Positive and Negative Affect Schedule (PANAS)
Separate positive-affect and negative-affect scores with an explicitly chosen time frame.
Questionnaire The format describes how observations are obtained, not an evidence rating.
What it measures
Two affect dimensions, not opposite ends of a single happiness scale.
What people do
The original schedule uses two ten-item mood scales rated on a 5-point scale from 1 (Very slightly or not at all) to 5 (Extremely). Instructions can specify different time frames (such as right now, past week or in general); the chosen period belongs in the methods report.
What the scores mean
Sum the ten Positive Affect items and the ten Negative Affect items separately to yield two scores, each ranging from 10 to 50. High positive affect does not mathematically require low negative affect.
This explains the logic of a score. It does not supply a test form, individual result or administration manual.
Development and versions
David Watson, Lee Anna Clark and Auke Tellegen introduced PANAS in 1988. Expanded (PANAS-X) and child versions are separate forms.
Evidence: (D. Watson et al., 1988); (Spielman et al., 2020)
Reliability and validity evidence
Inspected primary-article excerpts address factor markers, time frames and retest comparisons across seven time instructions. They do not establish that every translated or shortened version shares the same structure.
Evidence belongs to a version, sample and interpretation. Read the source notes for what was actually inspected.
Evidence: (D. Watson et al., 1988); (Spielman et al., 2020)
Where it is used
Studies separating momentary affect from more typical affect reports, while matching the instructions to the question.
Limits and common misreadings
- Activated positive feelings do not exhaust all forms of well-being.
- A momentary report and a general report are not interchangeable.
- Do not subtract the two scales automatically and call the result happiness.
Read an example
Original teaching example
A fictional performer feels enthusiastic and anxious before a concert. Treating positive and negative affect as separate dimensions allows both reports, instead of forcing a single good-or-bad mood score.
Constructed for learning; this is not a result from the instrument’s validation study.
Access and permission
Check the chosen form’s rights and translation terms with its source. The accessible article does not by itself establish blanket redistribution permission.

PubMed bibliographic record (Journal of Personality and Social Psychology, 54(6), 1063–1070) and indexed text excerpts covering the two 10-item scales, 1-to-5 rating format and time-frame instructions were inspected.
