Subclaims¶

q2 i? Longitudinal studies document personality development over the lifespan, and a meta-analysis of 207 studies found robust neuroticism reductions after psychotherapy and observable conscientiousness increases. → Hayley K. Jach 2023

Evidence¶

Hayley K. Jach 2023¶

Hayley K. Jach, Lisa Bardach, Kou Murayama. (2023). How Personality Matters for Education Research. Educational Psychology Review. https://doi.org/10.1007/s10648-023-09807-4

q2 · i? · review · r2

The review reports, citing Roberts et al. (2017), a meta-analysis of 207 studies showing "robust reductions in neuroticism following psychotherapy" and observable conscientiousness increases; the review narrates rather than re-analyses this evidence.

"in a systematic review and meta-analysis, Roberts and colleagues (Roberts et al., 2017) compiled the results from 207 studies and concluded that there were robust reductions in neuroticism following psychotherapy, in addition to observable increases in conscientiousness"

Discussion¶

Learner Variables¶

• Personality Traits — outcome: instruction changes it

Related Claims¶

• Behavior activation interventions show a dose-response pattern — completing more conscientiousness challenges produced larger increases — but one behavior activation trial found no significant change — a narrower finding that bears on this claim
• Funnel plot asymmetry for openness, extraversion, and neuroticism appears attributable to reasons other than publication bias — related
