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'. CONCLUSION: 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.     

The stability of maternal ratings of medical student interviews

INTRODUCTION: Little information is available on the intrarater reliability of parent ratings of medical student interview skills. The aim of this study was to compare maternal ratings of a videotaped medical student interview, with ratings by the same mother of the same interview seen a month later. METHOD: Thirty mothers rated 1 of 2 'medical student' interview videotapes (random allocation). An actor played the role of the student and demonstrated different student skill levels in each interview. Mothers rated the same interview again a month later (mean +/- SD 34 +/- 13 days). Maternal satisfaction was measured using the Medical Interview Satisfaction Scale (MISS, maximum score 203) and the Interpersonal Skills Rating Scale (IPS, maximum score 91) with higher scores indicating higher satisfaction. RESULTS: No significant differences in mean maternal ratings were observed following the first and second viewings of each interview. The average percentage difference in first and second viewing scores was MISS 4%, IPS 8% with correlation coefficients MISS 0.96, IPS 0.87 (P < 0.05). CONCLUSIONS: The high levels of stability in maternal evaluations of simulated medical student interviews supports the use of maternal evaluations for longitudinal monitoring of medical student performance.     

The association between maternal ratings of child health interviews and maternal and child characteristics

BACKGROUND: Doctors develop the skills needed to interview parents and children in paediatric settings by practice and by receiving feedback during their medical training. Interviewed parents are ideally placed to provide evaluations of these skills. If parents, as consumers of health care services, are to be consulted, it is important to determine whether factors other than interview skills affect their evaluations. OBJECTIVES: Our aim was to examine the relationship between maternal satisfaction ratings of student doctor interviews, and maternal and child characteristics. METHODS: Sixty mothers of children attending the paediatric medical out-patient clinic at the Women's and Children's Hospital, South Australia were allocated randomly to rate one of four video-taped final year student doctor interviews (15 mothers per interview). The level of skills displayed by the student doctor differed in each interview. Maternal satisfaction was measured using the Medical Interview Satisfaction Scale (MISS) and the Interpersonal Skills Rating Scale (IPS), and interview ratings were compared for a number of maternal and child characteristics. RESULTS: No significant associations were observed between maternal satisfaction ratings and any maternal or child characteristics other than lower satisfaction associated with previous experience of a real student doctor interview (P <0.01). The interview seen by mothers predicted 53% (MISS) and 65% (IPS) of the variance in maternal satisfaction ratings. After controlling for the interview type, the maternal and child characteristics studied predicted 17% additional variance in MISS scores and 7% in IPS scores. CONCLUSION: The quality of the interview skills demonstrated was the principle determinant of maternal satisfaction ratings.     

Do students develop better motivational interviewing skills through role‐play with standardised patients or with student colleagues?

OBJECTIVE: Smoking is the leading cause of preventable death in the USA and reducing the number of smokers by 50% is among the goals of the Healthy People 2010 initiative. Despite its importance, few medical students receive formal training in smoking cessation counselling. Motivational interviewing is a patient-centred, but directive, method of counselling that has been found to be more effective than giving brief advice for motivating smokers to quit. We wanted to determine whether using standardised patients to teach this skill to Year 3 medical students would be more effective than using student role-plays. METHODS: We conducted a randomised, controlled trial of 93 Year 3 family medicine clerkship students at our medical school between July 2003 and July 2004. The control group (n=46) practised motivational interviewing with one another and the intervention group (n=47) practised with standardised patients trained in motivational interviewing for smoking cessation. At the end of the study all the students conducted an interview with a different standardised patient that was videotaped. The primary outcome was analysis by a trained masked evaluator of the quality of a final videotaped interview using the motivational interviewing treatment integrity code (MITI), which assesses the quality of the interview according to 6 different criteria. RESULTS: There was no significant difference between the control and intervention groups in the final analyses of the interviews. CONCLUSIONS: According to MITI scores, standardised patient role-plays are similar in effectiveness to student role-plays when teaching basic motivational interviewing skills for smoking cessation to Year 3 medical students.     

