No research, to date, has directly investigated the role of metacognition in self-critical rumination and low self-esteem. The aims of this study are: to investigate the presence of metacognitive beliefs about self-critical rumination; the goal of self-critical rumination and its stop signal; and the degree of detachment from intrusive self-critical thoughts. Ten individuals reporting both a self-acknowledged tendency to judge themselves critically and having low self-esteem were assessed using metacognitive profiling, a semi-structured interview. All participants endorsed both positive and negative metacognitive beliefs about self-critical rumination. Positive metacognitive beliefs concerned the usefulness of self-critical rumination as a means of improving cognitive performance and enhancing motivation. Negative metacognitive beliefs concerned the uncontrollability of self-critical rumination and its negative impact on mood, motivation and perception of self-worth. The primary goal of engaging in self-critical rumination was to achieve a better or clearer understanding of a given trigger situation or to feel more motivated to resolve it. However, only four participants were able to identify when this goal had been achieved, which was if the trigger situation were not to occur again. Participants unanimously stated that they were either unable to detach from their self-critical thoughts or could do so some of the time with varying degrees of success. More often than not, though, self-critical thoughts were viewed as facts, would rarely be seen as distorted or biased, and could take hours or days to dissipate. These findings provide preliminary evidence that specific facets of metacognition play a role in the escalation and perseveration of self-critical rumination.  相似文献

Objective: More evidence from prospective studies is needed to determine ‘if’ and ‘how’ social cognitive constructs mediate behaviour change. In a longitudinal study, we aimed to examine potential social cognitive mediators of objectively measured physical activity (PA) behaviour among people with type 2 diabetes (T2D) who participated in a six-month PA intervention. Methods: All participants from the proven effective Healthy Eating and Active Living for Diabetes in Primary Care Networks trial were included for this secondary analysis. Change in pedometer-derived daily step counts (baseline to six months) was the outcome of interest. Primary constructs of interest were from Social Cognitive Theory, however constructs from and Theory of Planned Behaviour were also tested in a mediating variable framework using a product-of-coefficients test. Results: The sample (N = 198) had a mean age of 59.5 (SD 8.3) years, haemoglobin A1c 6.8% (SD 1.1), 50% women, BMI 33.6 kg/m2 (SD 6.5), systolic pressure 125.6 mmHg (SD 16.2) and average daily steps were 5879 (SD 3130). Daily pedometer-determined steps increased for the intervention group compared to usual care control at six-months (1481 [SD 2631] vs. 336 [SD 2712]; adjusted p = .002). There was a significant action theory test effect for ‘planning’ (A = .21, SE = .10, p = .037), and significant conceptual theory test results for ‘subjective norms’ (B = 657, SE = 312, p = .037) and ‘cons’ (B = ?664, SE = 270, p = .015). None of the constructs satisfied the criteria for mediation. Conclusions: We were unable to account for the effect of a pedometer-based PA intervention for people with T2D through our examination of mediators. Our findings are inconsistent with some literature concerning PA interventions in diabetes; this may be due to variability in measures used or in study populations.  相似文献

Publication ethics is an important aspect of both the research and publication enterprises. It is particularly important in the field of biomedical science because published data may directly affect human health. In this article, we examine publication ethics policies in biomedical journals published in Central and Eastern Europe. We were interested in possible differences between East European countries that are members of the European Union (Eastern EU) and South-East European countries (South-East Europe) that are not members of the European Union. The most common ethical issues addressed by all journals in the region were redundant publication, peer review process, and copyright or licensing details. Image manipulation, editors’ conflicts of interest and registration of clinical trials were the least common ethical policies. Three aspects were significantly more common in journals published outside the EU: statements on the endorsement of international editorial standards, contributorship policy, and image manipulation. On the other hand, copyright or licensing information were more prevalent in journals published in the Eastern EU. The existence of significant differences among biomedical journals’ ethical policies calls for further research and active measures to harmonize policies across journals.  相似文献

Research is presented on the attributional gender bias: the tendency to generate different attributions (explanations) for female versus male students’ performance in math. Whereas boys’ successes in math are attributed to ability, girls’ successes are attributed to effort; conversely, boys’ failures in math are attributed to a lack of effort and girls’ failures to a lack of ability. This bias has been shown in previous research to be committed by teachers, parents, and students themselves. The present work sought to investigate whether this bias among secondary school math teachers might be reduced over time through adoption of an incremental theory of intelligence. Findings revealed at baseline, teachers committed the expected bias in reference to their high-achieving students’ math performance. Following exposure to stimuli, teachers in both experimental and control conditions reduced this bias. Unexpectedly, teachers across conditions showed a type of compensation for the bias by reversing stereotypical attributions for girls’ and boys’ successes and failures in math. Further, participants relapsed to the original bias nearly a year later. Findings indicate the potential to modify attributional gender bias, but also the challenges for achieving long-term changes within school contexts and for emphasizing effort beyond ability in math performance.  相似文献

Termination of pregnancy for fetal abnormality (TOPFA) is a potentially traumatic event that may lead to intense grief symptomatology. The present study included 41 couples who were assessed 1–6 months after TOPFA. No gender differences were found regarding the intensity of trauma symptomatology or the prevalence of clinically relevant trauma symptomatology, present in about a third of the sample. Most couples were congruent regarding trauma symptomatology. Women experienced guilt with significantly more frequency than men. For both genders, guilt influenced both trauma and grief symptomatology. For women only, guilt influenced grief symptomatology indirectly, through trauma symptomatology. Clinical implications are discussed.  相似文献

Can a mere gesture lead to intimate product bonding? In this research, we find that affectionate gestures (e.g. hugging, stroking) can serve as routes to object attachment. We suggest that the mere execution of an affectionate gesture can generate emotional attachment, which translates into enhanced product attitudes. However, this effect is contingent on the existence of facilitating conditions via the presence of humanlike characteristics in the target object of the affectionate gesture.  相似文献

The association between global functionality and religiosity among patients from developing and predominantly Catholic countries warrants attention. To compare religiosity and psychosocial functioning in Mexican schizophrenia patients with and without a history of religious delusions, seventy-four patients with paranoid schizophrenia were recruited. Patients with a history of religious delusions had more psychiatric hospitalizations and poorer psychosocial functioning compared with those without a history of religious delusions. No differences emerged between groups in the total scores of religiosity scales. A history of religious delusions rather than religiosity itself may have an influence on psychosocial functioning among Mexican patients with schizophrenia.  相似文献
