Web-based cognitive training for breast cancer survivors with cognitive complaints-a randomized controlled trial

Background

Cognitive complaints are common amongst breast cancer survivors, and no standard treatment exists. The present study evaluates whether web‐based cognitive training can alleviate subjectively reported and objectively assessed cognitive complaints in a sample of breast cancer survivors. The primary and secondary outcomes were an objective measure of working memory and a measure of perceived cognitive functioning. Additional outcomes were neuropsychological tests of memory, executive function, working memory and questionnaire‐based assessment of anxiety, depression and somatization.

Methods

A total of 157 female breast cancer survivors were recruited from an existing cohort and through announcements in open access cancer‐related Internet fora and randomly allocated to either web‐based cognitive training (eCogT) with telephone support (n = 94) or a waitlist control (WLC) condition (n = 63). eCogT encompassed 30 training sessions over 6 weeks. Neuropsychological assessments were undertaken over the telephone, and questionnaire data was collected online. Data was collected at baseline, post‐intervention and at 5‐month follow‐up.

Results

Mixed linear models revealed no statistically significant change in primary or secondary outcome at follow‐up in either group. Statistically significant improvements (p 0.040–0.043) were found in the eCogT group for verbal learning and on a working memory test.

Conclusions

Web‐based cognitive training did not result in improvements of the primary or secondary outcome. Improved performance was observed on verbal learning and working memory. These effects were observed at 5‐month follow‐up, indicating long‐term effects of training. The intervention may be applied in a clinical setting at low cost and without risk of adverse effects.© 2016 The Authors Psycho‐Oncology Published by John Wiley & Sons Ltd.

Social anxiety and emotion knowledge: a meta-analysis

It has been proposed that social anxiety is associated with poor emotion knowledge (EK), although studies have revealed mixed results. The aim of the present paper was to systematically investigate the association between EK and both non-clinical and clinical social anxiety by means of meta-analyses. Systematic, electronic database literature searches were performed, and meta-analyses were conducted on 43 included studies. Results showed that social anxiety was negatively associated with EK. The strongest association was found between clinical levels of social anxiety and the ability to understand one's own emotions (intrapersonal EK). Regarding interpersonal EK, a subgroup analysis showed that social anxiety was more strongly associated with a decreased ability to understand complex emotions than to recognize basic emotions. No differences were found between patients with social anxiety disorder (SAD) and patients with other anxiety disorders. Although a large between study heterogeneity and differing methodologies may prevent any firm conclusions from being reached, the results indicate that poor EK may play an important role in SAD, and that it could be beneficial to target EK in the treatment of SAD.

Treating first episode psychosis--the service users' perspective: a focus group evaluation

UK national guidance has prioritized developing specialist services for first episode psychosis. Such services are in the early stages of development and a definitive treatment model has yet to be established. The aim of this study was to explore service users' experiences of a first episode intervention designed along evidence-based 'best practice' guidelines and to establish specific elements seen as effective to help inform future service planning and provision. Twelve users of a specialist first episode service participated in focus groups. These were then analyzed using Interpretative Phenomenological Analysis, a specialized form of content analysis. Key elements identified by the service users included the 'human' approach as a key to the recovery process, being involved in treatment decisions, flexibility of appointments, high nurse to patient ratio, reduction in psychotic symptoms, increased confidence and independence and the provision of daily structure. To our knowledge, this is the first systematic qualitative evaluation of users' experience of a specialist first episode treatment intervention. Our findings indicate that adherence to best practice guidelines was appreciated. Regular focus groups provide a continuous audit cycle incorporating service improvements in line with government recommendations, centrally informed by the service users' and caregivers' perspective.

Effects of psychological interventions on systemic levels of inflammatory biomarkers in humans: A systematic review and meta-analysis

The purpose of the present investigation was to systematically review randomized controlled trials examining the effects of psychological interventions on inflammatory biomarkers in adult populations and to quantitatively analyze those effects by meta-analysis. Two researchers independently searched key electronic databases, selected eligible publications, extracted data, and evaluated methodological quality. Nineteen randomized controlled trials examining a total of 1510 participants were included. The overall combined effect size from pre to post psychological intervention on pro-inflammatory biomarker levels was statistically significant, showing an attenuating effect, although of a small magnitude (s' g = 0.15, p = .008, CI [0.04-0.26]). However, this effect was not maintained into the follow-up period (g < -0.01, p = .964, CI [-0.19-0.18]). Looking at the individual biomarkers assessed across studies, only C-reactive protein (CRP) was found to significantly decrease following psychological intervention. A number of moderation analyses were conducted, none of which reached statistical significance. However, the numerically largest - and significant - within-group effect size was obtained for the group of studies that had preselected participants based on elevated psychological distress (g = 0.29, p = .047). In conclusion, psychological interventions appear efficacious in reducing pro-inflammatory biomarker levels. Future studies are recommended to carefully select individuals based on inflammatory (e.g., the presence of low-grade inflammation) and/or psychological (e.g., psychological distress) criteria.

Clinical effectiveness in first-episode patients

Managing patients with first-episode schizophrenia is a challenging task for psychiatrists. Early diagnosis and effective intervention are vital to achieving long-term positive clinical outcomes among first-episode patients. Although these patients are the most responsive to treatment, they are also more susceptible to adverse events. The efficacy and improved tolerability associated with the newer atypical antipsychotics means that these drugs can be used successfully in the treatment and long-term management of schizophrenia from the onset of illness. However, as well as managing the symptoms of the disease, pharmacological treatments need to meet the broader requirements of clinical effectiveness that encompass all of the outcome domains associated with schizophrenia. This article will discuss available data on atypical antipsychotics in first-episode patients and present the primary results from the F1RST (Southwark first-onset psychosis) study, which examined the use of quetiapine for the first-line management of schizophrenia as part of a specialist episode psychosis service.

Embodied cognitive restructuring: The impact of posture and movement on changing dysfunctional attitudes

BACKGROUND AND OBJECTIVES

Previous theoretical and empirical work has pointed to the important role of the body in emotion generation and emotion regulation. In the present study, we wanted to investigate if the performance of certain body postures and movement could facilitate cognitive restructuring of dysfunctional cognitive attitudes more effectively than traditional, verbal-only methods.

METHODS

In total, 130 participants were randomized to one of two groups. One group was subjected to cognitive restructuring (i.e., restructure only group; CR-only), verbally exploring a dysfunctional attitude from a curious, strong, and courageous perspective. The other group received the same verbal instructions but in addition to this, was asked to perform different bodily exercises (i.e., motor-enhanced restructuring group; M-CR) supposed to enhance experience of the different perspectives from which cognitive restructuring was employed.

RESULTS

Results confirmed the primary hypothesis, showing that the M-CR-group showed a larger decline in belief in dysfunctional attitudes compared with the CR-only group (F = 4.2, p = 0.041, d = 0.25). No differences on secondary outcomes were observed between the two groups.

LIMITATIONS

Future research should explore the effects of motor-enhanced CR both more long-term (e.g., durability over weeks) and in clinical samples (e.g., anxiety and depression).

CONCLUSION

Should the findings be replicated in clinical samples, it is encouraging that simple bodily exercises can enhance the effect of one of the most central skills of cognitive therapy.
