Abstract
Objective: To explore the relationship between extracellular enzymes activity and virulence of Candida glabrata clinical isolates based on the infection model of Galleria mellonella larvae. Methods: Using experimental research methods, 71 strains of non-repetitive Candida glabrata were collected from Qinghai Provincial People's Hospital from June 2021 to January 2022. Bovine serum protein agar medium, egg yolk agar medium, sheep blood agar medium, Tween-80 agar medium and triglyceride agar medium were used to detect the aspartyl protease activity, phospholipase activity, hemolysis activity, esterase activity and lipase activity of Candida glabrata. Median lethal concentration (LC50) was calculated by using 1.25×108 CFU/ml,2.50×108 CFU/ml,3.75×108 CFU/ml,5.00×108 CFU/ml suspension of Candida glabrata ATCC2001 to infect Galleria mellonella larvae. Histopathological and etiological analysis was performed to determine whether the infection model was successfully established. The clinical isolates of Candida glabrata were configured to infect Galleria mellonella larvae with LC50 concentration to detect the pathogenicity of Galleria mellonella larvae.Spearman test or Pearson test were used to analyze the correlation between the extracellular enzyme activity of Candida glabrata clinical isolates and the pathogenicity of Galleria mellonella larvae. Results: 71 strains of Candida glabrata isolated clinically were detected to have low hemolytic activity after 2 days of culture. Aspartyl protease was detected after 4 days of culture, among which 7 strains (9.86%), 19 strains (26.76%) and 45 strains (63.38%) showed low, medium and high aspartyl protease activity. After 7 days of culture, 71 strains did not detect phospholipase, esterase and lipase activities. Candida glabrata on Galleria mellonella larvae of LC50=2.5×108 CFU/ml Fungal spore were found in the intestinal tissue pathological section of Galleria mellonella larvae in the experimental group, and Candida glabrata was identified by the microbial Mass Spectrometry after culture, while no fungi were found in the pathological section and culture of the control group. Spearman test shows that, there was a linear positive correlation between aspartyl protease activity and the survival rate of Galleria mellonella larvae (r = 0.73, P<0.01), the difference was statistically significant.Pearson test shows that, there was no significant linear relationship between hemolytic activity and survival rate of Galleria mellonella larvae (r = 0.16, P = 0.34), the difference was not statistically significant. Conclusion: The clinical isolates of Candida glabrata in this study had aspartyl protease activity and low hemolytic activity, but no phospholipase, esterase and lipase activity. The activity of aspartyl aspartyl protease of Candida glabrata was positively correlated with the pathogenicity of Galleria mellonella larvae.

Abstract
Purpose: To evaluate the factor structure and psychometric properties of the 10-item Family Communication Scale (FCS) in the Chinese population. Methods: Study 1 was a population-based survey [N = 687, 61.1% female; mean age (SD) 56.6 (19.1)]. Study 2 was a community-based intervention (N = 1983, 76.7% female; 57.8% aged 20-59 years). We conducted exploratory factor analysis (EFA) in Study 1 and replicated the model by confirmatory factor analysis (CFA) in Study 2. Psychometric properties were evaluated, including internal consistency, test-retest reliability, convergent and discriminant validity, and known-group validity. We identified how the FCS scores differed by sociodemographic characteristics and communication methods including face to face and Information and Communication Technologies (ICTs) in Study 1. Results: The EFA and CFA supported a one-factor structure. The Chinese FCS showed a good internal consistency (Cronbach's alpha = 0.91; McDonald's Omega = 0.91) and was stable over 1-month (intraclass correlation coefficient = 0.69, P < 0.001). Convergent validity was supported by positive correlations of FCS with the Subjective Happiness Scale, Family Adaption, Partnership, Growth, Affection, Resolve (APGAR) Scale, family health, harmony, and happiness, and perceived family communication sufficiency and quality (All P < 0.001). Discriminant validity was supported by the stronger correlation of FCS with Short Form-12 Health Survey Version 2 Mental Component than that with Physical Component (P < 0.001). Higher household income, frequent face-to-face communication, and frequent use of phone calls, instant messaging, and social networking sites were associated with higher FCS scores. Conclusion: The one-factor structure of the Chinese FCS can be a reliable and valid measurement of positive family communication, in the context of ICT integration into family communication.

