Effects of communication skills training on students' diagnostic efficiency.

This study evaluates the impact of a training programme in communications skills on subsequent diagnostic efficiency. Videotaped history-taking interviews conducted by groups of specially trained and control groups of students were rated for their diagnostic efficiency by two medical practitioners. Students in the trained group had shown greatly increased skills in interviewing and interpersonal effectiveness as a result of their training. A comparison of ratings given by the two experimentally naive, independent observers revealed that trained students were significantly better at eliciting full, relevant data from patients--they were diagnostically more efficient, but took no longer than their control group counterparts to elicit the information. Further research with the medical interview rating scale will clarify the skills required of medical students in interviewing and diagnosis and facilitate remedial training for students who show poor interview skills.
