BackgroundSelf-harm entails high costs to individuals and society in terms of suicide risk, morbidity and healthcare expenditure. Repetition of self-harm confers yet higher risk of suicide and risk assessment of self-harm patients forms a key component of the health care management of self-harm patients. To date, there has been no systematic review published which synthesises the extensive evidence on risk factors for repetition.ObjectiveThis review is intended to identify risk factors for prospective repetition of self-harm after an index self-harm presentation, irrespective of suicidal intent.Data sourcesPubMed, PsychInfo and Scirus were used to search for relevant publications. We included cohort studies which examining factors associated with prospective repetition among those presenting with self-harm to emergency departments. Journal articles, abstracts, letters and theses in any language published up to June 2012 were considered. Studies were quality-assessed and synthesised in narrative form.ResultsA total of 129 studies, including 329,001 participants, met our inclusion criteria. Some factors were studied extensively and were found to have a consistent association with repetition. These included previous self-harm, personality disorder, hopelessness, history of psychiatric treatment, schizophrenia, alcohol abuse/dependence, drug abuse/dependence, and living alone. However, the sensitivity values of these measures varied greatly across studies. Psychological risk factors and protective factors have been relatively under-researched but show emerging associations with repetition. Composite risk scales tended to have high sensitivity but poor specificity.ConclusionsMany risk factors for repetition of self-harm match risk factors for initiation of self-harm, but the most consistent evidence for increased risk of repetition comes from long-standing psychosocial vulnerabilities, rather than characteristics of an index episode. The current review will enhance prediction of self-harm and assist in the efficient allocation of intervention resources.

Despite extensive research into the phenomenon of flow, there has been a comparative deficit in literature relating to the experience of shared or combined flow. This pilot study explored the subjective experience of combined flow in musical jam sessions, with particular emphasis on delineating the characteristics, outcomes, and practical applications unique to combined flow. In-depth semistructured interviews were held with six musicians who had extensive experience of group jam sessions. Grounded theory analysis of interview data identified two major themes; the experience of combined flow as a sequential progression through a set of stages; and the inter-subjectivity of the experience leading to the development of empathy between group members. A major finding was that the combined flow experience discussed by musicians met many of the criteria for classification as a flow experience, while also having the unique positive outcome of empathy development.

Different types of communication have a significant but small effect on (acute) pain. Positive suggestions and informational preparation seem to lower patients' pain. Communication interventions show a large variety in quality, complexity and methodological rigour; they often used multiple components and it remains unclear what the effective elements of communication are. Future research is warranted to identify the effective components.
