Internal consistency and reliability of the Swiss-French translation of the venous leg ulcer self efficacy tool (VeLUSET)

Abstract

ObjectiveThis study was conducted to assess the psychometric properties of the translated and adapted Venous Leg Ulcer Self Efficacy Tool (VeLUSET) in the new cultural context.DesignValidation studySettingThree outpatient clinics in Western Switzerland.Participants32 consecutive persons with venous leg ulcers (VLU).Main outcome measuresTo determine the internal consistency and reliability of the VeLUSET for use in a Swiss-French speaking venous leg ulcer population.ResultsOverall, the Cronbach alpha for the VeLUSET-FR was 0.96 (95% CI 0.93 to 0.98) on test and retest. Lin’s concordance correlation coefficient of test and retest scores was 0.93 (95% CI 0.86 to 0.96).ConclusionThe results indicate that the VeLUSET-FR is a valid and reliable instrument for measuring self-efficacy among Swiss-French persons affected by a venous leg ulcer. Our findings show that the psychometric properties are similar to those of the original tool. Therefore, we suggest that the VeLUSET-FR can be effectively used for measuring self-efficacy in Swiss-French persons with VLU.
