Questionnaire for the Assessment of Self‐Disgust: The psychometric testing among mental disorders in China

Abstract

Research on self-disgust is relevant to psychopathologic tendencies because it has been shown to play a critical role in several mental disorders. Examining self-disgust and exploring its role in mental health are significant goals. The purpose of this study was to translate the Questionnaire for the Assessment of Self-Disgust (QASD) into Chinese and evaluate its validity and reliability. The translation and validation of the QASD were guided by the World Health Organization's Process of Translation and Adaptation of Instruments. Three phases were undertaken: (a) professional translation and expert panel review, (b) pretesting, and (c) psychometric evaluation. The psychometric evaluation was tested among 1,068 patients who were recruited from two psychiatric hospitals and three psychological clinics of tertiary hospitals. In this study, multigroup confirmatory factor analysis (CFA) supported the two-factor structure of the original QASD construct. Measurement invariance showed that the QASD is invariant across the patients with heterogeneous mental health diagnoses. The correlation of QASD with the Self-Esteem Scale (SES) and the Trait Anger Scale (TAS) showed that it has good convergent validity and discriminative validity. Internal consistency and test-retest yielded acceptable results. Thus, the findings suggest that the Chinese version of the QASD is a reliable and valid instrument with adequate psychometric properties for assessment of self-disgust among patients with mental disorders in China.

Self‐disgust and stigma both mediate the relationship between stoma acceptance and stoma care self‐efficacy

“…Due to the lack of tools specifically for self‐disgust in patients with cancer, researchers used the self‐disgust scale (SDS; Overton, Markland, Taggart, Bagshaw, & Simpson, 2008) to measure the self‐disgust caused by cancer (Azlan et al., 2017a, 2017b). However, recent studies have shown that the newly developed QASD is more accurate than SDS in terms of factor construction, sample composition, and item settings (Ille et al., 2014; Jin, Li, Gutiénez‐Colón & Jiménez‐Herrera, 2020; Powell, Overton, & Simpson, 2014; Schienle et al., 2014). Therefore, we used the QASD and to ensure the patients refer the items to the situation of stoma, we specifically marked the instruction at the beginning of the questionnaire ‘please focus on the feeling under the stoma rather than other diseases’.…”

Self-disgust and the brain: Individual difference in behavioral self-disgust mediates the relationship between regional gray matter volume in the medial prefrontal cortex and anger rumination

“…Self-disgust can be regarded as a personality factor (Overton et al, 2008) and a specific self-concept (Jin, Li, et al, 2020;Powell et al, 2015). According to personality neuroscience (Kanayama et al, 2017;Morita et al, 2021) and the multiple aspects self-theory (Walla et al, 2021), the human self has a neurophysiological basis.…”

“…Physical self-disgust refers to a feeling of disgust in the self, reflecting a negative assessment and the feeling of enduring characteristics of oneself, while behavioral self-disgust represents a negative evaluation of and feeling regarding one's actions (Overton et al, 2008;Powell et al, 2016). To some degree, physical and behavioral self-disgust are mutually independent (Jin, Li, et al, 2020).…”
