A phenomenological analysis of symptoms in obsessive-compulsive neurosis

A study of doubt in obsessive-compulsive disorder

BACKGROUND AND OBJECTIVES

Obsessive-compulsive disorder (OCD) has been referred to as the "doubting disease," yet there has been little foundational research on its phenomenology and characteristics. Studies of doubt have relied on researchers' idiosyncratic conceptualizations of the construct, resulting in varied assessment methods and different prevalence rates (11-75%). We examined the nature and characteristics of doubt in people with clinical and subclinical OCD so as to identify its nature and characteristics, and factors that may be unique to OCD.

METHODS

A semi-structured interview about doubt was administered to people with OCD (N = 44) and with subclinical OCD (N = 21).

RESULTS

Doubt was highly prevalent and manifested as a form of obsession, uncertainty about whether a task was done properly, and/or lack of confidence in memory and perceptions. All participants took action to resolve doubt and/or proactively pre-empt or reduce future doubt. Doubt was deeply connected to negative core beliefs about the self. The groups did not differ on their experience of doubt, except that greater symptom severity was associated with greater interference from doubt, less ability to resist it, and less success of proactive, but not reactive, strategies to manage it.

LIMITATIONS

We relied on retrospective report, and the subclinical group was relatively small.

CONCLUSIONS

In subclinical and clinical OCD, doubt is pervasive, manifests in three domains, is connected to negative core beliefs, and is highly aversive. Continued empirical study of doubt is essential to proper assessment and to development of theories and treatment of OCD.

A New Scrupulosity Scale for the Dimensional Obsessive-Compulsive Scale (DOCS): Validation With Clinical and Nonclinical Samples

Scrupulous obsessions are a prominent presentation of obsessive-compulsive disorder (OCD). Previous conceptualizations of scrupulosity have indicated that it belongs to the unacceptable thoughts dimension, which pertains to sexual, violent, and religious obsessive themes. However, research suggests that scrupulous symptoms may differ from other unacceptable thoughts symptoms, necessitating the need for targeted and thorough assessment. We added a Scrupulous or Religious Thoughts subscale (DOCS-SR) to the Dimensional Obsessive-Compulsive Scale (DOCS) and tested its factorial structure, psychometric properties, and clinical correlates in a nonclinical and clinical sample. In the first study, nonclinical participants (N = 203) completed the DOCS-SR, which was subjected to an exploratory factor analysis. Analyses revealed that the DOCS-SR reflected a one-factor solution and possessed acceptable internal consistency, as well as strong convergent validity with clinical correlates of OCD. In the second study, we administered the DOCS, as well as the DOCS-SR to a clinical sample (N = 314). An exploratory factor analysis and confirmatory factor analysis both suggested that the four subscales and additional DOCS-SR represented a five-factor solution. Internal consistency and convergent validity were strong. The DOCS Unacceptable Thoughts subscale and the DOCS-SR shared a moderate correlation but evidenced differences in associations with other correlates. This suggested both convergent and divergent validity. Collectively, our results support the utility of examining the individual components of the unacceptable thoughts dimension of OCD for effective assessment and treatment planning.

Anxiety, OCD, delusions, and religiosity among the general public during the COVID-19 pandemic

The COVID-19 outbreak has not only affected the physical health of the public but also resulted in severe psychological outcomes. This study aims to investigate the psychological effects of the COVID-19 outbreak on Pakistan's general public. In order to identify the main psychological factors that have emerged due to the current pandemic, extensive literature and opinion pieces of psychologists were reviewed. After a thorough study of the existing scholarship, four main psychological factors were investigated: stress and anxiety, obsessive compulsive disorder (OCD), delusions of getting infected from the disease, and religiosity. A research survey was circulated among the sample population online. A total 356 valid responses were received in the period of two to three weeks. Findings showed that the respondents reported a moderate level of anxiety, occasional symptoms of OCD, and delusions. However, respondents showed a high inclination toward religion during the current pandemic situation. Furthermore, respondents highlighted a few other psychological factors, such as financial strain and loneliness, in the survey. The primary sources of COVID-19-related information were social media and television among the general public of Pakistan. Finally, guidelines and tips from the reviewed psychologists and psychiatrists on overcoming the highlighted psychological problems that have arisen due to the COVID-19 outbreak were summarised.

The relation of major depression, OCD, personality disorders and affective temperaments with Temporal lobe epilepsy

BACKGROUND

In patients with temporal lobe epilepsy (TLE), studies demonstrate frequent comorbidity with mood disorders, personality disorders (especially obsessive-compulsive disorder) and major depression, but there are conflicting findings. This study aimed to investigate psychiatric comorbidities and affective temperament among TLE patients and to explore the relationships between obsessive compulsive disorder, other personality disorders, major depression and affective temperament in order to clarify the mediator effect of TLE in these relationships.

