**Scenario A.** A health psychologist is interested in whether a bedtime routine intervention improves sleep quality in college students. Participants are randomly assigned to one of three groups for two weeks: Follow a structured sleep hygiene routine (e.g., no screens an hour before bed, consistent bedtime, relaxation activity), follow a modified routine that includes screens (watching a show or using social media before bed), maintain their usual bedtime habits (control). At the end of the study, participants complete a sleep quality questionnaire and wear a sleep tracker to record sleep duration.
