Relationship between psychiatric disorders and sexually transmitted diseases in a nationally representative sample

Objective

Sexually transmitted diseases (STDs) are a significant public health concern. Numerous internalizing and externalizing psychiatric disorders have been found to be related to STD risk. However, to date, no studies have examined several psychiatric disorders simultaneously to account for STD risk. Given that psychiatric disorders often co-occur and can be explained by a limited number of latent dimensions of psychopathology, it is important to examine whether the relationship between STDs and psychiatric disorders is best explained by broad dimensions of psychopathology.

Methods

The current study examined the associations between a range of Axis I and II psychiatric disorders at baseline and rates of STDs at a three-year follow-up in a large, nationally representative sample of adults in the United States (n = 34,434). A confirmatory factor analysis (CFA) was conducted to fit three factors, two internalizing and one externalizing. Structural equation modeling (SEM) was used to assess the relationships between and among the factors and STD status and to test for mediation.

Results

In bivariate analyses, most Axis I and Axis II disorders were associated with STD diagnosis at Wave 2, whereas the results of the structural model showed that only the externalizing factor was significantly associated with STD diagnosis at Wave 2. Further, the externalizing factor mediated the relationship between one of the internalizing factors and STD diagnosis.

Conclusion

Findings suggest the unique contribution of externalizing psychopathology to STD risk and the importance of examining latent dimensions of disorders when understanding this relationship between psychiatric disorders and STDs.     

Predominant typologies of psychopathology in the United States: A latent class analysis

Background

Latent class analysis (LCA) offers a parsimonious way of classifying common typologies of psychiatric comorbidity. We used LCA to identify the nature and correlates of predominant typologies of Axis I and II disorders in a large and comprehensive population-based sample of U.S. adults.

Methods

We analyzed data from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (2004–2005; n = 34,653), a population-based sample of U.S. adults. We derived latent classes based on all assessed Axis I and II disorders and examined the relationship between the identified Axis I classes and lifetime psychiatric disorders and suicide attempts, and physical and mental health-related quality of life.

Results

A four-class solution was optimal in characterizing predominant typologies of both Axis I and II disorders. For Axis I disorders, these included low psychopathology (n = 28,935, 84.0%), internalizing (n = 3693, 9.9%), externalizing (n = 1426, 4.5%), and high psychopathology (n = 599, 1.6%) classes. For Axis II disorders, these included no/low personality disorders (n = 31,265, 90.9%), obsessive/paranoid (n = 1635, 4.6%), borderline/dysregulated (n = 1319, 3.4%), and highly comorbid (n = 434, 1.1%) classes. Compared to the low psychopathology class, all other Axis I classes had significantly increased odds of mental disorders, elevated Axis II classes, suicide attempts and poorer quality of life, with the high psychopathology class having the overall highest rates of these correlates, with the exception of substance use disorders. Compared to the low psychopathology class, the internalizing and externalizing classes had increased rates of mood and anxiety disorders, and substance use disorders, respectively.

Conclusion

Axis I and II psychopathology among U.S. adults may be best represented by four predominant typologies. Characterizing co-occurring patterns of psychopathology using person-based typologies represents a higher-order classification system that may be useful in clinical and research settings.     

Other- and self-directed forms of violence and their relationships to DSM-IV substance use and other psychiatric disorders in a national survey of adults

Objective

To examine associations between DSM-IV psychiatric disorders and other- and self-directed violence in the general population.

Methods

Data were obtained from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) Waves 1 & 2 (n = 34,653). Four violence categories were derived from a latent class analysis (LCA) of 5 other-directed and 4 self-directed violent behavior indicators. Multinomial logistic regression examined class associations for gender, race–ethnicity, age and DSM-IV substance use, mood, anxiety, and personality disorders.

Results

Approximately 16% of adults reported some form of violent behavior distributed as follows: other-directed only, 4.6%; self-directed only, 9.3%; combined self- and other-directed, 2.0%; and no violence, 84.1%. The majority of the DSM-IV disorders included in this study were significantly and independently related to each form of violence. Generally, other-directed violence was more strongly associated with any substance use disorders (81%) and any personality disorders (42%), while self-directed violence was more strongly associated with mood (41%) and anxiety disorders (57%). Compared with these two forms of violence, the smaller group with combined self- and other-directed violence was more strongly associated with any substance use disorders (88%), mood disorders (63%), and personality disorders (76%).

