A study of factorial structure of the persian version of the multidimensional peer-victimization scale in primary schools students in Semnan city

Abstract

Introduction: The victimization of children in schools is one of the most controversial issues in the area of education around the world. Therefore, the purpose of this study was to examine the psychometric properties of multidimensional peer-victimization scale in students. Materials and Methods: In this study, 607 students in Semnan were selected by using a stratified sampling method and responded to multidimensional peer-victimization scale, Illinois bullying scale and Harter’s motivation questionnaire (concurrent validity). For data analysis, we used factor analysis method, Cronbach;#39s alpha coefficients and Pearson correlations. Results: The nucleotide changes c135G>A/A45A (rs1800858) in exon 2 and c.337+9G>A (rs2435351) and c.337+137G>T (rs2505530) were found in intronic region of RET gene. Among patients and relatives, the most and least genotype and allele frequencies were c.337+137G>T (rs2505530) and c135G>A/A45A (rs1800858), respectively. Also we did not find any significant correlation between detected nucleotide changes and disease phenotype, gender and ethnicity. Conclusion: Results indicated that multidimensional peer-victimization scale in the Persian version questionnaire has acceptable psychometric properties for school students, and it can be used as a valid instrument in psychological research.
