The relative impact of nicotine dependence, other substance dependence, and gender on Bechara Gambling Task performance.

Individuals with substance use disorders (SUDs) tend to focus more on immediate, rather than cumulative, consequences of their actions on measures of decision-making. This type of decision-making may contribute to continued substance use. The present study compared the performance of four groups of individuals on one measure of decision-making, the Bechara Gambling Task (BGT). The groups were (a) heavy smokers with comorbid substance dependence (n = 40), (b) heavy smokers with no history of substance dependence (n = 19), (c) substance dependent never smokers (n = 26), and (d) never smokers with no history of substance dependence (n = 34). Analysis revealed that there were no significant main effects of gender or SUD status. However, a significant gender by SUD status interaction was found, such that men with an SUD performed more poorly on the BGT than men without an SUD history. Women with and without an SUD both performed poorly on this task. Unexpectedly, no differences in BGT performance were found between smokers and nonsmokers. Overall, findings indicate that having an SUD, other than nicotine dependence, is correlated with poor BGT performance in men only. The BGT did not differentiate between women with and without SUDs, and therefore, may not be an appropriate measure of decision-making in women.

Detection of youth at high risk for substance use disorders: A longitudinal study.

This study extends prior research (D. Clark, J. Cornelius, L. Kirisci, & R. Tarter, 2005) by determining whether variation in the developmental trajectories of liability to substance use disorder (SUD) is contributed by neurobehavioral disinhibition, parental substance use involvement, and demographic variables. The sample, participants in a long-term prospective investigation, consisted of 351 boys, evaluated at ages 10-12, 12-14, 16, 19, and 22, whose parents either had SUD or no adult psychiatric disorder. Neurobehavioral disinhibition in childhood, in conjunction with parental lifetime substance use/SUD, place the child at very high risk for SUD by age 22 if psychosocial maladjustment progresses in severity in early adolescence. These results indicate that monitoring social adjustment during the transition from childhood to mid-adolescence is important for identifying youth at very high risk for succumbing to SUD by young adulthood.

Modeling the pathways linking childhood hyperactivity and substance use disorder in young adulthood.

This study modeled direct and mediated pathways linking childhood hyperactivity and substance use disorder (SUD). Boys (n = 112) were administered the revised Drug Use Screening Inventory at age 12-14 years and the Structured Clinical Interview for DSM-IV at age 22 years. Six newly derived scales having established heritability were conceptually organized into internalizing and externalizing pathways to SUD emanating from childhood hyperactivity. Hyperactivity directly predicts SUD. Neuroticism, conduct problems, and their respective manifestations of social withdrawal and school problems mediated the association between hyperactivity and SUD. Hyperactivity also predicted neuroticism that, in turn, predicted low self-esteem leading to social withdrawal and SUD. These results indicate that hyperactivity is a diathesis for both internalizing and externalizing disturbances that, in turn, portend differential expression of psychosocial maladjustment presaging SUD.

Contracting, prompting, and reinforcing substance use disorder continuing care: A randomized clinical trial.

Although continuing care is strongly related to positive treatment outcomes for substance use disorder (SUD), participation rates are low and few effective interventions are available. In a randomized clinical trial with 150 participants (97% men), 75 graduates of a residential Veterans Affairs Medical Center SUD program who received an aftercare contract, attendance prompts, and reinforcers (CPR) were compared to 75 graduates who received standard treatment (STX). Among CPR participants, 55% completed at least 3 months of aftercare, compared to 36% in STX. Similarly, CPR participants remained in treatment longer than those in STX (5.5 vs. 4.4 months). Additionally, CPR participants were more likely to be abstinent compared to STX (57% vs. 37%) after 1 year. The CPR intervention offers a practical means to improve adherence among individuals in SUD treatment. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Two-year posttreatment functioning and coping of substance abuse patients with posttraumatic stress disorder.

