The Seity Check-In: A novel tool for assessing momentary well-being.

Area of Science:

• Psychological assessment
• Well-being research

Background:

• Momentary well-being assessment is crucial for understanding psychological states.
• Existing measures may impose significant cognitive demands.
• There is a need for brief, multidimensional well-being instruments.

Purpose of the Study:

• To introduce and validate the Seity Check-In (SCI), a novel measure of momentary well-being.
• To assess the hedonic and eudaimonic components of well-being.
• To evaluate the SCI's psychometric properties, including validity and reliability.

Main Methods:

• Development of the Seity Check-In (SCI) with four dimensions: energy, direction, belonging, and joy.
• Administration of the SCI using a simple emoji-based rating scale.
• Psychometric analysis involving 564 participants, including criterion and construct validity assessments.
• Corroboration with open-ended mood descriptions.

Main Results:

• The SCI demonstrated high correlations with established well-being measures (r = .84–.86), supporting criterion validity.
• Each SCI dimension showed high correlations with corresponding established scales (r = .80–.85), supporting construct validity.
• The formative psychometric model indicated that the four dimensions contribute directly to overall well-being.

Conclusions:

• The Seity Check-In (SCI) is a psychometrically sound and multidimensional measure of momentary well-being.
• The SCI's minimal cognitive load and brief administration time make it suitable for applied settings.
• The SCI offers considerable utility for researchers and practitioners assessing well-being.
