Professional values among nursing students: a systematic review and meta-analysis

Every profession has a hidden compass, a set of unwritten rules that guides how its members think, act, and treat others. For nurses, this compass is made of professional values: the deep-seated beliefs about caring for patients, acting with honesty, treating everyone with fairness, and taking responsibility for their work. These values are not just abstract ideas; they are the foundation that helps a nurse decide what to do in a difficult moment, how to speak to a frightened family, and how to maintain dignity in a chaotic hospital. Because these values shape the quality of care patients receive, educators spend years trying to instill them in nursing students. But a question has lingered over the field: just how well is this teaching working? Do students entering the profession actually hold these values, and does that belief change as they learn more?

To answer this, a team of researchers from Chengdu University of Traditional Chinese Medicine set out to look at the big picture. Instead of relying on a single study from one hospital or one country, they gathered evidence from across the globe. They collected data from 72 different studies conducted in 18 countries, involving more than 32,000 nursing students. By combining these separate pieces of research, they could see patterns that a single study might miss. They focused specifically on how students scored on standard tests designed to measure professional values, looking for the average level of these values and trying to understand why some groups scored higher or lower than others.

The researchers found that, overall, nursing students hold a relatively positive view of their profession's values. When the scores from all the different studies were combined, the average result suggested that students generally embrace the core principles of nursing, such as trust, justice, and activism. This is a reassuring sign that the current system of nursing education is successfully helping students internalize the ethical framework they will need as future professionals. The study suggests that through classroom learning, interactions with teachers, and early clinical experiences, students are gradually adopting the mindset required to provide safe and compassionate care.

However, the story is not entirely uniform. The researchers discovered that the numbers varied significantly depending on where the students were from and which specific test they took. The most common tool used to measure these values was a revised version of a scale called the Nurses Professional Values Scale, but there were also older and newer versions in use. When the researchers compared the results, they found that the type of test mattered; students taking the newest version of the test tended to get higher scores than those taking the older versions. This suggests that the way a question is asked can change the answer, and it highlights the need for consistency in how these values are measured.

Perhaps the most striking finding was a clear trend over time. The researchers noticed that students in more recent studies tended to have higher scores than those in studies from a decade ago. This upward trend suggests that nursing education is not just maintaining the status quo but is actually improving in its ability to foster these values. It appears that as the years pass, the curriculum and the environment of nursing schools are becoming more effective at helping students connect with the ethical heart of their future profession.

The study also pointed out that culture and location play a major role. Students in different countries showed different levels of these values, which implies that local traditions, educational systems, and social environments shape how students understand their role. For instance, the way a student in one country learns about "caring" might be influenced by their specific cultural background, leading to different scores on a global test. This does not mean one group is better than another, but rather that the path to developing professional values is influenced by the world the student lives in.

Despite these positive findings, the researchers were careful to note that their work has limits. Because they looked at studies that captured a single moment in time, they could not prove that education causes the values to change; they could only see that students with more education often had higher scores. They also relied on students answering questions about themselves, which can sometimes be influenced by a desire to give the "right" answer rather than reflecting their true feelings. Nevertheless, the sheer size of their review, covering thousands of students from many nations, gives a strong and reliable picture of the current state of nursing education.

The takeaway for those teaching the next generation of nurses is clear. While students are starting with a good foundation, educators should not assume the job is done. The study suggests that teaching professional values should not be confined to a single class or a specific year of school. Instead, these lessons should be woven into every part of the curriculum, from the first day of theory to the last day of clinical practice. By creating environments where students can practice these values in real situations and reflect on them, educators can help ensure that the compass guiding these future nurses remains steady and true, no matter where they practice.
