There is minimal evidence for current interventions promoting the transition to adult healthcare for youth with type 1 diabetes (T1D). Few interventions exclusively target modifiable individual and family-based factors that contribute to transition readiness. The purpose of this paper is to describe the development of Behavioral Family Systems Therapy for Diabetes Transition (BFST-DT), a virtual family-based transition readiness intervention for adolescents with T1D.

Food insecurity is a mechanism through which the mental health impacts of systemic social inequities multiply across the lifespan. Federally administered food assistance programs improve food security, but their impact on mental health is less clear. We conducted a systematic review of all studies that reported an association between food assistance participation and mental health (N = 34), and a multilevel meta-analysis among studies that met inclusion criteria and reported sufficient statistical results (n = 21; k = 44).

Pundits have speculated that the spread of conspiracies and misinformation (termed "misbeliefs") is leading to a resurgence of right-wing, reactionary movements. However, the current empirical picture regarding the relationship between misbeliefs and collective action is mixed. We help clarify these associations by using two waves of data collected during the COVID-19 Pandemic (in Australia, N = 519, and the United States, N = 510) and democratic elections (in New Zealand N = 603, and the United States N = 609) to examine the effects of misbeliefs on support for reactionary movements (e.

Carotenoid pigments provide some of the most common exclusively biogenic markers on Earth, and these organic pigments may be present in extraterrestrial life. Raman spectroscopy can be used to identify carotenoids quickly and accurately through the inelastic scattering of laser light. In this study, we show that Raman spectra of organic matter found in hot spring bacterial assemblages exhibit "spectral overprinting" of the carotenoid spectrum by the carbon spectrum as the organic matter progressively breaks down.

Food insecurity occurs when a household lacks consistent access to food and is more prevalent in ethnic and racial minority populations. While there has been a proliferation of research linking food insecurity to obesity, these findings are mixed. It may be helpful to consider some additional geographic factors that may be associated with both factors including socioeconomic status and grocery store density.

Building local food systems through a food sovereignty lens, harnessing the right of people to control their own food systems, may enhance healthy food access and increase the consumption of fruits and vegetables in local communities. While research to date has described the outcomes of various multilevel, multicomponent food systems interventions, no known literature reviews to date have systematically examined food system interventions and dietary and health outcomes through the context of a food sovereignty lens. Utilization of a food sovereignty framework allows for the incorporation of key food systems and community-based concepts in the food environment literature.

Australian adolescents living in regional communities are significantly more likely to perform worse at school, relative to those in metropolitan communities. These disparities are partially due to the development of lower educational expectations among regional adolescents. In the current study, we tested whether the differences in educational expectations across communities were reduced when adolescents engage in extracurricular activities, and any subsequent downstream effects on academic outcomes.

Background: The school food environment is a critically important area to target the health of millions of students, especially those experiencing food insecurity. However, both students and caregivers have noted significant barriers to participation in the school meal program, including taste, lunchroom experience, and limited availability of fresh, healthy foods. There is a lack of qualitative research which considers both caregiver and adolescent perspectives, particularly among youth of color.

Refugees can experience elevated levels of psychological distress upon resettlement, although disparate outcomes over time are expected. The current study modeled trajectories of changes in distress over a 5-year period among resettled refugees and sought to explicate post-settlement factors that influence distress over time. A large-scale sample of refugees resettled in Australia (2,399) was tracked over a 5-year period, completing measures of psychological distress at each wave and initial risk and protective factors immediately after resettlement.

Using the frameworks of Latino Critical Race Theory (LatCrit) and an integrative model of developmental competencies, this study examined the roles of cultural mistrust toward education and natural mentoring relationship quality in the academic outcomes of Latinx adolescents. Participants were 294 Latinx students (52.9% female; mean age 15 years in 9th grade; 21% first-generation, 63% second-generation, and 6% third-generation immigrants) who completed surveys in 9th and 10th grades.

This study aimed to test a longitudinal model of trust in adults and psychological well-being among Latinx adolescents, a population that has received little attention in the trust literature. The participants were urban, low-income Latinx (N = 294) students at two urban, Midwestern high schools who indicated they had at least one natural mentor in 9th grade. Participants completed surveys at two-time points, in 9th and 10th grade, and responded to measures of their feelings toward adults, quality of their natural mentoring relationships, self-esteem, intrinsic academic motivation, and coping self-efficacy.

Parents/caregivers are consistently described as integral targets given their influential role in supporting and managing behaviors such as diet and physical activity. Identifying effective obesity prevention interventions to enhance and sustain parent participation is needed. Digital obesity prevention interventions are a promising strategy to improve parent/caregiver participation.

Four studies investigated the link between cross-race friendships and attraction. In Study 1, White Australian participants ( = 240) who reported friendships with racial outgroup members were more likely to report attraction to the members of the racial group their friends belonged to. Studies 2a ( = 300 White American participants) and 2b ( = 303 White British participants) showed that experiences of cross-race non-verbal intimacy, perceived cross-race reciprocity in attraction, positive perceived ingroup norms about dating cross-racially, and warmth toward the racial outgroup were particularly important in explaining the friendship-attraction link in majority samples.

Increasing substance use and decreasing well-being are typical in adolescence, yet how social contexts shape disparate development during this time is less well-understood. A latent growth class analysis was conducted that identified groups of early (N = 706; Age  = 12.20) and middle (N = 666; Age  = 14.

Introduction: Youth with refugee backgrounds experience social and socioeconomic difficulties that arise following resettlement. Research has found that sport participation generally provides youth with a protective milieu that is especially beneficial for the most disadvantaged youth. Accordingly, the current study examines whether sport participation is related to positive psychosocial outcomes for resettled adolescent refugees, and if these effects are greater for those living in socioeconomically disadvantaged communities.

Laboratory-based aversive conditioning studies have reliably induced fear toward an image of an outgroup member by pairing the image with a fear-inducing, aversive stimulus. However, laboratory-based studies have been criticized for being simplistic in comparison to the complexities of the real world. The current study is the first to apply an aversive conditioning framework to explain the formation of intergroup fear and subsequent anxiety toward, and avoidance of, the outgroup outside the laboratory.

Rationale: Humanitarian crises and ongoing conflicts around the world have created large populations of refugees who require permanent resettlement. The often-difficult pathway to resettlement for refugees places them at elevated risks for ongoing psychological and financial problems, creating an imperative to investigate the longterm outcomes for refugees as they resettle.

Objective: The current study explores how adversities before and after resettlement impact the psychological distress and experiences of financial hardship over the course of four years postsettlement for a large group of resettled refugees in Australia.

Social networking sites (SNSs) are social platforms that facilitate communication. For adolescents, peers play a crucial role in constructing the self online through displays of group norms on SNSs. The current study investigated the role of online social identity (OSI) in the relationship between adolescent exposure to alcohol-related content posted by peers on SNSs and alcohol use.
