Key mental health differences in conflict-related sexual violence and how sex, severity, and early intervention impact on improvement: a retrospective observational study

Abstract

Abstract Background Conflict-related sexual violence (CRSV) is a significant health and human rights issue in humanitarian contexts, but there is a need of further research on differences between sexes in terms of severity of symptoms and improvement. Consequently, we explored the differences in severity and outcomes among male and female survivors of CRSV who received mental health and psychosocial support (MHPSS) in an armed conflict setting. Methods We retrospectively analysed medical records from 3442 CRSV survivors in a MHPSS programme in Borno State, Nigeria, between 2018 and 2019. Patient characteristics, severity (measured with Clinical Global Impression of Severity Scale [CGI-S scale]), and improvement (measured with Clinical Global Impression of improvement [CGI-I] scale) were assessed by an attending counsellor. We assessed predictors for severity and improvement using a multivariable logistic regression analysis and time to improvement by sex using Kaplan Meier (K–M) curves and Cox regression. Results We included 3442 patients who had at least one CRSV event in this study (2955 [85.9%] female, 486 [14.1%] male, one unknown). The most prevalent categories of symptoms were depression (49.9%; n = 1716), post-traumatic (25.6%; n = 879), and anxiety (20.3%; n = 697) symptoms. Most patients had mild (59.0%; n = 1869/3170) or moderate (36.4%; n = 1153/3170) symptoms at baseline, with 4.7% having severe symptoms (n = 148/3170). The logistic regression analysis (n = 1106), showed male patients had a 59% higher odds of severe symptoms at baseline than female patients (aOR 1.59; 95% CI 1.04–2.45). Among males, those older than 55 years had three times higher odds of presenting severe symptoms than younger patients (aOR 3.65; 95% CI 1.43–9.34). Women aged 36–55 years were more likely to present improvement than younger female patients (aOR 1.32; 95% CI 1.11–1.58). For both sexes, prompt attention after a CRSV event (≤ 3 days) positively predicted improvement (aOR 13.9; 95% CI 1.48–130 males, aOR 2.11; 95% CI 1.22–3.64 females) compared to late attention. Time to improvement did not differ between sexes, with an average of at least three consultations needed to achieve improvement. Conclusions Our study suggests that psychological attention of survivors within the first 72 h should be a priority. MHPSS programmes addressing CRSV should be inclusive to all patients, and gender-neutral approaches to ensure access, safety, confidentiality, and non-discrimination for all survivors should be developed.
