Severity, symptomatology, and treatment duration for mental health disorders: a retrospective analysis from a conflict-affected region of northern Nigeria

Abstract

BackgroundMental Health and psychosocial support (MHPSS) programs are essential during humanitarian crises and in conflict settings, like Nigeria’s Borno State. However, research on how types of traumatic stress and symptom severity affect clinical improvement is lacking in these contexts, as is consensus over how long these patients must engage in mental health care to see results.MethodsRecords from 11,709 patients from the MHPSS program in Pulka and Gwoza local government areas in Borno State, Nigeria from 2018 and 2019 were retrospectively analyzed. Patient information, symptoms, stress type, severity (CGI-S scale), and clinical improvement (CGI-I and MHGS scales) were assessed by the patient and counselor. Associations between variables were investigated using logistic regression models.ResultsClinical improvement increased with consultation frequency (OR: 2.5, p < 0.001 for CGI-I; OR: 2, p < 0.001 for MHGS), with patients who received three to six counseling sessions were most likely to improve, according to severity. Survivors of sexual violence, torture, and other conflict/violence-related stressors were nearly 20 times as likely to have posttraumatic stress disorder (PTSD) (OR: 19.7, p < 0.001), and depression (OR: 19.3, p < 0.001) symptomatology. Children exposed to conflict-related violence were also almost 40 times as likely to have PTSD (OR: 38.2, p = 0.002). Most patients presented an improvement in outcome at discharge, per both counselors (92%, CGI-I) and self-rating scores (73%, MHGS).ConclusionWe demonstrate a threshold at which patients were most likely to improve (3 sessions for mild or moderate patients; 6 sessions for severe). In addition, we identify the specific types of stress and symptom severity that affected the number of sessions needed to achieve successful outcomes, and highlight that some stress types (especially torture or having a relative killed) were specifically linked to PTSD and depression. Therefore, we emphasize the importance of classifying patient stress type and severity to identify the appropriate duration of care needed.
