Rapid cognitive screening of patients with substance use disorders.

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. Classification accuracy of the MoCA, based on receiver operating characteristic (ROC) analysis, was strong, with an area under the ROC curve of 0.86, 95% confidence interval [0.75, 0.97]. The MoCA also showed acceptable sensitivity (83.3%) and specificity (72.9%) for the identification of cognitive impairment. Using a cutoff of 25 on the MoCA, the overall agreement was 75.0%; chance-corrected agreement (kappa) was 41.9%. These findings indicate that the MoCA provides a time-efficient and resource-conscious way to identify patients with SUDs and neuropsychological impairment, thus addressing a critical need in the addiction treatment research community.

Prevalence and implications of perinatal substance use in Missouri

A study was conducted to determine the prevalence of perinatal substance use in Missouri. The population sample studied was selected according to a multi-stage probability-proportional-to-size sampling. The weighted prevalence for perinatal exposure to alcohol, tobacco or illicit substances was 31.9%, 10.8% for illicit substances, 21.9% for tobacco use, and 7.9% for self-reported alcohol use. In 1993, an estimated 23,925 perinatal exposures to licit and illicit substances occurred.     

Attention deficit hyperactivity disorder (ADHD) is associated with early onset substance use disorders

We evaluated the association between attention deficit hyperactivity disorder (ADHD) and the age of onset of psychoactive substance use disorders (PSUD) in adults with ADHD. We hypothesized that ADHD and psychiatric comorbidity would be risk factors for early onset PSUD. We compared 120 referred adults having a clinical diagnosis of childhood-onset ADHD with 268 non-ADHD adults. All diagnoses were obtained using DSM-III-R based structured psychiatric interviews. We used group comparisons of age at onset and Cox proportional hazard models to examine the development of PSUD over time. ADHD was associated with earlier onset of PSUD independently of psychiatric comorbidity. Conduct and juvenile bipolar disorders conferred a significantly increased risk for early onset PSUD independently of ADHD. Psychiatric disorders commonly emerged before the onset of PSUD in both groups. Persistent ADHD with and without psychiatric comorbidity was associated with adolescent onset PSUD. In addition, comorbidity with conduct and juvenile bipolar disorders predicted very early onset PSUD in both ADHD and non-ADHD individuals. These findings confirm and extend previous findings documenting important associations between PSUD and psychiatric comorbidity including persistent ADHD.     

Parents and families as contexts for the development of substance use and substance use disorders.

Parenting and familial influences on substance use and substance use disorders (SUDs) are important areas of study both for theories of etiology and for the development of preventive and treatment interventions. The articles in this special section illustrate both the value and the challenges of studying parenting and familial influences. Noteworthy issues include the need for mediational and moderational models examining the processes by which familial influences operate in a longitudinal framework to consider outcomes in a developmental context. Future directions include a multidisciplinary expansion of these studies. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Personality and substance use disorders: II. Alcoholism versus drug use disorders.

The relationship between personality and substance use disorders was investigated in a community-based sample of 638 individuals who were alcoholic and/or had a drug use disorder, and 1,530 individuals who did not have a substance use disorder. Personality was assessed by the Multidimensional Personality Questionnaire; substance use diagnoses were based on standard criteria as assessed by interview. Data were analyzed using a 3-factor (Gender?×?Alcoholism?×? Drug Use Disorder) multivariate analysis of variance. The significant alcoholism main effect was associated primarily with negative emotionality, whereas the significant drug use disorder main effect was associated primarily with constraint. No significant interactions with gender were observed. These findings suggest that the elevated levels of behavioral disinhibition observed with alcoholic individuals may be attributable to a subset of alcoholic individuals who also abuse drugs other than alcohol.

Personality disorders in adolescents with major depression, substance abuse disorders, and coexisting major depression and substance use disorders.

This study examined the presence of personality disorders in adolescent inpatients with major depression (MDD; n?=?45), substance use disorders (SUD; n?=?27), or both disorders combined (MDD-SUD; n?=?42). A consecutive series of patients were given structured diagnostic interviews for Axes I and II disorders. The groups did not differ with regard to age, gender, ethnicity, socioeconomic status, psychiatric history, or global assessment of functioning. Borderline personality disorder was diagnosed more frequently in the MDD-SUD group than in the MDD or SUD groups. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Prevalence of DSM-IV substance abuse and dependence disorders among prison inmates

The study examined the 30-day and lifetime prevalence of DSM-IV alcohol and drug disorders among state prison inmates. A sample of 400 inmates consecutively admitted to a state prison reception center were assessed for alcohol and drug disorders using the Structured Clinical Interview for DSM-IV (SCID-IV). Test-retest reliabilities were calculated for the SCID-IV. Lifetime substance abuse or dependence disorders were detected among 74% of inmates, including over half who were dependent on alcohol or drugs. For the 30 days prior to incarceration, over half of the sample were diagnosed as having substance abuse or dependence disorders, including 46% who were dependent on alcohol or drugs. Black inmates were significantly less likely to be diagnosed as alcohol dependent than whites or Hispanics. The high rates of substance use disorders are consistent with previous findings from other studies conducted in correctional settings and reflect the need to expand treatment capacity in prisons.     

