Does evidence support the use of mobile phone apps as a driver for promoting healthy lifestyles from a public health perspective? A systematic review of Randomized Control Trials

ObjectiveThe aim of this systematic review was to find a scientific evidence on the efficacy of apps in promoting healthy lifestyles.MethodsThe research was carried out according to PRISMA Statement. Pubmed, Embase and Google Scholar searches were carried out up to September 2016 focusing on randomized control trials (RCTs).ResultsForty RCTs were selected. Most of the studies targeted weight management, PA and healthy eating (N = 35). A few RCTs focused on apps designed to sun protection, smoking cessation and alcohol consumption (N = 5). Only 10 RCTs (25%) found statistical difference between intervention and control groups for all the outcomes measured. Most of the studies had a short follow-up (65%, less than 6 months) and half of them a very small sample size (fewer than 100 subjects).ConclusionOverall, the evidence so far showed a modest efficacy of apps in health promotion.Practice implicationsThere is a need to improve the overall quality of intervention studies focused on mobile apps in order to understand if they could became a valuable tool in support of health professionals and their efforts to promote education and health.     

Web-Assisted Tobacco Interventions: Empowering Change in the Global Fight for the Public’s (e)Health

Tobacco control in the 21^st century faces many of the same challenges as in the past, but in different contexts, settings and enabled by powerful new tools including those delivered by information and communication technologies via computer, videocasts, and mobile handsets to the world. Building on the power of electronic networks, Web-assisted tobacco interventions (WATI) provide a vehicle for delivering tobacco prevention, cessation, social support and training opportunities on-demand and direct to practitioners and the public alike. The Framework Convention on Tobacco Control, the world’s first global public health treaty, requires that all nations develop comprehensive tobacco control strategies that include provision of health promotion information, population interventions, and decision-support services. WATI research and development has evolved to provide examples of how eHealth can address all of these needs and provide exemplars for other areas of public health to follow. This paper discusses the role of WATI in supporting tobacco control and introduces a special issue of the Journal of Medical Internet Research that broadens the evidence base and provides illustrations of how new technologies can support health promotion and population health overall, empowering change and ushering in a new era of public eHealth.     

The Role of Social Network Technologies in Online Health Promotion: A Narrative Review of Theoretical and Empirical Factors Influencing Intervention Effectiveness

Background

Social network technologies have become part of health education and wider health promotion—either by design or happenstance. Social support, peer pressure, and information sharing in online communities may affect health behaviors. If there are positive and sustained effects, then social network technologies could increase the effectiveness and efficiency of many public health campaigns. Social media alone, however, may be insufficient to promote health. Furthermore, there may be unintended and potentially harmful consequences of inaccurate or misleading health information. Given these uncertainties, there is a need to understand and synthesize the evidence base for the use of online social networking as part of health promoting interventions to inform future research and practice.

Objective

Our aim was to review the research on the integration of expert-led health promotion interventions with online social networking in order to determine the extent to which the complementary benefits of each are understood and used. We asked, in particular, (1) How is effectiveness being measured and what are the specific problems in effecting health behavior change?, and (2) To what extent is the designated role of social networking grounded in theory?

Methods

The narrative synthesis approach to literature review was used to analyze the existing evidence. We searched the indexed scientific literature using keywords associated with health promotion and social networking. The papers included were only those making substantial study of both social networking and health promotion—either reporting the results of the intervention or detailing evidence-based plans. General papers about social networking and health were not included.

Results

The search identified 162 potentially relevant documents after review of titles and abstracts. Of these, 42 satisfied the inclusion criteria after full-text review. Six studies described randomized controlled trials (RCTs) evaluating the effectiveness of online social networking within health promotion interventions. Most of the trials investigated the value of a “social networking condition” in general and did not identify specific features that might play a role in effectiveness. Issues about the usability and level of uptake of interventions were more common among pilot studies, while observational studies showed positive evidence about the role of social support. A total of 20 papers showed the use of theory in the design of interventions, but authors evaluated effectiveness in only 10 papers.

