Background Despite growing interest in mobile mental health and utilization of smartphone technology to monitor psychiatric symptoms, there remains a lack of knowledge both regarding patient ownership of smartphones and their interest in using such to monitor their mental health. Objective To provide data on psychiatric outpatients’ prevalence of smartphone ownership and interest in using their smartphones to run applications to monitor their mental health. Methods We surveyed 320 psychiatric outpatients from four clinics around the United States in order to capture a geographically and socioeconomically diverse patient population. These comprised a state clinic in Massachusetts (n=108), a county clinic in California (n=56), a hybrid public and private clinic in Louisiana (n=50), and a private/university clinic in Wisconsin (n=106). Results Smartphone ownership and interest in utilizing such to monitor mental health varied by both clinic type and age with overall ownership of 62.5% (200/320), which is slightly higher than the average United States’ rate of ownership of 58% in January 2014. Overall patient interest in utilizing smartphones to monitor symptoms was 70.6% (226/320). Conclusions These results suggest that psychiatric outpatients are interested in using their smartphones to monitor their mental health and own the smartphones capable of running mental healthcare related mobile applications.

Abstract Telepsychiatry (TP; video; synchronous) is effective, well received and a standard way to practice. Best practices in TP education, but not its desired outcomes, have been published. This paper proposes competencies for trainees and clinicians, with TP situated within the broader landscape of e-mental health (e-MH) care. TP competencies are organized using the US Accreditation Council of Graduate Medical Education framework, with input from the CanMEDS framework. Teaching and assessment methods are aligned with target competencies, learning contexts, and evaluation options. Case examples help to apply concepts to clinical and institutional contexts. Competencies can be identified, measured and evaluated. Novice or advanced beginner, competent/proficient, and expert levels were outlined. Andragogical (i.e. pedagogical) methods are used in clinical care, seminar, and other educational contexts. Cross-sectional and longitudinal evaluation using quantitative and qualitative measures promotes skills development via iterative feedback from patients, trainees, and faculty staff. TP and e-MH care significantly overlap, such that institutional leaders may use a common approach for change management and an e-platform to prioritize resources. TP training and assessment methods need to be implemented and evaluated. Institutional approaches to patient care, education, faculty development, and funding also need to be studied.

Mobile Tele-Mental Health: Increasing Applications and a Move to Hybrid Models of Care

Steven Chan; John Torous; Ladson Hinton; Peter Yellowlees

Mobile telemental health is defined as the use of mobile phones and other wireless devices as applied to psychiatric and mental health practice. Applications of such include treatment monitoring and adherence, health promotion, ecological momentary assessment, and decision support systems. Advantages of mobile telemental health are underscored by its interactivity, just-in-time interventions, and low resource requirements and portability. Challenges in realizing this potential of mobile telemental health include the low penetration rates of health applications on mobile devices in part due to health literacy, the delay in current published research in evaluating newer technologies, and outdated research methodologies. Despite such challenges, one immediate opportunity for mobile telemental health is utilizing mobile devices as videoconferencing mediums for psychotherapy and psychosocial interventions enhanced by novel sensor based monitoring and behavior-prediction algorithms. This paper provides an overview of mobile telemental health and its current trends, as well as future opportunities as applied to patient care in both academic research and commercial ventures.

Towards a Framework for Evaluating Mobile Mental Health Apps

Steven Chan; John Torous; Ladson Hinton; Peter Yellowlees

INTRODUCTION Mobile phones are ubiquitous in society and owned by a majority of psychiatric patients, including those with severe mental illness. Their versatility as a platform can extend mental health services in the areas of communication, self-monitoring, self-management, diagnosis, and treatment. However, the efficacy and reliability of publicly available applications (apps) have yet to be demonstrated. Numerous articles have noted the need for rigorous evaluation of the efficacy and clinical utility of smartphone apps, which are largely unregulated. Professional clinical organizations do not provide guidelines for evaluating mobile apps. MATERIALS AND METHODS Guidelines and frameworks are needed to evaluate medical apps. Numerous frameworks and evaluation criteria exist from the engineering and informatics literature, as well as interdisciplinary organizations in similar fields such as telemedicine and healthcare informatics. RESULTS We propose criteria for both patients and providers to use in assessing not just smartphone apps, but also wearable devices and smartwatch apps for mental health. Apps can be evaluated by their usefulness, usability, and integration and infrastructure. Apps can be categorized by their usability in one or more stages of a mental health providers workflow. CONCLUSIONS Ultimately, leadership is needed to develop a framework for describing apps, and guidelines are needed for both patients and mental health providers.

