ABSTRACT
A large empirical literature in psychology has established a two-dimensional model of measuring affect (positive and negative emotion) as well as circumplex-based models. The present series of studies begins with items developed from a philosophical theory of affect, which were iteratively reduced to a 6-factor, 18-item measure of emotional well-being, which provides more arousal-based granularity of positive and negative affect. In study 1 (N = 727), using exploratory factor analysis, we found evidence for the classic two-dimensional structure of affect based on parsimony: 1) positive emotion and 2) negative emotion, in addition to a six-dimensional model closer to circumplex-based approaches based on model fit and other factor analytic criteria, consisting of: 1) cheerfulness, 2) vitality, 3) serenity, 4) sadness, 5) lethargy, and 6) stress. In study 2 (N = 667), using confirmatory factor analysis, we found that the two-factor solution provided inadequate fit, as did other prominent two-factor emotion measures, while the six-factor model provided excellent fit (CFI = .98, RMSEA = .055). The resulting measure, the Emotional State Assessment Tool (ESAT), provides a philosophically grounded, brief, versatile, and more cross-culturally sensitive measure of affect to complement existing measures of affect.

Notes
1. For other examples of collaboration between psychologists and philosophers in developing well-being measures, see, (Margolis et al., Citation2019, Citation2020).
2. Emotional state theory was developed as an account of happiness (Haybron, Citation2008), and ESAT could reasonably be regarded as a happiness scale. But the theory’s central construct, emotional well-being, is of interest regardless of one’s views about happiness (Haybron, Citation2008), and is our focus here. In recent years variants of this account of happiness have been widely endorsed in the philosophical literature (e.g., Badhwar, Citation2014; Becker, Citation2012; Besser-Jones, Citation2013; De Lazari-radek & Singer, Citation2014, p.; Haybron, Citation2020; Kauppinen, Citation2013; Klausen, Citation2015; May, Citation2015; Raibley, Citation2012; Rodogno et al., Citation2016; Rossi, Citation2018; Rossi & Tappolet, Citation2016; Sizer, Citation2010; Tiberius, Citation2018; Višak, Citation2015).
