The Positive and Negative Affect Schedule (PANAS) is a self-report questionnaire that assesses positive and negative affect. It was developed by researchers from the University of Minnesota and Southern Methodist University in 1988. The PANAS consists of 20 items, with participants rating their experience of 20 emotions on a 5-point scale, reflecting either a recent timeframe or a general feeling. The Positive Affect (PA) and Negative Affect (NA) scores are then summed separately, with higher scores indicating more positive or negative emotions, respectively. The PANAS has been found to be a reliable and valid instrument in the assessment of positive and negative emotions and is useful for tracking changes in emotional states over time.

The PANAS is a self-report questionnaire
The Positive and Negative Affect Schedule (PANAS) is a self-report questionnaire that assesses an individual's positive and negative affect. It was developed in 1988 by researchers from the University of Minnesota and Southern Methodist University. The questionnaire consists of 20 items that participants rate on a 5-point scale, ranging from "very slightly" to "extremely". The items are designed to measure the extent to which an individual has experienced different emotions during a given timeframe, which can be either recent or general feelings. The timeframe used will determine whether the questionnaire provides a snapshot of the participant's current affective state or an overview of their typical emotional responses.
The PANAS is a useful tool for practitioners and therapists who want to identify client strengths and symptoms of well-being. It can also be used to track changes in clients' emotions from week to week and can be a helpful indicator of the effects of therapy sessions and other positive psychological interventions. The questionnaire generally takes around 5 to 10 minutes to complete, making it convenient for both clinical and research settings.
To calculate PANAS scores, the 20 items are divided into two scales: the Positive Affect (PA) and the Negative Affect (NA). The PA scale measures pleasurable engagement with the environment, while the NA scale reflects a dimension of general distress, including negative states such as anger, guilt, or anxiety. The scores for each scale are calculated by summing the ratings for each set of items, with higher scores indicating higher levels of engagement within that particular affect. The potential scores for each scale range from 10 to 50, with lower scores representing lower levels of positive or negative affect.
While the PANAS has been found to have good internal consistency reliability, it is important to note that it is not a diagnostic instrument and does not encompass higher-order mood states. As a self-report measure, it can also be challenging to assess people's moods accurately, as individuals may overstate or understate their experiences. Despite these limitations, the PANAS remains a valuable tool for assessing and tracking positive and negative emotions.

It measures both positive and negative affect
The Positive and Negative Affect Schedule (PANAS) is a self-report questionnaire that measures both positive and negative affect. It was developed in 1988 by researchers from the University of Minnesota and Southern Methodist University. The PANAS consists of two 10-item scales, with a total of 20 items, that assess positive affect (PA) and negative affect (NA). PA is associated with pleasurable engagement with the environment, while NA reflects a dimension of general distress summarising a variety of negative states such as anger, guilt, or anxiety.
The PANAS procedure involves participants rating their experience of 20 emotions on a 5-point scale, reflecting either a recent timeframe or a general feeling. This approach provides a snapshot of the participant’s current affective state or an overview of their typical emotional responses, depending on the timeframe used. The PANAS questionnaire generally takes around 5 to 10 minutes to complete, as participants quickly rate each item based on how they have felt recently. This short timeframe makes it convenient for both clinical and research settings where time-efficient assessments are needed.
The PANAS score is separated into the Positive Affect (PA) and Negative Affect (NA) scores, with a higher score indicating more positive or negative affect respectively. Scores can range from 10 to 50 for both the Positive and Negative Affect, with the lower scores representing lower levels of Positive/Negative Affect and higher scores representing higher levels. The PANAS has been reported to have very good internal consistency reliability, with alphas ranging from 0.85 to 0.90 for Positive Affect and from 0.84 to 0.87 for Negative Affect.
Since its creation, the PANAS has spawned several variations such as the PANAS-X (an extended version with 60 items), PANAS-C (a 27-item PANAS for use with children), and I-PANAS-SF (a 10-item PANAS optimised for international use). The PANAS-X includes eight different sets of temporal instructions intended to measure affects ranging from transitory emotional states to relatively stable, enduring personality traits. The PANAS-X measures both Positive Affect (PA) and Negative Affect (NA), as well as 11 primary affects, including fear, sadness, guilt, hostility, shyness, fatigue, surprise, joviality, self-assurance, attentiveness, and serenity.

