Abstract
Introduction Due to their similar behavioral presentation, it can sometimes be challenging to distinguish between a social anxiety disorder (SAD) and the social avoidance that is frequently described in autism spectrum disorder (ASD). Moreover, a growing body of evidences is reporting that a significant proportion of subjects with ASD also meet the requirements for SAD and, vice versa, subjects with SAD tend to exhibit a higher prevalence of autistic traits. Aim In this framework, the current study aims to evaluate prevalence and correlates of autistic traits in a sample of adult subjects diagnosed with SAD and healthy controls (HC), also evaluating which autism spectrum dimensions may statistically predict higher SAD symptoms. Methods 56 subjects with a clinical diagnosis of SAD and 56 gender and age matched HC were recruited from the Psychiatric Clinic of the University of Pisa. Subjects were assessed with the SCID-5, the Social Anxiety Spectrum - Short Version (SHY- SV) and the Adult Autism Subthreshold Spectrum (AdAS Spectrum). Results SAD group scored significantly higher in all AdAS Spectrum and SHY-SV domains and total score compared to the HC group with no significant gender difference. SHY-SV total and domain scores, were strongly and positively and strongly correlated with all AdAS Spectrum domains and total score. AdAS Spectrum total score and Childhood/Adolescence, Non-Verbal Communication, Empathy and Restricted interests and Rumination domain scores score were significant predictors of higher SHY-SV score. Conclusion Our results confirm the link between SAD and autistic traits also in adult population, describing not only high levels of autistic traits in SAD adults, but also significant correlations between many core features of the two disorders and a predictive role of autistic traits on higher SAD symptoms.

Blakey SM, Campbell SB, Simpson TL. Associations Between Lifetime Panic Attacks, Posttraumatic Stress Disorder, and Substance Use Disorders in a Nationally Representative Sample. J Dual Diagn 2022; 18:21-32.

Abstract
Objective: Rates of lifetime substance use disorder (SUD) are high among people with lifetime posttraumatic stress disorder (PTSD). Panic attacks are also prevalent among trauma survivors and people with SUD, yet studies on PTSD/SUD have rarely examined comorbid panic. This potentially creates additional barriers to effective treatment for people with PTSD/SUD, in that panic may be under-diagnosed among people with PTSD/SUD and consequently attenuate treatment outcome. Additionally, research on PTSD/SUD often combines people with alcohol use disorder (AUD) and people with drug use disorders (DUDs) into a single group despite evidence that these two PTSD/SUD subgroups differ along important sociodemographic and clinical variables. This study tested the hypothesis that among adults with lifetime PTSD, panic attacks would be associated with greater lifetime risk for both AUD and DUD. We also explored whether panic attacks were associated with specific DUDs that frequently co-occur with PTSD (cannabis, sedatives/tranquilizers, heroin/opioids, and cocaine). Methods: Data were drawn from the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III), a cross-sectional national study. Adults with lifetime PTSD (N = 2,230) were classified into one of three groups based on diagnostic interview data: adults with PTSD/AUD (i.e., met criteria for PTSD and AUD but not DUD; n = 656), adults with PTSD/DUD (i.e., met criteria for PTSD and DUD, regardless of AUD diagnostic status; n = 643), or adults with PTSD-only (i.e., met criteria for PTSD but not AUD or DUD; n = 1,031). Results: Weighted logistic regression analyses showed that lifetime risk of PTSD/AUD and PTSD/DUD, each relative to PTSD-only, was greater for adults who were younger at the time of data collection, were male, and had a history of panic attacks. Panic attacks did not predict specific DUD diagnoses comorbid with PTSD in exploratory analyses adjusting for sociodemographic and clinical covariates. Conclusions: Findings highlight the importance of assessing and targeting panic in PTSD/SUD clinics, but suggest panic may not discriminate between specific DUDs that commonly co-occur with PTSD. Study limitations and future directions are discussed.

Abstract
BACKGROUND Sex differences in the development of alcohol dependence (AD) among patients with panic disorder (PD) remain unexplored. The study investigated sex as an effect modifier in the incidence of AD among patients with PD. METHOD We included 9480 patients with PD from the Taiwan National Health Insurance Research Database. A total of 169 patients (89 men and 80 women) developed incident AD during the follow-up period. Standardized incidence ratios (SIRs) were used to represent the relative risks of incident AD compared with the general population. Based on a nested case-control study design, 10 controls were selected for each case. Medical utilization and psychiatric comorbidity before diagnosing AD were analyzed using conditional logistic regression. RESULTS The SIR of incident AD was 3.36 for men and 6.29 for women. Women with PD and incident AD had more visits to the outpatient department than the controls did, whereas men exhibited no significant differences. Women with incident AD were more likely to comorbid with depressive disorder (adjusted risk ratio [aRR] = 2.94), personality disorder (aRR = 5.03), and sleep disorder (aRR = 1.72), whereas men with incident AD were more likely to comorbid with sleep disorder (aRR = 1.85) and other substance use disorders (aRR = 3.08). CONCLUSION Patients with PD have an additional risk of developing AD compared with the general population, and that risk is higher in women. Women and men exhibited dissimilar patterns of medical utilization and psychiatric comorbidity before developing AD. Sex differences should be taken into consideration when establishing preventive measures.

