Predictors and moderators in the randomized trial of multifamily psychoeducational psychotherapy for childhood mood disorders.

This study investigated predictors and moderators of mood symptoms in the randomized controlled trial (RCT) of Multi-Family Psychoeducational Psychotherapy (MF-PEP) for childhood mood disorders. Based on predictors and moderators in RCTs of psychosocial interventions for adolescent mood disorders, we hypothesized that children's greater functional impairment would predict worse outcome, whereas children's stress/trauma history and parental expressed emotion and psychopathology would moderate outcome. Exploratory analyses examined other demographic, functioning, and diagnostic variables. Logistic regression and linear mixed effects modeling were used in this secondary analysis of the MF-PEP RCT of 165 children, ages 8 to 12, with mood disorders, a majority of whom were male (73%) and White, non-Hispanic (90%). Treatment nonresponse was significantly associated with higher baseline levels of global functioning (i.e., less impairment; Cohen's d = 0.51) and lower levels of stress/trauma history (d = 0.56) in children and Cluster B personality disorder symptoms in parents (d = 0.49). Regarding moderators, children with moderately impaired functioning who received MF-PEP had significantly decreased mood symptoms (t = 2.10, d = 0.33) compared with waitlist control. MF-PEP had the strongest effect on severely impaired children (t = 3.03, d = 0.47). Comprehensive assessment of demographic, youth, parent, and familial variables should precede intervention. Treatment of mood disorders in high-functioning youth without stress/trauma histories and with parents with elevated Cluster B symptoms may require extra therapeutic effort, whereas severely impaired children may benefit most from MF-PEP.

What differentiates children visiting outpatient mental health services with bipolar spectrum disorder from children with other psychiatric diagnoses?

OBJECTIVES: To determine the contribution of parent-reported manic symptoms, family history, stressful life events, and family environment in predicting diagnosis of bipolar spectrum disorders (BPSD) in youth presenting to an outpatient psychiatric clinic. METHODS: A total of 707 6- to 12-year-old children [621 with elevated symptoms of mania (ESM+) based on screening via the Parent General Behavior Inventory 10-item Mania Scale (PGBI-10M) and 86 without ESM (ESM-)] received a comprehensive assessment. RESULTS: Of the 629 with complete data, 24% (n = 148) had BPSD. Compared to those without BPSD (n = 481), children with BPSD: were older (Cohen's d = 0.44) and more likely to be female (Cohen's d = 0.26); had higher parent-endorsed manic symptom scores at screening (Cohen's d = 0.36) and baseline (Cohen's d = 0.76), more biological parents with a history of manic symptoms (Cohen's d = 0.48), and greater parenting stress (Cohen's d = 0.19). Discriminating variables, in order, were: baseline PGBI-10M scores, biological parent history of mania, parenting stress, and screening PGBI-10M scores. Absence of all these factors reduced risk of BPSD from 24% to 2%. CONCLUSIONS: History of parental manic symptoms remains a robust predictor of BPSD in youth seeking outpatient care, even after accounting for parent report of manic symptoms in the child at screening. However, the risk factors identified as associated with BPSD, together had limited value in accurately identifying individual participants with BPSD, highlighting the need for careful clinical assessment.

Clinical characteristics of children receiving antipsychotic medication.

This study explored the demographic and diagnostic features of children who were currently receiving antipsychotics compared to children who were receiving other psychotropics in a cohort of children with and without elevated symptoms of mania (ESM). Participants were recruited from 10 child outpatient mental health clinics associated with four universities. Guardians with children between 6-12 years who presented for new clinical evaluations completed the Parent General Behavior Inventory-10 Item Mania Scale (PGBI-10M). All children who scored ≥12 on the PGBI-10M and a select demographically matched comparison group of patients who scored ≤11 were invited to participate. Children were divided into two groups: those receiving at least one antipsychotic medication and those receiving other psychotropic medications. The groups were compared on demographics, diagnoses, psychiatric symptoms, functioning, and past hospitalizations. Of the 707 children enrolled in the Longitudinal Assessment of Manic Symptoms (LAMS) study, 443 (63%) were prescribed psychotropic medication at baseline: 157 (35%) were receiving an antipsychotic and 286 (65%) were prescribed other agents. Multivariate results indicated that being prescribed antipsychotics was related to being white, previous hospitalization, having a psychotic or bipolar 1 disorder and the site where the child was receiving services (p<0.001). In this sample, it is relatively common for a child to be prescribed an antipsychotic medication. However, the only diagnoses associated with a greater likelihood of being treated with an antipsychotic were psychotic disorders or unmodified DSM-IV bipolar 1 disorder.

An e-Research approach to Web-scale music analysis.

The growing quantity of digital recorded music available in large-scale resources such as the Internet archive provides an important new resource for musical analysis. An e-Research approach has been adopted in order to create a very substantive web-accessible corpus of musical analyses in a common framework for use by music scholars, students and beyond, and to establish a methodology and tooling that will enable others to add to the resource in the future. The enabling infrastructure brings together scientific workflow and Semantic Web technologies with a set of algorithms and tools for extracting features from recorded music. It has been used to deliver a prototype system, described here, that demonstrates the utility of LINKED DATA for enhancing the curation of collections of music signal data for analysis and publishing results that can be simply and readily correlated to these and other sources. This paper describes the motivation, infrastructure design and the proof-of-concept case study and reflects on emerging e-Research practice as researchers embrace the scale of the Web.

Characteristics of children with elevated symptoms of mania: the Longitudinal Assessment of Manic Symptoms (LAMS) study.

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.
