Application of Causal Forest Model to Examine Treatment Effect Heterogeneity in Substance Use Disorder Psychosocial Treatments.

Objectives: Heterogeneity of treatment effect (HTE) is a concern in substance use disorder (SUD) treatments but has not been rigorously examined. This exploratory study applied a causal forest approach to examine HTE in psychosocial SUD treatments, considering multiple covariates simultaneously.

Methods: Data from 12 randomized controlled trials of nine psychosocial treatments were obtained from the National Institute on Drug Abuse Clinical Trials Network.

Objective socioeconomic status, subjective social status, and mental disorders in Iranian mental health survey (IranMHS): A mediation analysis.

Background: There is ample evidence that socioeconomic status, objectively quantified by tangible resources, impacts mental health outcomes. However, the psychosocial mechanism linking objective socioeconomic status (OSS) with mental health is not clear. This study examined to what extent associations between OSS and the twelve-month prevalence of mental disorders, are mediated by the individual perception of social conditions-the subjective social status (SSS).

Medicaid expansion and medications to treat opioid use disorder in outpatient specialty care from 2010 to 2020.

This study examined whether there were changes in MOUD use within outpatient admissions to specialty treatment facilities in Medicaid expansion states beyond the initial expansion period.
