Little is known about whether severe psychopathology influences the assessment of self-reported attachment style. Fifty-eight randomly selected adult psychiatric inpatients completed the Experiences in Close Relationship questionnaire (ECR; Brennan, Clark, & Shaver, 1998) and were administered the 24-item Brief Psychiatric Rating Scale (BPRS; Ventura et al., 1993) and the Hamilton Depression Rating Scale (HDRS; Hamilton, 1960) at both admission and discharge. The Structured Clinical Interview for DSM-IV (SCID-I; First, Spitzer, Gibbon, & Williams, 1996) was used to establish Axis I diagnoses. The ECR scales showed good internal consistency and absolute stability both in patients with (n = 24) and without (n = 34) a psychotic disorder. Relative stability was only fair among patients with psychotic disorders but good among patients without psychotic disorders. Neither higher BPRS or HDRS scores, nor the presence of a psychotic disorder, significantly reduced the retest reliability of the ECR scales. These findings suggest that self-report measures might provide a reliable assessment of attachment style in patients with severe psychopathology, except for the most severely impaired patients.

Cocaine consumption can induce transient psychotic symptoms, expressed as paranoia or hallucinations. Cocaine induced psychosis (CIP) is common but not developed in all cases. This is the first European study on the relationship between CIP, consumption pattern variables and personality disorders. We evaluated 173 cocaine-dependent patients over 18 years; mostly males, whose average age was 33.6 years (SD=7.8). Patients attending an outpatient addictions department were enrolled in the study and subsequently systematically evaluated using SCID I and SCID II interviews for comorbid disorders, a clinical interview for psychotic symptoms and EuropASI for severity of addiction. A high proportion of cocaine dependent patients reported psychotic symptoms under the influence of cocaine (53.8%), the most frequently reported being paranoid beliefs and suspiciousness (43.9%). A logistic regression analysis was performed, finding that a model consisting of amount of cocaine consumption, presence of an antisocial personality disorder and cannabis dependence history had 66.2% sensitivity 75.8% specificity predicting the presence of CIP. In our conclusions, we discuss the relevance of evaluating CIP in all cocaine dependent-patients, and particularly in those fulfilling the clinical profile derived from our results. These findings could be useful for a clinical approach to the risks of psychotic states in cocaine-dependent patients.

A century ago, Kraepelin and Bleuler observed that schizophrenia is often antedated by "premorbid" abnormalities. In this study we explore how the childhood neurodevelopmental problems found in patients with schizophrenia relate to the current concept of autism spectrum disorder (ASD). Forty-six young adult individuals with clinical diagnoses of schizophrenic psychotic disorders were assessed. The Structured Clinical Interview for DSM Disorders (SCID-I) was used in face-to-face psychiatric examination of each individual. In 32 of the 46 cases (70%), collateral information was provided by one or both parents. The Diagnostic Interview for Social and Communication Disorders - eleventh version (DISCO-11) was used when interviewing these relatives. This instrument covers, in considerable depth, childhood development, adaptive functioning, and symptoms of ASD - current and lifetime. There is a strict algorithm for ASD diagnosis. About half of the cases with schizophrenic psychosis had ASD according to the results of the parental interview. The rate of ASD was strikingly high (60%) in the group with a SCID-I diagnosis of schizophrenia paranoid type. The findings underscore the need to revisit the DSM's "either or" stance between ASD and schizophrenia.

We investigated prospectively documented parental age and bipolar disorder (BD) in a multi-ethnic birth cohort. The study was based on a nested case-control design from the Child Health and Development Study (CHDS) birth cohort from 1959 to 1966. Potential cases with BD were ascertained by database linkages between CHDS, Kaiser Permanente Medical Care Plan (KPNC), and Alameda County Behavioral Health Care Services, and mailed questionnaires. Consensus diagnoses with the SCID for DSM-IV-TR were made. The total number of BD cases was 94. Controls (N=746) were selected from the birth cohort and matched on date of birth, sex, and KPNC membership or residence in Alameda County. For every 10-year increment of paternal age, there was no significant association with BD, adjusting for maternal age. There was also no significant association between maternal age, modeled in 10-year increments, and risk of BD after adjustment for paternal age and maternal race, although there was a suggestion for a protective relationship between increasing maternal age and BD with psychotic features. These findings suggest that if advanced paternal age is a risk factor for BD, the strength of the relationship is small.

Epidemiological data show that up to 20-30% of patients with psychogenic nonepileptic seizures (PNESs), resembling drug-resistant epilepsy (DRE), are referred to tertiary epilepsy centers. Furthermore, both disorders present high psychiatric comorbidity, and video-EEG is the gold standard to make differential diagnoses. In this study, we described and compared the clinical presentation and the frequency of psychiatric disorders codified in DSM IV in two groups of patients, one with PNESs and the other with DRE, admitted in a tertiary care epilepsy center of Buenos Aires, Argentina. We included 35 patients with PNESs and 49 with DRE; all were admitted in the video-EEG unit in order to confirm an epilepsy diagnosis and determine surgical treatment possibilities. All patients underwent a neurological and psychiatric assessment, according to standardized protocol (SCID I and II; DSM IV criteria). Student's t test was performed to compare continuous variables and Chi square test to compare qualitative variables. In this study, 33 (67%) patients with DRE and 35 (100%) patients with PNESs met criteria for at least one disorder codified in Axis I of DSM IV (p=0.003). Differences in the frequency of psychiatric disorder presentation were found between groups. Anxiety disorders (16.32% vs 40%; p=0.015), trauma history (24.5% vs 48.57%; p=0.02), posttraumatic stress disorder (4.08% vs 22.85%; p=0.009), and personality cluster B disorders (18.37% vs 42.86%; p=0.02) were more frequent in the group with PNESs. Psychotic disorders were more frequent in the group with DRE (20.4% vs 2.85%; p=0.019). Depression was equally prevalent in both groups. Standardized psychiatric assessment provides information that could be used by the mental health professional who receives the referral in order to improve quality of care and smooth transitions to proper PNES treatment, which should include a multidisciplinary approach including neurology and psychiatry.

