RESUMO
Dementia rates within Australian Aboriginal and Torres Strait Islander populations are estimated to be three to five times higher than non-Indigenous populations. Geographical and cultural barriers demand creative ways of delivering culturally appropriate effective dementia care. Focus groups and interviews with people (N = 73) from three Aboriginal Medical Services and communities explored attitudes toward, and experiences of dementia care and services. A thematic analysis highlighted the juxtaposition between biomedical and culturally appropriate models of dementia care. Services at the cultural interface can be adapted to facilitate appropriate dementia care at a local level allowing people to stay on Country, supported by people within one's own Community.

Positive psychology interventions are an effective means for cultivating flourishing, addressing low levels of wellbeing, and preventing languishing. Peer-led interventions can be a particularly advantageous delivery method of positive psychology interventions, as participants tend to respond more favourably to people that they can identify with personally. Such interventions have been applied in a variety of settings and populations, but the literature on peer-led positive psychology interventions has not yet been summarised. This paper provides a narrative overview of peer-led positive psychology interventions. We reviewed relevant peer-led interventions, assessed the available evidence on their effectiveness, and highlighted promising opportunities for peer-led positive psychology interventions. We found that the majority of the studies were observational in design but showed a high level of acceptability for participants across the reviewed domains. In particular, schools, workplaces, the aged care sector, and community settings are noted as promising target domains for these interventions. However, more studies-particularly high-quality research-will be needed to comprehensively test the effectiveness of peer-led positive psychology interventions. We discuss opportunities for future research in this field.

PURPOSE: This review aimed to document the characteristics and appraise the quality of dementia applications (apps) to support persons living with dementia and their caregivers. MATERIALS AND METHODS: Systematic searches of the Australian-based Google Play Store, Apple App Store, and relevant websites sought apps with dementia or Alzheimer's information, support for caregivers and persons living with dementia, or prevention content. Apps were screened and subsequently appraised via the mobile application review system (MARS). RESULTS: The majority of the final 75 dementia apps were free to download, but were only available on a single platform. Persons involved in caregiving were the primary audience. App content focused on dementia information, practical caregiving, and communication tips. Language options in addition to English were limited and few apps offered ongoing support. MARS appraisal identified few apps with good "Overall Quality" scores. Apps that were more comprehensive trended towards higher MARS scores. CONCLUSIONS: A composite lack of standardised quality indicators and commercial drivers of the marketplace present significant barriers for consumers seeking meaningful dementia information and support. Persons living with dementia and their caregivers would significantly benefit from social and organisational services that assist with navigating the app marketplace.Implications for rehabilitationThere is significant opportunity for quality digital innovations, including apps, to support home-based, independent dementia care.A composite lack of standardised quality indicators and commercial drivers of the app marketplace present significant barriers for persons living with dementia and their caregivers who seek apps with dementia information and support.Social and organisational services can support the dementia community through assistance with navigating the app marketplace for quality dementia information and support.

Retirement living (RL) communities may be an ideal setting in which to utilize peer-leaders to implement or support health and wellbeing interventions. To date, this literature has not been systematically summarized. The purpose of this study was to fill this gap with a particular focus on describing the extent to which interventions addressed each level of the social ecological model of behavior change. This review utilized established frameworks for assessing methodological quality of studies, including the CONSORT guidelines and RoB2 bias assessment for cluster randomized controlled trials. A total of 153 records were identified from database searches, and seven studies met inclusion criteria. Overall, there is emerging evidence that peer-led health and wellbeing programs in RL communities can positively impact both health behavior, such as increased physical activity or nutrition, and health status, such as lower blood pressure. The study quality was modest to very good, but only one study was deemed not to have a high risk of bias. Peers are generally cost-effective, more accessible, and relatable leaders for health interventions that can still produce impactful changes. Future studies are needed to better understand how to sustain promising interventions.

