(02.05 MC)A study was conducted with 55 adults who were not getting the recommended amount of sleep for their age group and who experienced documented instances of difficulty with coworkers. All adults voluntarily participated in the study, provided full informed consent, and knew they could withdraw at any point. Participants were randomly assigned to a group that gradually advanced their bedtime by five minutes each night or to a control group that maintained their normal sleep schedule. After two weeks, all participants completed a mood assessment. The study’s purpose was revealed to participants after its completion. Data was published that included place of employment and position. Which of the following guidelines would be viewed as problematic by an institutional review board (IRB)?
