A cluster randomized controlled trial of a brief positive healthy eating intervention.

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.

A cluster randomized controlled trial of a positive physical activity intervention.

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.

An Evaluation of a Train-the-Trainer Workshop for Social Service Workers to Develop Community-Based Family Interventions.

INTRODUCTION: Evaluation studies on train-the-trainer workshops (TTTs) to develop family well-being interventions are limited in the literature. The Logic Model offers a framework to place some important concepts and tools of intervention science in the hands of frontline service providers. This paper reports on the evaluation of a TTT for a large community-based program to enhance family well-being in Hong Kong. METHODS: The 2-day TTT introduced positive psychology themes (relevant to the programs that the trainees would deliver) and the Logic Model (which provides a framework to guide intervention development and evaluation) for social service workers to guide their community-based family interventions. The effectiveness of the TTT was examined by self-administered questionnaires that assessed trainees' changes in learning (perceived knowledge, self-efficacy, attitude, and intention), trainees' reactions to training content, knowledge sharing, and benefits to their service organizations before and after the training and then 6 months and 1 year later. Missing data were replaced by baseline values in an intention-to-treat analysis. Focus group interviews were conducted approximately 6 months after training. RESULTS: Fifty-six trainees (79% women) joined the TTT. Forty-four and 31 trainees completed the 6-month and 1-year questionnaires, respectively. The trainees indicated that the workshop was informative and well organized. The TTT-enhanced trainees' perceived knowledge, self-efficacy, and attitudes toward the application of the Logic Model and positive psychology constructs in program design. These changes were present with small to large effect size that persisted to the 1 year follow-up. The skills learned were used to develop 31 family interventions that were delivered to about 1,000 families. Qualitative feedback supported the quantitative results. CONCLUSION: This TTT offers a practical example of academic-community partnerships that promote capacity among community social service workers. Goals included sharing basic tools of intervention development and evaluation, and the TTT offered, therefore, the potential of learning skills that extended beyond the lifetime of a single program. CLINICAL TRIAL REGISTRATION: The research protocol was registered at the National Institutes of Health (identifier number: NCT01796275).

Happy Family Kitchen: A community-based research for enhancing family communication and well-being in Hong Kong.

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

Happy Family Kitchen II: a cluster randomized controlled trial of a community-based positive psychology family intervention for subjective happiness and health-related quality of life in Hong Kong.

BACKGROUND: Most positive psychology interventions conducted in the West have been focused on the individual. Family relationships are highly valued in the Chinese collectivist culture, and it is of interest to know whether family-focused interventions can improve the well-being of Chinese people. We have previously reported the effectiveness of a positive psychology family intervention in terms of family well-being. Based on the data derived from the Happy Family Kitchen II project, this paper examines the effectiveness of a community-based positive psychology family intervention on subjective happiness and health-related quality of life. METHODS: Thirty-one social service units and schools organized intervention programs for 2070 participants in Hong Kong. In a cluster randomized controlled trial, participants were randomly assigned on the basis of computer-generated numbers into the intervention group or the control group. The intervention programs emphasized one of five positive psychology themes: joy, gratitude, flow, savoring, and listening. The control group engaged in activities unrelated to the intervention, such as arts and crafts workshops. Subjective happiness and mental and physical quality of life were assessed at baseline and at 4 weeks and 12 weeks postintervention. RESULTS: Data of 1261 participants were analyzed. The results showed that the intervention was more effective than the control condition in improving subjective happiness, with a small effect size, at 12 weeks postintervention (ß = .15, p = .020, Cohen's d = .16). However, there were no improvements in mental and physical quality of life in the intervention group compared with the control group at 4 weeks (ß = .39, p = .494, d = .05; ß = -.10, p = 1.000, d = -.01, respectively) and 12 weeks postintervention (ß = .71, p = .233, d = .08; ß = -.05, p = 1.000, d = -.01, respectively). Furthermore, the booster session was no more effective than the tea gathering session in improving subjective happiness (ß = .00, p = .990, d = .00) or mental (ß = 1.20, p = 1.000, d = -.04) and physical quality of life (ß = .15, p = 1.000, d = -.01). CONCLUSIONS: The analyses extend previous findings of salutary effects on family well-being by showing that positive psychology family interventions can improve subjective happiness. Suggestions for future research are proposed. TRIAL REGISTRATION: ClinicalTrials.gov NCT01796275 . Retrospectively registered 19 February 2013.

