Competing Models of the Structure of Subjective Well-Being: Have All Won and Must All Have Prizes?

Objective: The tripartite model of subjective well-being (SWB) posits three components: positive affect, negative affect, and life satisfaction. The fundamental issue regarding the structure of SWB and the meaning of the general SWB factor remains unresolved.

Methods: Across three studies and six samples (total N = 9304), we evaluated competing models of SWB and tested the criterion-related validity of SWB components operationalized within different models. In addition to a standard confirmatory factor analysis (CFA) and bifactor-CFA, we used exploratory structural equation modeling (ESEM) and bifactor-ESEM approaches. Latent factor models were applied to examine the nomological network of SWB in relation to several external criteria (e.g., positive expectations, depression, and anxiety).

Results: We found evidence supporting the three-factor and bifactor-ESEM models of SWB. The meaning and interpretability of the general and specific factors of SWB were found to depend on the indicators used to assess affective well-being. Several issues concerning the bifactor-CFA model were identified. Both the general and specific factors of SWB exhibited meaningful and interpretable nomological networks.

Conclusions: The structure of SWB, the value of incorporating a general factor, and the nature of general and specific SWB factors depend on the instruments used to measure SWB.
