Version arabe du questionnaire diabetes attitude scale-3: fiabilité, validité et données normatives

Abstract

The aim of this study was to translate and analyze the psychometric properties of the third version of the Arabic Diabetes Attitude Scale. A methodological study of psychometric validation of the scale according to the guidelines of Vallerand cross-cultural validation was conducted. Type 1 and type 2 diabetics, aged 18 and over, without cognitive impairment or altered mental status were recruited on a convenience-sampling basis. An Arabic-language self-administrated developed questionnaire including diabetics' demographic and clinical data and the experimental third version of the Diabetes Attitude Scale was used. All Vallerand cross-cultural validation steps were completed except for convergent validity and confirmatory analysis. A sample of 333 diabetics was recruited. Reliability and validity of the experimental version of the scale were satisfactory. Correlations between test and retest dimensions were close to 1, and overall Cronbach's alpha coefficient of the experimental version was 0.769. The content validity index was 0.82 proving the accuracy of the concept measurements by the scale. Principal components analysis, by orthogonal Varimax rotation, produced nine factors. Correlation coefficients between the five dimensions of the theoretical model of the scale ranged from 0.002 to 0.367, confirming that each dimension measured a single content. The third version of the Arabic Diabetes Attitude Scale has been proven valid and reliable. It is ready for use in clinical practice.