Conclusions

More research is needed in this area to understand the actual effect of social network technologies on health promotion. More RCTs of greater length need to be conducted taking into account contextual factors such as patient characteristics and types of a social network technology. Also, more evidence is needed regarding the actual usability of online social networking and how different interface design elements may help or hinder behavior change and engagement. Moreover, it is crucial to investigate further the effect of theory on the effectiveness of this type of technology for health promotion. Research is needed linking theoretical grounding with observation and analysis of health promotion in online networks.     

Otitis media among high-risk populations: can probiotics inhibit Streptococcus pneumoniae colonisation and the risk of disease?

Otitis media is the second most common infection in children and the leading cause for seeking medical advice. Indigenous populations such as the Inuits, indigenous Australians and American Indians have a very high prevalence of otitis media and are considered to be high-risk populations. Streptococcus pneumoniae, one of the three main bacterial causes of otitis media, colonises the nasopharynx prior to disease development. In high-risk populations, early acquisition of high bacterial loads increases the prevalence of otitis media. In these settings, current treatment strategies are insufficient. Vaccination is effective against invasive pneumococcal infection but has a limited impact on otitis media. Decreasing the bacterial loads of otitis media pathogens and/or colonising the nasopharynx with beneficial bacteria may reduce the prevalence of otitis media. Probiotics are live microorganisms that offer health benefits by modulating the microbial community and enhancing host immunity. The available data suggest that probiotics may be beneficial in otitis media. This review discusses the potential use of probiotics to reduce pathogen colonisation and decrease the prevalence of otitis media, providing justification for further investigation.     

Cervical cancer in Indigenous women: The case of Australia

Globally, health inequities between Indigenous and non-Indigenous populations exist. The disparity in health outcomes between Indigenous and non-Indigenous Australians is exemplified by cervical cancer. Current evidence suggests that Indigenous women have higher age standardised incidence and mortality than non-Indigenous women when adjusted for stage at diagnosis and co-morbidities; however, there is little information pertaining to national estimates of cervical cancer in Indigenous women. In this paper we review available evidence on the difference in occurrence and case fatality of cervical cancer among Indigenous and non-Indigenous Australian women.The Australian Bureau of Statistics, Australian Institute of Health and Welfare, and State- or Territory-based Cancer Registries were utilised to collect surveillance data. To corroborate existing data, further available journal literature was identified through Medline and Embase. All papers selected for review were cross-referenced to identify further relevant studies.The most recent national estimate of age-standardised cervical cancer incidence rate was 16.9 and 7.1 per 100,000 women-years in Indigenous and non-Indigenous women respectively (incidence ratio 2.4). The Indigenous age-standardised mortality rate was 9.9 per 100,000 women years (95% CI 7.1–13.3), over 5 times the non-Indigenous rate. Cervical cancer incidence, in both Indigenous and non-Indigenous women, has decreased since 1991. Despite the decline, age-standardised incidence among Indigenous women is still higher than non-Indigenous women.The pattern of cervical cancer incidence and survival corroborates the health inequities that exist in Australia. Indigenous women are more likely than non-Indigenous women to develop cervical cancer and are less likely to survive it. Similar patterns exist in Indigenous populations worldwide, such as New Zealander Maoris and Canadian Aboriginals, suggesting that high rates of cervical cancer incidence and mortality may be a symptom of social and economic inequity.     

Acceptability of Mental Health Apps for Aboriginal and Torres Strait Islander Australians: A Qualitative Study

BackgroundAboriginal and Torres Strait Islander Australians experience high rates of mental illness and psychological distress compared to their non-Indigenous counterparts. E-mental health tools offer an opportunity for accessible, effective, and acceptable treatment. The AIMhi Stay Strong app and the ibobbly suicide prevention app are treatment tools designed to combat the disproportionately high levels of mental illness and stress experienced within the Aboriginal and Torres Strait Islander community.ObjectiveThis study aimed to explore Aboriginal and Torres Strait Islander community members’ experiences of using two culturally responsive e-mental health apps and identify factors that influence the acceptability of these approaches.MethodsUsing qualitative methods aligned with a phenomenological approach, we explored the acceptability of two culturally responsive e-mental health apps through a series of three 3-hour focus groups with nine Aboriginal and Torres Strait Islander community members. Thematic analysis was conducted and coresearcher and member checking were used to verify findings.ResultsFindings suggest strong support for the concept of e-mental health apps and optimism for their potential. Factors that influenced acceptability related to three key themes: personal factors (eg, motivation, severity and awareness of illness, technological competence, and literacy and language differences), environmental factors (eg, community awareness, stigma, and availability of support), and app characteristics (eg, ease of use, content, graphics, access, and security and information sharing). Specific adaptations, such as local production, culturally relevant content and graphics, a purposeful journey, clear navigation, meaningful language, options to assist people with language differences, offline use, and password protection may aid uptake.ConclusionsWhen designed to meet the needs of Aboriginal and Torres Strait Islander Australians, e-mental health tools add an important element to public health approaches for improving the well-being of Aboriginal and Torres Strait Islander people.     

