  • Healthy weight regulation and eating disorder prevention in high school students: a universal and targeted web-based intervention. Journal of medical Internet research Jones, M., Taylor Lynch, K., Kass, A. E., Burrows, A., Williams, J., Wilfley, D. E., Taylor, C. B. 2014; 16 (2)

    Abstract

    Given the rising rates of obesity in children and adolescents, developing evidence-based weight loss or weight maintenance interventions that can be widely disseminated, well implemented, and are highly scalable is a public health necessity. Such interventions should ensure that adolescents establish healthy weight regulation practices while also reducing eating disorder risk.This study describes an online program, StayingFit, which has two tracks for universal and targeted delivery and was designed to enhance healthy living skills, encourage healthy weight regulation, and improve weight/shape concerns among high school adolescents.Ninth grade students in two high schools in the San Francisco Bay area and in St Louis were invited to participate. Students who were overweight (body mass index [BMI] >85th percentile) were offered the weight management track of StayingFit; students who were normal weight were offered the healthy habits track. The 12-session program included a monitored discussion group and interactive self-monitoring logs. Measures completed pre- and post-intervention included self-report height and weight, used to calculate BMI percentile for age and sex and standardized BMI (zBMI), Youth Risk Behavior Survey (YRBS) nutrition data, the Weight Concerns Scale, and the Center for Epidemiological Studies Depression Scale.A total of 336 students provided informed consent and were included in the analyses. The racial breakdown of the sample was as follows: 46.7% (157/336) multiracial/other, 31.0% (104/336) Caucasian, 16.7% (56/336) African American, and 5.7% (19/336) did not specify; 43.5% (146/336) of students identified as Hispanic/Latino. BMI percentile and zBMI significantly decreased among students in the weight management track. BMI percentile and zBMI did not significantly change among students in the healthy habits track, demonstrating that these students maintained their weight. Weight/shape concerns significantly decreased among participants in both tracks who had elevated weight/shape concerns at baseline. Fruit and vegetable consumption increased for both tracks. Physical activity increased among participants in the weight management track, while soda consumption and television time decreased.Results suggest that an Internet-based, universally delivered, targeted intervention may support healthy weight regulation, improve weight/shape concerns among participants with eating disorders risk, and increase physical activity in high school students. Tailored content and interactive features to encourage behavior change may lead to sustainable improvements in adolescent health.

  • Designing virtual environments to measure behavioral correlates of state-level body satisfaction. Studies in health technology and informatics Purvis, C. K., Jones, M., Bailey, J., Bailenson, J., Taylor, C. B. 2013; 191: 168-172

    Abstract

    Virtual reality (VR) offers a unique method for eliciting state-variable fluctuations in body satisfaction and associated behaviors by allowing near-perfect control over environmental factors. Greater variability in momentary body satisfaction is associated with more problematic eating behavior and cognitive styles predictive of eating disorders. The field currently lacks a model for understanding environmental variables and everyday events that tend to influence fluctuations in state body satisfaction. This study proposes a model of state-level body satisfaction and presents a method for measuring changes as they occur. We aim to investigate body comparison, selective attention and body checking behaviors in relation to self-report levels of state body satisfaction. We additionally assess interpersonal correlates of state body satisfaction using VR to measure personal distance between subjects and avatars of varying body sizes. 80 female college students with varying levels of weight and shape concerns will be exposed to five virtual environments designed to elicit varying levels of body dissatisfaction: (a) an empty room; (b) an empty beach; (c) a beach populated with avatars; (d) an empty party scene; (e) a party scene populated with avatars. Self-report body satisfaction was measured immediately following each exposure. A tracking system automatically tracked subjects' head orientation and body translation to measure visual gaze and personal space behavior relative to each virtual human within the environment. Data collection is currently underway and expected to be completed by May 2013. Preliminary data and development of the VR model for state-variable assessment will be presented.

  • Family-based Early Intervention for Anorexia Nervosa EUROPEAN EATING DISORDERS REVIEW Jones, M., Voelker, U., Lock, J., Taylor, C. B., Jacobi, C. 2012; 20 (3): e137-e143

    Abstract

    This study explores whether potential risk factors for anorexia nervosa (AN) can be modified by a family-based Internet-facilitated intervention and examines the feasibility, acceptability, and short-term efficacy of the Parents Act Now programme in the USA and Germany.Forty-six girls aged 11-17 were studied during a 12-month period and evaluated at screening, baseline, and post-intervention. Parents participated in the six-week intervention.Twenty-four per cent of girls (n?=?791) screened met the risk criteria for AN. Parents accessed the majority of the online sessions and rated the programme favourably. At post-assessment, 16 of 19 participants evidenced reduced risk status. Participants remained stable or increased in ideal body weight and reported decreased eating disorder attitudes and behaviours.Results suggest that an easily disseminated, brief, online programme with minimal therapist support is feasible, accepted favourably by parents, and may be beneficial for prevention of exacerbation of AN pathology.

