完善提示利用和参与痴呆症进餐时间视频编码方案，并检查其易用性，可行性和评估者之间的可靠性，在评估食物摄入过程和二元语言和非语言的互动。这项研究是对2011-2014年期间在痴呆症沟通试验中收集的110个进餐时间互动录像观察结果的二次分析。这些视频涉及9家养老院的29名工作人员和25名痴呆症患者（42名独特的工作人员-居民配对）。2018-2019年进行了数据编码和分析。收集了编码挑战与匹配解决方案和编码时间的列表。通过对四名经过培训的编码员随机选择的22个视频进行评分，检查了评分员间的可靠性。使用改进的编码方案对一小时的视频进行编码平均花费10.81小时。编码的挑战，包括识别关键的摄入过程的特点和类似的语言或非语言行为的区别，确定了适当的解决方案。改良编码方案具有良好的评定者间信度（Cohen's Kappa范围= 0.93 - 0.99，95%CI = 0.92 - 0.99）。调查结果支持的可行性，可用性和评分员之间的可靠性的改进编码方案的初步证据。未来的心理测试需要在不同的护理环境中的痴呆症患者的不同人群。现有的评估食物摄入过程和二元相互作用的工具很少，可行性和/或可靠性有限，无法捕捉进餐时间护理的复杂性和动态。改进后的编码方案显示了初步的可行性、可用性和评分者间信度。考虑到时间强度和所获得数据的丰富性之间的平衡，该工具在解决某些研究问题（例如，表征和聚类二元行为，行为和摄入量之间的时间关系），涉及患有或不患有痴呆症的老年人及其正式或非正式照顾者。
To refine the Cue Utilization and Engagement in Dementia mealtime video-coding scheme and examine its ease of use, feasibility and inter-rater reliability in assessing the food intake process and dyadic verbal and nonverbal interactions. This study was a secondary analysis of 110 videotaped observations of mealtime interactions collected under usual care conditions from a dementia communication trial during 2011–2014. The videos involved 29 staff and 25 residents with dementia (42 unique staff-resident dyads) in nine nursing homes. Data coding and analysis was performed in 2018–2019. Logs of coding challenges with matched solutions and coding time were collected. Inter-rater reliability was examined through rating of randomly selected 22 videos across four trained coders. It took a mean of 10.81 hours to code a one-hour video using the refined coding scheme. Coding challenges, including identification of key intake process characteristics and differentiation of similar verbal or nonverbal behaviors, were identified with appropriate solutions. The refined coding scheme had good inter-rater reliability (Cohen’s Kappa range = 0.93 – 0.99, 95% CI = 0.92 – 0.99). Findings supported preliminary evidence on feasibility, usability and inter-rater reliability of the refined coding scheme. Future psychometric testing is needed in diverse populations with dementia across different care settings. Existing tools assessing the food intake process and dyadic interactions are few and have limited feasibility and/or reliability and fail to capture the complexity and dynamics of mealtime care. The refined coding scheme showed preliminary feasibility, usability and inter-rater reliability. In consideration of the balance between time intensity and the richness of data obtained, the tool may be appropriate and useful in addressing certain research inquires (e.g., characterizing and clustering dyadic behaviors, temporal relationship between behaviors and intake) pertaining older adults with or without dementia and their formal or informal caregivers.
