Effects of Instituting a Brief Educational Video and a Short Quiz in the Context of a School Screening Program for Scoliosis
Keywords:scoliosis, adolescent, health education, prevalence
Objectives: To evaluate the effects of administering an educational program about scoliosis and spinal health during a scoliosis school screening. To study prevalence of scoliosis in Thai pupils aged 11-18 years.
Study design: Cross-sectional study.
Setting: Rajavinit Mathayom School, Bangkok, Thailand.
Subjects: Thai pupils aged 11-18 years.
Methods: The data from a scoliosis school screening conducted at a secondary school in Bangkok were retrospectively analyzed. All pupils were asked to complete a 10-True/False quiz about spinal health and watch an educational video about scoliosis. Thereafter they were examined with Adam’s forward bending test. A scoliometer was used to measure trunk asymmetry. The pupils with angles of trunk rotation (ATR) greater than or equal to 10º were classified as having scoliosis. Those with ATR between 7º to 9º were classified as at risk and follow up examinations were scheduled for this group. Pupils with ATR less than 7º were classified as normal and required no further re-examination. Then after the back examination, the same quiz was administered a second time in order to assess whether pupils’ knowledge has improved.
Results: An average of 69.6% and 84.4% of the questions were answered correctly at the pre and the post tests. The 14.8% increase in the pupils’ correct answers after watching the video attains a statistical significance at p < 0.001. The three questions that most participants answered incorrectly were about basic pathophysiology, health impact and proper treatments of scoliosis. The prevalence of adolescent idiopathic scoliosis of 2,042 Thai pupils aged 11-18 years was 0.59%. The female to male ratio was 1.1:1.
Conclusion: A brief educational video combined with a short pre- and post-quiz can significantly improve pupils’ essential knowledge about idiopathic scoliosis. When screening with the Adam’s forward bend test and measuring an angle of trunk rotation with a scoliometer, the prevalence of adolescent idiopathic scoliosis in Thai pupils aged 11-18 years was 0.59%.
