This is a competing continuation, now in its 18th year of finding, of the primary R01 that has supported the Prevention Science and Methodology Group (Designs and Analyses for Mental Health Preventive Trials MH40859).  These aims extend the current work by developing an integrated set of new statistical models, Multilevel Growth Mixture Models, that incorporate person-level, time, and context in the same methodology.  We also present new statistical designs for randomized field trials and incorporate nonlinear “additive” models.  A second aim focuses on designs and analyses for low baserate disorders, including suicide, psychosis, and drug abuse/dependence.  The third aim will focus on the designs and analyses specifically appropriate for implementing interventions with communities.  We will develop new designs for implementation trials, including trials outside a trial and trials after a trial.

                                                                                                                                                               This proposal, directed by Sheppard Kellam, extends the follow-up of two cohorts of 2311 Baltimore children, now in late adolescence, who comprised the study sample for a randomized field trial of two classroom interventions in first and second grade. These interventions focused on improving learning and improving classroom behavior, particularly lessening aggression, two risk factors for later depressive symptoms and conduct disorder. This particular study would model developmental course in relevant social fields throughout most of childhood and adolescence, as well as examine the consequences of successfully improving or failing to improve early in life the consequences of successfully improving or failing to improve early in life.

Co-PI, C. Hendricks Brown                        5%      2002 – 2007

USF 64031020

              

                Funded by the National Institute on Drug Abuse, this is involves a third generation preventive field trial of a classroom-based intervention aimed at early risk factors for substance abuse.  Both first-grade children and their teachers are randomized to intervention or standard classrooms in first grade.  The intervention aims at enhancing reading, through improved curriculum, training, and coaching, at aggressive/disruptive behavior through the Good Behavior Game and other classroom management techniques, and through a parent-teacher partnership.  There are three phases to this study, an effectiveness trial for the first cohort, which is followed through third grade, a sustainability trial examining impact in second and third cohorts, and a scalability trial examining how impact is affected when the intervention is expanded to whole schools.

P30MH068685 ASU Prevention Research Center for Families in Stress

USF # 64031025

Co-Investigator, C Hendricks Brown

                  

                   The Center focuses on preventive interventions for children who are at risk for developing mental health problems because of exposure to high stress situations; parental divorce, parental death and inner city, Mexican American children in transition to high school. These stressors are known to increase risk for development of serious mental health problems such as depression and conduct problems as well as substance abuse and social adaptation problems. The application builds on an 18-year history of productive research with these populations which has demonstrated efficacy to reduce mental health problems, diagnosis of mental disorder, substance use and improve academic achievement. The overall objective of the application is to make the transition from University based studies of the efficacy of preventive interventions to the effectiveness of programs as implemented in community agencies. The Center proposes four Cores to accomplish this overall goal. The Principal Research Core utilizes an interdisciplinary approach to prepare the interventions for delivery in community agencies. Concepts and methods from service marketing, quality management and educational design are used to redesign the programs so that they can be readily implemented in community agencies. Experts on cross-cultural adaptation collaborate to make interventions that are robust to be delivered to a wide range of ethnic and cultural groups. The multidisciplinary teams work with key stakeholders to learn how to adapt the programs through the family courts and agencies that work with bereaved children. The Research Methods Core develops collaborative workgroups of methodologists and substantive researchers to focus on five methodological issues: measurement, variability in outcomes, implementation and compliance with interventions, multilevel data, and economic analysis. The Research Network Development Core develops collaborations with Family Courts, provider agencies and Bereavement Agencies to implement evidence-based prevention programs in natural service delivery settings. The Operations Core provides critical infrastructure for Center decision making and management, data collection in remote sites, data management, statistical analysis, analysis of ethical issues and training.

1R56MH078580 Antidepressant Treatment and Suicidality: Biostatistical/Methodological Solutions

NIMH PI Robert Gibbons                                        August 2006 – August 2008

C Hendricks Brown, Co-PI  8%

 

The purpose of this proposal is to develop, test, and apply new statistical design and analytical methodologies that can be used to identify low base rate drug - adverse event (AE) interactions. These new methods will then be applied to a wide range of existing non-experimental datasets to examine the relationship between SSRIs and suicide ideation, attempts, and completion. We have designed this research project as an integral collaboration between biostatisticians, research psychiatrists and clinicians, economists, and pharmacoepidemiologists, working with large ecological and electronic patient databases covering years where antidepressant use is varying dramatically. The first set of aims will lead to the development of new biostatistical methods for making inferences from spontaneous reporting and electronic medical record databases. Specifically, we will 1. develop new statistical designs and analyses for identifying drug-AE interactions using both spontaneous (SRS) and active reporting systems (ARS); 2. develop biostatistical methods to address selection and reporting bias in electronic medical record databases; 3. develop statistical methods for large-scale drug-AE screening. The second set of aims involves the critical application of these methods to existing large scale databases in order to examine the role of antidepressants in suicidality among different populations. The datasets range from the spontaneous reporting system (MedWatch), to electronic medical record databases (e.g., VA, PHARMetrics, Kaiser, and PHARMO, Indian Health Service), to the synthesis of information from randomized clinical trials (RCTs). The work in this proposal will be carried out by a research consortium that will study national and international drug safety issues.

An Integrated Suicide Prevention Program for Underserved and Rural Communities

 

                                                                        3/2007 – 12/2008

 

This project addresses the need for refining and field testing a suicide prevention program for youth from underserved or rural areas.  The purpose of this work is to prepare a flexible intervention for underserved and rural communities that is suitable for use in different communities and can then be tested with a rigorous evaluation design. Specifically for this project, we will merge the most recent findings of the Georgia Gatekeeper randomized trial involving QPR, now being completed in Cobb County, Georgia, with the Sources of Strength program, designed by Mark LoMurray from the state of North Dakota.  This project’s critical step of refining and field testing an intervention is required before scaling up such an intervention in preparation for a large evaluation study.  Building on our rigorous testing of QPR, we will be developing a two-stage training for school staff to increase effective gatekeeper behavior among those adults who are most likely to communicate with distressed youth.  Adding the Sources of Strength program allows us to directly target the help-seeking behavior of distressed youth and also to respond to youth referred for suicidality in communities where services are unavailable or severely limited.  The successful linkage of these programs would build on the strong data collection and research base now available for QPR in Cobb County and the promising initial results of Sources of Strength in underserved, rural, and tribal communities.
