Enhancing Treatment Fidelity in Psychotherapy Research: Novel Approach to Measure the Components of Cognitive Behavioural Therapy for Relapse Prevention in First-Episode Psychosis

Abstract

This study described the development of a brief, reliable and internally consistent measure to determine both treatment fidelity and the therapy components implemented throughout the intervention. This methodology can be potentially useful to determine those components related to therapeutic change.

Implementation and development of early intervention in psychosis services in Italy: a national survey promoted by the Associazione Italiana Interventi Precoci nelle Psicosi

Development and evaluation of a treatment fidelity instrument for family‐based treatment of adolescent anorexia nervosa

“…While IRR scores may appear low in this study, they are consistent with the range of scores found in other psychometric analyses of fidelity instruments, highlighting the greater difficulty in achieving agreement on fidelity that encompasses competency ratings, 7,35,36 than adherence ratings. 37,38 Inconsistency in rater agreement likely reflects differences in raters' conceptualization of competence, the aspects of the intervention emphasized and challenges in operationalizing competence. 5 Fidelity evaluators in this study identified these issues as core challenges in their efforts.…”

Assessing fidelity to integrated motivational interviewing and CBT therapy for psychosis and substance use: the MI-CBT fidelity scale (MI-CTS)

“…the Cognitive Therapy Scale Revised (Blackburn et al, 2000) and the Cognitive Therapy Scale for Psychosis (CTS-Psy; Haddock et al, 2001). Other therapy fidelity scales have also been used for assessing CBT delivery in psychosis (Evans et al, 1984;Devane et al, 1998;Startup et al, 2002;Rollinson et al, 2008;Barber et al, 2003;Alvarez-Jimenez et al, 2008).…”