Conclusion

Findings from this study are consistent with recent conceptualizations of disorders as reflecting externalizing disorders and internalizing disorders. The identification of the small category with combined forms of violence further extends numerous clinical studies which established associations between self- and other-directed violent behaviors. The extent to which the combined violence category represents a meaningful and reliable category of violence requires further detailed studies.     

Childhood adversity and personality disorders: results from a nationally representative population-based study

Background

Although, a large population-based literature exists on the relationship between childhood adversity and Axis I mental disorders, research on the link between childhood adversity and Axis II personality disorders (PDs) relies mainly on clinical samples. The purpose of the current study was to examine the relationship between a range of childhood adversities and PDs in a nationally representative sample while adjusting for Axis I mental disorders.

Methods

Data were from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC; n = 34,653; data collection 2004-2005); a nationally representative sample of the United States population aged 20 years and older.

Results

The results indicated that many types of childhood adversity were highly prevalent among individuals with PDs in the general population and childhood adversity was most consistently associated with schizotypal, antisocial, borderline, and narcissistic PDs. The most robust childhood adversity findings were for child abuse and neglect with cluster A and cluster B PDs after adjusting for all other types of childhood adversity, mood disorders, anxiety disorders, substance use disorders, other PD clusters, and sociodemographic variables (Odd Ratios ranging from 1.22 to 1.63). In these models, mood disorders, anxiety disorders, and substance use disorders also remained significantly associated with PD clusters (Odds Ratios ranging from 1.26 to 2.38).

Conclusions

Further research is necessary to understand whether such exposure has a causal role in the association with PDs. In addition to preventing child maltreatment, it is important to determine ways to prevent impairment among those exposed to adversity, as this may reduce the development of PDs.     

Personality disorders associated with full and partial posttraumatic stress disorder in the U.S. population: results from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions

Background

While it is well known that personality disorders are associated with trauma exposure and PTSD, limited nationally representative data are available on DSM-IV personality disorders that co-occur with posttraumatic stress disorder (PTSD) and partial PTSD.

Methods

Face-to-face interviews were conducted with 34,653 adults participating in the Wave 2 National Epidemiologic Survey on Alcohol and Related Conditions. Logistic regression analyses controlling for sociodemographics and additional psychiatric comorbidity evaluated associations of PTSD and partial PTSD with personality disorders.

Results

Prevalence rates of lifetime PTSD and partial PTSD were 6.4% and 6.6%, respectively. After adjustment for sociodemographic characteristics and additional psychiatric comorbidity, respondents with full PTSD were more likely than trauma controls to meet criteria for schizotypal, narcissistic, and borderline personality disorders (ORs = 2.1-2.5); and respondents with partial PTSD were more likely than trauma controls to meet diagnostic criteria for borderline (OR = 2.0), schizotypal (OR = 1.8), and narcissistic (OR = 1.6) PDs. Women with PTSD were more likely than controls to have obsessive-compulsive PD. Women with partial PTSD were more likely than controls to have antisocial PD; and men with partial PTSD were less likely than women with partial PTSD to have avoidant PD.

Conclusions

PTSD and partial PTSD are associated with borderline, schizotypal, and narcissistic personality disorders. Modestly higher rates of obsessive-compulsive PD were observed among women with full PTSD, and of antisocial PD among women with partial PTSD.     

Axis I and Axis II diagnoses in women with PCOS

Objective

The objective was to determine the current prevalence of Axis I and Axis II psychiatric diagnoses in patients with polycystic ovary syndrome (PCOS).

Method

The study sample included 73 patients with PCOS and 73 control subjects. Psychiatric disorders were determined by structured clinical interviews.

Results

The rate of any Axis I psychiatric disorder (28.8% vs. 15.1%), social phobia (13.7% vs. 2.7%), generalized anxiety disorder (11.0% vs. 1.4%), any Axis II psychiatric disorder (23.3% vs. 9.6%) and avoidant personality disorder (12.3% vs. 1.4%) was significantly more common in the patient group compared to the control group.Of women with PCOS, 21 (28.8%) had at least one Axis I and 17 (23.3%) had at least one Axis II diagnosis. The most common Axis I disorder was social phobia (13.7%) and the most common Axis II disorder was avoidant personality disorder (12.3%) in women with PCOS. Social phobia, generalized anxiety disorder, and avoidant personality disorder were significantly more common in the patient group compared to the control group.

