Automated Mobile Phone-Based Mental Health Resource for Homeless Youth: Pilot Study Assessing Feasibility and Acceptability

A collaborative realist review of remote measurement technologies for depression in young people

Digital mental health is becoming increasingly common. This includes use of smartphones and wearables to collect data in real time during day-to-day life (remote measurement technologies, RMT). Such data could capture changes relevant to depression for use in objective screening, symptom management and relapse prevention. This approach may be particularly accessible to young people of today as the smartphone generation. However, there is limited research on how such a complex intervention would work in the real world. We conducted a collaborative realist review of RMT for depression in young people. Here we describe how, why, for whom and in what contexts RMT appear to work or not work for depression in young people and make recommendations for future research and practice. Ethical, data protection and methodological issues need to be resolved and standardized; without this, RMT may be currently best used for self-monitoring and feedback to the healthcare professional where possible, to increase emotional self-awareness, enhance the therapeutic relationship and monitor the effectiveness of other interventions.

Cancer care and treatment during homelessness

People experiencing homelessness have not yet benefited from the substantial progress made in managing cancers, including advances in chemotherapy and radiotherapy, surgical interventions, multidisciplinary team approaches, and integrated cancer care models. People experiencing homelessness are at higher risks of developing cancers and their mortality due to cancer is twice that of the general population. Potential interventions to improve access to cancer treatment include alliances and active engagement with community organisations and shelters, cancer case management and peer-to-peer support, mHealth and navigation strategies, tailored hospital discharge to adult group homes, well equipped subacute rehabilitation centres, and specialised shelters and respite housing to assure appropriate follow-up care. Other interventions include improving preventive care, expanding data, targeted policy efforts, and broader housing advocacy. In this Personal View, I discuss challenges and opportunities in cancer treatment, with a review of the current evidence on potential interventions, and highlight strategies to improve access to cancer care for homeless populations.

SMS text intervention for uncontrolled hypertension among hypertensive homeless adults in shelter clinics of New York City: protocol for a pragmatic randomised trial study

INTRODUCTION

Uncontrolled hypertension (HTN) is prevalent in persons experiencing homelessness (PEH) and contributes to significant suffering and financial cost. Mobile health approaches such as short messaging service (SMS) texting have led to better control of HTN in the general population. Despite the high utilisation of mobile phones by PEH, SMS texting to support HTN control has not been evaluated among this population. We hypothesise that an SMS testing programme will enhance health communication, information management, outreach and care coordination, and provide behavioural support to address some barriers to HTN management in PEH.

METHODS AND ANALYSIS

This study will use a mixed-methods study design to address two objectives: First, it will evaluate, in a randomised controlled trial, the efficacy of a 6-month SMS texting strategy vs an attention control on blood pressure reduction and adherence to medications and clinical appointments in 120 adults PEH with uncontrolled HTN. Outcomes will be measured at 0, 2, 4 and 6 months. Second, it will assess patients' and providers' acceptability and experience of SMS texting using semistructured interviews with PEH (n=30) and providers (n=10). The study will be conducted in shelter clinics in New York City in collaboration with community organisations. The primary statistical analysis will be on an intention-to-treat basis. The trial results will be reported as comparative summary statistics (difference in response rate or means) with 95% CIs and in accordance with the Consolidated Standards of Reporting Trials (CONSORT). Interviews will be transcribed, coded and analysed using an inductive grounded theory analysis.

ETHICS AND DISSEMINATION

This study has been approved by the Institutional Review Board (IRB) at George Washington University. Written consent will be obtained from participants. The findings will be disseminated in peer-reviewed journals.

Attending to the Mental Health of People Who Are Homeless by Mobile Telephone Follow-Up: A Systematic Review

BACKGROUND

More than 20% of the world's population has no decent or suitable home. People who are homeless have more health problems than the rest of the population, especially mental health-type problems. The main objective of this study was to identify follow-up interventions by using mobile telephones to improve the mental health of people who are homeless and to analyze their efficiency.

