Objectives: Concerns about the cognitive adverse effects of electroconvulsive therapy (ECT) are common among recipients of the treatment despite its relatively small adverse effects on cognitive functioning. Interventions aimed at remediating or improving coping with cognitive adverse effects of ECT have not been developed. The Enhancing Cognitive Domains after ECT (ENCODE) program is a new group intervention aimed at teaching self-management strategies to cope with the cognitive challenges and associated anxiety that often accompanies ECT.

Cognitive training and remediation interventions are well suited to fill the gap for managing cognitive deficits in SUD. We aimed to reach consensus on recommendations for developing and applying these interventions.

Objectives: This study examined the clinical utility of an alcohol and other drug refusal skills intervention designed to be cognitively accessible to adults with ID METHODS: Thirty individuals at high risk for or in recovery from a SUD in developmental disability services (DDS) community residential and day habilitation settings participated in the two-week refusal skills group. Measures included pretest versus posttest improvement in refusal skill competency and baseline performance on a standardized verbal learning test.
Background: Researchers are increasingly investigating therapeutic response associated with new patient subgroups as a way to improve electroconvulsive therapy (ECT) treatment outcomes and reduce adverse events. This study is the first to examine baseline cognitive impairment status as a predictor of clinical outcome in first acute-course ECT patients.
Methods: Baseline cognitive function at various thresholds and serial depressive symptom severity data from first-time ECT patients were examined using generalized linear mixed-effects models.
Background: Striatal neuroadaptations are regarded to play an important role in the progression from voluntary to compulsive use of addictive substances and provide a promising target for the identification of neuroimaging biomarkers. Recent advances in surface-based computational analysis enable morphological assessment linking variations in global and local striatal shape to duration and magnitude of substance use with a degree of sensitivity that exceeds standard volumetric analysis.
Methods: This study used a new segmentation methodology coupled with local surface-based indices of surface area and displacement to provide a comprehensive structural characterization of the striatum in 34 patients entering treatment for substance use disorder (SUD) and 49 controls, and to examine the influence of recent substance use on abnormal age-related striatal deformation in SUD patients.
Background: The Geriatric Depression Scale, Short Form (GDS-15) is a widely-used depression rating scale for elderly adults. It might be useful for persons across the adult lifespan, but more research is needed to support its clinical utility with young and middle-aged adults.
Methods: We examined the classification accuracy of the GDS-15 in identifying depression cases and non-cases in adults aged 18-54 (n = 199) compared to those aged 55-80 (n = 112), using the standard cutoff score of 5.
Fundamental to cognitive models of addiction is the gradual strengthening of automatic, urge-related responding that develops in tandem with the diminution of self-control-related processes aimed at inhibiting impulses. Recent conceptualizations of addiction also include a third set of cognitive processes related to self-awareness and superordinate regulation of self-control and other higher brain function. This review describes new human research evidence and theoretical developments related to the multicausal strengthening of urge-related responding and failure of self-control in addiction, and the etiology of disrupted self-awareness and rational decision-making associated with continued substance use.

This study investigated cognitive and psychomotor performance in 51 methadone maintenance patients (MMP) as a function of time since last methadone dose and maintenance dose level. MMP maintained on doses ranging from 40 to 200 mg (mean = 97 mg) completed a battery of psychomotor and cognitive measures across 2 sessions, during peak and trough states, in a double-blind crossover design.

Method: A convenience sample of 385 non-treatment-seeking adult cannabis smokers (58% male, age 16-64years at start of quit attempt) who made a "serious" (self-defined) quit attempt without formal treatment while not in a controlled environment were administered the 176-item Marijuana Quit Questionnaire (MJQQ) to assess their motivations to quit and outcome of the quit attempt.
Background And Objectives: Neuropsychological impairment among patients with substance use disorders (SUDs) contributes to poorer treatment processes and outcomes. However, neuropsychological assessment is typically not an aspect of patient evaluation in SUD treatment programs because it is prohibitively time and resource consuming. In a previous study, we examined the concurrent validity, classification accuracy, and clinical utility of a brief screening measure, the Montreal Cognitive Assessment (MoCA), in identifying cognitive impairment among SUD patients.

