[Phenomenology of obsessions and compulsions. Experimental diagnosis of obsessive compulsive neurosis. I (author's transl)].

Obsessive-compulsive phenomena occur in 'normal,' neurotic and psychotic individuals. Operational definition, quantitative assessment, and diagnostic evaluation are still unsatisfactory, particularly with regard to differentiation of obsessive-compulsive phenomena (phenomenology), differentiation of trait and symptom factors, and evaluation of different obsessive-compulsive factors in the various kinds of neuroses. Our investigation of phenomenology differs from previous similar ones in basically two aspects: The newly developed obsessive-compulsive checklist covers the whole range of obsessions and compulsions, and questionnaire items of the checklist are operationally difined without reference to constructs from theories of personality or from psychopathology. Results include: Two-thirds of all patients suffer from combined obsessions and compulsions; factorial analysis reveals five symptom factors which are quite different from factor analytic results of previous studies; depression and phobias constitute a factor by themselves; checklist ratings and factor analytic results show the necessity for and basis of a new self-rating questionnaire to substitute for those currently in use. Implications of these results for future research in psychopathology as well as treatment evaluation are discussed.

Do patients suffering from obsessions alone differ from other obsessive-compulsives?

The aim of this study was to determine whether a group of 48 patients with obsessions and compulsions differed from a group of 26 patients with obsessions alone, on the basis of demographic variables, variables relating to obsessive-compulsive neurosis, psychological variables and treatment outcome. It was found that they differed significantly in the following areas: marital status, level of education, age at onset of complaints, psychoactive medication taken when admitted for treatment, severity of obsessive-compulsive complaints, depression and intelligence. No difference was found as far as treatment outcome was concerned. Patients suffering from obsessions alone, would appear to form a distinct sub-group within the group of obsessive-compulsive patients as a whole.

Is there an obsessive psychosis? Aetiological and prognostic factors of an atypical form of obsessive-compulsive neurosis.

The study explores whether an atypical form of obsessional illness can be delineated and separated from the conventional form of obsessive-compulsive neurosis (OCN). From a group of 45 obsessive patients, 8 were selected on the basis of 3 criteria: presence of a severely debilitating main obsessive symptom; bordering on the delusional; no schizophrenic symptoms. Assessment and outcome measures included the Psychiatric Questionnaire, the Leyton Obsessional Inventory, Fear Survey Schedule, and IPAT Self-Analysis Form. Self-assessment forms allowed patients to make social adjustment and neurotic symptom ratings. In a multimodal approach, patients were assigned to behavioural and pharmacological treatments on the basis of severity. Reassessment took place after 50 sessions of therapy. Results of analysis of variance statistics indicated that the atypical group had a more malignant form of illness, with more varied and severe obsessions. A poorer prognosis for the atypical group was indicated by: greater social maladjustment, poor employment records, illness of longer duration showing no remissions despite more courses of treatment, and poor response to treatment throughout. The atypical group manifested fewer characteristic features of OCN (example: fewer precipitating events). On the other hand, schizophrenia was not imputed, although delusion-like experiences in the atypical group suggest a psychotic form of illness. The term "obsessive psychosis" suggested by Strauss and recently investigated by Weiss et al and Robinson et al is proposed for our atypical group. Results are compared with those of other investigators. It is concluded that the delineation of a subgroup of obsessional illness is desirable for research and therapy since a form of atypical obsessional illness or obsessive psychosis can be differentiated on aetiological, phenomenological and prognostic factors.

Clinical features distinguishing patients with Tourette's syndrome and obsessive-compulsive disorder from patients with obsessive-compulsive disorder without tics.

