This paper describes the emergence of motivational interviewing in the
addictions field, and the development of broader negotiating methods
for use in medical consultations about behaviour change. It is argued
that much of this material should be relevant to the treatment of obes
ity in brief medical consultations. It should be possible to encourage
patients to be much more active in the consultation, and for practiti
oners to avoid some of the pitfalls of ineffective advice-giving. Four
potentially relevant clinical strategies are described.
