Person-environment transaction underlying personality development in middle and late adulthood.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The niche-picking principle has been proposed to explain stabilization in personality development and personality continuity in adulthood. The niche-picking principle posits that the reciprocal exchange between people and their environments-person-environment transaction-serves to maintain trait continuity, thereby preserving rank-order stability of trait differences. To date, however, no longitudinal twin study has directly tested whether reciprocal effects between people and their environments contribute to trait continuity in middle and older adulthood. Using a sample of twins from the Swedish Adoption/Twin Study of Aging, we tested whether the niche-picking principle explained stability of longitudinal within-family differences in neuroticism, extraversion, and openness across two stages of adult development. Genetic simplex models that include a reciprocal effects (i.e., phenotype-environment covariance) parameter were fit to twins' longitudinal data. Results suggest that the niche-picking principle partly explains continuity of neuroticism and openness in middle adulthood whereas it partly explains continuity of neuroticism and extraversion in older adulthood. Stable genetic and unique environmental variance also explained continuity of each trait. Findings partially support lifespan developmental theories that posit that people adapt to and possibly optimize behaviors to sustain existing traits. We discuss the importance of the reciprocal exchange between people and their environments across the lifespan and how these exchanges might shift to support trait continuity.