Consulting skills training and medical students' interviewing efficiency

In more traditional medical education, medical students took a patient's medical history by asking a series of sequenced, routine questions, covering presenting medical problem(s); medical history; social and personal history; systems review; and physical examination. Following this process, the student then attempted to derive the patient's medical problems. This inductive problem-solving paradigm may not assist students to prepare for their future interviewing needs, given doctors use a hypothetico-deductive, problem-solving approach when interviewing patients and numerous researchers have developed specialized communication skills training programmes designed to enhance students' interviewing skills. Students given specific consulting skills training have tended to show significantly greater interpersonal effectiveness and improved interview behaviours compared with students who experience traditional patient clerking training. These improvements in interviewing tend to persist over the period of students' medical training. The aim of the present study was to determine whether specialized communication skills training helped students elicit greater quantity and quality of information from patients and if so, whether such information assisted students in improving their diagnostic skills. Videotaped history-taking interviews conducted by students trained in communication skills and untrained (control) students were rated for their interview efficiency. A comparison of ratings given by experimentally naive, independent observers revealed that trained students were more efficient, but took no longer than their control group counterparts to elicit fuller, more relevant information. However, the student groups did not differ in the accuracy or scope of their medical diagnoses. It is argued that students' lack of medical knowledge in this early phase of their clinical training militated against their being able to use their interviewing competence to derive more potentially accurate medical diagnoses.     

The importance of race in medical student performance of an AIDS risk assessment interview with simulated patients

INTRODUCTION: This study was done to ascertain the effect of race on medical student-patient communication. The primary hypothesis was that interviewing performance scores would be higher when race of student and race of simulated patient instructor (SPI) were concordant than when they were discordant. METHODS: Data obtained from student interactions with four Caucasian and four African American female SPIs participating in a case involving an AIDS risk assessment interview were analysed. Performance was assessed using two instruments: an 8-item behaviourally anchored interviewing skills scale and a 14-item checklist reflecting content relevant to sexual behaviour and AIDS risk. SPI groups were comparable and SPIs were trained to a high level of inter-rater reliability. Students (24 African American and 180 non-African American) were assigned to SPIs based on the spelling of the student's name. Performance was scored independently at the conclusion of each interview by both the SPI and the student her/himself. RESULTS: African American students had lower scale scores than non-African American students in interactions with Caucasian (but not African American) SPIs; and all student scores, both on the skills scale and the content checklist, were higher with African American than with Caucasian SPIs (as assessed by both SPI and student). Women students had higher scores than men. CONCLUSIONS: Race of SPI has an influence on student performance of an AIDS risk assessment interview. Further studies focusing on racial interactions in the medical interview are required. It appears that race of SPI may need to be accounted for in the development and interpretation of SPI-based clinical competence exams.     

Behavioural assessment of the effectiveness of a communication programme for medical students

Summary. This study evaluated the effectiveness of a communication programme taught to medical students at the University of Melbourne in their preclinical years. The effectiveness of the programme was assessed by comparing videotaped history-taking interviews completed by a cohort of first-year clinical students in 1986, who had not undertaken the communication programme, with a similar cohort of first-year clinical students in 1992 who had undertaken the programme. The students from the 1986 cohort who had not undertaken communication training in their preclinical course completed their videotaped interviews as part of the experimental evaluation of a consulting skills training programme carried out in 1986-87. A comparison of ratings given by two experimentally naive, independent observers revealed that the 1992 student cohort demonstrated some significantly better skills at questioning and facilitating communication with patients. By contrast, the 1986 student cohort showed significantly greater skills at maintaining relevance in their interviews and greater capacity to explore patients' psychosocial concerns. These data suggest that students acquire the most effective interview skills when interacting with patients during their clinical training.     

