Moderating effect of subjective cognitive concerns (top quintile [high concerns] vs. the bottom 3 [low concerns]) on the relationship between sleep symptomatology and detection speed scores. Higher detection speed scores indicate superior psychomotor function. The model adjusts for age, sex, education, depressive symptoms, anxiety symptoms, BMI, smoking, diabetes, and hypertension. No sleep symptomatology, normal scores on the PSQI, ISI, and ESS; Moderate sleep symptomatology, abnormal sleep on one of three sleep questionnaires; High sleep symptomatology, abnormal sleep on at least two of the three sleep questionnaires.
