Attitudes Toward Obstructive Sleep Apnea-Related Cause of Road Traffic Accidents in Thailand Through Well Prepared Educational Video

Participants were asked to complete a set of questionnaires on obstructive sleep apnea and traffic accidents. The questionnaires were the modified version of the International Association of Traffic and Safety Sciences (IATSS) questionnaires. The questionnaires were designed as a self-administered questionnaire to access the attitudes and awareness of the health-related cause of traffic accidents focusing primarily on OSA. The questionnaire set was performed as an online questionnaire using Google Form. The questionnaires and videos were promoted through electronic posters. Participants were able to evaluate the questionnaire using the QR codes or links provided.

The questionnaire set consisted of three parts: 1) pre-test part (questionnaire before video watching), 2) educational video part (consisting of two videos), and 3) post-test part (questionnaire after video watching).

Participants were asked to complete the pre-test questionnaire part, which contained 13 items including 6 items on demographics of participants (gender, age, home town, frequency of motor vehicle use, education level, and occupation), 1 item on the underlying diseases of OSA, 1 item testing basic knowledge about common OSA symptoms, and 5 items regarding attitudes about OSA before watching educational videos.

Upon completion of the pre-test questionnaires and before starting the post-test questionnaires, participants were directed to the educational videos which were embedded in the same google form after the pre-test questionnaire. The purpose of the videos was to provide basic knowledge and to raise awareness of the OSA-related cause of traffic accidents. There were two videos including the first video "Sleep apnea Syndrome Driving Safety Picture Scroll" and the second video "Sleep apnea Syndrome and Traffic Accidents". The first video was approximately 3 minutes long. This video was suitable for all ages. It was an easy-to-understand video explaining the characteristics of OSA and its relationship with traffic accidents. The second video was the detailed video, which is approximately 20 minutes in duration. This video was suitable for those who desire to learn more about OSA. It can be used in various educational settings, including internal training and traffic safety workshops. Participants must watch at least the first video.

After viewing the videos, the participants were directed to the post-test questionnaires in the same google form. The post-test questionnaires contained 22 items including 10 items on attitudes about OSA or glaucoma (containing 5 same items as the pre-test questionnaires) and 12 items on video feedback. In conclusion, this questionnaire set consisted of 33 questions.
