Prevalence of sexual violence victimisation amongst mental health service users
Researchers from King’s College London, Anjuli Kaul, Laura Connell-Jones, Sharli Anne Paphitis and Sian Oram (VISION researcher), have published a systematic review and meta-analyses in Social Psychiatry and Psychiatric Epidemiology which provides up-to-date estimates on the prevalence and risk of sexual violence victimisation amongst mental health service users.
This review pooled data from 26 studies encompassing a total of 197,194 participants. Sexual violence included any sexual acts, comments or advances (or attempts at said behaviours) made towards a person without their consent. Mental health service users included any person who had been in contact with a psychiatric inpatient, outpatient, community, perinatal, liaison, addiction, veteran psychiatric inpatient, or forensic mental health service.
The researchers searched 3 electronic databases (Medline, Embase, and PsychINFO) for peer-reviewed publications from their dates of inception until 18th July 2022. There were no restrictions on the geographic location of the included studies.
Key findings
The review found that studies consistently showed a high prevalence of past year and adult lifetime (since the age of 16) sexual violence victimisation in psychiatric service users, with higher rates found in women than men. Additionally, both male and female psychiatric service users were found to have an increased risk of experiencing sexual violence compared to non-psychiatric service users. This was the case regardless of whether the study measured past year or adult lifetime sexual violence or sampled a population of inpatients, outpatients or both.
The meta-analyses revealed high levels of heterogeneity within the data, which was likely partly due to the varied instruments used across studies to measure mental health and sexual violence. Additionally, there was not enough data available to calculate the pooled odds ratio of sexual violence victimisation for male or female psychiatric service users, nor was it possible to adjust odds ratios for known confounders such as age, ethnicity, income level or substance abuse.
The findings emphasise the need for healthcare practitioners to effectively recognise and respond to sexual violence in mental health services, and the need for a comprehensive and consistent measurement framework for sexual violence to enable reliable and comparable prevalence data to be collected.