METHODS

To do so, a systematic review was carried out in the Web of Science, PubMed, Scopus, Ebscohost, and PsyInfo databases.

RESULTS

Studies conclude that mobile phone use is a suitable means to improve adherence to medication and the mental health of the homeless. However, significant attempts to demonstrate health benefits by means of reliable and valid instruments that supplement qualitative satisfaction and feedback instruments appear to be lacking.

CONCLUSIONS

The literature about mental health benefits through technology for people who are homeless is scarce and shows methodological limitations that can lead to failure when setting up methodologies in clinical practice.

Of not passing: homelessness, addiction, mental health and care during COVID-19

People experiencing homelessness in the UK were unconditionally offered housing (and support) from the beginning of the first lockdown in March 2020. For many, that meant '(re)entering' the support system and having a chance to 'move on' to longer-term housing. This beneficial effect of some of the policy reactions to the pandemic on people experiencing homelessness was unexpected. On the flip side, however, particularly for people struggling with drug use and mental health issues, adequate support was not available for long periods of time; support was either suspended temporarily or people were excluded from institutional support for not adhering to, for instance, lockdown rules. Similarly, digital support alternatives-modelled on increasingly widespread telemedicine-did often not work specifically for people struggling with complex needs or women experiencing homelessness. This research paper reports detailed evidence of what we observed as continued and catalysed exclusions based on interviews and ethnographic observations with both people experiencing homelessness and service providers from the beginning of the COVID-19 pandemic. Referring to our insights and learnings from three locally and temporally overlapping research projects between May 2020 and April 2021, we also propose changes to redesign future (health)care provision to prevent such impasses-which extend beyond lockdown situations to general conditional housing and support.

Review: Can digital mental health interventions bridge the 'digital divide' for socioeconomically and digitally marginalised youth? A systematic review

BACKGROUND

Digital mental health interventions (DMHIs) have the potential to improve the efficiency, accessibility and effectiveness of mental health services for young people, with the potential to reach socioeconomically and digitally marginalised young people with mental health needs who would otherwise not seek help in person. This review aims to investigate the characteristics, acceptability and efficacy of DMHIs specifically developed for socioeconomically and digitally marginalised youth.

METHOD

Key databases were searched widely and systematically (EMBASE, MEDLINE, PsycINFO, OpenGrey). Final inclusion in this review required studies to evaluate DMHIs specifically targeting socioeconomically and digitally marginalised children and young people through a broad range of research designs.

RESULTS

Ten studies, describing seven DHMIs, were included in this review. Studies varied in terms of methodology, population, intervention, outcome measures, technologies used and methodological quality. Qualitative and quantitative results are synthesised across three key phenomena of interest: effectiveness, acceptability and feasibility. Findings suggest that there is moderate but limited evidence supporting DMHIs for improving mental health outcomes among these populations.

CONCLUSIONS

While there is moderate evidence suggesting that digitally delivered interventions can be effective in improving mental health outcomes among socioeconomically and digitally marginalised youth, more high-quality research is needed in order to determine whether DMHIs can fully bridge the so-called 'digital divide'.

The Use of Technology to Provide Mental Health Services to Youth Experiencing Homelessness: Scoping Review

BACKGROUND

There is growing interest in using information and communication technologies (ICTs) to improve access to mental health services for youth experiencing homelessness (YEH); however, limited efforts have been made to synthesize this literature.

OBJECTIVE

This study aimed to review the research on the use of ICTs to provide mental health services and interventions for YEH.

