26 Clinical Trials for Various Conditions
The goal of this study is to investigate the role of social factors on speech learning, including production and perception, in infants ranging in age from \~7-18 months. Infants have either typical hearing or sensorineural hearing loss. The main prediction of the study is that social reinforcement will engender improvements in vocal learning above and beyond gains in hearing in infants with hearing loss. As part of this study: * The parent and infant engage in a free play session in the playroom while the investigator cues the parent to say simple nonsense words; * Infants hear playback of the same words during a second phase.
This experiment will explore the joint effects of social information, social support, associative learning, and oxytocin on the development of placebo analgesia. The investigators predict that socially transmitted placebo effects will be enhanced by nasal administration of oxytocin, whereas associative learning effects on pain will not be altered by this pharmacological manipulation
The purpose of this study is to assess the effects of peer influences on snack purchases in adolescents. During the session teens will be given a certain amount of money to use to purchase foods and beverages in a hypothetical convenience store setting. The investigators hypothesize that overweight youth will be less responsive to own-price elasticity for high calorie foods and less likely to show cross price elasticity for low calorie foods when the price of the high calorie for nutrient foods increases. The investigators also predict that overweight youth will show more cross price elasticity for low calorie foods when in the presence of peers; whereas lean youth's food purchases and price sensitivity will not be affected by the presence of peers.
This study aims to assess the impact of social influence on direct neural recordings in human patients undergoing surgical treatment of epilepsy. 24 patients recruited from the Epilepsy Center at Dartmouth Health Medical Center (DHMC) will undergo electrode implantation throughout the brain to localize epileptogenic zones. Patients will be asked to rate their provider's warmth, competence, and other, similar traits associated with care-competency. They will then complete the picture-induced fear and math portions of the multimodal negative affect task (MNAT) during which iEEG is recorded.
This study has two goals: 1) to test an approach to helping women who use intrauterine contraception (IUC) spread the word about this type of long-lasting, highly effective birth control method among their friends and family and; 2) to test ways of getting in touch with these women's friends and family so that investigators can track whether this approach is effective at spreading birth control information through social groups.

The objective of this study is to directly compare the effects of parents and friends on overweight and non-overweight children and adolescents' food intake and food selection using a cross-sectional design. Overweight and non-overweight children (5-6 year-old) and adolescents (13-14 year-old) will share a meal with a friend and with a parent on separate occasions. Participants' food selection and the amount of food they consumed will be compared across conditions. Hypothesis 1: The investigators hypothesize that overweight children and adolescents will select more unhealthy food items and eat more in the presence of an overweight friend than when eating with a lean friend; whereas lean participants eating with an overweight friend will eat a similar amount of food than lean youth eating with a lean friend. Hypothesis 2: The investigators predict that overweight children and adolescents (but not lean children and teens) will consume more food in the presence of their mother than in the presence of a friend. Hypothesis 3: The investigators also predict that overweight youth's energy intake will be related to parental prompts. Hypothesis 4: The investigators expect greater similarities in terms of food selection and food intake between adolescents and their friend than between adolescents and their parent.
Participants will be matched with either their friend or an unfamiliar peer who is the same gender and about the same age. Participants will have 45 minutes of free-play in an experimental room where they will have free access to energy-dense and nutrient-dense foods and an assortment of games and puzzles. The investigators predict that participants eating with a friend will eat significantly more than participants eating with an unfamiliar peer. The investigators also predict that overweight participants eating with an overweight partner will eat significantly more than participants eating with a non overweight participant.
This study, conducted at the University of Massachusetts at Amherst, will examine how male teenage driving performance varies in the presence or absence of male teenage passengers. It will explore what information teen drivers and their passengers use when making decisions that affect their performance on the road. Male drivers under 18 years of age who have a Junior Operator's or Full License and have driven at least once in the month before enrolling in the study may be eligible to participate. In a university laboratory, participants sit in a 1995 Saturn sedan and operate the controls of the car just as they would those of any other car, during simulated drives in urban, suburban and rural areas. They are fitted with a head-mounted eye tracker that records their point of gaze in real time. On one drive, the subject drives alone; on another, a male passenger rides along. After the drives, the subject fills out some questionnaires.
Community based interventions are more acceptable to community members when all participants receive the intervention. A 'stepped-wedge' or 'multiple-baseline' design allows for all participants to receive the intervention by randomizing participants into conditions defined by the length of the baseline period. The primary aim of this pilot study is to gather data that will allow the researchers to estimate parameters, such as the appropriate length of the baseline period that will allow them to power a larger study. A second key aim is to determine if a smartphone intervention that is delivered to parents can increase physical activity in their 6-10 year old inactive children.