Abstract
INTRODUCTION Hong Kong has a great diversity of plants, many of which are toxic to humans. The aim of this study was to identify the plant species most commonly involved in cases of plant poisoning in Hong Kong and to provide clinicians with a reference tool for the diagnosis and management of plant poisoning. METHODS We retrospectively reviewed all plant poisoning cases referred to the Hospital Authority Toxicology Reference Laboratory from 1 January 2003 to 31 December 2017. Demographics, clinical presentation, laboratory findings, treatment and outcomes of patients, as well as morphological identification and analytical testing of the plant specimens, were investigated. RESULTS A total of 62 cases involving 26 poisonous plant species were identified, among which Alocasia macrorrhizos (Giant Alocasia), Gelsemium elegans (Graceful Jessamine), and Rhododendron (Azalea) species were the three most commonly encountered. Gastrointestinal toxicity (n=30, 48%), neurological toxicity (n=22, 35%), and hepatotoxicity (n=6, 10%) were the three most common clinical problems. Forty-nine (79%) and eight (13%) patients had mild and moderate toxicity, respectively; they all recovered shortly with supportive treatment. The remaining five (8%) patients experienced severe toxicity requiring intensive care support. Most patients (n=61, 98%) used the plants intentionally: as a medicinal herb (n=31), as food (n=29), and for attempting suicide (n=1). Reasons for using the poisonous plants included misidentification (n=34, 55%), unawareness of the toxicity (n=20, 32%), and contamination (n=6, 10%). CONCLUSIONS Although most plant exposure resulted in a self-limiting disease, severe poisonings were encountered. Epidemiology of plant poisonings is geographically specific. Clinicians should be aware of local poisonous plants and their toxicities.

Abstract
To ease the shortage of professionals, lay volunteers were trained to become health promoters and role models for a large community program to enhance physical activity, well-being, and neighborhood cohesion in socioeconomically disadvantaged groups in Hong Kong. This study aimed to examine the effects on health promoters (trainees) and the feasibility and acceptability of capability-building train-the-trainer workshops (TTTs) using Zero-time Exercise (ZTEx) to implement a community program for about 1,000 participants. A four-session (totally 8 hours) TTT introduced an evidence-based ZTEx intervention to enhance physical activity and well-being, and build capacity for community program implementation. Twenty-eight trainees actively participated in the TTT. Twenty-five and 21 trainees completed the 1- and 3-month questionnaires, respectively. Eleven trainees attended the 1-year focus group interview. Repeated measures analysis of variance and Friedman test were used to compare the parametric and nonparametric data, respectively. Qualitative data were analyzed using thematic content analysis. The trainees reduced their sedentary behavior and improved their interpersonal communication skills, knowledge, and attitude toward ZTEx, grip strength, balance, and perceived well-being. The community participants reported improvements in neighborhood cohesion and grip strength. The 1-year qualitative results supported the 3-month quantitative findings. This brief and innovative TTT affirmed the feasibility of using ZTEx and the role modeling approach for lay health promoters to reduce sedentary behavior and enhance physical activity, fitness, and well-being. They then contributed to the successful implementation of community programs that benefited many. This study provides a new model for building capacity for health promotion in the community.

