Although communication skills may be learned in a clinical setting by trial and error, a more formal approach to instruction is more efficient and enhances student confidence.9 Communication in health care is not a personality trait but rather a series of learned skills9 that can be taught, learned, and retained.10 Studies have shown enhancement of communication skills, patient satisfaction, time management, and patient assessment as a result of communication skills training.10,11
The Accreditation Standards for Dental Education Programs include competencies in interpersonal and communications skills.12 Yet, in 2002, Yoshida et al.13 reported that, of forty U.S. and Canadian dental schools, only fourteen had courses specifically focusing on communication skills. Lectures were the most common teaching method, and written examinations were more frequently used for assessments. Three schools had interdisciplinary courses with schools of medicine, and eight schools did not formally teach communication skills. Hence, dental schools may be falling short of accreditation guidelines and the needs of the students and patients they serve.
Lack of curricular time, faculty time, and funding are potential limitations for communication skills training in dentistry. In particular, observation and feedback on students communication skills are time-intensive. Simulated patient exercises and peer teaching have the potential to be both effective and efficient strategies. Simulated patients are a feasible and effective method of teaching and assessing communication skills in the health care setting.14–18 Peer teaching has potential advantages beyond its use in addressing the dental school faculty shortage. Bibb and Lefever reported that peer teaching programs may encourage dental students to consider careers in academic dentistry and foster greater enthusiasm for subject matter gained by both student instructors and their learners.19 Other benefits of peer teaching programs, such as greater teamwork, confidence, and respect for peers, are vital in developing professionalism.20–24
Faculty members at Virginia Commonwealth University School of Dentistry (VCU SOD) noted that the curriculum had limited opportunities for formal instruction on communication skills, assessment of skills, or performance feedback. Based on anecdotal evidence, students had difficulty organizing the dental interview, obtaining accurate information from patients, and determining patients perspectives on their oral health care. VCU SOD lacked key resources for program development; there was limited faculty expertise in teaching communication skills, limited faculty time, and minimal funding. To address these issues, VCU SOD faculty consulted with VCU School of Medicine (SOM) faculty who had experience designing and implementing a communication skills program. Based on the clinical education literature and the resources available at VCU SOD, a communications skills program was developed.
This article describes the development and implementation of an instructional program for dental communication skills and student perceptions of the program.
| Program Development |
|---|
|
|

Based on Millers framework, the VCU SOD communication skills program was structured with four components: 1) Knowledge, 2) Observation, 3) Simulation, and 4) Experience (KOSE). In KOSE, students acquire knowledge about effective clinician-patient communication, observe faculty demonstration of skills, practice in a simulated environment, and then hone their communication skills through real patient experiences. The Knowledge, Observation, and Simulation components occur in the second year of dental school, and Experience occurs during third-year clinical work.
The goal of the KOSE program is the development of effective clinician-patient communication skills. The program teaches these skills in the context of caring for patients with periodontal disease, for whom patient motivation and commitment to treatment are critical. Patients must be educated about the chronic nature of the disease, the causative and contributing factors, the treatment options, and the importance of self-care. The KOSE program was designed to teach communication in the context of a narrow content area so that students could focus on developing their communication skills. The program was designed so that communication skills gained from managing periodontal patients could be applied in other clinical situations. The first three components of the KOSE program were developed as modifications to existing second-year dental school courses of Periodontics (Knowledge and Observation) and Clinical Skills (Simulation). The fourth component of the KOSE program (Experience) is direct patient interaction in dental school-based and community clinics throughout the third year of dental school. The program was initiated in 2004–05 for the graduating class of 2007. Refinements were made based on that experience for 2005–06 (class of 2008). The program was implemented again in 2006–07 (class of 2009), when program evaluation was initiated.

