Is the definition of 'user' in user studies limited to current users, or does it encompass a broader range of individuals?

For information user studies, the term "user" is often broadly defined to include not only those who currently use a system, service, or information resource, but also potential users, former users, and non-users. Studying non-users is crucial for understanding barriers to access, unmet needs, and opportunities for service improvement or expansion.

Therefore, the statement is true.

The final answer is $\text{True}$