OBJECTIVE: It is not clear whether obsessive-compulsive disorder (OCD) in the context of Tourette's syndrome (TS) is the same as that disorder found in patients with OCD alone. This study evaluated the severity and characteristics of the obsessive-compulsive symptoms in adult patients with OCD and TS compared to adult patients with OCD alone. METHOD: Thirteen subjects with both DSM-III-R TS and OCD and 13 subjects with OCD alone were recruited. Obsessive-compulsive severity was determined by using the Yale-Brown Obsessive Compulsive Scale. The Tourette Syndrome Association Unified Tic Rating Scale was administered to determine tic severity, and the adult version of the Attention Deficit and Hyperactivity Checklist was used to detect a history of childhood attention-deficit hyperactivity disorder (ADHD). RESULTS: Subjects with OCD alone had very few obsessions and compulsions that were not also experienced by subjects with both TS and OCD. In contrast, subjects with TS and OCD were significantly more likely to report obsessions involving nonviolent images, excessive concern with appearance, and need for symmetry. Touching, blinking or staring, and counting compulsions were also significantly more common in this group. Eight subjects with OCD and TS had a childhood history of ADHD, compared to none of the pure OCD subjects. CONCLUSION: There are subtle but definite differences in symptomatology of subjects with pure OCD compared to those with OCD and TS consistent with putative differences in pathophysiology between the 2 groups, i.e., abnormalities in the serotonergic system in OCD patients and serotonergic and dopaminergic abnormalities in those with OCD and TS. These observations may be consistent with genetic heterogeneity within both OCD and TS.

Obsessive compulsive disorder in huntington disease: a case of isolated obsessions successfully treated with sertraline.

OBJECTIVE: To report about a patient with Huntington disease (HD) in combination with obsessions who was successfully treated with a selective serotonin reuptake inhibitor. BACKGROUND: Obsessive compulsive disorder (OCD) has rarely been reported in association with HD, and little is known about the treatment of patients with OCD symptoms and HD. METHODS: We describe a 42-year-old woman who experienced isolated obsessive thoughts about killing her neighbor 10 years after the onset of her genetically confirmed HD. RESULTS: Sertraline was prescribed at a daily dose of 150 mg with a complete remission of obsessive ideas within 4 weeks of treatment. CONCLUSIONS: The basal ganglia are known to play an important role in the pathogenesis of OCD and HD. Thus, it is conceivable that a degeneration of the caudate nucleus as in HD may also account for obsessive and compulsive symptoms in this disorder. To our knowledge, this is the first report about a patient with HD in combination with obsessions alone who was successfully treated with a selective serotonin reuptake inhibitor. However, the association of OCD with HD warrants further systematic evaluation.

The relationship of the Yale-Brown Obsessive Compulsive Scale (YBOCS) to other measures of obsessive compulsive symptoms in a nonclinical population.

The Yale-Brown Obsessive Compulsive Scale (YBOCS; Goodman, Price, Rasmussen, & Mazure, 1989a) is an interview-based rating scale measuring severity of obsessive compulsive disorder (OCD). Because it is independent of the number and type of OCD symptoms and minimizes confounding with other types of symptoms, it has become the "gold standard" for assessing the outcome of behavioral and pharmacological treatments. This study was designed to further validate the YBOCS in relation to self-report measures of obsessive compulsive phenomena in a nonclinical population. Among a group of 45 female college students, the three primary YBOCS measures (obsessions, compulsions, and total score) were internally consistent and correlated moderately to strongly with self-report measures of obsessive compulsive phenomena that have been used in previous research. The compulsive subscale of the YBOCS showed the lowest correlation with self-report measures sharing only 25% of the common variance. This measure is appropriate for use with nonclinical samples and may prove superior to other instruments for detecting the presence and severity of obsessive and compulsive symptoms.

The Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS): an instrument for assessing obsessive-compulsive symptom dimensions.

Obsessive-compulsive disorder (OCD) encompasses a broad range of symptoms representing multiple domains. This complex phenotype can be summarized using a few consistent and temporally stable symptom dimensions. The objective of this study was to assess the psychometric properties of the Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS). This scale measures the presence and severity of obsessive-compulsive (OC) symptoms within six distinct dimensions that combine thematically related obsessions and compulsions. The DY-BOCS includes portions to be used as a self-report instrument and portions to be used by expert raters, including global ratings of OC symptom severity and overall impairment. We assessed 137 patients with a Diagnostic and Statistical Manual-IV diagnosis of OCD, aged 6-69 years, from sites in the USA, Canada and Brazil. Estimates of the reliability and validity of both the expert and self-report versions of the DY-BOCS were calculated and stratified according to age (pediatric vs. adult subjects). The internal consistency of each of the six symptom dimensions and the global severity score were excellent. The inter-rater agreement was also excellent for all component scores. Self-report and expert ratings were highly intercorrelated. The global DY-BOCS score was highly correlated with the total Yale-Brown Obsessive-Compulsive Scale score (Pearson r = 0.82, P<0.0001). Severity scores for individual symptom dimensions were largely independent of one another, only modestly correlated with the global ratings, and were also differentially related to ratings of depression, anxiety and tic severity. No major differences were observed when the results were stratified by age. These results indicate that the DY-BOCS is a reliable and valid instrument for assessing multiple aspects of OCD symptom severity in natural history, neuroimaging, treatment response and genetic studies when administered by expert clinicians or their highly trained staff.