Abstract
INTRODUCTION Mesh-related complications from reconstructive surgery for pelvic organ prolapse are of international concern. The present study aimed to review the incidence, management, and surgical outcomes of mesh-related complications in a Chinese population compared with existing studies involving Western populations. METHODS This was an analysis of a prospectively collected cohort. Laparoscopic sacrocolpopexy, laparoscopic hystercolposacropexy, or transvaginal mesh surgery were offered with or without concomitant vaginal hysterectomy or continence surgery. Patients were followed up and mesh-related complications were noted. RESULTS Overall, 276 Chinese women who received mesh surgery were included for data analysis. There were 22 mesh-related complications found during a mean follow-up period of 40 months. Mesh exposure accounted for 20 these complications; significantly more occurred after transvaginal than after abdominal mesh surgery (16 vs 4; P=0.01). Median duration from primary operation to the time of mesh exposure detection was 12 months (interquartile range=4.8-32.8 months). Ten patients required surgical excisions of exposed mesh. The re-operation rate after mesh complications was 6.7% (9/134) for transvaginal mesh surgery and 1.4% (2/142) for laparoscopic sacrocolpopexy (P=0.03). All excisions were performed transvaginally and 95% remained well after surgery. Occurrence of mesh exposure was higher in transvaginal mesh surgery (adjusted odds ratio=6.1; P=0.008), in sexually active patients (adjusted odds ratio=5.4; P=0.002), and in obese patients (adjusted odds ratio=3.7; P=0.046). Over 90% were satisfied with the outcome, regardless of mesh complications. CONCLUSIONS The rates of mesh exposure and re-operation were consistent with those reported in the literature, suggesting no significant differences in outcome between Chinese and Western patients for this type of surgery.

Abstract
Aims To compare the efficacy of brief advice about cut-down-to-quit (CDTQ) with that of brief advice about quit immediately (QI), as delivered by trained volunteers, without the use of pharmacological therapy, to outreach-recruited Chinese smokers in Hong Kong who intend to quit smoking. Methods Smokers (N = 1077) who enrolled in the Quit and Win Contest 2014 and intended to quit or reduce smoking were randomized in participation sessions to CDTQ (n = 559) and QI (n = 518) groups. Subjects in the CDTQ group received brief advice and a card about smoking reduction. Subjects in the QI group received brief advice and a leaflet about quitting smoking. All received a smoking cessation booklet and corresponding CDTQ or QI brief telephone advice at intervals of 1 week, 1 month, or 2 months. The primary outcomes were self-reported 7-day point prevalence abstinence (PPA) at the 3-month and 6-month follow-ups. The secondary outcomes included abstinence rate as validated by biochemical tests, smoking reduction (≥50% reduction from baseline), and quit attempt (QA). The outcome assessors were blinded as to group assignment. Results By intention to treat, the QI and CDTQ groups showed similar results as regards (i) self-reported PPA (10.6% [95% CI 8.1%-13.6%] vs. 9.1% [95% CI 6.9%-11.8%]), (ii) validated abstinence rate (5.6% [3.8%-7.9%] vs. 5.4% [3.6%-7.6%]), and (iii) QA rate (59.2% [53.5%-64.8%] vs. 54.1% [48.7%-59.3%]) at 6-month. However, the CDTQ group showed a significantly higher reduction rate than the QI group (20.9% [CI 17.6%-24.5%] vs. 14.5% [11.6%-17.8%]). The overall intervention adherence was suboptimal (45.4%), particularly in the CDTQ group (42.3%). Self-efficacy as regards quitting of smoking was similar between the groups at 6 months. Conclusions Brief advice on CDTQ and QI had similar short-term PPAs. Longer-term follow-up is needed to understand the latent effect of smoking reduction on abstinence. Implications This is the first randomized controlled trial in ethnic Chinese smokers to evaluate the relative efficacy of brief advice on (a) CDTQ and (b) QI as regards quitting. The two interventions showed similar effects as regards PPA. The findings suggested that brief advice on CDTQ may be as effective as brief advice on QI in smokers recruited in community settings.

Abstract
Background Recruitment is central to any research project, and recruitment itself should be well documented and researched. We describe our recruitment efforts for a community-based research project-entitled the Learning Families Project-conducted in Hong Kong. Methods In collaboration with community stakeholders, residents from a public housing estate were recruited to participate in family programs aimed at enhancing family well-being. Various recruitment strategies were employed including the distribution of 19,200 leaflets, 688 posters, a banner, a kick-off ceremony, 10 promotion activities, 1,000 direct calls, word of mouth, 51 mobile counters, and 10 door-to-door visits. Drawing on field notes, research logs, short questionnaires, and focus group conducted with our community partners and residents, we describe and discuss our recruitment strategies, challenges, and lessons learned. Results Over a 9-month period, 980 participants were recruited and participated in our study, exceeding our recruitment goal (860 participants). Several observations were made including active recruitment strategies (i.e., door-to-door and mobile counter) being more effective than passive strategies (i.e., posters and leaflets); the importance of raising project awareness to facilitate recruitment; and the challenges encountered (i.e., burn-out and loss of motivation of staff, decreased community capacity in collaborating in research projects). Conclusion The lessons learned include the importance of engaging Chinese communities, utilizing a positive outreach approach, and setting realistic expectations. Although similar recruitment strategies have been reported the West, a number of cultural differences should be taken into account when working with Chinese population. Further research is needed to examine the effectiveness of tailoring recruitment strategies to various populations.

