The Everyday Wellbeing Appraisal Scale: Assessing a type of subjective well-being uniquely associated with health behavior in people with hypertension.

Everyday well-being appraisals are judgments about the goodness of recent daily life events. These appraisals are expected to be distinct from other types of well-being involving traits, affect, and psychological distress and expected to be uniquely important for understanding health behavior such as exercise, diet, and treatment adherence for people with medical conditions. To develop and test a new Everyday Wellbeing Appraisal Scale, two studies were conducted in which a total of 718 people with hypertension completed online questionnaires. In Study 1, to achieve maximum validity with the fewest number of items, an empirical analysis was used to select a set of six items with high discrimination that incorporated multiple types of response-option formats. In Study 2, the scale's unidimensional factor structure and high discrimination were confirmed, and the new scale outperformed several existing types of well-being scales in its ability to explain unique variance in health behavior criterion variables. Specifically, it explained unique variance in health behavior after controlling for a widely used measure assessing trait-level reflections of well-being, as well as measures of positive affect and two types of psychological distress. Also, when compared to the trait-level measure of well-being, the new scale demonstrated less overlap with affect and psychological distress. These results suggest that this brief, new scale is valuable for assessing a distinct construct that is especially salient for understanding health behavior.
