1. In-session outcomes. Using the videotapes, observer-based videoanalyses will be conducted: (a) Do the resource priming conditions show comparable observer-based therapist's adherence in comparison to the adherence priming condition (Zinbarg et al., 2007)? (b) Do the resource priming conditions show more resource activating micro interventions than the adherence priming condition (ROMA; Flückiger & Grosse Holtforth, 2008a/b)? (c) Are the in-session processes predictors and mediators of session and therapy outcomes (Flückiger et al., 2009; Flückiger et al., 2013)?
