Abstract

Objective: The purpose of this study was to explore VALIDITY and RELIABILITY of the short form of Persian Picture Vocabulary Scale (PPVS) adopted from the British Picture Vocabulary Scale (BPVS).Method: The study was carried out in two stages. In the first stage, 100 children (half female) randomly selected from 4771 pre-school students from the city of Qom, underwent the preliminary version of PPVS.Results: Relevant analysis to identify the difficulty level and discriminate power of the items revealed inappropriate items. These items were substituted by other items taken from the long form of (BPVS). The statistical properties of the PPVS were tested on 410 students (198 female) selected from the population using a quota sampling based on sex and age distribution in each educational borough. Chronbach alpha (=0.59) confirmed an acceptable RELIABILITY for of the PPVS. Differentiate VALIDITY of test was established using t-test analyses applied on the mean scores of different ages. The content VALIDITY of test was also qualified based on expert opinions.Conclusion: The finding revealed an acceptable VALIDITY and RELIABILITY for the short form of the PPVS. This would suggest that the PPVS can be considered as a valuable test for educational and clinical purposes.
