Effectiveness of an Audiovisual Disaster-Education Intervention on Disaster Risk Perception and Preparedness Belief Among Senior High-School Adolescents
Sponsor: Tanjungpura University
Summary
This cluster-randomized controlled trial tests whether a short, standardized disaster-education video improves two psychological precursors of disaster preparedness among senior high-school students in a hazard-prone district of West Kalimantan, Indonesia. Twelve intact classes at one senior high school will be randomized 1:1, stratified by grade level, either to view a purpose-built audiovisual disaster-education module (approximately 20 minutes, shown twice in a single classroom session) or to view an attention-matched general adolescent-health video of similar length on an unrelated topic. Randomization is at the class level to reduce contamination between students, and the individual student is the unit of analysis. All students in a participating class view the video allocated to that class; a randomly drawn subsample of twelve students per class, 144 in total, completes the study questionnaires. Two co-primary outcomes are measured in every participant. The first is disaster preparedness belief, measured by the General Disaster Preparedness Belief (GDPB) scale. The second is disaster risk perception, measured by the Disaster Risk Perception Scale (DRPS). Both are collected at baseline before allocation, immediately after the session, and again four weeks later. The intervention and both instruments are grounded in the Health Belief Model, which predicts that raising perceived threat contributes to readiness to act. An exploratory mediation analysis will test whether change in risk perception explains part of any effect on preparedness belief. After the four-week assessment, control classes are offered the full disaster-education intervention.

Conditions
Interventions
Audiovisual disaster-education module
A purpose-built educational video on disaster preparedness, approximately 20 minutes in duration, developed through a structured instructional-design cycle (needs analysis, learning objectives, storyboard, production, expert content validation withitem-level content validity index \[I-CVI\] of at least 0.78 and scale-level content validity index, average method \[S-CVI/Ave\], of at least 0.90, comprehension pilot, and lock). The defined dose is one viewing repeated twice in the same session, identical for every intervention cluster. An optional fully scripted five-minute debrief may follow. No deviation from this dose is permitted without a documented protocol amendment.
Attention-matched general-health video
A general adolescent-health video on a topic unrelated to disaster preparedness (for example, personal hygiene or balanced nutrition), matched to the experimental module for duration, delivery format, room conditions, and facilitator contact time.
