Trends Influencing Future Delivery of Mental Health Services in Large Healthcare Systems

The delivery of mental health services, particularly psychotherapy and other psychosocial care, is being increasingly limited by financial constraints. We briefly review three trends that will play an increasingly important role in the delivery of mental health services in large organizations such as health maintenance organizations. These are (a) an increasing role for self-help and bibliotherapy interventions, both in traditional and electronic formats; (b) mental health services being offered in settings other than mental health specialty clinics; and (c) an increased emphasis on mechanisms for improving the quality and type of services offered, including quality improvement methods and pay-for-performance.     

Computerized Cognitive Behavior Therapy for Anxiety and Depression in Rural Areas: A Systematic Review

Background

People living in rural and remote communities have greater difficulty accessing mental health services and evidence-based therapies, such as cognitive behavior therapy (CBT), than their urban counterparts. Computerized CBT (CCBT) can be used to effectively treat depression and anxiety and may be particularly useful in rural settings where there are a lack of suitably trained practitioners.

Objective

To systematically review the global evidence regarding the clinical effectiveness and acceptability of CCBT interventions for anxiety and/or depression for people living in rural and remote locations.

Methods

We searched seven online databases: Medline, Embase Classic and Embase, PsycINFO, CINAHL, Web of Science, Scopus, and the Cochrane Library. We also hand searched reference lists, Internet search engines, and trial protocols. Two stages of selection were undertaken. In the first, the three authors screened citations. Studies were retained if they reported the efficacy, effectiveness or acceptability of CCBT for depression and/or anxiety disorders, were peer reviewed, and written in English. The qualitative data analysis software, NVivo 10, was then used to run automated text searches for the word “rural,” its synonyms, and stemmed words. All studies identified were read in full and were included in the study if they measured or meaningfully discussed the efficacy or acceptability of CCBT among rural participants.

Results

A total of 2594 studies were identified, of which 11 met the selection criteria and were included in the review. The studies that disaggregated efficacy data by location of participant reported that CCBT was equally effective for rural and urban participants. Rural location was found to both positively and negatively predict adherence across studies. CCBT may be more acceptable among rural than urban participants—studies to date showed that rural participants were less likely to want more face-to-face contact with a practitioner and found that computerized delivery addressed confidentiality concerns.

Conclusions

CCBT can be effective for addressing depression and anxiety and is acceptable among rural participants. Further work is required to confirm these results across a wider range of countries, and to determine the most feasible model of CCBT delivery, in partnership with people who live and work in rural and remote communities.     

Parental Facilitation of Adolescent Mental Health Service Utilization: A Conceptual and Empirical Review

Adolescent mental health service utilization has received increasing attention recently, with epidemiological studies revealing rates of service use that fall far below rates of psychopathology. Our primary aim in this article is to review and integrate current conceptions of the function that parents can serve in obtaining mental health services for adolescents. The review highlights the importance of developing a process-oriented model of service seeking. The initial parental help-seeking steps of gaining awareness of adolescents' distress and identifying specific emotional or behavioral problems receive particular attention. We stress that only by focusing on the role of parents and attending to specific developmental influences can the phenomenon of adolescent mental health service utilization be truly understood.     

Exercise Interventions for Mental Health: A Quantitative and Qualitative Review

Associations between exercise and mental well-being have been documented repeatedly over the last two decades. More recently, there has been application of exercise interventions to clinical populations diagnosed with depression, anxiety, and eating disorders with evidence of substantial benefit. Nonetheless, attention to the efficacy of exercise interventions in clinical settings has been notably absent in the psychosocial treatment literature, as have been calls for the integration of these methods within the clinical practice of psychologists. In this article, we provide a quantitative and qualitative review of these efficacy studies in clinical samples and discuss the potential mechanism of action of exercise interventions, with attention to both biological and psychosocial processes. The meta-analysis of 11 treatment outcome studies of individuals with depression yielded a very large combined effect size for the advantage of exercise over control conditions: g  = 1.39 (95% CI: .89–1.88), corresponding to a d  = 1.42 (95% CI: .92–1.93). Based on these findings, we encourage clinicians to consider the role of adjunctive exercise interventions in their clinical practice and we discuss issues concerning this integration.     