The goal of this study is to learn why some black and Latino men and women choose not to exercise very often. Researchers also want to learn more about any social and environmental factors that may affect the way an exercise program is followed.
HPTN 096 is a community-randomized, controlled, hybrid-type III implementation effectiveness study. It is designed to evaluate an integrated strategy approach to increase the uptake and use of pre-exposure prophylaxis (PrEP) and viral suppression rates among Black MSM in the southern United States. A status-neutral approach will be taken such that Black MSM, regardless of HIV status (both those living with and without HIV), will be included in the study.
The purpose of the study is to improve patient-physician communication and clinical decisions in the context of serious illness that may affect important clinical outcomes. The investigators will examine how variations in communication patterns and clinical decisions are affected by patient demographics (e.g age, sex), patient interactional style (e.g. communication behaviors) and physician characteristics (e.g. attitudes, background, training).
This study will explore the influence of social and environmental factors, such as stress, nutrition, health status, etc., on women's reproductive function. Married Mayan women 16-42 years of age who live in the rural highlands of Guatemala and who have given birth to at least one child are eligible to participate in this study. Participants are interviewed about their demographic, social, family, personal, health, reproductive and economic situations. They have saliva and urine samples collected three times a week for up to 1 year. Their nutritional and health status is assessed monthly.
This is a randomized trial to examine the influence of number of "likes"on social media food ads on Black and White adolescents' food purchases
This exploratory experiment is designed to determine the extent to which the socialization experiences and social, behavioral, and linguistic skills of preschoolers with language impairment (LI) can be improved. The investigators implement a peer-mediated intervention in inclusive preschool classrooms, randomly assigned to treatment (n=12) or control (n=13) conditions. A focal child is identified in each classroom, representing a child with LI (3 to 5 years of age) who exhibits the poorest pragmatic-language skills and highest level of social exclusion in the classroom. Over a 12-week period, the focal children will receive peer-mediated intervention from identified peers, who use strategies to engage the focal child socially during center time, as supported by a classroom facilitator (teacher, aide). Outcomes of interest include the overarching classroom social network and its embedded socialization processes (e.g., frequency of child-to-child interaction), the focal child's interactions with peers and exposure to peer talk, and the focal child's social, behavioral, and linguistic skills. The study employs state-of-the-art social network analyses to represent the classroom network at the child, dyad, and network level and is dynamically modeled over the academic year using advanced location-tracking technologies and voice-activated recorders to capture incoming and outgoing peer talk for the focal child. The investigators anticipate the results of this study to yield significant theoretical and scientific impact. Theoretically, the investigators propose that improved socialization experiences in the preschool classroom can disrupt the social exclusion and peer maltreatment experienced by children with LI, leading to accelerated growth in linguistic, social, and behavioral outcomes for children with LI.
The purpose of this study is to help understand how attention processes influence brain engagement during emotion and social cognition. The investigators also want to know if these processes are associated with drinking alcohol. Participation includes three study visits of about 2 hours each over approximately a month. The first visit involves a magnetic resonance imaging (MRI) scan and answering survey questions. Each of the next two visits will involve a session of transcranial magnetic stimulation (TMS, a non-invasive brain stimulation technique) followed by another MRI scan. People in the Auburn/Opelika area 19 or older are eligible to participate. People who drink alcohol and people who do not drink or don't drink very much are invited to participate.
Antigen self-testing kits are more available at this stage in the pandemic, but among vulnerable populations, use is still low and instructions for antigen testing are not typically designed for low health literacy populations. Studies are needed to explore access and use of antigen tests among vulnerable populations and examine if low-health-literacy-designed interventions improve COVID-19 testing decisions and behaviors. This study will focus on understanding factors associated with rapid COVID-19 testing, specifically. The primary objectives of the embedded study are to 1) Determine the effectiveness of community-level intervention using door-to-door recruitment and education in increasing COVID-19 testing and 2) Compare the effectiveness of the CHW- Facilitated Self-Sampling Intervention (FSSI) vs. CHW Testing Navigation Intervention (TNI).
Medication adherence is a critical aspect of achieving optimal health outcomes. Thirty to 50% of patients adhere to long-term medication treatment of chronic diseases. Non adherence has been shown to result in worsening disease, increased healthcare expenditures, complications and even death. Medically underserved communities have higher rates of medication nonadherence and a higher prevalence of chronic conditions and often receive care at Federally Qualified Health Centers (FQHCs) which are reporting caring for increasingly complex chronic conditions. Smartphone mobile phone ownership has increased to 76% in low income Americans, but this population has been underrepresented in mobile health intervention studies. This two-group, cluster randomized by site, randomized controlled trial will investigate the effect of a medication adherence smartphone mobile application (app) which provides reminders on patient medication adherence, on medication self-efficacy, medication knowledge and medication social support. Independently, each of these concepts have been shown to support medication adherence. However in the context of delivery by a medication adherence app in a variety of chronic illnesses in a medically underserved population, little is known. It will also explore if those who accessed educational materials within the app report greater medication knowledge than those who do not and if participants who choose to use the additional Medfriend feature report greater medication social support than those who do not. The study will also explore patients' perceptions on the usefulness and satisfaction with the app features.
