The psychometric properties of the CFSS-DS for schoolchildren in Saudi Arabia: A confirmatory factor analytic approach

Abstract

Aim: To test the psychometric properties of an Arabic version of the Child Fear Survey Schedule-Dental Subscale (CFSS-DS) a using confirmatory factor analysis. Methods: Two convenience samples were obtained: Sample [1]: 600 boys (33%) and girls attending 4 public schools in Onizah and Sample [2] 800 girls attending 8 public schools in Buridah. The questionnaire asked the participant's age, gender, and completion of the CFSS-DS. The data were subjected to exploratory factor analysis (EFA), parallel factor analysis, Cronbach's alpha, confirmatory factor analysis (CFA), and goodness of fit statistics. Results: A total of 513 children in Sample [1] and 503 children in Sample [2] participated giving a valid response rate of 86% and 67%, respectively. From the EFA, 3 factors were identified and confirmed statistically using parallel factor analysis. The internal consistency of the 3 factors, Dental Fear Subscale (0.86), Hospital Fear Subscale (0.77), and Stranger Fear Subscale (0.71), was good. The CFA showed that the current EFA model was an equivalent fit to the El Housseiny et al (BMC Oral Health 2016;16:49). model; however, the solution using El Housseiny et al's structure was distorted. Conclusions: A 3-factor structure with acceptable reliability exists for this Arabic version of the CFSS-DS, confirmed by a CFA using an additional data set.