Conclusion

Our results suggest that a considerable proportion of women with PCOS also present with anxiety and personality disorders.     

Co-occurrence of Axis I and Axis II disorders in substance abusers

OBJECTIVE: This study examined the co-occurrence of anxiety/mood and personality disorders (PDs) in substance abusers, the impact of anxiety/ mood disorders on the symptom profiles of PDs, and the impact of anxiety/mood disorders and PDs on pre-treatment status. METHOD: Current anxiety/mood disorders and PDs and pre-treatment status were assessed using semi-structured interviews in 370 treated substance abusers. RESULTS: Anxiety/mood disorders and PDs frequently co-occurred, with the overall pattern of associations being non-specific. The strongest associations were of social phobia with avoidant and schizotypal PD, and of major depression with borderline PD. However, symptom profiles of PDs were not associated with anxiety/mood disorders. Finally, anxiety/mood disorders and PDs were both independently and differentially associated with poor pre-treatment characteristics. CONCLUSION: The findings suggest the clinical importance of obtaining both Axis I and Axis II diagnoses in treated substance abusers, and highlight the distinctiveness of the Axis I and Axis II disorders.     

Comorbid atypical depression in borderline personality disorder is common and correlated with anxiety-related psychopathology

Background

The core features of borderline personality disorder (BPD) are affective instability, unstable relationships and identity disturbance. Axis I comorbidities are frequent, in particular affective disorders. The concept of atypical depression is complex and often underestimated. The purpose of the study was to investigate the comorbidity of atypical depression in borderline patients regarding anxiety-related psychopathology and interpersonal problems.

Methods

Sixty patients with BPD were assessed with the Structured Clinical Interviews for DSM-IV Axis I and II Disorders (SCID I, SCID II) as well as the Atypical Depression Diagnostic Scale (ADDS). Additionally, patients completed a questionnaire (SCL-90-R, BDI, STAI, STAXI, IIP-C).

Results

Forty-five BPD patients (81.8%) had a comorbid affective disorder of which 15 (27.3%) were diagnosed with an atypical depression.In comparison to patients with major depressive disorder or no comorbid depression, patients with atypical depression showed significant higher scores in psychopathological symptoms regarding anxiety and global severity as well as interpersonal problems.

Conclusions

The presence of atypical depression in borderline patients is correlated with psychopathology, anxiety, and interpersonal problems and seems to be of clinical importance for personalized treatment decisions.     

Dimensions underlying psychotic and manic symptomatology: Extending normal-range personality traits to schizophrenia and bipolar spectra

Objective

Covariance among psychiatric disorders can be accounted for by higher-order internalizing, externalizing, and psychosis dimensions, but placement of bipolar disorder within this framework has been inconsistent. Moreover, whether deviations in normal-range personality can explain psychosis and vulnerability to severe mood lability, as seen in schizophrenia and bipolar disorder, remains unclear.

Methods

Exploratory factor analysis of interviewer-rated clinical symptoms in patients with schizophrenia or bipolar disorder, their first-degree biological relatives, and nonpsychiatric controls (total N = 193), followed by examination of associations between symptom dimensions and self reports on personality questionnaires.

Results

Covariance in symptoms was accounted for by five factors: positive symptoms of psychosis, negative symptoms of psychosis, disorganization, mania, and depression/anxiety. Schizophrenia and bipolar patients/relatives reported elevated negative emotionality and absorption and lower positive emotionality relative to controls. Personality did not differ between schizophrenia and bipolar patients/relatives, but there was a different pattern of associations between symptoms and personality in these groups.

Conclusions

Discrete dimensions reflecting psychotic, manic, and depressive symptoms emerge when a broad set of clinical symptoms is examined in a sample overrepresented by psychotic experiences and affective disturbances. Although normal-range personality traits index common phenotypes spanning schizophrenia and bipolar spectra, the same symptoms may carry different significance across disorders.     

Suicide attempts and clinical risk factors in patients with bipolar and unipolar affective disorders

Background

Suicide is an important clinical problem in psychiatric patients. The highest risk of suicide attempts is noted in affective disorders.

Objective

The aim of the study was to look for suicide risk factors among sociodemographic and clinical factors, family history and stressful life events in patients with diagnosis of unipolar and bipolar affective disorder (597 patients, 563 controls).