Trajectories of change in adolescent substance use and symptomatology: Impact of paternal and maternal substance use disorders.

The effects of paternal and maternal substance use disorders (SUDs) on trajectories of change in adolescent offspring nicotine, alcohol, and drug use and symptomatology were investigated in a population-based sample of adolescent twins (N = 1,514). Adolescent and parental substance phenotypes were assessed when most adolescents were 11 years old, with 2 assessments of adolescents approximately every 3 years thereafter. Growth curves were fit using hierarchical linear modeling. Results indicated acceleration of substance involvement during adolescence, particularly for boys. Paternal and maternal SUD were each associated with more extreme trajectories. There was evidence for an additive, rather than interactive, combined parental effect. Findings help clarify the impact of paternal and maternal SUD on the development of substance involvement during adolescence. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Trauma exposure and posttraumatic stress disorder in psychosis: Findings from a first-admission cohort.

This study examined the lifetime prevalence of trauma exposure and posttraumatic stress disorder (PTSD) and their demographic, diagnostic, and trauma-related correlates in a clinical cohort of 426 patients with a first psychiatric admission for psychosis. The prevalence of trauma exposure was 68.5%. Female gender and substance abuse were risk factors for trauma exposure. The prevalence of PTSD was 14.3% in the full sample and 26.5% in those with trauma exposure. PTSD was less prevalent in patients with bipolar disorder and schizophrenia and was twice as common in women. Other significant risk factors were younger age and trauma exposure that was repeated and ongoing or that involved childhood victimization. The findings highlight the importance of systematically ascertaining trauma histories in patients with psychotic disorders. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Constructive thinking in adolescents with substance use disorders.

This study examined the concurrent validity and clinical correlates of the Constructive Thinking Inventory (CTI), a measure of experiential coping, in 551 adolescents aged 14–18 years with and without Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) substance use disorders (SUDs). The CTI was correlated with depression, anxiety, and conduct problems. After controlling for demographics and comorbid lifetime psychiatric disorders, the CTI scales of Behavioral Coping and Categorical Thinking distinguished adolescents with and without SUDs. Implications of these findings for assessment and treatment are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Occurrence and clinical correlates of psychiatric comorbidity in patients with psychotic disorders

BACKGROUND: The aim of this study was to explore patterns and clinical correlates of psychiatric comorbidity in patients with schizophrenia spectrum disorders and mood spectrum disorders with psychotic features. METHOD: Ninety-six consecutively hospitalized patients with current psychotic symptoms were recruited and included in this study. Index episode psychotic diagnosis and psychiatric comorbidity were assessed using the Structured Clinical Interview for DSM-III-R-Patient Version (SCID-P). Psychopathology was assessed by the SCID-P, Brief Psychiatric Rating Scale, Scale for the Assessment of Negative Symptoms, and Hopkins Symptom Checklist. Awareness of illness was assessed with the Scale to Assess Unawareness of Mental Disorders. RESULTS: The total lifetime prevalence of psychiatric comorbidity in the entire cohort was 57.3% (58.1% in schizophrenia spectrum disorders and 56.9% in mood spectrum psychoses). Overall, panic disorder (24%), obsessive-compulsive disorder (24%), social phobia (17.7%), substance abuse (11.5%), alcohol abuse (10.4%), and simple phobia (7.3%) were the most frequent comorbidities. Within the group of mood spectrum disorders, negative symptoms were found to be more frequent among patients with psychiatric comorbidity than among those without comorbidity, while such a difference was not detected within the group of schizophrenia spectrum disorders. Social phobia, substance abuse disorder, and panic disorder comorbidity showed the greatest association with psychotic features. An association between earlier age at first hospitalization and comorbidity was found only in patients with unipolar psychotic depression. Patient self-reported psychopathology was more severe in schizophrenia spectrum patients with comorbidity than in those without, while such a difference was less pronounced in mood spectrum psychoses. CONCLUSION: These findings suggest that psychiatric comorbidity is a relevant phenomenon in psychoses and is likely to negatively affect the phenomenology of psychotic illness. Further studies in larger psychotic populations are needed to gain more insight into the clinical and therapeutic implications of psychiatric comorbidity in psychoses.     

Trajectories of PTSD and substance use disorders in a longitudinal study of personality disorders.

This study investigated the co-occurrence of posttraumatic stress disorder (PTSD) and substance use disorders (SUDs) in a sample (N = 668) recruited for personality disorders and followed longitudinally as part of the Collaborative Longitudinal Personality Disorders Study. The study both examined rates of co-occurring disorders at baseline and temporal relationships between PTSD and substance use disorders over 4 years. Subjects with a lifetime history of PTSD at baseline had significantly higher rates of SUDs (both alcohol and drug) than subjects without PTSD. Latent class growth analysis, a relatively novel approach used to analyze trajectories and identify homogeneous subgroups of participant on the basis of probabilities of PTSD and SUD over time, identified 6 classes, which were compared with respect to a set of functioning and personality variables. The most consistent differences were observed between the group that displayed low probabilities of both SUD and PTSD and the group that displayed high probabilities of both.

