Layperson-Delivered Telephone-Based Behavioral Activation Among Low-Income Older Adults During the COVID-19 Pandemic: The HEAL-HOA Randomized Clinical Trial.

Importance: Older adults are particularly vulnerable to loneliness and its physical and psychosocial sequelae, but scalable interventions are lacking, especially during disasters such as pandemics. Objective: To compare the effects of layperson-delivered, telephone-based behavioral activation and mindfulness interventions vs telephone-based befriending on loneliness among at-risk older adults. Design, Setting, and Participants: This assessor-blinded, 3-arm randomized clinical trial screened Chinese older adults through household visits and community referrals from April 1, 2021, to April 30, 2023, in Hong Kong. Eligible participants (≥65 years of age) who were lonely, digitally excluded, living alone, and living below the poverty line and provided consent to participate were randomized into behavioral activation, mindfulness, and befriending groups. Assessments were conducted at baseline, 1 month, and 3 months. Intervention: As part of the Helping Alleviate Loneliness in Hong Kong Older Adults (HEAL-HOA) dual randomized clinical trial, 148 older laypersons were trained to deliver a twice-weekly 30-minute intervention via telephone for 4 weeks. Main Outcomes and Measures: The primary outcome was loneliness measured by the UCLA Loneliness Scale (range, 20-80) and the De Jong Gierveld Loneliness Scale (range, 0-6), with higher scores on both scales indicating greater loneliness. Secondary outcomes were depression, perceived stress, life satisfaction, psychological well-being, sleep quality, perceived social support, and social network. Results: A total of 1151 participants (mean [SD] age, 76.6 [7.8] years; 843 [73.2%] female) were randomized to the behavioral activation (n = 335), mindfulness (n = 460) or befriending (n = 356) group. Most were widowed or divorced (932 [81.0%]), had primary education or below (782 [67.9%]), and had 3 or more chronic diseases (505 [43.9%]). Following intention-to-treat principles, linear mixed-effects regression model analyses showed that loneliness measured by the UCLA Loneliness Scale was significantly reduced in the behavioral activation group (mean difference [MD], -1.96 [95% CI, -3.16 to -0.77] points; P < .001]) and in the mindfulness group (MD, -1.49 [95% CI, -2.60 to -0.37] points; P = .004) at 3 months compared with befriending. Loneliness measured by the De Jong Gierveld Loneliness Scale was not significantly reduced at 3 months in the behavioral activation group (MD, -0.06 [95% CI, -0.26 to 0.13] points; P > .99]) but was in the mindfulness group (MD, 0.22 [95% CI, 0.03 to 0.40] points; P = .01) at 3 months compared with befriending. In the behavioral activation and mindfulness groups, sleep quality improved compared with befriending, but perceived stress increased. Psychological well-being and perceived social support improved in the behavioral activation group. No statistically significant between-group differences were observed in depression, life satisfaction, or social network. Conclusion and Relevance: In this randomized clinical trial, scalable psychosocial interventions delivered remotely by older laypersons appeared promising in reducing later life loneliness and addressing the pressing mental health challenges faced by aging populations and professional geriatric mental health workforce shortages. Further research should explore ways to maximize the clinical relevance and cost-effectiveness of these interventions.

Suicide prevention in Hong Kong: pushing boundaries while building bridges.

Hong Kong is a natural laboratory for studying suicides-small geographic footprint, bustling economic activity, rapidly changing socio-demographic transitions, and cultural crossroads. Its qualities also intensify the challenges posed when seeking to prevent them. In this viewpoint, we showed the research and practices of suicide prevention efforts made by the Hong Kong Jockey Club Centre for Suicide Research and Prevention (CSRP), which provide the theoretical underpinning of suicide prevention and empirical evidence. CSRP adopted a multi-level public health approach (universal, selective and indicated), and has collaboratively designed, implemented, and evaluated numerous programs that have demonstrated effectiveness in suicide prevention and mental well-being promotion. The center serves as a hub and a catalyst for creating, identifying, deploying, and evaluating suicide prevention initiatives, which have the potential to reduce regional suicides rates when taken to scale and sustained.

Study protocol of the 'HEAL-HOA' dual randomized controlled trial: Testing the effects of volunteering on loneliness, social, and mental health in older adults.

