Throughout the study, researchers studied 48 participants. Half of the participants had body-focused repetitive behaviors, nail biting is considered one. The other half had no repetitive habits such as these.
They performed the study by having every participant fill out a number of surveys, which were made to test their emotion regulations and organizational behavior, to try and figure out why people have these habits.
