Engaging adolescents in a computer-based weight management program: avatars and virtual coaches could help.

OBJECTIVE: This research focuses on the potential ability of animated avatars (a digital representation of the user) and virtual agents (a digital representation of a coach, buddy, or teacher) to deliver computer-based interventions for adolescents' chronic weight management. An exploration of the acceptance and desire of teens to interact with avatars and virtual agents for self-management and behavioral modification was undertaken. MATERIALS AND METHODS: The utilized approach was inspired by community-based participatory research. Data was collected from 2 phases: Phase 1) focus groups with teens, provider interviews, parent interviews; and Phase 2) mid-range prototype assessment by teens and providers. RESULTS: Data from all stakeholder groups expressed great interest in avatars and virtual agents assisting self-management efforts. Adolescents felt the avatars and virtual agents could: 1) reinforce guidance and support, 2) fit within their lifestyle, and 3) help set future goals, particularly after witnessing the effect of their current behavior(s) on the projected physical appearance (external and internal organs) of avatars. Teens wanted 2 virtual characters: a virtual agent to act as a coach or teacher and an avatar (extension of themselves) to serve as a "buddy" for empathic support and guidance and as a surrogate for rewards. Preferred modalities for use include both mobile devices to accommodate access and desktop to accommodate preferences for maximum screen real estate to support virtualization of functions that are more contemplative and complex (e.g., goal setting). Adolescents expressed a desire for limited co-user access, which they could regulate. Data revealed certain barriers and facilitators that could affect adoption and use. DISCUSSION: The current study extends the support of teens, parents, and providers for adding avatars or virtual agents to traditional computer-based interactions. Data supports the desire for a personal relationship with a virtual character in support of previous studies. The study provides a foundation for further work in the area of avatar-driven motivational interviewing. CONCLUSIONS: This study provides evidence supporting the use of avatars and virtual agents, designed using participatory approaches, to be included in the continuum of care. Increased probability of engagement and long-term retention of overweight, obese adolescent users and suggests expanding current chronic care models toward more comprehensive, socio-technical representations.

Tanner stage 4 breast development in adults: forensic implications.

BACKGROUND AND OBJECTIVE: Forensic testimony in alleged child pornography cases commonly asserts that Tanner stage (TS) 4 breast development, characterized by secondary mounding of the areola that is obliterated in TS 5, is evidence of age <18 years. Clinical experience does not support this notion, but there are no relevant studies. We sought to estimate how frequently TS 4 might be interpreted from nonclinical images by individual forensic experts. METHOD: Published images of 547 adult women were independently examined by the authors and classified as having TS 4 or TS 5 breast development. RESULTS: There was concordance among all 4 of the examiners for 17 of the images, agreement of 3 of the examiners on another 36 images, of 2 examiners on 39 images, and 53 images were designated TS 4 by only 1 examiner, for a total of 153 (26.5%) images that could have been considered by a single forensic expert to represent TS 4. CONCLUSIONS: A substantial number of adults have persistent TS 4 breast development. This observation, and the frequent difficulty distinguishing TS 4 from TS 5, even by adolescent development specialists, especially in nonclinical images, renders testimony based on this distinction invalid. Without clinical relevance for distinguishing these advanced stages of breast development, they should both be considered indicative of full maturation. Testimony based on this inappropriate test of maturity should no longer be allowed.

Telehealth behavior therapy for the management of type 1 diabetes in adolescents.

BACKGROUND: Poor management of type 1 diabetes mellitus (T1DM) may result in serious medical complications. Psychological intervention may improve adherence to medical regimens; however, access to trained professionals is limited, particularly in rural communities. Telehealth interventions may address this by allowing families to access services at home; however, little is known about the efficacy of such services. METHOD: This study presents results from a pilot trial of a randomized waitlist controlled trial of Telehealth Behavioral Therapy (TBT) for youths with T1DM. Primary outcome measures were adherence to the diabetes regimen, glycemic control, and level of family discord. Thirty-two youths (23 female) with T1DM (aged 9 to 17 years) and one parent or caregiver participated. Telehealth Behavioral Therapy sessions were conducted thrice weekly for 12 weeks by phone and lasted an average of 15 min each. RESULTS: Results indicated that youths in treatment decreased their hemoglobin A1c by 0.74 compared to 0.09 in the waitlist, though this was not statistically significant. Youths in treatment reported increased unsupportive and decreased caring parental behaviors. CONCLUSION: Telehealth Behavioral Therapy improves access to knowledgeable providers and results in a clinically significant improvement in glycemic control. Despite some youths experiencing an increase in unsupportive parental behaviors, TBT is a promising method of service delivery that warrants further investigation.

