RAND researchers have pioneered several different methodologies, such as the Delphi method and robust decisionmaking, and continue to apply their methodological expertise in multidisciplinary projects that may require a range of capabilities, including modeling and simulation, survey research, economic or statistical analysis, or planning and forecasting.
This study analyzes the performance of poverty prediction models based on small area estimation (SAE) techniques.
The objective of the present study is to describe the extension of the National Institutes of Health Patient-Reported Outcomes Measurement Information System (PROMIS®) pediatric parent proxy-report item banks for parents of children ages 5–7 years, and to investigate differential item functioning (DIF) between the data obtained from parents of 5–7-year-old children with the data obtained from parents of 8–17 year-old children in the original construction of the scales.
In response to mounting evidence about skyrocketing morbidity, mortality, and costs associated with healthcare–associated infections (HAIs), in 2009, the US Department of Health and Human Services (HHS) issued the HHS HAI Action Plan to enhance collaboration and coordination and to strengthen the impact of national efforts to address HAIs.
An important challenge in comparative effectiveness research is the lack of infrastructure to support pragmatic clinical trials, which compare interventions in usual practice settings and subjects.
This study uses behavioral experiments and structured decision-maker interviews to evaluate the results of scenario discovery, a quantitative method that defines scenarios as sets of future states of the world in which proposed policies fail to meet their goals.
Given the rewards and penalties associated with characterizing top performance, the ability of statistical benchmarks to summarize key features of the provider performance distribution should be examined.
An overview of the 'mental models' methodology of communicating focuses on each step in the initial approach and offers a discussion of four specific challenges that a practitioner may face when implementing the approach and strategies for addressing them.
Large efficiency gains and substantial reduction in omitted variable bias are demonstrated in an application to sociodemographic differences in the risk of child obesity estimated from two nationally representative cohort surveys.
Modern psychometric methods for scoring the Clinician & Group Consumer Assessment of Healthcare Providers and Systems (CG-CAHPS®) instrument can improve the precision of patient scores.
Upper-extremity and mobility subdomains shared about 35% of the variance in common, and produced comparable scores whether calibrated separately or together.
Although study characteristics, such as trial quality, may explain some proportion of heterogeneity across study results in meta-analyses, residual heterogeneity is a crucial factor in determining when associations between moderator variables and effect sizes can be statistically detected.
Scenario discovery offers a new means to characterize and communicate the information in computer simulation models under conditions of deep uncertainty.
A new set of scenarios, referred to as Shared Socio-economic Pathways (SSPs), examines challenges to mitigation and challenges to adaptation. Developing SSPs with a "backwards" approach could help inform the development of SSPs to ensure the storylines focus on the driving forces most relevant to distinguishing between the SSPs.
Many objective robust decision making (MORDM) combines concepts and methods from many objective evolutionary optimization and robust decision making (RDM), along with extensive use of interactive visual analytics, to facilitate the management of complex environmental systems.
An essential aspect of patient-centered outcomes research (PCOR) and comparative effectiveness research (CER) is the integration of patient perspectives and experiences with clinical data to evaluate interventions.
The Coastal Louisiana Risk Assessment model (CLARA) facilitates comparisons of current and future flood risk under a variety of protection system configurations in a wide range of environmental, operational, and economic uncertainties.
The quality of clinical care and the quality of interpersonal care should be considered separately to give an overall assessment of medical care.
The PTSD Checklist–Civilian Version (PCL-C; Weathers, Litz, Herman, Huska, & Keane, 1993) is used for the identification of posttraumatic stress disorder (PTSD).
Evaluates the equivalence of the PROMIS® physical functioning item bank by language of administration (English versus Spanish).
A computer-based decision-support tool, called the Coastal Protection and Restoration Authority (CPRA) Planning Tool, provided technical analysis that supported the development of Louisiana's 2012 Comprehensive Master Plan for a Sustainable Coast through CPRA and community-based deliberations.
