- Abstract:
- BACKGROUND: Disgust is a fundamental emotion linked to survival, but its classification as a primary emotion remains debated. This study develops and validates a questionnaire assessing disgust as a primary emotion and examines its relationship with personality traits and psychopathology. METHODS: A total of 482 German speaking participants completed an online survey. The sample was split for a principal component analysis (N = 250) and confirmatory (N = 232) factor analyses. Correlations and hierarchical regressions tested associations with personality traits and psychiatric symptoms. RESULTS: Initial item reduction via PCA resulted in two alternative unidimensional models with eight and five Items. CFA confirmed excellent model fit for both versions (DISGUST-8: χ2 = 13.00, p = 0.88, df = 20, χ2/df = 0.65, RMSEA = 0.000 (90% CI: 0.000, 0.057), CFI = 1.000; NFI = 0.992, TLI = 1.006, SRMR = 0.042; DISGUST-5: χ2 = 0.893, p = 0.97, df = 5, χ2/df = 0.18, RMSEA = 0.000 (90% CI: 0.000, 0.092); CFI = 1.000; NFI = 0.999; TLI = 1.011; SRMR = 0.017). Internal consistency was high for both versions (DISGUST-8: α = 0.89; DISGUST-5: α = 0.88). Trait disgust correlated highest with neuroticism (rDISGUST-8 = 0.36; rDISGUST-5 = 0.36) and anxiety (rDISGUST-8 = 0.27; rDISGUST-5 = 0.28). Regression analysis confirmed disgust as a significant predictor of neuroticism (t(457) = 4.19, β = 0.12). DISCUSSION: The findings highlight disgust's role in personality and psychopathology. The developed scale reliably measures disgust, demonstrating its association with neuroticism. Future research should explore cross-cultural validation and refine the scale's clinical applicability.