Exploration of food addiction in pediatric patients: A preliminary investigation.

OBJECTIVES: The goals of the present study were to explore the possibility that symptoms of food addiction may exist for some children and to identify factors that may be associated with pediatric food addiction. METHODS: Participants were 50 children (aged 8-19), recruited from the Pediatric Lipid Clinic at a large southeastern teaching hospital, and their parent/guardian. Participants completed questionnaires to assess food- and eating-related attitudes and behaviors, as well as symptoms of food addiction. RESULTS: Parent- and child-reported behaviors and attitudes demonstrated similar patterns. Child BMI ratings were significantly correlated with overeating (r = .42, p = .02) and emotional eating (r = .33, p = .04). Of note, 15.2% of children indicated that they "Often," "Usually," or "Always" think that they are addicted to food, and an additional 17.4% reported that they "Sometimes" feel that way. Food addiction symptoms were significantly correlated with child overeating (r = .64, p < .001), uncontrolled eating (r = .60, p < .001), emotionol eating (r = .62, p < .001), food preoccupation (r = .58, p < .001), overconcern with body size (r = .54, p < .001), and caloric awareness and control (r = -.31, p = .04). CONCLUSIONS: Results of the present study suggest that "food addiction" may be a real problem for a subset of children who suffer from overweight/obesity. Identification of food addiction may improve obesity treatment efforts for this subset of patients.

ANALYSIS: mobile phones integrated into diabetes management: a logical progression.

In this issue of Journal of Diabetes Science and Technology, the intervention described by D. Katz, "Novel Interactive Cell-Phone Technology for Health Enhancement," uses cell phones to provide the rapid communication necessary for the support of intensive management of diabetes. Mobile technology is widely accepted in today's society and can be an effective tool for this cause. There have been numerous interventions using various communication tools, including cell phones, to manage chronic disease, which all propose that improved communication and feedback to patients would improve health status. Dr. Katz has taken the next step by giving semiautomated, real-time, immediate feedback on each data point all transmitted by cell phone.

Knowledge improvement with web-based diabetes education program: brainfood.

BACKGROUND: Health literacy has a direct effect on health outcomes, but the complexity of diabetes education and time constraints on the health care team have made delivery of this education difficult. METHODS: The Florida Initiative in Telemedicine and Education developed an education website (Brainfood) for multiple literacy levels. The site consists of 19 education units, 15 of which provided gradable test scores; a narrated cartoon provides essential information to low reading level learners. Text is presented at both 4th and 10th grade level. Literacy level of the user is not evaluated; rather, users choose their preferred format. The administrative backbone stores user demographics and test scores. Nurses can receive credit hours for completion of Brainfood, 13 tests required. Results were analyzed by a non-paired t test. RESULTS: Five hundred thirteen users have logged in to the site and clicked "I agree" on an informed consent. Of non-nurses, 145 of 389 took pre-tests (range 89-145 depending on module), and 135 took post-tests (range 84-135). For each of the 15 modules, post-test scores improved significantly (P < 0.001 by non-paired t test). Of nurses, 68 of the 124 took pre-tests (range 26-68), and up to 56 (range 24-56) took post-tests. Post-test scores improved significantly (P < 0.05 by non-paired t test) on 13 modules. Post-test scores improved, but were not statistically significant for "Nutrition 101," a module about very basic nutrition. Web-based education about Type 1 diabetes mellitus improved the knowledge level of all users. Nurses had a lower margin of improvement for most modules as they started with a higher base knowledge level. Non-nurses improved significantly on all modules from pre-test to post-test. Post-test scores for the nurses and non-nurses were indistinguishable. CONCLUSION: Brainfood, a web-based diabetes education program, is educationally sound and effective at delivering Type 1 diabetes mellitus education to both professionals and non-professionals. Web access from non-clinic settings can improve access to high-quality education for learners in remote or underserved locations.

Home-based behavioral health intervention: Use of a telehealth model to address poor adherence to type-1 diabetes medical regimens.

Youth with insulin-dependent diabetes mellitus face complex treatment regimens and often have difficulty adhering to treatment requirements. Many behavioral-health intervention strategies, such as psychoeducational groups, diabetes summer camps, individual therapy, and residential treatment have been utilized to address this issue. While some have been effective, many barriers exist that limit the number of youth who are able to utilize these treatments. Additionally, the effectiveness of these treatments does not typically generalize to the home environment. Telephone-based, intensive, behavioral-health interventions may address barriers to treatment access by providing lower cost treatment that is easier to access for youth who do not live near a knowledgeable behavioral-health specialist. Additionally, delivery via telephone enables the interventions to take place in the home. This, in combination with parental involvement in the treatment, may increase generalization of the positive treatment outcomes to the home environment. The purpose of this paper is to describe a controlled trial of a telehealth intervention for youth whose diabetes is poorly managed. Preliminary outcome data for the trial are promising. Representative cases from the trial are presented in case-study format.