Background There are over 165,000 mHealth apps currently available to patients, but few have undergone an external quality review. Furthermore, no standardized review method exists, and little has been done to examine the consistency of the evaluation systems themselves. Objective We sought to determine which measures for evaluating the quality of mHealth apps have the greatest interrater reliability. Methods We identified 22 measures for evaluating the quality of apps from the literature. A panel of 6 reviewers reviewed the top 10 depression apps and 10 smoking cessation apps from the Apple iTunes App Store on these measures. Krippendorff’s alpha was calculated for each of the measures and reported by app category and in aggregate. Results The measure for interactiveness and feedback was found to have the greatest overall interrater reliability (alpha=.69). Presence of password protection (alpha=.65), whether the app was uploaded by a health care agency (alpha=.63), the number of consumer ratings (alpha=.59), and several other measures had moderate interrater reliability (alphas>.5). There was the least agreement over whether apps had errors or performance issues (alpha=.15), stated advertising policies (alpha=.16), and were easy to use (alpha=.18). There were substantial differences in the interrater reliabilities of a number of measures when they were applied to depression versus smoking apps. Conclusions We found wide variation in the interrater reliability of measures used to evaluate apps, and some measures are more robust across categories of apps than others. The measures with the highest degree of interrater reliability tended to be those that involved the least rater discretion. Clinical quality measures such as effectiveness, ease of use, and performance had relatively poor interrater reliability. Subsequent research is needed to determine consistent means for evaluating the performance of apps. Patients and clinicians should consider conducting their own assessments of apps, in conjunction with evaluating information from reviews.

Telepsychiatry: Effective, Evidence-Based, and at a Tipping Point in Health Care Delivery?

Donald M. Hilty; Peter Yellowlees; Michelle B. Parrish; Steven Chan

Patient-centered health care questions how to deliver quality, affordable, and timely care in a variety of settings. Telemedicine empowers patients, increases administrative efficiency, and ensures expertise gets to the place it is most needed--the patient. Telepsychiatry or telemental health is effective, well accepted, and comparable to in-person care. E-models of care offer variety, flexibility, and positive outcomes in most settings, and clinicians are increasingly interested in using technology for care, so much so that telepsychiatry is now being widely introduced around the world.

Human Papillomavirus and Blastocyst Apoptosis

Joan H. Calinisan; Steven Chan; Alan King; Philip J. Chan

AbstractPurpose: The effect of human papillomavirus (HPV) DNA from the E6-E7 region on the integrity of DNA in blastocyst stage embryonic cells was studied. The study design paralleled the event whereby HPV DNA from the infecting virus would target host cell DNA. The objectives were (a) to determine if the DNA of blastocysts were disrupted by the presence of HPV DNA and (b) to determine if the intensity of DNA damage was associated with the type of HPV. Methods: This study involved superovulating female mice, mating, collecting one-cell embryos, and culturing to the expanded blastocyst stage. The blastocysts were infected with PCR-synthesized DNA fragments from either HPV type 16, 18, 31, or 33. The blastocyst DNA were analyzed by comet assay after 24 h of incubation. The fluorescent images were digitized and the pixel intensity of each blastocyst was measured. Results: Only the DNA of HPV type 16 was associated with significant DNA fragmentation in comparison with the other HPV types. There was no relationship between HPV DNA fragment size and the intensity of DNA fragmentation. Conclusions: The data suggested that one mode of action of HPV type 16 was to initiate apoptosis of embryonic cells through DNA fragmentation. The effect of HPV 16 occurred rapidly within 24 h. The intensity of DNA damage was not linked to the specific type of HPV. However, the results do not rule out the other HPV types affecting embryos under conditions different from this study.