Relationship of obsessive-compulsive personality to obsessive-compulsive disorder: a review of the literature.

The nature of the relationship between obsessive-compulsive personality and obsessive-compulsive disorder has been the subject of considerable debate. The present article dealt with clinical opinion and reviewed empirical data bearing on this issue. It was concluded that, although the two clinical entities bear a surface similarity in terms of shared behavioral features and defenses, obsessive-compulsive personality is neither a necessary nor sufficient factor in the development of obsessive-compulsive disorder, though the latter appears to be more frequently associated with premorbid obsessive-compulsive personality patterns than with other personality patterns. Suggestions for future research study are made.

Obsessive-compulsive aspects of craving: development of the Obsessive Compulsive Drinking Scale.

"Craving" for alcohol needs improved definition and measurement. This review provides a rationale for considering at least certain aspects of craving as having obsessive and compulsive features. As such, there may be phenomenological, but not necessarily etiological, overlap with obsessive-compulsive disorder. There are increasing data that suggest a neuroanatomical overlap between addiction/craving and obsessive-compulsive symptoms. The self-rated Obsessive Compulsive Drinking Scale (OCDS), based on the Yale-Brown Obsessive Compulsive Scale for heavy drinking interview (YBOCS-hd), was developed to assist in the examination of certain aspects of "craving" in alcoholics. The development, reliability, face validity, congruent validity and predictive validity of the OCDS are presented and discussed in this paper. The utility of the OCDS as a measurement tool in cognitive-behavioral and pharmacological alcoholism treatment research is highlighted. The potential of this instrument as a research and clinical tool for the understanding and evaluation of alcohol dependence needs further evaluation.

Gilles de la Tourette's syndrome with and without obsessive-compulsive disorder compared with obsessive-compulsive disorder without tics: which symptoms discriminate?

Stereotyped repetitive behaviors occur in Gilles de la Tourette's Syndrome (GTS) and obsessive-compulsive disorder (OCD). The present study was undertaken to compare the distribution of obsessive-compulsive and Tourette-related impulsive behaviors in GTS with (+) OCD, GTS without (-) OCD, tic-free OCD, and control subjects. Fourteen GTS + OCD, 18 GTS-OCD, 21 OCD-tic, and 29 control subjects were evaluated using a semistructured interview designed to assess GTS and OCD-related repetitive behaviors. Each reported item was evaluated on the presence of anxiety and goal-directedness. This information was subsequently used to define whether the repetitive behavior was an (anxiety-related) obsession or compulsion, or a (non-anxiety-related) OC-like behavior, impulsion. GTS + OCD subjects reported more overall Tourette-related impulsions than OCD-tic subjects, i.e., more mental play, echophenomena, and touching behaviors but similar frequencies of typical obsessive-compulsive behaviors. Further, GTS + OCD subjects exhibited more overall repetitive behaviors than GTS-OCD subjects, i.e., more Tourette-related impulsions as well as more obsessive-compulsive behaviors. The distribution of symptoms is similar in GTS with and without OCD, and differs from tic-free OCD. These differences suggest that GTS with OCD constitutes a form of GTS, not of OCD, although the possibility that GTS + OCD patients constitute a subgroup distinct from GTS and from OCD can not be excluded by this phenomenological study. Specific non-anxiety-related impulsions seem to discriminate between GTS and OCD-tic individuals. These impulsions possibly reflect differences in underlying mechanisms between GTS and OCD-tics.

Preferential aggregation of obsessive-compulsive spectrum disorders in schizophrenia patients with obsessive-compulsive disorder.

