Positive and Negative Affect Schedule (PANAS)
The Positive Affect and Negative Affect Schedule (PANAS) is a 20-item self-report questionnaire used to measure the emotions of the respondent at the present moment or during the past few weeks. The items are grouped into the two subscales with 10 items each: positive affect and negative affect. This tool was developed by Watson, Clark, and Tellegen from the Southern Methodist University and University of Minnesota.