The PANAS questionnaire generally takes around 5 to 10 minutes to complete, as participants quickly rate each item based on how they have felt recently. This short timeframe makes it convenient for both clinical and research settings where time-efficient assessments are needed.
To calculate PANAS scores, participants rate each of the 20 emotion-related items on a 5-point scale from “very slightly” to “extremely.” The Positive Affect and Negative Affect scores are then summed separately, with higher scores in each category indicating a greater intensity of positive or negative emotions, respectively. Scores can range from 10 to 50 for both the Positive and Negative Affect, with the lower scores representing lower levels of Positive/Negative Affect and higher scores representing higher levels.
The PANAS is a useful tool for therapists who are interested in tracking changes in positive and negative emotions for clients from week to week as they engage in day-to-day life. It is sensitive to momentary changes in affect and can be used to chart the immediate effects of therapy sessions as well as outcomes associated with positive psychological interventions, exercises, or activities.

It takes 5-10 minutes to complete
The Positive and Negative Affect Schedule (PANAS) is a self-report questionnaire that takes around 5 to 10 minutes to complete. It consists of two 10-item scales to measure both positive and negative affect, with 20 items in total. Each item is rated on a 5-point verbal frequency scale of 1 (not at all) to 5 (very much). The PANAS was developed in 1988 by researchers from the University of Minnesota and Southern Methodist University.
Participants are asked to rate their experience of 20 emotions, which can be done in relation to a recent timeframe or a general feeling. This provides a snapshot of the participant’s current affective state or an overview of their typical emotional responses. The PANAS is designed to be sensitive to momentary changes in affect, and participants are instructed to indicate to what extent they feel these emotions at the moment or how they felt over the past week.
The PANAS score is separated into Positive Affect (PA) and Negative Affect (NA) scores, with higher scores indicating more positive or negative affect respectively. Scores can range from 10 to 50 for each scale. Positive Affect is associated with pleasurable engagement with the environment, while Negative Affect reflects a dimension of general distress, summarising a variety of negative states such as anger, guilt, or anxiety.
There are several variations of the PANAS, including the PANAS-X, an extended version with 60 items, and the PANAS-C, a 27-item version for use with children. The PANAS-X includes eight different sets of temporal instructions intended to measure affects ranging from transitory emotional states to relatively stable personality traits.

The PANAS-X is an extended version with 60 items
The Positive and Negative Affect Schedule (PANAS) is a self-report questionnaire that consists of two 10-item scales to measure both positive and negative affect. The PANAS was developed by researchers from the University of Minnesota and Southern Methodist University in 1988.
In 1994, an expanded form of the PANAS, called the PANAS-X, was developed by Watson and Clark. The PANAS-X is an extended version with 60 items that can be completed in 10 minutes or less. The PANAS-X incorporates the original higher-order dimensions specified in the PANAS, as well as the measures of 11 lower-order emotional states. These 11 primary affects are: fear, sadness, guilt, hostility, shyness, fatigue, surprise, joviality, self-assurance, attentiveness, and serenity.
The 11 affective states are broken down into three main categories: basic negative emotion scales consisting of fear, hostility, guilt, and sadness; basic positive emotion scales consisting of joviality, self-assurance, and attentiveness; and other affective states consisting of shyness, fatigue, serenity, and surprise. Through extensive analyses, all eleven affective states, except for surprise, were shown to be valid measures that assess how an individual's emotional states fluctuate over time.
The PANAS-X includes eight different sets of temporal instructions intended to measure affects ranging from transitory emotional states to longer-lasting mood states and relatively stable, enduring personality traits. The eight different temporal instructions are: 'Right Now', 'Today', 'Past Few Days', 'Past Week', 'Past Few Weeks', 'Past Month', 'Past Year', and 'In General'.
The PANAS-X is a useful tool for therapists interested in tracking changes in positive and negative emotions for clients. It is sensitive to momentary changes in affect and can be used to chart the immediate effects of therapy sessions, as well as outcomes associated with positive psychological interventions, exercises, or activities.