INTRODUCTION: Clinical facilitation is an established strategy for introducing innovation into clinical practice. The Queensland Centre for Perinatal and Infant Mental Health has used clinical facilitation to establish a telehealth service to support perinatal and infant mental health in regional, rural and remote areas of the Australian state of Queensland. The aim of this study is to explore the role of clinical facilitation in implementing and sustaining the telehealth service. METHODS: Semi-structured interviews were conducted with 14 remote-site users of the telehealth service. Interviews were analysed using thematic analysis. RESULTS: Two dominant themes emerged: unmet need and service visibility. The study confirms the usefulness of telehealth as a way to address unmet need for specialist mental health services in regional, rural and remote areas. The study also provides evidence that a telehealth service with intermittent demand requires a consistent clinical facilitator, to keep the service visible to remote-site clinicians and maintain awareness of the service as a referral option. CONCLUSION: Previous research has identified the importance of clinical facilitation in initial service implementation. This study demonstrates the necessity of clinical facilitation for ongoing service provision. Facilitation is likely to be more important where the telehealth service responds to intermittent or infrequent clinical need, compared with high-volume services where clinics are conducted routinely.

BACKGROUND: The ubiquitous presence and functionality of mobile devices offers the potential for mobile health (mHealth) to create equitable health opportunities. While mHealth is used among First Nations populations to respond to health challenges, the characteristics, uptake, and effectiveness of these interventions are unclear. OBJECTIVE: This review aimed to identify the characteristics of mHealth interventions (eg, study locations, health topic, and modality) evaluated with First Nations populations and to summarize the outcomes reported for intervention use, user perspectives including cultural responsiveness, and clinical effectiveness. In addition, the review sought to identify the presence of First Nations expertise in the design and evaluation of mHealth interventions with First Nations populations. METHODS: The methods of this systematic review were detailed in a registered protocol with the International Prospective Register of Systematic Reviews (PROSPERO, CRD42019123276). Systematic searches of peer-reviewed, scientific papers were conducted across 7 databases in October 2018. Eligible studies had a primary focus on mHealth interventions with experimental or quasi-experimental design to respond to a health challenge with First Nations people from Canada, Australia, New Zealand, and the United States. Two authors independently screened records for eligibility and assessed risk of bias using the Joanna Briggs Institute checklists. Data were synthesized narratively owing to the mix of study designs, interventions, and outcomes. The review was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. RESULTS: Searches yielded 1053 unique records, after review and screening, 13 studies (5 randomized controlled trials and 8 quasi-experimental designs) were included in the final analysis. Studies were conducted in Australia (n=9), the United States (n=2), and New Zealand (n=2). The most common health challenge addressed was mental health and suicide (n=5). Intervention modalities included text messaging (n=5), apps (n=4), multimedia messaging (n=1), tablet software (n=1), or a combination of short messaging service (SMS) and apps (n=1). Results showed mixed engagement with the intervention (n=3); favorable user perspectives, including acceptability and cultural appropriateness (n=6); and mixed outcomes for clinical effectiveness (n=10). A diverse range of risks of bias were identified, the most common of which included a lack of clarity about allocation and blinding protocols and group treatment for randomized controlled trials and a lack of control group and single outcome measures for quasi-experimental designs. First Nations expertise informed all mHealth studies, through authorship (n=8), affiliation with First Nations bodies (n=3), participatory study design (n=5), First Nations reference groups (n=5), or a combination of these. CONCLUSIONS: mHealth modalities, including SMS and apps, appear favorable for delivery of health interventions with First Nations populations, particularly in the area of mental health and suicide prevention. Importantly, First Nations expertise was strongly embedded within the studies, augmenting favorable use and user engagement. However, evidence of efficacy is limited.

