Examining the effects of sleep education on sleep hygiene

          The average hours of sleep among college students has reduced over the years. Poor sleep has been associated with deficits in attention, reduction in academic performance, impaired driving, risk-taking behaviors,depression, impaired social relationships, and poorer health. It is believed that college students may have limited knowledge about sleep hygiene and the behaviors that supports sleep health, which may lead to poor sleep hygiene behavior (Dietrich et al., 2016). In this fictitious study examining the effects of sleep education on sleep hygiene, students were randomly assigned to either participate in a formal sleep education program or a control program (on group work). Sleep hygiene behavior was assessed at the conclusion of the study using a self-report Likert-based questionnaire. Question: What is the independent variable? What is the dependent variable?
