The purpose of this study was to test Multi-Process Action Control (M-PAC) processes as correlates of physical activity (PA) intention formation and translation (i.e., action control) in individuals diagnosed with cancer.
This study was a cross-sectional survey, completed from July to November of 2020 during the COVID-19 pandemic. PA and M-PAC processes were self-reported using the Godin Leisure-Time Exercise Questionnaire and questionnaires for reflective (instrumental/affective attitudes, perceived opportunity/capability), regulatory (e.g., goal-setting, planning), and reflexive processes (habit, identity). Separate hierarchical multinomial logistic regression models determined correlates of intention formation and action control.
Participants ( = 347; M= 48.2 ± 15.6) were primarily diagnosed with breast cancer (27.4%) and at a localized stage (85.0%). Most participants intended to perform PA (70.9%), yet only 50.4% met guidelines. Affective judgements ( < 0.001) and perceived capability ( < 0.01) were significantly associated with intention formation. Preliminary models indicated employment, affective judgements, perceived capability, and self-regulation to be significant ( < 0.05) correlates of action control, but in the final model, only surgical treatment ( = 0.02) and PA identity ( < 0.001) were significantly associated with action control.
Reflective processes were associated with PA intention formation, while reflexive processes were associated with PA action control. Behavior change efforts for individuals diagnosed with cancer should extend beyond social-cognitive approaches to include regulatory and reflexive processes of PA behavior (i.e., PA identity).
本研究旨在检验多进程动作控制（M-PAC）过程作为癌症患者身体活动（PA）意图形成和转化（即动作控制）的相关因素。
这是一项横断面调查研究，于 2020 年 7 月至 11 月在 COVID-19 大流行期间完成。PA 和 M-PAC 过程使用 Godin 休闲时间运动问卷和用于反映性（工具/情感态度、感知机会/能力）、监管（例如，目标设定、计划）和反射性过程（习惯、身份）的问卷进行自我报告。单独的分层多项逻辑回归模型确定了意图形成和行动控制的相关因素。
参与者（n=347；M=48.2±15.6）主要被诊断为乳腺癌（27.4%）和局部阶段（85.0%）。大多数参与者打算进行 PA（70.9%），但只有 50.4%符合指南。情感判断（<0.001）和感知能力（<0.01）与意图形成显著相关。初步模型表明，就业、情感判断、感知能力和自我调节是行动控制的重要（<0.05）相关因素，但在最终模型中，只有手术治疗（=0.02）和 PA 身份（<0.001）与行动控制显著相关。
反映性过程与 PA 意图形成相关，而反射性过程与 PA 动作控制相关。针对癌症患者的行为改变努力应超越社会认知方法，包括 PA 行为的监管和反射性过程（即 PA 身份）。