Prolonged sitting is now recognized as an emergent work health and safety issue. To address the need for a scalable sitting-reduction intervention for workplaces, the BeUpstanding™ Champion Toolkit was developed. This free, online toolkit uses a 'train-the-champion' approach, providing a step-by-step guide and resources to workplace champions to assist them in raising awareness and building a supportive culture to reduce sitting time in their team. This qualitative study explored champion and staff perceptions of the beta (test) version of the toolkit. Seven work teams, from a range of workplace sectors (blue-/white-collar), sizes (small/medium/large) and locations (urban/regional) participated; all team members were exposed to the program (n = 603). Approximately 4 months after program initiation, semi-structured interviews were conducted with all champions (n = 7); focus groups were conducted with a random sample of staff (n = 40). Champions were followed-up again at 12 months (n = 5). Transcripts were coded by two researchers, with codes organized into overarching themes. All champions found the 'train-the-champion' approach, and the toolkit acceptable. Common enablers for intervention delivery included: champion passion for staff health and wellbeing; perceived fit of the program within existing practice; and, management support. Champions and staff reported improvements in knowledge/awareness about sitting, cultural norms, perceived stress, productivity and resilience. Facilitators for sustained change over time included a stable organizational climate and ongoing management support; barriers included workload intensification. The beta version of the BeUpstanding™ Champion Toolkit was highly acceptable to workplace champions and staff, and was perceived to have benefits for team culture and staff knowledge and wellbeing.

Introduction Prevalence of hepatitis C virus (HCV) is substantially higher among prisoners than the general population. In Australia until recently, only a small proportion of prisoners with HCV received antiviral therapy. The direct-acting antivirals (DAAs) for HCV are highly effective, with a low burden of side effects. Since 2016, DAAs are available to all Australians with HCV. However, currently in Australia, they can only be prescribed by or in consultation with experienced prescribers. This study evaluated a telementoring service to upskill doctors and nurse practitioners working in correctional facilities. Methods The telementoring service was implemented in five correctional facilities. Qualitative interviews were used to examine the perceived clinical effectiveness and organisational impacts of the service. Content analysis of the interviews was used to identify key themes. Results In the first ten months of the service, there were 16 telementoring sessions with 173 patients discussed. Sixteen staff participated in qualitative interviews. From these, three key themes were identified: access to antiviral therapy; organisational impacts (cost, increased staff knowledge and confidence, staff time, and workload); and, adaptations of the care model and future opportunities. Conclusion Telementoring is an effective method to facilitate eligible prescriber status to medical doctors and upskill other clinicians in correctional facilities to increase capacity to treat HCV.

BACKGROUND: The Stand Up Victoria multi-component intervention successfully reduced workplace sitting time in both the short (three months) and long (12 months) term. To further understand how this intervention worked, we aimed to assess the impact of the intervention on four social-cognitive constructs, and examined whether these constructs mediated intervention effects on workplace sitting time at 3 and 12 months post-baseline. METHODS: Two hundred and thirty one office-based workers (14 worksites, single government employer) were randomised to intervention or control conditions by worksite. The intervention comprised organisational, environmental, and individual level elements. Participant characteristics and social-cognitive constructs (perceived behavioural control, barrier self-efficacy, perceived organisational norms and knowledge) were measured through a self-administered online survey at baseline, 3 months and 12 months. Workplace sitting time (min/8 h day) was measured with the activPAL3 device. Single multi-level mediation models were performed for each construct at both time points. RESULTS: There were significant intervention effects at 3 months on perceived behavioural control, barrier self-efficacy and perceived organisational norms. Effects on perceived organisational norms were not significant at 12 months. Perceived behavioural control significantly mediated intervention effects at 3 months, accounting for a small portion of the total effect (indirect effect: -8.6 min/8 h day, 95% CI: -18.5, -3.6 min; 7.5% of total effect). At 12 months, barrier self-efficacy significantly mediated the intervention effects on workplace sitting time (indirect effect: -10.3 min/8 h day, 95% CI: -27.3, -2.2; 13.9% of total effect). No significant effects were observed for knowledge at either time point. CONCLUSIONS: Strategies that aim to increase workers' perceived control and self-efficacy over their sitting time may be helpful components of sedentary behaviour interventions in the workplace. However, social-cognitive factors only partially explain variation in workplace sitting reduction. Understanding the importance of other levels of influence (particularly interpersonal and environmental) for initiating and maintaining workplace sedentary behaviour change will be informative for intervention development and refinement. TRIAL REGISTRATION: This study was prospectively registered with the Australian New Zealand Clinical Trials register ( ACTRN12611000742976 ) on 15 July 2011.