METHODS

Thirty patients with TLE and 30 healthy volunteers were included. The Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), the Structured Clinical Interview for DSM III-R Axis II Disorders (SCID-II), Hamilton Anxiety (HAM-A) scale, Hamilton Depression (HAM-D) scale, Beck Suicidal Ideation Scale (BSSI) and Yale Brown Obsession Compulsion Scale (YBOCS) were applied and evaluated by a psychiatrist. Additionally, all individuals completed The Temperament Evaluation of Memphis, Pisa, Paris and San Diego (TEMPS-A).

RESULTS

Patients with temporal lobe epilepsy had higher scores in TEMPS-A, HAM-A, HAM-D, YBOCS and BSSI. Major depression, obsessive compulsive disorder and dependent and antisocial personality disorders were prevalent in patients. With respect to affective temperaments, depressive, cyclothymic and anxious temperaments were associated with obsessive compulsive disorder comorbidity; whereas, depressive and anxious temperaments were found to be associated with major depression comorbidity in patients with TLE. Furthermore, cluster A and cluster C personality disorders were associated with affective temperaments in patients with TLE. Affective temperaments had no correlation with illness duration, seizure frequency, depression severity and suicidal thoughts, but obsessions and compulsions. Suicidal thoughts were associated with obsessions and compulsions.

CONCLUSION

Affective temperaments are core personality traits with biological background and they may provide a foundation for psychiatric disorders, especially mood disorders. Considering that TLE originates from abnormalities in brain circuitry, it may form a basis for psychiatric disorders. Therefore, psychiatric evaluation to determine comorbidities may be beneficial to increase the quality of life of patients with TLE.

Impact of the COVID-19 pandemic on exposure and response prevention outcomes in adults and youth with obsessive-compulsive disorder

The COVID-19 pandemic has created novel mental health challenges for those with pre-existing problems including obsessive-compulsive disorder (OCD). Our study reports on clinician perceptions regarding the effect of the COVID-19 pandemic on patients with OCD receiving exposure and response prevention treatment (ERP) prior to and during the pandemic. Participating clinicians completed a survey which included questions adapted from National Institute of Mental Health-Global Obsessive-Compulsive Scale (NIMH-GOCS) and Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). Clinicians rated clinical features at treatment initiation, just prior to the pandemic, and mid-pandemic (July/August, 2020). Findings suggest that the COVID-19 pandemic was associated with attenuation of ERP progress from expected rates in most patients during first several months of the pandemic; clinicians estimated that 38% of their patients had symptoms worsen during the pandemic and 47% estimated that symptoms remained unchanged despite participating in ERP. Those who endured financial distress or were medically at-risk for severe COVID-19 disease had worse ERP course. Adults also had a worse ERP course during than pandemic than youth. Further research is needed to better understand the effect of the COVID-19 pandemic on OCD symptomatology and treatment trajectory post-pandemic.

Differentiation of 2 Obsessive-Compulsive Disorder Subgroups with Regard to Demographic and Phenomenological Characteristics Combining Multiple Correspondence and Latent Class Analysis

INTRODUCTION

Classic factor analysis of obsessive-compulsive disorder (OCD) dimensions and attempts to identify valid subgroups have not yet produced definitive conclusions.

OBJECTIVE AND METHODS

This study aims to examine possible homogeneous subgrouping of demographic and phenomenological characteristics in 134 treatment-seeking OCD patients. A combination of multiple correspondence analysis (MCA) and latent class analysis (LCA) was used.

RESULTS

MCA showed 2 distinct subgroups of OCD patients and LCA confirmed this result by a two-class solution. Both analyses demonstrated (a) a clear subgroup of female patients with washing compulsions, obsessions related to contamination, and late age of onset and (b) a subgroup comprised mostly of male patients with earlier onset of OCD, checking rituals, and doubts or aggressive obsessions. Mental, ordering, hoarding compulsions, religious, or sexual obsessions and images appeared exclusively in this subgroup.

CONCLUSIONS

Using 2 different analytic methods, we confirmed at least 2 subgroups in a clinical sample of Greek OCD patients. Future research combining dimensional and latent approaches could facilitate our understanding of the heterogeneous phenotype of OCD.

Dealing with Corona virus anxiety and OCD

The world is reeling under the crisis caused by corona virus disease (COVID-19), print, electronic and social media are flooded with numerous advisories issued by governments and other national & international agencies. While all this is being done with best of intentions so as to contain the spread of this viral disease, this is causing a significant negative impact on mental health of people specially person of obsessive-compulsive disorder with fear of contamination and excessive washing of hands.

