One hundred thirty seven adolescents (M=15.3 yrs, SD=1.0 yr, n=72 girls) were recruited into temperament groups when they were 4 months of age based on reactivity to novel auditory/visual stimuli (Fox, Henderson, Rubin, Calkins, & Schmidt, 2001). Behavioral inhibition was observed across infancy (14 and 24 months). Additionally, self-reported substance-related problems and behavioral risk-taking was assessed during adolescence. High behavioral inhibition increased risk for substance-related problems among boys, whereas high behavioral inhibition protected against substance-related problems among girls, B=-1.18, SE=.48, 95% CI=-2.13 to -.24; p<.05. Additionally, high behavioral inhibition protected lower risk-taking children from adolescent substance-related problems whereas high behavioral inhibition increased risk for substance-related problems among higher risk-taking children, B=.04, SE=.02, 95% CI=.00 to .08. Findings from this prospective, multi-informant, longitudinal study suggest that risk-taking and gender may interact with temperamental traits to place adolescents at differential risk for substance-related related behavior problems.

Although literature supports the association between harmonious coparenting practices and lowered child problems, little is known about coparenting influences among family constellations in the foster care system. Via a compilation of a new coparenting practices measure, we examined similarities and differences on foster parent-derived perceptions of support/flexibility, shared communication, conflict/triangulation, and total coparenting between foster and biological parents and their independent contribution to child internalizing and externalizing problems. Self-reports were gathered from foster parents (N=80) in 2 groups: kin and nonkin. As compared with nonkin, kin foster parents reported higher perceived support/flexibility, shared communication, and total coparenting. A tendency for higher conflict/triangulation among kin foster parents was also found. After considering foster parent group, psychological distress, and harsh discipline, hierarchical regression analyses revealed that perceived total coparenting and conflict/triangulation contributed to child internalizing and externalizing problems. Results support the linkage between perceptions of coparenting and child problems among caregivers (foster and biological alike) in kin and nonkin arrangements and highlight training in coparenting in general, and conflict management in particular, as an important intervention focus to reduce the high level of child problems in this vulnerable population.

An implementation study of cognitive-behavioral therapies (CBT) was conducted for traumatized youth in a postdisaster context. Headed by the New York State Office of Mental Health, the study targeted youth (N = 306) ages 5-21 affected by the World Trade Center disaster. They received either trauma-specific CBT or brief CBT skills depending upon the severity of trauma symptoms. Clinicians were trained to deliver these interventions and received monthly consultation. A regression discontinuity design was used to assess optimal strategies for matching need to service intensity. At 6-months postbaseline, both groups had improved. Rate of change was similar despite differences in severity of need. The implications for the implementation of evidence-based treatments postdisaster are discussed

OBJECTIVE: The aim of the Longitudinal Assessment of Manic Symptoms (LAMS) study is to examine differences in psychiatric symptomatology, diagnoses, demographics, functioning, and psychotropic medication exposure in children with elevated symptoms of mania (ESM) compared to youth without ESM. This article describes the initial demographic information, diagnostic and symptom prevalence, and medication exposure for the LAMS cohort that will be followed longitudinally. METHOD: Guardians of consecutively ascertained new outpatients 6 to 12 years of age presenting for treatment at one of 10 university-affiliated mental health centers were asked to complete the Parent General Behavior Inventory-10-Item Mania Scale (PGBI-10M). Patients with scores >/= 12 on the PGBI-10M (ESM+) and a matched sample of patients who screened negative (ESM-) were invited to participate. Patients were enrolled from December 13, 2005, to December 18, 2008. RESULTS: 707 children (621 ESM+, 86 ESM-; mean [SD] age = 9.4 [2.0] years) were evaluated. The ESM+ group, compared to the ESM- group, more frequently met DSM-IV criteria for a mood disorder (P < .001), bipolar spectrum disorders (BPSD; P < .001), and disruptive behavior disorders (P < .01). Furthermore, they showed poorer overall functioning and more severe manic, depressive, attention-deficit/hyperactivity, disruptive behavioral, and anxiety symptoms. Nevertheless, rates of BPSD were relatively low in the ESM+ group (25%), with almost half of these BPSD patients (12.1% of ESM+ patients) meeting DSM-IV criteria for bipolar disorder not otherwise specified. ESM+ children with BPSD had significantly more of the following: current prescriptions for antipsychotics, mood stabilizers, and anticonvulsants (P < .001 for each); psychiatric hospitalizations (P < .001); and biological parents with elevated mood (P = .001 for mothers, P < .013 for fathers). ESM+ children with BPSD were also lower functioning compared to ESM+ children without BPSD. CONCLUSIONS: Although ESM+ was associated with higher rates of BPSD than ESM-, 75% of ESM+ children did not meet criteria for BPSD. Results suggest that longitudinal assessment is needed to examine which factors are associated with diagnostic evolution to BPSD in children with elevated symptoms of mania.

The current study showed that visual fixation of obstacles is not required for rapid and adaptive navigation of obstacles. Children and adults wore a wireless, head-mounted eye-tracker during a visual search task in a room cluttered with obstacles. They spontaneously walked, jumped, and ran through the room, stepping up, down, and over obstacles. Both children and adults navigated adaptively without fixating obstacles, however, adults fixated less often than children. We discuss several possibilities for why obstacle navigation may shift from foveal to peripheral control over development.

We investigated the effect of action performance on perceptual judgments by evaluating accuracy in judging whether doorways allowed passage. Participants made judgments either before or after walking through doorways of varying widths. Participants in the action-first group benefited from action feedback and made more accurate judgments compared to a perception-first group that judged doorways before walking through them. Action feedback aided perceptual judgments by facilitating scaling to body dimensions: Judgments in the action-first group were strongly related to height, weight, and torso size, whereas judgments in the perception-first group were not.

Analytic tools for addressing spontaneous brain activity, as acquired with fMRI during the 'resting-state,' have grown dramatically over the past decade. Along with each new technique, novel hypotheses about the functional organization of the brain are also available to researchers. We review six prominent categories of resting-state fMRI data analysis: seed-based functional connectivity, independent component analysis, clustering, pattern classification, graph theory, and two 'local' methods. In surveying these methods, we address their underlying assumptions, methodologies, and novel applications

OBJECTIVE: Little is known about the neural underpinnings of generalized social phobia, which is defined by a persistent heightened fear of social disapproval. Using event-related functional MRI (fMRI), the authors examined whether the intent of an event, which mediates the neural response to social disapproval in healthy individuals, differentially affects response in generalized social phobia. METHOD: Sixteen patients with generalized social phobia and 16 healthy comparison subjects group-matched on age, gender, and IQ underwent fMRI scans while reading stories that involved neutral social events, unintentional social transgressions (e.g., choking on food at a party and coughing it up), or intentional social transgressions (e.g., disliking food at a party and spitting it out). RESULTS: Significant group-by-transgression interactions were observed in ventral regions of the medial prefrontal cortex. Healthy individuals tended to show increased blood-oxygen-level-dependent responses to intentional relative to unintentional transgressions. Patients with generalized social phobia, however, showed significantly increased responses to the unintentional transgressions. They also rated the unintentional transgressions as significantly more embarrassing than did the comparison subjects. Results also revealed significant group main effects in the amygdala and insula bilaterally, reflecting elevated generalized social phobia responses in these regions to all event types. CONCLUSIONS: These results further implicate the medial prefrontal cortex in the pathophysiology of generalized social phobia, specifically through its involvement in distorted self-referential processing. These results also further underscore the extended role of the amygdala and insula in the processing of social stimuli more generally in generalized social phobia.
