15 Intervention

i Types of intervention

Behavior

Please specify

ii Description/ name of Intervention/article

The main caregiver(s) of the subjects will have to attend three educational workshop sessions delivered by the principal investigator over consecutive weeks (week 1-3). General principles on functions and importance of sleep, factors that influence preschooler children’s sleep and ways to help extend sleep duration will be discussed. Each workshop presentation will last for around 40 minutes and then time will be allocated for group discussion and design of individual management strategy for each family. For each workshop session, we will limit the number of families to a maximum of 10 to allow for more in-depth discussion between family members and the investigator. Weekly (week 1-7) telephone interview will be conducted by research personnel to answer queries, provide support and reinforce strategies decided for that particular family, followed by a 6-week (week 8-13) maintenance period.
