Interventions

  • Intervention Video — BEHAVIORAL
    Participants will view a brief prerecorded video (approximately 4 minutes) online, delivered through Qualtrics, following completion of the baseline questionnaire. The intervention video will present information on radioiodine treatment recovery, managing treatment side effects, and radiation safety requirements. The video will be delivered online prior to the participant's radioiodine treatment, using patient-friendly language and supportive framing.
  • Control Video — BEHAVIORAL
    Participants will view a brief prerecorded neutral video (approximately 4 minutes) online, being delivered through Qualtrics following the baseline questionnaire. The control video will present general health information unrelated to radioiodine treatment (e.g., healthy lifestyle topics such as nutrition and stress management). The video will be delivered online prior to the participant's radioiodine treatment, and will match the intervention video in duration, format, and presenter.

Study Details

This study will test the impact of a short video intervention for people who are receiving radioiodine treatment for thyroid conditions (such as hyperthyroidism or thyroid cancer). After their single-dose treatment, patients need to follow safety instructions to protect others and manage side effects during recovery. Some people find these instructions hard to remember, and side effects (or anticipation of side effects) can feel worrying or disruptive. The video aims to present the treatment information in a more accessible patient-friendly way, so that patients feel less distressed, find their side effects easier to cope with, and better engage with safety precautions. All patients will first have a pre-treatment consultation with their doctor and receive the standard treatment information currently provided. Before this consultation patients will be randomly assigned to view one of two videos. The control group will see a neutral video that details standard health information that is not specific to radioiodine, while the intervention group will see a video that explains side effects, safety requirements and recovery period in a more adaptive way. Comparing these two groups will allow us to assess whether this new approach improves coping, reduces distress, and enhances adherence to safety instructions in the post-dose recovery phase of radioiodine treatment.

Arms

  • Experimental: Intervention Video
    Participants assigned to the intervention group will view a brief video that explains radioiodine treatment, side effects, and radiation safety requirements using adaptive and supportive framing.
  • Active Comparator: Control Video
    Participants assigned to the control group will view a neutral video containing general health-related information unrelated to radioiodine treatment. The video will be similar in length, style, and presenter to the intervention video.

Primary Outcome Measure

Post-treatment functional Interference [ Time Frame: From treatment to post-treatment questionnaire (on the last day of radiation safety requirements; approximately 5-7 days post-dose) and at 4-week follow-up. ]