Abstract
BACKGROUND While few previous studies highlighted a higher prevalence of autistic traits among adults with Bipolar Disorder (BD), little is known about their clinical significance in this population. METHOD 143 subjects with BD were enrolled at the adult psychiatric inpatient clinic of the University of Pisa. Assessments included the SCID-5, the MOODS-SR, the AQ and the AdAS Spectrum. RESULTS 42.7% of the sample scored positively for significant levels of autistic traits. Subjects with high autistic traits showed a greater likelihood of a very early onset of BD, greater length of current in-hospital stay, significantly higher rates of anxiety disorders and lower rates of substance use disorders compared to patients with low autistic traits. They also show significantly greater depressive symptoms and suicidality across the lifetime. Suicidality was associated with the altered responsiveness to sensory input and inversely related to adherence to routine and inflexibility. CONCLUSION The study is a first exploration of the clinical significance of autistic traits among BD patients. Our results highlight the clinical significance of autistic traits in patients with BD, supporting the usefulness of a dimensional approach to the autism spectrum.

Abstract
In the framework of increasing attention towards autism-related conditions, a growing number of studies have recently investigated the prevalence and features of sub-threshold Autistic Traits (ATs) among adults. ATs span across the general population, being more pronounced in several clinical groups of patients affected by psychiatric disorders. Moreover, ATs seem to be associated with specific personality features in non-clinical population, implying both a higher vulnerability towards psychopathology and extraordinary talents in specific fields. In this framework, the DSM-5’s Autism Spectrum Disorder (ASD) presentations may be considered as the tip of an iceberg that features several possible clinical and non-clinical phenotypes. Globally, the autism spectrum may be considered as a trans-nosographic dimension, which may not only represent the starting point for the development of different psychopathological trajectories but also underlie non-psychopathological personality traits. These different trajectories might be shaped by the specific localization and severity of the neurodevelopmental alteration and by its interaction with the environment and lifetime events. In this wider framework, autistic-like neurodevelopmental alterations may be considered as a general vulnerability factor for different kinds of psychiatric disorders, but also the neurobiological basis for the development of extraordinary abilities, eventually underlying the concept of geniality. Moreover, according to recent literature, we hypothesize that ATs may also be involved in the functioning of human mind, featuring the peculiar sense of “otherness” which can be found, with different grades of intensity, in every human being.

Mood symptoms and suicidality across the autism spectrum. Compr Psychiatry 2019; 91:34-38.

Abstract
BACKGROUND Autism spectrum is a psychopathological dimension which encompasses a wide range of clinical presentations: from subthreshold forms and autistic traits (AT), that can be found in the general population, to full-blown autism spectrum disorder (ASD). Many studies reported high rates of comorbidity between both ASD and AT and mood disorders, as well as a high prevalence of suicidal ideation among patients with ASD/AT. The aim of this study was to investigate the presence of mood symptoms and suicidal ideation and behaviors in patients with full-blown ASD and in subjects with AT, as well in a healthy control (HC) group, with a specific focus on which of the autistic features may be predictive of suicidal ideation and behaviors. METHODS We recruited 262 adult subjects: 34 with ASD without intellectual impairment or language disability (ASD group), 68 fulfilling only one symptom criterion for ASD according to DSM-5 but who do not meet criteria for a full-blown diagnosis of ASD (AT group), and 160 HC. All subjects were assessed with the Structured Clinical Interview for DSM-5 (SCID-5); in addition, they were asked to fill two questionnaires: The Mood Spectrum, Self-report (MOODS-SR) and the Adult Autism Subthreshold Spectrum (AdAS Spectrum). RESULTS ASD subjects reported significantly higher AdAS Spectrum and MOODS-SR total scores, as well as higher MOODS-SR depressive component total scores, when compared with AT and HC subjects. AT subjects scored significantly higher than the HC group. No significant differences were reported between ASD and AT subjects for the suicidality score according to MOODS-SR, despite both groups scored significantly higher than the HC group. The strongest predictor of suicidality score were MOODS-SR depressive component score and AdAS Spectrum Restricted interests and rumination domain score. CONCLUSIONS Our results highlight a correlation between autism and mood spectrum, as well as between suicidality and both ASD and AT. Subthreshold forms of ASD should be accurately investigated due to their relationship with suicidal thoughts and behaviors.

Abstract
BACKGROUND While growing literature is stressing the link between Autistic Traits (AT) and trauma-/stress-related disorders, in both conditions significant differences have been separately reported. OBJECTIVE This study aims to evaluate the relationship between AT and trauma-/stress-related symptoms with respect to sex. METHODS 178 university students were assessed with the Structured Clinical Interview for DSM-5, the Trauma and Loss Spectrum (TALS) and the Adult Autism Subthreshold Spectrum (AdAS). In order to evaluate sex differences in trauma-/stress-related symptoms among subjects with higher or lower AT, the sample was split in two groups with an equal number of subjects on the basis of the median score reported on AdAS Spectrum ("AdAS high scorers" and "AdAS low scorers"). RESULTS Females reported significantly higher TALS total score, Loss events and Grief reaction domain scores than males in the whole sample, while AdAS high scorers reported significantly higher TALS total and domain scores than AdAS low scorers. A significant interaction between high/low AdAS score and sex emerged for TALS domains, with females scoring significantly higher than males only among AdAS low scorers, specifically on Loss events, Grief reaction, Re-experiencing and Personal characteristics/Risk factors domains. Finally, among AdAS high scorers a significantly higher rate of subjects fulfilled symptomatological criteria for PTSD than among AdAS low scorers, without sex differences. CONCLUSION Our results confirm a significant relationship between AT and trauma-/stress-related symptoms, which seems to prevail on sex differences among high-risk subjects.