Facebook Apps for Smoking Cessation: A Review of Content and Adherence to Evidence-Based Guidelines

Background

Facebook is the most popular social network site, with over 1 billion users globally. There are millions of apps available within Facebook, many of which address health and health behavior change. Facebook may represent a promising channel to reach smokers with cessation interventions via apps. To date, there have been no published reports about Facebook apps for smoking cessation.

Objective

The purpose of this study was to review the features and functionality of Facebook apps for smoking cessation and to determine the extent to which they adhere to evidence-based guidelines for tobacco dependence treatment.

Methods

In August 2013, we searched Facebook and three top Internet search engines using smoking cessation keywords to identify relevant Facebook apps. Resultant apps were screened for eligibility (smoking cessation-related, English language, and functioning). Eligible apps were reviewed by 2 independent coders using a standardized coding scheme. Coding included content features (interactive, informational, and social) and adherence to an established 20-item index (possible score 0-40) derived from the US Public Health Service’s Clinical Practice Guidelines for Treating Tobacco Use and Dependence.

Results

We screened 22 apps for eligibility; of these, 12 underwent full coding. Only 9 apps were available on Facebook. Facebook apps fell into three broad categories: public pledge to quit (n=3), quit-date–based calculator/tracker (n=4), or a multicomponent quit smoking program (n=2). All apps incorporated interactive, informational, and social features except for two quit-date–based calculator/trackers apps (lacked informational component). All apps allowed app-related posting within Facebook (ie, on self/other Facebook profile), and four had a within-app “community” feature to enable app users to communicate with each other. Adherence index summary scores among Facebook apps were low overall (mean 15.1, SD 7.8, range 7-30), with multicomponent apps scoring the highest.

Conclusions

There are few smoking cessation apps available within Facebook. Among those available, adherence to cessation treatment guidelines was low. Smoking cessation interventions provided via the Facebook platform are a unique and as yet untapped treatment strategy that can harness existing social support and social networks for quitting. Research is needed to examine whether apps that adhere to clinical practice guidelines for tobacco dependence treatment are more effective in promoting cessation than those that do not.     

Prevalence and Frequency of mHealth and eHealth Use Among US and UK Smokers and Differences by Motivation to Quit

BackgroundBoth mHealth and eHealth interventions for smoking cessation are rapidly being developed and tested. There are no data on use of mHealth and eHealth technologies by smokers in general or by smokers who are not motivated to quit smoking.ObjectiveThe aims of our study were to (1) assess technology use (eg, texting, social media, Internet) among smokers in the United States and United Kingdom, (2) examine whether technology use differs between smokers who are motivated to quit and smokers who are not motivated to quit, (3) examine previous use of technology to assist with smoking cessation, and (4) examine future intentions to use technology to assist with smoking cessation.MethodsParticipants were 1000 adult smokers (54.90%, 549/1000 female; mean age 43.9, SD 15.5 years; US: n=500, UK: n=500) who were recruited via online representative sampling strategies. Data were collected online and included demographics, smoking history, and frequency and patterns of technology use.ResultsAmong smokers in general, there was a high prevalence of mobile and smartphone ownership, sending and receiving texts, downloading and using apps, using Facebook, and visiting health-related websites. Smokers who were unmotivated to quit were significantly less likely to own a smartphone or handheld device that connects to the Internet than smokers motivated to quit. There was a significantly lower prevalence of sending text messages among US smokers unmotivated to quit (78.2%, 179/229) versus smokers motivated to quit (95.0%, 229/241), but no significant differences between the UK groups (motivated: 96.4%, 239/248; unmotivated: 94.9%, 223/235). Smokers unmotivated to quit in both countries were significantly less likely to use a handheld device to read email, play games, browse the Web, or visit health-related websites versus smokers motivated to quit. US smokers had a high prevalence of app downloads regardless of motivation to quit, but UK smokers who were motivated to quit had greater prevalence of app downloads than smokers unmotivated to quit. US smokers were significantly more likely to have a Facebook account (87.0%, 435/500) than UK smokers (76.4%, 382/500), but smokers unmotivated to quit in both countries used Facebook less frequently than smokers motivated to quit. Smokers who were unmotivated to quit were less likely to have used eHealth or mHealth platforms to help them quit smoking in the past and less likely to say that they would use them for smoking cessation in the future.ConclusionsAlthough smokers unmotivated to quit make less use of technology than smokers motivated to quit, there is sufficient prevalence to make it worthwhile to develop eHealth and mHealth interventions to encourage cessation. Short and low-effort communications, such as text messaging, might be better for smokers who are less motivated to quit. Multiple channels may be required to reach unmotivated smokers.     

