Investigation the Psychometric Characteristics of the Resolved Scale of Manifest Anxiety in Children-Second Edition in Students

The aim of this study was to evaluate the psychometric characteristics of the revised scale of manifest anxiety in children-the second edition in the students' studies. The present study was applied in terms of purpose and descriptive in terms of sales. The statistical population of the study included all students studying between the ages of 15 and 17 in Ardabil city. According to the Cochran's formula, the optimal sample for this study was 290 people. Therefore, 300 people were selected as the sample. First, the English form was translated into Persian, then the translation was reversed, and in the first run, the ambiguous questions were removed, and finally the final scale was implemented. After collecting the data, confirmatory factor analysis method, Pearson correlation coefficient and Cronbach's retesting and alpha correlation method were used for analysis. The reliability coefficient of the scale was obtained by calculating Cronbach's alpha for the total scale of 0.87. Also, the results of Pearson correlation coefficients of the apparent anxiety variable with the four factors and the use of confirmatory factor analysis method confirmed the validity of the structure and all fitness indicators were in a favorable situation above 0.90. The results of this study, along with other foreign studies, indicate the optimal psychometric characteristics of this tool, so that this tool can be used in anxiety screening in schools and clinical trials.