Method

In the study, the Structured Clinical Interview for DSM-IV Axis I Disorders and the Operational Criteria Diagnostic Checklist questionnaires, a questionnaire of family history, and a questionnaire of personality disorders and life events were used.

Results

In the bipolar and unipolar affective disorders sample, we observed an association between suicidal attempts and the following: family history of psychiatric disorders, affective disorders and psychoactive substance abuse/dependence; inappropriate guilt in depression; chronic insomnia and early onset of unipolar disorder. The risk of suicide attempt differs in separate age brackets (it is greater in patients under 45 years old). No difference in family history of suicide and suicide attempts; marital status; offspring; living with family; psychotic symptoms and irritability; and coexistence of personality disorder, anxiety disorder or substance abuse/dependence with affective disorder was observed in the groups of patients with and without suicide attempt in lifetime history.     

Co-occurrence of Axis I and Axis II disorders in female and male patients with panic disorder with agoraphobia

Objective

The aim of this study is to compare female and male patients with panic disorder with agoraphobia (PDA) for the co-occurring Axis I and Axis II (personality) disorders, to better understand sex differences in PDA.

Methods

The Structured Clinical Interview for Diagnostic and Statistical Manual for Mental Disorders, Fourth Edition (DSM-IV) Axis I Disorders, Clinician Version and the Structured Clinical Interview for DSM-IV Axis II Personality Disorders were administered to 157 consecutive outpatients (112 females and 45 males) with principal diagnosis of PDA, who sought treatment at the 2 anxiety disorders clinics. Women and men with PDA were then compared with regard to the type and frequency of the co-occurring Axis I and Axis II disorders.

Results

Women with PDA had a statistically greater tendency to receive co-occurring Axis I diagnoses and a greater number of Axis I diagnoses than men. Such a difference was not found for personality disorders. However, no sex difference was found for the mean number of co-occurring Axis I and Axis II diagnoses per patient. There were significantly more women with at least one co-occurring anxiety disorder. Women had a significantly higher frequency of specific phobia, whereas men were diagnosed with hypochondriasis and past alcohol abuse or dependence significantly more often. With regard to Axis II disorders, the only significant sex difference pertained to the higher frequency of dependent personality disorder among women.

Conclusions

The results of this study suggest that there are more similarities than differences between sexes in the co-occurring Axis I and Axis II disorders. Still, the relatively specific relationships between PDA and excessive alcohol use in men and between PDA and dependent personality traits and personality disorder in women seem important and have implications for clinical practice and treatment.     

The joint structure of normal and pathological personality: Further evidence for a dimensional model

Objective

The literature proposes a joint structure of normal and pathological personality with higher-order factors mainly based on the five-factor model of personality (FFM). The purpose of the present study was to examine the joint structure of the FFM and the DSM-IV personality disorders (PDs) and to discuss this structure with regard to higher-order domains commonly reported in the literature.

Methods

We applied a canonical correlation analysis, a series of principal component analyses with oblique Promax rotation and a bi-factor analysis with Geomin rotation on 511 subjects of the general population of Zurich, Switzerland, using data from the ZInEP Epidemiology Survey.

Results

The 5 FFM traits and the 10 DSM-IV PD dimensions shared 77% of total variance. Component extraction tests pointed towards a two- and three-component solution. The two-component solution comprised a first component with strong positive loadings on neuroticism and all 10 PD dimensions and a second component with strong negative loadings on extraversion and openness and positive loadings on schizoid and avoidant PDs. The three-component solution added a third component with strong positive loadings on conscientiousness and agreeableness and a negative loading on antisocial PD. The bi-factor model provided evidence for 1 general personality dysfunction factor related to neuroticism and 5 group factors, although the interpretability of the latter was limited.

Conclusions

Normal and pathological personality domains are not isomorphic or superposable, although they share a substantial proportion of variance. The two and three higher-order domains extracted in the present study correspond well to equivalent factor-solutions reported in the literature. Moreover, these superordinate factors can consistently be integrated within a hierarchical structure of alternative four- and five-factor models. The top of the hierarchy presumably constitutes a general personality dysfunction factor which is closely related to neuroticism.     

DSM-IV personality disorders in the National Comorbidity Survey Replication.

