B, unstandardized coefficient of beta; Bz, unstandardized coefficient of beta calculated w/standardized outcome/dependent variable; SEB, standardized error of the coefficient; β, standardized coefficient of beta indicating the extent to which a one standard deviation change in the independent variable relates to a one standard deviation change in the outcome; p, p value. SDs in the PSG sample (n = 172) as follows: CTQSD = 5.37, Delta%SD = 7.58, REM DensitySD = 4.63.
Note: bolded p < .05 and survived Benjamini-Hochberg correction for multiple comparisons.
