The Lifetime Prevalence, Risk Factors, and Co-Morbidities of Specific Phobia Among Pediatric Population: A Cross-Sectional National Survey

Background Specific phobia (SP) is one of the most common mental disorders among general population. In this national survey in Iran, we aimed to identify the lifetime prevalence, predictors, and co-morbidities of SP among children and adolescents. Methods A face-to-face household interview was applied by 250 skilled clinical psychologists using the Persian version of the kiddie schedule for affective disorders and schizophrenia for school-age children/present and lifetime version (K-SADS-PL) to determine the prevalence of SP and its co-morbid conditions. Results About 30 000 individuals participated in this study. We identified 923 individuals (378 boys and 545 girls) with SP. The lifetime prevalence rate of SP was 4.8%. This condition was related to gender, age, and type of settlement. Female gender and living in urban areas were the main positive predictors of developing SP. We showed that parental educations and their history of psychiatric hospitalization were not predictors of SP occurrence. Anxiety and behavioral disorders were the most common reported co-morbidities in our included children and adolescents. Conclusions The findings of this study indicate that SP is a prevalent disorder among pediatric population with different co-morbidities and should not be underestimated.