METHODS

We used a scoping review methodology following the Arksey and O'Malley framework and guidelines from the Joanna Briggs Institute Manual for Evidence Synthesis. The results are reported according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement and the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews). A systematic search was conducted from 2005 to 2021 in MEDLINE, Embase, CINAHL, PsycInfo, Cochrane, Web of Science, and Maestro and in ProQuest Thesis and Dissertations, Papyrus, Homeless Hub, and Google Scholar for gray literature. Studies were included if participants' mean age was between 13 and 29 years, youth with mental health issues were experiencing homelessness or living in a shelter, ICTs were used as a means of intervention, and the study provided a description of the technology. The exclusion criteria were technology that did not allow for interaction (eg, television) and languages other than French or English. The data were analyzed using descriptive statistics and qualitative approaches. Two reviewers were involved in the screening and data extraction process in consultation with a third reviewer. The data were summarized in tables and by narrative synthesis.

RESULTS

From the 2153 abstracts and titles screened, 12 were included in the analysis. The most common types of ICTs used were communication technologies (eg, phone, video, and SMS text messages) and mobile apps. The intervention goals varied widely across studies; the most common goal was reducing risky behaviors, followed by addressing cognitive functioning, providing emotional support, providing vital resources, and reducing anxiety. Most studies (9/11, 82%) focused on the feasibility of interventions. Almost all studies reported high levels of acceptability (8/9, 89%) and moderate to high frequency of use (5/6, 83%). The principal challenges were related to technical problems such as the need to replace phones, issues with data services, and phone charging.

CONCLUSIONS

Our results indicate the emerging role of ICTs in the delivery of mental health services to YEH and that there is a high level of acceptability based on early feasibility studies. However, our results should be interpreted cautiously, considering the limited number of studies included in the analysis and the elevated levels of dropout. There is a need to advance efficacy and effectiveness research in this area with larger and longer studies.

Telemental Health for the Homeless Population: Lessons Learned when Leveraging Care

PURPOSE OF REVIEW

The purpose of this paper is to review key lessons when using telehealth within the context of mental health and homelessness. We examine technological and bandwidth issues the homeless population might face when getting telehealth services, discuss clinical process adaption needed for working remotely, and highlight the lessons learned when leveraging mental health services to homeless patients across telehealth platforms.

RECENT FINDINGS

Homelessness is associated with chronic, mental health disparities and access to mental health services is often less accessible among communities with unstable housing. Telehealth provides "OnDemand" treatment options while removing specific barriers found with in-person health care such as transportation, overwhelmed mental health facilities, i.e., appointment availability, and office hour limitations while reducing costs for both providers and patients. We provide two case examples to demonstrate successful delivery of telemental health services to homeless patients and review lessons learned when leveraging care.

Mental Health Emergency Hotlines in the United States: A Scoping Review (2012-2021)

OBJECTIVE

Mental health emergency hotlines provide clinical supports and connection to services. This scoping review describes the current literature on hotlines in the United States, including which populations they do and do not reach, typical call volumes and engagement levels, barriers to and facilitators of implementation, and common call outcomes. The review also identifies gaps in the literature and presents recommendations.

METHODS

A systematic search of peer-reviewed articles on U.S.-based telephone, text, and chat hotlines published between January 2012 and December 2021 retrieved 1,049 articles. In total, 96 articles met criteria for full-text review, of which 53 met full inclusion criteria.

RESULTS

Approximately half of the included studies (N=25) focused on descriptive information of callers, most of whom were females, younger adults, and White; veteran hotlines typically reached older men. Common reasons for calling were suicidality, depression, and interpersonal problems. Of studies examining intervention effects (N=20), few assessed hotlines as interventions (N=6), and few evaluated caller behavioral outcomes (N=4), reporting reduced distress and suicidality among callers after hotline engagement. However, these studies also suggested areas for improvement, including reaching underrepresented high-risk populations. Six studies reported implementation needs, such as investments in data collection and evaluation, staff training, and sustainable funding.

CONCLUSIONS

Hotlines appear to be more effective at reaching some populations than others, indicating that more intensive outreach efforts may be necessary to engage underrepresented high-risk populations. The findings also indicated limited evidence on the relationship between use of hotlines-particularly local text and chat hotlines-and caller outcomes, highlighting an area for further investigation.

