTRODUCTION
 In this study, mothers' parenting skills were measured by the OSCE test.  The designed OSCE test has the suitable psychometric features to be used by researchers to assess mothers' parenting skills.
OSCE test
The reliability of the test was determined with three methods including split half, Cronbach alpha, and correlation between assessors' scores in two similar stations.  The total Cronbach alpha coefficient obtained was 0.83 which indicated that the test had a high internal reliability. 
Cronbach alpha
The Spearman correlation coefficient obtained for two halves of the test was 0.76. 
Spearman correlation coefficient
The construct validity of the test was determined with Explanatory Factor Analysis.


 The results of Explanatory Factor Analysis showed that nine stations of OSCE were focused on two factors.
