This study used evidence synthesis to examine treatment effect by demographic and study context factors in clinical trials of CBI for AOD. Methods. Studies w...
Background
Few studies have investigated changes in brain structure and function associated with recovery from cocaine use disorder (CUD), and fewer still have identified brain changes associated with specific CUD treatments, which could inform treatment development and optimization.
Methods
In this longitudinal study, T1-weighted magnetic resonan...
Background/Objectives
There is a great unmet need for accessible adjunctive interventions to promote long-term recovery from substance use disorder (SUD). This study aimed to iteratively develop and test the initial feasibility and acceptability of Mindful Journey, a novel digital mindfulness-based intervention for promoting recovery among individu...
Introduction
Connecting individuals to recovery support services such as recovery community centers and mutual help organizations can be crucial for sustaining recovery from addiction. However, there may be barriers to engagement with recovery support services on individual (e.g., limited motivation) and structural (e.g., limited information on rec...
Background
A strong cooperative bond between the patient and provider (“therapeutic alliance”) is robustly associated with better alcohol use disorder (AUD) treatment outcomes. Although digital treatments for AUD have significant potential, the function of the alliance during digital programs is unclear. We compared the validity of patient‐reported...
Background
Alcohol use disorder (AUD) commonly causes hospitalization, particularly for individuals disproportionately impacted by structural racism and other forms of marginalization. The optimal approach for engaging hospitalized patients with AUD in treatment post-hospital discharge is unknown. We describe the rationale, aims, and protocol for P...
Treatment outcomes for individuals with substance use disorders (SUDs) are variable and more individualized approaches may be needed. Cross-validated, machine-learning methods are well-suited for probing neural mechanisms of treatment outcomes. Our prior work applied one such approach, connectome-based predictive modeling (CPM), to identify dissoci...
Purpose of Review
Impulsivity is considered an important construct in the cycle of addiction, yet the effect of evidence-based treatments on impulsivity is unclear. The goal of this paper was to review the evidence regarding the effect of cognitive behavioral therapy (CBT), one of the most studied psychotherapies for addiction, on measures of impul...
Purpose of Review
Problem gambling can have profound consequences for affected individuals, yet only a small proportion of people with problem gambling seek treatment.

The authors describe the cultural adaptation of an innovative computer-based training for cognitive behavioral therapy program (CBT4CBT). Based in cognitive-behavioral skills training, CBT4CBT utilizes a tel...
Although many studies have examined religiosity as a protective factor for substance use, few have considered its relationship to treatment outcomes among Latinx adults. Using data from 89 individuals participating in a randomized clinical trial evaluating a culturally adapted Spanish-language version of web-based cognitive behavioral therapy (CBT4...
Objective: Clinical trials for substance use disorder (SUD) often assess outcomes by aggregating substance use data into weekly proportions. However, daily substance use patterns may reveal how motivation changes during treatment. Neurocognitive principles of recency and expectancy indicate the salience of treatment mechanisms would increase on day...
Background:
Assessment instruments commonly used in clinical trials to measure functional outcomes in substance users may lack sensitivity to detect change during treatment, potentially limiting findings regarding benefits of reduced drug use. This study evaluated the sensitivity of the Addiction Severity Index (ASI) to detect change in psychiatri...
Background
Computer‐based delivery of cognitive behavioral therapy (CBT) may be a less costly approach to increase dissemination and implementation of evidence‐based treatments for alcohol use disorder (AUD). However, comprehensive evaluations of costs, cost‐effectiveness, and cost–benefit of computer‐delivered interventions are rare.

