Introduction
The Positive and Negative Affect Schedule (PANAS) is one of the most widely used tools in affective science to assess emotional states. Developed by Watson, Clark, and Tellegen in 1988 and published by Journal of Personality and Social Psychology (The “Journal of Personality and Social Psychology” published the original study, but the questionnaire itself is not “owned” by the journal.), this 20-item questionnaire measures both positive affect (PA) and negative affect (NA). Its ease of use and adaptability make it valuable for both research and clinical applications, especially in the domains of mental health and emotional well-being.
In this article, we will delve into the PANAS questionnaire’s key features, its applications, reliability, validity, scoring method, and how it can be employed effectively for research and clinical purposes.
Key Features of the Positive and Negative Affect Schedule
Purpose and Use
The PANAS measures momentary emotional states or long-term emotional traits. It includes two primary domains:
- Positive Affect (PA): Measures emotions such as enthusiasm, alertness, and determination.
- Negative Affect (NA): Assesses emotions such as distress, fear, and guilt.
This makes the PANAS ideal for monitoring mood states and conducting emotional assessments in clinical settings.
Target Population
The PANAS targets adult patients aged 18 years and older. It is suitable for various age groups, including:
- Young Adults (18–24 years)
- Middle-Aged Adults (25–44 years)
- Older Adults (45–64 years)
- Seniors (65+ years)
Structure
The questionnaire consists of 20 items, with 10 items for Positive Affect and 10 items for Negative Affect.
Scoring Method
Respondents rate each adjective on a 5-point Likert scale, which includes:
- 1: Very slightly or not at all
- 2: A little
- 3: Moderately
- 4: Quite a bit
- 5: Extremely
The total scores for PA and NA are summed separately, each ranging from 10 to 50, with higher scores indicating stronger affect.
Domains and Sub-domains
- Domain: Mental Health
- Subdomain: Emotional States and Mood Assessment
This framework ensures that the PANAS is particularly useful for understanding mood disorders, anxiety, and emotional regulation.
Administration Format
- Digitally (Online): Through digital platforms or mobile apps.
- Paper-based: In a traditional survey format.
- Mobile App: For on-the-go assessments.
It is self-administered, meaning that no special training is required for participants to complete the questionnaire. The estimated time required to complete the PANAS is 5-10 minutes, making it a quick and efficient tool for assessing mood
Applications of the Positive and Negative Affect Schedule
The PANAS is valuable in both clinical and research settings. It is primarily used for:
- Screening: Identifying emotional states such as anxiety and depression.
- Monitoring: Tracking emotional changes over time.
- Research: Studying the impact of emotional states on behavior and health outcomes.
Languages Available
The PANAS is available in multiple languages:
- English
- Arabic
- German
- Spanish
- PortugueseÂ
- French
- And many moreÂ
Reliability and Validity
The PANAS has shown high reliability and validity in multiple studies. The Cronbach’s alpha for Positive Affect (PA) ranges from 0.86 to 0.90, while for Negative Affect (NA), it ranges from 0.84 to 0.87. These values demonstrate the questionnaire’s strong internal consistency. It has been cited in over 38,656 studies, confirming its robustness and clinical utility.
Limitations and Considerations
While the PANAS is an excellent tool, it does have some limitations:
- Self-report measure: Responses are based on personal perception, which can introduce bias.
- Cultural Bias: Emotional experiences can differ across cultures, which may affect the accuracy of the results in diverse populations.
- Social Desirability Bias: Respondents may provide answers that they perceive to be more socially acceptable rather than truthful.

Frequently Asked Questions (FAQ)
- How accurate is the PANAS in measuring emotional states?
The PANAS is highly reliable, with Cronbach’s alpha values indicating strong internal consistency for both PA and NA subscales. - Can the PANAS be used for clinical diagnosis?
While the PANAS is useful for screening and monitoring emotional states, it is not intended to diagnose mental health disorders on its own. - Is the PANAS free to use?
Yes, the PANAS is free for research and clinical use. However, commercial use may require permission (APA holds copyright, but authors permit academic use)
A word from ResRef
The PANAS questionnaire remains a cornerstone in affective science, offering a robust and efficient tool for measuring emotional states. Its brevity and adaptability make it ideal for both research and clinical use, though practitioners should consider cultural and contextual factors when interpreting scores. Continued validation in diverse populations will further enhance its global applicability.