Abstract
BACKGROUND Comorbidity between substance use disorders (SUDs) and bipolar disorder (BD) is highly prevalent to the extent it may almost be regarded the norm. This systematic review and meta-analysis aimed to estimate the prevalence rates of SUDs in treatment seeking patients diagnosed with BD in both inpatient and outpatient settings. METHODS A comprehensive literature search of Medline, EMBASE, psychINFO and CINAHL databases was conducted from 1990 to 2015. Prevalence of co-morbid SUDs and BD were extracted and odds ratios (ORs) were calculated using random effects meta-analysis. RESULTS There were 151 articles identified by electronic searches that yielded 22 large, multi-site studies and 56 individual studies describing comorbid rates of SUDs amongst community dwelling, BD inpatients or outpatients. The SUDs with the highest prevalence in BD were alcohol use (42%) followed by cannabis use (20%) and other illicit drug use (17%). Meta-analysis showed males had higher lifetime risks of SUDs compared to females. BD and comorbid SUDS were associated with earlier age of onset and slightly more hospitalisations than non-users. LIMITATIONS The results do not take into account the possibility that individuals may have more than one comorbid disorder, such as having more than one SUD, anxiety disorder, or other combination. Some of the meta-analyses were based on relatively few studies with high rates of heterogeneity. Most included studies were cross-sectional and therefore causality cannot be inferred. CONCLUSIONS This systematic review shows comorbidity between SUDs and bipolar illness is highly prevalent in hospital and community-based samples. The prevalence of SUDs was similar in patients with bipolar I and bipolar II disorders. This study adds to the literature demonstrating that SUDs are common in BD and reinforces the need to provide better interventions and properly conducted treatment trials to reduce the burden conferred by comorbid SUD and BD.

Abstract
In spite of the increasing number of studies on insight in psychiatry and also in neurology and psychology, its nature is still elusive. It encompasses at least three fundamental characteristics: the awareness of suffering from an illness, an understanding of the cause and source of this suffering, and an acknowledgment of the need for treatment. As such, insight is fundamental for patients' management, prognosis, and treatment. Not surprisingly, the majority of available data, which have been gathered on schizophrenia, show a relationship between low insight and poorer outcomes. For mood disorders, however, insight is associated with less positive results. For other psychiatric disorders, insight has rarely been investigated. In neurology, the impaired ability to recognize the presence of sensory, perceptual, motor, affective, or cognitive functioning-referred to as anosognosia-has been related to damage of specific brain regions. This article provides a comprehensive review of insight in different psychiatric and neurological disorders, with a special focus on brain areas and neurotransmitters that serve as the substrate for this complex phenomenon.

Abstract
The literature on symptoms of obsessive-compulsive disorder (OCD) in alcoholic patients is scarce and such symptoms can go unnoticed, worsening the prognosis of alcoholism. The objectives were to estimate the prevalence and severity of obsessive-compulsive symptoms in alcoholics undergoing outpatient treatment and to assess sociodemographic and clinical correlates, including suicidal behaviors. The instruments used in this cross-sectional study were the Obsessive-Compulsive Inventory - Revised (OCI-R), the Short Alcohol Dependence Data and the Beck Depression Inventory. After descriptive analyses, bivariate analyses between the categorical ("probable OCD": OCI-R≥27) and dimensional (OCI-R total and subscales scores) outcomes and all explanatory variables were conducted. Eleven (20.4%) of the 54 alcoholic patients (37 men and 17 women) presented "probable OCD", which was associated with lower income, more severe dependence, depression, lifetime suicidal thoughts and plans and suicide attempts. OCI-R severity (mean 16.0) was associated with the same predictors and with psychiatric hospitalization. Suicidal behaviors were mainly associated with the Obsession, Hoarding and Washing subscales. It is essential to investigate and treat OCD symptoms in alcoholics, as they are associated with greater severity of dependence, depression and suicidal behaviors. Longitudinal studies are required to assess the impact of OCD treatment on the clinical course of alcoholism.

Abstract
Although addictive syndromes have been traditionally related to substance-use disorders, during the last few decades a novel addictive group, including the so-called "behavioral or no-drug addictions," has been recognized and has attracted increasing attention for its relevant social impact. This group includes pathological gambling, compulsive shopping, TV/Internet/social network/videogame addictions, workaholism, sex and relationship addictions, orthorexia, and overtraining syndrome. Substance and behavioral addictions show similar phenomenological features, such as craving, dependence, tolerance, and abstinence, and perhaps they share a common possible pathophysiology. It is, however, controversial whether all or at least some of them should be considered real disorders or just normal, albeit extreme, behaviors. The aim of this article is to review current data on pharmacological treatment of behavioral addictions. As no specific and validated treatment algorithms are currently available, only an improved knowledge on their psychopathological, clinical, and neurobiological features may have relevant implications for more focused preventive and therapeutic strategies.

