Objective: Due to global urbanization, technological advancements, and increasing convenience in daily activities, reduced energy expenditure in all aspects of life has become a major public health concern. A positive physical activity (PPA) intervention was developed to promote physical activity and fitness among Hong Kong families. PPA utilizes positive affective attitudes to circumvent barriers to health behavior change by helping families associate feelings of enjoyment with physical activity. Zero-Time Exercise (ZTEx) was introduced and promoted as a foot-in-the-door approach. Method: Using a community-based collaborative approach, the research team worked with social service organizations, a government department, and schools to implement a cluster randomized controlled crossover trial at a citywide scale. A total of 1,983 eligible participants from 1,467 families were recruited from all 18 districts in Hong Kong. Data were collected using structured questionnaires and physical fitness assessments at preintervention and 1-month and 3-month follow-up. Results: PPA was effective in increasing ZTEx and ZTEx with family members at 1-month and 3-month follow-up and in improving balance and endurance at 3-month follow-up. Semistructured focus groups provided further support for the intervention effectiveness and added in-depth insights into the participants' motivational, interpersonal, and affective experiences. Conclusion: The results not only shed light on the intervention's effectiveness for physical activity and fitness but also demonstrated that the community-based collaborative approach was successful in engaging relevant stakeholders in an active and fruitful partnership with effective capacity building for program development.

Our cluster randomized controlled trial tested, respectively, 2 brief interventions to promote more appreciation and less criticism in Hong Kong Chinese parents toward their children and to enhance family well-being. We randomized 56 primary schools and community service centers (clusters of parents of primary grades 3-6 students) to the more appreciation (MA) or less criticism (LC) intervention arms, or fruit and vegetable control arm (FV). A total of 803 parents received a 2-hr workshop on increasing appreciation (19 clusters, n = 270), reducing criticism (21 clusters, n = 336), or increasing fruit and vegetable consumption (16 clusters, n = 197) and were assessed at baseline, immediately after the workshop, at 2 weeks, and at 6 weeks. Primary outcomes were parents' frequency of appreciation and criticism behaviors. Secondary outcomes were family well-being and potential behavioral determinants proposed by the Health Action Process Approach, including outcome expectancies, self-efficacy, intention, and planning behavior. At 6 weeks, the MA and LC arms reported greater increases in appreciation behavior than the FV arm, and the LC arm reported greater decreases in criticism than the FV arm, with small effect sizes. Specific improvements were also observed in the behavioral determinants at various time points compared with the FV arm. Similar improvements in family well-being were observed across all arms. Our findings were the first to show that brief Health Action Process Approach-based workshops on Chinese parents were effective in promoting positive parental behaviors.

Urban families worldwide are often characterized by busy working lives which leave little time for family gatherings and communication. The Happy Family Kitchen project, which emphasized cooking and dining with family members, was conducted in a deprived district in Hong Kong. We hypothesized that the community-based family intervention, derived from a positive psychology framework, can improve family communication, family well-being, and subjective happiness. Twenty-three social service units organized and delivered the intervention programs for 1,419 individuals from 612 families. The core intervention was developed with emphasis on 1 of 5 positive psychology themes: gratitude, flow, happiness, health, and savoring. Intervention outcomes were assessed at preintervention, immediate postintervention, and 6 weeks and 12 weeks postintervention. Results showed that family communication, family well-being, and subjective happiness improved with small effect sizes which were sustained up to 12 weeks. The gratitude intervention improved all of the outcome measures. Qualitative data provided additional evidence for effectiveness with in-depth insights into family dynamics. We concluded that this brief intervention was a low-cost and simple approach to improve family communication and well-being. (PsycINFO Database Record [ABSTRACT FROM AUTHOR]