Web-Based Intervention Programs for Depression: A Scoping Review and Evaluation

Background

Although depression is known to affect millions of people worldwide, individuals seeking aid from qualified health care professionals are faced with a number of barriers to treatment including a lack of treatment resources, limited number of qualified service providers, stigma associated with diagnosis and treatment, prolonged wait times, cost, and barriers to accessibility such as transportation and clinic locations. The delivery of depression interventions through the Internet may provide a practical solution to addressing some of these barriers.

Objective

The purpose of this scoping review was to answer the following questions: (1) What Web-delivered programs are currently available that offer an interactive treatment component for depression?, (2) What are the contents, accessibility, and usability of each identified program?, and (3) What tools, supports, and research evidence are available for each identified program?

Methods

Using the popular search engines Google, Yahoo, and Bing (Canadian platforms), two reviewers independently searched for interactive Web-based interventions targeting the treatment of depression. The Beacon website, an information portal for online health applications, was also consulted. For each identified program, accessibility, usability, tools, support, and research evidence were evaluated and programs were categorized as evidence-based versus non-evidence-based if they had been the subject of at least one randomized controlled trial. Programs were scored using a 28-point rating system, and evidence- versus non-evidence-based programs were compared and contrasted. Although this review included all programs meeting exclusion and inclusion criteria found using the described search method, only English language Web-delivered depression programs were awarded an evaluation score.

Results

The review identified 32 programs meeting inclusion criteria. There was a great deal of variability among the programs captured in this evaluation. Many of the programs were developed for general adolescent or adult audiences, with few (n=2) focusing on special populations (eg, military personnel, older adults). Cognitive behavioral therapy was the most common therapeutic approach used in the programs described. Program interactive components included mood assessments and supplementary homework sheets such as activity planning and goal setting. Only 12 of the programs had published evidence in support of their efficacy and treatment of depressive symptoms.

Conclusions

There are a number of interactive depression interventions available through the Internet. Recommendations for future programs, or the adaptation of existing programs include offering a greater selection of alternative languages, removing registration restrictions, free trial periods for programs requiring user fees, and amending programs to meet the needs of special populations (eg, those with cognitive and/or visual impairments). Furthermore, discussion of specific and relevant topics to the target audience while also enhancing overall user control would contribute to a more accessible intervention tool.

Community attitudes to the appropriation of mobile phones for monitoring and managing depression, anxiety, and stress

Background

The benefits of self-monitoring on symptom severity, coping, and quality of life have been amply demonstrated. However, paper and pencil self-monitoring can be cumbersome and subject to biases associated with retrospective recall, while computer-based monitoring can be inconvenient in that it relies on users being at their computer at scheduled monitoring times. As a result, nonadherence in self-monitoring is common. Mobile phones offer an alternative. Their take-up has reached saturation point in most developed countries and is increasing in developing countries; they are carried on the person, they are usually turned on, and functionality is continually improving. Currently, however, public conceptions of mobile phones focus on their use as tools for communication and social identity. Community attitudes toward using mobile phones for mental health monitoring and self-management are not known.

Objective

The objective was to explore community attitudes toward the appropriation of mobile phones for mental health monitoring and management.

Methods

We held community consultations in Australia consisting of an online survey (n = 525), focus group discussions (n = 47), and interviews (n = 20).

Results

Respondents used their mobile phones daily and predominantly for communication purposes. Of those who completed the online survey, the majority (399/525 or 76%) reported that they would be interested in using their mobile phone for mental health monitoring and self-management if the service were free. Of the 455 participants who owned a mobile phone or PDA, there were no significant differences between those who expressed interest in the use of mobile phones for this purpose and those who did not by gender (χ2₁, = 0.98, P = .32, phi = .05), age group (χ2₄, = 1.95, P = .75, phi = .06), employment status (χ2₂, = 2.74, P = .25, phi = .08) or marital status (χ2₄, = 4.62, P = .33, phi = .10). However, the presence of current symptoms of depression, anxiety, or stress affected interest in such a program in that those with symptoms were more interested (χ² ₁, = 16.67, P < .001, phi = .19). Reasons given for interest in using a mobile phone program were that it would be convenient, counteract isolation, and help identify triggers to mood states. Reasons given for lack of interest included not liking to use a mobile phone or technology, concerns that it would be too intrusive or that privacy would be lacking, and not seeing the need. Design features considered to be key by participants were enhanced privacy and security functions including user name and password, ease of use, the provision of reminders, and the availability of clear feedback.

