Medical student interviewing: a randomized trial of patient-centredness and clinical competence.
BACKGROUND
It is widely accepted that the quality of doctor interviewing skills is an important determinant of health care outcomes. Two interviewing skills contributing significantly to optimal health outcomes are the clinical competence of the interviewer and the use of patient-centred techniques. However, the relative importance of these to health outcomes is unknown.


OBJECTIVE
The purpose of this study was to examine the relative effect on maternal recall and satisfaction of medical student clinical competence and use of patient-centred interview techniques.


METHODS
Sixty-nine mothers of children attending the Paediatric Medical Out-patient Clinic, Women's and Children's Hospital, South Australia agreed to participate in the study, with 60 successfully completing the study. They viewed two of four standardized 'medical student' interview videotapes in which the level of clinical competence and patient-centredness were varied independently. All other interview variables were controlled. Each mother rated the interviews by questionnaire (balanced incomplete block design, each interview rated by 30 mothers). Maternal satisfaction with the 'student' interview was measured using the Medical Interview Satisfaction Scale (MISS) and the Interpersonal Skills Rating Scale (IPS). Maternal recall of interview information was assessed by questionnaire, with maternal answers coded independently before analysis.


RESULTS
Significant, independent effects of clinical competence and patient-centredness were observed with both MISS (F = 42.1, P < 0.0001) and IPS (F = 49.3, P < 0.0001) scores. The effect of clinical competence was stronger than that of patient-centredness. Maternal recall for specific information was greater for some items following the more clinically competent interviews, but was lower for others. There was no association between maternal recall and the level of patient-centredness demonstrated by the 'student'.


CONCLUSIONS
Clinical competence was a more significant determinant of maternal evaluations of medical student interviews and maternal recall of information than was patient-centredness. High levels of both patient-centredness and clinical competence were associated with the highest maternal satisfaction.
