Substance abuse treatment and the recurrence of maltreatment among caregivers with children living at home: a propensity score analysis.

Policy and programmatic initiatives of the last decade have focused on increased coordination of services and expansion of prompt substance abuse treatment for mothers initially involved with child welfare services (CWS). Yet, little evidence has been amassed concerning the implications of this approach on the recurrent need for CWS. Data are from a large national probability sample of children and their caregivers involved with CWS following an allegation of maltreatment. Data include the recurrence of maltreatment reports for this group of children who remain at home. Selected from 1,101 caregivers with an indicated substance abuse problem, a group of 224 clients who did not receive services were compared with 224 treated clients. Event history analyses showed that clients who received substance abuse treatment were nearly twice as likely to have another child abuse report within 18 months. Reasons why participation in substance abuse treatment may result in greater involvement with CWS are posited.

Forecasting length of stay in child residential treatment.

A sample of 126 consecutively admitted residential treatment children (mean age = 9.86, SD=1.84; 70.6% male; 42.1% African American; 50% Caucasian) were studied over a five-year period to identify predictors of length-of-stay. Cox regression was the primary statistical method used to analyze psychiatric and behavioral rating data for children assessed by teachers and treatment staff using the Devereux Scales of Mental Disorders (DSMD). Parental alcohol abuse, and children's age, medication status, race, initial DSMD total and critical pathology scores, were predictive of length-of-stay. Residential length-of-stay was strongly linked to initial levels of psychiatric symptomatology. Models that can help forecast length of stay are vital tools in helping to improve both clinical and utilization management strategies.

Social information-processing skills training to promote social competence and prevent aggressive behavior in the third grades.

This article describes a school-based study designed to promote social competence and reduce aggressive behavior by strengthening children's skills in processing social information and regulating emotions. Three successive cohorts of 3rd graders (N = 548) from 2 schools participated. In 2000-2001, children received a routine health curriculum; in 2001-2002, students received the Making Choices: Social Problem Solving Skills for Children (MC) program; and in 2002-2003, children received MC supplemented with teacher and parent activities. Compared with children in the routine condition, children in both MC conditions were rated lower on posttest social and overt aggression and higher on social competence. Moreover, they scored significantly higher on an information-processing skills posttest. The findings suggest that prevention programs can strengthen social- emotional skills and produce changes in aggressive behavior.

Initial behavior outcomes for the peacebuilders universal school-based violence prevention program.

PeaceBuilders is a universal, elementary-school-based violence prevention program that attempts to alter the climate of a school by teaching students and staff simple rules and activities aimed at improving child social competence and reducing aggressive behavior. Eight matched schools (N > 4,000 students in Grades K-5) were randomly assigned to either immediate postbaseline intervention (PBI) or to a delayed intervention 1 year later (PBD). Hierarchical linear modeling was used to analyze results from assessments in the fall and spring of 2 consecutive school years. In Year 1, significant gains in teacher-rated social competence for students in Grades K-2, in childself-reported peace-building behavior in Grades K-5, and reductions in aggressive behavior in Grades 3-5 were found for PBI but not PBD schools. Differential effects in Year 1 were also observed for aggression and prosocial behavior. Most effects were maintained in Year 2 for PBI schools, including increases in child prosocial behavior in Grades K-2. Implications for early universal school-based prevention and challenges related toevaluating large-scale prevention trials are discussed.

Behavioral change trajectories of partial hospitalization children.

Forecasting treatment outcomes is essential to improving service delivery. Hierarchical linear modeling was used to construct behavioral change trajectories and help predict treatment responsiveness for 97 partial hospitalization children. Overall, children evidenced statistically significant improvement in psychiatric symptomatology. Younger age, female gender, number of previous out-of-home placements, and lower IQ scores were associated with increased psychopathology and poorer treatment response. Properly configured day treatment can provide an effective organizing platform for implementing complex treatment regimes.

Specific side effects of long-term imipramine management of panic disorder.

In a recent study, the authors suggested that tachycardia, dry mouth, and sweating continued to burden patients with panic disorder with agoraphobia who have shown marked and stable response to 6 months of imipramine treatment at the fixed, weight-adjusted dose of 2.25 mg/kg/day. Although sexual dysfunction and weight gain were not a significant burden in that study, they are important problems in long-term treatment with antidepressant drugs. In the present study, in the context of a randomized, double-blind, placebo-controlled, 1-year discontinuation and maintenance study of 53 patients with panic disorder with agoraphobia who respond to imipramine, the authors examine the extent and the specificity of these five side effects of imipramine maintenance using data at pretreatment, at the end of 24 weeks of open imipramine treatment (or month 0 of randomization), and at months 2, 4, 6, 8, 10, and 12 of randomized treatment. Hierarchical linear modeling and repeated measures of analyses of variance in subsamples of completers confirmed that dry mouth, sweating, and increased heart rate constitute a significant and specific enduring burden of imipramine maintenance treatment. The data also revealed that weight gain is a significant and specific side effect of 1-year imipramine maintenance treatment; however, the likelihood of reporting sexual dysfunction decreased over time, with no difference between the placebo and imipramine maintenance conditions. The results are discussed in the context of previous studies of imipramine side effects in the management of depression and the available literature of sexual and weight side effects of antidepressant medications in the treatment of anxiety disorders.

Predictors of entering a long-term drug treatment study of panic disorder.

Three hundred thirty-three consecutive individuals with panic and agoraphobic-like symptoms were evaluated as part of the screening for entry in a long-term imipramine treatment study of panic disorder with agoraphobia. The present report compares three subgroups of potential subjects--those who entered the study (n = 139, 41.7%), those who were rejected from participation based on exclusion criteria (n = 161, 48.3%), and those who qualified to enter but refused participation (n = 33, 10.0%)-in order to characterize pretreatment attrition and address two specific questions: What variables other than inclusion and exclusion criteria predict the likelihood of entering the trial?, and What variables significantly predict the likelihood of refusal to participate? Logistic regression analysis revealed that the likelihood of entering the trial was influenced significantly and independently by a number of variables that included extroversion, anxiety, and work satisfaction and performance measures. The refused and rejected groups differed significantly on a number of variables that were not a priori exclusionary criteria, such as a history of substance abuse other than alcohol and current use of alcohol to decrease anxiety, but none of these variables emerged as independent, significant predictors of refusing behavior as a separate category of nonparticipation. Findings suggest the presence of factors common to both the rejected and the refused groups that significantly influence pretreatment attrition and caution that categorizing pretreatment attrition into refused and rejected categories may not always be clear cut. Research and clinical implications are briefly discussed.

Characteristics and trajectories of treatment foster care youth.

Using cross-sectional analyses in conjunction with dynamic modeling (hierarchical linear modeling), the authors profiled 119 treatment foster care youth and constructed behavioral change trajectories for a subset of 97 children. Children generally showed improvements in internalizing and critical pathology problem domains but remained the same on measures of externalizing behaviors and total problem score. The number of previous out-of-home placements was positively associated with increased levels of psychiatric symptomatology and served as the most robust predictor for modeling treatment response trajectories across problem domains. Placement instability places the well-being of children at heightened risk, therefore, accurate assessment of child need and risk in relation to caregiver capacities is critical.
