Abstract

Although approaches for handling missing data from longitudinal studies are well-developed when the patterns of missingness are monotone, fewer methods are available for non-monotone missingness. Moreover, the conventional missing at random (MAR) assumption -- a natural benchmark for monotone missingness -- does not model realistic beliefs about non-monotone missingness processes (Robins and Gill, 1997). This has provided the impetus for alternative non-monotone missing not at random (MNAR) mechanisms. The "no self-censoring" (NSC) model is such a mechanism and assumes the probability an outcome variable is missing is independent of its value when conditioning on all other possibly missing outcome variables and their missingness indicators. As an alternative to "weighting" methods that become computationally demanding with increasing number of outcome variables, we propose a multiple imputation approach under NSC. We focus on the case of binary outcomes and present results of simulation and asymptotic studies to investigate the performance of the proposed imputation approach. We describe a related approach to sensitivity analysis to departure from NSC. Finally, we discuss the relationship between MAR and NSC and prove that one is not a special case of the other. The proposed methods are illustrated with application to a substance use disorder clinical trial.

Abstract

In many psychometric applications, the relationship between the mean of an outcome and a quantitative covariate is too complex to be described by simple parametric functions; instead, flexible nonlinear relationships can be incorporated using penalized splines. Penalized splines can be conveniently represented as a linear mixed effects model (LMM), where the coefficients of the spline basis functions are random effects. The LMM representation of penalized splines makes the extension to multivariate outcomes relatively straightforward. In the LMM, no effect of the quantitative covariate on the outcome corresponds to the null hypothesis that a fixed effect and a variance component are both zero. Under the null, the usual asymptotic chi-square distribution of the likelihood ratio test for the variance component does not hold. Therefore, we propose three permutation tests for the likelihood ratio test statistic: one based on permuting the quantitative covariate, the other two based on permuting residuals. We compare via simulation the Type I error rate and power of the three permutation tests obtained from joint models for multiple outcomes, as well as a commonly used parametric test. The tests are illustrated using data from a stimulant use disorder psychosocial clinical trial.

Abstract

[Correction Notice: An Erratum for this article was reported in Vol 34(2) of Psychology of Addictive Behaviors (see record 2020-16883-001). In the original article the order of authorship was incorrect. The correct second and third authors should appear instead as Brian Borsari and Jennifer E. Merrill.] Heavy episodic drinking (HED) and depressive symptoms often co-occur among college students and are associated with significant impairment. However, evidence-based treatments for these common co-occurring conditions are not available for college students. The current study compared the effectiveness of a treatment combining Cognitive-Behavioral Therapy for Depression and Brief Motivational Interviewing (CBT-D + BMI) versus Cognitive-Behavioral Therapy for Depression (CBT-D) alone among 94 college students with HED and depressive symptoms. Both treatment programs were associated with significant reductions of similar magnitude in HED, alcohol-related problems (ARP), and depressive symptoms at the end of treatment and at the 1-month follow-up assessment. Moderation analyses indicated that, among college students with fewer depressive symptoms at baseline, CBT-D was associated with greater sustained reduction in heavy drinking relative to CBT-D + BMI at the 1-month follow-up. Although the study did not include a no-treatment condition, the magnitude of improvement during treatment in both groups was greater than what is expected with passage of time. Although clinicians in college counseling centers may lack specialty training for co-occurring conditions, CBT-D is widely implemented in college settings. Our findings suggest that CBT-D may reduce both depressive symptoms and HED in college students and may be used to address a significant public health problem.

Abstract

Background and Objectives: The gender gap in prevalence of substance‐use disorders has narrowed. However, gender differences in stimulant misuse have not been well‐characterized in recent years. The aim of this study was to quantify gender differences in past‐year stimulant misuse and stimulant‐use disorder, separated by stimulant type (cocaine/crack, prescription stimulants, and methamphetamine). In an exploratory aim, we investigated whether gender differences were moderated by age or sexual orientation. Methods: We combined data from the National Survey on Drug Use and Health from 2015 to 2019 (unweighted N = 282,768) to test gender differences in the prevalence of past‐year stimulant misuse. Results: Results indicated that stimulant misuse was significantly more prevalent in men than women for all stimulant types for both past‐year use and past‐year use disorder. The magnitude of this sex difference was smallest for prescription stimulants, where men had 1.37 times higher odds of past‐year misuse and no gender difference was observed in the prevalence of prescription stimulant‐use disorder. The magnitude of gender differences also varied based on both age and sexual orientation. Conclusions and Scientific Significance: Illicit stimulant misuse continues to be more common in men than in women; however, gender differences are more modest for prescription stimulant misuse, suggesting a narrowing of this historical gender difference.
