Description

Background:
The Positive and Negative Affect Scale (PANAS) is based upon research demonstrating that self-reported mood states can be effectively classified on these two dimensions (Watson, Clark and Tellegen 1988). Each PANAS scale comprises ten specific mood-related adjectives, rated on five-point scales, of frequency over a two-week period. Both PANAS scales have good reliability (Watson, Clark and Tellegen 1988), are correlated with other indicators of affect (Watson, Clark and Tellegen 1988) and are sensitive to changes over time (Watson, Clark and Tellegen 1988).
