Introducing conflict resolution and negotiation training into a biomedical sciences graduate curriculum

Background Analysis of the biomedical workforce and graduate education have produced recommendations for modifications of pre-doctoral training to broadly prepare trainees for wider ranging scientific careers. Development of training in professional skills is widely recommended, but details of implementation are not widely available. In alignment with these recommendations, we have incorporated professional skills training into the biomedical science graduate curriculum at West Virginia University. An important component of the training is developing conflict resolution and negotiation skills. This training will provide useful skills for academic careers, non-academic careers and life situations outside of the workplace. Conflict resolution/negotiation skills are also relevant in managing issues in diversity, equity and inclusivity. We report our experience in developing this component of the training program, provide an overview of the approach to delivery and practice of skills, and provide an analysis of the reception and effectiveness of the training. Methods Evaluation of effectiveness of training used the principals of the Kirkpatrick Four Level Model of Evaluation. At the end of the course, students completed a questionnaire about their perceptions of training and were asked how they would respond to different scenarios requiring conflict resolution/negotiation skills. Several months later, students were surveyed to determine if they used some of these skills and/or witnessed situations where these skills would be useful. Results We report our experience in developing conflict resolution/negotiation training in our graduate curriculum, provide an overview of the approach to delivery and practice of skills, and provide an analysis of the reception and effectiveness of the training. The results suggest this training meets a need and is effective. Importantly, these materials provide a template for others wishing to implement similar training in their curricula. Conclusions Conflict resolution and negotiation training meets a need in graduate education. A mixed approach using didactic and interactive components spaced out over time appears to be an effective method of training.

. Consequently, new Ph.D.s are entering the workforce in non-tenure track academic positions, research positions in industry or government, teaching intensive and administrative positions, and other non-researchintensive positions [3,5]. Further, surveys of doctoral students suggest that a large percentage of trainees are interested in pursuing non-academic careers/nonresearch careers [6][7][8][9]. Reports from the National Institutes of Health and the National Academies of Science, Engineering, and Medicine recommend modification of graduate student training to prepare them for a broader range of careers [2][3][4]. These recommendations include increasing transparency of outcomes of graduate programs, increasing opportunities to explore different careers, and providing training in professional skills. Interestingly, a large survey of Ph.D. recipients indicates that similar soft/transferable skills are required by all Ph.D.s, regardless of their traditional or non-traditional career path, indicating that targeted training in these areas are beneficial for all Ph.D. candidates [5]. The NIH has broadly invested in this area via the BEST (Broadening Experiences in Scientific Training) program, which supported 5-year programs at 17 institutions to establish and disseminate best practices in career development and professional development [10]. The NIGMS has also introduced guidelines for modifications to training programs to incorporate career development and professional development activities [11].
Recommendations of desired professional skills competencies for doctorates have emerged from student surveys, employer surveys, committee reports, and workshops [4,5,9,[12][13][14]. A compilation of these recommendations is reported in Table 1. One competency is designed to address the NIH and NASEM recommendation to increase the opportunity for trainees to explore career opportunities (i.e. career planning/awareness). Many of the BEST programs have successfully created mechanisms to address career awareness and planning [15]. Some competencies obviously translate to important skills in a research-intensive scientific career, including communication, project management, and critical thinking, while others are comprised of a complex set of skills that are less obviously linked, such as leadership, managing others, and teamwork. A common thread to the latter competencies is personnel management and interpersonal relationships. Building relationships, managing difficult conversations, and dealing with conflict are specific skill sets underlying these competencies. In response to these recommendations, we have incorporated professional skills development into our firstyear biomedical sciences graduate curriculum (as part of a larger course), emphasizing these specific skill sets. A major emphasis in these sessions is conflict resolution and negotiation, skills that transcend these competencies. Herein, we describe our experiences in developing these sessions and offer a template for similar instruction.

