“…Previous research on ISTDP has also indicated that a high degree of MUCE in treatment (i.e., an “unlocking of the unconscious”) is associated with better outcome in mixed patient samples (Johansson, Town, & Abbass, ; Town, Abbass, & Bernier, ). Because a core feature of GAD seems to be avoidance of negative emotions triggered in interpersonal contexts (Behar, DiMarco, Hekler, Mohlman, & Staples, ; Timulak & McElvaney, ), and some research suggest that emotional experiencing reduces GAD symptoms (e.g., Sugiura & Sugiura, ), activating and processing emotional states within therapy sessions may be particularly important in this population. Thus, for this study, we hypothesize that a higher degree of MUCE in treatment will be associated with greater symptom reduction for GAD patients receiving ISTDP.…”
