Development and Psychometric Evaluation of the Boundary-Spanning Role Strain Scale for Clinical Nursing Instructors

In the world of nursing education, a unique group of professionals stands at the crossroads between two very different worlds: the academic halls of universities and the high-pressure corridors of hospital wards. These are the clinical nursing instructors, educators employed by schools who spend their days teaching students in external medical facilities. Because they work for one organization while living and working inside another, they occupy what experts call a "boundary-spanning" role. This position is inherently complex. They must translate the priorities of the university into the daily reality of patient care, often while navigating conflicting expectations from their employers and the hospital staff who host them. Just as a bridge must bear the weight of traffic from both sides while remaining anchored to its own foundations, these instructors must balance the demands of teaching with the urgent needs of a clinical team, all while trying to maintain their own sense of professional identity and belonging.

When the pressure of these dual worlds becomes too heavy, it creates a state known as role strain. This is not simply the feeling of being tired from a long shift; it is a deeper, more specific kind of stress that arises when a person's job expectations feel unstable, unclear, or impossible to meet. For decades, researchers have known that people working across organizational lines face higher levels of stress than those who stay within a single system. However, until now, there has been no reliable way to measure exactly what this strain looks like for nursing instructors. Existing tools were designed for teachers who stay on campus or for nurses who work entirely within a hospital, leaving a blind spot for those who bridge the gap. Without a clear way to measure the problem, schools and hospitals cannot effectively fix it, potentially leading to burnout and a shortage of the very educators needed to train the next generation of nurses.

To fill this gap, researchers Yong-Zih Lin and I-Ju Chen set out to build a new measuring tool specifically for these boundary-spanning instructors. They began by looking at the existing literature and observing the daily lives of instructors working in external clinical settings. They realized that simply adapting an old survey meant for university faculty would not work, because it missed the unique stresses of working in a hospital that does not employ you. The team gathered a group of seven experts in nursing education to review their initial list of questions, refining the wording until every item clearly captured the specific tensions these instructors face. This process ensured that the questions were relevant and clear, resulting in a draft survey that was ready to be tested.

The researchers then invited 203 clinical nursing instructors to complete this new survey. Every participant was a woman working full-time as an instructor in an external hospital, with at least two months of experience in the role. The group represented a wide range of ages and experience levels, working in various departments from internal medicine to pediatric wards. As the instructors answered the questions, the researchers analyzed the data to see if the survey held together logically and if it consistently measured the same things over time. They looked for patterns in the answers to see if the questions naturally grouped themselves into distinct categories of stress, much like how a cluster of stars forms a recognizable constellation in the night sky.

The analysis revealed that the survey, which they named the Boundary-Spanning Role Strain Scale, successfully captured five distinct types of strain that these instructors experience. The first and most common type was role overload and work-related exhaustion, reflecting the sheer volume of work, time pressure, and lack of resources that leave instructors physically and emotionally drained. The second type was role identity and professional recognition strain, which described the pain of feeling like an outsider in the hospital, where their teaching expertise is often overlooked or undervalued by the clinical staff. The third category involved role goal ambiguity and incongruity, capturing the confusion that arises when the school and the hospital send mixed or contradictory messages about what the instructor should be doing.

The fourth dimension identified was role competence and evaluation uncertainty. This reflected the anxiety instructors feel when they are unsure if they are good enough at their job or when they worry that their skills do not match the rapidly changing demands of the medical field. Finally, the fifth dimension was role adaptation demands and boundary-spanning conflict. This specific type of strain highlighted the difficulty of constantly shifting between two different cultures, policies, and sets of rules, and the friction that occurs when trying to fit into a team where one is not a permanent member. The survey proved to be a reliable tool, with the questions consistently grouping into these five areas and showing strong internal consistency, meaning the instructors answered the questions in a way that made sense as a whole picture.

The findings suggest that the stress these instructors face is far more complex than just having too much to do. While heavy workloads are a significant part of the problem, the study shows that the lack of professional recognition and the struggle to adapt to two different institutional cultures are equally powerful sources of strain. The researchers found that these instructors often feel like "guests" in the hospitals where they teach, a status that can erode their sense of belonging and legitimacy. The study explicitly rules out the idea that a generic stress survey is sufficient for this group; the unique interorganizational nature of their work requires a tool that specifically asks about recognition, adaptation, and conflicting expectations.

The authors are confident in the reliability of their new scale, having tested it with a substantial group of instructors and confirmed that it produces stable results. However, they note that the study was limited to a single country and included only female participants, which means the findings might look slightly different in other parts of the world or with a more diverse group of instructors. They also point out that while the survey structure is solid, future research should use different statistical methods to confirm the five categories in even larger groups. Despite these limitations, the study provides a clear, evidence-based way to understand the hidden burdens of clinical nursing instructors.

By giving schools and hospitals a way to measure these specific types of stress, the new scale offers a path toward better support. Instead of guessing what is wrong, administrators can now use the results to identify exactly where the friction lies. They can see if an instructor is struggling because of too much work, or because they feel unrecognized, or because the rules from the school and hospital do not match. This clarity allows for targeted solutions, such as creating better communication channels between the two institutions, clarifying job expectations, and ensuring that instructors are treated as valued members of the clinical team. Ultimately, understanding and addressing these strains is not just about helping the instructors; it is about securing the future of nursing education by ensuring that the people who teach the next generation of nurses can do so without being worn down by the very system they are trying to navigate.
