Steel, P., Schmidt, J., & Shultz, J. (2008) examine the relationship between personality and subjective well-being (SWB). Previous meta-analyses suggested that personality traits are strong predictors of SWB, but results were moderate. The authors argue that this is due to the "commensurability problem," where different measures are mixed in analyses. They focus on individual personality measures (e.g., NEO) and SWB categories (e.g., Life Satisfaction) and use a multivariate approach to assess variance explained by personality traits. Results show that the relationship between personality and SWB is much stronger than previously indicated, with up to 41% or 63% of SWB variance explained by personality. The authors emphasize the need to account for scale differences in future meta-analyses. The study highlights that personality traits like Neuroticism and Extraversion are closely related to SWB components such as negative and positive affect. Genetic research suggests that long-term SWB is largely determined by personality traits, and that situational factors may weaken the relationship between personality and SWB. However, job satisfaction is more situation-specific and less strongly related to personality than other SWB dimensions. The authors also note that the commensurability problem affects meta-analyses, as different personality and SWB measures may not be comparable. They suggest using single scales to improve accuracy and reduce bias. The study concludes that personality traits significantly influence SWB, and that future research should address scale differences to improve the accuracy of meta-analytic findings.Steel, P., Schmidt, J., & Shultz, J.
