About this trial
This randomized controlled trial evaluates whether exposure to a medical television drama improves knowledge of neurocysticercosis (NCC) among young adults. Sixty participants aged 18-35 will be randomly assigned to either an intervention group, which will watch a medically relevant TV episode (House M.D., Season 1, Episode 1), or a control group with no media exposure. Both groups will complete pre- and post-test questionnaires assessing knowledge of NCC. The primary outcome is change in NCC-related knowledge. Secondary outcomes include motivation to seek further health information and perceived credibility of the media source

Treatments tested in this trial
Medical TV Drama Episode (House M.D.)
BehavioralParticipants in the experimental group will watch a selected episode of the medical drama House M.D. (Season 1, Episode 1), which includes a dramatized storyline relevant to neurocysticercosis. The episode is intended to deliver narrative-based health education. After viewing, participants will complete post-test questionnaires assessing changes in knowledge, motivation, and credibility compared to pre-test results.
Treatment groups
60 Participants
are divided into 2 treatment groupsGroup A: Intervention (House M.D. Episode)Experimental treatment 1 intervention
Group B: Control (No Episode)No intervention 0 interventions
Trial outcomes
Primary outcomes
1
Change in Neurocysticercosis (NCC) Knowledge Score
Knowledge of neurocysticercosis (NCC) will be assessed using the Neurocysticercosis Knowledge Questionnaire, a 10-item multiple-choice instrument developed for this study. Each correct answer is scored as 1 point, and each incorrect or "I don't know" response is scored as 0 points. The total score represents the sum of correct answers, with a minimum possible score of 0 and a maximum possible score of 10. Higher scores indicate better knowledge of NCC across domains such as cause, transmission, symptoms, prevention, and treatment. The primary outcome is the change in total knowledge score from baseline (pre-test) to immediately post-intervention, compared between the intervention and control groups

Retention of Neurocysticercosis Knowledge
Knowledge retention will be assessed using the Neurocysticercosis Knowledge Questionnaire, the same 10-item multiple-choice instrument used at baseline and immediately post-intervention. Each correct answer is scored as 1 point, and incorrect or "I don't know" responses are scored as 0 points. The total score is the sum of correct responses, with a minimum possible score of 0 and a maximum possible score of 10. Higher scores indicate better retention of NCC knowledge. The outcome measure is the change in total knowledge score from baseline (pre-test) to 4 weeks post-intervention, as well as between-group differences in retained knowledge over time.
Time frame
4 weeks post-intervention.2
Perceived Credibility of the Medical TV Drama
Perceived credibility of the medical TV drama as a health information source will be measured using the Perceived Credibility of Health Media Scale, a 5-item Likert-type scale adapted for this study. Each item is rated from 1 ("Strongly Disagree") to 5 ("Strongly Agree"), assessing dimensions such as trustworthiness, accuracy, and believability of the episode's medical content. Scores for all items will be summed to produce a total credibility score, with a minimum possible score of 5 and a maximum possible score of 25. Higher scores indicate greater perceived credibility and trust in the medical TV drama as a reliable health education resource. The outcome measure is the mean total credibility score immediately following the intervention, compared between the intervention and control groups.
Time frame
Immediately post-intervention (within 1 hour).3
Motivation to Seek Further Health Information
Participants' motivation to seek additional information about neurocysticercosis (NCC) will be assessed using the Motivation to Seek Health Information Scale, a single-item 5-point Likert-type measure adapted for this study. Participants will rate their likelihood of looking for more information about NCC following the intervention, with response options ranging from 1 ("Not at all likely") to 5 ("Extremely likely"). Scores range from 1 to 5, where higher scores indicate greater motivation to seek additional health information. The outcome will be reported as the mean motivation score immediately post-intervention and compared between the intervention and control groups.
Time frame
