“…For example, poor sleep quality has been shown to be associated with lower academic aspirations, motivation, and achievement among high school and college students (e.g., Önder et al, 2014; Tonetti et al, 2015). It has also been associated with mental health problems, including depression and anxiety symptoms, and even suicidal thoughts (e.g., Rubens et al, 2017; Tampke et al, 2019) as well as current and long-term alcohol, cannabis, marijuana, and other illicit drug use among both adolescents and adults, although substance use itself also potentially contributes to poorer sleep (e.g., Mike et al, 2016; Pires et al, 2016). In sum, these observed problems have great implications on youth and young adult well-being and future development.…”

Sleep is closely related to physical and mental health problems as well as problem behaviors among adolescents and young adults. Thus, to better understand sleep seems paramount, including how to best measure it. The Pittsburgh Sleep Quality Index (PSQI) is one of the most widely used sleep measures. Some recent psychometric evidence (i.e., inconsistent dimensionality across studies) has called into question the application of this clinically developed measure. The current study sought to rigorously test the dimensionality of the measure, by comparing a psychometric application of it to a clinical application. It also tested correlates of sleep quality measured by the PSQI, including academic achievement, mental health, and substance use (alcohol and drug use) . Data were collected from 820 college students using an online computer-assisted protocol. Results from factor analyses supported a 2-factor solution for the PSQI. Findings from path analyses using scale scores based on the extracted factor structure as the independent variable provided evidence that the psychometric approach worked equally well as the clinical application using the global sleep quality risk score , providing some support for the use of a psychometric approach of the PSQI. Sleep quality scores (both scale and global sleep quality risk scores) were consistently associated with academic achievement, mental health, and substance use problems, thus providing further support on the importance of good sleep for young adults. Public Significance StatementThe current study provides support for the application and use of the Pittsburgh Sleep Quality Index (PSQI), based both on psychometric and clinimetric approaches, in understanding a number of adjustment measures (i.e., GPA, mental health problems, alcohol use, and drug use) among college students. Using the psychometric approach provides a more nuanced understanding of how subscales part of the PSQI vis-à-vis a global risk score are associated with adjustment.
