Prospective associations of @entity258 with first onsets of XXXX : Results from a 10-wave latent trait-state modeling study.

@entity308 and @entity148 co-occur at high rates and can be difficult to distinguish from one another. Cross-sectional evidence has demonstrated that whereas all these disorders are characterized by high negative emotion, low positive emotion shows specificity in its associations with @entity308 , @entity148 , and possibly generalized @entity148 . However, it remains unknown whether @entity258 , a personality trait characterized by the tendency to experience low positive emotion over time, prospectively marks risk for the initial development of these disorders. We aimed to help address this gap. Each year for up to 10 waves, @entity1 (n = 627, mean age = 17 years at baseline) completed self-report measures of mood and personality and a structured clinical interview. A latent trait-state decomposition technique was used to model positive emotionality and related personality traits over the first 3 years of the study. Survival analyses were used to test the prospective associations of @entity258 with first onsets of disorders over the subsequent 6-year follow-up among @entity1 with no relevant disorder history. The results showed that @entity258 was a risk marker for @entity308 , @entity148 , and generalized @entity148 , although evidence for its specificity to these disorders versus the remaining @entity148 was inconclusive. Additional analyses revealed that the risk effects were largely accounted for by the overlap of @entity258 with @entity663 . The implications for understanding the role of positive emotionality in @entity308 and @entity148 are discussed.
