Testing a Theoretical Model of Perceived Self-efficacy for Cancer-Related Fatigue Self-management and Optimal Physical Functional Status
Open accessAbstract
BACKGROUND: Critical gaps exist in the understanding of cancer symptoms, particularly for cancer-related fatigue (CRF). Existing theories and models do not examine the key role perceived self-efficacy (PSE) plays in a person's ability to manage symptoms. OBJECTIVES: The objective of this study was to test the hypothesis that physical functional status (PFS) is predicted through patient characteristics, CRF, other symptoms, and PSE for fatigue self-management in persons with cancer. METHODS: This study is a secondary data analysis from the baseline observation of two randomized control trials. The combined data set includes 298 participants who were undergoing a course of chemotherapy. Key variables included physiological and contextual patient characteristics, the severity from CRF and other symptoms, PSE, and PFS. Path analysis examined the relationships among the variables in the proposed theoretical model. RESULTS: Persons with cancer reported CRF as the most prevalent symptom among a mean of 7.4 other concurrent symptoms. The severity from CRF had a direct and indirect effect on PFS, with CRF having a direct adverse impact on PFS (t = -7.02) and an indirect adverse effect as part of the severity from the other symptoms (t = 9.69), which also adversely impacted PFS (t = -2.71). Consistent with the proposed theoretical model, PSE had a positive effect on the PFS (t = 2.87) of persons with cancer while serving as a mediator between CRF severity and PFS. DISCUSSION: Cancer-related fatigue is prevalent and related to the presence of other symptoms, and PSE for fatigue self-management is an important factor influencing CRF and PFS. A foundation is provided for future intervention studies to increase PSE to achieve optimal PFS in persons with cancer.

Self-efficacy (confidence in one's capability to influence one's fatigue) is thought to promote adaptive health behaviors and mediate CRF severity.
“Self-efficacy, that is, one's confidence in their capability to influence one's fatigue, is also thought to promote adaptive health behaviors and mediate CRF severity.14,15”
From Exploring the dynamic interconnectedness of protective and perpetuating factors of cancer-related fatigue (2023) · cites this paper as [14]
The Discussion (Hypothesis 3; page not provided) links perceived self-efficacy to health-promoting self-management behaviors, although it says those behaviors were not measured in this study. It finds that self-efficacy mediates the relationship between CRF severity and physical functional status—not CRF severity itself. (LLM, conf=0.88)

“14,15 As for perpetuating factors, a direct link has been found between worrying and CRF, as worrying is thought to perpetuate CRF through endless pessimistic cognitions focused on physical health.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
