The VAMS is a reliable and valid measure of eight specific mood states: Afraid, Confused, Sad, Angry, Energetic, Tired, Happy, and Tense. This simple, brief test places minimal cognitive or linguistic demands on the respondent and is appropriate for neurologically impaired individuals or those who are unable to complete more verbally or cognitively demanding instruments. Test materials include the Professional Manual, the VAMS Response Booklet, and a metric ruler. A pen or pencil is also required for administration.
The scales have a “neutral” schematic face (and accompanying word) at the top of a 100 mm vertical line and a specific “mood” face (and word) at the bottom of the line.
