Three‐factor structure and psychometric properties of Witte's Risk Behaviour Diagnosis Scale: A French version adapted to diabetes

The aim of this study was to verify the psychometric properties and the factorial structure of Witte's Risk Behaviour Diagnosis (RBD). This article shows the results of a French version of the RBD adapted to diabetes screening. An exploratory factor analysis was carried out in order to understand the number of underlying factors, a confirmatory factor analysis was performed and the four‐factor model proposed by the author and alternative models were compared. The concurrent validity was tested by a correlational analysis with the Perceived Fear Emotions Scale. The results confirmed a stable factor structure for the 12‐item version, with three factors reflecting total efficacy, severity of and susceptibility to threat. The value of having a psychometrically valid instrument to assess the impact of fear appeal‐based campaigns is linked to the current lack of a comprehensive assessment tool and the importance of preventing health risk behaviours.
