Adolescence is a period of social, physical, and neurobiological transitions that may leave individuals more vulnerable to the development of adjustment problems such as internalizing and externalizing symptomatology. Extant research demonstrates how self-regulation can predict adjustment outcomes in adolescence; however, it has yet to be examined how longitudinal growth in self-regulation may predict individual differences in symptomatology. That is, adolescents who develop self-regulatory capacities such as executive functioning (EF; including shifting, working memory, and inhibitory control) more slowly than their peers may be at increased risk for maladjustment. Data were collected from 167 adolescents and their primary caregiver over approximately three years. At each time point, adolescents completed three behavioral tasks that capture the underlying dimensions of EF, and both adolescents and their primary caregiver completed measures of adolescent symptomatology. Parallel process growth curve modeling was used to test the associations between initial levels and trajectories of both EF and adjustment. Results did not reveal any significant associations between initial levels of EF and adjustment or between growth in EF and growth in adjustment. Furthermore, there were no differential associations between the different EF dimensions. However, post-hoc analyses revealed that longitudinal increases in growth of EF predicted lower externalizing (but not internalizing) symptomatology at Time 3 (controlling for Time 1). Findings suggest that those with more rapid EF development may be better able to regulate behavioral and affective states and thus be less likely to develop externalizing symptoms, and that both early levels and growth in EF may be important predictors of adolescent outcomes. / Master of Science / Adolescence is a period of social, physical, and neurobiological transitions that may leave individuals more vulnerable to the development of symptoms such as anxiety, depression, aggression, and delinquency. Self-regulation affects these outcomes in adolescence; however, individuals demonstrate growth in self-regulation abilities at different rates. Thus, the current study sought to examine how differences in self-regulation (specifically, executive functioning (EF)) development over time may contribute to different behavioral and emotional symptoms in adolescence. Data were collected from 167 adolescents and their primary caregiver over approximately three years. At each time point, adolescents completed three behavioral tasks that capture EF, and both adolescents and their primary caregiver completed measures of adolescent symptoms. Results showed that there were no significant associations between initial levels of EF and symptoms, or between growth in EF and growth in symptoms. Furthermore, different aspects of EF (such as memory, attention, and inhibitory control) did not differentially predict symptomatology. However, additional analyses revealed that increases in growth of EF over time predicted lower symptoms of aggression and delinquency at Time 3. Findings suggest that those with more rapid EF development may be better able to regulate behavioral and emotional states and thus be less likely to develop these types of symptoms, and that both early levels and growth in EF may be important predictors of adolescent outcomes.

The primary purpose of the investigation was to examine differences in symptom-expression between Caucasians and Asians in response to college-stress. College-stress was defined as adjustment problems that students experience as a function of exposure to a college environment. The propensity of each group to express symptoms in response to stress in somatic (i.e., bodily) versus psychological (i.e., anxiety and depression) modes was investigated. Previous reports have postulated a somatization hypothesis for Asians, as opposed to a psychologization tendency in Caucasians. Intra-Asian differences with respect to symptom-expression were also examined. Data were collected electronically. 115 graduate students participated in the study. Using Fisher's transformations to compare correlations, it was found that neither the somatization nor the psychologization hypotheses were supported. However, within Asians depression demonstrated a stronger association with stress than somatic symptoms. A subsidiary purpose of this investigation was to determine whether attribution-style was an aspect of culture that could lead to differences in symptom-expression. It was hypothesized that Asians would have a more external attribution-style, while Caucasian-Americans would have a more internal style. External style was hypothesized to be related to a somatic tendency, while internal style was hypothesized to be related to a psychological tendency. None of these hypotheses were supported. Finally, some exploratory analyses were carried out to assess the effect of demographic variables on symptom-expression. Sex was related to anxiety symptoms, while level of education was related to somatic symptom-reports. Overall, these findings highlight the need for cross-cultural research in psychology to adopt a more systemic approach in studying variables, as opposed to using merely country/culture as an independent variable. / Ph.

The purpose of the current study was to further explore the relations between parent trauma, parenting behavior, child trauma, and child adjustment. The sample included 358 children (191 boys and 167 girls) and their primary caregiver (48 fathers and 310 mothers). The children's ages ranged from 10 to 17 with an average age of 13. Parent trauma was not found to be related to child trauma through parenting behaviors. Child trauma was found to mediate the relations between parenting and child adjustment. There was some evidence of parenting mediating the relation between parent trauma and child adjustment. This research underscores the importance of understanding the risk and protective factors associated with parent trauma and its influences on child trauma and adjustment as well as the importance of good parenting as a protective factor. Further, this study supports past research which highlights those pathways which lead to resilience. / Master of Science