Abstract
IMPORTANCE Most smoking cessation (SC) clinics are costly, passive, and underused. OBJECTIVE To compare the SC effect of a combined intervention involving brief, model-guided SC advice plus active referral to SC services (active referral group) with those of brief, model-guided SC advice only (brief advice group) and general SC advice only (control group). DESIGN, SETTING, AND PARTICIPANTS A single-blind, 3-arm, pragmatic cluster randomized clinical trial was conducted including 1226 adult daily smokers in the general Hong Kong community proactively recruited to participate in the Quit-to-Win Contest held in 2015. The study was conducted from June 20 to September 24, 2015. Participants were randomly allocated to the active referral (n = 402), brief advice (n = 416), and control (n = 408) groups. Intention-to-treat analysis was used. INTERVENTIONS Brief telephone counseling was offered to the active referral and brief advice groups at 1 and 2 months. Interventions were delivered by SC ambassadors who had undergone a short training period. MAIN OUTCOMES AND MEASURES The primary outcome was the self-reported past 7-day point prevalence of abstinence (PPA) at 6 months. The secondary outcomes were carbon monoxide level-validated abstinence, smoking reduction, and SC service use. RESULTS Participants included 991 (80.8%) men; mean (SD) age was 42.0 (14.8) years. The response rate was 68.2% at 3 and 72.3% at 6 months. The corresponding PPAs were 18.9% and 17.2% in the active referral group-higher than in the brief advice (8.9% and 9.4%; both P ≤ .001) or control (14.0% and 11.5%; P = .03 at 6 months) groups. Compared with the other 2 groups, the active referral group had significantly higher validated abstinence rates (10.2% at 3 months and 9.0% at 6 months, all P < .05) with odds ratios of 2.84 (95% CI, 1.57-5.15) and 2.61 (95% CI, 1.46-4.68) at 3 months, and 1.85 (95% CI, 1.06-3.23) and 1.81 (95% CI, 1.04-3.16) at 6 months in the brief advice and control groups, respectively. The SC service use rate was significantly higher in the active referral group (25.1%) than in either brief advice (2.4%) or control (3.4%) groups at 6 months (P < .001). CONCLUSIONS AND RELEVANCE An intervention involving brief advice and active referral delivered to smokers in the community by volunteers can increase quitting in places where SC services are available but underused.

Abstract
BACKGROUND Neighborhood cohesion, which refers to the extent of the connectedness and solidarity among residents in a community or neighborhood, is an important determinant of human health. To enhance neighborhood cohesion, the "Learning Families Project" was developed with a series of intervention programs in Kwun Tong in Hong Kong, a district with low neighborhood cohesion. This project, based on the social ecological model, provided a platform for neighbors to learn, communicate and interact with each other. METHODS This quasi-experimental study included two nearby government subsidized low rent housing estates separated by busy main roads. One served as the intervention (Tsui Ping (South) Estate) and one as the control (Shun Tin Estate) estate. The intervention included promotion, resident training and learning programs, embodied by a series of community activities such as talks, day camp, thematic activities and horticulture class. Baseline (before the programs) and follow-up (one year after the programs) surveys were conducted both in the intervention and control estate to assess the impact of the programs on neighborhood cohesion. RESULTS The number of residents who completed both the baseline and follow-up surveys was 502 in the intervention estate and 476 in the control estate. Neighborhood cohesion significantly improved in the intervention group after the programs (Cohen effect size d: 0.15). Compared with the control group, the improvements in closeness of the neighborhood and trust in neighbors were significantly greater in the intervention group (Cohen effect size d: 0.13 and 0.14, respectively). CONCLUSION This brief intervention program using a quasi-experimental study design increased neighborhood cohesion in a low rent housing estate. TRIAL REGISTRATION ClinicalTrials.gov NCT02851667.