Abstract
BACKGROUND Post-traumatic Stress Disorder (PTSD) has demonstrated gender-specific prevalence and expressions across the different DSM definitions, since its first introduction in DSM-III. The DSM-5 recently introduced important revisions to PTSD symptomatological criteria. Aim of the present study is to explore whether gender moderates rates of DSM-5 PTSD expression in a non-clinical sample of survivors to a massive earthquake in Italy. METHODS 512 survivors of the L'Aquila 2009 earthquake, previously investigated for the presence DSM-IV-TR PTSD, were reassessed according to DSM-5 criteria in order to explore gender differences. All subjects completed the Trauma and Loss Spectrum-Self Report (TALS-SR). RESULTS Females showed significantly higher DSM-5 PTSD rates and rates of endorsement of almost all DSM-5 PTSD criteria. Significant gender differences emerged in almost half of PTSD symptomatological criteria with women reporting higher rates in 8 of them, while men in only one (a new symptom in DSM-5: reckless or self-destructive behavior). Considering the impact of the three new DSM-5 symptoms on the diagnosis, significant gender differences emerged with these being crucial in almost half of the PTSD diagnoses in males but in about one-fourth in females. By using ROC curves, DSM-5 criteria E and D showed the highest AUC values in males (.876) and females (.837), respectively. LIMITATIONS The use of self-report instrument; no information on comorbidity; homogeneity of study sample; lack of assessment on functional impairment. CONCLUSIONS This study provides a contribution to the ongoing need for reassessment on how gender moderates rates of expression of particular disorders such as PTSD.

[PMID: 25670961 PMCID: PMC4322820 DOI: 10.1186/s12991-014-0028-9] [Citation(s) in RCA: 32] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2014] [Accepted: 09/28/2014] [Indexed: 12/20/2022] Open
Abstract
BACKGROUND Gender differences in post-traumatic stress disorder (PTSD) rates were confirmed across different DSM editions as well as the role of bipolar disorder (BD) comorbidity on prevalence and course, but little data is available upon new DSM-5 criteria, including maladaptive behaviors. The aim of this study was to investigate gender differences in DSM-5 PTSD in a sample of young adult earthquake survivors and the impact of lifetime mood spectrum comorbidity. METHODS Five hundred twelve young adult survivors from the L'Aquila 2009 earthquake were evaluated by Trauma and Loss Spectrum-Self Report (TALS-SR) and Mood Spectrum-Self Report (MOODS-SR). RESULTS Females showed significantly higher DSM-5 PTSD prevalence rates than men. Similarly, female survivors with DSM-5 PTSD showed significantly higher scores in several of the MOODS-SR and TALS-SR domains with respect to males. Males showed significantly higher scores in the TALS-SR maladaptive coping domain only. A significant positive association between the MOODS-SR manic-hypomanic component and TALS-SR potentially traumatic events and maladaptive coping domains emerged in the whole sample, particularly among men. CONCLUSION This study allows a first glimpse on gender differences in DSM-5 PTSD criteria in a sample of earthquake survivors. Further, possible correlations with subthreshold manic-hypomanic comorbidity are suggested among males, showing a significant trend particularly for lifetime trauma exposure and for the newly introduced maladaptive behaviors.

Abstract
Obsessive-compulsive disorder (OCD) and substance use disorder share several aspects of phenomenology and may be underpinned by a common mechanism with compulsivity at the core. Despite this overlap, the two disorders show a variable pattern of comorbidity. Here, we review the current evidence for comorbidity across clinical and epidemiological studies, and propose a new heuristic for substance use comorbidity in OCD, based on a hypothetical threshold of OCD severity.

Abstract
Converging evidence from epidemiologic and treatment studies indicate that anxiety disorders and substance use disorders commonly co-occur, and the interaction is multifaceted and variable. Epidemiological studies and investigations within clinical substance abuse populations have found an association between anxiety disorders and substance use disorders. Specific anxiety disorders including generalized anxiety disorder, panic disorder, and post traumatic stress disorder have all been associated with substance use. The association with obsessive-compulsive disorder is less robust, and some research has found a negative association. The risk of nicotine dependence is significantly higher among individuals with an anxiety disorder, and conversely, smoking has been found to be associated with trait anxiety and anxiety disorders. A review of the current literature and the relationship between specific anxiety disorders and alcohol and substance use disorders is discussed in detail. This article, written for social workers in a variety of practice settings, reviews the prevalence, diagnostic, and treatment issues at the interface of substance use disorders and anxiety disorders.

Abstract
Despite the large amount of research conducted in this area over the last two decades, comorbidity of psychiatric
disorders remains a topic of major practical and theoretical significance. Official diagnostic and therapeutic guidelines of psychiatric disorders still do not provide clinicians and researchers with
any treatment-specific indications for those cases presenting with psychiatric comorbidity. We will discuss the diagnostic
improvement brought about, in clinical practice, by the punctual and refined recognition of threshold and subthreshold
comorbidity. From such a perspective, diagnostic procedures and forthcoming systems of classification of mental disorders
should attempt to combine descriptive, categorical and dimensional approaches, addressing more attention to the
cross-sectional and longitudinal analysis of nuclear, subclinical, and atypical symptoms that may represent a pattern of either
full-blown or partially expressed psychiatric comorbidity. This should certainly be regarded as a positive development.
Parallel, continuous critical challenge seems to be vital in this area, in order to prevent dangerous trivializations and
misunderstandings.

