Note. The sample sizes mostly varied because competence is not rated if items comprising competence scores did not occur. The sample sizes ranged from a minimum of 108 for advanced MET competence and a maximum of 194;

Within therapist % denotes the percentage of variability in a given outcome at the client level or within therapists. Between therapist % denotes the percentage of variability in a given outcome at the therapist level or between therapists.
