The Impact of Role Models, Mentors, and Heroes on Academic and Social Outcomes in Adolescents.

Background Identity formation is a dynamic process and key developmental task that begins in adolescence. During this time, children look to adults as role models and mentors. These adults can have a significant impact on adolescents' decisions of appropriate or inappropriate behaviors, potentially causing a positive or negative change. Little research has been performed to identify these role models and understand how they affect the development of physical and mental health of children.  Objective The goal of this study is to see if there is a relationship between identified role models, mentors, and/or heroes and adolescents' interest in education, participation in risky behavior, confidence level, happiness, safety, violence-related behaviors, and physical activity.  Methods In this study, 198 children aged 11-18 years were identified on the scheduling platforms at various Hershey Medical Center sites to take a 10-minute survey via RedCap. The survey identified their role model, mentor, and/or hero and followed up with outcome questions from validated tools. Results The results show that 140 participants (70.7%) identified having a role model compared to 88 (44.4%) having mentors and 61 (30.8%) having heroes, and family members were the most identified figures for each category. There were significant differences between identified categories of role models, mentors, and heroes, and interest in education, happiness, risky behavior, and safety, while no significant differences were found for violence-related behavior, physical activity, and confidence level. Adolescents with family heroes had safer behavior (2.39 ± 0.70) than those with celebrity heroes (3.16 ±1.86, p=0.0277), and those with peer heroes (11.3 ± 2.31) had more risky behavior than those with celebrity heroes (9.16 ± 1.98, p=0.0347). However, children with adult peer heroes had a higher interest in education (2.00 ± 0) compared to those with celebrities (3.79 ± 1.03, p=0.0246) or public figures (3.78 ± 1.09, p=0.0333) as their heroes. Additionally, those with family (3.48 ± 1.05) or adult peers (3.32 ± 1.38) as their mentors had a higher interest in education compared to those with same-age peer mentors (5.80 ± 1.30, p=<0.0001). Adolescents with family mentors also had higher happiness scores (3.25 ± 0.33) than those with same-age peer mentors (2.59 ± 1.47, p=0.0358) and also engaged in safer behavior (2.52 ± 0.80) compared to all other categories (3.03 ±1.59, 0.0462).  Conclusion These results point to the idea that who adolescents choose to look up to has effects on various aspects of their life that could affect both their physical and mental health status, with family members having the most impact. Further research could explore differences between which family members are chosen as role models, mentors, and heroes and what effect they might have on adolescent development.

Personality Traits and Social Supports in Adolescents With Persistent Postconcussion Symptoms.

OBJECTIVES: To determine whether adolescents with persistent postconcussion symptoms (PPCS) differ from healthy peers in their personality traits and social supports. SETTING: Specialty Concussion Clinic and Primary Care Clinic affiliated with an academic medical center. PARTICIPANTS: Ninety-seven adolescents (42 with PPCS, 55 healthy peers; age: 15 ± 2 years). DESIGN: Participants completed a web-based survey that included medical and demographic characteristics, mechanisms of concussion, 10-item Big Five Inventory, and Child and Adolescent Social Support Scale. A Student's 2-tailed t test with multiple testing corrections was used to compare the youths with PPCS to healthy peers. MAIN MEASURES: The primary outcome was PPCS, defined by the presence of 2 or more concussion-related symptoms on the Post-Concussion Symptom Scale (PCSS), lasting for more than 4 weeks after initial injury. The secondary outcome was perceived personality traits and social support, based on the 10-item Big Five Inventory and the Child and Adolescent Social Support Scale, respectively. RESULTS: The PPCS group had higher neuroticism scores on their Big Five Inventory than healthy peers. They also reported less social support from teachers and classmates than healthy peers. CONCLUSION: Youths with PPCS report specific personality and social support characteristics that differ from their peers. These findings suggest that individual personality and school-based social supports may influence concussion recovery.

A Review of MicroRNA Biomarkers in Traumatic Brain Injury.

There is growing public concern surrounding traumatic brain injury (TBI). TBI can cause significant morbidity, and the long-term sequelae are poorly understood. TBI diagnosis and management rely on patient-reported symptoms and subjective clinical assessment. There are no biologic tools to detect mild TBI or to track brain recovery. Emerging evidence suggests that microRNAs (miRNAs) may provide information about the injured brain. These tiny epigenetic molecules are expressed throughout the body. However, they are particularly important in neurons, can cross the blood-brain barrier, and are securely transported from cell to cell, where they regulate gene expression. miRNA levels may identify patients with TBI and predict symptom duration. This review synthesizes miRNA findings from 14 human studies. We distill more than 291 miRNAs to 17 biomarker candidates that overlap across multiple studies and multiple biofluids. The goal of this review is to establish a collective understanding of miRNA biology in TBI and identify clinical priorities for future investigations of this promising biomarker.
