Abstract Introduction Social workers are well-positioned to promote healthy sleep behaviors among underserved populations; however sleep health training is rarely integrated into social work curriculums. To address this gap, our interdisciplinary team developed a 2-hour online sleep health educational module for social work students. The module was grounded in best e-learning pedagogical principles, and based on qualitative formative research. We tested the initial impact and acceptability of the module. Methods We recruited 32 social work students at a Florida University via a departmental listserve. Pre- to post-intervention changes in the Sleep Beliefs Scale (SBS) and the Sleep Practices and Attitudes Questionnaire (SPAQ) were assessed using Wilcoxon Signed-Rank tests. We conducted qualitative research to assess intervention acceptability,and to inform future iterations of the program. Results Mean age was 29.5±11.6 yrs, 100% were female, and primarily Non-Hispanic White (41.9%), followed by African American/Black (35.5%), and Hispanic/Latino (22.6%). Results showed pre/post intervention improvements in both the Sleep Beliefs Scale (14.7±2.2 vs.16.9±2.6 [p=.002]; higher score=higher knowledge) and SPAQ (2.1±0.6 to 1.5±0.6 [p=.001]; lower score=higher importance of sleep) indicating improvements in knowledge surrounding healthy sleep behaviors and the importance of sleep for overall health (respectively). Qualitative data supports the intervention’s acceptability and utility. When asked what participants liked best about the module, responses included: “I was educated and am better prepared to offer some insight to my clients and staff”; “..they offer resources we can use for ourselves and our clients;” and “easy to navigage, and full of useful information.” Suggestions for improvement included shortening the module’s length. Conclusion Assessment of an online sleep health educational module indicates a promising impact on sleep health knowledge. A larger study is planned to more definitively evaluate the module’s impact and acceptability among social work students. Support American Academy of Sleep Medicine Foundation