BACKGROUND: The population prevalence of DSM-IV personality disorders (PDs) remains largely unknown. Data are reported here on the prevalence and correlates of clinician-diagnosed Clusters A, B, and C DSM-IV PDs in the general population of the United States. METHODS: Personality disorder screening questions from the International Personality Disorder Examination (IPDE) were administered in Part II (n = 5692) of the National Comorbidity Survey Replication (NCS-R). A probability sub-sample was then interviewed with the IPDE and used to link screening question responses with IPDE clinical diagnoses. The method of Multiple Imputation (MI) was then implemented to estimate prevalence and correlates of PDs in the full sample. RESULTS: The MI prevalence estimates were 5.7% Cluster A, 1.5% Cluster B, 6.0% Cluster C, and 9.1% any PD. All three PD clusters were significantly comorbid with a wide range of DSM-IV Axis I disorders. Significant associations of PDs with functional impairment were largely accounted for by Axis I comorbidity. CONCLUSIONS: Strong Axis I comorbidity raises questions about the somewhat arbitrary separation of PDs from Axis I disorders in the DSM nomenclature. The impairment findings suggest that the main public health significance of PDs lies in their effects on Axis I disorders rather than in their effects on functioning.     

Utilisation du modèle de personnalité à cinq facteurs (FFM) dans l’évaluation des troubles de la personnalité du DSM-IV

Introduction

Widespread and long-standing dissatisfaction with the current DSM-IV diagnostic system for the personality disorders (PDs) revolves around five specific issues: use of a dichotomous, categorical model; extremely high rates of comorbidity within the PDs, as well as with Axis I disorders; excessive heterogeneity within the PDs; nonempirically derived diagnostic cut-offs and limited coverage of the personality pathology seen by clinicians. Many critics have suggested that the personality pathology might be better characterized using a dimensional trait model of general or pathological personality. Much research documents support relations between the PDs and the five-factor model of personality (FFM), a prominent model of general personality functioning. Recent research has examined the ability of FFM trait configurations to assess the DSM-IV PDs. Initial work focused on matching individual FFM profiles to prototypical PD profiles derived from expert ratings. Although this initial work showed that these FFM-assessed PDs performed like explicit PD assessments, the prototype matching approach was deemed cumbersome and a simpler, alternative count technique derived from the expert profiles was developed. The FFM PD counts sum the facets rated as being particularly prototypic (high or low) of a PD.

The current study

The current study tests the FFM PD counts by examining their convergent and discriminant validity correlations with explicit measures of DSM-IV PD symptomatology in two clinical samples (one French; one Belgian). In addition, “receiver operator characteristics” (ROC) analyses are used to provide information on the clinical utility of the FFM PD counts.

Method

The French clinical sample consisted of 100 female inpatients hospitalized for treatment of an eating disorder, whereas the Belgian clinical sample consisted of 130 psychiatric inpatients (47% women) with diverse presenting problems. Translated versions of the NEO PI-R were used to assess the FFM in each sample and to generate the FFM PD counts. DSM-IV PD symptom counts and diagnoses were obtained via structured interview in the French sample and via self-reports in the Belgian sample.

Results

In the French sample, convergent validity correlations between the FFM PD counts and DSM symptom counts ranged from 0.20 to 0.65 with a median r of 0.47. In the Belgian sample, these correlations ranged from 0.17 to 0.61 with a median r of 0.45. For the French sample, the median discriminant correlations for each FFM PD ranged from −0.23 to 0.35; for the Belgian sample they ranged from −0.13 to 0.28. Finally, ROC analyses were conducted for the PDs in which 10 or more individuals met the DSM diagnosis. ROC analyses provide “areas under the curve” (AUC), as well as other diagnostic efficiency statistics. An AUC of 0.50 indicates that the FFM PD count is no better at distinguishing between those with and without a given PD diagnosis than chance. AUCs were significant for all PDs examined except for the OCPD, ranging from 0.57 to 0.94 with a mean of 0.75. Average diagnostic efficiency statistics were also generally good.

Discussion

The FFM PD counts adequately assess the majority of extant DSM PDs. With the recent development of normative data and scoring sheets, these FFM counts can be applied in most clinical settings. Importantly, FFM data can be used flexibly with a focus either on the role of specific domains and facets or on specific trait configurations. Additionally, there are theoretical benefits to conceiving of PDs as constellations of FFM trait. Comorbidity is to be expected to the degree that the PDs include the same traits. The FFM PD counts are inherently dimensional, representing approximations to a prototype; thus, concerns surrounding the PDs as categories are rendered inert. Using the FFM to conceptualize the PDs allows basic research on personality to inform research on the etiology, course and treatment of the PDs.     

