Effectiveness of a Baby App for Enhancing Infant Mental Well-being (RCT)

Study Overview
=================
Brief Summary
-----------------
This RCT aims to design and develop a developmental guidance program delivered by a smartphone app Happy Baby HK and evaluate its effectiveness for enhancing the mental well-being of recently born infants in Hong Kong. This study will evaluate the effectiveness of the improvement in the effect of infants and decrease of risk of developmental delay in very young children. The smartphone app Happy Baby HK will be designed and developed by different professionals. Then, participants will be invited to use this app or the MCHC parenting booklet. They will also be invited to fill in some questionnaires at 6, 12 and 18 months postpartum to screen the developmental stages. Researchers will compare the intervention group and the control group to evaluate the effectiveness of this app for enhancing the mental well-being of infants.

Detailed Description
-----------------
Infant mental health refers to the developing capacity of the child from birth to age three to experience, regulate, and express emotions; form close and secure interpersonal relationships; and explore the environment and learn - all in the context of family, community, and cultural expectations for young children. Despite the stability of temperamental characteristics across context and over time, environmental factors such as good mother-infant relationship can protect against the development of psychiatric morbidities in children with difficult temperament. Research studies also show that anticipatory guidance interventions can promote optimal child development, increase maternal knowledge of their infants, positive parent-infant interactions and reduce injury rates. To enhance infant mental well-being, the proposed project team designs a smartphone app Happy Baby HK that provides development guidance to mothers of recently born infants in Hong Kong. Compared to traditional approaches (e.g. parenting pamphlets or clinical consultation on developmental issues), smartphone apps devoted to parenting guidance could feature video demonstrations, quizzes, interactive games, and written information with vivid images and cartoons which are more likely to engage parents and reinforce their learning anytime and anywhere. However, currently there is no technology-based intervention with provision of anticipatory guidance information on child development in Hong Kong. Therefore, the objective of this study is to design and develop a developmental guidance program delivered by a smartphone app Hapy Baby HK and evaluate its effectiveness for enhancing the mental well-being of recently born infants in Hong Kong. The improvement on parental stress will also be evaluated.
