Factors related to the resilience and mental health of adult cancer patients: a systematic review.

Purpose It has been reported that maintaining the mental health of cancer patients is a critically important issue, and that resilience is related to mental health. This study conducted a systematic literature review in order to fully understand the relationships between resilience and anxiety, depression, and quality of life (QOL) in adult cancer patients, as well as identify factors associated with resilience. Methods The PubMed, CINAHL, Psychology Database, and ICHUSHI Web databases were searched for articles related to resilience in cancer patients published between 2014 and 2019 using the keywords "cancer" and "resilience," connected with "and." The extracted articles that met inclusion criteria were organized using a matrix. To understand the resilience status of adult cancer patients, meta-analyses were performed using resilience scores measured with the most commonly used resilience scale, Connor-Davidson Resilience Scale 25. Results Thirty-nine articles were included in the analysis. A higher resilience score is associated with lower anxiety and depression scores and higher QOL scores. Factors related to resilience include personal factors such as age and gender, disease-related factors such as the presence or absence and severity of physical symptoms, and internal factors such as self-efficacy and hopefulness. Conclusions It was found that it is important for cancer patients to improve resilience to maintain mental health and QOL. The findings suggest that providing interventions for factors that will reduce resilience will provide support for patients with cancer.
