[A pilot study of the reliability and validity of the Turkish Cognitive Therapy Adherence And Competence Scale].
OBJECTIVE
The aim of this study was to investigate the reliability and validity of the Turkish Cognitive Therapy Adherence and Competence Scale (CTACS) (Liese, Barber, and Beck, 1995). The scale is based on the evaluation of video taped therapy sessions using a certain coding system.


METHODS
In the content validity study, 4 judges placed items within the intended theoretical construct with a high degree of consensus. In the following part of the study, 2 judges coded 20 video taped therapy sessions randomly selected from a pool recorded at the Hacettepe University Psychotherapy Research Laboratory.


RESULTS
The internal validity of the scale was alpha=0.84 for adherence and alpha=0.83 for competence. The intra-class correlation (ICC) coefficients were calculated using the absolute consensus method to determine inter-judge reliability coefficients for the data obtained from 2 judges. Mean ICC was 0.70 for the adherence dimension and 0.60 for the competence dimension. The relationship between adherence and competence was examined using Pearson's correlation coefficients, which were r=0.95 (n=20, P<0.001) for the first judge, r=0.97 (n=20, P<0.001) for the second judge, and r=0.95 for both judges.


CONCLUSIONS
As preliminary evidence our findings suggest that the Turkish CTACS has acceptable levels of content validity and inter-judge reliability for use in clinical and research settings.
