One frequently used measure for general affective states is the Positive and Negative Affect Schedule (PANAS). Participants completing the PANAS are asked to rate the extent to which they experienced each out of 20 emotions on a 5-point Likert Scale ranging from "very slightly" to "very much".

What is the best way to measure emotion?

Emotions are physical and instinctive, instantly prompting bodily reactions to threat, reward, and everything in between. The bodily reactions can be measured objectively by pupil dilation (eye tracking), skin conductance (EDA/GSR), brain activity (EEG, fMRI), heart rate (ECG), and facial expressions.

How are moods measured?

The simplest method for mood tracking is through a diary or chart where you record your mood on a scale and optionally provide additional notes. You can then use this log to understand your mood changes over time, search for patterns, and implement changes to improve your mood.