The 2-year posttreatment course of substance abuse patients with posttraumatic stress disorder (PTSD) was examined in a multisite evaluation of Veterans Affairs substance abuse treatment. Substance abuse patients with PTSD (SUD-PTSD) were compared with patients with only substance use disorder (SUD only) and patients with other comorbid psychiatric diagnoses (SUD-PSY) on outcomes during the 2 years after treatment. SUD-PTSD patients had a poorer long-term course on substance use, psychological symptom, and psychosocial outcomes than SUD-only and SUD-PSY patients. Coping methods were examined as mediators of the effect of PTSD on substance use outcomes. Greater use of avoidance coping styles and less use of approach coping at 1 year partially accounted for the association of PTSD with 2-year substance use. Treatments that address multiple domains of functioning and focus on alternative coping strategies are recommended for this population.

How should we revise diagnostic criteria for substance use disorders in the DSM-V?

This article reviews literature on the validity and performance characteristics of the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 1994) diagnostic criteria for substance use disorders (SUDs) and recommends changes in these criteria that should be considered for the next edition of the DSM (DSM-V). Substantial data indicate that DSM-IV substance abuse and substance dependence are not distinct categories and that SUD criteria are best modeled as reflecting a unidimensional continuum of substance-problem severity. The conceptually and empirically problematic substance abuse diagnosis should be abandoned in the DSM-V, with substance dependence defined by a single set of criteria. Data also indicate that various individual SUD criteria should be revised, dropped, or considered for inclusion in the DSM-V. The DSM-V should provide a framework that allows the integration of categorical and dimensional approaches to diagnosis. Important areas for further research are noted.

Maternal psychosocial factors associated with substance use in Mexican-origin and African American low-income pregnant women

PURPOSE: To describe ethnic-specific patterns of substance use before and during pregnancy in low-income pregnant women, examine the associations between psychosocial factors and patterns of substance use within ethnic groups, and assess maternal sociodemographic, prenatal, and psychosocial factors of women who continue to use substances during pregnancy and those who do not. METHOD: A prospective study of low-income, primiparous African American (n = 255), Mexican American (n = 525), and Mexican immigrant (n = 764) women was conducted in 22 prenatal care clinics in Los Angeles, CA. Data were collected in face-to-face interviews in both English and Spanish on prenatal life events, anxiety, sources of support, and substance use behaviors three months before and during pregnancy. FINDINGS: Significant ethnic differences were found in use of alcohol, cigarettes, and illicit drugs. African American women were more likely than Mexican-origin women to report use of substances before and during pregnancy. Mexican American women were more likely than Mexican immigrant women to report use of substances before and during pregnancy. Women who continued to use substances during pregnancy were less likely to be living with the baby's father, to have planned the pregnancy, to report having been able to go for prenatal care as soon as they wanted, and more likely to be identified at medical risk. CONCLUSIONS: Providers must increase the assessment and monitoring of substance use behaviors of low-income women in prenatal care settings. The role of health care providers must encompass advocacy and public health education.     

Are gender differences in post-traumatic stress disorder rates attenuated in substance use disorder patients?

We review 15 studies that examined rates of post-traumatic stress disorder (PTSD) in substance use disorder (SUD) patients to determine whether the typical female-greater-than- male gender difference in PTSD rates is attenuated in SUD samples. Since the majority of studies reviewed did not find a gender difference in PTSD rates, we critically examined methodological factors that might account for this attenuation, but none appeared to completely account for the variability in detection of gender differences across studies. Several factors may contribute to making rates of PTSD among SUD males equivalent to the high rates observed in SUD females: 1) the risky lifestyle associated with men's substance abuse may increase their exposure to traumatic events, 2) a history of more severe trauma characteristics may be apparent among men with SUDs, or 3) attenuated gender differences in rates of other comorbidities that increase PTSD risk (e.g., depression) may exist. Clinical implications are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

UNC-73 activates the Rac GTPase and is required for cell and growth cone migrations in C. elegans

