Social cognition and metacognition in social anxiety: A systematic review.

Cognitive-behavioural and metacognitive approaches to emotional disorder implicate beliefs in social anxiety, but the types of beliefs differ across these perspectives. Cognitive models suggest that social beliefs about the self (i.e., high standards and conditional and unconditional beliefs) are central. In contrast, the metacognitive model gives centre stage to metacognitive beliefs (i.e., positive and negative beliefs about thinking) as main contributors to the maintenance of the disorder. Despite an expanding research interest in this area, the evidence for such contributions has not yet been reviewed. This study set out to systematically review relevant cross-sectional, longitudinal, and experimental investigations of the direct and indirect (through cognitive processes, such as anticipatory processing, self-focused attention, the post-mortem, and avoidance) relationships of social and metacognitive beliefs with social anxiety. Clinical and nonclinical samples were included, and correlation and regression coefficients as well as results from group comparisons (e.g., t tests and analyses of variance) were extracted. Overall, 23 papers were located, through PsycINFO, PubMed, and Web of Science, and reviewed using narrative synthesis. The results showed a robust positive relationship between social beliefs and social anxiety that appeared to be mediated by cognitive processes. Specific metacognitive beliefs were found to positively contribute to social anxiety both directly and indirectly, through cognitive processes. The study's findings are limited to 2 models of social anxiety and other minor limitations (e.g., grey literature was excluded). With these accounted for, the results are discussed in terms of the conceptualization and treatment of social anxiety and suggestions for future research are made.

Personality variables are associated with colorectal cancer patients' quality of life independent of psychological distress and disease severity.

OBJECTIVE: The aim of the present study was to test whether psychological distress and personality variables are independently associated with health-related quality of life (HRQOL) in colorectal cancer patients, after adjusting for age, gender, education and disease severity. METHODS: In a cross-sectional study of 162 colorectal cancer patients (response rate 65.6%), the following self-report instruments were administered: the Symptom Distress Checklist-90-R, the Sense of Coherence scale, the Life Style Index and the Hostility and Direction of Hostility Questionnaire. The outcome measures were the four components of the WHO Quality of Life Instrument, Short Form. We used hierarchical regressions to determine whether psychological distress mediates the relationship of personality and disease parameters with HRQOL. RESULTS: The overall proportion of the variance in the four components of HRQOL explained by our regression models ranged from 28.1 to 44.4%. Psychological distress was an independent correlate of HRQOL, associated with physical (p<0005), mental (p<0.05) and social relationships HRQOL (p<0.02). Personality variables were associated with HRQOL independent of psychological distress and disease severity. Sense of coherence and denial defense were positively associated with all aspects of HRQOL independent of psychological distress and disease parameters (p-values ranging from p<0.05 to p<0.0005). Hostility (p<0.01) and repression defense (p=0.024) were also independently but negatively associated with physical HRQOL. CONCLUSIONS: In colorectal cancer patients, psychological distress is associated with HRQOL independent of disease parameters but personality variables are also associated with HRQOL independent of disease severity and psychological distress, and this could be relevant to psychological interventions.
