Summary

This study looked at how parents cope when their child has a medical condition that doctors haven't been able to diagnose for at least two years. Researchers surveyed 168 parents to understand how uncertainty affects their ability to cope and how personality traits like optimism play a role. The goal was to learn more about the parents' experience, not to test a treatment.
