![]() ![]() Examination of other analogous PSQI and sleep diary components showed low to moderate convergent validity: sleep latency (r = 0.70), wake after sleep onset (r = 0.37), sleep duration (r = 0.51), and sleep efficiency (r = -0.32). The PSQI global score demonstrated good divergent validity with measures of excessive daytime sleepiness (r = 0.18), circadian preference (r = -0.08), alcohol (r = 0.08) and marijuana (r = 0.05) abuse scales, and poor divergent validity with depression (r = 0.48), anxiety (r = 0.40), and perceived stress (r = 0.33). The PSQI global score had only moderate convergent validity with sleep diary sleep efficiency (prospective global measure of sleep continuity r = 0.53), the Insomnia Severity Index (r = 0.63), and fatigue (r = 0.44).
