The benefit of participating in Out-of-School Time (OST) arts programs has been widely documented in studies that often reflect impact over short timeframes. Youth arts organisations often bear extraordinary claims about the impact of programs, and the value they hold especially in the lives of those who face difficult social circumstances. This…

Gender dysphoria (GD) and Autism Spectrum Disorder (ASD) co-occur relatively often, but there is no evidence-based treatment for this specific group. Therefore, we examined the effects of a group intervention for adolescents with ASD and GD in a pilot study with a pre-post-test design. The adolescents completed questionnaires on quality of life,…

Background: Youth-focused co-design, involving active collaboration between researchers, designers, clinicians and end users, is essential for enhancing the acceptability, feasibility and effectiveness of digital mental health interventions (DMHIs). However, most literature on co-design comes from high-income countries and offers limited…

This study explored how mentoring begins and the benefits provided for African American sexual and/or gender minority (SGM) youth. Participants were mentors and mentees living in three Mid-Atlantic cities. Mentees (ages 15-21, n = 14) identified as African American; cisgender male, transgender female, or non-binary assigned male; and had sexual…

It is well established that positive youth development (PYD) programs improve adolescent psycho-social wellbeing; however, it remains unclear if PYD programs developed for able-bodied adolescents can be implemented with adolescents with disabilities in low-resource settings. We conducted a pragmatic trial of an evidence-based PYD program…

Connections between prosociality and antisocial behaviors have been recognized; however, little research has studied their developmental links longitudinally. This is important to illuminate during early adolescence as a sensitive period for social development in which prosociality could protect against the development of later antisocial…

Engagement in preventive health behaviors (PHBs; i.e., healthy eating, sleep, and physical activity) during adolescence is associated with reduced risks for chronic conditions, such as diabetes, in adulthood. Although several interventions seek to improve adolescents' engagement in health promoting behaviors, racial- and income-based disparities…

We explored assent procedures to promote assent and treatment effectiveness for an autistic adult. The objective, at the request of the participant, was to evaluate an innovative approach to (a) identify aversive auditory stimuli and (b) teach Steven, a 19-year-old male, appropriate responses in the presence of these stimuli without directly…

This evaluation study addressed the need to increase the participation of teenagers in the Youth Service Agency ABC (YSA ABC). ABC offers positive, powerful, and empowering experiences for area teens. These programs help them with character development, financial literacy, emotional intelligence, healthy well-being, and many other skills and tools…

According to the "Diagnostic and Statistical Manual of Mental Disorders" (DSM-5; American Psychiatric Association, 2013), an substance use disorder (SUD) involves patterns of symptoms caused by using a substance that an individual continues taking despite its negative effects. Though there are 11 specific DSM-5 criteria for an SUD, they…

According to relational frame theory (RFT), temporal relational responding is key to important repertoires, including sequencing, ordering, planning, and time understanding. Previous studies have taught several other varieties of relational responding (e.g., comparison, deictics) but relatively little work has been done in the case of temporal…

Background: ADHD is a generally persistent neurodevelopmental condition that can have significant consequences if left untreated, and medication, often in conjunction with psychotherapy, is the first-line treatment with well-established efficacy. Adolescents and young adults (AYAs) represent a particularly vulnerable and understudied subgroup and…

Previous research indicates that learners appear to connect with nature and have heightened environmental perceptions after participating in environmental education programs (EEPs). Positive changes in attitudes toward nature are important because they can precede environmentally responsible behaviors, such as individuals' leadership on…

Background: Online exercise programming reduces transportation and scheduling barriers. This study explored the feasibility of online resistance training for individuals with Down syndrome. Method: Thirteen individuals (3 M/10 F, age: 21.7 ± 5.9 years) began a 10-week programme delivered using a website with pre-recorded exercise videos (45--60…

Purpose: Adolescents and adults with Down syndrome are noted to display symptoms and behaviors consistent with a diagnosis of Obsessive Compulsive Disorder. While evidenced-based interventions, including psychopharmacology and therapeutic interventions including exposure and response prevention, exist and effectively treat obsessive-compulsive…
