Categorical subjective sleep predictors (i.e., Subjective total sleep time 0–3, etc.) and overall P presented only for significant Subjective total sleep outcomes (i.e., depressed mood; p < .05); overall P = p-value for Subjective total sleep time; reference group is Subjective total sleep time 6–8 h; Adj P, p-values are corrected for multiple testing with the Benjamini-Hochberg (BH) method 1) in comparisons of Subjective total sleep time 6–8 vs. the other sleep time groups; 2) in association analyses between the related outcomes (pain and mood, e.g., happy, worried) and Subjective sleep restfulness; significant associations (p < .05) are in bold