Conclusions

Community attitudes toward the appropriation of mobile phones for the monitoring and self-management of depression, anxiety, and stress appear to be positive as long as privacy and security provisions are assured, the program is intuitive and easy to use, and the feedback is clear.     

School‐Based Mental Health and Behavioral Programs for Low‐Income,Urban Youth: A Systematic and Meta‐Analytic Review

[Clin Psychol Sci Prac 18: 372–390, 2011] A systematic and meta‐analytic review was conducted of the effectiveness of school‐based mental health and behavioral programs for low‐income, urban youth. Applying criteria from an earlier systematic review ( Rones & Hoagwood, 2000 ) of such programs for all populations indicated substantially fewer effective programs for low‐income, urban youth. The meta‐analysis similarly failed to indicate effects of the typical program on primary outcomes. Effectiveness was evident, however, for programs that targeted internalizing problems or had a broader socio‐emotional focus and those delivered to all youth (i.e., universal). In contrast, negative effects were apparent for programs that targeted externalizing problems and were delivered selectively to youth with existing problems. Distinctive characteristics of low‐income, urban schools and nonschool environments are emphasized as potential explanations for the findings.     

Adherence in Internet Interventions for Anxiety and Depression: Systematic Review

Background

Open access websites which deliver cognitive and behavioral interventions for anxiety and depression are characterised by poor adherence. We need to understand more about adherence in order to maximize the impact of Internet-based interventions on the disease burden associated with common mental disorders.

Objective

The aims of this paper are to review briefly the adherence literature with respect to Internet interventions and to investigate the rates of dropout and compliance in randomized controlled trials of anxiety and depression Web studies.

Methods

A systematic review of randomized controlled trials using Internet interventions for anxiety and depression was conducted, and data was collected on dropout and adherence, predictors of adherence, and reasons for dropout.

Results

Relative to reported rates of dropout from open access sites, the present study found that the rates of attrition in randomized controlled trials were lower, ranging from approximately 1 - 50%. Predictors of adherence included disease severity, treatment length, and chronicity. Very few studies formally examined reasons for dropout, and most studies failed to use appropriate statistical techniques to analyze missing data.

Conclusions

Dropout rates from randomized controlled trials of Web interventions are low relative to dropout from open access websites. The development of theoretical models of adherence is as important in the area of Internet intervention research as it is in the behavioral health literature. Disease-based factors in anxiety and depression need further investigation.     

Computer-Delivered and Web-Based Interventions to Improve Depression,Anxiety, and Psychological Well-Being of University Students: A Systematic Review and Meta-Analysis

Background

Depression and anxiety are common mental health difficulties experienced by university students and can impair academic and social functioning. Students are limited in seeking help from professionals. As university students are highly connected to digital technologies, Web-based and computer-delivered interventions could be used to improve students’ mental health. The effectiveness of these intervention types requires investigation to identify whether these are viable prevention strategies for university students.

Objective

The intent of the study was to systematically review and analyze trials of Web-based and computer-delivered interventions to improve depression, anxiety, psychological distress, and stress in university students.

Methods

Several databases were searched using keywords relating to higher education students, mental health, and eHealth interventions. The eligibility criteria for studies included in the review were: (1) the study aimed to improve symptoms relating to depression, anxiety, psychological distress, and stress, (2) the study involved computer-delivered or Web-based interventions accessed via computer, laptop, or tablet, (3) the study was a randomized controlled trial, and (4) the study was trialed on higher education students. Trials were reviewed and outcome data analyzed through random effects meta-analyses for each outcome and each type of trial arm comparison. Cochrane Collaboration risk of bias tool was used to assess study quality.