Rates and correlates of well-being among youth experiencing homelessness

Mental health concerns have been well studied among youth experiencing homelessness, yet few studies have explored factors that contribute to well-being in this population. The current cross-sectional study examined rates and correlates of well-being among youth experiencing homelessness. This is a descriptive, secondary analysis of the baseline data from a clinical intervention study. Ninety-nine youth (aged 16-25) who were experiencing homelessness were recruited in Chicago. Approximately 40% of the sample reported average or above average well-being relative to existing benchmarks. Having medical insurance, a mobile phone, and a history of more severe childhood trauma were unique cross-sectional predictors of worse well-being (all ps < 0.034). A significant portion of our sample experienced well-being. Having access to certain resources may be counterintuitive indicators of poorer well-being among youth experiencing homelessness, perhaps because they are indicators of greater need or increased social comparison among these youth.

What twitter can tell us about user experiences of crisis text lines: A qualitative study

Mental health problems are the leading cause of disability worldwide. Despite the prevalence and cost of mental illness, there are insufficient health services to meet this demand. Crisis hotlines have a number of advantages for addressing mental health challenges and reducing barriers to support. Mental health crisis services have recently expanded beyond telephone hotlines to include other communication modalities such as chat and text messaging services, largely in response to the increased use of mobile phones and text messaging for social communication. Despite the high uptake of crisis text line services (CTLs) and rising mental health problems worldwide, CTLs remain understudied. The current study aimed to address an urgent need to evaluate user experiences with text-based crisis services. This study explored user experiences of CTLs by accessing users' publicly available Twitter posts that describe personal use and experience with CTLs. Data were qualitatively analyzed using thematic analysis. Six main themes were identified from 776 tweets: (1) approval of CTLs, (2) helpful counselling, (3) invalidating or unhelpful counselling, (4) problems with how the service is delivered, (5) features of the service that facilitate accessibility, and (6) indication that the service suits multiple needs. Overall, results provide evidence for the value of text-based crisis support, as many users reported positive experiences of effective counselling that provided helpful coping skills, de-escalation, and reduction of harm. Results also identified areas for improvement, particularly ensuring more timely service delivery and effective communication of empathy. Text-based services may require targeted training to apply methods that effectively convey empathy in this medium. Moving forward, CTL services will require systematic attention in the clinical research literature to ensure their continued success and popularity among users.

How Do People Who Are Homeless Find Out about Local Health and Social Care Services: A Mixed Method Study

BACKGROUND

There are significant numbers of people experiencing homelessness both in the UK and internationally. People who are homeless are much more likely to die prematurely and, therefore, need strong access to ongoing health and social care support if we hope to address the health disparity they face.

OBJECTIVES

The aim of the research was to explore how people who are homeless identify and locate appropriate health and social care services.

DESIGN

A mixed methods research study was applied on people who are currently homeless or had previously experienced homelessness.

SETTINGS

The research study was based in an urban area in the southwest of England. The area was chosen as it was identified to be in the top 24 local authorities for the number of homeless individuals.

PARTICIPANTS

A hundred individuals participated in the survey, of those 32% were living on the streets whilst 68% were living in temporary accommodation such as a charity home, shelter or a hotel paid for by the local authority. In addition, 16 participated in either a focus group or one-to-one interview Methods: The quantitative component consisted of a paper-based questionnaire whilst the qualitative aspect was focus groups/one-to-one interviews. The COREQ criteria were used in the report of the qualitative aspects of the study.

RESULTS

Quantitative data identified poor health in 90% of the sample. Access to both healthcare and wider wellbeing services (housing and food) was problematic and support for this was largely through third sector charity organisations. Qualitative data identified numerous systemic, individual and cultural obstacles, leaving difficulty for people in terms of knowing who to contact and how to access services, largely relying on word of mouth of other people who are homeless.