Motivational interviewing to promote interconception health: A scoping review of evidence from clinical trials

BackgroundPromoting interconception health can improve birth outcomes and long-term women’s health. Motivational Interviewing (MI) is an evidence-based behavior change strategy that can address interconception health behaviors and health care engagement.ObjectiveThis scoping review assessed the evidence for using MI to promote interconception health and assessed features of successful MI interventions.MethodsWe searched PubMed, CHINAL, and Cochrane databases for clinical trials that involved an MI intervention and at least one comparison group published by 8/31/2021. Interventions occurred during pregnancy or within three months postpartum and outcomes were measured between birth and one year postpartum. We abstracted data on trial characteristics including outcome, population, interventionist training, MI fidelity monitoring, intervention dose, and comparison condition. We examined whether trials that demonstrated statistically significant improvement in outcomes had common features.ResultsThere were 37 included studies. Interventions addressed breastfeeding, teen contraception, tobacco, alcohol, or substance use, vaccine acceptance, nutrition, physical activity, and depression. No trials addressed more than one topic. Nineteen studies demonstrated improved outcomes. Interventions during the perinatal or postnatal periods were more likely to demonstrate improved interconception outcomes than interventions in the prenatal period. No other trial characteristics were consistently associated with demonstrating improved outcomes.DiscussionMI has been applied to a variety of interconception health behaviors, with some promising results, particularly for interventions in the perinatal or postpartum period. Outcomes were not clearly attributable to any other differences in intervention or study design. Further exploring context or implementation may help maximize the potential of MI in interconception health promotion.Practical valueMI may be implemented across a range of clinical settings, patient groups, and time points around pregnancy. Interventions on health topics relevant to the interconception period should incorporate perinatal or postpartum components.     

Digital health interventions in children with asthma

Although healthcare providers are actively involved in offering education, information and interventions for asthmatic patients, medication and therapeutic adherence remain low in the paediatric population, with estimates suggesting that adherence rates hover below 50%. A range of available digital health interventions has been explored in paediatric asthma with promising but variable results, limiting their widespread adoption in clinical practice. They include emerging technologies that yield the advantage of tracking asthma symptoms and medications, setting drug reminders, improving inhaler technique and delivering asthma education, such as serious games (video games designed for medical- or health-related purposes), electronic monitoring devices, speech recognition calls, text messaging, mobile apps and interactive websites. Some of the proposed digital interventions have used multiple components, including educational and behavioural strategies and interactions with medical professionals. Overall, the implementation of such interventions may offer the opportunity to improve adherence and asthma control. In a state of emergency as the COVID-19 pandemic, telemedicine can also play a central role in supporting physicians in managing children with asthma. This review evaluates the published literature examining digital health interventions for paediatric asthma and explores the most relevant issues affecting their implementation in practice and the associated evidence gaps, research limitations and future research perspectives.     

