Evaluation of the Psychometric Properties of the Persian Version of Spence Children's Anxiety Scale in Iranian Adolescents.

The Spence Children's Anxiety Scale (SCAS) is a tool for measuring anxiety symptoms in children and adolescents. In this study, the psychometric properties of the Persian version of SCAS were investigated in an Iranian adolescents. This study was conducted on a sample of 684 adolescents. For standardization of SCAS, first- and second-order confirmatory factor analyses wereperformed. Also, to evaluate convergent and divergent validity, Fornell and Larcker criteria (1994), along with the Revised Children's Manifest Anxiety Scale (RCMAS)and Children's Depression Inventory (CDI), was used. A receiver operating characteristic (ROC) curve analysis was also performedto determine the cut-off point. The model fit of the correlated six-factor model was good however, a second-order model provided a statistically superior fit to the data. The reliability coefficients for the total scale and its dimensions were satisfactory (α > 0.7). Therefore, it can be concluded that the Persian version of SCAS has acceptable reliability and validity and can be used as a useful tool for early screening of anxiety in Iranian adolescents due to its easy use and specific design for children and adolescents.

Investigation of the psychometric properties of children's somatization inventory in Iranian adolescents.

BACKGROUND: This study aimed to investigate the psychometric properties of children's somatization inventory (CSI-24) in a sample of Iranian school adolescents. MATERIALS AND METHODS: In this study, after translating and back-translating CSI-24, comparisons were made with the original version. The study population consisted of 394 school adolescents. Cronbach's alpha method was used to examine the reliability of the scale. Furthermore, the correlation of the scale with the Symptom Checklist-90-Revised was evaluated to determine its criterion validity, using Pearson's correlation coefficient. Exploratory and confirmatory factor analysis methods were applied for construct validity. RESULTS: Investigation of the psychometric properties of the Iranian version of CSI-24 showed its high reliability and confirmatory factor analysis results show the model's satisfactory fitting. CONCLUSION: The Persian version of CSI-24 is a useful self-report tool for evaluating the physical complaints of Iranian school adolescents aged between 12 and 18 years.