Patient-centred consultations: a comparison of student experience and understanding in two clinical environments

OBJECTIVES: To explore students' perspectives on doctor-patient communication. DESIGN: We interviewed students in focus groups before and after their placements. In semistructured interviews they were asked about their experiences of learning through clinical contact, with particular emphasis on patient-centred consultations, on the wards and during their community attachment. Students whose clinical skills training remained hospital-based were also interviewed to compare the range of experiences. SETTING: Leeds University. SUBJECTS: Third-year medical students. RESULTS: During hospital training students are rarely introduced, either through teaching or observation, to the idea of patient-centred consultations. In contrast both the principles underpinning and/or the practice of such consultations were routinely encountered during the general practice placement. Students considered the community attachment to have helped them appreciate the value of exploring patients' concerns both in terms of enhancing the patients' overall healthcare experience and promoting effective clinical management. While they considered the nature and purpose of hospital care to be qualitatively different from that conducted in the community, the relevance of adopting a patient-centred approach on the wards was confirmed. CONCLUSIONS: Recommendations for clinical training are made. The relevance and best use of community and hospital-based attachments need to be evaluated further.     

Teaching interviewing skills to paediatric junior clerks using simulated mothers

In this article a training programme is described for improving interviewing skills of students in the fifth year (junior clerkship) of the medical curriculum. Two interviews with a 'simulated mother' form the core of the programme. The interviews are immediately followed by a feedback session in which the simulated mother discusses the strong and the weak points of the interview. In the feedback she makes use of a checklist with relevant points concerning the content and the process of the interview. Where required the comments are substantiated with fragments of the videotaped interview. In a 2-hour theoretical session, students are told how to prepare themselves for the interview. The learning effects of the training programme using simulated mothers were evaluated in order to determine: (1) the subsequent improvement in interviewing skills; and (2) the effect of the feedback session. It was found that students' interviewing skills improved significantly on the content and the process aspects after one or two interviews. In addition the feedback sessions proved very helpful, although no significant differences were revealed, when comparing the mean group scores for students who had had feedback sessions with the scores for those who had not. The results also revealed that two interviews were insufficient and that the training should include at least three interviews. This was borne out by the large number of students who asked for more interviews with simulated mothers. In the training programme the simulated mothers perform two functions: (1) playing the role of the mother of a sick child; and (2) giving feedback to students regarding their interviewing skills.(ABSTRACT TRUNCATED AT 250 WORDS)     

Educational assessment of general practice experience for psychiatric trainees

Eighteen psychiatric trainees spent 6 months each as general practice trainees. The educational impact of the experience was assessed by a self-assessment questionnaire, a semi-structured interview and a videotaped interview with a psychiatric patient. Each assessment was conducted at baseline and after 12 months. A control group of 14 trainees was recruited from the same rotation. On the self-assessment questionnaire, the study registrars rated their abilities to solve general medical problems significantly improved compared to controls. They had also acquired greater understanding of the limitations of their knowledge and their legal responsibilities towards their patients. The semi-structured interview failed to distinguish between the two groups. Videotapes for rating at baseline and follow-up were available for only 17 of the trainees. Assessment of the tapes used the Maguire Scale and the Interview Behaviour Scale. Neither scale demonstrated any intervention effect. The interviews were all characterized by a preponderance of 'closed psychological' and 'checking-out' questions. It appears that psychiatric trainees' interviewing styles had not been influenced by the experience. This study suggests that psychiatric trainees gain greater confidence in their role as a doctor and greater understanding of the scope and nature of general practice by such an attachment. It is unclear whether or not supplementary interviewing skills had been acquired which were not utilized in the taped interview, which conforms very much to traditional psychiatric examination behaviour. Trainees were reassured that they had increased their knowledge without losing any of their specific professional skills.     

Developing a new line of patter: can doctors change their consultations for sore throat?