Personality traits,interpersonal problems and therapeutic alliance in early schizophrenia spectrum disorders

Background

The quality of the therapeutic alliance is associated with engagement in- and thus important to the outcome of- treatment in schizophrenia. In non-psychotic disorders, general personality traits and individual patterns of interpersonal problems have been linked to the formation and quality of the therapeutic alliance. The role of these factors in relation to therapeutic alliance has not previously been explored in schizophrenia spectrum disorders.

Aim

To investigate associations between personality traits, interpersonal problems and the quality of the therapeutic alliance in early schizophrenia spectrum disorders.

Methods

Demographic and clinical characteristics including Positive and Negative Syndrome Scale (PANSS) scores were assessed in 42 patients. Personality traits and interpersonal problems were assessed with the NEO Five factor Inventory (NEO-FFI) and the circumplex model of the Inventory of Interpersonal Problems (IIP-64C). Therapeutic alliance was measured with the Working Alliance Inventory – short form (WAI-S).

Results

Patient WAI-S scores were predicted by IIP-64C Submissive/Hostile interpersonal problems, age and PANSS excitative symptoms. Therapist WAI-S scores were predicted by NEO-FFI Agreeableness and the PANSS insight item.

Conclusion

Core traits of personality and dimensions of interpersonal problems are associated with both patients' and therapists' perceptions of the quality of the working alliance.     

Prevalence of personality disorders using two diagnostic systems in psychiatric outpatients in Shanghai, China: a comparison of uni-axial and multi-axial formulation

Objective

To compare multi-axial (DSM-IV) with uni-axial diagnostic system (CCMD-3, Chinese Classification and Diagnostic Criteria of Mental Disorders) as diagnostic methods to determine the prevalence of personality disorders (PDs) in Chinese psychiatric outpatients.

Method

3,075 outpatients were randomly sampled from clinical settings in China. CCMD-3 PDs were evaluated as per routine psychiatric practice. DSM-IV PDs were assessed using both self-reported questionnaire and structured clinical interview.

Results

The prevalence estimate for any type of PD in the total sample is 31.93% as reflected in the DSM-IV. This figure is nearly 110 times as large as the prevalence estimate for the CCMD-3. Only 9 outpatients were diagnosed with PD based on the CCMD-3. Amongst the 10 forms of DSM-IV PDs, avoidant (8.1%), obsessive–compulsive (7.6%), paranoid (6.0%), and borderline (5.8%) PDs were the most prevalent subtypes. This study found that PDs are commonly associated with the following: (i) the younger aged; (ii) single marital status; (iii) those who were not raised by their parents; (iv) introverted personalities; (v) first-time seekers of psycho-counseling treatment; and (vi) patients with co-morbid mood or anxiety disorders.

Conclusions

PDs are easily overlooked when the diagnosis is made based on the CCMD-3 uni-axial diagnostic system. However, it was found that personality pathology is common in the Chinese psychiatric community when using the DSM-IV classification system. Existing evidence suggest, at least indirectly, that there are important benefits of moving towards a multi-axial diagnostic approach in psychiatric practice.     

Pretreatment outcome indicators in an eating disorder outpatient group: The effects of self-esteem,personality disorders and dissociation

Objective

The prognosis for eating disorders (ED) is unsatisfactory, and the literature about outcome indicators is controversial. The present study evaluates the roles of self-esteem, personality disorders (PD), and dissociation as outcome predictors.

Method

Fifty-seven ED outpatients were recruited from a population beginning a Cognitive Behavioral Therapy-Enhanced (CBT-E) treatment. All patients received the Structured Clinical Interview for DSM-IV Axis I (SCID-I), the Structured Clinical Interview for DSM-IV Axis II (SCID-II), and completed the Eating Disorder Examination Questionnaire (EDE-Q), the Dissociation Questionnaire (DIS-Q), and the Rosenberg Self-Esteem Scale (RSES). One month after the end of treatment, recovery was evaluated as meeting the DSM-IV criteria for EDs.

Results

A small group of patients recovered (42.2%). Low self-esteem and dissociation results correlated with a negative outcome.

Discussion

Dissociation may be an important moderator of psychotherapy and treatment success, as already suggested by previous studies on non-eating-related disorders.     

