Factors associated with anxiety in colorectal cancer survivors: a scoping review

Abstract

Purpose Anxiety is one of the most common psychological issues among colorectal cancer (CRC) survivors. It can interact with physical symptoms, impacting cancer progression, survival, and quality of life. This scoping review aims to explore the factors associated with anxiety in patients with CRC and the instruments used to measure anxiety. Methods Using Arksey and O’Malley’s (2005) framework for the scoping review, studies investigating anxiety in CRC patients published in CINAHL, PubMed, PsycINFO, and Scopus between 2013 and 2024 were included. Results We analyzed fifty-one studies for this review. The review identified several risk factors and consequences of anxiety in CRC patients. The risk factors were classified into six domains using Niedzwiedz et al.'s (2019) framework: individual characteristics, social/ contextual factors, prior psychological factors, psychological responses to diagnosis and treatment, characteristics of cancer, and treatment. The consequences of anxiety were classified into three categories: global health status/quality of life, functions, and symptoms/problems. The most frequently used tool was the Hospital Anxiety and Depression Scale, with International Classification of Diseases codes being the second most used. Conclusions This scoping review highlighted the intricate interaction between biological and psychosocial aspects in the lives of CRC survivors. It also identified unique factors associated with anxiety among these individuals. However, the review found some inconsistencies in the results related to anxiety-related factors, potentially due to differences in study populations, designs, measurement tools, and analysis methods. Implications for Cancer Survivors. This review underscores the potential for interventions targeting modifiable factors to prevent or reduce anxiety and enhance the quality of life for CRC survivors.
