Psychological outcomes of bariatric surgery in morbidly obese adolescents
Vazzana, Andrea D
The adverse impact obesity can have on a person's medical and mental health is overwhelming. As the prevalence and severity of childhood obesity and its related comorbidities continue to swell, there are inadequate effective, long-term solutions for the nonsurgical management of morbidly obese youth. Although they are still controversial, refined surgical procedures have improved the safety and efficacy of bariatric surgery. It is being increasingly used with morbidly obese adolescents under the care of a multidisciplinary treatment team. Bariatric surgery typically results in marked weight loss and the resolution or reduction of comorbid conditions. At a more normalized weight, these adolescents often experience substantial life changes in areas that have the potential to positively, and sometimes negatively alter a person's quality of life. It is important to understand these complex changes in order to facilitate the adolescent's positive long-term outcome. Despite their importance, there are limited empirical studies pertaining to adolescent psychosocial outcomes. Current results support the benefits of bariatric surgery in this population, but more rigorous research studies with prospective data collection and long-term follow up are necessary before pediatric bariatric surgery can be officially sanctioned for this special needs population.
Outcome expectations and outcome values of proactive, reactive and nonaggressive boys [Dissertation]

Two types of classes of social cognitions that influence children's decisions about their own aggressive behavior were examined among third- and fourth-grade male students. Specifically, outcome expectations and outcome values were assessed with children subtyped as proactively aggressive, reactively aggressive, pervasively aggressive, or nonaggressive. Group differences were examined along the broad classification of aggressive or nonaggressive status. The influence of situational provocation on expectations and values was also examined.