  • Psychological and Behavioral Correlates of Excess Weight: Misperception of Obese Status Among Persons with Class II Obesity INTERNATIONAL JOURNAL OF EATING DISORDERS Jones, M., Grilo, C. M., Masheb, R. M., White, M. A. 2010; 43 (7): 628-632

    Abstract

    This study examined psychological and behavioral correlates of weight status perception in 173 Class II obese adult community volunteers.Participants completed the Eating Disorder Examination-Self-Report (EDE-Q), Three Factor Eating Questionnaire (TFEQ), Beck Depression Inventory, and Rosenberg Self-Esteem Scale online. Key items assessed dieting frequency, weight history, and perceived current weight status (normal weight, overweight, or obese). Actual weight status was determined using NIDDK/CDC classification schemes.Among participants with Class II obesity, 50.9% incorrectly classified their weight as overweight versus obese, whereas 49.1% accurately perceived their weight status as obese. Inaccurate participants reported significantly less binge eating and less eating disorder psychopathology. Despite similar BMI, inaccurate participants reported less distress regarding overeating and loss of control over eating.Our findings suggest that obesity status underestimation is associated with less eating disorder psychopathology. Underestimation of obesity status may exacerbate risk for negative health consequences because of a failure to recognize and respond to excess weight.

  • The clinical significance of loss of control over eating in overweight adolescents INTERNATIONAL JOURNAL OF EATING DISORDERS Goldschmidt, A. B., Jones, M., Manwaring, J. L., Luce, K. H., Osborne, M. I., Cunning, D., Taylor, K. L., Doyle, A. C., Wilfley, D. E., Taylor, C. B. 2008; 41 (2): 153-158

    Abstract

    Given limited data on the diagnostic validity of binge eating disorder (BED) in adolescents, this study sought to characterize overweight adolescents according to types of overeating episodes.Ninety-six adolescents (ages 13-17 years) with recurrent binge eating (BE), loss of control with or without overeating (subclinical BE; SUB), overeating without loss of control (OE), and no overeating or loss of control episodes (CONTROL) were compared on weight/shape concerns and depressive symptoms using ANCOVA and post-hoc least squares difference tests.BE and SUB adolescents had higher weight/shape concern scores than OEs and CONTROLs (ps < .01). BE and SUB adolescents had higher depression scores than CONTROL adolescents (ps < .05). BE adolescents had greater depression scores than OE (p < .01) but not SUB adolescents.Loss of control over eating signals increased impairment independent of overeating in adolescents. Results support refining BED criteria for youth to reflect this distinction.

  • Randomized, controlled trial of an internet-facilitated intervention for reducing binge eating and overweight in adolescents PEDIATRICS Jones, M., Luce, K. H., Osborne, M. I., Taylor, K., Cunning, D., Doyle, A. C., Wilfley, D. E., Taylor, C. B. 2008; 121 (3): 453-462

    Abstract

    This study examined the efficacy of an Internet-facilitated intervention for weight maintenance and binge eating in adolescents.A total of 105 adolescent male and female high school students at risk for overweight (mean age: 15.1 +/- 1.0 years) were randomly assigned to a 16-week online intervention, StudentBodies2-BED (n = 52), or the wait-list control group (n = 53).Participants in the StudentBodies2-BED group had significantly lower BMI z scores and BMI from baseline assessment to follow-up assessment, compared with the wait-list control group. In addition, significant reductions in objective binge episodes and subjective binge episodes from baseline assessment to posttreatment assessment and from baseline assessment to follow-up assessment were observed among StudentBodies2-BED participants. The StudentBodies2-BED group also reported significantly reduced weight and shape concerns from posttreatment assessment to follow-up assessment and from baseline assessment to follow-up assessment. Participants in the StudentBodies2-BED group who engaged in objective overeating or binge eating episodes at baseline assessment experienced a significantly greater reduction in BMI at follow-up assessment, compared with the wait-list control group.Results suggest that an Internet-facilitated intervention is moderately effective in short-term weight loss and weight maintenance and yields a large reduction in binge eating. This study also demonstrates that weight management and reduction of eating disorder psychopathological features can be achieved simultaneously by using an easily disseminated, Internet-facilitated program.
