Five-year outcomes in a randomised controlled trial of prolonged exposure therapy and supportive counselling for post-traumatic stress disorder in adolescents: a task-shifted intervention.

BACKGROUND: Cognitive-behavioural therapies with a trauma focus are effective in reducing posttraumatic stress disorder and other psychological distress in adolescents. Long-term follow-up data on adolescents treated for PTSD remain scarce, with few studies extending beyond 12 months after treatment completion. OBJECTIVE: To evaluate the maintenance of treatment gains in a comparative study of effectiveness of PE-A and SC up to 60 months post-treatment. METHOD: Sixty-three adolescents diagnosed with PTSD were randomly assigned to either treatment, provided by newly trained and supervised non-specialist health workers. The primary outcome measure was PTSD symptom severity, as independently assessed on the Child PTSD Symptom Scale (CPSS). We report on the 60-month post-treatment follow-up, building on post-treatment, 3-month, 6-month, 12-month and 24-month post-treatment data that have been published previously. RESULTS: Participants in both treatment groups maintained a significant reduction in PTSD symptoms up to 60-months post-treatment (F (7, 343) = 2.86, p < .01). Participants receiving prolonged exposure experienced greater improvement on the CPSS at all follow-up assessment timepoints, except for the 60-month FU (p = .28; g = 0.33). CONCLUSION: Adolescents with PTSD continued to maintain treatment gains up to 60-months post-treatment. These data, along with findings from the original RCT, indicate that a brief treatment protocol (averaging 9 sessions of PE-A or SC) in a LMIC, task-shifted to be delivered by nurses without prior psychotherapy experience, led to lasting improvements in PTSD and comorbid symptoms for up to five years. The sustained benefits and improved functioning over the first few years post-treatment support expanding both treatments, especially PE-A, in community settings.

Perspectives on play for young children with disabilities in South Africa: a qualitative study.

PURPOSE: All children have the right to play. Children with disabilities are often excluded from play activities. We aimed to explore caregivers', older community members', and key stakeholders' perceptions and experiences of play as influenced by socio-cultural, institutional, and public policy factors. These insights informed the early stages of intervention development. MATERIALS AND METHODS: In-depth semi-structured interviews (n = 23) were conducted with caregivers of children with disabilities aged 2-5 years, older community members, and key stakeholders who had experience working with children with disabilities. Data were thematically analysed, following a socio-ecological approach. RESULTS: Four themes emerged: (i) making play doable and affordable, (ii) play away the challenges, (iii) playing together or not, and (iv) play opportunities. The results highlighted how intrapersonal and interpersonal factors and experiences shaped perspectives of play and play-based interventions for children with disabilities. CONCLUSIONS: Our findings emphasise the importance of a community-informed approach in grounding the early stages of intervention development, which may help to ensure that a future play-based intervention is contextually appropriate.

Improving access to antipsychotic medications for schizophrenia in Ethiopia, Nigeria, Rwanda, and South Africa: an evidence-based global consensus.

There are disparities in access to antipsychotics for schizophrenia across different country settings. Improving access to a wider and more equitable range of medications in low-income and middle-income countries is a priority. A multidisciplinary team of international experts, including individuals with lived experience, appraised the most relevant and recent information on antipsychotics in schizophrenia and contextualised it to four African countries (Ethiopia, Nigeria, Rwanda, and South Africa) using a validated consensus methodology. We recommended a list of drugs to prioritise to guide clinical implementation and research, and market shaping. We identified key evidence gaps: little of the existing evidence comes from the countries of interest, trials generally involve highly selected populations, and the complexity of real-world settings is not reflected. However, this methodology highlights a route forward to prioritise the best available evidence on pharmacological treatments for schizophrenia at a global scale, which could also be applied to treatments for other mental health conditions.

A whole-brain voxel-based analysis of structural abnormalities in PTSD: An ENIGMA-PGC study.

BACKGROUND: Patients with posttraumatic stress disorder (PTSD) exhibit smaller regional brain volumes in commonly reported regions including the amygdala and hippocampus, regions associated with fear and memory processing. In the current study, we have conducted a voxel-based morphometry (VBM) meta-analysis using whole-brain statistical maps with neuroimaging data from the ENIGMA-PGC PTSD working group. METHODS: T1-weighted structural neuroimaging scans from 36 cohorts (PTSD n = 1309; controls n = 2198) were processed using a standardized VBM pipeline (ENIGMA-VBM tool). We meta-analyzed the resulting statistical maps for voxel-wise differences in gray matter (GM) and white matter (WM) volumes between PTSD patients and controls, performed subgroup analyses considering the trauma exposure of the controls, and examined associations between regional brain volumes and clinical variables including PTSD (CAPS-4/5, PCL-5) and depression severity (BDI-II, PHQ-9). RESULTS: PTSD patients exhibited smaller GM volumes across the frontal and temporal lobes, and cerebellum, with the most significant effect in the left cerebellum (Hedges' g = 0.22, pcorrected = .001), and smaller cerebellar WM volume (peak Hedges' g = 0.14, pcorrected = .008). We observed similar regional differences when comparing patients to trauma-exposed controls, suggesting these structural abnormalities may be specific to PTSD. Regression analyses revealed PTSD severity was negatively associated with GM volumes within the cerebellum (p corrected  = .003), while depression severity was negatively associated with GM volumes within the cerebellum and superior frontal gyrus in patients (p corrected  = .001). CONCLUSIONS: PTSD patients exhibited widespread, regional differences in brain volumes where greater regional deficits appeared to reflect more severe symptoms. Our findings add to the growing literature implicating the cerebellum in PTSD psychopathology.
