Stepped-Care Support for Children With Leukaemia

This study aims to develop, culturally adapt, and pilot test a stepped-care psychosocial intervention designed to improve emotional and behavioral health among children with leukemia in Pakistan. Children with leukemia may experience anxiety, depressive symptoms, irritability, sleep disturbance, social withdrawal, treatment-related distress, and behavioral difficulties during the cancer treatment pathway. In resource-constrained settings, structured psychosocial care is often limited or unavailable within routine pediatric oncology services. This study addresses this gap by developing a feasible, culturally responsive, and theory-informed intervention that can be delivered within existing clinical resources. The study follows a multi-stage intervention-development process guided by the Intervention Mapping framework and Medical Research Council guidance for complex interventions. The stages include: evidence review and expert consultation to identify gaps in current psychosocial care; mixed-methods needs assessment with children, caregivers, and healthcare professionals; refinement of the intervention through focus groups and an e-Delphi process; and pilot testing of the intervention in a two-arm pilot randomized controlled trial. The pilot trial will include children aged 7 to 14 years with leukemia who are clinically stable and in the remission or maintenance phase of treatment, together with their primary caregivers. Participants will be allocated to either the stepped-care intervention plus routine care or routine care alone. The stepped-care program is delivered over 12 weeks and progresses from low-intensity universal support to more intensive individualized care according to child and family needs. Intervention components include an information booklet, psychoeducational video, face-to-face psychoeducation, peer support, cognitive behavioral strategies, parent-child behavioral training, and one-to-one therapy or referral when indicated.
