Correspondence of motivational enhancement treatment integrity ratings among therapists, supervisors, and observers.

This study examined the correspondence of treatment integrity ratings (adherence and competence) among community program therapists, supervisors, and observers for therapists who used motivational enhancement therapy (MET) within a National Institute on Drug Abuse Clinical Trials Network protocol. The results suggested there was reasonable agreement between the three groups of raters about the presence or absence of several fundamental MET strategies. Moreover, relative to observers, therapists and supervisors were more positive in their evaluations of the therapists' MET adherence and competence. These findings underscore the need for objective monitoring of therapists' performance when using empirically supported treatments and for adequately training therapists and supervisors to evaluate their treatment implementation in community programs, and are consistent with observations that different perspectives on the therapeutic process are not interchangeable.