Background: Interventions to reduce loneliness in older adults usually do not show sustained effects. One potential way to combat loneliness is to offer meaningful social activities. Volunteering has been suggested as one such activity - however, its effects on loneliness remain to be tested in randomized controlled trials (RCT). Methods: This planned Dual-RCT aims to recruit older adults experiencing loneliness, with subsequent randomization to either a volunteering condition (6 weeks of training before delivering one of three tele-based loneliness interventions to older intervention recipients twice a week for 6 months) or to an active control condition (psycho-education with social gatherings for six months). Power analyses require the recruitment of N = 256 older adults to detect differences between the volunteering and the active control condition (128 in each) on the primary outcome of loneliness (UCLA Loneliness Scale). Secondary outcomes comprise social network engagement, perceived social support, anxiety and depressive symptoms, self-rated health, cognitive health, perceived stress, sleep quality, and diurnal cortisol (1/3 of the sample). The main analyses will comprise condition (volunteering vs. no-volunteering) × time (baseline, 6-, 12-, 18-, 24-months follow-ups) interactions to test the effects of volunteering on loneliness and secondary outcomes. Effects are expected to be mediated via frequency, time and involvement in volunteering. Discussion: If our trial can show that volunteers delivering one of the three telephone-based interventions to lonely intervention recipients benefit from volunteer work themselves, this might encourage more older adults to volunteer, helping to solve some of the societal issues involved with rapid demographic changes.

Effects of volunteering over six months on loneliness, social and mental health outcomes among older adults: The HEAL-HOA Dual Randomized Controlled Trial.

OBJECTIVE: To determine the beneficial effects of volunteering as lay counselor via telephone on own loneliness, social network engagement, perceived social support, stress, anxiety, and depressive symptoms among Chinese older adults in Hong Kong during the COVID-19 pandemic. DESIGN, SETTING, INTERVENTION, AND PARTICIPANTS: "Helping Alleviate Loneliness in Hong Kong Older Adults" (HEAL-HOA), a dual randomized controlled trial, was implemented to test effects of telephone-based psychosocial interventions delivered by older-adult volunteers for low-income lonely older adults. To evaluate the effects of volunteering on loneliness, we randomized 375 individuals ages 50-70 into a volunteering condition versus an active control (psychoeducation with social gatherings). Following a 6-week training, participants in the volunteering condition, delivered tele-interventions to older intervention recipients. MEASUREMENT: The primary outcome was loneliness measured with the UCLA Loneliness Scale. Secondary outcomes were loneliness measured with the De Jong Gierveld Scale (DJG), social network engagement, perceived social support, perceived stress, anxiety, and depressive symptoms. Assessments were completed before training (baseline) and immediately after the 6-month volunteering period. RESULTS: Results from linear mixed models show significant positive effects of volunteering (significant interactions of condition × time) on both measures of loneliness (dppc2 = -0.41 ULCA Loneliness score, dppc2 = -0.70 total DJG score), social network engagement, stress and depressive symptoms as compared to control participants. CONCLUSIONS: The HEAL-HOA trial demonstrates beneficial effects of volunteer-delivered tele-interventions on decreasing loneliness on the volunteer interventionists themselves. Communicating these benefits for volunteers may attract more older adults into volunteering. This effective tele-based volunteer program is scalable for wider implementation. SUMMARY: This RCT tested effects of volunteering on loneliness in Hong Kong during the COVID-19-pandemic. Three hundred seventy-five individuals ages 50-70 were randomized into volunteering (delivering tele-interventions against loneliness) versus an active control condition. After 6 months, volunteers compared to controls, showed benefits on loneliness, social network engagement, stress and depressive symptoms. A program engaging lonely older adults in loneliness intervention delivery has beneficial effects on volunteers themselves and could be a scalable solution for our loneliness epidemic.

Protocol for a mixed-methods randomised controlled trial evaluating the effectiveness of a dyadic expressive arts-based intervention in improving the psychosocial well-being of children with intellectual disability in special schools and their mothers.

