This study sought to describe counsellor -counselee interaction during initial cancer genetic counselling consultations and to examine whether the communication reflects counselees' previsit needs. A total of 130 consecutive counselees, referred mainly for breast or colon cancer, completed a questionnaire before their first appointment at a genetic clinic. Their visit was videotaped. Counselee and counsellor verbal communications were analysed and initiative to discuss 11 genetics-specific conversational topics was assessed. The content of the visit appeared relatively standard. Overall, counselees had a stronger psychosocial focus than counsellors. Counsellors directed the communication more and initiated the discussion of most of the topics assessed. Counselees did not appear to communicate readily in a manner that reflected their previsit needs. Counsellors provided more psychosocial information to counselees in higher need for emotional support, yet did not enquire more about counselees' specific concerns. New counselees may be helped by receiving more information on the counselling procedure prior to their visit, and may be advised to prepare the visit more thoroughly so as to help them verbalise more their queries during the visit. British Journal of Cancer (2005) The exchange of information is the core of cancer genetic counselling. Preferably, it supports a 'caring, professional relationship that offers guidance, but allows individuals and families to come to their own decisions' as put forward by the Proposed international guidelines on ethical issues in medical genetics and genetic services (1998). Several authors argued that counsellors should try to elicit counselees' needs and preferences at the outset, and to adapt their counselling accordingly (Michie et al, 1998;Bernhardt et al, 2000;Lobb et al, 2001). Findings on communication within general practice (Marvel et al, 1999;Street, 1991) and oncology (Ford et al, 1996) suggest that physicians rarely solicit patients' concerns and questions. At the same time, studies revealed that patients' strong desire for medical information did not prompt them to engage frequently in information-seeking behaviours (Beisecker and Beisecker, 1990). Butow and Lobb (2004) described the typical process and content of first genetic counselling consultations with women from high-risk breast cancer families. They found that counsellors provided detailed information on various aspects related to familial breast cancer but did not consistently elicit emotional concerns. Indeed, in another analysis of the data, Lobb et al (2002) found that counsellors did not adapt their counselling according to women's expectations or anxiety. Rather, women's professional occupation and disease status were predictive of the type of information that was provided and how this was delivered.The purpose of the present study was two-fold. First, it aimed to describe counsellor -counselee interaction during initial cancer genetic counselling consultations in terms of affective and taskoriented ...
