During an initial evaluation, if a participant refuses to keep their helmet on for an extended period, what should the instructor do next?

The correct choice is effective because it addresses the participant's discomfort with wearing the helmet by helping them acclimate to the sensation gradually. By suggesting that the participant wear a snug hat during the day, the instructor is introducing a less intimidating way for the individual to adapt to the pressure and fit of a helmet. This approach can mitigate anxiety and serve as a preparatory step towards eventually wearing the helmet comfortably.

Building tolerance for headgear is important in therapeutic riding, as safety is paramount, and consistent helmet use is a key requirement. The gradual adaptation can lead to greater acceptance of the helmet and a more successful riding experience.

Other options, while they may have some merit, do not strategically address the underlying issue of acclimatization to the helmet itself. Wearing a hoodie could potentially introduce complications with fitting or safety, and anticipating that the participant will wear the helmet without addressing their concerns is unlikely to be effective. Recommending local therapists does not directly tackle the immediate issue of helmet discomfort and could separate the participant from the immediate context of the riding environment.