Abstract
OBJECTIVE To examine whether self-medication with drugs confers risk of comorbid mood and drug use disorders. METHOD A longitudinal, nationally representative survey was conducted by the National Institute on Alcohol Abuse and Alcoholism. The National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) assessed DSM-IV-TR psychiatric disorders, self-medication, and sociodemographic variables at 2 time points. A total of 34,653 adult, US participants completed both waves of the survey. Wave 1 was conducted between 2001 and 2002, and Wave 2 interviews took place 3 years later (2004-2005). Logistic regression and population attributable fractions were calculated to obtain estimates of the association between self-medication and incident disorders. RESULTS Logistic regression analyses revealed that self-medication with drugs conferred a heightened risk of new-onset drug dependence among those with baseline mood disorders (adjusted odds ratio [AOR] = 7.65; 95% CI, 3.70-15.82; P < .001) and accounted for over 25% of incident drug dependence disorders among people with mood disorders. Among those with comorbid mood and drug use disorders at baseline, self-medication with drugs was associated with the persistence of drug abuse (AOR = 2.47; 95% CI, 1.34-4.56; P < .01), accounting for over one-fifth of the persistence of drug use disorders at 3-year follow-up. CONCLUSIONS Self-medication with drugs among individuals with mood disorders confers substantial risk of developing incident drug dependence and is associated with the persistence of comorbid mood and drug use disorders. These results clarify a pathway that may lead to the development of mood and drug use disorder comorbidity and indicate an at-risk population, with potential points of intervention for prevention of comorbidity.

Abstract
BACKGROUND Medication-overuse headache (MOH) refers to headache attributed to excessive use of acute medications. The role of personality needs studies to explain the shifting from drug use to drug abuse. The main aim of this study is to study personality, according to Minnesota Multiphasic Personality Inventory, comparing MOH, episodic headache, substance addicts (SA) vs healthy controls. METHODS Eighty-two MOH patients (mean age 44.5; 20 M, 62 F) and 35 episodic headache (mean age 40.2; 8 M, 27 F), were compared to 37 SA (mean age 32.5; 29 M, 8 F) and 37 healthy controls (mean age: 32.49; 20 M, 17 F). International Classification of Headache Disorders 2nd Edition criteria were employed. Chi-square test, Kruskal-Wallis test, and post hoc comparisons were used for statistics. RESULTS MOH patients scored higher on Hypochondriasis, Depression (only females), Hysteria (only females) (P < .000). MOH did not show higher scores than episodic headache or healthy controls in dependency scales, while SA did. CONCLUSION The data obtained show that MOH and SA do not share common personality characteristics linked to dependence. Although further studies are needed to understand if such a difference is related to instrumental characteristics or to yet undiscovered psychobiological characteristics of MOH patients; however, we hypothesize that the detected difference may rely on the fact that drug dependence in the 2 groups is promoted by entirely different needs: pleasure seeking in the SA group, pain avoidance in the MOH group.

Abstract
BACKGROUND Post-traumatic stress disorder (PTSD) represents one of the most frequently psychiatric sequelae to earthquake exposure. Increasing evidence suggests the onset of maladaptive behaviors among veterans and adolescents with PTSD, with specific gender differences emerging in the latter. Aims of the present study were to investigate the relationships between maladaptive behaviors and PTSD in earthquake survivors, besides the gender differences in the type and prevalence of maladaptive behaviors and their association with PTSD. METHODS 900 residents of the town of L'Aquila who experienced the earthquake of April 6th 2009 (Richter Magnitude 6.3) were assessed by means of the Trauma and Loss Spectrum-Self Report (TALS-SR). RESULTS Significantly higher maladaptive behavior prevalence rates were found among subjects with PTSD. A statistically significant association was found between male gender and the presence of at least one maladaptive behavior among PTSD survivors. Further, among survivors with PTSD significant correlations emerged between maladaptive coping and symptoms of re-experiencing, avoidance and numbing, and arousal in women, while only between maladaptive coping and avoidance and numbing in men. CONCLUSIONS Our results show high rates of maladaptive behaviors among earthquake survivors with PTSD suggesting a greater severity among men. Interestingly, post-traumatic stress symptomatology appears to be a better correlate of these behaviors among women than among men, suggesting the need for further studies based on a gender approach.

Abstract
BACKGROUND The optimal treatment of patients with substance use disorders (SUDs) requires an awareness of their comorbid mental disorders and vice versa. The prevalence of comorbidity in first-time-admitted SUD patients has been insufficiently studied. Diagnosing comorbidity in substance users is complicated by symptom overlap, symptom fluctuations, and the limitations of the assessment methods. The aim of this study was to diagnose all mental disorders in substance users living in a single catchment area, without any history of treatment for addiction or psychiatric disorders, admitted consecutively to the specialist health services. The prevalence of substance-induced versus substance-independent disorders according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), in SUD patients will be described. METHODS First-time consecutively admitted patients from a single catchment area, aged 16 years or older, admitted to addiction clinics or departments of psychiatry as outpatients or inpatients will be screened for substance-related problems using the Alcohol Use Disorder Identification Test and the Drug Use Disorder Identification Test. All patients with scores above the cutoff value will be asked to participate in the study. The patients included will be diagnosed for SUD and other axis I disorders by a psychiatrist using the Psychiatric Research Interview for Substance and Mental Disorders. This interview was designed for the diagnosis of primary and substance-induced disorders in substance users. Personality disorders will be assessed according to the Structured Clinical Interview for DSM-IV axis II disorders. The Symptom Checklist-90-Revised, the Inventory of Depressive Symptoms, the Montgomery Asberg Depression Rating Scale, the Young Mania Rating Scale, and the Angst Hypomania Check List will be used for additional diagnostic assessments. The sociodemographic data will be recorded with the Stanley Foundation's Network Entry Questionnaire. Biochemical assessments will reveal somatic diseases that may contribute to the patient's symptoms. DISCUSSION This study is unique because the material represents a complete sample of first-time-admitted treatment seekers with SUD from a single catchment area. Earlier studies have not focused on first-time-admitted patients, so chronically ill patients, may have been overrepresented in those samples. This study will contribute new knowledge about mental disorders in first-time-admitted SUD patients.