Happy Family Kitchen II: A Cluster Randomized Controlled Trial of a Community-Based Family Intervention for Enhancing Family Communication and Well-being in Hong Kong.

Long working hours and stressful urban lifestyles pose major challenges to family communication and well-being in Hong Kong. A community-based family intervention derived from a positive psychology framework, by using cooking and dining as a platform, was developed for improving family communication and well-being. Social workers and teachers from 31 social service units and schools in collaboration with an academic partner organized and conducted the intervention programs for 2,070 individuals from 973 families in a deprived district in Hong Kong. The participants were randomly assigned into the intervention or control group in a cluster randomized controlled trial (cRCT). The core intervention covered one of five positive psychology themes: joy, gratitude, flow, savoring, and listening. Assessments at pre-intervention, immediate post-intervention, and 4 and 12 weeks post-intervention showed improved family communication and well-being with sustainable effects up to 12 weeks. Positive changes in family happiness and family health were greater in the intervention group than in the control group. The savoring intervention had the most improved outcomes among the five themes. We concluded that this large-scale brief cRCT developed and conducted in real-world settings provided evidence for the feasibility and effectiveness of a community-based family intervention. This study was registered under ClinicalTrials.gov (NCT01796275).

Development and Two-Year Follow-Up Evaluation of a Training Workshop for the Large Preventive Positive Psychology Happy Family Kitchen Project in Hong Kong.

Evidence-based practice and capacity-building approaches are essential for large-scale health promotion interventions. However, there are few models in the literature to guide and evaluate training of social service workers in community settings. This paper presents the development and evaluation of the "train-the-trainer" workshop (TTT) for the first large scale, community-based, family intervention projects, entitled "Happy Family Kitchen Project" (HFK) under the FAMILY project, a Hong Kong Jockey Club Initiative for a Harmonious Society. The workshop aimed to enhance social workers' competence and performance in applying positive psychology constructs in their family interventions under HFK to improve family well-being of the community they served. The two-day TTT was developed and implemented by a multidisciplinary team in partnership with community agencies to 50 social workers (64% women). It focused on the enhancement of knowledge, attitude, and practice of five specific positive psychology themes, which were the basis for the subsequent development of the 23 family interventions for 1419 participants. Acceptability and applicability were enhanced by completing a needs assessment prior to the training. The TTT was evaluated by trainees' reactions to the training content and design, changes in learners (trainees) and benefits to the service organizations. Focus group interviews to evaluate the workshop at three months after the training, and questionnaire survey at pre-training, immediately after, six months, one year and two years after training were conducted. There were statistically significant increases with large to moderate effect size in perceived knowledge, self-efficacy and practice after training, which sustained to 2-year follow-up. Furthermore, there were statistically significant improvements in family communication and well-being of the participants in the HFK interventions they implemented after training. This paper offers a practical example of development, implementation and model-based evaluation of training programs, which may be helpful to others seeking to develop such programs in diverse communities.

Three-year outcome of phase-specific early intervention for first-episode psychosis: a cohort study in Hong Kong.

AIM: Although phase-specific early intervention for first-episode psychosis has been implemented in many different parts of the world, limited medium-term outcome data are available in non-Western populations with relatively low mental health resources. The study aimed to determine the effectiveness of phase-specific early intervention in first-episode psychosis. METHOD: In this cohort study, we compared the 3-year outcome of 700 first-episode psychosis patients who received phase-specific early intervention with that of 700 patients matched for age, sex and diagnosis who received standard psychiatric care prior to early intervention. Using a structured data acquisition procedure, we determined functional outcome, symptom levels, relapse, recovery, suicidal behaviour and service utilization from clinical records. RESULTS: Patients in the early intervention group had longer full-time employment or study (P<0.001), fewer days of hospitalization (P<0.001), less severe positive symptoms (P=0.006), less severe negative symptoms (P =0.001), fewer suicides (P=0.009) and fewer disengagements (P=0.002) than the historical control group. Additionally, more patients in the early intervention group experienced a period of recovery (P=0.001), but the two groups had similar rates of relapse (P=0.08) and durations of untreated psychosis (P=0.72). CONCLUSIONS: The 3-year outcome in phase-specific early intervention compared favourably with that of standard psychiatric care, particularly with respect to functional outcome and reduction in hospitalizations, suicides and disengagements. However, intervention did not appear to reduce the rate of relapse.
