The study investigated the extent to which common factors (CF) interventions are found within the training recording of cognitive behavior therapies. Some scholars have proposed that effective psychotherapy can be accounted for by Common Factors that exist across all psychotherapies that work. This study aims to see if CF interventions are found within cognitive behavior therapies. To discover the extent to which CF interventions are found within cognitive behavior therapies, we asked graduate students in a psychotherapy course who were assigned to watch training sessions of CBT sessions and instructed to rate the therapists’ behaviors using the Multi-Theoretical List Psychotherapeutic Interventions (MULTI) scale. The MULTI includes subscales that include the therapists' behaviors identified with Common Factors, Psychodynamic, Interpersonal therapy, Person-Centered (PC) Therapy, Behavior Therapy, Cognitive Behavior Therapy, and Dialectic Behavior Therapy. Because the students’ ratings on the MULTI were nested with therapists, within sessions, and within raters, a mixed models’ analysis was used to determine if the CF MULTI subscale were significant across student scores across tapes, therapists, and type of therapy. Before MULTI subscales were loaded, estimates of covariance parameters were checked. It was found that Beck’s Cognitive Therapy (CT), Motivational Enhancement (ME), Rational Emotive Behavioral Therapy (REBT), Schema-Focused Cognitive Therapy (SFCT), and General Cognitive Behavioral therapy (GCBT) all had significant ratings of CF MULTI scores. Social Problem Solving Therapy (SPS) and SFCT had significant differences in PD MULTI scores
