Filter by:This longitudinal experimental study tested the effects of three brief interventions: (1) prompting the formation of plans (or implementation intentions), (2) prompting self-efficacy beliefs, and (3) prompting planning + self-efficacy in adolescents aged 14-18 years relative to an active 'education only' control group. It was hypothesized that participants assigned to the interventions would exhibit a smaller increase in body fat at 14-month follow-up compared to controls. The study also investigated whether the combined planning + self-efficacy intervention would have larger effects on the main outcome (body fat) than single-component interventions. Second, it was hypothesized that the effects of the intervention conditions on body fat at 14-month follow-up would be mediated by their respective psychological and behavioral constructs: self-efficacy and planning at T2 (Mediator 1), and by moderate-to-vigorous physical activity (MVPA) at T3 (Mediator 2). It was expected that the effects of the interventions including the planning component (i.e., planning intervention and self-efficacy + planning intervention) would be mediated by respective cognitions, i.e. planning, whereas the effects of the interventions including self-efficacy component (i.e., self-efficacy intervention and self-efficacy + planning intervention) would be mediated by self-efficacy. Finally, it was explored whether the effects of the intervention (both direct and indirect effects, via their respective psychological variables and MVPA) on body fat would be moderated by the presence of built PA facilities, located in the proximity of schools.
The objective of this study is to design and evaluate an internet-based educational strategy to prevent sexual risk behaviors in Mexican adolescents. Methods: A field trial with one intervention and one comparison group, with ex-ante and ex-post measurements will be conducted in 2 public secondary schools. Adolescents between 14 and 15 years of age will participate. The intervention will be conducted in one school and the other school will serve as a comparison group, where investigators will observe the usual sexual education that the school provides. The intervention will be delivered through an internet web page; it includes four educational sessions that will be provided during a four-week period. The follow up will last three-months. The information on the study variables will be obtained through an internet-based self-applied questionnaire and collected on three occasions: when the adolescents enters to the study (baseline), once intervention is completed (at one month) and after three months of follow-up (at fourth month).
This study evaluates the short- and long-term effects on psychological wellbeing and health-related behaviours of the updated version of a universal school-based program called Diario della Salute (DDS-2) in Italian students aged 11-13 years.
Preliminary data from the investigators' National Center for Complementary and Alternative Medicine (NCCAM)-funded R21 on mindfulness-based stress reduction (MBSR) in HIV-infected youth suggest an association between mindfulness and improved self-regulation and medication adherence. This randomized, controlled trial will help the investigators to better understand the specific impact of MBSR on HIV medication and treatment adherence in HIV-infected youth, and the efficacy of MBSR in the amelioration of stress and improved self-regulation.
The number of persons actively waiting on the national solid organ waiting list continues to rise while the number donating organs has failed to keep pace. This is a particular problem for some portions of northeastern Ohio where the donation rate is as low as 32%. Adolescents are an important group for organ donation efforts as they have not yet applied for a driver's license and represent the majority of future donors. Yet many organ donation interventions have not targeted adolescents. The investigators propose to utilize existing high school teen summits developed by our Consortium partners to evaluate the effectiveness of existing donation interventions. Together, the investigators will conduct a randomized controlled 2x2 factorial trial to evaluate the independent and combined effects of two donor education interventions on consent for organ donation on the electronic Ohio Donor Registry. One thousand six hundred students over the age of 15.5 years from Cleveland-area high schools will be enrolled.
The purpose of this study is to have girls play new computer games designed for middle school children and not yet available to the public. The investigator wants to know what girls think about these games. The investigator also wants to learn about the health behavior of 7th grade girls of Hispanic/Brazilian/Latino origin, and the investigators want to test the Mighty Girls program in Miami. Half of the girls in JUEGA will be given the Mighty Girls program and the investigators want to know if this program reduces behavior that puts girls at risk for having sex, drinking, and using drugs. The program tries to reduce this risk by helping girls learn skills to make wise choices, even when their friends have other ideas or want them to make more risky choices This goal is important because US statistics indicate that Hispanic teens are at risk for teen pregnancy and Miami has one of the highest HIV and AIDS rates in the United States. The investigator wants to find out whether the Mighty Girls program is as effective in Miami-Dade County Public Schools as it was when tested in one of Orlando's Orange County Public Schools.
The primary objective is to conduct a pilot study to determine the efficacy of evidence-based interventions delivered in primary care clinic settings on parent-teen health communication.
Arizona has created a pilot program for juvenile probationers called Juveniles under Supervision and Treatment (JUST), which includes swift and certain, but modest responses, to technical violations of the terms of juvenile probation. JUST targets high- and medium-risk juvenile probationers and its stated objective is to reduce violations and overall incarceration of youth in the program. The JUST pilot is being implemented under the authority of the Arizona Governor's Office for Children, Youth and Families (GOCYF) and the Administrative Office of the Courts (AOC).
Background: Interventions on lifestyle among adolescents are important, but the main mechanisms that explain the changes (mediating variables) on lifestyle have been little explored. Investigators present the rationale and methods of a cluster-randomized controlled trial aimed to promote promotion active and healthy lifestyle (especially physical activity [PA] practice and reducing screen time use) among Brazilian students - the "Fortaleça sua Saúde" ("Strengthen Your Health" in Portuguese) program. Methods/Design: This is a school-based cluster-randomized controlled trial that included students from six elementary full-time public schools (7-9 grades) in Fortaleza, northeastern Brazil. The intervention duration was one academic semester (approximately four months) in 2014. The intervention strategies focused on teachers' training and activities on health in curriculum (including a specific training to Physical Education teachers), active opportunities in the school environment (availability of spaces and materials for PA) and health education (production and exhibition of health material at school, and distributing pamphlets to patients). Data collection will be performed before and immediately after 4 months of intervention. The primary variables include the practice of PA (weekly PA volume) and the screen time use (TV/computer/video games). Intrapersonal, interpersonal and environmental variables associated to PA and screen time use will be evaluated by standardized questionnaire. Other components of the lifestyle (e.g., eating habits), psychological (e.g., self-rated health, body satisfaction), biological (general and abdominal obesity) and academic performance will be also evaluated in the patients. Depressive symptoms, eating disorders, sleep quality, objectively-measured physical activity will be evaluated in obese patients. Discussion: Is effective, this program will contribute to the development of public policies for active and health lifestyle promotion among young population, especially from low- and middle-income countries. The main variables (intrapersonal, interpersonal and/or environmental stimulus) that help the young people to adopt an active lifestyle also may be indicated. Finally, investigators expect that the proposed strategies may be adaptable to the public school reality and they may be extended to the entire school system.
The primary objective of this protocol is to test whether an activity monitor with an online motivational rewards component will increase physical activity levels of middle school-aged students. The secondary objective is to learn about the functionality and utilization of the activity meter device among this age group.