BACKGROUND AND OBJECTIVES: Doctors report pressure from peers to reduce prescribing of antibiotics for minor respiratory illnesses, and from patients to do the opposite. It has been suggested that doctors adopt a more patient-centred consulting style in order to encourage patient satisfaction and shared decision-making. No evidence exists that such changes are achievable. We developed a new, on-site method for training postgraduates and used this for teaching patient-centred intervention. Here, we examine whether this training method is associated with changes in consulting patterns in consultations for sore throat with children, among doctors from a single group practice. METHODS: Audiotaped consultations (simulated and real) conducted before and after training were analysed and interviews were carried out with participants about the impact of training. SETTING: A general practice in South Wales. PARTICIPANTS: Four general practitioners who consulted with 25 real and simulated patients participated in the study. MAIN OUTCOME MEASURES: Four patient-centred skills used by doctors and 2 patient behaviours measured before and after training were identified. RESULTS: Three out of 4 practitioners produced clear evidence of changes in patient-centred consulting skills. These changes were evident in simulated and real consultations 2 and 4 weeks later, respectively. Prior to training the doctors produced only five examples of patient-centred skills in 10 consultations. After training they produced 39 examples in 15 consultations. CONCLUSIONS: Evidence from both consultations and interviews indicated that the intervention and training were well received and had been put into practice.     

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.     

Medical students as standardized patients to assess interviewing skills for pain evaluation

PURPOSE: The use of medical students as standardized patients in a performance assessment of pain evaluation was studied. METHODS: Fifty-two pairs of second-year medical students participated. One student portrayed a patient presenting with cancer pain and was interviewed by the other medical student. The student-patient then rated the interview using a checklist of pain assessment and general interviewing skills. The interviews were audiotaped and also rated independently. RESULTS: Based on student-patient ratings, 36 (69%) students demonstrated 9 or more of the 11 pain-specific checklist items, compared to 34 (65%) students according to the trained rater. Highly specific pain-related items had higher agreement than broader interviewing skill items. There would be differences in the summary assessments of students depending on which rating data were used. DISCUSSION: Medical students represent a readily accessible resource as patients for clinical simulations. Students tended to overestimate the performance of fellow students, but acting as a standardized patient had educational value, and can be used to extend simulated patient encounters within the curriculum. Further investigation is needed to improve the reliability of the feedback provided by student-patients.     

Evaluating medical students' non-verbal communication during the objective structured clinical examination

OBJECTIVES: Non-verbal communication (NVC) in medical encounters is an important method of exchanging information on emotional status and contextualising the meaning of verbal communication. This study aimed to assess the impact of medical students' NVC on interview evaluations by standardised patients (SPs). METHODS: A total of 89 medical interviews in an objective structured clinical examination (OSCE) for post-clerkship medical students were analysed. All interviews were videotaped and evaluated on 10 non-verbal behaviour items. In addition, the quality of the interview content was rated by medical faculty on 5 items and the interview was rated by SPs on 5 items. The relationships between student NVC and SP evaluation were examined by multivariate regression analyses controlling for the quality of the interview content. RESULTS: Standardised patients were likely to give higher ratings when students faced them directly, used facilitative nodding when listening to their talk, looked at them equally when talking and listening, and spoke at a similar speed and voice volume to them. These effects of NVC remained significant after controlling for the quality of the interview content. CONCLUSIONS: This study provided evidence of specific non-verbal behaviours of doctors that may have additional impacts on the patient's perception of his or her visit, independently of the interview content. Education in basic NVC should be incorporated into medical education alongside verbal communication.     

Martin's Map: a conceptual framework for teaching and learning the medical interview using a patient-centred approach

OBJECTIVE: At the end of training, students seem to lack a basic understanding of how to take an organised, relevant medical and social history using a patient-centred approach. The aim of developing the map described in this paper was to provide a framework for such an approach. METHODS: Action research was used to continuously modify and refine an interview map that was used by medical clerks, family medicine residents, international medical graduates and practising doctors for teaching and learning purposes over a 10-year period. CONCLUSION: 'Martin's Map' provides a realistic framework for flexibly organising and integrating medical content with process that did not previously exist. The map provides medical educators with a standardised framework for talking about the medical interview, which helps learners understand how to use their medical knowledge with a patient-centred approach. Learners are able to visually see how they can take a focused medical and social history using a patient-centred approach, which subsequently seems to help them organise their thinking and approach during the medical encounter.     

