q2 · i? · review · r2

Quasi-experiment with business-as-usual control of 321 UK undergraduates receiving four months of in-person coaching informed by the GROW model and the Demands Affordances and Transactional model. The review reports the small decrease and the null control-group change.

"Coaching produced significant reductions in conscientiousness between pre-intervention and post-intervention. This decrease was small (i.e., 0.06 points on a 1–5 scale). For the control group, there was no significant change in trait conscientiousness between the same two time points"
