This measure provides a brief self-report assessment of current or typical affective experience. The Positive and Negative Affect Schedule (PANAS) uses adjective ratings to quantify two broad dimensions of mood: positive affect and negative affect.
The instrument includes 20 items and typically takes about 4 minutes to complete. Respondents indicate the extent to which they have experienced each feeling state over a specified time frame (e.g., momentary, past few days, or in general), supporting use in clinical monitoring and research contexts. Scoring yields separate indices for positive and negative affect that can be interpreted as dimensional indicators of emotional state.
The Positive and Negative Affect Schedule (PANAS) is commonly used to track changes in affect over time, evaluate treatment-related shifts in mood, and characterize affective profiles across settings and populations. Auke Tellegen is cited among the original developers.