Methods
The West Virginia University IRB approved the study. This study was partially retrospective and partially prospective. IRB approval numbers are WVU Proto-col#: 2001865972 and WVU Protocol#: 2004977501. Informed consent was in writing and all information was anonymous.
Evaluation of effectiveness of training was similar to recommendations by Denecke et al. [12], which align with the principals of the Kirkpatrick Four Level Model of Evaluation [16]. While originally developed as a tool for evaluation of human resources training, this evaluation model is widely used and has been adapted to assessment of higher education [17]. Upon completion of training, students completed a questionnaire about their perceptions of training (Level 1 evaluation -reaction) ( Table 2). This was constructed as a formative assessment of the training sessions. At the end of the semester, students were asked how they would respond to different scenarios requiring conflict resolution/negotiation skills to measure what they had learned (Level 2 evaluation -learning) ( Table 3). Several months later, students were surveyed to determine if they used some of these skills and/or witnessed situations where these skills would be useful, i.e. if their behavior had changed (Level 3 evaluation -behavior) ( Table 4). We have not attempted to evaluate the fourth level (results), which Table 1 List of professional skills competencies compiled from the literature

The timing of training sessions and surveys for workshops and classes is illustrated in Fig. 1. Responses to all of these surveys were anonymous. Therefore all of the analyses compared responses between individuals. The ten questions to evaluate learning in post-tests in 2019 and 2020, and to evaluate baseline knowledge in a pre-test in 2020, were independently scored by both instructors using a common rubric. The rubric was developed jointly by both instructors and they discussed how to score hypothetical answers prior to scoring the survey responses. Scores were averaged for statistical analysis. Brown-Forsythe and Bartlett's tests revealed homogeneity of variance between the samples. However, Shapiro-Wilks, Anderson-Darling, D' Agostina & Pearson and Kolmogorov-Smirnov tests for normal distribution revealed that these scores were not Gaussian and therefore a non-parametric statistic was used. The Kruskal Wallis H test and Conover and Dunn posthoc tests were used to evaluate differences between scores. (The Kruskal Wallis H test is the non-parametric equivalent of an ANOVA analysis.)

Exploring instructional platforms
The impetus to develop training in conflict resolution came from participation in the Train the Trainer Workshop sponsored by the Office of Intramural Training at the National Institutes of Health. Training in conflict resolution at WVU was developed and performed using two different formats: initially as a workshop and later as a classroom component of the formal first year curriculum. The number of attendees and respondents to surveys for workshops and classroom training are indicated in Table 5. Workshops were held over the course of two weeks as two ninety-minute sessions. The first workshop (October 2018) targeted trainees affiliated with T32 training programs and contained a didactic session followed by a role-playing session the following week. The second workshop (February 2019) targeted students in two biomedical science graduate programs (the Biochemistry and Molecular Biology and Clinical and Translational Sciences Graduate Programs) and consisted of two mixed sessions containing didactic and role-playing components. The role-playing exercises utilized real situations of faculty-student conflict, solicited from faculty and students at WVU. While the workshops were well received, student commitment to participation flagged as the number of participants was significantly less than the number of students registered to participate. Anecdotal evidence from discussion with students who participated in the workshops suggested that training in conflict resolution would be useful to all graduate students and that training early in the curriculum would be most beneficial. Conflict resolution was incorporated into a professional skills development component for the first-year graduate curriculum for fall 2019. The professional skills development component of the first-year curriculum was designed to include didactic/ interactive sessions on communication, lay communication, resilience, networking, working in teams/collaboration, conflict resolution, and negotiation (Table 6). Interestingly, six of the nine topics covered in our Professional Skills session were also incorporated in the URBEST Program's Leadership and Management for  Scientists at the University of Rochester [18]. Each session was 50 min in duration. We also offer a 1-credit course with identical content that runs concurrently for students not enrolled in this curriculum, including more senior students and students from other departmental programs. Through this mechanism, a broader impact upon the graduate programs at WVU is anticipated. Conflict resolution was a central theme of these sessions, since these skills crossed a number of recommended professional skills competencies, including leadership, project management, teamwork, collaboration, and managing others. Negotiation, which shares many concepts with conflict resolution, was also incorporated. Our philosophy is to use collaboration to resolve conflict constructively and to use principled negotiation strategies. Each session was a mixture of didactic presentation of concepts interspersed with interactive/role-playing activities. Distribution of the sessions over seven weeks was intentional to reinforce concepts and engage in role-playing over an extended period of time to promote changes in the participants' behavior in conflicting situations. A conflict resolution workshop at Michigan State University is not part of the formal curriculum, but is similarly extended over six sessions [19]. This strategy is based on the concepts of retrieval learning (role playing), spacing out practice (over multiple sessions), and varying practice (interleaving conflict resolution and negotiation) as effective methods of learning [20]. The Fall 2020 iteration of the course utilized a virtual format, due to the COVID-19 pandemic.

