针对癌症幸存者健康行为改变的干预措施越来越多地被开发出来。这项研究验证了成人幸存者群体中体力活动和水果和蔬菜 (F/V) 消费的决策平衡措施。参与者为 N=86 名患者，他们至少 5 年前完成了乳腺癌或前列腺癌的初级治疗，并参加了旨在改善身体活动和营养行为的电子健康干预措施。在基线和 3 个月时评估决策平衡、变化阶段、F/V 消耗和体力活动。因子分析用于评估决策平衡措施的结构。通过混合模型分析评估决策平衡、阶段和行为结果之间的关系。每个措施的双因素结构都得到支持。两种行为的不同阶段的优点和缺点都不同（p < .0001）。任务单元的总代谢当量 (MET) 与决策平衡的优点 (p = .012) 和缺点 (p = .003) 相关。 F/V 消耗与决策平衡优点显着相关 (p = .0003)，但与缺点无关 (p = .112)。总体而言，研究结果验证了这些决策平衡措施作为健康行为指标的有效性，并支持在进一步研究中使用这些措施的价值，以帮助了解该人群的行为变化。
Interventions directed at health behavior change are increasingly being developed for cancer survivors. This study validates decisional balance measures for physical activity and fruit and vegetable (F/V) consumption among an adult survivorship population. Participants were N=86 patients who completed primary treatment for breast or prostate cancer at least 5 years previously and were enrolled in an e-health intervention that aimed to improve physical activity and nutrition behaviors. Decisional balance, stage of change, F/V consumption, and physical activity were assessed at baseline and 3 months. Factor analysis was used to assess the structure of the decisional balance measures. The relationship between decisional balance, stage, and behavioral outcomes was assessed with mixed model analyses. The two factor structure of each measure was supported. Pros and cons differed across stages of change for both behaviors (p’s < .0001). Total Metabolic Equivalent of Task units (METs) were related to decisional balance pros (p = .012) and cons (p =.003). F/V consumption was significantly associated with decisional balance pros (p = .0003), but not cons (p = .112). Overall, findings provide validation for these decisional balance measures as indicators of health behaviors and support the value of using these measures in further research to aid understanding of behavior change in this population.
