Exposure to Community Violence and the Trajectory of Internalizing and Externalizing Symptoms in a Sample of Low-Income Urban Youth.

This study examined trajectories of psychopathology in a sample of low-income urban youth and tested exposure to community violence as a predictor of these trajectories. Self-report and parent-report survey measures of psychological problems and exposure to community violence were collected annually over 3 years from a sample of 364 fifth- to ninth-grade low-income urban youth (64% female; 95% youth of color). Linear growth models showed that youth experienced declines in both internalizing and externalizing symptoms across adolescence. Exposure to community violence was more strongly associated with externalizing symptoms than with internalizing symptoms but predicted declines in both types of symptoms. Results also indicated that youth reported more internalizing and externalizing symptoms than their parents reported for them. Exposure to community violence may explain unique trajectories of mental health problems among low-income urban youth. In addition, youth efforts to adopt a tough façade in the face of community violence could lead to higher rates of externalizing problems relative to internalizing problems, whereas desensitization processes may better explain reductions in both types of symptoms over time. Finally, youth report may be more valid than parent report in the context of urban poverty.

Seeking systemic change: risk and protective factors affecting low-income urban youth.

This themed issue presents five articles tackling the topic of risk and protective processes affecting children and adolescents living in urban poverty. Through their research, the authors seek understanding of the particular challenges that low-income urban youth face, with the ultimate goal of understanding how best to intervene at various levels of the ecological system. Within this broad theme, studies examine specific stressors, mediators, and moderators that impact the mental health of youth living in urban poverty. The final article presents a data-driven, community-based intervention for this population.

Development of cities mentor project: an intervention to improve academic outcomes for low-income urban youth through instruction in effective coping supported by mentoring relationships and protective settings.

This manuscript summarizes an iterative process used to develop a new intervention for low-income urban youth at risk for negative academic outcomes (e.g., disengagement, failure, drop-out). A series of seven steps, building incrementally one upon the other, are described: 1) identify targets of the intervention; 2) develop logic model; 3) identify effective elements of targets; 4) vet intervention with stakeholders; 5) develop models for sustaining the intervention; 6) develop measures of relevant constructs currently missing from the literature; 7) assess feasibility and usability of the intervention. Methods used to accomplish these steps include basic research studies, literature reviews, meta-analyses, focus groups, community advisory meetings, consultations with scholarly consultants, and piloting. The resulting intervention provides early adolescents in low-income urban communities with a) training in contextually relevant coping, b) connection to mentors who support youth's developing coping strategies, and c) connection to youth-serving community organizations, where youth receive additional support.

Posttraumatic growth among children and adolescents: a systematic review.

Stress and trauma research has traditionally focused on negative sequelae of adversity. Recently, research has begun to focus on positive outcomes, specifically posttraumatic growth (PTG) - "positive change experienced as a result of the struggle with trauma" - which emphasizes the transformative potential of one's experiences with highly stressful events and circumstances. The positive changes of PTG are generally thought to occur in five domains: new possibilities, relating to others, personal strength, appreciation of life, and spiritual change. The study of PTG has, for the most part, been centered on adults, and not until very recently has there been sufficient research on PTG among children and adolescents to justify a review. The current systematic review of the literature on PTG among children and adolescents included 25 studies that tested associations between PTG and conceptually-relevant variables found to be associated with PTG in adults and hypothesized to play similar roles in young people, including environmental characteristics, distress responses, social processes, psychological processes, positive outcomes, and demographic variables. Links were made between a theoretical model of PTG among youth and findings of the current review. Limitations and recommendations for future research are discussed.

Smaller superior temporal gyrus volume specificity in schizotypal personality disorder.

BACKGROUND: Superior temporal gyrus (STG/BA22) volume is reduced in schizophrenia and to a milder degree in schizotypal personality disorder (SPD), representing a less severe disorder in the schizophrenia spectrum. SPD and Borderline personality disorder (BPD) are severe personality disorders characterized by social and cognitive dysfunction. However, while SPD is characterized by social withdrawal/anhedonia, BPD is marked by hyper-reactivity to interpersonal stimuli and hyper-emotionality. This is the first morphometric study to directly compare SPD and BPD patients in temporal lobe volume. METHODS: We compared three age-, sex-, and education-matched groups: 27 unmedicated SPD individuals with no BPD traits, 52 unmedicated BPD individuals with no SPD traits, and 45 healthy controls. We examined gray matter volume of frontal and temporal lobe Brodmann areas (BAs), and dorsal/ventral amygdala from 3-T magnetic resonance imaging. RESULTS: In the STG, an auditory association area reported to be dysfunctional in SPD and BPD, the SPD patients had significantly smaller volume than healthy controls and BPD patients. No group differences were found between BPD patients and controls. Smaller BA22 volume was associated with greater symptom severity in SPD patients. Reduced STG volume may be an important endophenotype for schizophrenia-spectrum disorders. SPD is distinct from BPD in terms of STG volume abnormalities which may reflect different underlying pathophysiological mechanisms and could help discriminate between them.
