In determining a study's feasibility, which of the following statements are true, regarding the time needed for study completion? (Select all that apply.)
a. Some data collection must be performed over an extended period of time, such as measurements of the depth and extent of scar tissue over 18 months.
b. Sufficient subjects meeting the study criteria may be difficult to access, requiring data collection that extends for months or even years.
c. The inflationary spiral makes all research funding inadequate.
d. Computerized records make data analysis much less time-consuming.
e. Obtaining Institutional Review Board (IRB. approval may be time-consuming, especially if the research uses more than one hospital or agency.
ANS: A, B, E
One can approximate the time needed to complete a study by assessing the following factors: (1) type and number of subjects needed, (2) number and complexity of the variables to be studied, (3) methods for measuring the variables (are instruments available to measure the variables, or must they be developed?), (4) methods for collecting data, and (5) the data analysis process. Another factor that can increase the time needed for a study is obtaining institutional review board (IRB) approval, especially if more than one clinical agency is used for data collection in a study. Not all research funding is inadequate. Computerized records may be easier or may be more difficult for data retrieval; however, data analysis is not affected by the existence of computerized data.
