Note. N = 92. Level 1 observations = 1,709 person-days. Unstandardized coefficients. Gender (men = 1, women = 0). The test for orthogonal day of the week indicators represent that day’s effect compared to the reference day, Sunday. Day of the week and elapsed day also had direct paths to the affect-related variables at Level 1 but were but were omitted for clarity. At L1, the residuals of the affect variables were allowed to covary. At L2, gender and the affect variables were allowed to covary.
