Text Messaging Intervention on Happy Family Meal for Improving Family Communication and Well-being in Hong Kong Adults

Family meals are crucial for family communication and well-being. This text messaging intervention digitalizes Happy Family Kitchen II, a face-to-face community-based intervention previously shown to be effective. This is a two-arm, parallel-group, randomized controlled trial (RCT) designed to evaluate the effectiveness of a text messaging intervention aimed at promoting happy family meals among Hong Kong adults. Eligible participants are Hong Kong residents aged 18 or older, with at least one parent or child also aged 18 or older, who can read Chinese and have access to Short Message Service (SMS) and Multimedia Messaging Service (MMS) platforms. A target of approximately 1,050 participants will be stratified by four types of family roles and negative emotional eating status and randomized to either the intervention group, receiving a digital booklet, text messages for two weeks, and two family-based activity boosters, or the waitlist control group. The content is based on five positive psychology themes: joy, gratitude, flow, savoring, and listening. Primary outcomes include improvement in family communication and well-being at three months post-intervention. This study aims to assess the effectiveness of a digital intervention on family communication and well-being through the promotion of happy family meals. By leveraging information communication technologies (ICTs), this intervention offers a scalable and cost-effective approach, providing insights into the feasibility and effectiveness of digitizing community-based interventions.
