Summary
This study validates the Italian Disgust Propensity and Sensitivity Scale-Revised (DPSS-R). Findings support a general disgust susceptibility factor and four specific factors, useful for clinical psychology.
Area of Science:
- Psychology
- Psychometrics
Background:
- The Disgust Propensity and Sensitivity Scale-Revised (DPSS-R) is a key tool for assessing disgust.
- Evaluating its Italian version is crucial for broader clinical and research applications.
Purpose of the Study:
- To assess the factor structure and psychometric properties of the Italian DPSS-R.
- To validate the scale in general population samples.
- To explore the underlying factor structure, including potential general and specific factors of disgust.
Main Methods:
- Two studies were conducted with a total of 578 participants from the general population.
- Exploratory and confirmatory factor analyses were used to evaluate the DPSS-R's structure.
- Graphical models were employed to visualize interrelationships with external scales.
Main Results:
- Exploratory factor analysis identified four factors: self-focused disgust, disgust propensity, somatic anxiety, and disgust sensitivity.
- Confirmatory factor analysis validated this structure and suggested a bifactor model with a general disgust susceptibility factor.
- Interrelationships between DPSS-R factors and scales for anxiety sensitivity and disgust were mapped.
Conclusions:
- The Italian DPSS-R demonstrates robust psychometric properties.
- A bifactor model provides a comprehensive understanding of disgust, with a general factor and specific sub-factors.
- These findings support the DPSS-R's utility in clinical settings for identifying psychopathological profiles related to disgust.

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:

01:29Reliability and Validity
14.2K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...