Objectification theory (Fredrickson & Roberts, 1997) has been used to explain how mechanisms related to socialization, sexual objectification, and psychological variables interact to predict mental health difficulties. Among a sample of 626 undergraduate women (age 18-24), this study empirically tested components of Moradi and Huang’s (2008) model and extended it by including additional socialization experiences (i.e., sexual abuse, societal pressures regarding weight and body size). Structural equation modeling analyses suggested that the model provided a good fit to the data and the model was tested in the confirmatory sample. Across the two samples, high levels of Body Shame and low levels of Internal Bodily Awareness directly led and high levels of Societal Pressures Regarding Weight and Body Size, Internalization of Cultural Standards of Beauty, and Self-objectification indirectly led to increased Bulimic Symptomatology and accounted for 65 to 73% of the variance in Bulimic Symptomatology. A history of sexual abuse and sexual objectification were not consistently supported within the model and do not appear to be as salient as the experience of societal pressures regarding weight and body size in understanding women’s experience of bulimic symptomatology. Implications for practice and future research are discussed.

The incarceration of mentally ill youth is a serious problem not receiving the same attention as in adults. In this study, we examine the prevalence of psychopathology and level of behavioral symptomatology in incarcerated youth versus youth receiving community mental health services or hospitalization. We randomly recruited youth from middle South Carolina served by a local CMHC (n = 60), youth served by the state adolescent inpatient program (n = 50), and youth in the S.C. Dept. of Juvenile Justice facilities from the same region (n = 75). We used the DISC-PC 2.3 to evaluate DSM-III-R diagnoses and the CBCL and YSR to evaluate behavioral symptomatology. On the DISC, incarcerated youth had significantly higher mean number of diagnoses and symptoms than CMHC youth, but lower numbers than hospitalized youth. Level of "caseness" (at least one diagnosis) was 86% in hospital youth, 72% in incarcerated youth, and 60% in CMHC youth. The groups differed in CBCL mean total T, internalizing T, and externalizing T scores as well as mean YSR internalizing T scores. Our results indicate the comparability in level of psychopathology in incarcerated and community-treated populations of youth, and the need to develop diversionary programs to prevent the entry of such youth into the juvenile justice system.

Previous research has shown peer victimization during adolescence to have strong lasting effects on mental health. Religiousness and forgiveness are two factors that are positively related to mental health and the current study proposes that they may have a protective influence against the negative effects of peer victimization. Additionally, religiousness and forgiveness may be related in that forgiveness may be a link in the religiousness/health relationship. The purpose of the current study was to examine the relationships among religiousness, forgiveness and mental health in the context of peer victimization during adolescence. Mental health was measured by internalizing symptomatology and emotion regulation. Analyses were conducted using Structural Equation Modeling. Results indicate that forgiveness may indeed be a link in the religiousness/health relationship but only when examining private religious practices. Results further show that religiousness may not be a strong protective factor in the context of peer victimization and that certain dimensions of forgiveness (specifically benevolence motivations) may actually exacerbate the effects of peer victimization on internalizing symptomatology rather than act as a protective factor. / Master of Science

The purpose of this study was to explore whether overweight college dieters, engaged in self-structured weight loss efforts, experienced physical symptomatology that has previously been associated with severe caloric restriction. The relationships between physical symptomatology, self-efficacy, and future dieting behavior were also investigated. Forty college students (21 female, Mage = 19.58 years, SD= 1.85) self-reported caloric intake and completed self-efficacy measures and physical symptom reports for three weeks. Results indicated that weekly physical symptom reports were not associated with caloric deficit and did not predict future dieting behavior. Physical symptoms were negatively related to self-efficacy for dieting and exercise as predicted, but in several analyses, higher self-efficacy actually predicted less calorie restriction. Physical symptom reports were predicted by trait neuroticism and neuroticism was also significantly and negatively associated with eating and exercise self-efficacy. Results raised issues about the accuracy of caloric restriction reporting and suggested that personality characteristics may have an important impact on an individual's perception of dieting experiences and levels of self-efficacy during dieting. / Master of Science

Previous studies have reported that deficits in attention are often a common complaint in individuals suffering from pain and attentional impairment in patients with pain has been demonstrated on a variety of neuropsychological measures. Much of the research to-date, however, has not taken into account extraneous factors that may contribute to observed cognitive deficits. Using the California Verbal Learning Test - II, attention and memory performance was examined in two clinical populations (pain and mild traumatic brain injury) while controlling for effort using the Word Memory Test. Controlling for effort led to different explanations of poor performance on attention variables. While mild deficits were expected, and could be accounted for by psychological factors (i.e. somatization), extremely poor performance was more likely related to poor effort. The findings of this study strongly support the necessity of measuring effort during neuropsychological and pain psychological evaluations.
