Selected Project Experience

National Mental Health Survey (NMHS) Field Test (2015 to date)—Director, Instrumentation and Methodology. Sponsored by the Substance Abuse and Mental Health Services Administration (SAMHSA) and the National Institute of Mental Health (NIMH), the NMHS aims to (a) estimate the prevalence of mental disorders among adolescents and adults across the United States, (b) investigate correlates of mental health problems and patterns of care, and (c) provide a platform for follow-up studies on priority subgroups of interest. The NMHS is a nationally representative sample of 13,500 respondents age 13 and older interviewed over a 12-month period. Adult, adolescent, and parent questionnaires covering an extensive set of mental disorder assessments, dimensional symptom scales, measures of personality features and mental health service use, as well as risk and protective factor assessments will be used. As Director for Instrumentation and Methodology, lead a team responsible for developing the screening instrument as well as adapting existing mental health instruments for ACASI administration with adult and adolescent respondents and telephone and web administration for parent respondents.

National Inmate Survey (2005 to date)—Principal Investigator. Sponsored by the Bureau of Justice Statistics (BJS), this congressionally mandated study involves an annual survey of incarcerated adults to determine the prevalence and nature of sexual victimization in U.S. correctional facilities. Year 1 entailed interviews with approximately 71,000 prison and jail inmates in 428 correctional facilities. In Year 2, approximately 80,000 inmates were interviewed across 501 correctional facilities. In Year 3 RTI surveyed more than 100,000 inmates in approximately 650 randomly selected correctional facilities, including federal prisons, state prisons, local jails, and other facilities, such as those operated by Immigration and Customs Enforcement, tribal authorities, and the military. Activities include developing a touch-screen audio computer-assisted self-interviewing (ACASI) instrument, sampling facilities and inmates within

facilities, communicating with each facility to schedule data collection, collecting data, conducting data processing and data analysis, and reporting results. Manages all aspects of project to ensure the study is completed on schedule and within budget and that the methodology developed will collect these highly sensitive data in a manner that protects the rights and privacy of the respondents, minimizes respondent burden, and maximizes data quality and unit and item response rates. Also serves as task leader for instrumentation.

Survey of Prison Inmates (SPI) (2011 to 2014)—Principal Investigator. Sponsored by the Bureau of Justice Statistics (BJS), this survey will be the first full-scale implementation of the methodology developed as part of the redesign project described below. The data collection effort will focus exclusively on inmates housed in state and federal prisons and will be called the Survey of Prison Inmates. Activities include developing a computer-assisted personal interviewing (CAPI) instrument, sampling facilities and inmates within facilities, communicating with each facility to schedule data collection, collecting data, conducting data processing and data analysis, and reporting results. Manages all aspects of projects to ensure the study is completed on schedule and within budget, and the survey minimizes burden to participating facilities and inmates, while maximizing data quality.

Demographic Surveys ACASI Response Bias Research for Collecting Sensitive Information (2011 to 2012)—Project Director. Sponsored by the Census Bureau, this project developed an approach for evaluating the benefits and drawbacks of including ACASI as part of a survey protocol. Activities included conducting a thorough review of the ACASI research conducted to date; identifying data sets suitable for model testing and evaluation; and developing statistical models to evaluate the use of ACASI with regard to impact on (1) error in the survey estimates, (2) cost, and (3) nonresponse.

Redesign of the Survey of Inmates in Prisons and Local Jails (2009 to 2013)—Principal Investigator. Sponsored by BJS, this survey involved the redesign of the methodology and questionnaire used to collect data on inmates housed in the United States. RTI reviewed the existing methodology, including sample design, instrument content, mode of administration, logistics of interviewing in prisons and jails, weighting approaches, and cost drivers, and developed a revised approach for conducting the survey in collaboration with BJS. RTI pretested the questionnaire and sampling methods during a pilot test and provided a report and recommendations to BJS in advance of full-scale implementation of the methodology. Managed all aspects of the project to ensure that the study is completed on schedule and on budget and that the methodology developed will meet the analytic needs of BJS without creating undue burden on participating facilities and inmates.
