Exploring Wellbeing and Sense of Coherence in French-Speaking Women with Breast Cancer: Insights from a Cross-Sectional Study

Introduction: Breast cancer is the most commonly diagnosed cancer worldwide, accounting for about one in eight cancer cases according to the World Health Organization. It significantly impacts physical, psychological, and social aspects of life. Well-being is a complex, multidimensional concept shaped by internal and external factors. The Sense of Coherence (SOC) model provides a useful framework for understanding how individuals cope with health-related stress and maintain well-being. Objective: This study aimed to assess well-being and SOC levels among French-speaking women diagnosed with breast cancer and to identify factors associated with SOC. Methods: A cross-sectional survey was conducted between July and September 2023. Participants were French-speaking women diagnosed with breast cancer. Data were collected through an online self-administered questionnaire covering: (1) sociodemographic and clinical information, (2) well-being using the WHO-5 Well-Being Index, and (3) SOC using the 13-item SOC scale (SOC-13). Data were analyzed using R software. Results: A total of 99 women participated, most of whom lived in France (89.9%). The average age was 47.7 years, and 89.9% had children. Half were diagnosed between 2021 and 2023. Treatments included chemotherapy (54%), radiotherapy (38%), and surgery (35%). The average WHO-5 well-being score was 52.1, and the mean SOC score was 50.6, with subscale scores of 22.0 (comprehensibility), 18.0 (manageability), and 17.0 (meaningfulness). SOC showed a moderate positive correlation with well-being (r = 0.43) and was significantly associated with receiving radiotherapy (p = 0.035) and living alone (p = 0.008). Conclusions: Findings highlight SOC as a key factor in the well-being of women with breast cancer, supporting Antonovsky’s model. Strengthening SOC may enhance resilience and improve quality of life in this population. Future interventions should consider strategies to support SOC development.
