简要总结
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.
详细描述
This study is a two-arm randomised controlled trial. Prior to treatment, participants will be randomly assigned to one of two arms. The control group will view a neutral video that discusses general health advice unrelated to the radioiodine treatment, while the intervention group will view a video that reframes side effects and safety instructions in a more adaptive way. All participants will receive a standard pre-treatment consultation with their doctor and the usual written information. Outcomes will then be compared between the two groups in terms of side effects, disability and understanding of treatment precautions. To control for expectation effects both groups will be told that we are testing different videos to assist patients with the radioiodine treatment. This study aims to find out whether a short video intervention (1) helps patients cope better with side effects and get back to normal activities more quickly, (2) improves how well patients remember and understand the safety instructions they need to follow after their dose, (3) reduces disability related to the treatment and its side effects. By examining whether a brief video intervention improves coping with side effects, understanding of safety instructions, and post-treatment recovery, the research will provide new knowledge on how information about radioiodine can be delivered more effectively.

研究组 & 干预措施
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.
干预措施: Intervention Video (Behavioral)
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.
干预措施: Control Video (Behavioral)
结局指标
主要结局
Post-treatment functional Interference
时间窗: 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.
Patient-reported functional interference following radioiodine treatment, assessed using a Functional Interference Questionnaire adapted from standard symptom interference measures. Participants rate the extent to which treatment-related effects interfere with daily activities including work, household tasks, and social participation. Each item is rated on a numeric rating scale from 0 to 10, where 0 = No interference, and 10 = Complete interference (i.e., higher scores indicate worse functioning or greater interference). A mean functional interference score will be calculated across items.
Symptom Attribution to Treatment
时间窗: Pre-dose (1-3 weeks prior to treatment), post-dose (approximately 5-7 days post-dose), and 4-week follow-up.
Symptom attribution assessed using the Side Effect Attribution Scale (SEAS), which measures the extent to which participants attribute experienced symptoms to radioiodine treatment rather than to other causes. Participants rate attribution for 52 symptoms using a a 5-point Likert scale (i.e., 1-5 range): 1. = Definitely not a side effect 2. = Probably not a side effect 3. = Unsure 4. = Probably a side effect 5. = Definitely a side effect Higher scores indicate greater attribution of symptoms to treatment, whilst scores near 3 indicate uncertainty. A total attribution score is calculated by averaging responses across all symptoms.
Adherence to Radiation Safety Precautionary Behaviours
时间窗: 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.
Self-reported adherence to recommended radioiodine radiation safety precautionary behaviours (e.g., distancing, hygiene practices), assessed using a structured adherence questionnaire developed for this study. Adherence is quantified as a composite adherence score, calculated as the proportion of prescribed precautionary behaviours adhered to, with values ranging from 0 to 100%, where higher scores indicate greater adherence.