INTRODUCTION: Mothers of children with intellectual disability (ID) are often distressed because of intensive workloads and difficulties in communicating with their children. Given the interdependence between the psychosocial well-being of such dyads, interventions that promote parent-child relationships and mutual communication would be beneficial. Arts provide alternative avenues for expression and offer an imaginative and playful environment for discovering new communication strategies. Given the lack of studies on arts-based dyadic interventions, this study aims to examine the effectiveness of dyadic expressive arts-based intervention (EXAT) in improving the psychosocial outcomes of children with ID and their mothers and the mother-child relationships. METHODS AND ANALYSIS: This study will adopt a mixed-methods randomised controlled trial design, wherein 154 dyads of children with ID and their mothers will be randomised into either the dyadic EXAT group or the treatment-as-usual waitlist control group. Quantitative data will be collected at four time points: baseline (T0), postintervention (T1), 3-month postintervention (T2) and 6-month postintervention (T3). Qualitative data will be collected from a subset of 30 mothers in the intervention group at T1 and T3 to document their experiences and perceived changes after the intervention. Mixed-effects models and path analysis will be adopted to analyse the quantitative data, whereas thematic analysis will be applied to the qualitative data. Both sets of data will be triangulated for an integrated view of the effectiveness and mechanism of the intervention. ETHICS AND DISSEMINATION: Ethical approval has been obtained from the Human Research Ethics Committee of the University of Hong Kong (Ref. no.: EA200329). Written consent forms will be obtained from all recruited participants (mothers, children with ID and teachers/social workers) before data collection. The study findings will be disseminated in international conferences and peer-reviewed academic journals. TRIAL REGISTRATION NUMBER: NCT05214859.

A randomized controlled trial on the effects and acceptability of individual mindfulness techniques - meditation and yoga - on anxiety and depression in people with Parkinson's disease: a study protocol.

BACKGROUND: Between 40 and 50% of patients with Parkinson's disease (PD) experience anxiety and depression, associated with impaired physical function, high care dependency and mortality. Recently, the United States National Institutes of Health has urged the implementation of mindfulness practices in chronic illness care. Most research to date has examined the effects on chronically ill patients of complex interventions using a combination of mindfulness techniques. In PD patients, however, such complex modalities appear to hinder the technique mastery. Hence, the aim of this trial is to investigate the effects and underlying mechanism of individual mindfulness techniques among PD patients, as well as exploring participants' experience in using individual mindfulness techniques as a lifestyle intervention for stress and symptom management. METHODS: We will conduct an assessor-blind three-arm randomized waitlist-controlled trial with a descriptive qualitative evaluation. Up to 168 PD patients will be recruited from community settings and out-patient clinics, and randomized to meditation, yoga, or usual care group. Meditation and yoga sessions of 90-minute are held weekly for 8 weeks. Primary outcomes include anxiety and depression. Secondary outcomes include PD-related motor and non-motor symptoms and quality-of-life; and level of mindfulness and biomarkers of stress and inflammatory responses will be measured as mediating variables. All outcome evaluations will be assessed at baseline, 8 weeks, and 24 weeks. Following the intention-to-treat principle, generalized estimating equation models and path analysis will be used to identify the treatment effects and the mediating mechanisms. A subsample of 30 participants from each intervention group will be invited for qualitative interviews. DISCUSSION: The study would also generate important insights to enhance the patients' adaptation to debilitating disease. More specifically, symptom management and stress adaptation are highly prioritized healthcare agenda in managing PD. The research evidence will further inform the development of community-based, nurse-led compassionate care models for neurodegenerative conditions, which is complementary to existing health services.

What Is Known From the Published Literature About Yoga Interventions Delivered in Community Settings for Older Adults? A Systematic Scoping Review.

In recent years, mind-body exercises have arisen as a popular type of physical exercise among older adults in both Eastern and Western countries. In the last 10 years, yoga has been established as a key physical activity intervention for older adults. Thus, the literature on yoga interventions delivered in community settings for older adults warrants a formal appraisal. This scoping review synthesized information on intervention contents and outcomes and summarized data on attrition, adherence, and adverse events for community health practitioners. In addition, this review used the Template for Intervention Description and Replication and the Population, Intervention, Comparator, Outcome checklist to identify areas of depth and gaps in the literature on yoga interventions.

Recovery beyond functional restoration: a systematic review of qualitative studies of the embodied experiences of people who have survived a stroke.

