Predisposing, Precipitating, and Perpetuating Factors of Insomnia in Cancer Survivors
Objective
To identify the factors contributing to insomnia in cancer survivors, including those that make it more likely, those that trigger it, and those that maintain it at subthreshold, moderate, and severe levels.
Sample & Setting
- 135 cancer survivors participating in a clinical trial on insomnia treatment
- Participants self-reported symptom severity on the Insomnia Severity Index
Methods & Variables
- Assessment of predisposing factors (age, sex, race and ethnicity, body mass index)
- Assessment of precipitating factors (number of years since cancer diagnosis, depression and anxiety symptoms, health-related quality of life)
- Assessment of perpetuating factors (frequency of consuming alcoholic and caffeinated beverages, napping behavior, dysfunctional beliefs about sleep)
Results
In the study, being female was found to have a protective effect against insomnia, while being a person of color, having higher anxiety, more depression symptoms, and stronger dysfunctional beliefs about sleep were significantly associated with greater insomnia severity.
Implications for Nursing
- Fostering interprofessional collaboration and implementing evidence-based interventions can help nurses contribute to the well-being of cancer survivors and address their sleep-related challenges.
- This study highlights the importance of regular insomnia screenings for cancer survivors, with nurses playing an essential role in facilitating this process.
