Background: A broad variety of different functions can underlie acts of Non-suicidal self-injury (NSSI). Whilst research so far has identified many of the commonly reported functions, no reliable estimates of prevalence currently exist for these different NSSI functions. Understanding the prevalence of NSSI functions represents a key to better understanding the phenomenology of NSSI and addressing the differing needs of the NSSI population. We conducted a systematic review and meta-analysis of the prevalence of NSSI functions in community and clinical samples., Method: A literature search of electronic databases PsycINFO, Medline, and Web of Science from date of inception to March 2017 was undertaken. A pre-specified framework for categorising different functions of NSSI was used to collate data from across studies. A random-effects meta-analysis of prevalence was then undertaken on these data., Results: Intrapersonal functions (66-81%), and especially those concerning emotion regulation were most commonly reported by individuals who engage in NSSI (63-78%). Interpersonal functions (e.g., expressing distress) were less common (33-56%)., Limitations: The review was limited to English-language articles. Reviewed articles were inconsistent in their measurement of NSSI. Inconsistency within pooled prevalence estimates was high when moderators were not accounted for., Conclusions: Findings indicate that intrapersonal functions of NSSI are most common and are present for the majority of participants. This finding supports dominant emotion-regulation models of NSSI, and the use of interventions that work to improve emotion-regulation ability. However, interpersonal functions remain endorsed by a substantial portion of participants., (Copyright © 2017 The Authors. Published by Elsevier B.V. All rights reserved.)

This audit aimed to evaluate the utility of the Initial Assessment Tool (IAT) in documenting routine sensitive enquiry of adult interpersonal trauma within three Community Mental Health Teams (CMHTs) in North-East Glasgow. In addition, it sought to evaluate if disclosures informed patient risk assessments and if patients were signposted to additional support services. 57% of 90 IATs had evidence of routine sensitive enquiry. Of 51 casefiles with evidence of routine sensitive enquiry, 61% had evidence of the information informing their risk assessments and 14% had documented recommendations of support organisations. The IAT appeared able to assist clinicians with routine sensitive enquiry in adulthood. However, there may be advantage in supporting staff understanding of how to ask questions to specific populations and to use this information to inform treatment planning. Given the prevalence of adult interpersonal trauma experienced by patients presenting to CMHTs, trauma-informed approaches to care should be implemented. [ABSTRACT FROM AUTHOR]