OBJECTIVE: To synthesise the qualitative evidence of embodied experiences of people who have survived a stroke, the experiences of making sense of oneself, others and the world in the poststroke bodies.DesignQualitative systematic review. DATA SOURCES: Five electronic databases, PsycINFO, PubMed, MEDLINE, CINAHL Plus and Cochrane Library, were employed to search for qualitative studies published up to February 2022. INCLUSION CRITERIA: Literature in English that employed qualitative methods to investigate the embodied experiences of people who have survived a stroke. QUALITY APPRAISAL: Two reviewers independently appraised the quality of the included studies based on the tool developed by Salter et al in 2008. It consists of seven questions assessing the credibility and relevance of the studies. Discrepancies were resolved until a consensus was reached. DATA EXTRACTION AND SYNTHESIS: Thematic synthesis was applied to synthesise the related findings from all the included studies. Two reviewers were involved in the process. RESULTS: 1482 records were identified. After the screening process, 34 studies were included in this review. Three analytical themes and their related descriptive themes emerged. Analytical themes included 'disconnection between oneself, others and the world,' 'the transitional period: exploring and negotiating,' and 'reconnecting with oneself, others and the world'. CONCLUSION: The findings demonstrated that the embodied experiences of people who have survived a stroke progressed from feeling disconnected to reconnecting with themselves, others and the world. Stroke recovery should not only be limited to functional restoration. Approaching 're-embodiment', the realignment between oneself and one's body, is crucial in reintegrating with others and the world on the trajectory toward recovery.

The Prevalence of Bullying Victimization and Perpetration Among the School-Aged Population in Chinese Communities: A Systematic Review and Meta-Analysis.

Though bullying was predominantly documented in Western societies, increasing attention has been paid to bullying in Chinese communities during recent years. It remains unknown whether bullying among youngsters in the Chinese communities is similar to or different from their counterparts in Western societies. A systematic review was primarily conducted in English and Chinese databases from the start to December 31, 2021. This study estimated the prevalence of overall (integrating both face-to-face and cyber forms), face-to-face, and cyber bullying victimization and perpetration using random-effects models. Based on 68 eligible studies, this study revealed a pooled prevalence of overall bullying victimization of 22.7% (95% Confidence Interval [CI] [17.7, 28.6]) and a pooled prevalence of overall bullying perpetration of 15.7% (95% CI [6.7, 32.3]). Besides, the estimated prevalence were 20.8% and 10.3% for face-to-face bullying victimization and perpetration, while 9.6% and 8.4% for cyberbullying victimization and perpetration. The subgroup analyses showed that the high heterogeneity of prevalence among the studies estimating bullying victimization and perpetration could be accounted for by sample characteristics and the measurement approaches. This study suggests that bullying is prevalent in the Chinese communities, comparable to, if not higher than, in the Western societies. Prevention and intervention programs are urgently required to reduce bullying among the school-aged population in Chinese communities.

Including formal and informal caregivers in the development of Play Intervention for Dementia: a qualitative study.

BACKGROUND: Play Intervention for Dementia is a practice initiative using play to help people living with dementia (PWD) experience engagements, autonomy, and cognitive stimulation. This program was developed under a participatory paradigm, with extensive contribution from formal and informal caregivers. This article describes how caregivers contributed to the practice principles, materials, and assessment during the development phase of Play Intervention for Dementia through community-based participatory research (CBPR). METHODS: Three service supervisors, 16 formal caregivers and 14 informal caregivers from the community participated in this study. Based on CBPR, the study progressed in a reflexive, iterative and collaborative way. Data were collected from diverse sources, including practice journals, observation notes and reflexive focus group interviews. Two trained qualitative researchers conducted thematic analysis on the data collected, with focus on practical skills, outcomes, and caregivers' general experience during the intervention. RESULTS: The therapeutic and liberating power of play was thoroughly discussed by the caregivers. They considered play as an innovative way to understand, engage, and connect with the PWD. Also, improvement in energy level, motivation and communicative capacity was observed among the PWD. The researcher and caregivers collaboratively refined and designed the protocol of Play Intervention for Dementia, adding localized principles and games to the original design. CONCLUSION: Caregivers found play to be a meaningful way to engage with PWD, as it provided an equal platform for them. The intervention also enabled them to reflect upon ageing and disease at a deeper level. Caregivers have contributed significantly to the refinement and contextualisation of the intervention. The efficiency of the refined program should be further tested on a larger scale.

Creating Exercise Spaces in Parks for Older Adults With Fitness, Rehabilitation, and Play Elements: A Review and Perspective.

Parks usually create a protective playground space for children to perform physical activity like jumping, running, and climbing. Specific spaces have rarely been created for older adults to perform physical activity in public parks. Now that park designs increasingly include outdoor exercise spaces for older adults, yet the important elements or considerations when designing this space remain unclear. Here, we present the emerging importance of and evidence for creating well-designed activity spaces for senior citizens in public parks in the era of population aging.