BACKGROUND: Sitting, particularly in prolonged, unbroken bouts, is widespread within the office workplace, yet few interventions have addressed this newly-identified health risk behaviour. This paper describes the iterative development process and resulting intervention procedures for the Stand Up Australia research program focusing on a multi-component workplace intervention to reduce sitting time. METHODS: The development of Stand Up Australia followed three phases. 1) Conceptualisation: Stand Up Australia was based on social cognitive theory and social ecological model components. These were operationalised via a taxonomy of intervention strategies and designed to target multiple levels of influence including: organisational structures (e.g. via management consultation), the physical work environment (via provision of height-adjustable workstations), and individual employees (e.g. via face-to-face coaching). 2) Formative research: Intervention components were separately tested for their feasibility and acceptability. 3) Pilot studies: Stand Up Comcare tested the integrated intervention elements in a controlled pilot study examining efficacy, feasibility and acceptability. Stand Up UQ examined the additional value of the organisational- and individual-level components over height-adjustable workstations only in a three-arm controlled trial. In both pilot studies, office workers' sitting time was measured objectively using activPAL3 devices and the intervention was refined based on qualitative feedback from managers and employees. RESULTS: Results and feedback from participants and managers involved in the intervention development phases suggest high efficacy, acceptance, and feasibility of all intervention components. The final version of the Stand Up Australia intervention includes strategies at the organisational (senior management consultation, representatives consultation workshop, team champions, staff information and brainstorming session with information booklet, and supportive emails from managers to staff), environmental (height-adjustable workstations), and individual level (face-to-face coaching session and telephone support). Stand Up Australia is currently being evaluated in the context of a cluster-randomised controlled trial at the Department of Human Services (DHS) in Melbourne, Australia. CONCLUSIONS: Stand Up Australia is an evidence-guided and systematically developed workplace intervention targeting reductions in office workers' sitting time.

BACKGROUND: Desk-based office employees sit for most of their working day. To address excessive sitting as a newly identified health risk, best practice frameworks suggest a multi-component approach. However, these approaches are resource intensive and knowledge about their impact is limited. PURPOSE: To compare the efficacy of a multi-component intervention to reduce workplace sitting time, to a height-adjustable workstations-only intervention, and to a comparison group (usual practice). DESIGN: Three-arm quasi-randomized controlled trial in three separate administrative units of the University of Queensland, Brisbane, Australia. Data were collected between January and June 2012 and analyzed the same year. SETTING/PARTICIPANTS: Desk-based office workers aged 20-65 (multi-component intervention, n=16; workstations-only, n=14; comparison, n=14). INTERVENTION: The multi-component intervention comprised installation of height-adjustable workstations and organizational-level (management consultation, staff education, manager e-mails to staff) and individual-level (face-to-face coaching, telephone support) elements. MAIN OUTCOME MEASURES: Workplace sitting time (minutes/8-hour workday) assessed objectively via activPAL3 devices worn for 7 days at baseline and 3 months (end-of-intervention). RESULTS: At baseline, the mean proportion of workplace sitting time was approximately 77% across all groups (multi-component group 366 minutes/8 hours [SD=49]; workstations-only group 373 minutes/8 hours [SD=36], comparison 365 minutes/8 hours [SD=54]). Following intervention and relative to the comparison group, workplace sitting time in the multi-component group was reduced by 89 minutes/8-hour workday (95% CI=-130, -47 minutes; p<0.001) and 33 minutes in the workstations-only group (95% CI=-74, 7 minutes, p=0.285). CONCLUSIONS: A multi-component intervention was successful in reducing workplace sitting. These findings may have important practical and financial implications for workplaces targeting sitting time reductions.