Combining mHealth and health-coaching for improving self-management in chronic care. A scoping review

BackgroundSelf-management approaches are widely used to improve chronic care. In this context, health care professionals call for efficient tools to engage patients in managing their illness. Mobile health (mHealth), defined by WHO as medical and public health practice supported by mobile devices, is demonstrated to enhance self-management and health-coaching as an engaging tool in supporting behaviour change. Nevertheless, it is unclear how health-coaching and mHealth can benefit from each other.ObjectiveWe conducted a scoping review to provide a literature-overview and identify any existing gaps in knowledge of mHealth in combination with health-coaching interventions for improving self-management in patients with chronic diseases.Patient involvementNo patients were involved in the review process.MethodsThe five-stage framework by Arksey and O'Malley was used. The review surveys; PubMed, CINAHL, Embase, Scopus, and PsycInfo. Two independent reviewers performed review selection and characterization.ResultsThe review points at two approaches; (i) coaching used to support mHealth and (ii) mHealth as support for coaching. The findings suggest that patients prefer physical interactions to telecommunication. mHealth was primarily used to facilitate telecommunication and to monitor disease aspects.DiscussionWe found that mHealth and health-coaching interventions benefit from each other. The review report on a considerable unclarity in the coaching-methods and that the patients were more satisfied with physical interactions than mHealth. We suggest to prioritize human contact and to explore more personalized health technology.Practical valueThis scoping review can provide a framework for researchers and care providers to support discussion and introduction of new approaches and technology in self-management for patients with chronic diseases, thereby improving patients’ quality of life.     

Factors shaping the provision of sexual health education for adults with acute coronary syndrome: A scoping review

ObjectiveEach year, 63,000 Canadians are diagnosed with acute coronary syndrome (ACS)and 73 % survive. Sexual health education for ACS survivors is recommended but is not routinely provided. A scoping review was performed to inform health care providers about factors shaping sexual health education for ACS survivors.MethodsThree databases were searched, 208 studies were screened, and 24 were included in this scoping review. Significant points from the selected studies were charted and synthesized.ResultsThis review confirmed absent to limited provision of sexual health education to individuals with ACS. Key factors influencing lack of provision of sexual health were categorized according to macro, meso, and micro levels. At the macro level, societal and cultural factors were noted. The meso level included healthcare environment and limited healthcare provider knowledge. At the micro level, healthcare professional-healthcare consumer relationships and role clarity were noted.ConclusionA sex positive approach may facilitate provision of sexual health education.Practice implicationsThis scoping review points to the need to use a sex positive lens to identify and remove barriers to facilitate the provision of sexual health education. Providing this education may result in reduced fear, depression, and anxiety in ACS survivors.     

Public health interventions: reaching Latino adolescents via short message service and social media

Background

Adolescents are substantial users of short message service (SMS) and social media. The public health community now has more opportunities to reach this population with positive youth development and health messages through these media. Latinos are a growing and youthful population with significant health risks and needs. This population may benefit from SMS and social media health interventions.

Objective

To examine (1) SMS and social media utilization and behavior among Latino youth, and (2) how SMS and social media can be effectively used as a component of public health interventions focused on decreasing sexual risk taking among Latino youth.

Methods

A mixed-methods approach, using both quantitative survey data and qualitative interview data, was used to provide a robust understanding of SMS and social media use and behavior for public health interventions. We recruited 428 ninth and tenth grade, self-identifying Latino adolescents to participate in a quantitative survey. Additionally, we conducted five key informant interviews with staff and 15 youth.

Results

We found that 90.8% (355/391) of respondents had access to a mobile phone either through having their own or through borrowing or sharing one. Of those who had access to a mobile phone, 94.1% (334/355) used SMS, with 41.1% (113/275) sending and receiving more than 100 text messages per day. Of 395 respondents, 384 (97.2%) had at least one social media account, and the mean number of accounts was 3.0 (range 0–8). A total of 75.8% (291/384) of adolescents logged in to their account daily. Of those with a social media account, 89.1% (342/384) had a Facebook account. Youth who took the survey in English were significantly more likely than those who took it in Spanish to have access to a mobile phone (χ² ₁ = 5.3; 93.3% vs 86.3%; P = .02); to be high-volume texters (χ² ₂ = 16.8; 49.4% vs 25.3%; P < .001); to use the Internet daily (χ² ₁ = 5.0; 76.6% vs 66.0%; P = .03); to have a Facebook account (χ² ₁ = 9.9; 90.9% vs 79.7%; P = .002); and to have a greater mean number of social media accounts (t ₃₈₇ = 7.9; 3.41 vs 2.07; P < .001).