Method: A convenience sample of 384 adult, non-treatment-seeking lifetime cannabis smokers provided retrospective self-report data on their "most difficult" quit attempt without formal treatment, which was used in this secondary analysis.
Background: Cannabis withdrawal can be a negative reinforcer for relapse, but little is known about its association with demographic characteristics.
Objectives: Evaluate the association of demographic characteristics with the experience of cannabis withdrawal.
Methods: Retrospective self-report of a "serious" cannabis quit attempt without formal treatment in a convenience sample of 104 non-treatment-seeking, adult cannabis smokers (mean age 35 years, 52% white, 78% male) with no other current substance use disorder (except tobacco) or chronic health problems.
Background: Cocaine users not seeking treatment have increased regional brain mu-opioid receptor (mOR) binding that correlates with cocaine craving and tendency to relapse. In cocaine-abusing outpatients in treatment, the relationship of mOR binding and treatment outcome is unknown.
Methods: We determined whether regional brain mOR binding before treatment correlates with outcome and compared it with standard clinical predictors of outcome.

Background: Cannabis withdrawal is not recognized in DSM-IV because of doubts about its clinical significance.
Objectives: Assess the phenomenon of cannabis withdrawal and its relationship to relapse in non-treatment-seeking adults.
Subjects: Convenience sample of 469 adult cannabis smokers who had made a quit attempt while not in a controlled environment.
Most treatment studies of opioid-dependent populations have focused predominantly on heroin users, despite a recent increase in those dependent upon prescription opioids. A key methodological challenge involved in studying the latter group involves defining the population. Specifically, researchers must decide whether to include (1) concurrent heroin users and (2) individuals with pain.
View Article and Find Full Text PDFTreatment research with opioid-dependent populations has not traditionally distinguished between those dependent on prescription opioids versus dependent upon heroin. Evidence suggests there is a substantial subpopulation of individuals with opioid dependence resulting largely or exclusively from prescription opioid use. Because this subpopulation may respond to treatment differently from heroin users, a method for discriminating DSM-IV opioid dependence due to prescription opioid use would provide more precision when examining this population.

To date, there has not been a time-efficient and resource-conscious way to identify cognitive impairment in patients with substance use disorders (SUDs). In this study, we assessed the validity, accuracy, and clinical utility of a brief (10-min) screening instrument, the Montreal Cognitive Assessment (MoCA), in identifying cognitive impairment among patients with SUDs. The Neuropsychological Assessment Battery-Screening Module, a 45-min battery with known sensitivity to the mild to moderate deficits observed in patients with SUDs, was used as the reference criterion for determining agreement, rates of correct and incorrect decision classifications, and criterion-related validity for the MoCA.

This study compares the frequencies of retrospective self-reported HIV high-risk drug use and sexual behaviors in 127 out-of-treatment injection drug users using the HIV Risk Questionnaire (HRQ) across two administration methods: (a) a brief standard quantity-frequency approach covering the past 30 days and (b) a lengthier timeline follow-back (TLFB) procedure for improving recall. The two procedures produced similar frequencies of risk behavior across most items (80%) and good intra- and interclass correlation coefficients. The TLFB, however, resulted in higher frequencies for two risk behavior questions-sharing of any drug injection equipment and having any type of unprotected sex.

View Article and Find Full Text PDFBackground: The Marijuana Craving Questionnaire (MCQ) is a valid and reliable, 47-item self-report instrument that assesses marijuana craving along four dimensions: compulsivity, emotionality, expectancy, and purposefulness. For use in research and clinical settings, we constructed a 12-item version of the MCQ by selecting three items from each of the four factors that exhibited the greatest within-factor internal consistency (Cronbach's alpha coefficient).
Methods: Adult marijuana users (n=490), who had made at least one serious attempt to quit marijuana use but were not seeking treatment, completed the MCQ-Short Form (MCQ-SF) in a single session.
Rationale: Cocaine users have increased regional brain mu-opioid receptor (mOR) binding which correlates with cocaine craving. The relationship of mOR binding to relapse is unknown.
Objective: To evaluate regional brain mOR binding as a predictor of relapse to cocaine use is the objective of the study.
Background: Cocaine lengthens electrocardiographic QTc, QRS and PR intervals through blockade of sodium and potassium channels, but changes during withdrawal have not been well studied.
