Background Road traffic accidents is the second most common cause of death among Thai children after drowning. There is very little use of child restraint in car in Thailand. Therefore, we were established the promotion of child restraint use among Thai family during postpartum period.

Objectives To explore attitudes,normative beliefs and intention for child restraint used in Thai family

Methods This qualitative study was conducted during November 2014 to April 2015 at Khon Kaen Hospital. The volunteers are 30 Thai parents of postpartum with healthy infant who received healthcare information and use their cars on a daily basis. The process of implementation consists of the practical training in the use of child restraint to volunteer after birth and group meeting every 2 months. Interviewing data were collected at 6 months after training to identify attitudes normative beliefs and intention to use child restraint

Results 90% of participating parents used the child restraint continuously and correctly. The reasons for using the child restraint were: confidence that their children will be safer than carrying their children on their lap in the car,having more concentration to drive the car, muchmore comfort when the mothers have to drive the car alone. While the intermittent a child restraint used groups, their comments were inappropriate to use child restraint due to the children were hot, crying and refusing, travelling at long distance, no child -parents bonding by the separated car seat, influence on decision by the old age people in families who believed that holding baby by parent were safer than using child restraint. the number of peoples in their families and the size of their car , but soon they found technique to solve the problems and shared the technique among the group.Next steps,we are going to advocate for child restraint legislation, intensive public relation to raise more social awareness for safety of the children in the car.

Conclusions Participation of knowledge exchange in child restraint use in the car among participants can lead to improve and support good cognitive behaviour in the subgroup. However supporting the devices with low price, strong public relation, education program for mothers at ANC and well baby clinics and legislation are important factors that influence behavioural change.
