The Positive and Negative Affect Schedule (PANAS) is a psychological tool designed to measure two key aspects of emotional experience: positive affect (PA) and negative affect (NA). It requires individuals to rate the intensity of positive emotions (e.g., joy, excitement) and negative emotions (e.g., fear, sadness) experienced over a set time period. This assessment provides valuable insights into mood states and emotional wellbeing, and is widely recognized for its reliability and validity across diverse populations and settings.
