体力活动对痴呆症患者有益。我们以前开发了一个理论模型来解释痴呆症（PHYT-痴呆症）中身体活动的行为变化。本研究旨在从外部验证该模型。通过对一项促进痴呆症患者活动的方案（PrAISED 2）的过程评价进行了验证。采访了二十名痴呆症参与者及其护理人员，以调查他们对该计划的体验。通过内容分析对数据进行分析。使用模型的原始构造作为初始代码，如果从数据中引出，则生成新代码。这些结构也根据它们在访谈中的频率进行了排名。所有的原始模型结构进行了验证和两个新的结构创建：“个人历史”和“信息/知识”。某些构建体（例如，支持）比其他（例如，个人信仰）。我们提出了修改建议，并将其纳入修订后的模型。PHYT-痴呆症认识到，随着时间的推移，痴呆症对启动和维持行为改变的动机有影响。该模式主张，干预措施应采取比传统的行为改变战略更全面的办法。建议的修订需要进一步验证，以准确预测痴呆症患者体力活动的行为变化。
Physical activity is beneficial for people with dementia. We previously developed a theoretical model to explain behaviour change in physical activity in dementia (PHYT-in-dementia). This study aimed to externally validate the model. Validation occurred through the process evaluation of a programme promoting activity in people with dementia (PrAISED 2). Twenty participants with dementia and their carers were interviewed to investigate their experience of the programme. The data were analysed through content analysis. The original constructs of the model were used as initial codes and new codes were generated, if elicited from the data. The constructs were also ranked, based on their frequency in the interviews. All of the original model constructs were validated and two novel constructs created: 'personal history' and 'information/knowledge'. Certain constructs (e.g., support) were more frequently mentioned than others (e.g., personal beliefs). We suggested modifications and integrated them into a revised model. The PHYT-in-dementia recognised that dementia has an impact on motivation to initiate and maintain behaviour change over time. The model advocates that interventions adopt a more holistic approach than traditional behaviour change strategies. The suggested revisions require further validation to accurately predict behaviour change in physical activity in people with dementia.
