BACKGROUND: Schizophrenia is a disorder of brain connectivity and altered neurodevelopmental processes. Cross-sectional case-control studies in different age groups have suggested that deficits in cortical thickness in childhood-onset schizophrenia may normalize over time, suggesting a disorder-related difference in cortical growth trajectories. METHODS: We acquired magnetic resonance imaging scans repeated over several years for each subject, in a sample of 106 patients with childhood-onset schizophrenia and 102 age-matched healthy volunteers. Using semiparametric regression, we modeled the effect of schizophrenia on the growth curve of cortical thickness in ~80,000 locations across the cortex, in the age range 8 to 30 years. In addition, we derived normative developmental modules composed of cortical regions with similar maturational trajectories for cortical thickness in typical brain development. RESULTS: We found abnormal nonlinear growth processes in prefrontal and temporal areas that have previously been implicated in schizophrenia, distinguishing for the first time between cortical areas with age-constant deficits in cortical thickness and areas whose maturational trajectories are altered in schizophrenia. In addition, we showed that when the brain is divided into five normative developmental modules, the areas with abnormal cortical growth overlap significantly only with the cingulo-fronto-temporal module. CONCLUSIONS: These findings suggest that abnormal cortical development in schizophrenia may be modularized or constrained by the normal community structure of developmental modules of the human brain connectome.

Resting state functional magnetic imaging (fMRI) is a novel means to examine functional brain networks. It allows investigators to identify functional networks defined by distinct, spontaneous signal fluctuations. Resting state functional connectivity (RSFC) studies examining child and adolescent psychiatric disorders are being published with increasing frequency, despite concerns about the impact of motion on findings. Here we review important RSFC findings on typical brain development and recent publications of child and adolescent psychiatric disorders. We close with a summary of the major findings and current strengths and limitations of RSFC studies.

OBJECTIVE Policy makers have increasingly turned to learning collaboratives (LCs) as a strategy for improving usual care through the dissemination of evidence-based practices. The purpose of this review was to characterize the state of the evidence for use of LCs in mental health care. METHODS A systematic search of major academic databases for peer-reviewed articles on LCs in mental health care generated 421 unique articles across a range of disciplines; 28 mental health articles were selected for full-text review, and 20 articles representing 16 distinct studies met criteria for final inclusion. Articles were coded to identify the LC components reported, the focus of the research, and key findings. RESULTS Most of the articles included assessments of provider- or patient-level variables at baseline and post-LC. Only one study included a comparison condition. LC targets ranged widely, from use of a depression screening tool to implementation of evidence-based treatments. Fourteen crosscutting LC components (for example, in-person learning sessions, phone meetings, data reporting, leadership involvement, and training in quality improvement methods) were identified. The LCs reviewed reported including, on average, seven components, most commonly in-person learning sessions, plan-do-study-act cycles, multidisciplinary quality improvement teams, and data collection for quality improvement. CONCLUSIONS LCs are being used widely in mental health care, although there is minimal evidence of their effectiveness and unclear reporting in regard to specific components. Rigorous observational and controlled research studies on the impact of LCs on targeted provider- and patient-level outcomes are greatly needed.

This exploratory study examines changes in suicidal ideation among a sample (N = 28) of homeless youth, ages 11-14, residing within family shelters in a large metropolitan area. Changes in suicidal ideation from pretest to posttest are compared across two group approaches to delivering HIV prevention. Youth and their families participating in the HOPE Family Program, incorporating a family strengthening approach, are compared to those receiving a traditional health education-only approach. Multivariate analyses reveal that youth in the HOPE Family Program were 13 times more likely to report a decrease of suicidal ideation. These findings indicate that health education programs integrating a family strengthening approach hold promise for positively impacting mental health outcomes for vulnerable youth.

Between 1950 and 1969, on a serendipitous basis, psychiatric drug development flourished. However, there has been a steep decline in the development of new medication classes. Instead of new molecular entities, slight molecular modifications producing "me-too" drugs attempted to garner market share. With failing profitability, industry is now withdrawing from psychiatric medication development. Managed care drastically shortened contact between patients and clinicians, so the possible observation of unexpected benefits has been nullified. The randomized, parallel-groups design met FDA requirements for specific pharmacological efficacy. However, it does not determine whether a patient who improved while drug-treated required the drug or would have gotten better on his own. Further, pathophysiology benefit remains obscure. The major psychotropic drugs have no benefits for normal subjects. Their remarkable benefits must stem from a necessary interaction with a pathophysiological state. Therefore, understanding therapeutic benefit by treating normal subjects becomes unlikely. The claim that therapeutic knowledge in psychiatry proceeds from bench to bedside has proven vacuous, primarily because of our limited understanding of brain pathophysiology. The utility of the alternative intensive design for understanding diagnosis, therapeutic benefit, and pathophysiology is emphasized.

The VUKA family program is one of the only evidence-based interventions to promote positive psychosocial outcomes in South African HIV-infected pre- and early adolescents and their families. In this paper, we discuss the collaborative process by which a multidisciplinary team of clinicians, researchers, counselors, and artists/educators and families adapted and developed VUKA for this population using community-based participatory research methods. We describe the intervention and explore lessons learned that may be applicable across contexts related to international collaboration and adapting evidence-based interventions so that they are likely to be acceptable, feasible, and effective in a given setting and country context.

The aim of this study was to investigate the temporal abilities of children treated by surgery for a malignant tumor in the cerebellum, both in the perception and the production of rhythm. Children with a diagnosed medulloblastoma and age-matched control children were tested in a rhythm discrimination task and a sensorimotor synchronization task. Their motor and cognitive capabilities were also assessed through a battery of age-adapted neuropsychological tests. The results did not show any significant difference in performance between groups for the discrimination task. On the contrary, children with cerebellar lesions produced longer and more variable inter-tap intervals (ITI) in their spontaneous motor tempo (SMT) than did the control children. However, the length and, to a lesser extent, the variability of their SMT decreased after a synchronization phase, when they had been instructed to tap in synchrony with a beep. During the synchronization task, the children with medulloblastoma succeeded to modify the length of their ITI in response to an auditory rhythm, although with better success when the inter-stimuli intervals (ISI) were shorter than when they were longer than the ITIs of their own SMT. Correlational analyses revealed that children's poorer synchronization performance was related to lower scores in neuropsychological tests assessing motor dexterity and processing speed.

The goal of this study was to examine the impact of supplementing Trauma-focused Cognitive Behavioral Therapy (TF-CBT; Cohen et al., 2006) with evidence-based engagement strategies on foster parent and foster youth engagement in treatment, given challenges engaging foster parents in treatment. A randomized controlled trial of TF-CBT standard delivery compared to TF-CBT plus evidence-based engagement strategies was conducted with 47 children and adolescents in foster care and one of their foster parents. Attendance, engagement, and clinical outcomes were assessed 1 month into treatment, end of treatment, and 3 months post-treatment. Youth and foster parents who received TF-CBT plus evidence-based engagement strategies were more likely to be retained in treatment through four sessions and were less likely to drop out of treatment prematurely. The engagement strategies did not appear to have an effect on the number of canceled or no-show sessions or on treatment satisfaction. Clinical outcomes did not differ by study condition, but exploratory analyses suggest that youth had significant improvements with treatment. Strategies that specifically target engagement may hold promise for increasing access to evidence-based treatments and for increasing likelihood of treatment completion.