OBJECTIVE: To validate a complex association between schizophrenia and obsessive-compulsive disorder (OCD). METHOD: We used the Structured Clinical Interview for DSM-IV Axis I disorders to compare the rate of OCD spectrum and additional Axis I disorders in 100 patients who met criteria for both schizophrenia and OCD, non-OCD schizophrenia (n = 100), and OCD (n = 35). RESULTS: There was a robust between-group difference in the number of patients with one or more OCD spectrum disorders (schizo-obsessive n = 30, compared with schizophrenia n = 8; P = 0.001), that is, higher rates of body dysmorphic (8% compared with 0%) and tic (16% compared with 4%) disorders. No difference was revealed in affective, anxiety, and substance use disorders. We found comparable rates of OCD spectrum disorders in the schizo-obsessive and OCD groups (30% and 42.8%, respectively; P = 0.32). CONCLUSION: Preferential aggregation of OCD spectrum disorders in the schizo-obsessive group supports this unique clinical association. Whether a schizo-obsessive interface represents comorbidity or a specific subtype of schizophrenia warrants further investigation.

[Phenomenology of obsessive-compulsive disorders. Forms and characteristics of obsessions and compulsions in East Turkey].

The aim of our study was to analyse the obsessions and compulsions of patients diagnosed as Obsessive-Compulsive Disorder in terms of their forms and their contents in Eastern Turkey. Forms and contents of 181 obsessions and 164 compulsions found in 108 patients were classified by using the classification system developed by Khanna and Channabasavanna. Dirt and contamination fear was the most common obsessive theme, followed by religion. Washing compulsion content was found in nearly two thirds of the patients then followed by specific activities (praying, counting and touching). Our data was concordant with previous studies except for religious obsessions in particular, second in frequency.

Comparison of obsessions and compulsions in patients with anorexia nervosa and obsessive compulsive disorder.

Patients with anorexia nervosa (n = 18) and patients with obsessive-compulsive disorder (OCD) (n = 16) had similar scores on the Yale-Brown Obsessive Compulsive Scale (19 + or - 9 vs. 22 + or - 6). This suggests that these disorders have similar magnitude of impairment from obsessions and compulsions; however, OCD patients endorsed a wide variety of obsessions and compulsions, whereas anorexics tended to endorse symptoms that were related to symmetry and order.

Cluster analysis of obsessive-compulsive spectrum disorders in patients with obsessive-compulsive disorder: clinical and genetic correlates.

BACKGROUND: Comorbidity of certain obsessive-compulsive spectrum disorders (OCSDs; such as Tourette's disorder) in obsessive-compulsive disorder (OCD) may serve to define important OCD subtypes characterized by differing phenomenology and neurobiological mechanisms. Comorbidity of the putative OCSDs in OCD has, however, not often been systematically investigated. METHODS: The Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition , Axis I Disorders-Patient Version as well as a Structured Clinical Interview for Putative OCSDs (SCID-OCSD) were administered to 210 adult patients with OCD (N = 210, 102 men and 108 women; mean age, 35.7 +/- 13.3). A subset of Caucasian subjects (with OCD, n = 171; control subjects, n = 168), including subjects from the genetically homogeneous Afrikaner population (with OCD, n = 77; control subjects, n = 144), was genotyped for polymorphisms in genes involved in monoamine function. Because the items of the SCID-OCSD are binary (present/absent), a cluster analysis (Ward's method) using the items of SCID-OCSD was conducted. The association of identified clusters with demographic variables (age, gender), clinical variables (age of onset, obsessive-compulsive symptom severity and dimensions, level of insight, temperament/character, treatment response), and monoaminergic genotypes was examined. RESULTS: Cluster analysis of the OCSDs in our sample of patients with OCD identified 3 separate clusters at a 1.1 linkage distance level. The 3 clusters were named as follows: (1) "reward deficiency" (including trichotillomania, Tourette's disorder, pathological gambling, and hypersexual disorder), (2) "impulsivity" (including compulsive shopping, kleptomania, eating disorders, self-injury, and intermittent explosive disorder), and (3) "somatic" (including body dysmorphic disorder and hypochondriasis). Several significant associations were found between cluster scores and other variables; for example, cluster I scores were associated with earlier age of onset of OCD and the presence of tics, cluster II scores were associated with female gender and childhood emotional abuse, and cluster III scores were associated with less insight and with somatic obsessions and compulsions. However, none of these clusters were associated with any particular genetic variant. CONCLUSION: Analysis of comorbid OCSDs in OCD suggested that these lie on a number of different dimensions. These dimensions are partially consistent with previous theoretical approaches taken toward classifying OCD spectrum disorders. The lack of genetic validation of these clusters in the present study may indicate the involvement of other, as yet untested, genes. Further genetic and cluster analyses of comorbid OCSDs in OCD may ultimately contribute to a better delineation of OCD endophenotypes.