Organization of conflict resolution/negotiation sessions
The conflict resolution/negotiation sessions were comprised of four components interspersed throughout the session. The first was didactic, where concepts, strategies, and tactics for managing conflict/negotiation were presented to the students. The second was interactive, where the students contributed to in-class discussion using online polling tools. The third was an illustration of a relevant situation acted out by the instructors. These were first done to demonstrate the 'wrong' way to manage the situation and how this approach could spiral out of control. The situation was acted out a second time demonstrating a specific strategy or tactic to manage conflict in that scenario. The fourth component was role-playing by the students. The scenarios for role-playing were solicited from students and faculty at the Health Sciences Center at WVU and were drawn from their actual experiences. These activities provided an opportunity to practice specific conflict resolution skills and the student playing the 'opponent' in the exercise was given specific instructions to resist. The role-playing activities were considered important to begin training the students to modify their behavior to improve their ability to resolve conflict. Active learning activities like these are frequently utilized in professional education workshops providing training in conflict resolution [21][22][23][24]. Each of the sessions was designed to deliver a few lessons related to conflict resolution/negotiation and some skills for students to learn to manage conflict ( Table 7). The lessons and skills were developed from a number of sources (Table 7). The first sessions focused upon basic skills and subsequent sessions built upon these skills to elaborate on more complex scenarios, strategies, and tactics. When transitioning to the negotiation sessions, twenty-four concepts from conflict resolution were briefly reviewed, as these were also essential concepts for successful negotiation ( Table 8). The interactive exercises with the class were interspersed with the didactic parts of the lectures. One example is an activity used in a session about emotions in conflict, where strategies to reframe emotions and defuse the opponent's emotions are discussed. In the exercise, "scenes from a hat", one student draws an inflammatory statement (authentic statements heard by and solicited from graduate students) from a hat and reads the statement to another student. For example, "Why don't you ever help out with laboratory grunt work? You always use up all the reagents and you never make them! I am so sick of this!". The other student responds quickly to reframe this personal challenge to focus on the underlying issues, rather than on the persons involved. For example, "You are right that there is an issue of keeping common reagents stocked. Perhaps we could discuss ways to work as a team to restock. " A second example of using interactive activities to develop concepts come from the first session of negotiation, which covers the topics of preparing for negotiations, thinking outside the box and developing a strong BATNA (best alternative to a negotiated agreement). At the beginning of the session, the students are asked to assume the role of an Assistant Professor whose boss has just asked them to take on the role of Director of Graduate Studies. The students are polled anonymously for their opinions of the pros and cons of taking the position. Responses were projected in real time, providing the students insight into the thoughts of their colleagues and providing collective lists. The session then moved into a didactic component discussing preparation and performing research prior to the beginning of a negotiation. The students were then anonymously polled for factual information they would like to collect. The session returned to a didactic discussion of interests and inventing options. Finally, the students were polled for concessions they could ask for in return for taking on this assignment. Most of the responses from the students were thoughtful and reasonable, suggesting they took the opportunity to seriously work through the exercise. The role-playing exercises were very important components of these sessions. The demonstrations by the instructors were very well received by the students. These were semi-scripted to ensure that the exercises properly illustrated the points intended. One effective demonstration addressed managing your emotions and regaining control under difficult circumstances. The scenario  demonstrated the interaction between a critical faculty member and a student making a public presentation. As the faculty member continues to criticize, the student responds emotionally, either withdrawing or lashing out at the faculty member. The demonstration continues after the student lashes out to illustrate how the student can regain control by apologizing for the outburst and turning the attack of the faculty member, e.g. "From your comments, I can see that there may be additional considerations that you could help me with. Perhaps we could meet and discuss these issues at a later date rather than in the middle of my presentation. "What is the purpose of this policy?", "Who created this policy?", "Why not modify the policy to take into account this situation?". Illustrating different examples by demonstration provides an alternative to didactic presentation of the concepts. Perhaps the most important and best received exercises were the role-playing activities for students, since this provided them the opportunity to practice different approaches in conflict resolution and negotiation. These activities were designed to practice the specific skill sets covered in class and the 'opponent' in the discussion received instructions to resist and raise objections to extend the opportunity to practice different skills. Many scenarios were developed for the workshops and the class. The scenarios utilized for conflict resolution exercises are shown in the supplemental material. During these exercises, the instructors circulated among the students to observe their interactions, identify good examples to point out to the class, and provide suggestions if the students were struggling. Immediately following the exercise, the class and instructors discussed statements and approaches from the exercise that appeared impactful.

