Generalizability, or external validity, hinges on whether study findings would apply to people, settings, and practices beyond the exact conditions of the study. In art therapy, this means looking at who was studied (population characteristics such as demographics, diagnoses, presenting issues), where the therapy took place (settings like schools, clinics, or community centers), and how the therapy was delivered (the specific intervention used, its duration, frequency, materials, and the therapist’s training or supervision). It also involves noting any limitations the researchers identify about applying the results to real-world practice—things like sample diversity, treatment fidelity, and whether outcome measures match what clinicians would use at work. When these elements align with real-world contexts, the study’s findings are more likely to generalize beyond the sample.

The other options don’t address how widely the results would apply: journal impact factor speaks to perceived prestige, not transferability; the number of pages provides little about generalizability; abstract length doesn’t determine applicability to practice.