Posttraumatic stress disorder (PTSD) is a common co-occurring diagnosis in patients with substance use disorders (SUDs). Despite the documented prevalence of this particular "dual diagnosis," relatively little is known about effective treatment for SUD-PTSD patients. This article reviews empirical research on the course and treatment of SUD-PTSD comorbidity and highlights clinically relevant findings. Based on this review, the following is noted: PTSD is highly prevalent in SUD patients, consistently associated with poorer SUD treatment outcomes, and related to distinct barriers to treatment. Specific treatment practices are recommended for substance abuse treatment providers: (a) All patients should be carefully screened and evaluated for trauma and PTSD; (b) referrals should be provided for concurrent treatment of SUD-PTSD, if available, or for psychological counseling with the recommendation that trauma/PTSD be addressed; and (c) increased intensity of SUD treatment should be offered in conjunction with referrals for family treatment and self-help group participation.     

Phosphorus-31 magnetic resonance brain spectroscopy of children at risk for a substance use disorder: preliminary results

The purpose of this exploratory investigation was to evaluate the heuristic potential of 31P magnetic resonance spectroscopy (MRS) in elucidating a neurobiologic component of the liability for a substance use disorder (SUD). We investigated 31P MRS spectra employing chemical shift imaging (CSI) derived from four distinct anatomic brain locations (i.e. frontal, occipital, right parietal, left parietal) in three groups of peripubertal children who are hypothesized to be at increasing levels of familial SUD risk. Specifically, we studied children with a positive paternal family history of SUD and a disruptive behavior disorder (DBD) diagnosis (SUD+/DBD+; n = 10), in contrast, to those with a positive paternal SUD history in the absence of other psychopathology (SUD+/DBD-; n = 13) and matched control children from normal families (SUD-/DBD-; n = 13). In addition, we examined neurocognitive tests of our subjects to determine any associations between cognitive capacities with regional 31P MRS spectra. The highest-risk sample (SUD+/DBD+) demonstrated a diminished proportion of phosphodiesters confined to the right parietal voxel. This right parietal phosphodiester proportion correlated only with the Information Scale score on a standard intelligence test for children. This suggested a relationship between general learning ability and motivation for academic achievement and right parietal physiology in the highest-risk sample. Variations in synaptic pruning could account for this observation.     

PTSD treatment and 5-year remission among patients with substance use and posttraumatic stress disorders.

Given the high prevalence of comorbid substance use and posttraumatic stress disorders (SUD-PTSD), how to best treat these patients is a pressing concern for SUD providers. PTSD treatment may play an important role in patients' recovery. One hundred male SUD-PTSD patients who attended SUD treatment completed 1-, 2-, and 5-year follow-ups. Outpatient treatment information was gathered from Veterans Affairs databases. PTSD treatment and 12-Step group attendance in the 1st year predicted 5-year SUD remission. Patients who received PTSD treatment in the first 3 months following discharge and those who received treatment for a longer duration in Year 1 were more likely to be remitted in Year 5. The receipt of PTSD-focused treatment immediately after SUD treatment may enhance long-term remission. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Spiritual Transcendence as a Predictor of Psychosocial Outcome From an Outpatient Substance Abuse Program.

Does the Spiritual Transcendence Scale (STS; R. L. Piedmont, 1999) predict psychosocial outcomes from an outpatient substance abuse program? Self-report data on symptoms, personality, and coping resources were obtained for 73 consecutive admissions (57 men and 16 women; ages 19-66 years) at intake and again from the 56 (47 men and 9 women) who completed treatment. Controlling for relevant demographic variables, pretreatment STS scores were significantly related to self-ratings at posttreatment. The STS predicted treatment outcomes over and above the contribution of the five-factor model of personality. Significant partial correlations between pretreatment STS scores and therapist ratings of treatment outcome were also obtained. Spiritual Transcendence, especially the facets of Universality and Connectedness, appears to play a significant role in substance abuse recovery.

Couples- versus individual-based therapy for alcohol and drug abuse: Effects on children's psychosocial functioning.