Incorporation of microaggression
The conflict resolution sessions contain strategies for engaging in difficult conversations and some of these concepts are very relevant to managing difficult conversations around diversity equity and inclusion (DEI). The negotiation sessions contain strategies to deal with tricky or challenging bargaining tactics and include strategies to counter demeaning, exclusionary, undermining and harassing behavior during negotiations. In the Fall 2020 version of the course, a conflict resolution discussion on microaggression was implemented. Public service announcements from MTV and YouTube videos were used to illustrate examples of microaggression that were discussed as part of the class. The frequent benign intent of microaggressive statements was contrasted with the detrimental impact upon the recipient of the comment. Strategies to respond to microaggressions, by both the recipient and a bystander were presented. Students were asked to reflect on microaggression and write about a fictional incidence of microaggression explaining how the recipient might respond and how a bystander might respond to the microaggression.

Effectiveness of Training Student reception of the workshop/course
Upon completion of the workshops, students were requested to take an online, anonymous survey. Approximately 3 weeks after completion of the conflict resolution/negotiation sessions in the first-year curriculum, the students were asked to complete an online, anonymous survey to measure their reception of the sessions. The workshop survey contained five statements related to the objectives and activities of the workshop, and the professional skills development course included three additional statements related to the negotiation sessions ( Table 2). Participants were asked if they agreed with the statements using the Likert scale to indicate strength of agreement (5 = strongly agree) or disagreement (1 = strongly disagree). The results are shown in Fig. 2. The students were largely in agreement that the workshop/course provided new information, helped them prepare for conflict and negotiation, provided insight into their approach and others approaches to conflict, and provided useful strategies for use in the future. The average scores were remarkably uniform across the different iterations of these sessions. The reaction of students to these sessions suggest that they provide new information about conflict resolution/negotiation and some preparation for managing conflict and negotiating in the future. An interesting observation is the lowest Likert scores on these surveys related to the usefulness of the role-playing activities in preparation for conflict resolution and negotiation. The students were also asked to describe the best part(s) of the workshop/professional skills sessions (Table 9). Given the numerical response to the statement about the usefulness of role-playing (Fig. 2), it was surprising that the students overwhelmingly indicated that this was the best part of the course. Distant seconds in the students' responses including watching simulated arguments/negotiations, the didactic content and learning about personal approaches to conflict.
Students were also asked to make suggestions for improvement for the sessions, although there was little consensus. These are presented in Supplemental Table 1 for consideration for modification and development of similar activities.

Student learning in the course
As part of the survey to evaluate student reception of the course, the students were also asked ten questions to determine if they retained specific concepts on conflict resolution and negotiation (Table 3). This was not a formal test, was administered anonymously and the students were instructed that there was no need to study in advance. The intent was to measure the quality of information that they retained from the training sessions and not their ability to master the subject for an exam. Both instructors used a common rubric to grade each student's responses. The scores of the two instructors were averaged.
After completion of training in fall 2019, the students exhibited knowledge of strategies to manage conflict of interest and negotiation (mean score = 7.3 ± 2.1, median = 8) (Fig. 3). After completion of training in fall 2020, the students scored lower on the assessment than the preceding cohort (mean score = 4.9 ± 2.1, median = 5). In fall 2020, a pre-test, which was identical to the post-test, was incorporated (mean score = 2.3 ± 1.6, median = 2) (Fig. 3). The distribution of scores on each exam was not Gaussian and a non-parametrical statistical  Table 2) on the Likert scale. Questions Q1 to Q5 were related to conflict resolution and questions Q6 to Q8 were related to negotiation. The average score ± standard deviation is plotted.

