BackgroundSocial networks are important for mental health outcomes as they can mobilise resources and help individuals to cope with social stressors. Individuals with psychosis may have specific difficulties in establishing and maintaining social relationships which impacts on their well-being and quality of life. There has been a growing interest in developing social network interventions for patients with psychotic disorders. A systematic literature review was conducted to investigate the size of social networks of patients with psychotic disorders, as well as their friendship networks.MethodsA systematic electronic search was carried out in MEDLINE, EMBASE and PsychINFO databases using a combination of search terms relating to ‘social network’, ‘friendship’ and ‘psychotic disorder’.ResultsThe search identified 23 relevant papers. Out of them, 20 reported patient social network size. Four papers reported the mean number of friends in addition to whole network size, while three further papers focused exclusively on the number of friends. Findings varied substantially across the studies, with a weighted mean size of 11.7 individuals for whole social networks and 3.4 individuals for friendship networks. On average, 43.1 % of the whole social network was composed of family members, while friends accounted for 26.5 %.ConclusionsStudies assessing whole social network size and friendship networks of people with psychosis are difficult to compare as different concepts and methods of assessment were applied. The extent of the overlap between different social roles assessed in the networks was not always clear. Greater conceptual and methodological clarity is needed in order to help the development of effective strategies to increase social resources of patients with psychosis.Electronic supplementary materialThe online version of this article (doi:10.1186/s13104-015-1528-7) contains supplementary material, which is available to authorized users.

Although coercive measures have always been part of the psychiatric armamentarium, the ethical dilemma between the use of a "therapeutic" coercion and the loss of patients' dignity is one of the major controversial issues in mental health research and practice. The aims of the present review are to explore the existing literature on predictors of use of coercive measures and to explore the relationship between coercive measures and patient outcome. A literature search was conducted using MEDLINE, PsychyINFO, Scopus, Web of Knowledge and the Cochrane Database. In all selected papers, references were cross-checked to identify other possible eligible papers. The use of coercive measures was predicted by patients' clinical and socio-demographic features, staff characteristics and ward-related factors. Coercive measures have only a limited impact on patients' clinical and social outcome. At the current level of knowledge, coercion is still a controversial issue in mental health practice. Only few studies with a solid methodology have been carried out. Large multicenter and rigorous studies, with long-term follow-ups, are highly needed.