The study compared the effect of couples-based vs individual-based therapy for men who entered outpatient substance abuse treatment on the psychosocial functioning of children in their homes. Men were randomly assigned to (1) behavioral couples therapy (BCT), (2) individual-based treatment (IBT) or (3) couples-based psychoeducational attention control treatment (PACT). For both children of alcohol (N=71) and drug-abusing men (N=64), parents' ratings of children's psychosocial functioning was higher for children whose fathers participated in BCT at posttreatment and at 6- and 12-mo follow-up than for children whose fathers participated in IBT or PACT. BCT resulted in greater improvements in parents' dyadic adjustment and fathers' substance use. Thus, couples-based intervention that addresses both issues may have greater benefits for children in these homes. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Stressful life events, gender, and substance use: An application of tobit regression.

Extended research on stressful life events (SLEs) and substance use by examining gender differences in the relationship between SLEs and the use of 4 substances, determining whether SLEs were uniquely related to each type of substance use, and using tobit regression analysis to increase statistical conclusion validity. Data were obtained from 606 men and 1,001 women (all Ss aged 19–65 yrs) who were interviewed and responded to a questionnaire. Analyses revealed that the magnitude of the positive relationship between SLEs and cigarette use did not differ across men and women, whereas SLEs were unrelated to illicit drug use among both men and women. In contrast, SLEs were more strongly related to alcohol use among men, whereas they were more strongly related to psychotherapeutic drug use among women.

The impact of minority stress on mental health and substance use among sexual minority women.

Objective: We examined the direct and indirect impact of minority stress on mental health and substance use among sexual minority women. Method: A combination of snowball and targeted sampling strategies was used to recruit lesbian and bisexual women (N = 1,381) for a cross-sectional, online survey. Participants (M age = 33.54 years; 74% White) completed a questionnaire assessing gender expression, minority stressors (i.e., victimization, internalized homophobia, and concealment), social–psychological resources (i.e., social support, spirituality), and health-related outcomes. We used structural equation modeling to test associations among these factors, with gender expression as an antecedent and social–psychological resources as a mediator between minority stress and health. Results: The final model demonstrated acceptable fit, χ2(79) = 414.00, p confirmatory fit index = .93, Tucker–Lewis index = .91, standardized root-mean-square residual = .05, root-mean-square error of approximation = .06, accounting for significant portions of the variance in mental health problems (56%) and substance use (14%), as well as the mediator social–psychological resources (24%). Beyond indirect effects of minority stress on health outcomes, direct links emerged between victimization and substance use and between internalized homophobia and substance use. Conclusions: Findings indicate a significant impact of minority stressors and social–psychological resources on mental health and substance use among sexual minority women. The results improve understanding of the distinct role of various minority stressors and their mechanisms on health outcomes. Health care professionals should assess for minority stress and coping resources and refer for evidence-based psychosocial treatments.

Changes in neuropsychological functioning over 10 years following adolescent substance abuse treatment.

Previously, Anderson, Ramo, Cummins, and Brown (2010) described six distinct patterns of alcohol and other drug (AOD) use during the decade following adolescents' treatment for alcohol and other substance use disorders (A/SUD). This time period represents a phase of significant neurodevelopment, and the influence of substance use on the brain is a concern. In the present study, we examined patterns of neuropsychological function over these 10 years in relation to the AOD trajectories identified for youth as they transition into their twenties. Participants were part of a longitudinal research project following adolescents with and without A/SUD who received neuropsychological examinations at baseline and up to 7 times thereafter spanning 10 years (N = 213; 46% female at baseline). Neuropsychological trajectories were significantly related to substance involvement patterns over time on measures of verbal learning and memory (ps = .011 to p = .0002), and verbal attention/working memory (p = .020), with heavier use patterns generally followed by poorer cognition. Heavy use of alcohol alone was independently associated with poorer verbal memory over time. Furthermore, substance withdrawal symptoms during each follow-up time point were related to poorer verbal learning and memory scores (ps     

An investigation into the observed sex difference in prevalence of unipolar depression.

