Introduction

Disgust propensity (DP) and disgust sensitivity (DS) contribute to individual differences in the experience of disgust. Studies have shown that DP and DS are predictive of some anxiety (e.g., spider phobia and blood-injection-injury phobia) and obsessive-compulsive and related disorders.

Aim

The aim of this study was to develop and validate a Portuguese version of the Disgust Propensity and Sensitivity Scale-Revised (DPSS-R; van Overveld= et al., 2006) for use in Portuguese-speaking populations.

Method

Two hundred and six participants (162 females), with ages between 18 and 47 (M = 25.92; SD = 8.75), filled in the DPSS-R, which was first translated and adapted into Portuguese language by individuals highly proficient in English and then back-translated by a bilingual with no prior knowledge of the scale. Finally, the DPSS-R was subjected to a think-aloud procedure.

Results

The results showed good internal consistency (Cronbach's alfa = .833) for a DPSS-R. The two subscales displayed an adequate internal consistency (DPCronbach's alfa = .776; DSCronbach's alfa = .790). Test-retest analysis documented good intraclass correlation coefficient for the two subscales (ICCPropensity = .889; ICC Sensitivity = .900). We also confirmed the bifactorial structure using a confirmatory factor analysis, since we obtained appropriate values in all goodness of fit indices (χ2df = 1,906; CFI = .94; PCFI = .736; GFI = .93; PGFI = .607; RMSEA = .067).

Conclusion

DPSS-R obtained good psychometric properties and may therefore be proposed as a valid instrument to assess DS and DP in the Portuguese population. This instrument may provide an important contribute to study the development and maintenance of psychopathology associated with disgust.