Positive Coping as a Mediator of Mobile Health Intervention Effects on Quality of Life Among People Living With HIV: Secondary Analysis of the Randomized Controlled Trial Run4Love.

BACKGROUND: The effectiveness of psychosocial interventions on quality of life (QOL) among people living with HIV has been validated, including mobile health (mHealth) interventions. However, it is unclear which components of such interventions account for these effects. OBJECTIVE: This study aims to examine positive coping as a potential mediator of the effects of an mHealth intervention on QOL among people living with HIV. METHODS: For this secondary analysis, we used data from an mHealth-based randomized controlled trial, Run4Love, which was conducted to improve QOL and mental health outcomes of people living with HIV. A total of 300 participants were randomly assigned to the intervention group to receive the adapted cognitive-behavioral stress management courses and regular physical activity promotion or the waitlist control group in a 1:1 ratio. Our analysis focused on positive coping and QOL, which were repeatedly measured at baseline and at 3-, 6-, and 9-month follow-ups. Latent growth curve models were constructed to explore the mediating role of positive coping in the effects of the mHealth intervention on QOL. RESULTS: Positive coping served as a mediator in the effect of the mHealth intervention on QOL for up to 9 months. The mHealth intervention had a significant and positive indirect effect on the slope of QOL via the slope of positive coping (b=2.592×1.620=4.198, 95% CI 1.189-7.207, P=.006). The direct effect of the intervention was not significant (b=0.552, 95% CI -2.154 to 3.258, P=.69) when controlling for the mediator. CONCLUSIONS: The longitudinal findings suggest that positive coping could be a crucial mediator of the mHealth intervention in enhancing QOL among people living with HIV. These findings underscore the importance of improving positive coping skills in mHealth interventions to improve QOL among people living with HIV.

Engaging community-dwelling older adults as co-developers in a public outdoor exercise facilities-based physical activity education intervention: A mixed-method participatory study in Hong Kong.

In Hong Kong, an increasing number of outdoor exercise facilities have been established in public open spaces to promote physical activity (PA) in older adults. However, no intervention is dedicated in educating the public on how to make use of these resources to fulfil the PA guidelines based on behavioural change theory. This study has two phases, phase one aims to describe the participatory development of the intervention, and phase two is the evaluation of a public outdoor exercise facilities-based PA education intervention for community-dwelling older adults. A mixed-methods participatory design was used to evaluate the impact of the intervention. PA behaviour was assessed as the fulfilment of the PA recommendations by World Health Organization, and the Rapid Assessment of Physical Activity (RAPA) scale at baseline, immediately, and 3 and 6 months post-intervention. Psychosocial constructs and physical assessments were carried out at both pre- and post-intervention. Individual in-depth interviews were conducted at post-intervention. Forty-seven participants were enrolled in the intervention. The average adherence rate was 90.87%. PA significantly increased after the intervention and remained elevated for the following 6 months. Post-intervention, the qualitative findings supported the quantitative findings at both the individual and social levels. However, findings regarding the change in participants' usage of environmental resources were divergent. The intervention was well-received by the participating older adults, as reflected by the high adherence rate. Both quantitative and qualitative data demonstrated the overall impacts of the intervention for creating sustainable changes in PA behaviour.

From Therapeutic Factors to Mechanisms of Change in the Creative Arts Therapies: A Scoping Review.

Empirical studies in the creative arts therapies (CATs; i.e., art therapy, dance/movement therapy, drama therapy, music therapy, psychodrama, and poetry/bibliotherapy) have grown rapidly in the last 10 years, documenting their positive impact on a wide range of psychological and physiological outcomes (e.g., stress, trauma, depression, anxiety, and pain). However, it remains unclear how and why the CATs have positive effects, and which therapeutic factors account for these changes. Research that specifically focuses on the therapeutic factors and/or mechanisms of change in CATs is only beginning to emerge. To gain more insight into how and why the CATs influence outcomes, we conducted a scoping review (N studies = 67) to pinpoint therapeutic factors specific to each CATs discipline, joint factors of CATs, and more generic common factors across all psychotherapy approaches. This review therefore provides an overview of empirical CATs studies dealing with therapeutic factors and/or mechanisms of change, and a detailed analysis of these therapeutic factors which are grouped into domains. A framework of 19 domains of CATs therapeutic factors is proposed, of which the three domains are composed solely of factors unique to the CATs: "embodiment," "concretization," and "symbolism and metaphors." The terminology used in change process research is clarified, and the implications for future research, clinical practice, and CATs education are discussed.

