The Deployment Life Study: Longitudinal Analysis of Military Families Across the Deployment Cycle2016
In 2009, RAND launched the Deployment Life Study to study military family readiness. This report presents analyses on marital relationships, family environment, psychological and behavioral health, child well-being, and military integration.
-
-
Provision of Mental Health Services as a Quality Indicator for Adolescent Substance Abuse Treatment Facilities2014
The study tested whether adolescents receiving substance abuse treatment at facilities offering full or partial mental health services have better 12-month substance use and mental health outcomes than youths at facilities with no mental health services.

-
Assessing Operation Purple: A Program Evaluation of a Summer Camp for Military Youth2012
To help fill the gap in the research on the effectiveness of military family support programs, a RAND study explored the curriculum, themes, and outcomes of Operation Purple, a free weeklong summer camp program for youth with a deployed parent.

Housing Affordability and Health Among Homeowners and Renters 2010
People living in unaffordable housing are more likely to rate their health as poor.

Synthetic Estimation for the Complier Average Causal EffectIn Press
-
-
Collaborative Targeted Learning Using Regression Shrinkage2017
While the underlying theory of collaborative targeted minimum loss-based estimation is quite general, current implementations involve greedy stepwise selection of covariates into the exposure model.
-
-
-
Optimizing Variance-Bias Trade-Off in the TWANG Package for Estimation of Propensity Scores 2017
This discussion highlights potentially meaningful ways to optimize propensity score machine learning methods to allow for minimal bias and less variability.
-
-
A Synthetic Estimator for the Efficacy of Clinical Trials with All-Or-Nothing Compliance 2017
Synthetic estimation is a promising approach when patient noncompliance is affecting a clinical trial.
-
Collaborative Targeted Learning Using Regression Shrinkage 2017
While the underlying theory of collaborative targeted minimum loss-based estimation is quite general, current implementations involve greedy stepwise selection of covariates into the exposure model.
More Than Two Treatment Groups
-
A Tutorial on Propensity Score Estimation for Multiple Treatments Using Generalized Boosted Models 2013
The use of propensity scores to control for pretreatment imbalances on observed variables in non-randomized or observational studies examining the causal effects of treatments or interventions has become widespread over the past decade.
-
Effectiveness of Treatment for Adolescent Substance Use: Is Biological Drug Testing Sufficient? 2014
The purpose of this study was to compare the relative effectiveness of three treatment modalities for adolescent substance use: biological drug screening (BDS), Motivational Enhancement Therapy-Cognitive Behavioral Therapy (MET/CBT5), and BDS combined with MET/CBT5, relative to no treatment.

Estimating the Causal Effects of Cumulative Treatment Episodes for Adolescents Using Marginal Structural Models and Inverse Probability of Treatment Weighting 2014
We use a marginal structural model with inverse-probability-of-treatment weighting to estimate the causal effects of cumulative treatment experiences over a period of 9 months on drug use at the end of 1-year among 2870 adolescents receiving care in community-based treatment settings.

Omitted Variable Work
-
The Relationship Between Urban Sprawl and Coronary Heart Disease in Women 2013
Studies have reported relationships between urban sprawl, physical activity, and obesity, but – to date – no studies have considered the relationship between sprawl and coronary heart disease (CHD) endpoints.
Other Methods Papers
-
-
Landmark Estimation of Survival and Treatment Effects in Observational Studies 2016
Clinical studies aimed at identifying effective treatments to reduce the risk of disease or death often require long term follow-up of participants in order to observe a sufficient number of events to precisely estimate the treatment effect.
-
-
Assessing the Sensitivity of Treatment Effect Estimates to Differential Follow-Up Rates: Implications for Translational Research2012
The authors developed a new tool for assessing the sensitivity of findings on treatment effectiveness to differential follow-up rates in the two treatment conditions being compared.
-
An Application of the Principal Stratification to Control for Institutionalization at Follow-Up in Studies of Substance Abuse Treatment Programs2008
Participants in longitudinal studies on the effects of drug treatment and criminal justice system interventions are at high risk for institutionalization. Use of principal stratification to control for institutionalization at follow-up is evaluated.
-
Interpreting Treatment Effects When Cases Are Institutionalized After Treatment2007
Develops a causal modeling framework for evaluating the standard approaches for addressing the confounding of the effects of ignoring institutionalization of drug treatment clients and other effects, and illustrates the results of each approach.
