This study investigated the core principles in Rational Emotive Behavior Therapy (REBT) and whether targeting the cognition of demandingness was predictive of greater therapeutic change. Nine clients were randomly assigned to one of two nine-session treatment conditions. These included either REBT that targeted the irrational beliefs of demandingness (n = 3) or (2) REBT treatment as usual (TAU) (n = 6). Participants included clinically anxious adults who received psychotherapy from a metropolitan clinic that specialized in REBT. Clinical outcome was measured by the Beck Anxiety Inventory (BAI), State Trait Anxiety Inventory (STAI), Psychiatric Diagnostic Screening Questionnaire (PDSQ), and Shortened General Attitude and Belief Scale (S-GABS) during intake, fifth, and ninth sessions. Weekly therapy progress was evaluated by the Outcome Questionnaire (OQ) and Idiosyncratic Belief Scale in sessions one through nine. It was hypothesized that treatment that focused on disputing only demands would produce a greater change than REBT TAU. REBT produced a significant positive change in functioning in both the demandingness (55.56% improvement across outcome measures) and REBT TAU condition (65% improvement across outcome measures). Out of all the clients in both treatment conditions, the four clients who demonstrated largest treatment effects in measures of demandingness, showed the largest percentage of positive change in outcome measures, as opposed to other irrational beliefs. On four out of the five outcome measures, the majority of participants demonstrated a significant.