Abstract
Previous studies have shown that both bipolar disorder (BPD) and psychomotor agitation (PMA) are associated with substance dependence. These two findings have yet to be integrated, despite evidence that PMA is closely linked with the bipolar spectrum. Accordingly, the current study examined whether BPD and PMA had unique or overlapping associations with substance dependence disorders. Participants were 2,300 individuals seeking outpatient psychiatric treatment. Before treatment, participants were assessed using structured clinical interviews, which yielded DSM-IV psychiatric diagnoses and clinical ratings of mood symptoms. Current PMA and lifetime BPD were present in 483 and 172 (bipolar I, n = 71; bipolar II, n = 101) participants, respectively. Current PMA and lifetime BPD each were associated with increased prevalence of lifetime nicotine, alcohol, and drug dependence (ORs >or= 1.52, ps <or= .0004). These associations remained significant when controlling for demographic characteristics and comorbid psychiatric disorders, except the link between agitation and alcohol dependence, which was reduced to a trend (p = .058). Although BPD and PMA were associated with each other, these two factors demonstrated unique, nonoverlapping relationships to nicotine, alcohol, and drug dependence. Individuals with both PMA and BPD exhibited especially high rates of comorbid substance dependence. The present results replicate and extend previous findings documenting the relations of BPD and PMA to substance dependence. BPD and PMA may represent independent psychopathological correlates of substance dependence. Future research should explore the theoretical and clinical significance of these potentially distinct relations to substance dependence.

Abstract
BACKGROUND There is a strong association between bipolar disorder (BD) and substance use disorder (SUD). The clinical and functional correlates of SUD in BD are still unclear and little is known about the role of excessive substance use that does not meet SUD criteria. Thus, the aims of the current study were to investigate lifetime rates of illicit substance use in BD relative to the normal population and if there are differences in clinical and functional features between BD patients with and without excessive substance use. METHODS 125 consecutively recruited BD in- and outpatients from the Oslo University Hospitals and 327 persons randomly drawn from the population in Oslo, Norway participated. Clinical and functional variables were assessed. Excessive substance use was defined as DSM-IV SUD and/or excessive use according to predefined criteria. RESULTS The rate of lifetime illicit substance use was significantly higher among patients compared to the reference population (OR = 3.03, CI = 1.9-4.8, p < .001). Patients with excessive substance use (45% of total) had poorer educational level, occupational status, GAF-scores and medication compliance, with a trend towards higher suicidality rates, compared to patients without. There were no significant group differences in current symptom levels or disease course between groups. CONCLUSION The percentage of patients with BD that had tried illicit substances was significantly higher than in the normal population. BD patients with excessive substance use clearly had impaired functioning, but not a worse course of illness compared to patients without excessive substance use. An assessment of substance use beyond SUD criteria in BD is clinically relevant.

Abstract
BACKGROUND Anxiety reactions and panic attacks are the acute symptoms most frequently associated with cannabis use. Understanding the relationship between cannabis and anxiety may clarify the mechanism of action of cannabis and the pathophysiology of anxiety. Aims of the present study were to review the nature of the relationship between cannabis use and anxiety, as well as the possible clinical, diagnostic and causal implications. METHOD Systematic review of the Medline, PsycLIT and EMBASE literature. RESULTS Frequent cannabis users consistently have a high prevalence of anxiety disorders and patients with anxiety disorders have relatively high rates of cannabis use. However, it is unclear if cannabis use increases the risk of developing long-lasting anxiety disorders. Many hypotheses have been proposed in an attempt to explain these relationships, including neurobiological, environmental and social influences. CONCLUSIONS The precise relationship between cannabis use and anxiety has yet to be established. Research is needed to fully clarify the mechanisms of such the association.

