ABSTRACT
Introduction: The Highly Sensitive Person Scale based on the sensory-processing sensitivity is a self-assessment questionnaire consisting of 27 items. The scale is designed in order to identify individuals with high sensitivity. Objective: The objective was to develop a French version of the scale. We tested its internal consistency and test-retest reliability on a French population sample. Another aim of this study was also to question the multidimensionality of the scale, for which several different models are suggested within the literature. Method: After translation and back-translation, a validation study was conducted on 814 adults. They were invited to complete an online questionnaire during the lockdown implemented due to COVID 19, between March 31st and May 11th (2020). Results: The internal reliability of the French version of HSPS was very good, with a Cronbach's alpha of. 90, as was that of the factors. Correlations between factors were significant (p < .001). The intra-class correlation (ICC) for test-retest was. 889 (0.874–0.903;95% confidence interval). Factor analyses suggested a 4-factors structure, mixing the models found in the literature. Conclusions: This study focused on a French adaptation of the HSPS scale. The results showed good psychometric qualities and stayed true to the original HSPS scale. The scale could be useful both to practitioners in their clinical practice and to researchers in fundamental research. © 2022 Elsevier Masson SAS
