Adolescent psychotherapy process research: adaptation of the instrument APQ

Abstract The aim of this paper is to present the Brazilian version of the instrument APQ (Adolescent Psychotherapy Q-Set), including its translation and initial adaptation, followed by the construction of psychotherapy prototypes for psychoanalytic and cognitivebehavioral approaches. A total of 10 psychoanalytic and 10 cognitive-behavioral therapists were asked to classify the APQ items in relation to relevance to their theoretical model. Data were analyzed with factor analysis. The extraction of two factors explained 48.07% of the total variance. The Cronbach’s alpha for the psychoanalytic factor was 0.85 and for the cognitive-behavioral factor, 0.86. The former presented factor loadings ranging from .61 to .73, whilst the latter from .49 to 80. The prototypes were developed through linear regression calculations of each APQ item’s contribution to each of the factors. It was observed that the two prototypes adequately discriminated psychoanalytic and cognitive behavioral approaches, indicating that the APQ is an appropriate tool for research in psychotherapy. Resumen El objetivo de este artículo es presentar la versión brasileña del instrumento APQ (Adolescent Psychotherapy Q-Set), incluyendo su traducción y adaptación inicial, y la construcción de prototipos de psicoterapia en la adolescencia de orientación psicoanalítica y cognitivo-conductual. Se solicitó a diez psicoterapeutas psicoanalíticos y diez cognitivo-conductuales que clasificasen los ítems del APQ, teniendo en cuenta su relevancia para el modelo teórico. Los datos fueron sometidos a análisis factorial y la extracción de dos factores explicó 48,07% de la varianza total. El alfa de Cronbach del factor psicoanalítico fue 0,85, y del cognitivo-conductual 0,86. El primer factor presentó cargas factoriales entre 0,61 y 0,73 y el segundo entre 0,49 y 0,80. Cálculos de regresión lineal identificaron los resultados de contribución de cada ítem del APQ para cada factor, desarrollándose así los prototipos. Se observó que el enfoque psicoanalítico y cognitivo-conductual fueron discriminados, indicando que el instrumento es apropiado para el desarrollo de investigaciones en psicoterapia.
