The purpose of this dissertation was to examine the associations between sleep problems, sleep hygiene and ADHD symptoms in young adults. The first chapter of this dissertation provides an overview of ADHD in adulthood, and a review of the literature that has associated ADHD and sleep problems. This chapter also highlights the need to develop a valid and reliable instrument to assess sleep hygiene. The second chapter presents a manuscript which outlines the development of a new self-report measure of sleep hygiene in young adults. Exploratory and confirmatory factor analyses were used to develop two sleep hygiene scales (substance abuse and poor sleep scheduling) and overall results indicated that the new instrument has sound psychometric properties, as well as good construct and convergent validity. The third chapter presents a manuscript which outlines two empirical studies that examined the associations between sleep problems, sleep hygiene and ADHD symptoms in young adults. Results indicated that young adults with elevated ADHD symptoms reported more sleep problems (specifically insomnia and sleepiness) and poorer sleep hygiene (specifically substance abuse and poor sleep scheduling) than young adults without elevated ADHD symptoms. Young adults with ADHD also reported more sleep problems even after accounting for substance abuse and poor sleep scheduling, suggesting that poor sleep hygiene is not responsible for the sleep problems of young adults with ADHD. The fourth chapter presents a summary of the research findings, as well as a discussion of the methodological limitations and directions for future research.
