Excerpt
I was collecting data for a study about the effectiveness and side effects of a variety of colon-cleansing preparations. I also explained the study to potential subjects and asked whether they would like to participate. The purpose of the study was to describe bowel-cleansing preparations used at various institutions across the United States, their cleansing effectiveness, and any resulting discomfort. Three data collection forms were used in the study, and I was responsible for collecting data for two of them. A physician and an endoscopy nurse completed the third form during colonoscopy.
According to Burns and Grove (2009), data collection includes (1) selecting subjects; (2) obtaining informed consent; (3) ensuring that data are collected in the same way for all subjects; and (4) solving problems that occur while collecting data. The following sections describe the problems I encountered that interfered with data collection, and how I solved them.