Abstract
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).

Abstract
Background Community engagement is a powerful tool in bringing about positive social and community change. Community stakeholders possess critical experience and knowledge that are needed to inform the development of community-based projects. However, limited literature is available on the practical experience involved with planning and implementing community-based family programs. Even less has been published documenting efforts in Chinese communities. This paper explores community stakeholders’ experiences with the enhancing family well-being project—part of a citywide project entitled the “FAMILY Project,” aimed at promoting family health, happiness, and harmony in Hong Kong. Methods This qualitative evaluation examined the perspectives of community stakeholders. Four focus groups with social workers (n = 24) and six in-depth interviews with steering committee members were conducted from December 2012 to May 2013 in Hong Kong. Focus groups and in-depths interview were audiotaped, transcribed, and analyzed using thematic analysis techniques. Results Rich accounts were given by our respondents on various aspects of the project. Main themes and subthemes were identified and grouped into four categories (project conception, project implementation, project consolidation, and the overall impact of the project). Respondents described the practical challenges associated with the project (e.g., recruitment, balancing scientific research, and lack of resources) and identified the elements that are important to the success of the project. These included the commitment to a shared goal, multi-agency collaboration, and a platform for knowledge exchange. Finally, respondents perceived benefits of the project at both the individual and community level. Conclusion Our project sheds light on many of the practical considerations and challenges associated with a designing and implementing a community-based family intervention project. Community stakeholders input provided important information on their perceived benefits and barriers and can inform and improve future development of community-based family intervention programs.

Abstract
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
INTRODUCTION To investigate the associations of cigarette smoking and secondhand (SHS) exposure at home with family well-being among Chinese adults in Hong Kong. METHODS Telephone surveys were conducted among 3043 randomly selected adults (response rate 70%) in 2010 and 2012 to monitor family health information and tobacco use in Hong Kong. Family well-being was measured using three questions of perceived family harmony, happiness and health (3Hs) with responses ranging from 0-10 and a higher score indicating better family well-being. Smoking status, nicotine dependence, quitting behaviours and SHS exposure at home were recorded. Multiple linear regressions were used to calculate β-coefficients for individual family 3Hs component and an overall composite score representing family well-being. RESULTS Compared with never smokers, current smokers reported lower levels of family harmony (adjusted β = -0.15, 95% CI: -0.35 to -0.10), happiness (adjusted β = -0.12, 95% CI: -0.28 to -0.02), health (adjusted β = -0.15, 95% CI: -0.30 to -0.03) and overall family well-being (adjusted β = -0.17, 95% CI: -0.32 to -0.06). Quit attempt and intention to quit were not associated with family well-being. SHS exposure at home was associated with lower levels of family harmony (adjusted β = -0.17, 95% CI: -0.30 to -0.07), happiness (adjusted β = -0.19, 95% CI: -0.32 to -0.08), health (adjusted β = -0.13, 95% CI: -0.26 to -0.03) and family well-being (adjusted β = -0.19, 95% CI: -0.32 to -0.09). CONCLUSIONS Smoking and SHS exposure at home were associated with the lower levels of perceived family well-being. Prospective studies are needed to confirm the results.

[PMID: 27473842 PMCID: PMC4966601 DOI: 10.1186/s13063-016-1508-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2016] [Accepted: 07/15/2016] [Indexed: 11/10/2022] Open
Abstract
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 (β = .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 (β = .39, p = .494, d = .05; β = -.10, p = 1.000, d = -.01, respectively) and 12 weeks postintervention (β = .71, p = .233, d = .08; β = -.05, p = 1.000, d = -.01, respectively). Furthermore, the booster session was no more effective than the tea gathering session in improving subjective happiness (β = .00, p = .990, d = .00) or mental (β = 1.20, p = 1.000, d = -.04) and physical quality of life (β = .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.

Abstract
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).

Abstract
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.

