This item has been modified from the original to redact the signature present.The aim of this analogue study was to experimentally manipulate the match between psychotherapist presentation of change mechanisms when presenting a treatment rationale with participant mechanism expectations to examine the impact of matching on therapy perceptions. Participants viewed a video of a therapist presenting a treatment rationale and were randomized to hear a change rationale that either matched, did not match, or remained neutral relative to their expectations. Participants then completed measures of therapy perceptions. A series of one-way ANOVA tests were conducted to compare differences across process measures between groups. Results suggested that presentation of a change mechanism may improve some perceptions of the therapy, regardless of whether it matched expectations, but only when there is accurate recall of the change mechanism.enPlan Bs (project-based master's degrees)Master of Arts in Psychological ScienceMaster of ArtsDepartment of PsychologyCollege of Education and Human Service ProfessionsUniversity of Minnesota DuluthClinical Counseling trackScholarly Text or Essay