This Patient Forward study intends to conduct research to investigate potential genetic factors causing cancer and eczema/atopic dermatitis. The study utilizes a patient-centered design and is led by a collaborative team including The Manton Center for Orphan Disease Research, Inspire, Citizen Genetics and Pfizer. The Manton Center for Orphan Disease Research, a research program at Boston Children's Hospital that focuses on determining the genetic causes of rare and undiagnosed disorders, will work collaboratively with Inspire (inspire.com), a patient-focused research platform and social network with millions of users, to identify and recruit patients and family members for this genetic research study. Participants for this study will be asked to provide health information through surveys, questionnaires and/or interviews, and to provide a genetic sample through a blood draw or saliva sample. The study intends to combine this information to learn more about the genetic drivers in cancer and eczema/atopic dermatitis.
The "Evaluating the iNfluence of Diabetes STIGma on Medication Adherence: The ENDSTIGMA Study" was designed to develop a comprehensive diabetes stigma survey measure. The draft measure will be piloted with approximately 50 patients visiting the Vanderbilt University Medical Center (VUMC) Diabetes Clinic. This pilot data will be used to validate the new survey measure and to determine if any questions in the diabetes stigma measure are predictive of diabetes medication adherence.
The purpose of this research study is to investigate how social standing in a game of Monopoly may influence behavior.
This project will investigate the influence of experimentally manipulated perceived social standing on eating behavior and obesity risk.
The aim of this study is to determine whether blood levels of lithium or sertraline are affected by different phases of the menstrual cycle and whether there is an effect on psychiatric symptoms. Subjects are seen for two visits: one visit during the luteal phase and one visit during the follicular phase of the menstrual cycle. On each visit, they will fill out a depression, anxiety and mania rating scale. Also at each visit a 20mL blood sample will be drawn to measure progesterone level and either a lithium or sertraline level, depending on which medication the patient takes. The primary hypothesis in this study is that blood levels of lithium and sertraline will be significantly lower in women during the luteal phase of the menstrual cycle than during the follicular phase. Examination will also be made of whether symptoms will increase in severity during the luteal phase as compared to the follicular phase. The investigators expect a negative linear association between symptom severity and blood level, i.e. expect symptom severity to worsen as blood levels of lithium or sertraline decrease.
The purpose of this study is to evaluate the influence of dietary restraint, social desirability, and food type on the accuracy of dietary intake reported during a 24-hour recall.
This program is a non-diet approach to obesity prevention for older adolescents which does not promote following a special diet to manage weight; it promotes healthy behavior associated with obesity prevention. This approach is important with youth and older adolescent populations to avoid impairment in emotional well-being associated with body dissatisfaction. Healthy weight status will be achieved by improving dietary intake patterns, increasing physical activity, and improving stress management. Fall of year 01 was devoted to the recruitment of student partners (intense intervention group) and the development of partnerships. In the spring of year 01, recruited students were enrolled in two newly developed undergraduate courses across four intervention state partners, became collegiate 4-H members, planned a social marketing campaign, and/or learned to be peer mentors or student researchers. In year 02, first year college students were recruited, peer mentors were matched with a group of first year students, and the developed social marketing campaign was pilot tested on four college campuses (diffuse intervention) by the collegiate 4-H teams. In year 02, a toolkit with 24 weeks of intervention activities was also refined. In year 03, the collegiate 4-H team (intense intervention group) used the refined toolkit to test and implement the intervention on college campuses. In year 03, the assessment process for high school 4-H students (intense intervention group) will be pilot tested and college students will work with the high school students on adapting the toolkit for use in the implementation of the social marketing campaign in high school settings in year 04 (diffuse intervention). ). In year 04, the pilot and feasibility tested college intervention was tested with a randomized control trial design with 30 intervention and 29 control university partners. The adapted high school toolkit was pilot and feasibility tested in three intervention and two control high school settings. In year 05, the high school intervention was tested with a randomized control trial design with 9 intervention and 7 control high schools in one district's high schools. On all measures it is anticipated that participants in the intensive intervention group will have greater improvements than those in the diffuse intervention group and both intensive and diffuse intervention groups will have improvements over those in the control groups.
