Eighty five volunteer general practitioners in Lothian region recorded clinical and contextual information on 21,000 consultations during 1987-88. During their recording sessions they reported their perceived levels of stress using a previously valid
Eighty five general practitioners in the Lothian region recorded information on all surgery consultations on one day in every 15 for a year. On the basis of their mean consultation times with patients the working styles of the general practitioners w