Abstract
OBJECTIVE The evidence on the effect of secondhand smoke (SHS) on Health Related Quality of Life (HRQoL) is limited. We examined the relation between SHS and HRQoL among Chinese in Hong Kong. METHODS Adult never smokers from a probability sample of three cross-sectional waves (2010, 2012, 2013) of The Hong Kong Family and Health Information Trends Survey who completed the Cantonese-version of Short-Form 12 Health Survey Questionnaire (SF12v2) were included in the data analysis conducted in 2014. Models were used to examine associations of SHS with SF12 domains and summary scores of Physical (PCS12) and Mental Component (MCS12) with subgroups analysis by SHS locations. RESULTS After adjustments, SHS was associated with lower scores on all SF12 domains except physical functioning. PCS12 (regress coefficient=-0.76, 95% CI -1.34 to -0.17) and MCS12 (regress coefficient=-1.35, 95% CI -2.06 to -0.64) were lower in those with SHS exposure than those non-exposed. Those exposed to SHS in outdoor public places had lower scores on most SF12 domains and PSC12 and MCS12. SHS exposure in one's home and workplace was associated with lower scores on role physical, body pain and role emotional while SHS exposure in friends' homes was additionally associated with lower social functioning and mental health scores. Lower MCS12 was associated with SHS exposure at all locations except one's home. CONCLUSIONS Our study showed that SHS exposure, particularly in outdoor public places, was associated with decreased HRQoL. It can provide new evidence for stronger smoke-free policies on public places and promoting smoke-free homes.

Abstract
Background Family communication is central to the family and its functioning. It is a mutual process in which family members create, share, and regulate meaning. Advancement and proliferation of information and communication technologies (ICTs) continues to change methods of family communication. However, little is known about the use of different methods for family communication and the influence on family well-being. Objective We investigated the sociodemographic factors associated with different methods of family communication and how they are associated with perceived family harmony, happiness, and health (3Hs) among Chinese adults in Hong Kong. Methods Data came from a territory-wide probability-based telephone survey using the Family and Health Information Trend survey (FHInTs). Frequency of family communication using different methods (ie, face-to-face, phone, instant messaging [IM], social media sites, and email) were recoded and classified as frequent (always/sometimes) and nonfrequent (seldom/never) use. Family well-being was measured using 3 questions of perceived family harmony, happiness, and health with higher scores indicating better family well-being. Adjusted odds ratios for family communication methods by sociodemographic characteristics and adjusted beta coefficients for family well-being by communication methods were calculated. Results A total of 1502 adults were surveyed. Face-to-face (94.85%, 1408/1484) was the most frequent means of communication followed by phone (78.08%, 796/1484), IM (53.64%, 796/1484), social media sites (17.60%, 261/1484), and email (13.39%, 198/1484). Younger age was associated with the use of phone, IM, and social media sites for family communication. Higher educational attainment was associated with more frequent use of all modes of communication, whereas higher family income was only significantly associated with more frequent use of IM and email (P=.001). Face-to-face (beta 0.65, 95% CI 0.33-0.97) and phone use (beta 0.20, 95% CI 0.02-0.38) for family communication were associated with significantly higher levels of perceived family well-being. Conclusions Socioeconomic disparities in using these information and communication technologies (ICT) methods for family communication were observed. Although traditional methods remain as the main platform for family communication and were associated with better family well-being, a notable proportion of respondents are using new ICT methods, which were not associated with perceived family well-being. Because ICTs will continue to diversify modes of family communication, more research is needed to understand the impact of ICTs on family communication and well-being.

