Few have examined mechanisms explaining the link between perceived neighborhood unsafety, neighborhood social processes, and depressive symptoms for Black adolescents. The goal of this study was to examine the role of perceived control as a mechanism linking perceptions of neighborhood unsafety and depressive symptoms, and neighborhood cohesion as a protective factor. Participants were 412 Black adolescents living in a major Mid-Atlantic urban center in the United States (49% female, M = 15.

Background: Residence in high-crime neighborhoods, especially in childhood, is linked to mental health issues later. Detecting distinct neurobiological processes underlying the effects of this environmental stressor may be critical to identifying prevention and intervention targets. This study examined the relationships of levels of a circulating inflammatory protein with social and monetary reward-related brain function among adolescents who lived in high- versus low-crime neighborhoods during childhood.

Mechanisms linking residential mobility and depressive symptoms among urban-dwelling African American adolescents have received little attention. This study examined neighborhood cohesion as a possible mechanism. Participants were 358 urban-dwelling African American adolescents (M  = 14.

Introduction: Negative emotional reactivity and the neighborhood environment have been individually associated with marijuana use outcomes; however, less is known about whether neighborhood factors differentiate the association between negative emotional reactivity and marijuana use. The present study examined whether neighborhood risk (i.e.

Living in high crime areas and rumination each have been identified as risk factors for depression among youth, yet it is unclear how crime and rumination may synergistically increase the risk of adolescent depression. Adolescents (N = 309; 51% female, M 12.9, SD = 0.

Individuals with bipolar spectrum disorder (BSD) frequently meet criteria for comorbid anxiety disorders, and anxiety may be an important factor in the etiology and course of BSDs. The current study examined the association of lifetime anxiety disorders with prospective manic/hypomanic versus major depressive episodes. Participants were 244 young adults (aged 17-26) with milder forms of BSDs (i.

The CAD triad hypothesis (Rozin, Lowery, Imada, & Haidt, 1999) stipulates that, cross-culturally, people feel anger for violations of autonomy, contempt for violations of community, and disgust for violations of divinity. Although the disgust-divinity link has received some measure of empirical support, the results have been difficult to interpret in light of several conceptual and design flaws. Taking a revised methodological approach, including use of newly validated (Study 1), pathogen-free violations of the divinity code, we found (Study 2) little evidence of disgust-related phenomenology (nausea, gagging, loss of appetite) or action tendency (desire to move away), but much evidence of anger-linked desire to retaliate, as a major component of individuals' projected response to "pure" (pathogen-free) violations of the divinity code.

Background: This study evaluated the clinical interpretations of single photon emission computed tomography (SPECT) using a cerebral blood flow and a dopamine transporter tracer in patients with chronic mild traumatic brain injury (TBI). The goal was to determine how these two different scan might be used and compared to each other in this patient population.

Methods And Findings: Twenty-five patients with persistent symptoms after a mild TBI underwent SPECT with both (99m)Tc exametazime to measure cerebral blood flow (CBF) and (123)I ioflupane to measure dopamine transporter (DAT) binding.
