General Description

The PS-6 is a self-report measure of morningness. It comprises 6 items which evaluates two factors: “best prepared” for activity (3 items) and morning activity (3 items). Responses are made using a 5-point Likert scale (1 = much earlier than most people; 5 = much later than most people). Low scores on the PS-6 denote morningness, whereas higher scores represent more evening preferences.
