Sense of coherence in family caregivers of children with chronic diseases: a narrative review.

In recent years, as the prevalence of chronic diseases in children continues to increase significantly in the world, family caregivers who undertake long-term care responsibilities are increasingly facing a huge psychological burden. As the core theoretical construction of positive psychology, Antonovsky's Sense of Coherence (SOC) has become an important psychological resource that enables caregivers to actively cope with the multiple stressors inherent in the care process and maintain their physical and mental balance. This article reviews the research status of sense of coherence in family caregivers of children with chronic diseases, including the theoretical connotation and evolution of sense of coherence, the psychometric characteristics of existing measurement tools, a variety of influencing factors, and the current mainstream intervention strategies. In addition, the review critically dissects controversies, methodological flaws, and inherent gaps in the current body of literature and suggests targeted directions for future research. This study aims to provide a solid theoretical and empirical basis for clinicians to formulate targeted intervention programs, so as to improve the mental health status of family caregivers and optimize the overall care system for children with chronic diseases.
