Psychosocial Intervention Programs for Parents of Children with Cancer: A Systematic Review and Critical Comparison...

Intervention programs have been developed to help parents cope with their child's cancer. Despite some studies reporting a high level of evidence, it is unclear how these programs build on each other. Appraising models of change is critical to advance scientific knowledge and provide evidence-based interventions. This review aims to identify existing programs, explicitly formulate their underlying models, evaluate how they translate into concrete activities, as well as identify and discuss their development process. Eleven programs based on models of change from cognitive-behavioral, systemic and counselling theories were identified. Many models included a sound theoretical framework, targeted outcomes, as well as implementation strategies. In most cases, preliminary development studies were conducted, but details were rarely provided on how development stages informed the redesign of intervention programs. Acceptability and treatment fidelity were not available for one-third of the programs. Future reports should document the development and design redesign stages prior to conducting efficacy trials, as this step would provide crucial details to critically appraise programs.