Prevalence of substance use disorders among veterans and comparable nonveterans from the National Survey on Drug Use and Health.

The Department of Veterans Affairs (VA) operates over 200 substance abuse treatment programs. Historically, planning for these services has not been informed by population-level prevalence data. Accordingly, the authors analyzed the National Survey on Drug Use and Health data from 2000 to 2003 to estimate substance use and substance use disorder prevalence among all veterans. The authors present the data in comparison to comparable nonveterans. Data show notable rates of substance use among veterans; 22.6% and 4.4% of veterans reported binge drinking and any illicit drug use in the past month, respectively. In addition, prevalence varied by geographic location. Monitoring substance use prevalence is needed to ensure the VA and other substance use providers can plan appropriate substance use disorder services for current and future enrollees, including veterans of the current military operations in Iraq and Afghanistan.

Long-term patterns of service use and cost among patients with both psychiatric and substance abuse disorders

OBJECTIVES: This is a longitudinal study designed to determine: (1) if patients dually diagnosed with psychiatric and substance abuse disorders incur higher health care costs than other psychiatric patients and (2) if higher costs can be attributed to particular subgroups of the dually diagnosed or types of care. METHODS: Two cohorts of veterans treated in Veterans Affairs mental health programs at the start of fiscal year 1991 were followed for 6 years: one cohort of inpatients (n = 9,813) and the other of outpatients (n = 58,001). Data were analyzed on utilization of all types of Veterans Affairs health care. Repeated measures analysis of variance was used to examine cost differentials between dually diagnosed patients and other patients. RESULTS: Dually diagnosed outpatients incurred consistently higher health care costs than other psychiatric outpatients, attributable to higher rates of inpatient psychiatric and substance abuse care; however, this difference decreased with time. Costs were substantially higher in the inpatient cohort overall, but there were no differences in cost between dually diagnosed and other patients. CONCLUSIONS: In an atmosphere of cost cutting and moves toward outpatient care, the dually diagnosed may lose access to needed mental health services. Possibilities of developing more intensive outpatient services for these patients should be explored.     

Measuring risks and outcomes in substance use disorders prevention research.

Assessment planning in substance use disorder prevention research entails the identification of measurement domains and the selection of corresponding instruments needed to fulfill specific project goals. The study design, developmental periods examined, feasibility constraints, and anticipated statistical analyses are important considerations in optimally designing the assessment protocol. As a conceptual framework to organize the domains considered here as examples, the multifactorial model of complex disorders with elaborations emphasized by the discipline of developmental psychopathology is applied. Risks reviewed include family history, childhood maltreatment, peer relationships, and psychopathology. The substance involvement dimensions germane as outcomes include substance type, consumption quantity and frequency, and substance-related problems. Comprehensive diachronic evaluation over critical developmental periods provides the technical foundation for etiology and intervention research.

Personality and substance use disorders: A prospective study.

The personality systems of Cloninger (as measured by the Tridimensional Personality Questionnaire [TPQ]) and Eysenck (as measured by the Eysenck Personality Questionnaire [EPQ]) both have been linked to substance use and abuse. The current study examined the predictive utility of both systems for substance use disorder (SUD) diagnoses, both cross-sectionally and prospectively. Participants (N?=?489 at baseline) completed the EPQ and TPQ and were assessed via structured diagnostic interview at baseline and 6 years later (N?=?457 at follow-up). Both the EPQ and TPQ scales demonstrated bivariate cross-sectional and prospective associations with SUDs. Within each system, those dimensions marking a broad impulsive sensation-seeking or behavioral disinhibition trait were the best predictors prospectively, although the 2 systems were differentially sensitive to specific diagnoses. These relations remained significant even with autoregressivity, other concurrent SUD diagnoses, and multiple personality dimensions statistically controlled.

Prevalence of personality disorders among patients with anxiety disorders

Outpatients with a principal diagnosis of an anxiety disorder (n = 347) were administered the Structured Clinical Interview for DSM-III-R/Axis II Disorders (SCID-II) during their intake evaluation. At least one personality disorder was found in 35% of these patients. Patients with social phobia (61%) and generalized anxiety disorder (49%) were most often diagnosed with a personality disorder. Patients with simple phobia were rarely diagnosed with a personality disorder (12%). The most commonly diagnosed personality disorders were from the "anxious/fearful" cluster (27% received at least one diagnosis from cluster C), most notably avoidant and obsessive-compulsive personality. Our findings suggest that personality disorders, in general, are less prevalent among anxious patients than among depressive patients.     

Mood-congruent vs. mood-incongruent psychotic symptoms in affective psychotic disorders

General dentists are frequently called upon to manage maxillofacial infections. Such infections are usually well localized in their initial stages but can spread to become severe and potentially life-threatening. This paper discusses the anatomical basis of the spread of these infections and techniques relevant to the rational management of these serious conditions.     

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)
