14 Clinical Trials for Various Conditions
This study aims to test two strategies for weight loss. Participants will be randomly assigned to one of the two 4-week weight loss programs: (1) a behavioral weight loss program that involves recording weekly weight, physical activity, and caloric intake plus daily exercises in which information about a healthy lifestyle is reviewed or (2) a behavioral weight loss program that involves recording weekly weight, physical activity, and caloric intake plus daily exercises in which descriptions of positive future events are reviewed. Throughout the study, participants will complete assessments that examine the effects of the interventions on delay discounting, physical activity, weight, and other important health and psychosocial outcomes.
This study aims to test two strategies for weight loss maintenance. It involves two phases, a weight loss phase and a maintenance phase. During Phase I (the weight loss phase), participants will receive a 16-week, Web-based behavioral weight loss program that involves access to weekly weight loss information and weekly personalized feedback on diet, activity, and weight loss goals. Individuals who lose at least 5% of their initial body weight during this program, will be invited to participate in Phase II. During Phase II, two 4-month treatments for weight loss maintenance will be tested. At the beginning of Phase II, participants will be randomly assigned to one of the two maintenance programs: (1) a behavioral maintenance program that involves in-person group meetings plus daily exercises in which information about a healthy lifestyle is reviewed or (2) a behavioral maintenance program that involves in-person group meetings plus daily exercises in which descriptions of positive future events are reviewed. Throughout the study, participants will complete assessments that examine the effects of the interventions on delay discounting, physical activity, weight, and other important health and psychosocial outcomes.
This study will test a website for teens designed to help them improve both diet and physical activity. The website will have several components: educational messages, role model stories, goal setting, self-monitoring forms, problem solving, a monitored discussion forum, and diet and physical activity (PA) assessment questionnaires.
The study seeks to discover whether peer rejection increases the value of food relative to peer interaction in overweight individuals. After playing a computer game that randomly simulates peer rejection or peer acceptance, participants will play another computer game that will assess the value of food and social interactions. Overweight individuals may be more likely to resort to food in moments of distress and less likely to choose to interact with a peer to reestablish their sense of belongingness.
Study of activity choices after playing a computer game.
This study examines the effects of increasing the cost of social interactions and food on overweight and non-overweight youth. Using a computerized operant task youth will earn points exchangeable for food and social activity. The investigators predict that both overweight and non-overweight children will substitute food for interactions with an unfamiliar peer when this alternative is made expensive. Also, the investigators predict that both overweight and lean participants will defend their choice to spend time with a friend even when this alternative is made expensive.
Cardiovascular disease, the number one leading cause of death in the United States, is highly prevalent in cancer survivors. Physical activity can reduce risk, and referrals to programs addressing survivors' choices are highly recommended from providers in cancer survivorship, though rarely implemented. The study team proposes to develop ActivityChoice, a clinic-based implementation program, using patient narrative decision aids to support choices to a group in-person, group virtual, or self-monitored digital health physical activity program.
The study will test the effectiveness and examine the sustained effects of weekly programming on enhancing (1) lifestyle behaviors (physical activity, dietary intake, use of technology, amount of sleep), (2) self-efficacy, (3) self-esteem, and (4) readiness to change among children ages 8-11 years.
College students are in a newly independent phase of life; many of whom encounter unhealthy dietary decision- making, barriers to physical activity, and poor sleep behaviors. Healthy Detours is a location-based smartphone application tailored in real-time to a student's schedule and locale, and aims to guide students toward healthier eating, exercise, and lifestyle choices as a way to prevent the onset of damaging and costly health outcomes. Through a randomized control trial, this Phase II project will test the effectiveness of an evidence-based smartphone application that will provide students with on-demand, location-specific information about healthy lifestyle choices.
CHOICES is a program to provide children and families with lifetime tools and lifestyle strategies to achieve and maintain a healthy body size. Both parents and children get active, learn about the food choices they can make, and about the roles of TV in their lives. Led by physicians and young adults, the 12 weekly 90 minute sessions provide hands on experiences that connect into the participants' daily lives. In the study, the families were divided into two groups, beginning their classes 6 months apart. Body measurements were taken at baseline and every 4 months to 16 months.
The purpose of this study is to determine whether playing motion-controlled video games produces low caloric intake and higher caloric expenditure than watching TV or playing traditional video games.
The average adult has a poor quality diet and sedentary lifestyle, but the best way to produce sustained healthy change remains unknown. The MBC2 intervention uses handheld technology to help individuals monitor and transmit information about their eating and activity remotely to a behavior coach. The proposed trial tests whether MBC2 intervention improves diet and activity more than a stress management control condition, and whether changing multiple health behaviors is best achieved by changing them all at the same time, or one after another.
The increasing prevalence of obesity in U.S. children and adolescents is a major health threat to our society, especially among minority and low social economic status (SES) populations. During adolescence physical activity (PA) decreases and is likely an important contributor to the increasing trend in childhood obesity rates. Little evidence suggests that school-based curriculum interventions lead to increases in overall PA. Thus, this proposal will evaluate the efficacy of an innovative motivational and behavioral skills after-school program for promoting increases PA among underserved adolescents (e.g., minorities, low SES). The motivational plus behavioral skills intervention is consistent with Self-Determination (Motivation) Theory and Social Cognitive Theory in that it emphasizes increasing intrinsic motivation and behavioral skills for PA. Adolescents in the intervention take part in developing the program, selecting physical activities that generate fun and interest, and generating their own coping strategies for making effective PA changes during a videotaped session. Preliminary data from our group demonstrates the feasibility of the motivational plus behavioral skills PA program for increasing moderate-to-vigorous PA (MVPA) in underserved adolescents in South Carolina. The proposed project will use a school-based nested cohort design to evaluate efficacy of a 17-week motivational plus behavioral skills program versus typical after-school program (general health education only) on increasing PA in underserved adolescents. Twenty-four middle schools (70 6th graders per school; N=1,680), located in South Carolina will be randomly assigned to one of two after-school programs. The study employs a nested cohort design, with schools, rather than individuals assigned to condition and will be analyzed using repeated measures analysis of covariance techniques as outlined by Murray. We will also examine psychosocial variables (PA self-efficacy, self-concept, motivation, social support, and enjoyment) as potential mediators of the intervention on changes in MVPA using regression and structural equation modeling techniques. This study will address an important public health problem that will have implications for decreasing obesity in underserved adolescents.
CREATION Health encompasses eight whole-person care principles: Choice, Rest, Environment, Activity, Trust, Interpersonal-Relationships, Outlook, and Nutrition. An existing initial tool consisting of 74 items related to the eight CREATION Health principles and college students' wellbeing were generated by subject/methodology experts. To develop the CREATION Health Assessment Tool for College Students (CHAT-CS), this initial tool needs to be finalized through item reductions and validations in the population of college students.