A randomised controlled trial of expressive arts-based intervention for young stroke survivors.

BACKGROUND: Stroke causes lasting brain damage that has numerous impacts on the survivor's physical, psychosocial, and spiritual well-being. Young survivors (< 65 years old) tend to suffer more because of their longer overall survival time. Expressive arts-based intervention is considered a holistic approach for stroke rehabilitation because it allows participants to express their thoughts and emotions through the arts. The group environment also promotes mutual support among participants. The creative art-making process helps expand participants' creativity and imagination as well as promote a sense of aesthetic appreciation. Previous studies have shown the effectiveness of the arts-based intervention in managing stroke and its psychosocial-spiritual comorbidities. Nevertheless, a systematic study has not been conducted, including in young survivors. This trial plans to investigate the effectiveness of an expressive arts-based intervention on bio-psychosocial-spiritual outcomes in young Chinese stroke survivors. METHODS/DESIGN: A single-blind, two-arm cluster randomised control trial with a waitlist control design will be adopted. One hundred and fifty-four stroke survivors, aged 18-64 years with modified Rankin Scale scores of 1-4, will be screened and randomised to either an expressive arts-based intervention group or a treatment-as-usual waitlist control group. The intervention group will receive a 90-min session once a week for a total of 8 weeks. All participants will be assessed three times: at baseline, 8 weeks, and 8 months after the baseline. Study outcomes include measures of depression and anxiety, perceived stress, perceived social support, hope, spiritual well-being, quality of life, salivary cortisol, blood pressure, and heart rate. DISCUSSION: This study is expected to contribute to the current knowledge on the effectiveness of an arts-based intervention on the holistic wellness of young stroke survivors. The findings will help stroke survivors and healthcare professionals make better choices in selecting practices that will yield maximum benefits, satisfaction, adherence, and sustainability. In addition, the examination of the relationships between bio-psychosocial-spiritual variables will help contribute to the development of holistic care for the survivors.

Exercise Spaces in Parks for Older Adults: A Qualitative Investigation.

In response to demographic changes in recent years, an increasing number of parks have established exercise spaces for older adults. However, limited research has been conducted to investigate how older adults utilize, experience, and perceive these spaces. This study aims to explore their experiences of using these spaces and their perspectives on these spaces by using a qualitative descriptive research design. In-depth interviews were conducted with 32 users in three Hong Kong parks with low, medium, and high area-based socioeconomic statuses. The findings highlight that exercise spaces in parks can cultivate a positive environment allowing older adults with varying physical abilities and health statuses to remain active together as well as to support each other socially and emotionally in a natural outdoor setting. The participants' perspectives on the exercise space discussed in this study suggest that future plans for constructing such spaces in parks might benefit from a co-design approach.

Relationship Between Patient Engagement and Depressive Symptoms Among People Living With HIV in a Mobile Health Intervention: Secondary Analysis of a Randomized Controlled Trial.

BACKGROUND: Associations between higher levels of patient engagement and better health outcomes have been found in face-to-face interventions; studies on such associations with mobile health (mHealth) interventions have been limited and the results are inconclusive. OBJECTIVE: The objective of this study is to investigate the relationship between patient engagement in an mHealth intervention and depressive symptoms using repeated measures of both patient engagement and patient outcomes at 4 time points. METHODS: Data were drawn from a randomized controlled trial (RCT) of an mHealth intervention aimed at reducing depressive symptoms among people living with HIV and elevated depressive symptoms. We examined the association between patient engagement and depressive symptoms in the intervention group (n=150) where participants received an adapted cognitive-behavioral stress management (CBSM) course and physical activity promotion on their WeChat social media app. Depressive symptoms were repeatedly measured using the Patient Health Questionnaire (PHQ-9) at baseline and 1 month, 2 months, and 3 months. Patient engagement was correspondingly measured by the completion rate, frequency of items completed, and time spent on the program at 1 month, 2 months, and 3 months. Latent growth curve models (LGCMs) were used to explore the relationship between patient engagement and depressive symptoms at multiple time points in the intervention. RESULTS: The mean PHQ-9 scores were 10.2 (SD 4.5), 7.7 (SD 4.8), 6.5 (SD 4.7), and 6.7 (SD 4.1) at baseline, 1 month, 2 months, and 3 months, respectively. The mean completion rates were 50.6% (SD 31.8%), 51.5% (SD 32.2%), and 50.8% (SD 33.7%) at 1, 2, and 3 months, respectively; the average frequencies of items completed were 18.0 (SD 14.6), 32.6 (SD 24.8), and 47.5 (SD 37.2) at 1, 2, and 3 months, respectively, and the mean times spent on the program were 32.7 (SD 66.7), 65.4 (SD 120.8), and 96.4 (SD 180.4) minutes at 1, 2, and 3 months, respectively. LGCMs showed good model fit and indicated that a higher completion rate (ß at 3 months=-2.184, P=.048) and a greater frequency of items completed (ß at 3 months=-0.018, P=.04) were associated with fewer depressive symptoms at 3 months. Although not significant, similar trends were found in the abovementioned relationships at 1 and 2 months. There was no significant relationship between time spent on the program and depressive symptoms. CONCLUSIONS: This study revealed a positive association between patient engagement and health outcomes at 3 months of an mHealth intervention using LGCMs and repeated measures data. The results underscore the importance of improving patient engagement in mHealth interventions to improve patient-centered health outcomes.

