Abstract

The properties of the 17-item Mentalization-Based Treatment Adherence and Competence Scale (MBT-ACS) were investigated in a reliability study in which 18 psychotherapy sessions, comprising two sessions by nine different therapists, were rated by seven different raters. The overall reliabilities for adherence and competence for seven raters were high, .84 and .88 respectively. The level of reliability declined by number of raters but was still acceptable for two raters (.60 and .68). The reliabilities for the various items differed. The MBT-ACS was found to be an appropriate rating measure for treatment fidelity and useful for the purposes of quality control and supervision. The reliability may be enhanced by redefining some items and reducing their numbers.

本研究探究共有17題的「以心智化為基礎的治療固著性與能力量表(MBT-ACS)」 信度。研究是蒐集9位不同治療師各兩次的治療歷程,共計有18次治療,由7位 不同的評量者評分。七位評分者整體的固著性和能力信度都很高,分別為.84 和.88。信度係數隨著評分者人數的減少而遞減,不過即使是僅有兩位評分者的 信度也還在可接受範圍(.60 和.68)。不同題項的信度係數也有所不同。本量 表可用來測量治療的忠誠度,且可有效用來作為品質管制與督導之用。若是重 新定義一些題項以及減少量表題數,應可增加信度。

Sono state valutate le proprietà del Mentalization-Based Treatment Adherence and Competence Scale (MBT-ACS), strumento a 17-item, in uno studio reliability dove sono state siglate 18 sedute di psicoterapia, che comprendevano due sedute di nove terapeuti diversi, da sette differenti siglatori.

L'affidabilità complessiva per l'aderenza e la competenza dei sette valutatori era alta, .84 e .88 rispettivamente. Il livello di affidabilità è diminuito dal numero di valutatori, ma era ancora accettabile con due valutatori (.60 e .68). Differiva l'affidabilità per i vari item. La MBT-ACS è apparsa uno strumento di valutazione adeguato per la fedeltà al trattamento e utile ai fini del controllo di qualità e supervisione. L'affidabilità può essere migliorata, ridefinendo alcuni oggetti e ridurre il loro numero.

Die Eigenschaften der 17-Item Mentalization-Based Treatment Adherence and Competence Scale (MBT-ACS) wurden in einer Reliabilitätsstudie untersucht, in der 18 Psychotherapiesitzungen, bestehend aus jeweils zwei Sitzungen bei neun verschiedenen Therapeuten von sieben verschiedenen Ratern eingeschätzt wurden. Die globalen Reliabilitäten der sieben Rater für Adhärenz und Kompetenz waren hoch, .84 bzw.88. Das Ausmaß an Reliabilität sank mit abnehmender Raterzahl, war jedoch auch für zwei Rater akzeptabel (.60 und .68). Die Reliabilität unterschied sich für die unterschiedlichen Items. Die MBT-ACS erwies sich als angemessenes Ratinginstrument der Verfahrenstreue und als nützlich für den Zweck der Qualitätskontrolle und Supervision. Die Reliabilität könnte durch die Umdefinierung einzelner Items und durch die Reduktion der Item Anzahl erhöht werden.

As propriedades dos 17 itens da Escala de Adesão e Competência do Tratamento Baseado na Mentalização (MBT-ACS) foram investigadas num estudo de fidelidade, em que 18 sessões de psicoterapia, incluindo duas sessões de nove terapeutas diferentes, foram classificadas por sete avaliadores. Os valores de fidelidade global para a aderência e competência dos sete avaliadores foram elevados, .84 e .88 respetivamente. O nível de fidelidade foi diferente para os vários itens. Verificou-se que o MBT-ACS é uma medida apropriada para a fidelidade do tratamento e adequada para propósitos de controlo de qualidade e supervisão. A fidelidade pode ser aumentada pela pela redução do número de itens e sua redefinição.
