Measuring How Students Rely on Generative AI in Academic Writing: Development and Multi-Source Validation of the Generative AI Reliance Types Scale (GenAI-RTS)
This study presents the development and multi-source validation of the 20-item Generative AI Reliance Types Scale (GenAI-RTS), a psychometrically sound instrument that identifies four distinct reliance profiles among undergraduates and demonstrates measurement invariance across diverse student demographics.

Imagine the classroom as a giant, bustling workshop where students are building complex structures out of words. For decades, the only tools available were pencils, erasers, and the students' own brains. Then, a new, incredibly fast, and chatty robot assistant arrived. This robot, known as Generative AI (or GenAI), can write sentences, fix grammar, and even brainstorm ideas in the blink of an eye. Suddenly, almost everyone in the workshop is using it.
The big question used to be simple: "Are you using the robot?" But now that nearly everyone is, that question is like asking, "Are you breathing?" It doesn't tell us much about how a student is actually learning. The real mystery is: How are they using it? Are they the master architects, using the robot to test ideas and polish their blueprints? Or are they the sleepwalkers, letting the robot build the whole house while they just watch? This paper is about building a new "ruler" to measure exactly how students lean on this digital helper, because the way they use it changes whether they actually learn or just get the job done.
The New Ruler for Robot Helpers
Meet the GenAI-RTS. Think of this as a special 20-question quiz that researchers created to take a snapshot of how students rely on AI when writing essays. Before this study, we didn't have a good way to tell the difference between a student who uses AI as a smart tool and one who uses it as a crutch. The researchers at the University of Maryland and the University at Buffalo wanted to build a ruler that could measure four different "personalities" of AI use:
- The Strategist: The student who plans everything carefully, checks the robot's work, and only uses it when it fits their plan.
- The Tool-User: The student who uses the robot for quick, surface-level tasks, like fixing a typo or rephrasing a sentence, but does the heavy thinking themselves.
- The Dependent: The student who hands over the whole job to the robot, accepting whatever it says without asking "Is this true?"
- The Conversationalist: The student who treats the robot like a debate partner, bouncing ideas back and forth to build something new together.
The Great Detective Work
To build this ruler, the researchers didn't just guess. They started with a theory, like an architect drawing a blueprint before laying a single brick. They wrote 25 questions based on how humans learn and how we think, then asked 382 college students to fill out the survey. They also sat down with 14 students for deep chats to see if the questions actually made sense to real people.
Here is what they found, and it's a bit more complicated than a simple "good vs. bad" list:
1. The "Strategist" is actually two different things.
The researchers thought "Strategic" reliance was one big category. But the data showed it's actually two separate skills that don't always go together. Some students are great at Critical Evaluation (checking if the robot is lying or making mistakes), but they aren't necessarily good at Deliberate Use (planning ahead to use the robot only when needed). It's like having a great security guard but a poor traffic planner. The best model for the ruler turned out to have five sections instead of the original four, separating these two skills.
2. The "Tool-User" and "Conversationalist" are different, even if they look similar.
These two groups both talk to the robot a lot. But the study proved they are doing different things. The Tool-User is just trying to get a sentence polished, while the Conversationalist is using the robot to explore new ideas. Even though they often score high on both, the ruler can tell them apart, and they actually produce different results in their writing.
3. The "Dependent" group is tricky.
The study found that students who admitted to being "Dependent" (letting the robot do all the work) often talked about it as something they used to do, not something they do now. This suggests that when students fill out surveys, they might be hiding their true habits because they feel guilty. The ruler might be underestimating how many students are actually leaning too hard on the robot.
4. The ruler works for everyone (mostly).
One of the most exciting findings is that this ruler works the same way for different groups of people. Whether a student is a guy or a girl, a first-generation college student or not, or studying science (STEM) or art, the questions mean the same thing to them. This is a big deal because it means we can fairly compare how different groups of students use AI without the ruler being biased.
5. The ruler needs a tiny tweak.
The researchers noticed that the 7-point scale on the survey (where 1 is "Strongly Disagree" and 7 is "Strongly Agree") was a bit confusing. Students kept skipping the middle option ("Slightly Disagree") and jumping straight to "Disagree." It's like having a thermometer with too many tiny lines in the middle that nobody can read. The study suggests that a 5-point scale would be much clearer and easier for students to use.
What This Means for the Future
This paper doesn't tell us to ban robots or force everyone to write by hand. Instead, it gives teachers and researchers a better way to understand the story behind the AI use.
If a student is a "Strategist," they are likely learning a lot because they are in control. If they are "Dependent," they might need help learning how to think for themselves again. The most important takeaway is that how you use the robot matters more than if you use it.
The researchers are careful to say this ruler is for helping students learn, not for catching cheaters. It's a tool to spot who needs extra coaching on how to be a smart user of AI, rather than a tool to punish them. By understanding these different "reliance types," schools can teach students to be the master architects of their own writing, using the robot as a helpful assistant rather than a replacement for their own brains.
In short, the study built a new, more accurate map of the AI landscape. It shows us that while the robot is everywhere, the way students walk through that world varies wildly—and now, we finally have a compass to help them find the best path.