Schizo-obsessive and obsessive-compulsive disorder: comparison of clinical characteristics and neurological soft signs.

The purpose of the study was to examine whether schizophrenia with obsessive-compulsive disorder (OCD) represents a severe form of OCD-spectrum disorders on the basis of neurological soft signs (NSS) and obsessive-compulsive (OC) symptoms. Sixteen patients with OCD-schizophrenia, 25 OCD patients and 23 healthy controls (HC) were studied. Scales for the Assessment of Positive (SAPS) and Negative Symptoms (SANS), Clinical Global Impressions Scale and Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) were used to assess the schizophrenic and OC symptomatology. NSS were evaluated with the Neurological Evaluation Scale (NES). OCD-schizophrenics had significantly higher scores on total NES than HC. The patients with OCD were more likely to have total Y-BOCS and subscale scores of compulsions than patients with OCD-schizophrenia. The rate of symmetry obsessions and cleaning/washing compulsions were significantly higher in patients with OCD compared to OCD-schizophrenics. We have found no correlation of OC symptoms with schizophrenic symptomatology. Our findings may suggest that OCD-schizophrenia is a distinct subtype of schizophrenia, not a more severe form of OCD-spectrum disorder.

Advances in the neurobiology of obsessive-compulsive disorder. Implications for conceptualizing putative obsessive-compulsive and spectrum disorders.

Several approaches to the spectrum of obsessive-compulsive spectrum disorders have been put forward, each based on a rather different framework. To some extent, overlaps exist among these approaches, indicating that the neurobiology of OCD and related disorders is increasingly consolidated; however, important differences exist between these approaches, and many questions are unanswered, demonstrating that more work is necessary to fully delineate OCD and its subtypes and their relationships to other putative obsessive compulsive spectrum disorders. Despite the need for substantial additional research on the neurobiology of the obsessive-compulsive spectrum, this construct already has heuristic value in the clinical and research setting. It reminds clinicians to ask OCD patients about comorbid spectrum disorders, and it suggests the possible value of anti-OCD agents and behavioral techniques in patients for whom treatments were previously unavailable. It reminds investigators to consider possibly overlapping and differentiating mechanisms in several disorders. Ultimately, the delineation of such mechanisms will allow for a more rigorous approach to the putative obsessive-compulsive spectrum disorders.

Severity of obsessive-compulsive symptoms is related to self-directedness character trait in obsessive-compulsive disorder.

OBJECTIVE: The present study examined the psychobiological Temperament and Character model of personality on obsessive-compulsive disorder (OCD) patients, as well as the relation of temperament and/or character dimensions on the severity of obsessive-compulsive symptoms. METHODS: Fifty-four subjects diagnosed with OCD, were assessed with the Temperament and Character Inventory, the Yale-Brown Obsessive-Compulsive scale and the Hamilton Rating Scales for depression and anxiety. RESULTS: Compared with controls, OCD subjects displayed increased harm avoidance and lower self-directedness and cooperativeness. Low self-directedness and high Hamilton depression scores were associated with increased severity of obsessive-compulsive symptoms. CONCLUSION: The Temperament and Character profile of OCD patients characterized in the present study was in agreement with previous reports using the same personality model and can be linked to some of their behavioral features. Furthermore, our data provides support of the influence that some personality traits may have on the severity of OCD symptoms.

Screening for obsessive and compulsive symptoms: validation of the Clark-Beck Obsessive-Compulsive Inventory.

The 25-item Clark-Beck Obsessive-Compulsive Inventory (CBOCI) was developed to assess the frequency and severity of obsessive and compulsive symptoms. The measure uses a graded-response format to assess core symptom features of obsessive-compulsive disorder (OCD) based on Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) criteria and current cognitive-behavioral formulations. Revisions were made to the CBOCI on the basis of psychometric and item analyses of an initial pilot study of clinical and nonclinical participants. The construct validity of the revised CBOCI was supported in a subsequent validation study involving OCD, nonobsessional clinical, and nonclinical samples. A principal-factor analysis of the 25 items found 2 highly correlated factors of Obsessions and Compulsions. OCD patients scored significantly higher on the measure than nonobsessional anxious, depressed, and nonclinical samples. The questionnaire had strong convergent validity with other OCD symptom measures but more modest discriminant validity.
