Results support the presence of the positive illusory bias also in the domain of everyday life activities. Improvement of self-evaluation of competencies should become a focus of treatment.
Abstract. Recently, Garfinkel and Critchley (2013) proposed to distinguish between three facets of interoception: interoceptive sensibility, interoceptive accuracy, and interoceptive awareness. This pilot study investigated how these facets interrelate to each other and whether interoceptive awareness is related to the metacognitive awareness of memory performance. A sample of 24 healthy students completed a heartbeat perception task (HPT) and a memory task. Judgments of confidence were requested for each task. Participants filled in questionnaires assessing interoceptive sensibility, depression, anxiety, and socio-demographic characteristics. The three facets of interoception were found to be uncorrelated and interoceptive awareness was not related to metacognitive awareness of memory performance. Whereas memory performance was significantly related to metamemory awareness, interoceptive accuracy (HPT) and interoceptive awareness were not correlated. Results suggest that future research on interoception should assess all facets of interoception in order to capture the multifaceted quality of the construct.
BackgroundInteroceptive deficits have been found to be associated with suicidal ideation and behavior. However, an objective measure of interoceptive accuracy has not been investigated in participants with suicide ideation, by now. This study aimed at investigating interoceptive accuracy and sensibility in persons with and without suicide ideation (SI) while controlling for severity of depressive symptoms.MethodNinety-five participants (age: M = 34.8, SD = 11.6, n = 56 female [58.9%]; n = 51 patients with a Major Depressive Disorder and n = 44 healthy participants) were assessed for interoceptive accuracy and sensibility, depression and SI.ResultsTwenty-five participants (26%) reported SI. They showed interoceptive accuracy comparable to persons without SI (t = −.81, p = .422), but significantly lower interoceptive sensibility. After controlling for severity of depressive symptoms in a hierarchical linear regression analysis, most associations between interoceptive sensibility and SI disappeared.ConclusionResults suggest that suicide ideators do not lack the ability to perceive their own bodily signals but they feel less able to use them in a way that is advantageous for them. Differences between suicide ideators and non-ideators appear to be largely driven by depressive symptoms (depression bias).
Background: The Expanded Prostate Cancer Index Composite questionnaire is widely used as a comprehensive assessment of health-related quality of life issues in prostate cancer management, distinguishing urinary, bowel, sexual, hormonal domains. The primary purpose of this study was to assess the factor structure of this questionnaire. Patients and Methods: A principal component analysis with orthogonal (varimax) rotation was conducted on data collected from 418 patients after primary (external beam radiotherapy and permanent iodine-125 brachytherapy) and postoperative radiotherapy for prostate cancer. Results: Health-related quality of life scores well demonstrated differences in subpopulations before radiotherapy and different toxicity profiles of specific radiotherapy concepts. The extraction of 12 factors accounted for 75.5% of the variance. With exception of the sexual domain, a strong dependence between the function in a domain and the related bother was found. The concept to discriminate urinary incontinence and urinary irritation/ obstruction subscales was supported. However, the items ‘bleeding with urination’ and ‘bloody stools’ have loaded on separate factors. After separation of the items of the function and bother subscales, a 4-factor solution was confirmed to be optimal, respectively. Conclusion: The obtained factor structure corresponds to the original Expanded Prostate Cancer Index Composite subscales. Minor divergences have been found, depicting especially items concerning ‘incontinence’ and ‘bleeding’ as distinct aspects of a domain.
Older individuals who recognize their cognitive difficulties are more likely to adjust their everyday life to their actual cognitive functioning, particularly when they are able to estimate their abilities accurately. We assessed self- and spouse-ratings of memory and attention difficulties in everyday life of healthy, older individuals and compared them with the respective test performance. Eighty-four older individuals (women's age, M = 67.4 years, SD = 5.2; men's age, M = 68.5 years, SD = 4.9) completed both the self and the spouse versions of the Attention Deficit Questionnaire and the Everyday Memory Questionnaire and completed two neuropsychological tests. Using the residual score approach, subjective metacognitive measures of memory and attention were created and compared with actual test performance. Significant associations between subjective and objective scores were found only for men and only for episodic memory measures. Men who underreported memory difficulties performed more poorly; men who overreported memory difficulties performed better. Men's recognition performance was best predicted by subjective measures (R² = .25), followed by delayed recall (R² = .14) and forgetting rate (R² = .13). The results indicate gender-specific differences in metacognitive accuracy and predictive validity of subjective ratings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