Results

A total of 17 trials were identified, in which seven were the same three interventions on separate samples; 14 reported sufficient information for meta-analysis. The majority (n=13) were website-delivered and nine interventions were based on cognitive behavioral therapy (CBT). A total of 1795 participants were randomized and 1480 analyzed. Risk of bias was considered moderate, as many publications did not sufficiently report their methods and seven explicitly conducted completers’ analyses. In comparison to the inactive control, sensitivity meta-analyses supported intervention in improving anxiety (pooled standardized mean difference [SMD] −0.56; 95% CI −0.77 to −0.35, P<.001), depression (pooled SMD −0.43; 95% CI −0.63 to −0.22, P<.001), and stress (pooled SMD −0.73; 95% CI −1.27 to −0.19, P=.008). In comparison to active controls, sensitivity analyses did not support either condition for anxiety (pooled SMD −0.18; 95% CI −0.98 to 0.62, P=.66) or depression (pooled SMD −0.28; 95% CI −0.75 to −0.20, P=.25). In contrast to a comparison intervention, neither condition was supported in sensitivity analyses for anxiety (pooled SMD −0.10; 95% CI −0.39 to 0.18, P=.48) or depression (pooled SMD −0.33; 95% CI −0.43 to 1.09, P=.40).

Conclusions

The findings suggest Web-based and computer-delivered interventions can be effective in improving students’ depression, anxiety, and stress outcomes when compared to inactive controls, but some caution is needed when compared to other trial arms and methodological issues were noticeable. Interventions need to be trialed on more heterogeneous student samples and would benefit from user evaluation. Future trials should address methodological considerations to improve reporting of trial quality and address post-intervention skewed data.

Community‐Based Mental Health and Behavioral Programs for Low‐Income Urban Youth: A Meta‐Analytic Review

A meta‐analytic review of 33 studies and 41 independent samples was conducted of the effectiveness of community‐based mental health and behavioral programs for low‐income urban youth. Findings indicated positive effects, with an overall mean effect of 0.25 at post‐test. While this is comparable to previous meta‐analytic intervention research with more diverse samples, it stands in contrast to findings of the school‐based review (0.08 at post‐test) focused on this population. The current review found type of intervention to significantly moderate effects, with effects highest for programs that were environmentally based. In fact, effect sizes for programs that did not target the environment were not significant. Findings are discussed with an emphasis on environmental influences, including the differing contexts affecting school‐ versus community‐based interventions conducted with low‐income, urban youth.     

Mobile Apps for Bipolar Disorder: A Systematic Review of Features and Content Quality

Background

With continued increases in smartphone ownership, researchers and clinicians are investigating the use of this technology to enhance the management of chronic illnesses such as bipolar disorder (BD). Smartphones can be used to deliver interventions and psychoeducation, supplement treatment, and enhance therapeutic reach in BD, as apps are cost-effective, accessible, anonymous, and convenient. While the evidence-based development of BD apps is in its infancy, there has been an explosion of publicly available apps. However, the opportunity for mHealth to assist in the self-management of BD is only feasible if apps are of appropriate quality.

Objective

Our aim was to identify the types of apps currently available for BD in the Google Play and iOS stores and to assess their features and the quality of their content.

Methods

A systematic review framework was applied to the search, screening, and assessment of apps. We searched the Australian Google Play and iOS stores for English-language apps developed for people with BD. The comprehensiveness and quality of information was assessed against core psychoeducation principles and current BD treatment guidelines. Management tools were evaluated with reference to the best-practice resources for the specific area. General app features, and privacy and security were also assessed.

Results

Of the 571 apps identified, 82 were included in the review. Of these, 32 apps provided information and the remaining 50 were management tools including screening and assessment (n=10), symptom monitoring (n=35), community support (n=4), and treatment (n=1). Not even a quarter of apps (18/82, 22%) addressed privacy and security by providing a privacy policy. Overall, apps providing information covered a third (4/11, 36%) of the core psychoeducation principles and even fewer (2/13, 15%) best-practice guidelines. Only a third (10/32, 31%) cited their information source. Neither comprehensiveness of psychoeducation information (r=-.11, P=.80) nor adherence to best-practice guidelines (r=-.02, P=.96) were significantly correlated with average user ratings. Symptom monitoring apps generally failed to monitor critical information such as medication (20/35, 57%) and sleep (18/35, 51%), and the majority of self-assessment apps did not use validated screening measures (6/10, 60%).

Conclusions

In general, the content of currently available apps for BD is not in line with practice guidelines or established self-management principles. Apps also fail to provide important information to help users assess their quality, with most lacking source citation and a privacy policy. Therefore, both consumers and clinicians should exercise caution with app selection. While mHealth offers great opportunities for the development of quality evidence-based mobile interventions, new frameworks for mobile mental health research are needed to ensure the timely availability of evidence-based apps to the public.     

