Measuring the poles of negative and positive mood using the Positive Affect Negative Affect Schedule and Activation...

The Positive Affect Negative Affect Schedule (PANAS) has become one of the most widely used measures of mood. It was developed from research using responses to adjective checklists as empirical evidence for the two independent, bipolar factor model of mood. However, when scores on the PANAS were factor analyzed with those from another mood checklist, Thayer's Activation Deactivation Adjective Check List, the PANAS represented only half of the model proposed by Watson and Tellegen (1985) by not containing adjectives representing the lower poles of positive and negative affect.
