Introduction: Dyslexia, which is a learning disability that affects many aspects of children's development, has a prevalence of 5-17%, worldwide. There are many negative perceptions towards children with dyslexia, and one of it is when there is lack of teachers' knowledge about this problem. Aim: The objective of this study is to develop and discuss on a newly developed module on dyslexia, i.e. Dyslexia Health Education Module (DHEM) for preschool teachers, Method: This module is developed using the ADDIE model (A-Analysis, D-De-sign, D-Develop, I-Implement, E-Evaluate). The content of DHEM consists of general information for pre-school teachers about dyslexia, identification and intervention for dyslexia among children as well as its mental health implications. Results: The newly developed module was found to have a good content validity with a score of 0.7 when evaluated by eight expert panels from respective fields. The Cronbach alpha's value for reliability test was 0.90. These findings suggest that this module is good, reliable and applicable. Discussion: It is hoped that with the development of DHEM, this would increase teachers' knowledge on dyslexia among children in Malaysia, especially in recognizing at-risk children and consequently may lead to early intervention in managing the problem. This study also suggests that future longitudinal studies should be carried out using this module to ensure its effectiveness in the long run. � 2020 UPM Press. All rights reserved.

Posttraumatic stress disorder (PTSD) is a psychiatric diagnosis made when someone including children who experiences traumatic stressor. Those who are exposed to a more severe trauma have highest level of PTSD. The aim of this study was to measure the prevalence of PTSD and its associated factors among 219 children who were affected by a form of natural disaster which is the tsunami waves in a rural area in Malaysia. A cross sectional study was carried out among children aged 10-12 years 6 months after the traumatic event. Child Posttraumatic Stress Disorder -Reaction Index (CPTSD-RI) was used as a screening instrument which was answered by the affected children through a self-administered questionnaire. Forty six percent of these children had PTSD symptoms; 31.1% of these children had mild, 11.4% had moderate, 3.7% had severe PTSD and none had very severe PTSD. Result also showed that 91.8% had re-experiencing symptoms, 28.3% had numbing/avoidance symptoms and 49.3% had hyperarousal symptoms. Children with low social support (Adj OR = 2.3 (95% CI: = 1.3- 4.2)), and children who experienced deaths among someone close to them (Adj OR = 3.7 (95% CI =1.2 - 11.5)) were more likely to have symptoms of PTSD. This showed that children are at higher risk of developing PTSD as early as 6 months after the event and thus early intervention should be offered to them. Future longitudinal study can be carried out among affected children to assess whether these PTSD symptoms persist over time.