Background
Cognitive‐behavioral therapy (CBT) has long‐standing evidence for efficacy in the treatment of alcohol use, yet implementation in clinical practice has been challenging. Delivery of CBT through technology‐based platforms, such as web‐based programs and mobile applications, has the potential to provide widespread access to this evidence‐b...
There is a critical need for research on clinical features that may influence response to treatment for opioid use disorder (OUD). Given its neurobiology and relevance to opioid use, anhedonia may be one such promising clinical feature. We identified and reviewed 11 studies that measured anhedonia in humans with OUD to characterize the current stat...
Background
Unemployment is a chronic problem among treatment seeking substance users and is associated with poor treatment response. Most studies that have examined the relationship between employment and treatment outcomes for substance use disorders have done so by considering employment at only one specific point in time (e.g., upon entering tre...
Background
Most published treatment trials for cocaine use disorders (CUD) have been conducted with samples composed predominantly of White men and underrepresent women and racial/ethnic minorities. Because of the high prevalence of men and White individuals in CUD treatment trials, results from studies that have compared treatment outcomes by gend...
Objective:
Abstinence outcomes are typically prioritized in the treatment of cocaine use disorder while ignoring patterns of low-frequency cocaine use. This study examined patterns of cocaine use frequency during treatment and evaluated how these patterns related to baseline characteristics and functioning outcomes 6 and 12 months after treatment....
Cognitive-behavioral therapy (CBT) is one of the most evaluated behavioral interventions for substance use disorders, with considerable empirical evidence supporting its efficacy. However, despite CBT’s strong support from efficacy trials, broad dissemination and implementation have been challenging. Furthermore, there remains limited understanding...
Background
Substantial efforts have been made to identify clinically meaningful non-abstinence cocaine use outcomes by establishing associations between targeted drug use outcomes and long-term functional improvements. Psychiatric symptomatology is prevalent among those seeking treatment for cocaine use disorder (CUD). Establishing an association b...
Commentary to: What defines a clinically meaningful outcome in the treatment of substance use disorders: reductions in direct consequences of drug use or improvement in overall functioning?
Background:
The theoretical benefits of naltrexone as a treatment for opioid use disorder (e.g., safety, non-addictive, low risk of diversion) stand in sharp contrast to its disappointing record on retention in most samples. The relationship of uncomfortable physical and dysphoric symptoms to retention on naltrexone is a controversial and under-st...
Objectives:

Cognitive remediation (CR) has been found to improve cognitive performance among adults with schizophrenia in randomized controlled trials (RCTs). However, improvements in cognitive performance are often observed in the control groups of RCTs as well. There has been no comprehensive examination of change in control groups for CR, which may inform t...
A substantial portion of individuals entering treatment for substance use have been referred by the criminal justice system, yet there are conflicting reports regarding treatment engagement and outcome differences compared to those not referred. This study examined baseline characteristic and treatment outcome differences among cocaine-dependent in...
The limited role of therapists in some technology-based interventions raises questions as to whether clients may develop a ‘working alliance’ with the program, and the impact on relationships with a therapist and/or treatment outcomes. In this study, the Working Alliance Inventory (WAI), and an adapted version for technology-based interventions (WA...
Background
Selection of an appropriate indictor of treatment response in clinical trials is complex, particularly for the various illicit drugs of abuse. Most widely-used indicators have been selected based on expert group recommendation or convention rather than systematic empirical evaluation. Absence of an evidence-based, clinically meaningful i...
Objective:
Cocaine users often present to treatment with a multitude of problems typically considered addiction related; however, there is little evidence that reductions in cocaine use are followed by reductions in these problems. This study evaluated the relationship between rates of cocaine use during treatment and the level of non-cocaine life...
Objective:
A previous pilot trial evaluating computer-based training for cognitive-behavioral therapy (CBT4CBT) in 77 heterogeneous substance users (alcohol, marijuana, cocaine, and opioids) demonstrated preliminary support for its efficacy in the context of a community-based outpatient clinic. The authors conducted a more definitive trial in a la...
After decades of defining which behavioral treatments are effective for treating addictions, the focus has shifted to exploring how these treatments work, how best to disseminate and implement them in the community, and what underlying factors can be manipulated in order to increase the rates of treatment success. These pursuits have led to advance...
Smoking cocaine achieves maximal concentration and effect far more rapidly than through the intranasal ("snorting") route, and it is associated with greater propensity for dependence and more severe consequences. However, very little is known about differences in treatment outcome according to route of administration. This study compared treatment...
Cognitive behavioral therapy for illegal drug use has its roots in behavior theory, incorporating principles of classical and operant conditioning toward understanding patterns of substance use, while also emphasizing the importance of a person's thoughts and feelings as contributors to behavior.