Smoking and ADHD: an evaluation of self medication and behavioral disinhibition models based on comorbidity and personality patterns

Objective

The prevalence of smoking is significantly increased among adults with Attention-Deficit/Hyperactivity Disorder (ADHD), and this association has a significant impact in both disorders, ascribed to either self-medication or behavioral disinhibition hypotheses. However, little is known about clinical variables associated with cigarette smoking among patients with ADHD. The present study evaluates comorbidity, demographic and personality profiles of patients with ADHD in relation to smoking status.

Methods

Patients (n 422) were evaluated in the adult ADHD outpatient clinic of Hospital de Clínicas de Porto Alegre. Diagnoses were based on DSM-IV criteria and interviews were performed with Portuguese version of K-SADS-E for ADHD and Oppositional-Defiant Disorder. Axis I psychiatric comorbidities were evaluated with the SCID-I and smoking behavior with Fagerström Test for Nicotine Dependence (FTND). Personality was evaluated with Cloninger’s Temperament and Character Inventory (TCI). Results: The presence of smoking was strongly associated with externalizing characteristics as antisocial personality disorder (OR 4.2) and substance dependence (OR 6.5), but not with internalizing disorders. Moreover, smoking was associated with higher novelty seeking and lower harm avoidance scores.

Conclusions

Smoking initiation among patients with ADHD is consistent with a behavioral disinhibition profile beyond the possible role of self-medication in smoking persistence. Smoking in these patients is strongly associated with externalizing comorbid disorders.     

Associations between DSM-IV mental disorders and subsequent self-reported diagnosis of cancer

Objective

The associations between mental disorders and cancer remain unclear. It is also unknown whether any associations vary according to life stage or gender. This paper examines these research questions using data from the World Mental Health Survey Initiative.

Methods

The World Health Organization Composite International Diagnostic Interview retrospectively assessed the lifetime prevalence of 16 DSM-IV mental disorders in face-to-face household population surveys in nineteen countries (n = 52,095). Cancer was indicated by self-report of diagnosis. Smoking was assessed in questions about current and past tobacco use. Survival analyses estimated associations between first onset of mental disorders and subsequently reported cancer.

Results

After adjustment for comorbidity, panic disorder, specific phobia and alcohol abuse were associated with a subsequently self-reported diagnosis of cancer. There was an association between number of mental disorders and the likelihood of reporting a cancer diagnosis following the onset of the mental disorder.This suggests that the associations between mental disorders and cancer risk may be generalised, rather than specific to a particular disorder. Depression is more strongly associated with self-reported cancers diagnosed early in life and in women. PTSD is also associated with cancers diagnosed early in life.

Conclusion

This study reports the magnitude of the associations between mental disorders and a self-reported diagnosis of cancer and provides information about the relevance of comorbidity, gender and the impact at different stages of life. The findings point to a link between the two conditions and lend support to arguments for early identification and treatment of mental disorders.     

Gambling problem severity and psychiatric disorders among Hispanic and white adults: findings from a nationally representative sample

Objective

To examine differences in the associations of gambling problem severity and psychiatric disorders among a nationally representative sample of Hispanic and white adults.

Method

Chi-square tests and multinomial logistic regression analyses were performed on data obtained from the National Epidemiologic Survey on Alcohol and Related Conditions from 31,830 adult respondents (13% Hispanic; 87% white), who were categorized according to three levels of gambling problem severity (i.e., no gambling or low-frequency gambling [NG], low-risk or at-risk gambling [LRG], problem or pathological gambling [PPG]).

Results

Hispanic respondents in comparison to white respondents were more likely to exhibit PPG. Problem gambling severity was associated with past-year Axis I and lifetime Axis II psychiatric disorders in both Hispanic and white respondents, with the largest odds typically observed in association with the most severe gambling pathology. A stronger relationship between subsyndromal gambling and a broad range of Axis I disorders (mood, anxiety and substance use disorders) and Axis II disorders (particularly cluster B) was observed in Hispanic respondents as compared to white ones.

Conclusions

Levels of problem gambling severity are associated with the prevalence of Axis I and Axis II psychiatric disorders in both Hispanics and whites. Differences in the patterns of co-occurring disorders between subsyndromal levels of gambling in Hispanic and white respondents indicate the importance of considering ethnicity/race-related factors related to subthreshold levels of gambling in developing improved mental health prevention and treatment strategies.
