Identity Distress Among Youth Exposed to Natural Disasters: Associations with Level of Exposure,Posttraumatic Stress,and Internalizing Problems

Identity distress involves intense or prolonged upset or worry about personal identity issues including long-term goals, career choice, friendships, sexual orientation and behavior, religion, values and beliefs, and group loyalties. Research suggests that trauma exposure and subsequent posttraumatic stress disorder (PTSD) symptoms may negatively affect identity development and psychological adjustment. However, little is known about their specific associations with identity distress and internalizing problems among disaster-exposed adolescents. This study aimed to examine these associations in a sample of 325 adolescents (60% female; 89% African American) who experienced a major natural disaster and its aftermath. The results indicated that identity distress was positively associated with age, hurricane exposure, PTSD symptoms, and internalizing problems. Linear regression analyses also showed that identity distress was uniquely associated with internalizing symptoms and that there was an indirect effect of hurricane exposure on identity distress via PTSD symptoms. PTSD symptoms moderated the link between identity distress and internalizing symptoms, with a significant positive slope found for youth with more PTSD symptoms. Findings were generally consistent with previous work and predictions, and they add to the extant knowledge about identity distress by providing data on the linkages among disaster exposure, posttraumatic stress, and internalizing problems in adolescents.     

Practical Aspects of Recruitment and Retention in Clinical Trials of Rare Genetic Diseases: The Phenylketonuria (PKU) Experience

Bringing treatments for rare genetic diseases to patients requires clinical research. Despite increasing activism from patient support and advocacy groups to increase access to clinical research studies, connecting rare disease patients with the clinical research opportunities that may help them has proven challenging. Chief among these challenges are the low incidence of these diseases resulting in a very small pool of known patients with a particular disease, difficulty of diagnosing rare genetic diseases, logistical issues such as long distances to the nearest treatment center, and substantial disease burden leading to loss of independence. Using clinical studies of phenylketonuria as an example, this paper discusses how, based on the authors’ collective experience, partnership among clinicians, patients, study coordinators, genetic counselors, dietitians, industry, patient support groups, and families can help overcome the challenges of recruiting and retaining patients in rare disease clinical trials. We discuss specific methods of collaboration, communication, and education as part of a long-term effort to build a community committed to advancing the medical care of patients with rare genetic diseases. By talking to patients and families regularly about research initiatives and taking steps to make study participation as easy as possible, rare disease clinic staff can help ensure adequate study enrollment and successful study completion.     

The Impact of Legislative Standards on Batterer Intervention Program Practices and Characteristics

Changes in social policy are often pursued with the goal of reducing a social problem by improving prevention efforts, intervention program practices, or participant outcomes. State legislative standards for intimate partner violence intervention programs have been adopted nearly universally across the US, however, we do not know whether such standards actually achieve the intended goal of affecting programs’ policies and practices. To assess the effect that batterer intervention program (BIP) standards have on policies and practices of programs, this study used longitudinal surveys collected as part of an ongoing evaluation conducted from 2001 to the present to compare intervention program (N = 74) characteristics and practices at three time points before and after the adoption of standards in Oregon. Analyses were conducted to examine all BIPs in Oregon at each time point, as well as change among a subset of programs in existence at all survey assessments. Results indicate that across all programs, the use of mixed gender group co-facilitation increased by 14 % between 2004 and 2008, while program length increased by approximately 12 weeks. However, other practices such as programs’ coordination with community partners were unchanged. Analyses of within-program change revealed fewer differences, with only program length increasing significantly over the three assessments. These and other findings indicate that while standards affected program length as intended, other practices commonly addressed by legislative standards remained unchanged. The findings provide needed information regarding programs’ compliance with components of the standards, the potential need for compliance monitoring, and the potential impact of state standards on program effectiveness and on the prevalence of intimate partner violence.     

How School can Teach Civic Engagement Besides Civic Education: The Role of Democratic School Climate

Civic engagement, defined as involvement in community life, is influenced by reciprocal relationships between individuals and contexts and is a key factor that contributes to positive youth development. The present study evaluates a theoretical model linking perceived democratic school climate with adolescent civic engagement (operationalized as civic responsibility and intentions for future participation), taking into account the mediating role of civic discussions and perceived fairness at school. Participants were 403 adolescents (47.9 % male) ranging in age from 11 to 15 years old (mean age = 13.6). Path analysis results partially validated the proposed theoretical model. Higher levels of democratic school climate were associated with higher levels of adolescent civic responsibility; the association was fully mediated by civic discussions and perceived fairness at school. Adolescents’ civic responsibility, then, was positively associated with a stronger intention to participate in the civic domain in the future.     

Adolescent Dating Violence: Application of a U.S. Primary Prevention Program in St. Lucia

The purpose of this study was to examine the Choose Respect dating violence prevention program (Centers for Disease Control and Prevention, 2006b , n.d.‐a) with secondary students in St. Lucia. Multivariate analysis of variance results indicated that the Choose Respect program had a positive influence on participants’ attitudes about control in relationships. Significant gender and school effects were found. Implications of these findings for primary prevention efforts targeting dating violence in St. Lucia and limitations of the study are discussed.     

Behavioral pharmacology of the odor span task: Effects of flunitrazepam,ketamine, methamphetamine and methylphenidate

The Odor Span Task is an incrementing non‐matching‐to‐sample procedure that permits the study of behavior under the control of multiple stimuli. Rats are exposed to a series of odor stimuli and selection of new stimuli is reinforced. Successful performance thus requires remembering which stimuli have previously been presented during a given session. This procedure has been frequently used in neurobiological studies as a rodent model of working memory; however, only a few studies have examined the effects of drugs on performance in this task. The present experiments explored the behavioral pharmacology of a modified version of the Odor Span Task by determining the effects of stimulant drugs methylphenidate and methamphetamine, NMDA antagonist ketamine, and positive GABA_A modulator flunitrazepam. All four drugs produced dose‐dependent impairment of performances on the Odor Span Task, but for methylphenidate and methamphetamine, these occurred only at doses that had similar effects on performance of a simple odor discrimination. Generally, these disruptions were based on omission of responding at the effective doses. The effects of ketamine and flunitrazepam were more selective in some rats. That is, some rats tested under flunitrazepam and ketamine showed decreases in accuracy on the Odor Span Task at doses that did not affect simple discrimination performance. These selective effects indicate disruption of within‐session stimulus control. Overall, these findings support the potential of the Odor Span Task as a baseline for the behavioral pharmacological analysis of remembering.
