Exercise, Cognition, And Cannabis Use In Adolescents, Ileana Pacheco-Colón
Exercise, Cognition, And Cannabis Use In Adolescents, Ileana Pacheco-Colón
FIU Electronic Theses and Dissertations
Heavy and/or chronic cannabis use has been associated with neurocognitive impairment and decline, often in domains such as memory and executive functioning. On the other hand, exercise has been linked to positive effects on brain and cognitive health across the lifespan, as well as to better substance use outcomes. Despite this, little is known about the ways in which exercise could help prevent or ameliorate adverse cannabis-related outcomes among adolescents.
Through three separate studies, the current dissertation examines interrelations among exercise, cognition, and cannabis use in children and adolescents in an effort to determine whether exercise can prevent or ameliorate …
The Development Of Reward Processing And Risky Behaviors In The Brain, Michelle L. Ramos
The Development Of Reward Processing And Risky Behaviors In The Brain, Michelle L. Ramos
FIU Electronic Theses and Dissertations
Adolescence is a period of heightened risk taking which can lead to many negative consequences. This increased risk taking may be related to developmental changes in the reward processing system in the brain. The current study proposes to investigate individual differences in the development of the reward processing system as well as cognitive-based regulatory processes in the developing brain, and how heterogeneity in neural and autonomic activity related to these processes may predict risk-taking behavior. Despite crucial developmental changes in the reward system leading to hypersensitivity to reward, there is great variability in risk-taking and sensation seeking behaviors seen in …
Considering Culture And Context: A Mixed-Methods Approach To Examining Adolescent Engagement And Parent Satisfaction In Urban Out-Of-School-Time Programs, Jacqueline Oluwakemi Moses
Considering Culture And Context: A Mixed-Methods Approach To Examining Adolescent Engagement And Parent Satisfaction In Urban Out-Of-School-Time Programs, Jacqueline Oluwakemi Moses
FIU Electronic Theses and Dissertations
Adolescents of color living in poverty are at elevated risk for mental health problems with limited access to quality care, and 21% of youth in poverty are diagnosed with mental health disorders that, left untreated, lead to significant long-term consequences. Positive future orientation – optimistic expectations for graduation, gainful employment, and healthy relationships – among vulnerable adolescents has been identified as a unique protective factor associated with positive mental health trajectories. Out-of-school-time (OST) programs in neighborhood settings can promote positive future orientation and maximize benefits for adolescents, but we know little about cultural and contextual influences on youth enrollment and …
Sexual Health Promotion Programming For Youth In Or At-Risk For Foster Care: Improving Knowledge, Attitudes, And Behaviors., Maya Boustani
Sexual Health Promotion Programming For Youth In Or At-Risk For Foster Care: Improving Knowledge, Attitudes, And Behaviors., Maya Boustani
FIU Electronic Theses and Dissertations
Among girls in foster care, 48% become pregnant at least once by age 19 (Dworkey & Courtney, 2010). Teen moms are less likely to graduate from high school and their children also are more likely to be placed in foster care due to abuse or neglect (Hoffman, 2006). Furthermore, 50% of 21-year-old men aging out of foster care report they have gotten someone pregnant, compared to 19% of their peers not involved in foster care (Courtney et al., 2007). Youth in or at-risk for foster care (YFC) report limited knowledge about, access to, and use of condoms; ambivalent attitudes toward …
The Development Of A Depression Preventive Intervention For Adolescents With Attention-Deficit/Hyperactivity Disorder, Michael C. Meinzer
The Development Of A Depression Preventive Intervention For Adolescents With Attention-Deficit/Hyperactivity Disorder, Michael C. Meinzer
FIU Electronic Theses and Dissertations
Despite the considerable progress made identifying attention-deficit/hyperactivity disorder (ADHD) as a risk for depressive outcomes in adolescence and adulthood as well as potential explanations for the co-occurrence of ADHD and unipolar depression (i.e., emotion regulation, family support, and reward responsivity), targeted depression prevention efforts have not yet been implemented for adolescents with ADHD. Thus, the specific aims were as follows: (1) develop a behaviorally oriented, tailored, depression preventive intervention for adolescents with ADHD targeting variables empirically supported to account for the covariation between ADHD and depression (Behaviorally Enhancing Adolescents’ Mood; BEAM), (2) pilot BEAM in a small sample of adolescents …
Open Trial And Pilot Randomized Controlled Trial Of A Novel Program To Reduce Perceived Burdensomeness, Ryan M. Hill
Open Trial And Pilot Randomized Controlled Trial Of A Novel Program To Reduce Perceived Burdensomeness, Ryan M. Hill
FIU Electronic Theses and Dissertations
To date, suicide prevention programs for adolescents have not demonstrated sustained reductions in suicide-related behaviors and further program development is called for, particularly for the prevention of non-clinical suicide risk. This research utilizes the Interpersonal-Psychological Theory of Suicide in the development of the LEAP Program, a novel, web-based suicide prevention program targeting reductions in cognitions of perceived burdensomeness. An open trial of the program was conducted to examine the feasibility of the study protocol, generate feedback regarding the LEAP program modules, and refine the program modules. A pilot randomized controlled trial of the program was also conducted to examine participant …
