Questionnaires were used to assess radiotherapy patients (n = 111) characteristics before their first consultation, perception of information giving after the first consultation and trust before the follow-up consultation. Videotaped consultations were scored for the content of the information provided and information giving performance.
Patients mean trust score was 4.5 (sd = 0.77). The more anxious patients were, the less they tended to fully trust their radiation oncologist (p = 0.03). Patients¡¯ age, gender, educational attainment and anxious disposition together explained 7 % ; radiation oncologists¡¯ information giving (content and performance) explained 3 % , and patients¡¯ perception of radiation oncologists¡¯ information-giving explained an additional 4 % of the variance in trust scores.
It can be questioned whether trust is a sensitive patient reported outcome of quality of communication in highly vulnerable patients.
It is important to note that trust may not be a good patient reported outcome of quality of care. Concerning radiation oncologists¡¯ information giving performance, our data suggest that they can particularly improve their assessments of patients¡¯ understanding.
