Intergenerational Risk and Resilience of Rohingya in Displacement

The iRRRd study is an ongoing prospective longitudinal prenatal birth cohort study based in Cox's Bazar, Bangladesh. Between February 2023 and March 2024, 2,888 pregnant women were enrolled (approximately 80% Rohingya refugees living in camps, 20% Bangladeshi host community). The study aims to investigate (1) the effects of being conceived, gestated, born, and raised in contexts of conflict and forced displacement on child health and development; (2) the mechanisms underlying the intergenerational transmission of conflict and displacement trauma to offspring; and (3) the sources of heterogeneity in these associations across individual, social, biological, and contextual risk and protective factors. Five waves of data collection have been completed: prenatal recruitment (Wave 1), third-trimester follow-up for a subset of the sample (Wave 2), birth (Wave 3), 28 days postpartum (Wave 4), and 6 months postpartum (Wave 5, completed April 2025; N=2,526). This registration covers Wave 6, the 36-month follow-up, in which target children are assessed when they reach 36 months of age. Anticipated enrollment for this wave is approximately 2,200 mother-child dyads. Waves 1-5 were conducted without preregistration due to logistical and timing constraints inherent to launching large-scale research in a complex humanitarian context. Design and preparation for the 36-month wave began in June-July 2025, and field piloting of study procedures and measures began in September 2025. Follow-ups with children reaching 36 months of age began in late May 2026. The original planning estimate of March 2026 reflected the 36-month mark for the earliest-born children in the cohort (first births occurred in March 2023); the ±2-month eligibility window (Part 5) accommodated the modest delay to actual fieldwork start. Up to the first week of August, fieldwork progressed slowly with a smaller number of enumerators, as several measures were still being refined and modified based on ongoing piloting. We consider this wave officially launched once onboarding and training of an expanded group of data collectors is complete and the pace of follow-ups picks up with number of children turning 36 months of age. All field activities that predate this registration are considered piloting and have served to iron out remaining logistical, technical, and language issues, and to finalize decisions on tool and item selection. No data have been analyzed, with the exception of measures for which psychometric properties needed to be examined to inform modification and selection decisions.

Study on the Prevention of Recidivism and the Consequences of Sexual Violence Suffered by Female Asylum Seekers in France

Women seeking asylum (WSA) are overexposed to sexual violence (SV) in their countries of origin, along migration routes, and within host countries. This overexposure does not cease upon arrival in host countries; on the contrary, the first months following arrival are characterised by heightened vulnerability, with an increased incidence of sexual violence, particularly among women with a prior history of victimisation. Sexual violence has major consequences on physical health, mental health, quality of life, and healthcare utilisation, and generates substantial individual and societal costs. International organisations, including the United Nations High Commissioner for Refugees, have identified the prevention of sexual violence and the improvement of care for survivors as public health priorities. Previous work suggests that addressing sexual violence within primary care, when embedded in a comprehensive, culturally informed, and coordinated approach integrating medical, psychological, social, and medico-legal dimensions, may contribute to preventing the occurrence or recurrence of sexual violence in host countries. However, no comparative study has yet evaluated the effectiveness of such a coordinated model of care on the prevention of sexual violence among women seeking asylum, nor assessed its efficiency or transferability. The primary objective of this study is to evaluate the effectiveness of a coordinated, transcultural, multidisciplinary outpatient care model on the prevention of sexual violence occurring in host European countries among women seeking asylum.

START NOW Adapted: Culturally Adapted Version of START NOW

The goal of this clinical trial is to test the effectiveness of the culturally adapted skills-training START NOW in youth migrant populations. The main question it aims to answer is: Is the culturally adapted skills training START NOW more effective than treatment as usual (TAU) in reducing mental health problems in migrants? Participants will be randomly assigned to the intervention group receiving the skills training START NOW Adapted or the control group receiving TAU. Researchers will compare both groups to see if START NOW Adapted is more effective than TAU in reducing mental health problems in migrants.

Parental Perception of Oral Health-Related Quality of Life in Sudanese Refugee vs. Egyptian Children

This cross-sectional analytical study aims to assess and compare parental perceptions of oral health-related quality of life (OHRQoL) among Sudanese refugee children and Egyptian children aged 6-12 years living in Egypt. The study will include 192 child-parent pairs (96 Sudanese refugees and 96 Egyptians). Data will be collected via a validated Arabic questionnaire adapted from the Child Oral Health Impact Profile (COHIP) and clinical oral health examinations using DMFT/dmft indices, Gingival Index, and Plaque Index. The study seeks to identify disparities in oral health, parental awareness, and access to dental care services, thereby informing future community-based interventions and public health policies targeting vulnerable populations such as refugee children.

Self Help Plus and Post-Migration Living Difficulties Support Intervention

This study will conduct a two-arm, single-blind, randomized controlled trial among Syrian refugee women living in Turkey who experience psychological distress. In the study, participants will be randomly assigned to either the SH+ intervention (n = 105) combined with a session on Post-Migration Living Difficulties (PMLD) or Treatment as Usual (TAU) (n = 105). SH+ is a five-session guided self-help intervention focusing on stress management based on Acceptance and Commitment Therapy (ACT). In addition, a session discussing post-migration difficulties and possible problem-management techniques will be integrated after the SH+ intervention. This study aims to fill an important gap in refugee health and well-being research by focusing on the integrated expansion and implementation of an intervention program to address the psychosocial challenges faced by refugee Syrian women. The results will assess the effectiveness of the intervention on psychological distress, focusing on its potential positive effects on psychological distress, stress management, and adaptation processes. Furthermore, the impact of the intervention on the use of association services and psychological flexibility will be examined.
