Comparing Virtual Reality CAVE and Simulated Home Experiences on Self‑Perceived Clinical Competence, Self‑Confidence, and Satisfaction in Community Health Nursing: A Crossover Randomized Controlled Trial
This crossover randomized controlled trial demonstrates that while traditional simulated home environments initially yielded higher gains in self-perceived clinical competence, VR CAVE simulations ultimately achieved comparable efficacy in enhancing nursing students' clinical competence, self-confidence, and satisfaction, with the VR modality showing marginally higher learner engagement.

Imagine you are training to be a superhero, but instead of fighting aliens, your mission is to care for people in their own homes. This is the world of community health nursing, a field where nurses visit patients in apartments, houses, and tiny flats to help them manage illnesses like asthma or infections. But here's the tricky part: you can't just practice on real people right away. It's too risky, and there aren't enough real homes to practice in. So, schools use "simulations"—fake scenarios where students act out their skills.
For a long time, the best way to practice was to walk into a room built to look exactly like a messy apartment, complete with fake furniture and actors playing patients. It's like a theater set for doctors. But technology has opened a new door: Virtual Reality (VR). Specifically, there's a cool setup called a "CAVE." Instead of wearing a headset that blocks out the world, you stand in a room where the walls themselves become a giant, 3D movie screen. You can walk around, look up, and see a virtual home projected all around you, making it feel like you're actually inside a patient's living room. The big question for educators is: Does this high-tech, wall-sized movie work as well as the old-school, physical fake apartment? Does it make students feel more confident and skilled, or is the physical room still the champion?
This study, led by a team of researchers from universities in Hong Kong, decided to put these two training methods to the ultimate test. They didn't just guess; they ran a massive experiment with 150 final-year nursing students. Think of it as a "training camp" where every single student had to try both methods. First, half the group practiced in the high-tech VR CAVE while the other half practiced in the traditional fake apartment. Then, after a three-week break to let their brains reset, they swapped places. The group that started with VR tried the fake apartment, and the group that started with the fake apartment tried the VR.
The researchers were looking for three things: Did the students feel more skilled (clinical competence)? Did they feel braver (self-confidence)? And did they enjoy the training (satisfaction)? They measured these feelings before the training, right after the first session, and again after the second session.
The results were a bit like a race where the runners started at different speeds but finished with the same time. When the students first tried the traditional fake apartment, they felt a huge jump in their skills—so much so that they felt significantly more competent than the students who started with the VR. It was as if the physical room gave them an immediate, tangible boost. However, once everyone had experienced both methods, the gap disappeared. By the end, the students who started with VR and the students who started with the fake apartment were equally skilled and confident. The study suggests that while the physical room might give a quick start, the VR CAVE is just as effective at teaching the necessary skills in the long run.
Interestingly, the students seemed to have a slight preference for the VR experience. Even though their final skill levels were the same, they reported feeling slightly more satisfied and confident after the VR sessions. They loved the immersion, describing it as a way to really "step into" the patient's world. The study concludes that the VR CAVE is a powerful tool that can match the effectiveness of traditional training. It's not a magic wand that makes you an expert overnight, but it is a fantastic, engaging way to learn, offering a level of excitement and realism that might make students more eager to learn their life-saving skills.