The aim of this study was to investigate the presence of premorbid Personality Disorder (PD) and its relationship with clinical correlates in patients with Delusional Disorder (DD). Eighty-six outpatients with DD whose diagnoses were confirmed using the Structured Clinical Interview for DSM-IV Axis I (SCID-I) Disorders (psychosis module) were evaluated for premorbid PD utilizing the Standardized Assessment of Personality (SAP). Psychopathology was assessed using Module B of SCID-I and the Positive and Negative Syndrome Scale (PANSS); psychosocial functioning was evaluated with the Global Assessment of Functioning scale. Premorbid intelligence was assessed using the Wechsler Adult Intelligence Scale-Third Edition, vocabulary subtest. A sociodemographic-clinical questionnaire was completed. Sixty-four percent of the patients had at least one premorbid PD, the most common being paranoid PD (38.4%), followed by schizoid PD (12.8%). The presence of at least one premorbid PD was significantly associated with higher scores for psychopathology, in particular, on the affective dimension of DD symptoms. However, the presence of premorbid PD was not associated with psychosocial functioning. Each of the premorbid PD was associated with different psychopathological profiles. Premorbid PD is a relevant phenomenon in DD, given its high prevalence and comorbidity, its influence on clinical correlates and its potential ability to predict specific sub-syndromes.

The aim of the study was to investigate the possible association between polymorphisms of HPA axis genes-CRHR1 (corticotrophin-releasing hormone receptor), NR3C1 (glucocorticoid receptor) and AVPR1B (arginine vasopressin receptor) and dimensions of bipolar disorder assessed by OPCRIT. We examined 560 patients with diagnosis of bipolar disorder (n=457) and unipolar disorder (n=103). Diagnosis was established by SCID and OPCRIT. We found association between polymorphisms of AVPR1b gene and psychotic dimension and CRHR1 polymorphisms and excitement and psychotic dimension. Our results suggest possible involvement of the AVPR1b and CRHR1 genes in the ethiology of psychotic features in the course of affective disorders, and possible involvement of CRHR1 gene in the ethiology of bipolar disorder.

Cannabis use seems to play a causal role in the development of psychotic disorders. Recent evidence suggests that it may also precipitate onset in bipolar disorder. We here investigate if there is a dose-response relationship between cannabis use and age at onset in bipolar disorder, and whether there are interactions between cannabis use and illness characteristics (presenting polarity and presence of psychosis). Consecutively recruited patients with a DSM-IV, SCID verified diagnosis of bipolar I, II or NOS disorder (n=324) participated. Two-way ANCOVAS were used to investigate the effect of levels of cannabis use (<10 times during one month lifetime, >10 times during one month lifetime or a cannabis use disorder) on age at onset, including interaction effects with illness characteristics, while controlling for possible confounders. There was a significant association indicating a dose-response relationship between cannabis use and age at onset, which remained statistically significant after controlling for possible confounders (gender, bipolar subtype, family history of severe mental illness and alcohol or other substance use disorders). There were no interaction effects between cannabis use and presenting polarity or presence of psychosis. Doses of cannabis used may affect the age at onset of bipolar disorder.

Assessment of depression in individuals who are considered to be at clinical high risk (CHR) for psychosis is important as high rates of depression have been reported in CHR individuals. The Calgary Depression Scale (CDSS) is the most widely used scale for assessing depression in schizophrenia. It has excellent psychometric properties, internal consistency, inter-rater reliability, sensitivity, specificity, and discriminant and convergent validity. The aim of this study was to test the reliability and validity of the CDSS in a sample of youth at CHR for psychosis. Participants were assessed for depression, presence of axis 1 mood disorders, and prodromal symptoms using the CDSS, the Structured Clinical Interview for DSM-IV Disorders (SCID-1), and the Scale of Prodromal Symptoms (SOPS). The CDSS total score as well as all individual items, except "guilty ideas of reference," were significantly associated with the presence of a major depressive disorder. Significant correlations were observed between CDSS total score and the dysphoric mood item on the SOPS. There was some evidence of overlap between the CDSS and both attenuated positive symptoms and negative symptoms as assessed by the SOPS. It is concluded that CDSS is a reliable scale suitable for assessing depression in individuals considered to be at CHR for psychosis.

Suicidal behavior often accompanies both borderline personality disorder (BPD) and severe mood disorders, and comorbidity between the two appears to further increase suicide risk. The current study aims to quantify the risk of suicidality conferred by comorbid BPD diagnosis or features in three affective disorders: major depressive disorder (MDD), bipolar disorder (BP) and schizoaffective disorder. One hundred forty-nine (149) psychiatric inpatients were assessed by SCID I and II, and the Columbia Suicide Severity Rating Scale. Logistic regression analyses investigated the associations between previous suicide attempt and BPD diagnosis or features in patients with MDD, BP, and schizoaffective disorder, as well as a history of manic or major depressive episodes, and psychotic symptoms. Comorbid BPD diagnosis significantly increased suicide risk in the whole sample, and in those with MDD, BP, and history of depressive episode or psychotic symptoms. Each additional borderline feature also increased risk of past suicide attempt in these same groups (excepting BP) and in those with a previous manic episode. Of the BPD criteria, only unstable relationships and impulsivity independently predicted past suicide attempt. Overall, among patients with severe mood disorders, the presence of comorbid BPD features or disorder appears to substantially increase the risk of suicide attempts.
