| Summary: | 碩士 === 國立台北護理學院 === 護理研究所 === 93 === The objective of this study is to investigate the effectiveness of music therapy on the agitation levels of institutionalized elderly with dementia. A time series with withdrawn and reinstituted treatment was used to design the study. The Purposive Sampling technique is used; the sample is taken in a dementia care unit of a nursing home in Taipei, and the total sample size is forty-one.
The research instruments include: structuralized demographic questionnaire, Mini-Mental State Examination (MMSE), Barthel Activity of Daily Living, and Cohen-Mansfield Agitation Inventory (CMAI). The software used to analyze data is SPSS v12.0 for Windows and SAS v9.1. The statistical methods are two-folds. Percentage, average, mean, and standard deviation is for describing sample; Mann-Whitey U test, Kruskal-Wallis test, Spearman’s r, and GEE analysis are for inferential statistics.
The statistics of the study is as followed. The mean age of the participants is 81.68±6.39 years old. The age range is 69~94 years old. The mean score for MMSE is 10.66±6.85. The majority of the MMSE group lies between 0 to 9 scores. The mean Barthel Activity of Daily Living is 56.83±38.12. The majority of the Barthel Activity of Daily Living group lies between 61 to 90 scores.
53.7% of residents of the nursing home are physically restrained. The most frequently used types of restraints are belt on wheel chair, palm binder and limb belt.
Negative correlation is found between MMSE and physical aggressive behaviors(γ=-.44，P<.01). Positive correlation is observed between the Barthel Activity of Daily Living and physical nonaggressive behaviors (γ=.60，P<.001). The following hypotheses show statistically significant difference; the intake of antipsychotic and physical nonaggressive behaviors (P<.05), the intake of antidepressant and CMAI total scores (P<.05), physical aggressive behaviors (P<.05) and verbal aggressive behaviors (P<.05), the number of drugs taken and Physical nonaggressive (P<.05). In addition, the use of physical restraints shows significant difference in both physical nonaggressive behaviors (P<.001) and physical aggressive behaviors (P<.05).
Using GEE model analysis, the result proves that music therapy statistically significantly improves both physical and verbal aggressive behaviors. There is a one-week time lag on effectiveness of music therapy.
The results might serve as a reference for future treatment of behavior problems for the elderly with dementia.