The rates of occurrence of unipolar depression as measured by self-report and by diagnosis based on semistructured interviews were examined in a longitudinal study with 312 men and 686 women aged 18 yrs and over. Number of new cases, average age of onset, and average duration of episodes were comparable in men and women, but women with a history of previous depression were much more likely to become depressed again than men with a similar history. Data on a large number of demographic and psychological variables were collected through such measures as the Brief Symptom Inventory. Controlling for these factors (both singly and in combination) did not eliminate the sex difference in unipolar depression. Neither the artifact hypothesis (according to which the "true" prevalence of depression is equal for men and women) nor the psychosocial hypothesis (according to which women are more disadvantaged on relevant psychosocial variables) was supported.

Dental fear treatment outcomes for substance use disorder patients

In order to examine the clinical treatment outcome for dental fears, we compared the records of 18 phobics who had co-morbid substance use disorder (SUD) with those of 27 subjects who were phobic without concomitant SUD. Outcomes were determined by calculation of changes in the Dental Fear Survey (DFS) score. Subjects were classified by the Structured Clinical Interview for DSM-III-R. All subjects received exposure-based behavioral therapy with or without pharmacological adjuncts. All 27 subjects in the non-SUD group and 15 of 18 (83.3%) of subjects in the SUD group improved. Non-SUD subjects improved more than SUD's on the avoidance and specific fear, but not on the physiological upset, dimensions of the DFS.     

Does comorbid substance use disorder exacerbate borderline personality features? A comparison of borderline personality disorder individuals with vs. without current substance dependence.

There is compelling evidence that comorbid borderline personality disorder (BPD) negatively impact the clinical courses and outcomes of substance use disorders (SUD). Conversely, there is little evidence that concurrent SUD exacerbates the clinical characteristics of BPD. Thus, this study sought to examine whether the presence of current substance dependence among BPD patients would be associated with stronger BPD-relevant personality traits and behavioral characteristics. Female BPD patients without (BOR; n = 37) or with current substance dependence (BSUD; n = 19), and female non-BPD/SUD controls (CON; n = 48) were compared with respect to impulsivity, affective lability, affective intensity, externalizing behaviors, and self-harming/suicidal tendencies, taking into consideration their comorbid mood disorders, anxiety disorders, and antisocial personality disorder. Results indicated that both BOR and BSUD groups scored higher than CON in most of the measures, but BOR and BSUD failed to reveal significant group differences especially when the influence of comorbid psychopathology was removed. The overall pattern of findings remained identical even when comparing BPD patients with versus without the diagnosis of lifetime substance dependence. Our results do not support the notion that BPD individuals with SUD display more severe BPD features than individuals with BPD alone.

Substance-dependent, conduct-disordered adolescent males: severity of diagnosis predicts 2-year outcome

Most delinquent youths have conduct disorder (CD), often with comorbid substance use disorder (SUD), attention-deficit/hyperactivity disorder (ADHD) and depression. Some youths' conduct problems later abate, while those of others persist into adult antisocial personality disorder. Earlier CD onset and ADHD reportedly predict persisting antisocial problems, but predictors of persisting SUD are poorly understood. Males aged 13-19 years (n = 89), most referred by criminal justice and social service agencies, received residential treatment for comorbid CD and SUD. They had diagnostic assessments for SUD at intake and for CD, ADHD, and depression (as well as drug-use assessments) at intake and 6, 12 and 24 months later. At intake nearly all had DSM-III-R substance dependence (usually on alcohol and marijuana) and CD with considerable violence and criminality. The 2-year follow-ups revealed improvements in criminality, CD, depression and ADHD, but substance use remained largely unchanged. Various aspects of conduct, crime and substance outcomes at 2 years were predicted by intake measures of intensity of substance involvement, and by CD severity and onset age, but not by severity of either ADHD or depression, nor by treatment duration. Earlier CD onset, more severe CD and more drug dependence predicted worse outcomes, supporting the validity of these diagnoses in adolescents.
