Rigorous Evaluation of Let's Talk Birth Control

The goal of this cluster-level randomized controlled trial is to evaluate the impacts of Let's Talk Birth Control, a clinical decision support intervention for adolescents that consists of a printed contraceptive decision aid (CDA), contraceptive counseling, and a QR code to the Bedsider.org Method Explorer (ME). The goal of Let's Talk Birth Control is to reduce rates of sex without a contraceptive method among adolescent patients, increase use of preferred contraceptive method, as well as to increase self-efficacy to discuss, obtain, and correctly use contraceptive methods The primary research questions are: * Does receiving care from a health center participating in Let's Talk Birth Control reduce rates of sex without a contraceptive method among adolescent patients compared to those visiting a standard of care control health center? * Does receiving care from a health center participating in Let's Talk Birth Control increase use of preferred contraceptive method among adolescent patients compared to those visiting a standard of care control health center? The evaluation will focus on the impacts of receiving the Let's Talk Birth Control intervention, as compared to receiving standard health care services. As part of this study: * All participants will be asked to complete baseline, 1-week post-intervention, and 9-month follow-up surveys. * Participants at health centers randomized to receive the Let's Talk intervention, will be asked to: * Review the Let's Talk CDA independently prior to meeting with their healthcare provider * Participate in an observation focused on the provider's use of the CDA for contraceptive counseling during the healthcare visit (select participants only) * Participate in a focus group discussing their perceptions of the Let's Talk Birth Control intervention (select participants only) Staff at health centers randomized to receive the Let's Talk intervention will be asked to: * Complete a 45-60 minute online asynchronous training covering patient-centered contraceptive counseling (PCCC) for adolescents and using the CDA * Use the Let's Talk CDA to facilitate patient-centered contraceptive counseling with patients that have enrolled in the study

Psychiatric Care and Education for Adolescents and Young Adults in the Ile-de-France Region: Expectations and Experiences of Young People and Parents Concerned

Most chronic psychiatric disorders begin before the age of 18. In the most severe cases, prolonged hospitalization is essential, but this ultimately leads to harmful school dropout and social exclusion. "Care-study" hospitalizations offer comprehensive psychiatric, educational, and social care to prevent this. However, these programs have been largely under-evaluated ; only one limited and very old study has looked at the perspective of the young people concerned, and none at all has looked at their parents. Today, however, PREMS (Patient-Reported Experience Measures), which assess how users experience care (satisfaction, subjective and objective experiences, relationships with caregivers), are important indicators for improving care systems. the investigators therefore wish to gather young people's expectations regarding healthcare and education, as well as their opinions and those of their parents on their experiences in the current context, in order to evaluate and improve these systems by better meeting the expectations and needs of users.

Intervention-Induced Plasticity of Flexibility and Learning Mechanisms in ASD

This project explores the association between learning and cognitive flexibility by testing whether a cognitive behavioral intervention designed to improve flexibility in ASD changes learning and associated neural activation using model-based functional magnetic resonance imaging (m-fMRI). The study proposes that variability in learning mechanisms is associated with behavioral flexibility and explains differences in adaptive and treatment outcomes. The study employs a longitudinal case-controlled design in 60 14-18 year old youth with ASD at 3 time-points 8 months apart, each including m-fMRI during learning and behavioral measurement of executive and adaptive function. Aim 1 tests the hypothesis that individual variation in learning biases and their neural correlates predicts behavioral flexibility and is stable over time. Aim 2 tests plasticity of learning mechanisms induced by a cognitive-behavioral intervention for flexibility. Aim 3 tests hypothesis about intervention-induced plasticity of neural functional connectivity.

Using Mentalization Based Therapy to Support Children and Adolescents Referred to Specialist Mental Health Services in the NHS for Aggressive and/or Violent Behaviour

The MICA Study is a research project that has been designed to work out how helpful mentalisation based therapy is. This is a new type of support that helps young people make sense of their own behaviours and feelings, and those of others. It involves meeting regularly with a mental health practitioner and parents/carers can be involved in some meetings too. It is hoped that this new type of support will help young people stop acting aggressively/violently. This project will be delivered in Forensic Child and Adolescent Mental Health Services (FCAMHS) in England. This service supports some of the most vulnerable young people in the country, who may also have involvement from other professionals including the Youth Justice System. The aim of the research is to make the support better for young people who use these services. This research involves doing a randomised controlled trial. This means half the young people will get the usual support from FCAMHS, and half will get the usual support plus the new support. The results will be used to compare mentalisation based therapy to the support FCAMHS usually provides. This will show the best way to support young people with their aggressive/violent behaviours. To start with, young people will answer a questionnaire. Following this, young people will receive either usual support or usual support plus MBT for six months. After this, young people will answer a questionnaire again. Some young people will be asked to take part in an optional interview to share their thoughts on this research. All young people aged 10-17 years who have been referred to a FCAMHS in England will be asked to take part, as long as they can speak and understand English. Some young people might not want to take part in this research and that will not change the support they receive.