Abstract
Culture plays a role in mental health, partly by defining the characteristics that are indicative of positive adjustment. In Chinese cultures, positive family relationships are considered central to well-being. The culturally emphasized characteristic of family harmony may be an important factor associated with psychopathology. This article presents the development and psychometric examination of the Family Harmony Scale (FHS), an indigenously developed 24-item instrument tapping family harmony in 17,461 Hong Kong residents from 7,791 households. A higher-order model with 1 second-order factor and 5 first-order factors fit the data well and showed factorial invariance across sex and participants in different family roles. A 5-item short form (FHS-5) was also developed, with 1 item from each first-order factor. The short scale showed, as expected, a single-factor structure with good fit. Both scales demonstrated high internal consistency, acceptable test-retest reliability, and good convergent and discriminant validity. The 24-item FHS was negatively associated with depressive symptoms after accounting for individual risk factors and general family function. Family harmony moderated the relationship between life stress and depressive symptoms such that those individuals who reported low family harmony had stronger associations between life stress and depressive symptoms. This study adds to the literature a systematically developed, multidimensional measure of family harmony, which may be an important psychological protective factor, in a large urban Chinese sample. The FHS-5 minimizes operational and respondent burdens, making it an attractive tool for large-scale epidemiological studies with Chinese populations in urban settings, where over half of China's 1.4 billion people reside.

Abstract
BACKGROUND Tobacco endgame policies are increasingly advocated to end tobacco use. This study investigated public support for a total ban on tobacco sales, use and possession in Hong Kong. METHODS A telephone survey was conducted among 1537 randomly selected residents in 2012 to assess their support for a total ban on tobacco sales, usage and possession. Information on sociodemographic characteristics, smoking, and second hand smoke exposure were collected. Logistic regression was used to investigate factors associated with support for a total ban. RESULTS Most of the never smokers (75.3%), ex-smokers (63.9%), and nearly half of current smokers (48.9%) backed some form of a total ban on tobacco. A total ban on tobacco sales was the most popular option among the three groups, with over half (64.8%) of all respondents supporting a ban within 10 years. Current smoking and higher educational attainment were associated with less support for a total ban on tobacco sales. Among current smokers, having quit intentions and attempts to quit were associated with support for a total ban. CONCLUSIONS A total ban on tobacco sales was supported by most respondents. Ex-smokers and current smokers also voiced substantial support, although less than never smokers. A total ban on tobacco sales before 2022 should be the goal as it is supported by most of the respondents. Interim tobacco control measures, such as tax increases, expansion of smoking cessation services and plain packaging should be implemented to help current smokers quit and reduce smoking initiation before implementation of the ban.

Abstract
BACKGROUND Inequalities in Internet use and health information seeking are well documented, but less is known about information for family life activities. OBJECTIVE We investigated the social determinants of online family life information seeking behaviors and its associations with family well-being among Chinese adults in Hong Kong. METHODS A probability-based telephone survey was conducted in 2012 to record family life information seeking behaviors, including frequency of seeking and paying attention to family life information, levels of trust, and perceived usefulness of family life information. Family well-being was assessed using 3 single items on perceived family harmony, happiness, and health, with higher scores indicating greater well-being. Adjusted odds ratios for family life information seeking behaviors by socioeconomic characteristics and lifestyle behaviors, and adjusted beta coefficients for family well-being by family life information seeking behaviors were calculated. RESULTS Of 1537 respondents, 57.57% (855/1537) had ever and 26.45% (407/1537) sought monthly family life information through the Internet. Lower educational attainment and household income, smoking, and physical inactivity were associated with less frequent seeking and paying attention (all P<.05). Greater perceived family health was associated with more frequent attention (adjusted β=.32, 95% CI.11-.52), greater levels of trust (adjusted β=.28, 95% CI .07-.48), and perceived usefulness (adjusted β=.23, 95% CI .01-.45) of family life information. Frequent attention and higher level of trust were also associated with greater family harmony (adjusted β=.22, 95% CI .002-.41) and happiness (adjusted β=.23, 95% CI .003-.42), respectively. CONCLUSIONS This is the first study investigating family life information seeking behaviors and suggested inequalities of online family life information seeking behaviors. The association between family life information seeking behavior and family well-being needs to be confirmed in prospective studies.

