Precautionary Behaviors and Side Effects after Radioiodine for Thyroid Disease: A Prospective Cohort Study
Authors' conclusion
Patients receiving radioiodine have poor recall and may under-adhere to required postdose precautions while adopting unnecessary self-imposed precautions. Patients with maladaptive beliefs before treatment appear to find radioiodine more burdensome and intrusive during the first 4 weeks after treatment.