Conclusions

SMS and social media are pervasive among Latino youth. Program staff and youth perceive these as credible and essential methods of communication in the context of public health programs. Public health interventions must continue to innovate and maximize new ways to reach young people to reinforce public health messages and education.     

Exploring Indigenous Traditional Healing programs in Canada,Australia, and New Zealand: A scoping review

ObjectiveTo explore and catalog ways Indigenous Traditional Healing practices are supported within the mainstream healthcare system through policies and programs in Canada, Australia, and New Zealand.Data SourcesA scoping review was conducted, guided by the PRISMA extension for Scoping Reviews. Databases for sources of information include CINAHL, Medline, Embase, Web of Science, Public Health ProQuest, Global Health EBSCO, iPortal, and grey literature.Study Selection2 reviewers screened the titles and abstracts of the studies for inclusion against the selection criteria independently. Studies that met the inclusion criteria were transferred to Covidence for further abstract and full-text review.Data ExtractionOf a total of 2,017 articles identified, 22 met the inclusion criteria for data extraction for this scoping review. Data items extracted include study title, authors, year of publication, publication type, publication source, support policy or program, health system or service, Indigenous Traditional Healing practices, and significant findings.Data Synthesis2 categories emerged from the analysis of the source of evidence. That is, healthcare systems and services with programs and policies supporting Indigenous Traditional Healing practices, and ways Indigenous Traditional Healing was adopted and utilized within the identified support programs.ConclusionsThis study demonstrated the various ways Indigenous Traditional Healing practices are supported within the mainstream healthcare systems in Canada, Australia, and New Zealand. Indigenous Traditional Healing practices can be utilized as either the primary choice of treatment, to support Western biomedical treatment or through the adoption of Indigenous Traditional knowledge within the mainstream healthcare system.     

“Friending” Teens: Systematic Review of Social Media in Adolescent and Young Adult Health Care

Background

Social media has emerged as a potentially powerful medium for communication with adolescents and young adults around their health choices.

Objective

The goal of this systematic review is to identify research on the use of social media for interacting with adolescents and young adults in order to achieve positive health outcomes.

Methods

A MEDLINE/PubMed electronic database search was performed between January 1, 2002 and October 1, 2013, using terms to identify peer-reviewed research in which social media and other Web 2.0 technologies were an important feature. We used a systematic approach to retrieve papers and extract relevant data.

Results

We identified 288 studies involving social media, of which 87 met criteria for inclusion; 75 studies were purely observational and 12 were interventional. The ways in which social media was leveraged by these studies included (1) observing adolescent and young adult behavior (n=77), (2) providing health information (n=13), (3) engaging the adolescent and young adult community (n=17), and (4) recruiting research participants (n=23). Common health topics addressed included high-risk sexual behaviors (n=23), alcohol, tobacco, and other drug use (n=19), Internet safety (n=8), mental health issues (n=18), medical conditions (n=11), or other specified issues (n=12). Several studies used more than one social media platform and addressed more than one health-related topic.

Conclusions

Social media technologies offer an exciting new means for engaging and communicating with adolescents and young adults; it has been successfully used to engage this age group, identify behaviors, and provide appropriate intervention and education. Nevertheless, the majority of studies to date have been preliminary and limited in their methodologies, and mostly center around evaluating how adolescents and young adults use social media and the resulting implications on their health. Although these explorations are essential, further exploration and development of these strategies into building effective interventions is necessary.     

Smartphones for Smarter Delivery of Mental Health Programs: A Systematic Review

Background

The rapid growth in the use of mobile phone applications (apps) provides the opportunity to increase access to evidence-based mental health care.

Objective

Our goal was to systematically review the research evidence supporting the efficacy of mental health apps for mobile devices (such as smartphones and tablets) for all ages.

