Abstract

Introduction: 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).Material and Methods: 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.Results: 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).Conclusion: 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.