BACKGROUND: Excessive time spent in sedentary behaviours (sitting or lying with low energy expenditure) is associated with an increased risk for type 2 diabetes, cardiovascular disease and some cancers. Desk-based office workers typically accumulate high amounts of daily sitting time, often in prolonged unbroken bouts. The Stand Up Victoria study aims to determine whether a 3-month multi-component intervention in the office setting reduces workplace sitting, particularly prolonged, unbroken sitting time, and results in improvements in cardio-metabolic biomarkers and work-related outcomes, compared to usual practice. METHODS/DESIGN: A two-arm cluster-randomized controlled trial (RCT), with worksites as the unit of randomization, will be conducted in 16 worksites located in Victoria, Australia. Work units from one organisation (Department of Human Services, Australian Government) will be allocated to either the multi-component intervention (organisational, environmental [height-adjustable workstations], and individual behavioural strategies) or to a usual practice control group. The recruitment target is 160 participants (office-based workers aged 18-65 years and working at least 0.6 full time equivalent) per arm. At each assessment (0- [baseline], 3- [post intervention], and 12-months [follow-up]), objective measurement via the activPAL3 activity monitor will be used to assess workplace: sitting time (primary outcome); prolonged sitting time (sitting time accrued in bouts of ≥30 minutes); standing time; sit-to-stand transitions; and, moving time. Additional outcomes assessed will include: non-workplace activity; cardio-metabolic biomarkers and health indicators (including fasting glucose, lipids and insulin; anthropometric measures; blood pressure; and, musculoskeletal symptoms); and, work-related outcomes (presenteeism, absenteeism, productivity, work performance). Incremental cost-effectiveness and identification of both workplace and individual-level mediators and moderators of change will also be evaluated. DISCUSSION: Stand Up Victoria will be the first cluster-RCT to evaluate the effectiveness of a multi-component intervention aimed at reducing prolonged workplace sitting in office workers. Strengths include the objective measurement of activity and assessment of the intervention on markers of cardio-metabolic health. Health- and work-related benefits, as well as the cost-effectiveness of the intervention, will help to inform future occupational practice. TRIAL REGISTRATION: ACTRN1211000742976.

OBJECTIVE: To investigate the short-term efficacy of a multicomponent intervention to reduce office workers' sitting time. METHODS: Allocation for this non-randomized controlled trial (n=43 participants; 56% women; 26-62 years; Melbourne, Australia) was by office floor, with data collected during July-September 2011. The 4-week intervention emphasized three key messages: "Stand Up, Sit Less, Move More" and comprised organizational, environmental, and individual elements. Changes in minutes/day at the workplace spent sitting (primary outcome), in prolonged sitting (sitting time accumulated in bouts ≥ 30 min), standing, and moving were objectively measured (activPAL3). RESULTS: Relative to the controls, the intervention group significantly reduced workplace sitting time (mean change [95%CI]: -125 [-161, -89] min/8-h workday), with changes primarily driven by a reduction in prolonged sitting time (-73 [-108, -40] min/8-h workday). Workplace sitting was almost exclusively replaced by standing (+127 [+92, +162] min/8-h workday) with non-significant changes to stepping time (-2 [-7, +4] min/8-h workday) and number of steps (-70 [-350, 210]). CONCLUSIONS: This multicomponent workplace intervention demonstrated that substantial reductions in sitting time are achievable in an office setting. Larger studies with longer timeframes are needed to assess sustainability of these changes, as well as their potential longer-term impacts on health and work-related outcomes.