Certification of Mobile Apps for Health Care

Steven Chan; Satish Misra

In Reply We share Dr Constantino’s interest in determining if there are differences in the etiology of ASD between males and females. We did not compare the heritability of ASD between males and females in the study for 2 reasons. First, even a large population-based study such as ours has limited power to detect statistically significant sex differences in heritability. Second, we addressed the question of sex effects in our recurrence risk analysis. We did not observe important or statistically significant differences in recurrence risk in siblings and cousins for the different sibling and cousin sex combinations. The relative risk for males or females was not dependent on the sex of the proband. Furthermore, an epidemiological study from Denmark also did not find support for sex-related differences in recurrence risk.1 We look forward to seeing this topic addressed further in future populationbased studies. Several factors may affect concordance rates. Some earlier twin studies used interviews, rating scales, or both to score different autistic traits and applied preselected cutoffs to define autism.2,3 The pairwise concordance using such an approach may differ from pairwise concordance based on clinical diagnosis as reflected in our study. The source population, methods of ascertainment, handling of time trends, and participation rates may also affect observed concordance rates. The models we fitted are complex and, like any statistical model, do come with some underlying assumptions. Furthermore, the models can only give crude estimates of the sources and nature of the disease, and therefore we were cautious not to overinterpret our estimates or speculate what the exact sources underlying our estimates might be. Yet one of the potential important results of an analysis such as ours is to facilitate and stimulate a discussion about the specific causes of the disorder. One way to address current concerns about behavioral genetic models of heritability is to complement them with modeling methods using molecular data to estimate heritable and nonheritable factors. We agree with Constantino that de novo mutations would inflate the nonshared environment component term and this may be important.

New Frontiers in Healthcare and Technology: Internet-and Web-Based Mental Options Emerge to Complement In-Person and Telepsychiatric Care Options

Donald M. Hilty; Steven Chan; John Torous; Jesse Matmahur; Davor Mucic

Background: Web and Internet-based resources are remarkably popular with the public, patients and others as a way to access mental health information, tools for self-care, advice/consultation from a professional, and providerdirected treatments. Objective: This paper provides a framework of a spectrum that includes person-centered health education options (conceptual endpoint), patient and caregiver-centered mental health care interventions (evidence-based literature review), and more formal provider-directed treatments (conceptual endpoint). Methods: The evidence-based literature review was focused on treatment studies, using a minimum of three key words and the 1996-2015 period, resulting in 13,612 articles. This was reduced to 388 (title words used), to 125 (abstracts for methods, design, and outcomes) and 40 (evidence-based criteria of guidelines). Results: Technology is frequently used, is readily accessible and satisfies persons, patients, and caregivers. Its impact on openness to engage with others and begin self-care appears very positive; its ability to help people change behaviors and engage additional clinical services appears modest, though this is inadequately evaluated. Formal treatments over the Internet, asynchronous care models, or traditional video-based synchronous services are as good as or better than in-person services, though an incomplete range of services has been evaluated. Relatively few treatment studies assess outcomes, compare in-person and e-Mental Health care, and or compare technology-based care options to one another; hybrid models of care have emerged, but have rarely been studied. Conclusions: For persons or patients not in care, use of the internet for common, non-acute problems appears to work, though a one-time clinical evaluation may help them place options in context. Clinicians and patients should specifically plan how to use technology and exercise sound judgment, based on guidelines when available. More research is needed on the application of new technologies to clinical care, with randomized trials and health services studies for effectiveness suggested.

Blogging and Social Media for Mental Health Education and Advocacy: a Review for Psychiatrists

Holly S. Peek; Misty Richards; Owen S. Muir; Steven Chan; Michael Caton; Carlene MacMillan

We live in a digital age where information can be found instantaneously via the Internet. Studies have shown that consumers search for much of their medical information on the Internet, particularly utilizing blogs and social media platforms. As the mental health field is riddled with misinformation and stigma, this offers a unique opportunity for psychiatrists and mental health professionals to reach a broad audience for mental health education and advocacy. In this review, we discuss the various methods and techniques for blogging and social media. We then review the current recommendations for ethics and professionalism as well as make recommendations to strengthen our guidance in this new and evolving field.