Methods

A comprehensive literature search (2008-2013) in MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, PsycINFO, PsycTESTS, Compendex, and Inspec was conducted. We included trials that examined the effects of mental health apps (for depression, anxiety, substance use, sleep disturbances, suicidal behavior, self-harm, psychotic disorders, eating disorders, stress, and gambling) delivered on mobile devices with a pre- to posttest design or compared with a control group. The control group could consist of wait list, treatment-as-usual, or another recognized treatment.

Results

In total, 5464 abstracts were identified. Of those, 8 papers describing 5 apps targeting depression, anxiety, and substance abuse met the inclusion criteria. Four apps provided support from a mental health professional. Results showed significant reductions in depression, stress, and substance use. Within-group and between-group intention-to-treat effect sizes ranged from 0.29-2.28 and 0.01-0.48 at posttest and follow-up, respectively.

Conclusions

Mental health apps have the potential to be effective and may significantly improve treatment accessibility. However, the majority of apps that are currently available lack scientific evidence about their efficacy. The public needs to be educated on how to identify the few evidence-based mental health apps available in the public domain to date. Further rigorous research is required to develop and test evidence-based programs. Given the small number of studies and participants included in this review, the high risk of bias, and unknown efficacy of long-term follow-up, current findings should be interpreted with caution, pending replication. Two of the 5 evidence-based mental health apps are currently commercially available in app stores.     

Understanding Online Health Groups for Depression: Social Network and Linguistic Perspectives

BackgroundMental health problems have become increasingly prevalent in the past decade. With the advance of Web 2.0 technologies, social media present a novel platform for Web users to form online health groups. Members of online health groups discuss health-related issues and mutually help one another by anonymously revealing their mental conditions, sharing personal experiences, exchanging health information, and providing suggestions and support. The conversations in online health groups contain valuable information to facilitate the understanding of their mutual help behaviors and their mental health problems.ObjectiveWe aimed to characterize the conversations in a major online health group for major depressive disorder (MDD) patients in a popular Chinese social media platform. In particular, we intended to explain how Web users discuss depression-related issues from the perspective of the social networks and linguistic patterns revealed by the members’ conversations.MethodsSocial network analysis and linguistic analysis were employed to characterize the social structure and linguistic patterns, respectively. Furthermore, we integrated both perspectives to exploit the hidden relations between them.ResultsWe found an intensive use of self-focus words and negative affect words. In general, group members used a higher proportion of negative affect words than positive affect words. The social network of the MDD group for depression possessed small-world and scale-free properties, with a much higher reciprocity ratio and clustering coefficient value as compared to the networks of other social media platforms and classic network models. We observed a number of interesting relationships, either strong correlations or convergent trends, between the topological properties and linguistic properties of the MDD group members.Conclusions(1) The MDD group members have the characteristics of self-preoccupation and negative thought content, according to Beck’s cognitive theory of depression; (2) the social structure of the MDD group is much stickier than those of other social media groups, indicating the tendency of mutual communications and efficient spread of information in the MDD group; and (3) the linguistic patterns of MDD members are associated with their topological positions in the social network.     

The impact of post-adoption beliefs on the continued use of health apps

BackgroundRecently, there has been a rapid increase in the development and use of health apps on smartphones. In spite of research on such technologies, there exist considerable gaps between health app use and our understandings of such technology. Therefore, this study explored the process of leading people to keep using health apps, mainly based on the post-acceptance model (PAM).PurposeDespite significant previous research on health apps, few studies have focused on the post-adoption behaviors of using these technologies. To address and fill the gaps in health app research, this study has developed and tested a model to explain the micro-mechanism that determines the continuance intention to use health apps, theoretically relying on the post-acceptance model (PAM) and the technology acceptance model (TAM).MethodsA sample consisting of 343 Korean adults who were currently using health apps on smartphones participated in an online survey. A path analysis was conducted to test the proposed model composed of the main factors from PAM and TAM.ResultsThe results from the path analysis indicated that the following perceptual and emotional factors—perceived usefulness, perceived ease of use, confirmation, and satisfaction—were significantly associated with the continuance intention to use health apps on smartphones.Discussion/ConclusionMain findings from this present study contribute to developing and empirically testing a model of explaining the basic process of motivating health app users to keep using those apps. This model will be helpful for researchers to further examine health-related technologies, particularly mHealth-oriented ones.
