The article that I used for this research example is called “Effects of Music on Depression and Sleep Quality i Elderly People: A randomized Controlled Trial.” I used ProQuest and sorted the articles by scholarly journals. In this article they discuss the effects of music on depression and anxiety in the elderly community. It was a controlled randomized study that was separated into three measures which were: demographic variables, physiological parameters, and physiological parameters. There choices of music were meditative, Chinese classical, western classical, and western modern jazz. The results came back showing that listening to music helps to improve sleep quality and the results of depression lowered as well. I believe this way of collecting data would be beneficial in my research of finding music related to stress levels.