Abstract
AIM To investigate the cross-sectional association between smoking and happiness in Chinese adults in Hong Kong. DESIGN, SETTING AND PARTICIPANTS Telephone surveys were conducted between 2009 and 2012, with 4553 randomly sampled Chinese adults (male 54%, mean age 58.3 years) in Hong Kong. MEASUREMENTS Happiness was measured using the four-item Subjective Happiness Scale (SHS) and single-item Global Happiness Item (GHI). Smoking status was categorized as current smokers (7.7%%), ex-smokers (6.5%, 93% quit for >6 months) and never smokers (85.8%). Linear and ordinal logistic regressions were used to calculate adjusted β-coefficients for SHS and proportional adjusted odds ratios (aOR) for GHI in relation to smoking. FINDINGS Compared with current smokers, ex-smokers enjoyed greater happiness according to both SHS (adjusted β = 0.16, P < 0.05) and GHI (aOR = 1.52, P < 0.05) measurements, but current and never smokers were similar. Among current smokers, the number of cigarettes smoked was not associated with happiness, but the lack of any attempt to quit was associated significantly with greater happiness (adjusted β = 0.31 for SHS, aOR = 1.82 for GHI) compared with smokers who had tried to quit but not succeeded. Smokers not intending to quit in the next 6 months had higher odds of happiness (GHI) than those wanting to quit within 6 months (aOR = 1.86, P < 0.05). CONCLUSIONS Ex-smokers in Hong Kong are happier than current smokers and never smokers, whose happiness measurements are similar. Causal associations have yet to be established.

Abstract
Background Obesity is increasing dramatically in the Asia-Pacific region particularly China. The population of Hong Kong was exposed to modernization far earlier than the rest of China, reflecting conditions that are likely to be replicated as other Chinese cities undergo rapid change. This study examined the relationship between television viewing and obesity in a Hong Kong sample. Information about the relationship between a key sedentary behavior, TV viewing, and obesity, and its moderation by demographic characteristics may identify sectors of the population at highest risk for excess weight. Methods Data were from Hong Kong Family and Health Information Trends Survey (2009–2010), a population-based survey on the public's use of media for health information and family communication by telephone interviews with 3,016 Hong Kong adults (age≥18 years). TV viewing time, body mass index (BMI), physical activity and other lifestyle variables were analyzed. Results Viewing time was longer in women, increased with age but decreased with education level and vigorous physical activity (all P<0.01). Longer TV viewing time was significantly associated with higher BMI (Coefficients B = 0.17, 95% CI: 0.11, 0.24) after adjusting for age, gender, employment status, marital status, education level, smoking activity and vigorous physical activity. This association was stronger in women than men (Coefficients B: 0.19 versus 0.15) and strongest in those aged 18 to 34 years (Coefficients B = 0.35). Furthermore, an hour increase in daily TV viewing was associated with 10% greater odds of being obese. Conclusions A significant socioeconomic gradient in television viewing time was observed. TV viewing time positively associated with BMI and obesity. The TV viewing – BMI associations were strongest in women and young adults, suggesting vulnerable groups to target for obesity prevention by decreasing TV viewing.

Abstract
Background Poor self-rated health (SRH) is socially patterned with health communication inequalities, arguably, serving as one mechanisms. This study investigated the effects of health information seeking on SRH, and its mediation effects on disparities in SRH. Methods We conducted probability-based telephone surveys administered over telephone in 2009, 2010/11 and 2012 to monitor health information use among 4553 Chinese adults in Hong Kong. Frequency of information seeking from television, radio, newspapers/magazines and Internet was dichotomised as <1 time/month and ≥1 time/month. Adjusted odds ratios (aOR) for poor SRH were calculated for health information seeking from different sources and socioeconomic status (education and income). Mediation effects of health information seeking on the association between SES and poor SRH was estimated. Results Poor SRH was associated with lower socioeconomic status (P for trend <0.001), and less than monthly health information seeking from newspapers/magazines (aOR = 1.23, 95% CI 1.07–1.42) and Internet (aOR = 1.13, 95% CI 0.98–1.31). Increasing combined frequency of health information seeking from newspapers/magazines and Internet was linearly associated with better SRH (P for trend <0.01). Health information seeking from these two sources contributed 9.2% and 7.9% of the total mediation effects of education and household income on poor SRH, respectively. Conclusions Poor SRH was associated with lower socioeconomic status, and infrequent health information seeking from newspapers/magazines and Internet among Hong Kong Chinese. Disparities in SRH may be partially mediated by health information seeking from newspapers/magazines and Internet.