Abstract
BACKGROUND Using alcohol or drugs to reduce emotional distress (self-medication) has been proposed as an explanation for the high comorbidity rates between anxiety and substance use disorders. Self-medication has been minimally studied in mood disorders despite equally high rates of alcohol and drug use. METHODS Data came from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a large (n=43,093, age 18 years and older) nationally representative survey of mental illness in community-dwelling adults. Prevalence rates of self-medication were determined for DSM-IV mood disorders: dysthymia, major depressive disorder, bipolar I disorder, and bipolar II disorder. Multiple logistic regression generated odds ratios for the association between each category of self-medication and anxiety and personality disorders. RESULTS Almost one-quarter of individuals with mood disorders (24.1%) used alcohol or drugs to relieve symptoms. The highest prevalence of self-medication was seen in bipolar I disorder (41.0%). Men were more than twice as likely as women to engage in self-medication (Adjusted Odds Ratio=2.18; 95% Confidence Interval 1.90-2.49). After controlling for the effects of substance use disorders, self-medication was associated with higher odds of comorbid anxiety and personality disorders when compared to individuals who did not self-medicate. LIMITATIONS Cross-sectional design. CONCLUSIONS The use of alcohol and drugs to relieve affective symptoms is common among individuals with mood disorders in the general population, yet is associated with substantial psychiatric comorbidity. These findings may help clinicians identify a subgroup of people with mood disorders who suffer from a higher mental illness burden.

Abstract
OBJECTIVE Several factors can influence the quality of life in patients with coronary artery disease (CAD). The goal of this research was to measure quality of life in opium-addicted patients with CAD in order to assess the effect of CAD risk factors on their quality of life. METHOD The WHOQOL-BREF questionnaire was completed through interviews with 275 patients who underwent isolated coronary artery bypass surgery in Tehran Heart Centre between May and September 2006. RESULTS No significant differences were found in the mean scores of the four domains of quality of life between the addicted and non-addicted patients. Furthermore, the evaluation of QOL in the groups with CAD risk factors showed that the mean QOL domains were statistically similar between opium addicted and non-opium addicted patients. In the addicted group, men had a higher psychological health score than women. A previous history of myocardial infarction reduced the psychological score in this group. Also, in the addicted patients with a history of diabetes mellitus, social functioning was better than that of the non-diabetics. CONCLUSIONS The different domains of quality of life in our opium-addicted and non-addicted patients with CAD were similar; and among all the major risk factors for coronary artery disease, only female gender and a previous history of myocardial infarction could influence quality of life in the opium-addicted patients.

Abstract
The aim of this article is to examine the onset and clinical correlates of substance use in patients with psychotic disorders. One hundred and eight inpatients and outpatients with DSM-IV psychotic disorders were evaluated with the SCI-SUBS, an instrument designed to explore the spectrum of substance use and its clinical correlates. Comparisons were made between subjects with (n=47) and without (n=61) a DSM-IV diagnosis of substance use disorder (SUD). In patients with an early onset of psychosis (<17 years), the onset of SUD was subsequent. Patients with SUD had higher substance sensitivity, higher sensation-seeking traits and were more likely to self-medicate than patients without SUD. The reasons for self-medication endorsed by patients with SUD included relieving depression, achieving or maintaining euphoria, improving self-confidence and social abilities. Our results, based on a cross-sectional study, suggest that early onset of psychosis, substance sensitivity and sensation-seeking traits represent vulnerability factors for SUD. The relationships between SUD and psychosis should be examined systematically and clarified in longitudinal studies.

Abstract
In this study, we examine whether adolescent emotional and behavior problems vary by history of early alcohol experiences. A national sample of 6974 alcohol-naïve and 4337 alcohol-experienced youths aged 15-18 years were identified within the 2004 National Survey of Illegal Drug Use among Adolescents in Taiwan. Four alcohol experience groups were created based on recency and frequency of alcohol use: (1) naïve; never drank alcohol, (2) trial use; first and only consumption of alcohol occurred more than 6 months preceding the assessment, (3) past use; alcohol used on more than one occasion but had not had a drink in the 6 months prior to the assessment, and (4) current use; consumed alcohol more than once and drank within the 6 months preceding the interview. A Chinese adaptation of the Youth Self-Report (YSR) assessed eight behavior syndromes: withdrawn, anxious/depressed, somatic complaints, social problems, thought problems, attention problems, rule-breaking behavior, and aggressive behavior. Multivariate response models (GLM/GEE) were used to examine the relationship of alcohol experiences with emotional and behavior problems. Alcohol-using youth were more likely to experience several specific emotional or behavioral syndromes than their alcohol-naïve counterparts. For example, youth with a history of alcohol use had an estimated 30-60% increase in the odds of experiencing items within the aggressive behavior syndrome as compared with alcohol-naïve youth. The type of early alcohol involvement in adolescence may exert differential effects on emotions and behaviors expressed across and within syndromes; these may warrant distinctions in informing etiological research and preventive efforts.

Abstract
This study investigated the extent to which occasional cannabis use moderated anxiety and depression outcomes in the Collaborative Care for Anxiety and Panic (CCAP) study, a combined cognitive-behavioral therapy (CBT) and pharmacotherapy randomized effectiveness trial. Participants were 232 adults from six university-based primary care outpatient clinics in three West Coast cities randomized to receive either the CCAP intervention or the usual care condition. Results showed significant (P<.01) evidence of an interaction between treatment group (CCAP vs. usual care) and cannabis use status (monthly vs. less than monthly) for depressive symptoms, but not for panic disorder or social phobia symptoms (all P>.05). Monthly cannabis users' depressive symptoms improved in the CCAP intervention just as much as those who used cannabis less than monthly, whereas monthly users receiving usual care had significantly more depressive symptoms than those using less than monthly. A combined CBT and medication treatment intervention may be a promising approach for the treatment of depression among occasional cannabis users.

