Cognitive impairment is present in the majority of individuals with first-episode psychosis (FEP) and is a strong predictor of long-term functional disability. Despite this, evidence-based cognitive interventions are rarely available in routine mental healthcare in low-income and middle-income countries, where most young people with psychosis reside. This protocol describes the CognIFied study, a pilot randomised controlled trial evaluating the feasibility and acceptability of a culturally adapted, task-shifted compensatory cognitive training (CCT) intervention for young adults with FEP in Nigeria.

CognIFied is a multicentre, assessor-blind, parallel-group pilot randomised controlled trial with an embedded mixed-methods process evaluation. The study will recruit 180 young adults aged 18–30 years with Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5)-defined FEP (onset within the past 5 years) and objective cognitive impairment from three public psychiatric hospitals in Nigeria. Participants will be randomised 1:1 to receive either culturally adapted CCT or an active control condition, Enhanced Recreational Therapy. Both interventions comprise 12 weekly group sessions lasting 60–90 min. CCT is delivered by trained psychiatric social workers using a manualised curriculum co-designed with young people with lived experience. Primary outcomes assess feasibility (recruitment, retention, intervention adherence), acceptability (Client Satisfaction Questionnaire-8) and intervention fidelity. Secondary outcomes include preliminary signals of effectiveness on global cognitive functioning (Brief Assessment of Cognition in Schizophrenia) and functional capacity (University of California, San Diego [UCSD] Performance-Based Skills Assessment), assessed at baseline and at 3, 6 and 12 months. Quantitative analyses will be descriptive and exploratory, supplemented by qualitative inquiry guided by Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) and Consolidated Framework for Implementation Research frameworks and an exploratory economic evaluation.

Ethical approval has been obtained from relevant institutional review boards. Findings will be disseminated through open-access publications, policy-focused stakeholder engagement and community dissemination co-led by a Youth Research Team.

Strengthening research capacity in Africa is vital for tackling pressing health, educational and socioeconomic challenges facing the continent. At the core of this effort is the cultivation of innovative research leaders through postgraduate training programmes that incorporate mentorship-infused supervision. Such models have demonstrated potential in improving research skills, boosting academic productivity and fostering leadership development among emerging scholars. This systematic review and meta-synthesis protocol aims to examine existing mentorship-infused supervision practices across African higher education institutions. The review seeks to identify effective models, uncover common challenges and barriers, and generate evidence-based recommendations to develop sustainable, contextually relevant strategies. Insights from this work will inform policies and practices to enhance postgraduate research training, advance research leadership and contribute to the broader goal of strengthening research ecosystems across Africa.

A systematic review and thematic meta-synthesis will be undertaken, focusing on qualitative research studies as well as the qualitative components of mixed-methods studies. Relevant studies published in English will be identified through a comprehensive search strategy. The electronic databases, including Medline/PubMed, Scopus, Web of Science, African Journals Online, EMBASE and CINAHL, will be searched to capture a wide range of peer-reviewed articles and grey literature. Databases will be searched from March 2026. Two reviewers will independently perform study selection, data extraction, quality assessment and evaluation of risk of bias, using the Critical Appraisal Skills Programme checklist.

This systematic review and meta-synthesis will analyse publicly available literature and does not require ethical approval, as it involves no primary data collection. It will adhere to established ethical and methodological standards, including proper citation and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The findings will be widely disseminated through open-access journal publication, conference presentations and targeted reports for universities, research institutions and policymakers to inform and support mentorship-based postgraduate research supervision across Africa.
