Psychology Professor’s Research has International Appeal

The Sleep Hygiene Index was developed by UA Little Rock Psychology Professors to assess sleep hygiene behaviors. The index is applied extensively in sleep research and has been translated into 11 languages: Turkish, Russian, Persian, Italian, Hindi, Korean, Formosan Mandarin Chinese, Portuguese, Spanish, Japanese, and Lithuanian. In addition to it’s international appeal, the index is also used widely in the US including at the Johnson NASA Space Center in Houston, TX.

Dr. David Mastin and Dr. Robert Corwyn, both Professors of Psychology at UA Little Rock, and Jeff Bryson, Professor of Psychology at Fielding Graduate University, originally presented the Sleep Hygiene Index (SHI) in the research paper entitled “Assessment of Sleep Hygiene Using the Sleep Hygiene Index,” which was published in the Journal of Behavioral Medicine in 2006. The index is a series of 13 self-administered questions meant to assess the practice of sleep behaviors. The SHI is heavily cited in scholarly journals and popular publications.

Dr. Mastin earned his PhD in Psychology from the University of Southern Mississippi before joining the faculty at UALR in 2000. In 2013, he won the College of Arts, Humanities and Social Sciences (CAHSS) Faculty Excellence Award for Research and Creative Endeavors. As an experienced researcher, Dr. Mastin is always looking for students to mentor and train in psychological research.

Dr. Corwyn joined the faculty at UA Little Rock in 2004 after earning his PhD in Educational Psychology and Research from the University of Memphis. Dr. Corwyn also won the CAHSS Faculty Excellence Award for Research and Creative Endeavors in 2010. Dr. Corwyn also invites students to contact him if they are interested in psychological research.