BACKGROUND: Increasing adults' physical activity through environmental initiatives that promote walking as a public health priority. To this end, evidence relevant to the urban planning and transport sectors is required. This review synthesized findings on destination and route attributes associated with utilitarian and recreational walking. METHODS: A literature search was conducted in April 2011 using Web of Science, PubMed, Transport Research Information Services, GEOBASE, and SPORTDiscus. Environmental attributes were classified into the domains of utilitarian and recreational destinations (presence, proximity, quality) and route (sidewalks, connectivity, aesthetics, traffic, safety). Forty-six studies examining associations of these attributes with utilitarian and/or recreational walking were identified. Specific destination and route attributes associated with each type of walking were summarized. RESULTS: Adults' utilitarian walking was consistently associated with presence and proximity of retail and service destinations (in 80% of the studies reviewed). It was also associated with functional aspects of routes (sidewalks and street connectivity) in 50% of studies. Recreational walking was associated with presence, proximity, and quality of recreational destinations (35% of studies) and route aesthetic (35% of studies). Both types of walking were found unrelated to route safety and traffic in most studies. CONCLUSIONS: There is consistent evidence that better access to relevant neighborhood destinations (e.g., local stores, services, transit stops) can be conducive to adults' utilitarian walking. Some evidence also suggests that availability of sidewalks and well-connected streets can facilitate utilitarian walking. To better inform initiatives to promote adults' walking in the planning and transport sectors, future studies need to examine how accessible such destinations should be, as well as the effect of the quality of recreational destinations.

CONTEXT: To systematically review and provide an informative synthesis of findings from longitudinal studies published since 1996 reporting on relationships between self-reported sedentary behavior and device-based measures of sedentary time with health-related outcomes in adults. EVIDENCE ACQUISITION: Studies published between 1996 and January 2011 were identified by examining existing literature reviews and by systematic searches in Web of Science, MEDLINE, PubMed, and PsycINFO. English-written articles were selected according to study design, targeted behavior, and health outcome. EVIDENCE SYNTHESIS: Forty-eight articles met the inclusion criteria; of these, 46 incorporated self-reported measures including total sitting time; TV viewing time only; TV viewing time and other screen-time behaviors; and TV viewing time plus other sedentary behaviors. Findings indicate a consistent relationship of self-reported sedentary behavior with mortality and with weight gain from childhood to the adult years. However, findings were mixed for associations with disease incidence, weight gain during adulthood, and cardiometabolic risk. Of the three studies that used device-based measures of sedentary time, one showed that markers of obesity predicted sedentary time, whereas inconclusive findings have been observed for markers of insulin resistance. CONCLUSIONS: There is a growing body of evidence that sedentary behavior may be a distinct risk factor, independent of physical activity, for multiple adverse health outcomes in adults. Prospective studies using device-based measures are required to provide a clearer understanding of the impact of sedentary time on health outcomes.

OBJECTIVE: In the past decade, there has been no systematic review of the evidence for maintenance of physical activity and/or dietary behavior change following intervention (follow-up). This systematic review addressed three questions: 1) How frequently do trials report on maintenance of behavior change? 2) How frequently do interventions achieve maintenance of behavior change? 3) What sample, methodologic, or intervention characteristics are common to trials achieving maintenance? DESIGN: Systematic review of trials that evaluated a physical activity and/or dietary behavior change intervention among adults, with measurement at preintervention, postintervention, and at least 3 months following intervention completion (follow-up). MAIN OUTCOME MEASURES: Maintenance of behavior change was defined as a significant between-groups difference at postintervention and at follow-up, for one or more physical activity and/or dietary outcome. RESULTS: Maintenance outcomes were reported in 35% of the 157 intervention trials initially considered for review. Of the 29 trials that met all inclusion criteria, 21 (72%) achieved maintenance. Characteristics common to trials achieving maintenance included those related to sample characteristics (targeting women), study methods (higher attrition and pretrial behavioral screening), and intervention characteristics (longer duration [>24 weeks], face-to-face contact, use of more intervention strategies [>6], and use of follow-up prompts). CONCLUSIONS: Maintenance of physical activity and dietary behavior change is not often reported; when it is, it is often achieved. To advance the evidence, the field needs consensus on reporting of maintenance outcomes, controlled evaluations of intervention strategies to promote maintenance, and more detailed reporting of interventions.