Effectiveness of Web-Delivered Acceptance and Commitment Therapy in Relation to Mental Health and Well-Being: A Systematic Review and Meta-Analysis

BackgroundThe need for effective interventions to improve mental health and emotional well-being at a population level are gaining prominence both in the United Kingdom and globally. Advances in technology and widespread adoption of Internet capable devices have facilitated rapid development of Web-delivered psychological therapies. Interventions designed to manage a range of affective disorders by applying diverse therapeutic approaches are widely available.ObjectiveThe main aim of this review was to evaluate the evidence base of acceptance and commitment therapy (ACT) in a Web-based delivery format.MethodA systematic review of the literature and meta-analysis was conducted. Two electronic databases were searched for Web-delivered interventions utilizing ACT for the management of affective disorders or well-being. Only Randomized Controlled Trials (RCTs) were included.ResultsThe search strategy identified 59 articles. Of these, 10 articles met the inclusion criteria specified. The range of conditions and outcome measures that were identified limited the ability to draw firm conclusions about the efficacy of Web-delivered ACT-based intervention for anxiety or well-being.ConclusionsACT in a Web-based delivery format was found to be effective in the management of depression. Rates of adherence to study protocols and completion were high overall suggesting that this therapeutic approach is highly acceptable for patients and the general public.     

A Reason for Optimism in Rural Mental Health Care: Emerging Solutions and Models of Service Delivery

This invited commentary responds to Jameson and Blank's literature review (2007) and utilizes different source materials, such as personal communications among clinicians and policymakers, Internet-based information, and direct professional experience. An update is provided regarding new graduate programs training clinicians for rural service. In addition, perceived barriers to treatment are challenged, because they are drawn from research results that could be interpreted in different ways, given the cultural heritage of southern and central Appalachian people. Lastly, the efforts of the Veterans Affairs Health Care System to reach rural citizens for mental health treatment are summarized. Some of these federal processes could be replicated at the state level, if sociopolitical and economic factors were more directly addressed. The commentary concludes, from the perspective of a professional providing clinical services in a rural setting, that a more optimistic outlook on the state of rural mental health care may be warranted.     

Mental health and discrimination among migrants from Africa: An Italian cross-sectional study

This study aimed to assess depression, anxiety, posttraumatic stress disorder (PTSD) and discrimination in African migrants and investigate determinants. A cross-sectional study was conducted in Italy (July 2019–February 2020). Inclusion criteria: being a citizen of an African country or having parents who are citizens of an African country. Questionnaires included tests for depression, anxiety, PTSD, discrimination. Multivariable regressions were performed. Participants were 293. The prevalence of depression, anxiety, and PTSD was: 12.1%, 12.1%, and 24.4%. Only 7.2% declared not to be discriminated. Among significantly associated factors, waiting for/being in possession of temporary permits and discrimination were associated with all mental outcomes. Being (or having parents from) Sub-Saharan Africa increased the likelihood of discrimination. A relevant prevalence of mental illnesses was reported. Particularly, Sub-Saharan Africans potentially offer a unique point of view. Migrants' mental health should be a priority for national and international programs of health monitoring.     

Preconception Care Education for Women With Diabetes: A Systematic Review of Conventional and Digital Health Interventions

BackgroundWorldwide, 199.5 million women have diabetes mellitus (DM). Preconception care (PCC) education starting from adolescence has been recommended as an effective strategy for safeguarding maternal and child health. However, traditional preconception care advice provided by health care professionals (HCPs) within clinic settings is hindered by inadequate resources, suboptimal coverage, and busy clinics. Electronic health (eHealth), which is instrumental in solving problems around scarce health resources, could be of value in overcoming these limitations and be used to improve preconception care and pregnancy outcomes for women with DM.ObjectiveThe objectives were to: (1) identify, summarize, and critically appraise the current methods of providing PCC education; (2) examine the relationship between PCC educational interventions (including use of technology as an intervention medium) on patient and behavioral outcomes; and (3) highlight limitations of current interventions and make recommendations for development of eHealth in this field.MethodsElectronic databases were searched using predefined search terms for PCC education in women with type 1 or 2 DM for quantitative studies from 2003 until June 2016. Of the 1969 titles identified, 20 full papers were retrieved and 12 papers were included in this review.ResultsThe reviewed studies consistently reported that women receiving educational interventions via health care professionals and eHealth had significantly improved levels of glycosylated hemoglobin (P<.001) with fewer preterm deliveries (P=.02) and adverse fetal outcomes (P=.03). Significant improvements in knowledge (P<.001) and attitudes toward seeking PCC (P=.003) were reported along with reduced barriers (P<.001).ConclusionsPCC has a positive effect on pregnancy outcomes for women with DM. However, uptake of PCC is low and the use of eHealth applications for PCC of women with DM is still in its infancy. Initial results are promising; however, future research incorporating mobile phones and apps is needed. Clearly, there is much to be done if the full potential of eHealth PCC to improve obstetric outcomes for women with DM is to be realized.     