|

Observation.
This one-hour interactive teaching session for D2s includes both observation and practice. First, a scripted role-play by two dental faculty members demonstrates less effective clinical communication skills. See Table 1
for examples of dialogue. During the role-play, students use checklists to identify the communication skills that they observe. Students discuss their observations and offer suggestions for improvement. A second scripted role-play demonstrates more effective communication skills.
|
Simulation.
A one-hour simulated clinic session engages small groups of D2s in role-playing exercises with paired fourth-year medical student (M4) and fourth-year dental student (D4) co-instructors. The simulation takes place in the dental school clinic. Three D2s each have an opportunity to role-play the clinician with a simulated patient portrayed by the M4. For each role-play, the other two D2s and the D4 observe the clinician-patient interaction, using checklists to assess the communication skills. Following the role-play, the student-clinician completes a self-assessment. Feedback after the role-plays is given by all members of the group in an interactive format facilitated by the M4 and D4. Checklists that were completed during each role-play help participants focus on specific skills. The discussion includes strengths and weaknesses for both the process of communication and the oral health content that was conveyed by the "clinician." Each role-play is fifteen minutes, and feedback is given in the last fifteen minutes of the session.
The role-plays depict three simulated patients, each with periodontal disease: 1) the anxious patient, 2) the inquisitive patient, and 3) the indifferent patient. For each case, the patient persona, patient demographics, chief complaint, medical, dental, and social histories, findings from clinical examination, periodontal diagnosis, etiology, and treatment options are outlined for the D2 and for the M4 and D4 co-instructors. In preparation for this simulated clinic, D2s have a twenty-minute orientation one to two weeks prior to the session. D2s are oriented to student roles and responsibilities. Patient cases are distributed at that time so that D2s can prepare for their individual role-play.
M4 and D4 students are carefully selected and trained as co-instructors for the simulated clinic experience. Both D4s and M4s are recruited from groups of students who have experience as teaching assistants. The D4s are experienced in teaching physical diagnosis and preclinical operative dentistry to D2s. The M4s are experienced in teaching clinical interviewing and physical diagnosis to first- and second-year medical students. Additionally, the M4s completed a fifty-five hour medical teaching elective. Since all D4 and M4 students involved in these teaching activities had been selected for their potential as teachers, a general call for peer communication instructors is put forth in these groups. Students are offered a modest financial incentive for their instruction and time spent in pre-session training.
Twelve M4 and D4 recruits attend a two-hour mandatory training session. Medical students are paired with dental students. Collegiality amongst the medical-dental student pairs is fostered by incorporating interactive activities into the training session. The following topics are covered: 1) description of simulated session, including student roles and responsibilities; 2) guidelines for portraying the patient cases; and 3) facilitating feedback sessions. Guidelines for portraying the patient include the importance of staying in character. For each role-play, M4s are instructed to ask one question about diagnosis, etiology, and treatment options, to object to a treatment recommendation, and to offer one nonverbal clue of misunderstanding. D4s are directed to take attendance, give initial instructions to group members, distribute and collect checklists, and keep time. The co-instructors are taught to facilitate the feedback discussion, emphasizing communication strengths and identifying one or two weaknesses. The M4s are asked to focus on the verbal and non-verbal communication process, while D4s focus on the clinical oral health content. Co-instructors are asked to elicit ideas from the D2s on how to improve communication skills.
Experience.
As VCU D2s matriculate into the third year of dental school, they have extensive contact with patients. Third-year dental students (D3s) treat patients in the schools clinics at least four days per week and provide comprehensive care to patients within their patient pool. These students also rotate through on-site specialty, hospital-based, and off-site community general practice clinics for approximately four to six weeks during their third year. These experiences provide numerous opportunities for D3s to interact with diverse groups of patients in various health care facilities and apply their communication skills to direct patient interactions. Students are informally observed while interacting with patients in the dental school and community clinics including, but not limited to, patient interviewing, motivation, and obtaining informed consent. D3s may obtain feedback on their communication skills both verbally and in writing.
Resources Required.
The KOSE communication skills program was designed to offer instruction, individual practice, and feedback to each student within the constraints of limited resources. The communication skills lecture required one dental faculty member, and the observation session required two. The simulated clinic session required six M4s and six D4s for peer instruction, one faculty member for oversight, and two staff members (ten hours total) for logistical support. Consultation for program development and evaluation was provided by two faculty members from the SOM. Curriculum time (prior to actual clinical experience) was limited to three hours per student: one hour for lecture, one hour for observation, and one hour for simulation. However, the observation was conducted twice, each session involving half the class. The simulated clinic required eight sessions, done in two four-hour blocks, to accommodate all students. Outside of faculty time, the program cost approximately $1,500 to provide lunches and stipends to M4 and D4 peer teachers.
| Program Evaluation Methods |

The KOSE program evaluation addressed student perspectives on three questions:
Surveys were developed to assess these questions utilizing VCU SOD curriculum objectives and the Accreditation Standards for Dental Education Programs.12 For the majority of survey items, students were asked to rate their level of agreement using a five-point Likert scale that ranged from 1=strongly disagree to 5=strongly agree. Open-ended items invited narrative comments. Demographic information was included. Surveys were reviewed and revised by dental and medical school faculty with experience in teaching communication skills. The underlying assumption was that students would report that the communication skills exercises enhanced their learning and that the program would have a positive impact on the way they approached patients in the clinical environment.
Observation.
Upon completion of the faculty role-playing exercise, a survey with six Likert scale items was administered to the D2s (Table 2
). The survey analyzed their perceptions of the efficacy of faculty role-playing in preparing them to communicate with patients.