Development and Feasibility of a Mobile Health-Supported Comprehensive Intervention Model (CIMmH) for Improving the Quality of Life of Patients With Esophageal Cancer After Esophagectomy: Prospective, Single-Arm, Nonrandomized Pilot Study.

BACKGROUND: Patients with esophageal cancer often experience clinically relevant deterioration of quality of life (QOL) after esophagectomy owing to malnutrition, lack of physical exercise, and psychological symptoms. OBJECTIVE: This study aimed to evaluate the feasibility, safety, and efficacy of a comprehensive intervention model using a mobile health system (CIMmH) in patients with esophageal cancer after esophagectomy. METHODS: Twenty patients with esophageal cancer undergoing the modified McKeown surgical procedure were invited to join the CIMmH program with both online and offline components for 12 weeks. The participants were assessed before surgery and again at 1 and 3 months after esophagectomy. QOL, depressive symptoms, anxiety, stress, nutrition, and physical fitness were measured. RESULTS: Of the 20 patients, 16 (80%) completed the program. One month after esophagectomy, patients showed significant deterioration in overall QOL (P=.02), eating (P=.005), reflux (P=.04), and trouble with talking (P<.001). At the 3-month follow-up, except for pain (P=.02), difficulty with eating (P=.03), dry mouth (P=.04), and trouble with talking (P=.003), all other QOL dimensions returned to the preoperative level. There were significant reductions in weight (P<.001) and BMI (P=.02) throughout the study, and no significant changes were observed for physical fitness measured by change in the 6-minute walk distance between baseline and the 1-month follow-up (P=.22) or between baseline and the 3-month follow-up (P=.52). Depressive symptoms significantly increased 1 month after surgery (P<.001), while other psychological measures did not show relevant changes. Although there were declines in many measures 1 month after surgery, these were much improved at the 3-month follow-up, and the recovery was more profound and faster than with traditional rehabilitation programs. CONCLUSIONS: The CIMmH was feasible and safe and demonstrated encouraging efficacy testing with a control group for enhancing recovery after surgery among patients with esophageal cancer in China.

Hot Weather and Suicide Deaths among Older Adults in Hong Kong, 1976-2014: A Retrospective Study.

Findings of the association between hot weather and suicide in a subtropical city such as Hong Kong are inconsistent. This study aimed to revisit the association by identifying meteorological risk factors for older-adult suicides in Hong Kong using a time-series approach. A retrospective study was conducted on older-adult (aged ≥65) suicide deaths in Hong Kong from 1976 to 2014. Suicides were classified into those involving violent methods and those involving nonviolent methods. Meteorological data, including ambient temperature, were retrieved. Transfer function time-series models were fitted. In total, 7314 older-adult suicide deaths involving violent methods and 630 involving nonviolent methods were recorded. For violent-method suicides, a monthly average daily minimum ambient temperature was determined to best predict the monthly rate, and a daily maximum ambient temperature of 30.3 °C was considered the threshold. For suicide deaths involving nonviolent methods, the number of days in a month for which the daily maximum ambient temperature exceeded 32.7 °C could best predict the monthly rate. Higher ambient temperature was associated with more older-adult suicide deaths, both from violent and nonviolent methods. Weather-focused preventive measures for older-adult suicides are necessary, such as the provision of more public air-conditioned areas where older adults can shelter from extreme hot weather.