CONCLUSIONS

In order to address health inequities experienced by people who are homeless, there is a need to review how information regarding local health and wider wellbeing services is provided in local communities.

What Works Best to Engage Participants in Mobile App Interventions and e-Health: A Scoping Review

Background:

Despite the growing popularity of mobile app interventions, specific engagement components of mobile apps have not been well studied.

Methods:

The objectives of this scoping review are to determine which components of mobile health intervention apps encouraged or hindered engagement, and examine how studies measured engagement.

Results:

A PubMed search on March 5, 2020 yielded 239 articles that featured the terms engagement, mobile app/mobile health, and adult. After applying exclusion criteria, only 54 studies were included in the final analysis.

Discussion:

Common app components associated with increased engagement included: personalized content/feedback, data visualization, reminders/push notifications, educational information/material, logging/self-monitoring functions, and goal-setting features. On the other hand, social media integration, social forums, poor app navigation, and technical difficulties appeared to contribute to lower engagement rates or decreased usage. Notably, the review revealed a great variability in how engagement with mobile health apps is measured due to lack of established processes.

Conclusion:

There is a critical need for controlled studies to provide guidelines and standards to help facilitate engagement and its measurement in research and clinical trial work using mobile health intervention apps.

Smartphone Technology to Empower People Experiencing Homelessness: Secondary Analysis

BACKGROUND

In the United States, the number of people experiencing homelessness has continually increased over the last 3 years. Homelessness is associated with poor health, and people experiencing homelessness are often burdened with high rates of chronic and mental health conditions, functional limitations, and cognitive impairment. Despite the high burden of chronic illness and functional limitations, there is limited literature exploring self-management among homeless populations.

OBJECTIVE

This study aims to investigate how access to smartphone technology facilitates self-management, including the attainment of social needs within the context of homelessness.

METHODS

A secondary analysis of 33 exit interviews from 2 feasibility studies related to mobile health interventions among people experiencing homelessness was conducted. Iterative thematic analysis was used to identify themes representative of participants' experiences using smartphone technology.

RESULTS

Collectively, participants revealed not only how the context of homelessness constrained their ability to engage in activities necessary to self-manage health and meet social needs but also how consistent and predictable access to the tools available through a smartphone changed their behaviors and outlook. The global theme of empowered by technology was identified and defined as how having a smartphone with a plan for unlimited text, calling, data, and transportation allowed participants to navigate homelessness and facilitated self-management.

CONCLUSIONS

People experiencing homelessness used the tools on a smartphone to make decisions, take action, solve problems, and use the resources-skills necessary for fulfilling tasks required for effective self-management. Further, consistent access to smartphone technology and transportation empowered participants to meet the requirements for the attainment of social needs.

Evaluation of a Commercial Mobile Health App for Depression and Anxiety (AbleTo Digital+): Retrospective Cohort Study

BACKGROUND

Digital solutions, such as web-based and mobile interventions, have the potential to streamline pathways to mental health services and improve access to mental health care. Although a growing number of randomized trials have established the efficacy of digital interventions for common mental health problems, less is known about the real-world impact of these tools. AbleTo Digital+, a commercially available mental health app for depression and anxiety, offers a unique opportunity to understand the clinical impact of such tools delivered in a real-world context.

OBJECTIVE

The primary aim of this study is to examine the magnitude of change in depression and anxiety symptoms among individuals who used AbleTo Digital+ programs. The secondary aim is to evaluate Digital+ module completion, including the use of 1:1 coaching.

METHODS

In this retrospective cohort study, we analyzed previously collected and permanently deidentified data from a consecutive cohort of 1896 adults who initiated using one of the three Digital+ eight-module programs (depression, generalized anxiety, or social anxiety) between January 1 and June 30, 2020. Depression, generalized anxiety, and social anxiety symptoms were assessed within each program using the Patient Health Questionnaire-9, the Generalized Anxiety Disorder-7, and the Social Phobia Inventory, respectively. Linear mixed effects models were built to assess the association between module completion and symptom change among users who completed at least four modules and had at least mild baseline symptom elevations, controlling for age, gender, and baseline symptom severity. Digital+ use, including module completion, 1:1 coaching calls, and in-app coach messaging, was also evaluated.