Young Men, Mental Health, and Technology: Implications for Service Design and Delivery in the Digital Age

Background

Young men are particularly vulnerable to suicide, drug, and alcohol problems and yet fail to seek appropriate help. An alternative or adjunct to face-to-face services has emerged with widespread uptake of the Internet and related communication technologies, yet very little evidence exists that examines the capacity of the Internet to engage young men and promote help seeking.

Objective

To explore young people’s attitudes and behaviors in relation to mental health and technology use. The aim was to identify key gender differences to inform the development of online mental health interventions for young men.

Methods

A cross-sectional online survey of 1038 young people (aged 16 to 24 years) was used.

Results

Young men are more likely than young women to play computer games, access online video/music content, and visit online forums. More than half of young men and women reported that they sought help for a problem online, and the majority were satisfied with the help they received. Significant gender differences were identified in relation to how young people would respond to a friend in need, with young men being less likely than young women to confront the issue directly.

Conclusions

Online interventions for young men need to be action-oriented, informed by young men’s views and everyday technology practices, and leverage the important role that peers play in the help-seeking process.     

Understanding the Usage of Content in a Mental Health Intervention for Depression: An Analysis of Log Data

Background

Web-based interventions for the early treatment of depressive symptoms can be considered effective in reducing mental complaints. However, there is a limited understanding of which elements in an intervention contribute to effectiveness. For efficiency and effectiveness of interventions, insight is needed into the use of content and persuasive features.

Objective

The aims of this study were (1) to illustrate how log data can be used to understand the uptake of the content of a Web-based intervention that is based on the acceptance and commitment therapy (ACT) and (2) to discover how log data can be of value for improving the incorporation of content in Web-based interventions.

Methods

Data from 206 participants (out of the 239) who started the first nine lessons of the Web-based intervention, Living to the Full, were used for a secondary analysis of a subset of the log data of the parent study about adherence to the intervention. The log files used in this study were per lesson: login, start mindfulness, download mindfulness, view success story, view feedback message, start multimedia, turn on text-message coach, turn off text-message coach, and view text message. Differences in usage between lessons were explored with repeated measures ANOVAs (analysis of variance). Differences between groups were explored with one-way ANOVAs. To explore the possible predictive value of the login per lesson quartiles on the outcome measures, four linear regressions were used with login quartiles as predictor and with the outcome measures (Center for Epidemiologic Studies—Depression [CES-D] and the Hospital Anxiety and Depression Scale—Anxiety [HADS-A] on post-intervention and follow-up) as dependent variables.

Results

A significant decrease in logins and in the use of content and persuasive features over time was observed. The usage of features varied significantly during the treatment process. The usage of persuasive features increased during the third part of the ACT (commitment to value-based living), which might indicate that at that stage motivational support was relevant. Higher logins over time (9 weeks) corresponded with a higher usage of features (in most cases significant); when predicting depressive symptoms at post-intervention, the linear regression yielded a significant model with login quartile as a significant predictor (explained variance is 2.7%).

Conclusions

A better integration of content and persuasive features in the design of the intervention and a better intra-usability of features within the system are needed to identify which combination of features works best for whom. Pattern recognition can be used to tailor the intervention based on usage patterns from the earlier lessons and to support the uptake of content essential for therapy. An adaptable interface for a modular composition of therapy features supposes a dynamic approach for Web-based treatment; not a predefined path for all, but a flexible way to go through all features that have to be used.
