Evaluación de la Competencia Terapéutica: Consistencia Interna y Acuerdo Inter-Jueces de la Escala de Terapia Cognitiva (CTS)

Having reliable instruments to measure the competence of therapists in the context of cognitive-behavioral therapy is a  tool of great clinical and empirical value. The Cognitive Therapy Scale (CTS) is one of the scales most widely used to measure therapeutic competence. In the international arena, there are few antecedents that have been proposed to investigate their validity and reliability, and this is still a controversial issue, particularly inter-judge reliability. In addition to the above, there is no research of this type in Argentina, which is why the main objective of this work was to investigate the reliability of the CTS scale. For this, a simple of 10 expert judges was formed, who, through the CTS, evaluated the performance presented by different therapists (n = 4) during the development of one session. The results allowed to conclude that it is a reliable instrument. In effect, an  optimal internal consistency was observed, both in the item- otal correlation and in the Cronbach alpha coefficient. Likewise, in general, a good consistency was observed in the scores given by the different professionals. The data presented in this research support the use of the scale in the context of Argentina and allow us to point out that the CTS is a reliable scale.
