The POMS consists of 72 adjectives commonly used to describe momentary mood states. Participants rate from 0 (not at all) to 5 (extremely) the extent to which each adjective describes how they feel at that moment. The items on the POMS have been factor analyzed to yield eight mood state scales: Anger, Anxiety, Confusion, Depression, Elation, Fatigue, Friendliness, and Vigor. In addition, the POMS has two intuitively derived scales: Arousal ([Anxiety + Vigor] − [Fatigue + Confusion]) and Positive Mood (Elation − Depression).