Improved access to subspecialist diabetes care by telemedicine: cost savings and care measures in the first two years of the FITE diabetes project.

We have used telemedicine clinics supplemented by online education to provide effective care for children with diabetes. Before the programme began, the mean interval between visits was 149 days; in year 1 of the programme it was 98 days, and in year 2 it was 89 days. Before the programme, there were on average 13 hospitalizations a year (47 days) and this decreased to 3.5 hospitalizations a year (5.5 days). Emergency department visits decreased from 8 to 2.5 per year. On 10 occasions after the programme started, ketosis was managed by telephone intervention alone, relying on family-initiated calls. Over 90% of patients and family members expressed satisfaction with the telemedicine service and wished to continue using it. In all, 95% felt little self-consciousness. Over 90% felt their privacy was respected. The programme saved US dollar 27,860 per year. The present study demonstrated improved access to specialized health care via telemedicine in combination with online education improved health status and reduced costs by reducing hospitalizations and emergency department visits.

School nurse, family and provider connectivity in the FITE diabetes project.

The Florida Initiative in Telehealth and Education (FITE) diabetes project includes a system of remote blood glucose monitoring and online education for school personnel, families and providers. Forty-four patients with diabetes (100% of patients), six caregivers, six case managers and 18 school nurses were provided with secure email access, allowing blood glucose and other data transfer. In all, 50% of school nurses and 100% of case managers completed educational modules on the FITE Website. Over 90% of patients and all school nurses received equipment for transmitting blood glucose data to their computers. The data were discussed during clinic appointments. Inclusion of previously unavailable data from school nurses contributed to fine-tuning the diabetes management regimen. Those patients, families and school nurses who chose to transmit blood glucose data and participate in online education expressed satisfaction with the technology, the process and the improved communication.

Online diabetes education: design and evaluation with prospective diabetes camp counsellors.

An educational Website was designed by the Florida Initiative in Telehealth and Education group, and an online diabetes education test was developed using a sample of 60 children and young adults aged 8-22 years, all of whom had diabetes. The 31 items were analysed for item difficulty. Eight test items were eliminated as being unsuitable. The test was then used in 67 prospective diabetes counsellors (23 men, 44 women) who volunteered for a summer camp. Camp counsellors ranged in age from 17 to 33 years (mean 22 years, SD 3). The counsellors' mean pre-test scores were 80% and their mean post-test scores were 92%. There was a significant improvement (P=0.001) of approximately 1.25 questions from pre- to post-test. This supports the use of the online educational Website for training individuals working with children with diabetes. The Website may prove to be useful for online education in other areas of diabetes management.

Advances in telemedicine in the 21st century.

Increasing demands on practitioners' time and increasing complexity of patient education and management have created a demand for creative solutions to providing for those needs. Telemedicine can answer some of those needs. Further documentation of the efficacy and cost-effectiveness of telemedicine and education is important but should not hinder the provision of care that is required yet unavailable by traditional means.

An initial evaluation of the design of pediatric psychology consultation service with children with diabetes.

The objective of this study was to review the process of psychology consultation with an outpatient pediatric diabetes service, and provide data regarding assessment and outcome. The purpose was to demonstrate that the inclusion of psychology in the care of the child would enhance the effectiveness of treatment delivery. Over a one-year period, 91 psychological consultations were reviewed for information related to reasons for referral, diagnosis, and treatment. Processes of assessment and collaboration are described. Nearly half of all the participants that were referred for a consultation met the criteria for a psychiatric disorder, including Attention-Deficit Hyperactivity Disorder, mood disorder or anxiety. Paired t-tests revealed significant improvement in metabolic control from referral to the next clinic appointment. Psychological consultation appears to have a positive impact on selected health outcomes. Given the large number of children with psychiatric disorder, psychological intervention may facilitate adherence and reduce complications associated with poor metabolic control.

Intensive telehealth management of five at-risk adolescents with diabetes.

Five adolescents with diabetes participated in an intensive outpatient treatment programme designed to improve adherence to their regimen and improve metabolic control. Families reported blood sugar levels, injections and food intake daily by telephone. After four weeks they were offered a video-phone. Nine subjects were recruited but four of them dropped out. Of the remaining five, one subject used a video-phone and one subject reported blood sugar results by email. Most of the children improved their metabolic control and all five subjects showed reduced HbA(1c) levels during the three months of the study. The use of telehealth facilitated the treatment of adolescents with poor glycaemic control.
