“…However, there was also a significant impact of 6‐month self‐disgust on 12‐month dysfunctional attitudes, suggesting that perhaps a bidirectional relationship in which self‐disgust, once established, functioned to perpetuate cognitive biases. Two studies (Azlan, Overton, Simpson, & Powell, ; Powell, Azlan, Simpson, & Overton, ), that examined the predictive role of self‐disgust on the development of depression in the context of a (disgust‐related) physical health stressor leant further tentative support to the conceptualization of self‐disgust as a contributor to the aetiology of mood difficulties. Powell et al (), in their cross‐sectional examination of the role of self‐disgust in the development of depression in cancer patients, found that self‐disgust mediated the relationship between disgust‐related cancer side effects and depressive symptomatology in patients high in disgust sensitivity but not in patients low in disgust sensitivity, with both physical and behavioural self‐disgust exhibiting significant direct effects on depression.…”

This systematic literature review examined the clinical utility of the construct of self‐disgust in understanding mental distress. Specifically, the review assessed whether there is a shared conceptual definition of self‐disgust, the face and construct validity of the quantitative assessment measures of self‐disgust, and the predictive validity of self‐disgust in formulating the development of a range of psychological difficulties. A systematic database search supplemented by manual searches of references and citations identified 31 relevant papers (27 quantitative, 3 qualitative, and 1 mixed). Analysis of qualitative papers indicated a number of shared features in the definition of self‐disgust, including a visceral sense of self‐elicited nausea accompanied by social withdrawal and attempts at cleansing or suppressing aspects of the self. Quantitative assessment measures appeared to capture these dimensions and evidenced good psychometric properties, although some measures may have only partially captured the full self‐disgust construct. Strong relationships were observed between self‐disgust and a range of mental health presentations, in particular, depression, body‐image difficulties, and trauma‐related difficulties. However, these relationships are smaller when the effects of other negative self‐referential emotions were controlled, and stronger conclusions about the predictive validity of self‐disgust are limited by the cross‐sectional nature of many of the studies.

“…Due to the behavioural consequences of cancer and its treatment that may elicit disgust (e.g., incontinence, vomiting), and the positive correlation with physical SD, we also expected to observe the same pattern in behavioural SD (Powell et al, 2016).…”

“…Symptoms of anxiety and depression have been shown to have a stronger relationship with DS and SD than DP (Powell et al, 2016), and so we expected the former traits to have the stronger association. Given the nature of the eliciting stimuli (i.e., cancer and its side-effects), we made a directional prediction that the disgust traits in people with cancer would have a larger relationship with symptoms of depression and anxiety than the same relationships in controls.…”

“…The reduction of disgust through habituation usually displays some degree of domain specificity (e.g., Rozin, 2008) and it would be interesting in a future study to assess differences in cancer using measures that tap into disgust subtypes (e.g., the Disgust Scale- Olatunji et al, 2007). Our own recent work suggests that 'core' disgust elicitors (conceptualised by Rozin et al, 2008, as related to food/eating and body waste products) are likely to be particularly problematic for people with cancer (Powell et al, 2016).…”

“…For example, cancer patients often have difficulty focusing attention away from the disease, tend to ruminate on it (e.g., Bishop & Warr, 2003;Chan, Ho, Tedeschi, & Leung, 2011) and have cancer-related negative intrusive thoughts (e.g., Brenne, Loge, Kaasa, Heitzer, Knudsen, & Wasteson, 2013;Walker, Nail, Larsen, Magill, & Schwartz, 1996). Thus, we expect that changes engendered by cancer and its treatment -that are disgust-provoking (Powell, Azlan, Simpson, & Overton, 2016) and germane to the diagnosis -may result in disgust reactions having a stronger influence on current psychological wellbeing in people with cancer (vs. cancer-free controls). Few studies, however, have examined the prediction of disgust responses on the psychological wellbeing of individuals with cancer, and those that have had a restricted focus on disgust proneness in colorectal cancer scenarios only (e.g., Reynolds et al, 2013;Reynolds et al, 2014;Smith, Lowenstein, Rozin, Sherriff, & Ubel, 2007).…”

Objectives: Evidence suggests that disgust responses, known to negatively affect psychological wellbeing, may differ in people with cancer. We performed the first quantitative investigation of three discrete types of disgust trait -disgust propensity, sensitivity, and self-directed disgust -in people diagnosed with a broad range of cancers (versus cancer-free controls), and explored their associations with psychological wellbeing. Design:In a cross-sectional survey design, 107 participants with heterogeneous cancer diagnoses, recruited from cancer charities and support groups, were matched with cancer-free controls by age and gender.Outcome measures: Measures of the three disgust traits were taken alongside measures of anxiety and depression.Results: Disgust sensitivity and physical self-disgust were significantly higher in the cancer than control sample, while disgust propensity and behavioural self-disgust were lower. The disgust traits had a different pattern of associations to psychological wellbeing across the two groups, with disgust sensitivity predicting depressive symptoms to a significantly greater extent in the cancer than control group.

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.