Simulating the longitudinal doctor-patient relationship: experiences of simulated patients in successive consultations

CONTEXT: The use of simulated patients (SPs) in teaching communication and practical skills at medical schools is mostly limited to single-case use: a student has 1 consultation with an SP and receives feedback afterwards. Very little literature is available that describes consecutive consultations between the same student and SP. In this study, we explored the experiences of SPs in a new, longitudinal SP programme in which SPs met the same Year 3 students ('GP') in 4 consecutive consultations during the year. The SPs suffered from a chronic disease in their patient roles. METHODS: Four focus group discussions were conducted with 23 SPs (8 men, 15 women; average age 60.9 years) who had performed in the new programme. Discussions were semi-structured and followed a pre-established interview guide. Data were categorised by 3 independent raters. RESULTS: The SPs described the development of a more familiar relationship with students under the new programme, compared with single-case consultations. They developed specific expectations of students' performances. The SPs enjoyed participating in the programme and felt it was more realistic than single-case consultations. Feedback changed and became more detailed as SPs were able to compare consultations; students' response to feedback could be experienced during the next consultation. DISCUSSION: Practising the development of a realistic, longitudinal doctor-patient relationship may help prepare students for real practice. Longitudinal feedback is now possible; it may be of higher quality and of benefit to SPs as well. These findings suggest new possibilities for SP-based education and research. Future studies should focus on quantitative analysis and students' perspectives.     

Videotaped interviewing of non-English speakers: training for medical students with volunteer clients

In a multicultural society such as Australia, with over 20% of its population born overseas, interpreters are often required to facilitate medical interviews. However, where a patient has some proficiency in English, medical interviews are sometimes conducted across the boundaries of culture and language. This is a report of an educational innovation to teach interviewing skills to pre-clinical medical students with the assistance of volunteers of non-English-speaking backgrounds. Pre-clinical students interviewed community volunteers on topics of general life history in a sequence of 16 tutorials. Each student conducted two interviews. Teaching methods included feedback from the volunteers, tutorial discussion facilitated by playback of videotapes, and modelling of skills by the teachers. Evaluations by volunteers and students indicated high satisfaction with the teaching methods and outcomes. Students gained confidence in interviewing people from different cultures. Evaluation of students' pairs of videotapes by an independent rater achieved satisfactory reliabilities and indicated significant gains in inquiry skills and the communication of positive attitudes. Skills in communicating empathy and in using simple language did not improve measurably.     

Retention of interviewing skills learned by first-year medical students: a longitudinal study

A pilot interviewing course was offered as an elective to first-year medical students in the spring of 1985. A quasi-experimental pre-test/post-test control group demonstrated that students who took the course exhibited a significant increase in interviewing skills. Subjects, 15 in the experimental group and 11 in the control group, were assessed in each of the following 3 years. Data consisted of five 10-minute videotaped interviews with real or stimulated patients for each subject and subject's responses on a degree of confidence, familiarity and anxiety scale. Interviews were rated on 43 behaviours by two independent coders with a 90% simple agreement. The experimental group did not maintain their scores on interviewing skills and both groups showed a significant decline in nine skills comprising empathy. The only significant difference between the groups in fourth year was on the degree of confidence experienced. While interviewing skills can be learned they decline in the clinical years as students learn medical problem-solving. If medical students are to graduate with their original empathy intact, a follow-up course in fourth year is indicated.     

Interviewing skills training--a study

A randomized investigation was conducted to study the effect of a structural 10-week course on the development of interviewing skills of first year medical students. The experimental group (16 students) received interviewing skills training based on the Developmental Helping Model as described by Carkhuff in 1982. The comparison group (16 students) received traditionally focused training with emphasis on gathering information about the patient's presenting problem through the use of open-ended questions. The dependent measure was interviewing skills level. Each student was videotaped with a simulated patient during the initial (pre-test) and final (post-test) sessions of the course. Tapes were rated by blinded reviewers according to Carkhuff's five point scale of Developmental Helping. No pre-test differences were found between groups. At post-test, the experimental group showed significantly higher ratings. This data suggests that teaching specific interviewing skills is more effective than non-skill oriented training for development of medical students' ability to interview patients.
