BITE supervision positively influences the therapeutic alliance and therapeutic competencies during cognitive-behavioural therapy. A supervision format that more directly addresses therapeutic processes is more effective in improving those processes than an indirect supervision format. Pre-treatment differences between therapists might explain the superiority of BITE supervision. BITE supervision can be considered a safe intervention.

Clinical implications Treatment failure is associated with a lower therapeutic alliance in cognitive-behavioural treatment. Therapeutic alliance seems to be an important precondition for the adherent and competent implementation of therapeutic techniques. Therapeutic alliance should be monitored during psychotherapeutic treatment. Cautions or limitations Results are limited to cognitive-behavioural therapy and may not be representative for other treatment approaches. Process analyses are based on highly standardized randomized controlled trials and may not be generalizable to routine care.

The results suggest high efficacy of CT as well as ET in the treatment of hypochondriasis. Cognitive interventions were not a necessary condition for the change of dysfunctional cognitions. These findings are relevant to the conceptualization and psychotherapeutic treatment of hypochondriasis and health anxiety.

Nondisclosure is considered to be a central obstacle to effective psychotherapy supervision. The aim of the current study was the validation of the German version of the Supervisory Questionnaire (SQ; Yourman & Farber, 1996), a short measure for the assessment of supervisee nondisclosure. The investigation was based on a sample of 589 supervisees. Confirmatory factor analyses suggested a two-factor model of the SQ which included one factor describing nondisclosure regarding the patient (α=.74) and another describing nondisclosure regarding the supervisor (α=.71). The SQ demonstrated satisfactory convergent and discriminant validity. Additionally assessed supervisee characteristics accounted for 16% of the variance in nondisclosure. These results provide general support for the reliability and validity of the SQ in a large sample of supervisees.
