目的：涉及严重精神疾病个体的体力活动干预研究往往没有任何理论框架。本研究旨在探讨跨理论模式（TTM）在严重精神疾病患者中的建构效度，以指导未来的身体活动干预。研究方法：54个人完成了调查，询问他们目前的身体活动，自我效能的变化阶段，以及更多的身体活动的优势和劣势。结果：大多数人报告说，在准备阶段的TTM。随着个体接近行动和维持阶段，自我效能和身体活动的感知益处显着增加。虽然所感受到的不利条件随着每一个后续阶段而减少，但这种变化并不显著。结论：这项研究的结果支持TTM在这一人群中的应用，以结构的身体活动干预措施，自我效能，感知的好处和障碍，身体活动不同的阶段和变化的方向预测的理论。
Objective: Physical activity intervention research involving individuals with serious mental illness are often not based on any theoretical framework. This study examined the construct validity of the Transtheoretical Model (TTM) in individuals with serious mental illness to guide future physical activity interventions. Methods: Fifty-four individuals completed surveys that asked about their current stage of change for physical activity, self-efficacy, and perceived advantages and disadvantages of being more physically active. Results: Most individuals reported being in the preparation stage of the TTM. As individuals approached the action and maintenance stages, self-efficacy and perceived benefits of physical activity increased significantly. Although perceived disadvantages decreased with each successive stage, this change was not significant. Conclusions: This study's findings support the TTM's application in this population to structure physical activity interventions given that self-efficacy, perceived benefits of and barriers to physical activity differed across stages and changes were in the direction predicted by theory.
