La persona del terapeuta: Validación española del Cuestionario de Evaluación del Estilo Personal del Terapeuta (EPT-C)

The person of the therapist: Spanish validation of the Personal Style of the Therapist Questionnaire (PST-Q) . The Personal Style of the Therapist Questionnaire (PST-Q) is an instrument with more than 20 years of theoretical and empirical developments at the international scenario, especially in Latin America. The main goal of the study was to provide preliminary evidence on its psychometric properties and factorial structure in a sample of Spanish licensed clinical psychologists ( N  = 350). 7 confirmatory factor analysis were performed to found a 20-item and 5-factor solution that had the best fit indices and internal consistency values. The original abbreviated model of the PST-Q was partially confirmed, since item 28 had to be eliminated because it had a factor weight less than .30. The alpha values were slightly lower than the original, but equivalent to those of the Portuguese validation. The implications of the findings for training and research in psychotherapy and clinical psychology are discussed. Keywords : Personal style of the therapist; PST-Q; practice-oriented research; clinical psychology; psychotherapy.

El objetivo del estudio consistio en proporcionar evidencia preliminar sobre sus propiedades psicometricas y estructura factorial en una muestra de psicologos clinicos espanoles debidamente acreditados ( N  = 350). Se realizaron 7 analisis factoriales confirmatorios hasta dar con una solucion de 5 factores y 20 items que resulto ser la que presento los mejores indices de ajuste y de consistencia interna. Se confirmo parcialmente el modelo abreviado original del EPT-C, ya que tuvo que eliminarse el item 28 por presentar una carga factorial inferior a .30. Los valores alfa fueron ligeramente inferiores al original, pero equivalentes a los de la validacion portuguesa. Se discuten las implicaciones de los hallazgos para la formacion e investigacion en psicoterapia y psicologia clinica.  Palabras clave : Estilo personal del terapeuta; EPT-C; investigacion orientada por la practica; psicologia clinica; psicoterapia.