RESULTS

Significant effects were observed among depression (Cohen d=1.5), generalized anxiety (Cohen d=1.2), and social anxiety (Cohen d=1.0) program participants who completed at least four modules and had mild baseline elevations (n=470). Associations between module completion and change in depression (β=-1.2; P<.001), generalized anxiety (β=-1.1; P<.001), and social anxiety (β=-2.4; P<.001) symptom scores retained significance with covariate adjustment. Participants completed an average of 2.6 (SD 2.7) modules. The average total length of app use was 52.2 (SD 83.5) days. Approximately two-thirds of the users engaged in at least 1 coaching call (66.82%, 1267/1896) or in-app text messaging (66.09%, 1253/1896). Participants who completed at least four modules participated in significantly more coaching calls per module (mean 1.1, SD 0.7) than users who completed fewer than four modules (mean 1.0, SD 1.2; t1407=-2.1; P=.03).

CONCLUSIONS

This study demonstrated that AbleTo Digital+ users experienced significant reductions in depression, generalized anxiety, and social anxiety symptoms throughout the program.

Use of Technology to Promote Health and Wellbeing of People Who Are Homeless: A Systematic Review

BACKGROUND

People who are homeless experience poorer health outcomes and challenges accessing healthcare contribute to the experienced health inequality. There has been an expansion in using technology to promote health and wellbeing and technology has the potential to enable people who are socially excluded, including those who are homeless, to be able to access health services. However, little research has been undertaken to explore how technology is used to promote health and wellbeing for those who are homeless. This review aims to address the questions: 'what mobile health (mHealth) related technology is used by homeless populations' and 'what is the health impact of mobile technology for homeless populations'?

METHODS

An integrative review methodology was employed. A systematic search of electronic databases was carried out between 4 January 2021 and 30 April 2021, searching for papers published between 2015 and 2021, which yielded 2113 hits, relevant papers were selected using specified inclusion and exclusion criteria reported using the Preferred Reporting Items for Systematic reviews and Meta-Analysis. The quality assessment of each paper included in the review was undertaken using the Mixed Methods Appraisal Tool.

RESULTS

Seventeen papers were selected for review and thematic analysis identified four themes: technology ownership, barriers to use, connectivity and health benefits.

CONCLUSION

It is evident that technology has the potential to support the health and wellbeing of individuals who are homeless; however, there are challenges regarding connectivity to the internet, as well as issues of trust in who has access to personal data and how they are used. Further research is needed to explore the use of health technology with people who are homeless to address these challenges.

Innovating Technology-Enhanced Interventions for Youth Suicide: Insights for Measuring Implementation Outcomes

Technology is one medium to increase youth engagement, especially among underserved and minority groups, in suicide preventive interventions. Technology can be used to supplement or adjunct an in-person intervention, guide an in-person intervention, or be the stand-alone (automated) component of the intervention. This range in technological use is now called the continuum of behavioral intervention technologies (BITs). Overall, suicide intervention researchers do not use this terminology to categorize how the role of technology differs across technology-enhanced youth interventions. There is growing recognition that technology-enhanced interventions will not create substantial public health impact without an understanding of the individual (youth, families, and providers), mezzo (clinics and health systems of care), and contextual factors (society, culture, community) that are associated with their implementation. Implementation science is the study of methods to promote uptake of evidence-based practices and policies into the broader health care system. In this review, we incorporate work from implementation science and BIT implementation to illustrate how the study of technology-enhanced interventions for youth suicide can be advanced by specifying the role of technology and measuring implementation outcomes.

