VTT-TAB
Kurzskalen zur Erfassung von Vertrauen in der Psychotherapie
Short abstract
The VTT-TAB are designed to measure (1) confidence in the treating psychotherapist (SV-TAB, 14 items), (2) self-confidence in the psychotherapeutic setting (SVT-TAB, 12 items) and (3) confidence in the personal future through psychotherapy (ZUK-TAB, 10 items). They are based on the theoretical foundation of the model of trust triad (VTT) developed by Krampen (1997), which is based on the partial model of personality (HPP). Reliability: The one-dimensionality of the scales could be confirmed by means of the Rasch model. The internal consistency lies between Cronbach's Alpha = .88 and Alpha = .91. The selectivities of the items are above rit = .40 on all three scales. Validity: The scale intercorrelations are, in accordance with theory, at r = .58-.81. The construct validity is confirmed by the profile reliability with prof(rtt) = .63. The explorative principal component analysis suggests a two-factorial solution with 47.1 % variance elucidation. The VTT-TAB correlates with other relevant confidence scales. The external validity was checked and confirmed by calculations on the prognostic significance of the three confidence scales for the success of therapy using a sample of N = 203. Therapy-related confidence in the future represents the most variable predictor of symptom improvement.
