A 50-item self-report survey, the Amsterdam Resting-State Questionnaire (ARSQ), was developed to measure cognition during rest. Based on data from 813 participants after five minutes of eyes-closed rest at home, factor analysis identified seven dimensions of resting-state cognition: Discontinuity of Mind, Theory of Mind, Self, Planning, Sleepiness, Comfort, and Somatic Awareness. The structure of cognition was similar during resting-state fMRI and EEG, with high test-retest correlations. Mental health correlated positively with Comfort and negatively with Discontinuity of Mind. Sleepiness may partially explain a resting-state EEG profile previously linked to Alzheimer's disease. The ARSQ provides information about cognitive phenotypes for research on neural correlates of resting-state cognition.