As the goal of the training was to prepare students to better manage conflict and negotiation, overall performance in these evaluations is encouraging and suggests that these training sessions may have been effective.

Impact on the students -after the fact
Students were surveyed in March 2020 to determine if training in conflict resolution/negotiation had altered their behavior or attitude towards conflict resolution. This survey was 18 months after the first workshop, 13 months after the second workshop, and 5 months after the conflict resolution/negotiation sessions in the professional skills development class. All registrants/ participants in the workshops who were still registered at WVU and all students who had taken the professional skills development class were surveyed. The survey consisted of three questions (Table 4), with a follow up to each to elaborate on the concepts from class that were relevant to the situation if the respondents answered in the affirmative. Students matriculating in Fall 2020 were surveyed in March 2021. The overall response rate for the surveys was 57.5%. The majority of students who took a workshop had used concepts from the workshop in resolving conflicts and all of the students had observed scenarios where they felt that concepts from the course could have been applied (Fig. 4). All of the students indicated an intent to utilize conflict resolution concepts in the future. The students who took the professional skills development sessions as part of the first-year curriculum were more junior than those who took the workshops, and there was less elapsed time between the conflict resolution sessions and the survey. The majority of these students had used concepts from the course and had observed situations where concepts could have been used (Fig. 3  B and C). Most of the respondents stated their intention to use some of the concepts in future conflicts. While other influences upon students' management of conflict cannot be excluded, these results are consistent with modified student behavior in response to training in conflict resolution.

The other side of the equation -faculty training
In addition to providing conflict resolution training to graduate students, we have also conducted workshops on conflict resolution for faculty. These were single 60-to-90-min sessions introducing some of the key concepts in conflict resolution and included interactive sessions designed to meet the needs of the group. In a mentor training workshop for faculty preceptors of doctoral students the interactive exercises focused upon conflict resolution and approaching difficult conversations with trainees. In a workshop for women in science, the interactive exercises provided practice in conflict resolution with trainees and with senior faculty in positions of authority. In a combined workshop for faculty and staff, the exercises addressed faculty and staff issues to provide practice in defusing conflicts in the presence of a real or perceived power differential. The role-playing scenarios created for these sessions are described in the supplemental material. These single sessions were not expected to change the behavior of the participants, but served to raise awareness of approaches to manage conflict.  Table 3) to evaluate their knowledge of concepts and skills presented in the training sessions. A post-test was administered after the Fall 2019 and Fall 2020 iterations of the sessions and a pre-test was administered before the Fall 2020 sessions. The tests were scored independently by the two instructors using a common rubric. The test scores are presented as a box and whisker plot. The outlier in the Post 2019 test is indicated by a circle. The distribution of scores for each exam was non-Gaussian. The results were analyzed using the Kruskal Wallis H test (H = 85.97, p < 0.0001). Conover and Dunn posthoc tests were performed and indicated that the scores of each of the three tests were different

Discussion
The intent of our conflict resolution training is to provide students the strategies and skillset to successfully navigate conflict. Role-playing scenarios focus on academic scenarios to prepare students for situations they may encounter in the short term with co-workers and mentors. However, these skills transcend professional boundaries as illustrated to the students by examples presented in the didactic portion of training and are useful in real life, non-professional situations. Further, this training provides a framework for managing difficult conversations around DEI. The use of empathy and active listening are important for difficult conversations and strategies to reframe and defuse emotions aid in managing emotional conversations. Strategies to redirect verbal attacks and reframe personal challenges provide responses to microaggression. Issues associated with DEI are broad and complex and training in conflict resolution addresses only a small component of training in DEI. As such, these sessions will serve to complement other, more comprehensive programs to educate students faculty and staff about DEI issues.

