“…In precision medicine, a more important part is the interplay between the two: As the result of exposure-based treatment (vs. nonexposure therapy), those with highest trait-like scores on avoidance ( higher between-individuals levels), will also show larger state-like reductions ( lower within-individual levels) in it, which in turn predict greater symptom reduction (as in the moderated-mediation model of Hesser et al, 2018). Thus, it matters not only where you come from (your trait-like characteristics), but also where you are going and which state-like changes you display in the course of treatment (Zilcha-Mano & Fisher, in press). - A complementary effect (capitalizing on strength, e.g., Cheavens et al, 2012): When the two components run in the same direction.