Experience.
D3 perceptions about changes in their communication skills were gathered through post-training surveys using the retrospective pre- to post-test methodology.32,33 The retrospective pretest methodology was used in order to avoid a response-shift bias, which occurs when the educational intervention itself changes the learners understanding of competence. Responses to a conventional pretest would be calibrated to a naïve standard of competence, and post-test responses would be based on a more informed (recalibrated) standard. Thus, use of the retrospective pre- to post-test methodology addresses the response shift bias.
After one year of real patient experience, D3s completed a survey with thirteen Likert scale items asking them to rate their communication skills before and after participation in the KOSE program. A variety of skills were assessed including the ability to recognize verbal and nonverbal cues, increase accuracy of history taking, motivate patients, and provide appropriate information (Table 4
). Data were analyzed using a paired sample t-test and Cohens d measure of effect size.

Ninety-three percent of D2s indicated that observation of the faculty role-playing exercise was worthwhile (Table 2
). While only 51 percent indicated that they felt more comfortable with role-playing, 97 percent agreed that they were better prepared to distinguish effective from non-effective communication and 94 percent reported learning skills that will help them in the future. In narrative comments, D2s commonly reported learning the importance of listening to patients concerns (73 percent), reducing medical and dental jargon (68 percent), and being conscious of nonverbal cues (54 percent).
Most D2s (91 percent) felt the simulated clinic exercise was worthwhile (Table 3
). Students were comfortable practicing communication skills in front of their group members (78 percent) and were willing to participate again (81 percent). When asked what they learned from the exercise, D2s frequently responded with 1) importance of verifying patients understanding of planned treatment by asking open-ended questions (80 percent); 2) use of appropriate language (78 percent); 3) avoidance of medical/dental jargon (72 percent); 4) maintenance of eye contact (66 percent); 5) importance of developing rapport with patients (60 percent); 6) paying attention to patients nonverbal cues (57 percent); 7) importance of demonstrating empathy (54 percent); 8) structuring an interview/meeting with a patient (40 percent); and 9) diagrams/pictures enhance explanation of disease state (32 percent). D2s expressed a need for more time in each activity (20 percent), a shorter rating checklist (8 percent), and more time to practice these skills after the session (6 percent). In addition, D2s agreed that the dental (93 percent) and medical student (91 percent) instructors helped them develop their communication skills.
All M4s and D4s provided positive feedback on the simulated clinic sessions. Both groups agreed (M4s [94 percent] and D4s [90 percent]) that the training session adequately prepared them for the simulated exercises. A high percentage of M4s and D4s also agreed with the following survey items: 1) I was comfortable assessing D2s (89 percent); 2) I would encourage other M4/D4 students to participate in this activity next year (88 percent); and 3) D2s were prepared for and engaged in the exercise (82 percent). Ninety-two percent of M4s agreed that they were comfortable playing a simulated patient. M4s and D4s reported that more time should be allotted for each session (22 percent) and that the checklist was too complicated (6 percent). They also felt that the addition of charts or radiographs to the cases might enhance the activity (24 percent).
After completing the entire KOSE program, including one year of direct work with patients, D3s reported improvements in specific communication skills (X=3.75 to 4.09) (Table 4
). These shifts from pre- to post-values were seen in all areas with t-values that ranged from –3.18 to –5.53 (p<.001). In addition, the Cohens d values indicated moderate to high practical significance (d=.56 to .96). Of the skills that reached moderate to high practical significance, up to 48 percent of students rated an improvement in skills by one using the five-point Likert scale, and up to 11 percent of students rated an improvement by two or more.