Reception and effectiveness
Uniformly, across the platforms, the students felt that these sessions provided them with new information on the topic and strategies to manage conflict and negotiate. The results of these surveys suggest that these sessions are meeting the needs of graduate students. Similarly, surveys of clinicians/residents about graduate medical education leadership training demonstrate a need for instruction in the effective management of conflict and navigating difficult conversations [35,36]. The results of studies to evaluate the effectiveness of conflict resolution training in higher education are mixed. In a graduate student conflict resolution workshop that extended over 6 sessions, the TKI and the Putnam-Wilson Organizational Communication Conflict Instrument (OCCI) were used to evaluate changes in student approaches to conflict. The pre-and post-tests were administered 10 weeks apart and the results showed a trend toward a change in approach to a cooperative style of conflict management, however the difference was not statistically significant [19]. Implementation of a conflict resolution program for graduate students and faculty in a new graduate program was evaluated by surveys and focus groups and appeared to have a positive impact upon conflict management by participants [37]. A two-day conflict resolution workshop for residents and medical school faculty was evaluated by surveys and a long term follow up using focus groups 12 to 18 months after the workshop [38].
The results suggest that training had an impact over the short term and importantly that elements of the training were incorporated by participants in their professional lives. Our results suggest graduate student trainees gain concepts to manage conflict from the training sessions, based upon post-test results, and that the students recognize situations where specific strategies can be applied to manage conflict months after completion of training. It is also encouraging that almost all the survey respondents indicated an intent to apply knowledge from the conflict resolution/negotiation sessions in the future.

Workshop vs class
The first iteration of our conflict resolution sessions was delivered in a workshop format comprised of two 1.5-2 h sessions with a mixture of didactic and interactive content. Incorporation of these sessions into the graduate curriculum accomplished three goals: 1) achieving broader delivery to the graduate student population, 2) delivery of the material earlier in the graduate student program and 3) extending delivery over a longer time frame. Analysis of the Michigan State University conflict resolution workshops revealed several studentidentified limitations, including training a narrow cohort of students who participate in the voluntary workshops and training later, rather than earlier, in the graduate student career [19]. By extending delivery and incorporating negotiation, which shares a number of skills with conflict resolution, the exercises required retrieval practice and spaced-out practice of skills, two effective methods to promote learning and incorporation of new skills into behavior [20].

What worked?
In both the workshop format and classroom format, students identified observing the role-playing exercises by the instructors as one of the strengths. These exercises were designed to illustrate important points or strategies and typically an example demonstrating an "incorrect" approach was illustrated by the instructors, followed by a second demonstration of a better approach using a strategy discussed in class. This method contrasted the two approaches and emphasized the differences by providing a clear example of the benefits of adopting the strategies presented in the course. The role-playing exercises were viewed as a strength in both the workshop and traditional course format. Many students also suggested more role-playing activities would improve the course. This contrasted with a subset of students with the opposite view, that role-playing in the course should be reduced. We believe the difference reflects the comfort level of different students in role playing exercises. Likewise, in a recent survey of residents, role-playing was the least desired format in training in conflict resolution and managing difficult conversations [35]. While there are some limitations in roleplaying, e.g. the interaction is artificial and it is difficult to simulate a power differential [39], most conflict resolution training utilizes role-playing [22]. Further, handson training and practicing skills in context are important and effective approaches in learning [20,39].
An effective method to generate student engagement was real time polling. In the classroom, real time polling was used for brainstorming to create a list of options and this effectively translated into the virtual format via zoom in the chat feature. For example, in the negotiation portion this strategy was used to allow the students to explore the pros and cons of an Assistant Professor taking on the role of Director of Graduate studies and then preparing a list of requests they might make during negotiation with their chair. This exercise illustrated preparation for negotiation and thinking creatively in advance of negotiation.

What didn't work?
The role-playing exercises for conflict resolution were all designed based upon real situations experienced by our graduate students and were broadly characterized as conflicts with mentors or conflicts with peers. These engaged the students with relatable exercises for situations they may face during their graduate career. Negotiation exercises were initially more challenging. The first iteration used a negotiation scenario between teams of "students" and teams of "faculty/administrators" to negotiate a new contract between the university and the student's union. The expectation was that the students would be engaged in discussing student issues, but this exercise was very ineffective. The second iteration used a negotiation scenario where the student played a junior faculty candidate negotiating with a departmental chair. Throughout the three sessions of the course on negotiation, students worked with each other to prepare for their negotiation. The final negotiation occurred between the students and a faculty member. Three current chairs, two ex-chairs and two senior faculty in administration played the role of chair in the simulation. This exercise also provided a unique networking opportunity for the students. A number of students identified this exercise as a strength of the course in Fall 2020.

