Music in Dementia Assessment Scales (MiDAS) is a standardized outcome measure aiming to capture the effects of music-based interventions in patients with dementia. It is a unique instrument regarding its specificity, with the potential to enhance research in the field of music in dementia care. The aim of this study was to report a preliminary psychometric study of the translated and adapted instrument to European Portuguese (MiDAS-PT).
Care home residents with dementia attended bi-weekly group music-based interventions, for five weeks. Intervention coordinators and care home staff completed MiDAS ratings at every session and the Quality-of-Life Scale (QoL-AD) at three time-points. Inter-rater reliability, test-retest reliability, internal consistency, concurrent validity (QoL-AD) and construct validity were evaluated.
A total of 529 forms were completed (staff = 235, therapist = 294). Low therapist inter-rater and test-retest reliability, good internal consistency, low concurrent validity, and good construct validity were found. There were high factor loadings between the five MiDAS items (Interest, Response, Initiation, Involvement, and Enjoyment).
This preliminary investigation indicated acceptable psychometric properties on a range of attributes, but more research is needed in order to definitely establish the psychometric value of the scale.
音乐在痴呆评估量表（MiDAS）中是一种标准化的结果衡量标准，旨在评估基于音乐的干预对痴呆症患者的影响。它是一种具有特异性的独特工具，具有增强音乐在痴呆症护理领域研究的潜力。本研究的目的是报告 MiDAS 经翻译和改编为欧洲葡萄牙语（MiDAS-PT）后的初步心理测量研究。
患有痴呆症的养老院居民每两周参加一次基于小组的音乐干预，为期五周。干预协调员和养老院工作人员在每次会议上完成 MiDAS 评分，在三个时间点完成生活质量量表（QoL-AD）评分。评估了组内一致性、重测信度、内部一致性、同时效度（QoL-AD）和结构效度。
共完成了 529 份表格（工作人员=235，治疗师=294）。治疗师的组内一致性和重测信度较低，内部一致性较好，同时效度较低，结构效度较好。五个 MiDAS 项目之间的因子负荷较高（兴趣、反应、发起、参与和享受）。
这项初步研究表明，该量表在一系列属性上具有可接受的心理测量特性，但需要进一步研究以确定该量表的心理测量价值。
