Comparison of experiences of stress and coping between young people at risk of psychosis and a non-clinical cohort.

BACKGROUND: Although the experience of stress and associated coping responses are thought to play a role in the onset of schizophrenia and other psychotic disorders, there is little empirical evidence to support such a relationship. The relatively recent development of validated and reliable criteria for identifying young people at "ultra" high-risk (UHR) of psychosis has enabled the process of illness onset to be studied more closely than was previously possible. METHOD: This longitudinal study compared the experiences of stress and coping between a UHR cohort (N=143) and a healthy comparison group (HC group, N=32). RESULTS: The UHR group experienced significantly fewer life events over a 12-month period than the HC group, but there was no difference in the experience of minor events or "hassles". However, the UHR group reported feeling significantly more distressed by events, felt they coped more poorly and utilized different coping strategies. CONCLUSIONS: The appraisals made about stressors differentiated the groups and was associated with differences in coping and distress levels. This suggests that treatment strategies focusing on stress management and enhancing coping skills might be important components of preventive interventions.

Stress and psychosis: towards the development of new models of investigation.

The experience of stress is commonly implicated in the onset and maintenance of psychotic disorders such as schizophrenia. Previous studies that have addressed this relationship have had mixed results and serious methodological flaws associated with study design are common. One central limitation is the over-reliance on the experience of life events as a measure of the experience of stress. Research in the general stress literature suggest that attention also needs to be paid to the experience of other types of stressful events (such as 'hassles') as well as qualitative appraisals of events to fully understand the relationship between stressful experiences and mental health problems such as psychosis. Investigation of the experiences of stress by young people who are identified as being at heightened risk of developing a psychotic disorder would also result in a more complete understanding of the relationship between the experience of stress and the onset of psychotic disorder.

Strategies used by psychotic individuals to cope with life stress and symptoms of illness: a systematic review.

Psychological models of schizophrenia and other psychotic disorders suggest that poor coping responses to life stressors and to symptoms of illness is central to their development and maintenance and influences recovery. These models are widely accepted and inform psychological treatments for psychotic disorders. In this paper, 85 studies that explore how individuals with established psychotic disorders cope with symptoms associated with their illness, and with independent life events and stressors are comprehensively reviewed. Reviewed research included cross-sectional and longitudinal investigations of self-initiated coping. Despite limitations in the existing research, it is concluded that most individuals experiencing psychosis implement at least one strategy to cope with symptoms, and life events and most implement more than one strategy. It appears that having a repertoire of strategies to employ leads to greater effectiveness than simply relying on one strategy. This suggests that treatment strategies that aim to enhance the coping of individuals with psychosis should emphasize the development of a range of coping strategies. It also seems that there is no one coping strategy that is universally effective and situational, or other factors may influence both the choice of coping strategy implemented and its efficacy.

Early intervention for acute back injury: can we finally develop an evidence-based approach?

OBJECTIVE: Several reviews of the treatment of acute low back pain have been published in the past and have formed the basis of clinical guidelines. However, these lack consistency in some areas and valid data in others. As the literature in this field has continued to expand, the present review was undertaken to establish whether the guidelines in current use are supported by more recently published, scientifically rigorous research, and whether additional consensus regarding treatment of acute low back injury has been forthcoming in recent years. DESIGN: A review, and critical analysis, of literature relating to the treatment of acute low back pain that has been published since the production of the currently used clinical guidelines. The guidelines have been reviewed to assess whether their recommendations remain supportable. CONCLUSIONS: Recent research appears to support current clinical guidelines, i.e. exercise may have a positive effect while bed rest is ineffective and may be harmful, simple analgesics and nonsteroidal anti-inflammatory drugs (NSAIDs) have short-term benefits, and spinal manipulation may be effective in the first four weeks; no evidence was found for traction or back schools. However, we need more randomized controlled trials of treatments shown to be successful with the chronic population, e.g. focused on understanding psychological determinants, and using a multidisciplinary biopsychosocial approach. In the future this may help us to prevent acute low back progressing to the chronic state.
