N2 - Excessive sugar intake poses a significant risk factor for non-communicable diseases. A positive healthy eating (PHE) intervention was developed to promote low-sugar dietary practices in families. The PHE intervention capitalized on positive psychological constructs to overcome barriers to health behavior change by helping families associate feelings of joy, gratitude, and savoring with healthy eating. In a cluster randomized controlled trial, 1983 participants from 1467 families were recruited in Hong Kong. PHE included a core and booster session. Data were collected at pre-intervention, post-intervention, and at 1-month and 3-month follow-up. Compared to the control, PHE showed greater increase in intention to change at post-intervention, engagement in low-sugar dietary practices individually and with family members at 3-month follow-up, and greater reduction in sugar-sweetened beverage intake at 1-month and 3-month follow-up. Intentions to change mediated PHE’s effects on low-sugar dietary practices. Focus group interviews revealed the behavior-change process and family quality of life.