This VCU SOD communications skills program is notable for its success despite limited faculty time, limited curriculum time, and limited financial resources. Collaboration with faculty in the SOM aided program development. Senior medical and dental students provided the patient simulation, communication skills assessment, and feedback necessary for the small-group simulated clinic experience.
Program evaluation focused on students recognition of effective clinician-patient communication, awareness of their own strengths and weaknesses as communicators, and application of learned skills to real patient interactions. D2s reported that the Observation and Simulation components of the program were beneficial, enhanced their ability to distinguish between more and less effective communication, and made them aware of their strengths and weaknesses as communicators in the health care setting. D3s perceived that their skills enhanced from before to after participation in the program. Students reported that they learned how to listen to patients concerns, build rapport with patients, reduce medical and dental jargon, negotiate a mutually acceptable treatment plan, and recognize patients nonverbal cues. Overall, students perceived the communication skills development program to be worthwhile and a useful part of their educational experience.
Most of the peer instructors found the experience valuable enough to recommend it to others. Fourth-year dental students commented that they learned communication skills that they would use in future practice. Medical students reported that they learned something new about dentistry and about oral health. These findings are consistent with research demonstrating that peer teaching positively affects the learner and instructor by reinforcing concepts and enhancing motivation for learning.19 Peer teaching has the potential to help address the dental school faculty shortage34 and foster interest in dental education. This program is notable for utilizing peer instruction across disciplines, with potential benefits of building respect and collegiality between professions and enhancing student understanding of the scope of practice and the importance of collaboration in the comprehensive management of patients.
Interdisciplinary course planning amongst health sciences faculty offers opportunities for resource sharing, collaborative relationships, and professional development. Building relationships with faculty members outside of dental schools may provide teaching materials and human resources needed to enhance the delivery of dental education. These relationships may also support professional development since they expose health sciences faculty members to new teaching methodologies and content knowledge. Furthermore, collaborative relationships amongst faculty may enhance job satisfaction and faculty retention.35,36 The importance of multidisciplinary collaboration has been supported on a national level as explained in the 2003 Report on Academic Health Centers, which strongly endorses the integrated development of educational curricula and approaches to teaching health professionals.37
There are several limitations in the evaluation of this educational innovation. The evaluation was based on student perspectives at one academic institution. Measures of actual student performance could provide better measures of the programs effects on knowledge and skills. Objective measurement could include pre- and post-knowledge testing of communication protocol, accuracy of gathered information during patient interviewing, and patient retention rates. In this study, student perspective was gathered in a cross-sectional rather than longitudinal manner. However, the student demographics and the instructional program were similar for the two groups of students. Evaluation of the D3s perceived change in communication skills used the retrospective pretest methodology in order to avoid a response-shift bias. Potential limitations of this methodology are systematic cognitive biases due to a tendency to believe that the present self is better than the past self or due to an attempt to justify the effort expended with the belief that change must have occurred.32,33 Although the KOSE programs practical significance is difficult to quantify, 78 percent of D3s perceived an improvement in at least one specific communication skill. Skills such as recognizing patient nonverbal clues, exploring patient perspective relative to treatment preferences, and negotiating a mutually acceptable treatment plan were skills perceived to be enhanced. These skills are worth noting since they correspond to the fundamental definition of effective communication that was an integral part of program development.
There are several potential limitations to this learning experience. The skills of the M4s as simulated patients are unknown. Professional simulated patients (usually laypersons) go through extensive training and may differ in their portrayal of patients and their feedback. Although these medical students were not familiar with the dental aspects of the patient cases, they have more medical training than typical simulated patients, which might affect their role-play and feedback. The completeness and consistency of feedback given to D2s were not evaluated in this study. The teaching and clinical experience of the peer instructors, their level of training prior to the simulated session, and the short amount of time devoted to feedback may have affected the feedback given. This program gave students only one simulated practice opportunity using a narrow spectrum of the dental content and psychological issues facing practicing dentists. Multiple opportunities for observed practice with feedback may be required for students to learn and retain communication skills needed to manage the full scope of dental practice and the varied psychological, ethical, and cultural issues.
The KOSE program, utilizing interdisciplinary peer teachers for a simulated clinic experience, has been a successful approach to communication skills training in a dental school with limited resources for this aspect of the curriculum. Further development of the KOSE communication skills program will include more curricular hours incorporating a greater variety of dental scenarios. Additional outcomes data will include faculty ratings of M4s and D4s as simulated patients and peer instructors. This will help determine the authenticity of mock patients and the quality of performance-based feedback provided to D2s by their peer instructors. Modifications to the KOSE program will continue based on these findings and on further evaluation of students perceptions and performance.
