Objective: Fear of cancer recurrence (FCR) adversely affects quality of life, but health behaviors such as physical activity (PA) and fruit and vegetable intake (FVI) may help alleviate FCR for some survivors. This cross-sectional study tested the common-sense model (CSM) of FCR by investigating associations between constructs from the CSM (perceived illness consequences, control over health, and timeline), and survivors’ health behaviors, health self-efficacy, and FCR.
Methods: Using wave 3 data from the American Cancer Society Longitudinal Study of Cancer Survivorship-I, path analyses were conducted among mixed-cancer participants (N = 2,337) who were on average 8.8 mean years post-diagnosis.
Results: A final good fitting model [χ2 (5, N = 2,337) = 38.12, p < 0.001; SRMR = 0.02; CFI = 0.99; RMSEA = 0.05] indicated that perceiving fewer illness consequences, and greater control over one’s health, were directly associated with higher PA (β = 0.15 and −0.24, p < 0.01, respectively) and higher health self-efficacy (β = 0.24, −0.38, p < 0.01, respectively). Timeline (i.e., perceiving cancer as chronic) was directly associated with lower health self-efficacy (β = −0.15, p < 0.01) and higher FCR (β = 0.51, p < 0.01). Both greater PA and FVI were directly associated with higher health self-efficacy (β = 0.10 and 0.11, p < 0.01, respectively) which in turn showed a direct association with lower FCR (β = −0.15, p < 0.01).
Conclusion: Increasing survivors’ sense of control over health, decreasing perceived chronicity of the illness, and mitigating its consequences may increase their health behaviors and health self-efficacy, which in turn could decrease their FCR. Longitudinal and experimental studies are needed to confirm these findings.
客观的：对癌症复发 (FCR) 的恐惧会对生活质量产生不利影响，但身体活动 (PA) 和水果和蔬菜摄入量 (FVI) 等健康行为可能有助于减轻某些幸存者的 FCR。这项横断面研究通过调查来自 CSM 的构造（感知疾病后果、对健康的控制和时间线）与幸存者的健康行为、健康自我效能感和 FCR 之间的关联，测试了 FCR 的常识模型 (CSM) .
方法：使用来自美国癌症协会癌症生存纵向研究的第 3 波数据，在混合癌症参与者中进行了路径分析（N = 2,337) 诊断后平均 8.8 年。
结果: 一个最终良好的拟合模型 [χ2 (5,N = 2,337) = 38.12, 磷< 0.001; SRMR = 0.02；CFI = 0.99；RMSEA = 0.05] 表明，感知更少的疾病后果和更好地控制自己的健康，与更高的 PA 直接相关（β = 0.15 和 -0.24， 磷 < 0.01，分别）和更高的健康自我效能（β = 0.24, -0.38, 磷< 0.01，分别）。时间线（即认为癌症是慢性的）与较低的健康自我效能感直接相关（β = -0.15， 磷 < 0.01) 和更高的 FCR (β = 0.51, 磷< 0.01)。更大的 PA 和 FVI 都与更高的健康自我效能感直接相关（β = 0.10 和 0.11， 磷 < 0.01），这反过来表明与较低的 FCR 直接相关（β = -0.15， 磷 < 0.01)。
