评估渐进性降低应激阈值(PLST)概念模型作为对痴呆行为症状的解释，并测试其假设的几个命题。PLST模型表明，由于应对方面的障碍，痴呆症患者的压力阈值降低，随着压力的全天积累，痴呆症的行为症状会更多。密集的纵向设计。在2019年7月至2020年8月期间，N名家庭照顾者的样本完成了21天的简短每日日记调查，总共报告了2841天。使用动态结构方程模型作为分析技术，考察照顾者和照顾者环境应激源对痴呆行为症状多样性的影响，以解释嵌套数据结构和自回归关系。结果表明，环境应激源与当天和第二天痴呆症行为症状的多样性直接相关。研究结果为PLST模型命题提供了支持。此外，研究结果表明，考虑到暴露/恢复轨迹的证据，以及压力暴露对痴呆表现的行为症状的滞后影响，扩展概念模型是必要的。这项研究测试了一种常用的护理模式是否确实解释了痴呆症行为症状的发生。主要研究结果支持使用该模型作为干预框架，并建议该模型应调整以考虑复苏轨迹。由于痴呆症的行为症状代表复杂和动态的时间现象，传统的纵向评估和分析不足以测试模型。研究结果有助于为痴呆症治疗的行为症状设计环境改进型干预措施，以及评估这种干预措施的方法。
To evaluate the progressively lowered stress threshold (PLST) conceptual model as an explanation for behavioural symptoms of dementia and test several of its hypothesized propositions. The PLST model suggests that due to impairments in coping, persons living with dementia have a reduced threshold for stress and respond with more behavioural symptoms of dementia as stress accumulates throughout the day. Intensive longitudinal design. A sample of N = 165 family caregivers completed brief daily diary surveys for 21 days between the dates of 7/2019 and 8/2020, reporting on a total of 2841 days. Dynamic structural equation modelling was used as the analytic technique to examine the impact of caregiver and care recipient environmental stressors on the diversity of behavioural symptoms of dementia to account for the nested data structure and autoregressive relationships. Results show direct relationships between environmental stressors and diversity of behavioural symptoms of dementia that same day and the following day. Findings provide support for the PLST model propositions. Further, findings suggest an extension to the conceptual model is warranted given evidence of an exposure/recovery trajectory and the lagged effects of stress exposure on behavioural symptoms of dementia presentation. This study tested whether a commonly used nursing model does in fact explain the occurrence of behavioural symptoms of dementia. The main findings support using the model as an intervention framework and suggest the model should be adapted to consider recovery trajectories. Since behavioural symptoms of dementia represent complex and dynamic temporal phenomena, traditional longitudinal assessments and analyses are an insufficient measurement modality for testing models. Findings inform the design of environmental‐modification type interventions for behavioural symptoms of dementia management and the methods to evaluate such interventions.
