Abstract
The purpose of this study was to operationalize the constructs of the Theory of Planned Behavior (TPB) to predict the sleep
intentions and behaviors of undergraduate college students attending a Midwestern University. Data collection spanned three
phases. The first phase included a semi-structured qualitative interview (n = 11), readability by Flesch-Kincaid, face and content validity by a panel of six experts. The second phase included stability
reliability by test–retest (n = 37). The final phase included construct validation applying confirmatory factor analysis, internal consistency by Cronbach’s
alpha, and predictive validity (n = 197) employing multiple regression analysis. The majority of the participants reported receiving insufficient sleep (M = 407.3 min, SD = 100.75). Multiple regression modeled perceived behavioral control, subjective norm, and attitude toward adequate sleep
behavior on behavioral intention. Collectively, the significant predictors produced an R
adjusted2 value of .362. Further specification of the model identified behavioral intention as a significant predictor of sleep behavior
(R
adjusted2 = .185). As a population, undergraduate college students are not achieving adequate sleep. The TPB was found to be a useful
framework for predicting the sleep intentions and behaviors of undergraduate students. Practical implications and recommendations
for future research are discussed.
