The suicidality continuum in a large sample of obsessive-compulsive disorder (OCD) patients.

Obsessive-compulsive disorder (OCD) has a chronic course leading to huge impact in the patient's functioning. Suicidal thoughts and attempts are much more frequent in OCD subjects than once thought before. To empirically investigate whether the suicidal phenomena could be analyzed as a suicidality severity continuum and its association with obsessive-compulsive (OC) symptom dimensions and quality of life (QoL), in a large OCD sample. Cross-sectional study with 548 patients diagnosed with OCD according to the DSM-IV criteria, interviewed in the Brazilian OCD Consortium (C-TOC) sites. Patients were evaluated by OCD experts using standardized instruments including: Yale-Brown Obsessive-Compulsive Scale (YBOCS); Dimensional Yale-Brown Obsessive-Compulsive Scale (DYBOCS); Beck Depression and Anxiety Inventories; Structured Clinical Interview for DSM-IV (SCID); and the SF-36 QoL Health Survey. There were extremely high correlations between all the suicidal phenomena. OCD patients with suicidality had significantly lower QoL, higher severity in the "sexual/religious", "aggression" and "symmetry/ordering" OC symptom dimensions, higher BDI and BA scores and a higher frequency of suicide attempts in a family member. In the regression analysis, the factors that most impacted suicidality were the sexual dimension severity, the SF-36 QoL Mental Health domain, the severity of depressive symptoms and a relative with an attempted suicide history. Suicidality could be analyzed as a severity continuum and patients should be carefully monitored since they present with suicidal ideation. Lower QoL scores, higher scores on the sexual dimension and a family history of suicide attempts should be considered as risk factors for suicidality among OCD patients.

Early maladaptive schemas and suicidal risk in an Iranian sample of patients with obsessive-compulsive disorder.

There are few studies on suicidal risk and its related factors in patients diagnosed with obsessive-compulsive disorder (OCD). This study investigated the associations of early maladaptive schemas, OC symptom dimensions, OCD severity, depression and anxiety with suicidality (i.e., suicidal ideation and suicide attempts) in OCD patients. Sixty OCD outpatients completed the Scale for Suicide Ideation (SSI), the Young Schema Questionnaire-Short Form (YSQ-SF), the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), the Dimensional Obsessive-Compulsive Scale (DOCS) and the Depression Anxiety Stress Scales (DASS-21). 51.7% of patients had lifetime suicide attempts and 75% had suicidal ideation. OCD patients with lifetime suicide attempts exhibited significantly higher scores on early maladaptive schemas than those without such attempts. Logistic regression analysis revealed that the mistrust/abuse schema and the OC symptom dimension of unacceptable thoughts explained lifetime suicide attempts. The mistrust/abuse schema, unacceptable thoughts and depression significantly predicted suicidal ideation. These findings indicated that the mistrust/abuse schema may contribute to high suicidality in OCD patients. Also, patients suffering from unacceptable thoughts need to be assessed more carefully for warning signs of suicide.

Clinical features of pure obsessive-compulsive disorder.

Psychiatric comorbidity is the rule in obsessive-compulsive disorder (OCD); however, very few studies have evaluated the clinical characteristics of patients with no co-occurring disorders (non-comorbid or "pure" OCD). The aim of this study was to estimate the prevalence of pure cases in a large multicenter sample of OCD patients and compare the sociodemographic and clinical characteristics of individuals with and without any lifetime axis I comorbidity. A cross-sectional study with 955 adult patients of the Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders (C-TOC). Assessment instruments included the Yale-Brown Obsessive-Compulsive Scale, the Dimensional Yale-Brown Obsessive-Compulsive Scale, The USP-Sensory Phenomena Scale and the Brown Assessment of Beliefs Scale. Comorbidities were evaluated using the Structured Clinical Interview for DSM-IV Axis I Disorders. Bivariate analyses were followed by logistic regression. Only 74 patients (7.7%) presented pure OCD. Compared with those presenting at least one lifetime comorbidity (881, 92.3%), non-comorbid patients were more likely to be female and to be working, reported less traumatic experiences and presented lower scores in the Y-BOCS obsession subscale and in total DY-BOCS scores. All symptom dimensions except contamination-cleaning and hoarding were less severe in non-comorbid patients. They also presented less severe depression and anxiety, lower suicidality and less previous treatments. In the logistic regression, the following variables predicted pure OCD: sex, severity of depressive and anxious symptoms, previous suicidal thoughts and psychotherapy. Pure OCD patients were the minority in this large sample and were characterized by female sex, less severe depressive and anxious symptoms, less suicidal thoughts and less use of psychotherapy as a treatment modality. The implications of these findings for clinical practice are discussed.

Bipolar disorder comorbidity in patients with obsessive-compulsive disorder: Prevalence and predictors.

Patients with obsessive-compulsive disorder (OCD) often present with comorbidities, mainly anxiety and affective disorders, which may influence OCD course, help-seeking and treatment response. Some authors have studied bipolar disorder (BD) comorbidity in patients with OCD, but usually in small samples. The objective was to estimate the lifetime prevalence of BD in a large clinical sample of OCD patients, and to compare demographic and clinical features of patients with and without BD comorbidity. This cross-sectional study with 955 adult OCD patients from the Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders (C-TOC) used several assessment instruments, including the Yale-Brown Obsessive-Compulsive Scale, the Dimensional Yale-Brown Obsessive-Compulsive Scale, the Beck Depression and Anxiety Inventories, and the Structured Clinical Interview for DSM-IV Axis I Disorders. Descriptive and bivariate analyses were followed by logistic regression. The lifetime prevalence of BD was 7.75% (N = 74). The variables that were independently associated with BD comorbidity were: panic disorder with agoraphobia, impulse control disorders, and suicide attempts. The cross-sectional design does not permit causal inferences; the external validity may be limited, as the participants were from tertiary services. Despite the large sample size, some analyses may have been underpowered due to the relatively low prevalence of the outcome and of some explanatory variables. Patients with OCD comorbid with BD have some clinical features indicative of greater severity, including higher suicide risk, and require a careful therapeutic approach for the appropriate treatment of both disorders.

The relation of childhood trauma to suicide ideation in patients suffering from obsessive-compulsive disorder with lifetime suicide attempts.

The aim of this study was to evaluate the relations of childhood trauma (CT) and obsessive-compulsive (OC) symptom dimensions to suicide ideation in patients with obsessive-compulsive disorder (OCD). Seventy OCD outpatients with lifetime suicide attempts and 60 controls were included. Participants completed the Scale for Suicide Ideation (SSI), the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), the Dimensional Obsessive-Compulsive Scale (DOCS) and the Depression Anxiety Stress Scales (DASS-21). Among OCD patients, 97.1% had current suicide ideation. OCD patients revealed higher scores on CT, suicide ideation, depression and anxiety than controls. The CT history of sexual abuse (SA) and OC symptom dimension of unacceptable thoughts explained suicide ideation. It was concluded that SA and unacceptable thoughts may contribute to high suicidality and have important implications for the assessment and treatment of suicide risk in OCD patients with lifetime suicide attempts.
