A four-item scale measuring the momentary sense of emotional ease and comfort a consumer experiences. Two items are positively keyed (ease, comfort) and two are reverse-scored (anxious, stressed), providing a balanced assessment of the calm-distress continuum. Developed to capture the stress-reduction effects of smartphone use, the scale is applicable to any research context in which the subjective experience of comfort or emotional ease is the outcome of interest.