Abstract
INTRODUCTION This study was undertaken to evaluate the prevalence rate of anxiety comorbidity in bipolar subjects with and without alcohol use disorders (AUD). METHODS Bipolar men and women who entered the Stanley Foundation Bipolar Network (SFBN) underwent a Structured Clinical Interview for DSM-IV (SCID-IV) and were divided into those subjects meeting current or lifetime criteria for an alcohol use disorder (AUD=213) vs. those subjects who did not (non-AUD=137). Lifetime rates of comorbid anxiety disorder were evaluated between groups. RESULTS Of 350 subjects, 163 (46.5%) met criteria for an anxiety disorder. Panic disorder and OCD were the most common anxiety disorders in the AUD and non-AUD groups. OCD and specific phobia were significantly less prevalent in BP I patients with AUD compared to those without. Bipolar women with AUD had a significantly higher rate of PTSD than those without. CONCLUSION These data highlight the added liability of anxiety comorbidity in BP disorder. Specifically, the greater amount of PTSD and lesser amount of OCD in bipolar women with alcohol comorbidity may have important diagnostic and treatment implications beyond dual diagnosis. Further study in comorbidity patterns is encouraged to not only better understand illness burden, but to maximize pattern-specific treatment outcomes.

Abstract
BACKGROUND The purpose of this study was to examine whether rural inhabitants were more likely than urban inhabitants to meet the criteria for comorbid mental health and substance abuse or dependence disorders. METHODS Data were from the National Comorbidity Survey, and included 5185 (532=rural; 4653=urban) persons age 14-54 years of age who were interviewed using the Composite International Diagnostic Interview (CIDI). Logistic regression that accounted for the complex survey data and weighting scheme was utilized. RESULTS Participants residing in rural areas were more likely to meet the DSM-III-R criteria for past month alcohol abuse or dependence if they also met the diagnostic criteria for past month major depressive disorder (MDD) or lifetime antisocial personality disorder (ASPD), adjusting for age, race, gender, education and income. Similarly, rural participants were more likely to meet the criteria for comorbid drug abuse or dependence in the past month if they met the diagnosis for either past month MDD, generalized anxiety disorder or lifetime ASPD, controlling for demographic characteristics. Rural residents with any current mental disorder also were less likely to seek treatment than their urban counterparts. LIMITATIONS Data were collected in 1991 and do not capture changes in prevalence of comorbidities. Also, the small number of rural residents sampled resulted in small cell sizes for some comorbidities. CONCLUSIONS Rural residents were significantly more likely to meet the criteria for substance disorders given they also met the criteria for a mental disorder, and those with any current mental disorder were less likely to seek treatment. Since the overall prevalence of these disorders does not differ between rural and urban inhabitants, findings suggest that rural persons may lack access to adequate treatment for their mental health disorders and subsequently may be self-medicating with alcohol and/or drugs.

Abstract
In studies made in the last decade, patients consulting doctors because of depression and anxiety have very often turned out to suffer from bipolar type II and similar conditions with alternating depression and hypomania/mania (the bipolar spectrum disorders - BP). Specifically, about every second patient seeking consultation because of depression has been shown to suffer from BP, mainly bipolar type II. BP is often concealed by other psychiatric conditions, e.g. recurrent depression, psychosis, anxiety, addiction, personality disorder, attention-deficit hyperactivity disorder and eating disorder. BP shows strong heredity. Relatives of patients with BP also have a high frequency of the psychiatric conditions just mentioned. Conversion ("switching") from recurrent unipolar depressions (recurrent UP) to BP is common in very long longitudinal studies (over decades). Mood-stabilizing medicines are recommended to a great extent in the treatment of BP, since anti-depressive medicines are often not effective and involve a substantial risk of inducing mood swings. Particularly in the long-term pharmacological treatment of depression in BP anti-depressive medicines may worsen the condition, e.g. inducing a symptom triad of dysphoria, irritability and insomnia: ACID (antidepressant-associated chronic irritable dysphoria).

Abstract
Medication overuse is relatively common in patients with frequent headache. To explore the prevalence of patients who meet the criteria for substance dependence in Diagnostic and Statistical Manual of Mental Disorders, Edition IV (DSM-IV), and to identify variables of substance dependence among patients with chronic daily headache, we recruited consecutive patients with chronic daily headache at a headache clinic from November 1999 to June 2004. Each patient completed a headache intake form, a dependence questionnaire modified from DSM-IV, and the Hospital Anxiety and Depression Scale (HADS). The presence of probable medication overuse headache (pMOH) was defined on the basis of the International Classification of Headache Disorders, 2nd edition, 2004. A total of 1,861 patients with chronic daily headache (1,369 women, 492 men; mean age, 49.6+/-15.4 years) were recruited. Almost half (895/1,861, 48%) met criteria of pMOH, and 606 of these patients (606/895, 68%) met three of five DSM-IV substance dependence criteria. In contrast, only 191 of 968 patients without pMOH (20%) met the DSM-IV criteria (OR=8.6, [7.0-10.6], chi-square test, P<0.001). Patients who fulfilled DSM-IV criteria of dependence had higher numbers of physician appointments in the past year. Multivariate logistic regression analyses revealed that migraine headache, frequent physician consultation, intensity of headache, and presence of a higher anxiety score were significant independent variables for substance dependence. Among patients with chronic daily headache, pMOH was associated with behaviors of substance dependence.
