Objective: To examine sleep health within a self-determination framework across a diverse college sample. Participants: A nonclinical sample of undergraduate students (n = 399) from a large, urban, public university in the Mid-Atlantic United States in Spring 2020. Methods: Participants were recruited via an online research participation portal and received extra credit for participation. All measures were administered via an online survey. Results: Basic psychological need satisfaction was associated with sleep health. This association was partially mediated by sleep hygiene but not by regulatory style. There were no racial/ethnic differences in sleep health, sleep hygiene, basic need satisfaction, or regulatory style. Men reported more maladaptive motivational styles for sleep health, and non-binary/transgender students reported worse sleep hygiene. Conclusion: Basic psychological need satisfaction and sleep hygiene are critical targets for intervention across diverse college student populations. Motivation may be less critical for nonclinical interventions.
