CLEAR ANSWERS TO COMMON QUESTIONS

Frequently Asked Questions

What does this questionnaire measure?
It measures three core dimensions of current affect: high-energy positive feelings, low-activity negative feelings, and tension. Scores reflect the intensity of each dimension at the time of completion.
How should items be answered?
Rate each statement based on how it feels right now, not how it usually feels. Choose the option that best matches the current moment.
How long does it take, and how many items are included?
The questionnaire includes 15 items and typically takes about 3 minutes to complete.
How should results be interpreted?
Higher scores indicate stronger presence of that affective dimension. Results describe current state and are intended for screening or tracking, not as a standalone diagnosis.
When is it appropriate to use this questionnaire?
It is suitable when a brief snapshot of emotional background is needed, including counseling sessions, repeated monitoring, and research contexts. It can be repeated to observe changes over time.
WHAT THE TEST MEASURES
About This Assessment
Self-Report Methodology of Core Affect, EmoS-15 Test

Core Affect Self-Report Measure (EmoS-15) Test - Symptoms and Signs

This measure assesses current core affect through brief self-report ratings of emotional experience. The Core Affect Self-Report Measure (EmoS-15) is intended to provide a snapshot of momentary affective tone along basic dimensions that can be useful for clinical monitoring and research applications.

The instrument includes 15 items and typically takes about 3 minutes to complete. Developed by James A. Russell, the Core Affect Self-Report Measure (EmoS-15) can be administered repeatedly to track short-term changes in affect, with interpretation generally focusing on the pattern and relative intensity of endorsed affective states.