In-person vs Virtual delivery
Transitioning to a virtual method of delivery during the pandemic provided some challenges. With the exception of the chat and some discussion, the format dampened the interactive nature of these sessions. Demonstrations by the instructors lacked the nuances of body language, potentially reducing the impact of illustrating different approaches to one issue. The role-playing exercises became more challenging. In the classroom, assigning roles was straightforward and instructions were provided on handouts. In the virtual format, more coordination was required and fewer instructions could effectively be delivered. In the classroom, instructors circulated around the room to monitor role playing and identifying pieces to utilize during de-briefing. The role-playing sessions in the virtual classroom were performed in breakout rooms and the movement of instructors into and out of the breakout rooms delayed progression through the class and reduced the number of interactions monitored by the instructors. In the workshop format and the Fall 2019 version of the in-class course, role playing was identified as a major strength of the course by the vast majority of the respondents to the course evaluation survey.
In contrast, only one-quarter of the students in the Fall 2020 class stated that role playing was a major strength.
These results suggest that the instructors' perception of the shortcomings of role playing in the virtual classroom was shared by the students.

Limitations
The evaluations of reaction, learning, and behavior were survey-based. The response rate for level 1 and level 2 were high (87% and 100% for the two iterations of the classroom based sessions), but the response rate for level 3 was lower (63% and 68%). While most of the respondents to the level 3 survey appeared to be aware of conflict resolution strategies and had applied or understood how to apply these strategies in a conflict they observed, the sample may not be truly representative. It is possible that trainees who had not incorporated these strategies into their management of conflict were predominant among the non-respondents and that the survey results overrepresent trainees who utilized or at least recognized situations to apply these concepts. In fall 2020, when the pre-test and post-test were conducted, there was a drop in respondents to the post-test. The post-test result sample may not be truly representative of the entire cohort of trainees. There are also inherent limitations to the Kirkpatrick model, particularly in level 3 and level 4 evaluations since additional factors besides training might impact behavior and results [40].

Implementation of conflict resolution/negotiation training
The key to implementing a successful conflict resolution training program is the commitment of the faculty and administration. Expertise or previous training in conflict resolution would be an asset, but is not essential providing the faculty are willing to learn. In this case, participation in a workshop like the Train the Trainers Workshop sponsored by the Office of Intramural Training at the National Institutes of Health and consultation with experts in conflict/mediation would be useful. Professor William Rhee, a mediation expert in the WVU School of Law, facilitated our first workshop. An investment of time to research and collect material for presentation is required. This is comparable to preparation of a lecture in your general field, but outside your area of expertise. Additional time and effort are required if roleplaying scenarios and other activities need to be developed. Our training sessions utilize two committed faculty members providing the opportunity for role-playing demonstrations. Additional individuals, either faculty or students who had already participated in a workshop or the class, also helped facilitate role-playing. For a group of thirty students, three or four individuals could facilitate the role-playing activities. In addition, breaking into groups of three where two students play roles and the third functions as an observer is also an effective strategy to facilitate discussion during debriefing after the role-play. The primary cost associated with implementing a conflict resolution program is faculty and staff time to develop and deliver the program.

Future directions
During the development and implementation of this program three different formats were employed, partly by choice and partly dictated by circumstance. While we did not set out to evaluate the effectiveness of different training formats, each may fulfill different needs in future. The classroom format provides more opportunities for simulations, which is an important mechanism to reinforce concepts and adapt behavior. The workshop format may be desired by individuals with limitations on their time precluding participation in a longer course (e.g. faculty and staff ). The virtual format provides an opportunity for remote instruction on conflict resolution. Our experience revealed limitations on interactions in the virtual format, but these could be overcome by adapting additional mechanisms. The chat feature provided effective interaction and additional platforms allowing real time sharing of notes or ideas might be employed. Additional strategies employing reflective exercises and/or journal activities could also be incorporated. Regardless of the format, we believe that this curriculum is valuable to trainees and are encouraged that our observations appear to indicate that training is effective.