ChangeGradients: Promoting Adolescent Health Behavior Change

As most adolescents visit a healthcare provider once a year, health behavior change interventions linked to clinic-based health information technologies hold significant promise for improving healthcare quality and subsequent behavioral health outcomes for adolescents (Baird, 2014, Harris, 2017). Recognizing the potential to leverage recent advances in machine learning and interactive narrative environments, the investigators are now well positioned to design health behavior change systems that extend the reach of clinicians to realize significant impacts on behavior change for adolescent preventive health. The proposed project centers on the design, development, and evaluation of a clinically-integrated health behavior change system for adolescents. CHANGEGRADIENTS will introduce an innovative reinforcement learning-based feedback loop in which adolescent patients interact with personalized behavior change interactive narratives that are dynamically personalized and realized in a rich narrative-centered virtual environment. CHANGEGRADIENTS will iteratively improve its behavior change models using policy gradient methods for Reinforcement Learning (RL) designed to optimize adolescents' achieved behavior change outcomes. This in turn will enable CHANGEGRADIENTS to generate more effective behavior change narratives, which will then lead to further improved behavior change outcomes. With a focus on risky behaviors and an emphasis on alcohol use, adolescents will interact with CHANGEGRADIENTS to develop an experiential understanding of the dynamics and consequences of their alcohol use decisions. The proposed project holds significant transformative potential for (1) producing theoretical and practical advances in how to realize significant impacts on adolescent health behavior change through novel interactive narrative technologies integrated with policy-based reinforcement learning, (2) devising sample-efficient policy gradient methods for RL that produce personalized behavior change experiences by integrating theoretically based models of health behavior change with data-driven models of interactive narrative generation, and (3) promoting new models for integrating personalized health behavior change technologies into clinical care that extend the effective reach of clinicians.

A Randomized Clinical Trial of a Novel Drug Education and Diversion Program (iDECIDE) for Middle and High School Students

The primary goal of this study is to test the effectiveness of the iDECIDE (Drug Education Curriculum: Intervention, Diversion, and Empowerment) curriculum, a novel drug education and diversion program, in approximately 300 middle and high school students, who have violated their school substance use policies in the past month, as an alternative to punitive school responses for school-based substance use infractions. This randomized controlled trial will test the hypothesis that adolescents randomized to the iDECIDE curriculum will have improved substance use outcomes (i.e., knowledge, attitudes, and behavior) compared to adolescents in a waitlist control group. The outcomes of this study will measure knowledge of drug effects and brain development, perceptions of harm from substance use, willingness to quit or reduce use, and substance use behavior.

Evaluation of the Close to Home Program in California

Investigators propose to rigorously evaluate the Close to Home (C2H) model via a cluster-matched control trial across 18 diverse communities (9 C2H, 9 control) in California via collection and analyses of social network, school-based and social media data. Close to Home is a primary prevention community mobilization model implemented in 10 communities across California that engages community members across multiple sectors and social networks to strengthen community connections and shift social norms regarding sexual violence (SV), but has never been rigorously evaluated. C2H moves beyond criminal justice, lobbying, or school-based curricular approaches, taking a true community-level and community-led approach. This is a five-year project, funded by the Centers for Disease Control and Prevention (CDC) for 3 years with competitive awards for years 4 and 5, and is conducted in partnership with the California Department of Public Health (CDPH) and ValorUs (formerly CALCASA). The University of California, San Diego (UCSD) and CDPH partnership is uniquely poised to conduct the first rigorous evaluation of C2H in California at this time.

Mental Health and Sexuality in Adolescents and Young Adults

According to the World Health Organization (WHO), "Sexual health is a state of physical, emotional, mental and social well-being in relation to sexuality, not merely the absence of disease, dysfunction or of infirmity. Sexual health requires a positive and respectful approach to sexuality and sexual relationships \[...\]". The main objective is to show that a training intervention intended for psychiatric care teams and targeted on the question of the impact of psychiatric disorders and psychotropic drugs on the sexuality of young people, increases the proportion of young people with whom the question of sexual health is discussed (in connection with psychiatric disorders and, if applicable, with the taking of psychotropic treatment, while they are hospitalized for a psychiatric disorder in the clinics of the FSEF and receive, or not, psychotropic treatment ).
