In research, a single-subject design studies one or a few subjects closely, rather than studying groups. Multiple baseline designs resolve common problems associated with other single-subject designs; however they have their own limitations. Which of the following is a problem associated with multiple baseline designs?
  1. Time investment
  2. Ethical concerns
  3. Threat of history
  4. Failure of variable to return to baseline
Explanation
Answer: A - Time investment and financial investment are problems associated with multiple baseline design. AB design carries the threat of history-it is hard to determine whether intervention or another event caused change. Ethical concerns and the failure of a dependent variable to return to baseline are both problems associated with ABAB design.
