Sleeping 7 to 8 hours on a daily basis is an essential element of optimal health. 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 were collected from cross-sectional convenience samples over three phases. Phase I encompassed collecting qualitative data (n=11) for instrument item generation. Phase II entailed collecting data (n=37) for reliability testing. Phase III data (n=197) assessed the efficacy of the instrument to predict the sleep intentions and behaviors of the sample. For phase III, a power analysis was conducted to determine a sufficient sample size (α = 0.05, β = 0.80, ρ = 0.20). Instrumentation included readability by Flesch-Kincaid ease and grade level tests, face and content validity by a panel of six experts, reliability by test-retest, construct validation applying confirmatory factor analysis, and internal consistency by Cronbach's alpha. Multiple linear regression modeled the predictors of perceived behavioral control (β =0.457, t=7.882, p < 0.001), subjective norm (β =0.179, t=3.000, p = 0.003), and attitude toward the behavior (β=0.231, t=3.865, p < 0.001) on behavioral intention. Collectively, the significant predictors produced an R2 adjustedvalue of 0.362 (F (3, 196) = 38.133, p < 0.001), suggesting the model accounted for 36.2% of the variance in the behavioral intention to obtain adequate sleep in the sample of participants. Binary logistic regression was employed to model adequate sleep behavior. Behavioral intention (B=0.067, Wald χ 2 (1) = 4.440, p = 0.036) and sleep hygiene (B=0.055, Wald (χ 2 (1) = 10.006, p = 0.002) were found to be significant predictors of sleep behavior; conversely, gender was not significant in the prediction of sleep behavior (B=0.475, Wald χ 2 (1) = 1.670, p = 0.196). Analysis revealed that for each one unit increase in behavioral intention the odds of obtaining adequate sleep increased by 7.0%. Similarly, for each one unit increase in sleep hygiene the odds of obtaining adequate sleep behavior increased by 5.7%. The TpB was found to be a useful framework for designing health promotion and education interventions for improving the sleep intentions and behaviors of undergraduate students. The results of this investigation provided a valid and reliable instrument for application in the measurement of TpB based interventions targeting undergraduate sleep health.