Perceived Impacts, Acceptability, and Recommendations for Ecological Momentary Assessment Among Youth Experiencing Homelessness: Qualitative Study

BACKGROUND

The use of ecological momentary assessment (EMA) to study youth experiencing homelessness (YEH) behaviors is an emerging area of research. Despite high rates of participation and potential clinical utility, few studies have investigated the acceptability and recommendations for EMA from the YEH perspective.

OBJECTIVE

This study aimed to describe the perceived benefits, usability, acceptability, and barriers to the use of EMA from the homeless youth perspective.

METHODS

YEH were recruited from a larger EMA study. Semistructured exit interviews were performed using an interview guide that focused on the YEH experience with the EMA app, and included perceived barriers and recommendations for future studies. Data analyses used an inductive approach with thematic analysis to identify major themes and subthemes.

RESULTS

A total of 18 YEH aged 19-24 years participated in individual and group exit interviews. The EMA was highly acceptable to YEH and they found the app and EMA surveys easy to navigate. Perceived benefits included increased behavioral and emotional awareness with some YEH reporting a decrease in their high-risk behaviors as a result of participation. Another significant perceived benefit was the ability to use the phones for social support and make connections to family, friends, and potential employers. Barriers were primarily survey and technology related. Survey-related barriers included the redundancy of questions, the lack of customizable responses, and the timing of survey prompts. Technology-related barriers included the "freezing" of the app, battery charge, and connectivity issues. Recommendations for future studies included the need to provide real-time mental health support for symptomatic youth, to create individually customized questions, and to test the use of personalized motivational messages that respond to the EMA data in real time.

CONCLUSIONS

YEH are highly receptive to the use of EMA in studies. Further studies are warranted to understand the impact of EMA on YEH behaviors. Incorporating the YEH perspective into the design and implementation of EMA studies may help minimize barriers, increase acceptability, and improve participation rates in this hard-to-reach, disconnected population.

Addressing Intersecting Social and Mental Health Needs Among Transition-Age Homeless Youths: A Review of the Literature

Homelessness among youths is a poorly understood and complex social phenomenon. The authors examined the risk factors for homelessness among transition-age young adults, including the unique mental health concerns that often perpetuate the cycle of poverty and housing instability among these youths. The authors discuss the treatment gaps for mental health conditions in this population and identify potential solutions for reducing existing barriers to care. A literature review revealed that many studies report high rates of trauma and subsequent mental health problems among homeless youths. Intervention studies are challenging to conduct with this population and often have high attrition rates. Youths who are homeless desire mental health services and are especially enthusiastic about programs that address interpersonal difficulties and emotion regulation. Clinical data suggest that future interventions should address trauma more directly in this population. Technology-based interventions may help address the needs of homeless youths and may maximize their access to care. Because youths strongly prefer technology-based platforms, future research should integrate these platforms to better address the mental health needs identified as most salient by homeless youths. The authors discuss proposed policy changes at local, state, and federal levels to improve uptake of this proposed strategy.

[Homelessness and mental illnesses]

Wohnungslosigkeit ist Ausdruck ausgeprägter sozialer Exklusionsphänomene und trifft besonders häufig Menschen mit seelischen Erkrankungen. Hierbei gehen die Erkrankungen meist der Wohnungslosigkeit vorweg, wobei einige seelische Störungen erst infolge der Wohnungslosigkeit auftreten. International wurde eine Vielzahl therapeutischer Unterstützungsformen für wohnungslose Menschen mit seelischen Erkrankungen evaluiert mit vorwiegend aufsuchenden Behandlungsstrategien. Dies wird häufig kombiniert mit niedrigschwelliger Zurverfügungstellung von Wohnraum. Hierbei zeigen sich gute Effekte auf die Zeit des Verbleibs in Wohnungen und auf die Verbesserung psychiatrischer Symptome, allerdings keine ausreichenden Effekte auf Substanzgebrauchsstörungen. Möglichkeiten zukünftiger Projekte liegen am ehesten im Einbezug ehemals Betroffener und in der Verwendung digitaler Medien.