Obsessive-Compulsive Disorder: A Review of the Cross-Cultural Epidemiological Literature

Early clinical studies suggested that obsessive-compulsive disorder (OCD) was a rare disorder, but recent large-scale epidemiological research conducted in North America using standardized diagnostic criteria (DSM-III) report prevalence rates between 1 to 3%. A review of clinical and case reports of OCD among psychiatric population in non-Western countries reveals similar sociodemographic and clinical correlates for the disorder compared to Western findings. Epidemiological studies using translated versions of standardized diagnostic instruments and conducted in non-Western countries, report similar prevalence rates and clinical phenomenology for O CD as that found in Western settings. Methodological and measurement issues relevant to conducting valid cross- cultural psychiatric research are discussed in relationship to the diagnosis of OCD. The review concludes that OCD is generally similar in prevalence, sociodemographic characteristics and clinical features in both Western and non-Western countries for adult populations.

Musical obsessions: a comprehensive review of neglected clinical phenomena

Intrusive musical imagery (IMI) consists of involuntarily recalled, short, looping fragments of melodies. Musical obsessions are distressing, impairing forms of IMI that merit investigation in their own right and, more generally, research into these phenomena may broaden our understanding of obsessive-compulsive disorder (OCD), which is phenomenologically and etiologically heterogeneous. We present the first comprehensive review of musical obsessions, based on the largest set of case descriptions ever assembled (N=96). Characteristics of musical obsessions are described and compared with normal IMI, musical hallucinations, and visual obsessional imagery. Assessment, differential diagnosis, comorbidity, etiologic hypotheses, and treatments are described. Musical obsessions may be under-diagnosed because they are not adequately assessed by current measures of OCD. Musical obsessions have been misdiagnosed as psychotic phenomena, which has led to ineffective treatment. Accurate diagnosis is important for appropriate treatment. Musical obsessions may respond to treatments that are not recommended for prototypic OCD symptoms.

Suicidal behaviour of Indian patients with obsessive compulsive disorder

BACKGROUND SETTING AND DESIGN

The chronicity, distress, high rates of comorbidity and varying degree of non response to treatment in Obsessive Compulsive Disorder (OCD) may contribute to suicidal behavior. There is relatively little information on suicidal behavior in OCD subjects. Our study design is Single point non-invasive, cross sectional, clinical study of new and follow up cases.

MATERIALS AND METHODS

Assessment of Suicidal Behavior in patients of OCD attending the adult Psychiatry O.P.D. of Chatrapati Shahuji Maharaj Medical University (CSMMU) U.P. Lucknow using (DSM-IV) criteria for diagnosis of Obsessive Compulsive Disorder, Structured Clinical Interview for DSM-IV Axis-I disorders, Yale Brown Obsessive Compulsive Rating Scale, Scale for Suicidal Ideation (SSI), Beck's Hopelessness Scale (BHS).

STATISTICAL ANALYSIS

Mean standard deviation and t test for independent samples, Pearson's correlation coefficient.

RESULTS

Statistically significant differences were seen in the SSI score between the "Clinical" and "Sub-Clinical" cases with Clinical group having higher scores. Value of correlation coefficient between YBOCS score and SSI and BHS score is positive and statistically significant (P<0.01).

CONCLUSION

"Clinical" group of patients had significantly higher scores of suicidal ideation measured by Scale of Suicidal Ideation (SSI). There was a significantly positive correlation between disease severity (YBOCS Score) and degree of suicidal ideation (SIS Score).

Musical obsessions

Obsessive-compulsive disorder (OCD) is a common psychiatric illness. A case of OCD is presented, in which the chief symptom was recurrent imagery of musical sounds of different instruments experienced by the person. Patient was a musician who played various musical instruments. Such obsessions with predominant musical themes, lyrics, and tunes have not been described in detail in standard textbooks of psychiatry or phenomenology, nor are they considered in the various diagnostic procedures for OCD. These symptoms are rare and may, at times, go unnoticed because of low clinical awareness.

Scrupulosity: a unique subtype of obsessive-compulsive disorder

The earliest descriptions of obsessive-compulsive disorder (OCD) were religious, as was the understanding of their origins. With the emancipation, religion in OCD was relegated to its status today: a less common symptom of OCD in most Western societies known as scrupulosity. The frequency of scrupulosity in OCD varies in the literature from 0% to 93% of cases, and this variability seems predicated on the importance of religious belief and observance in the community examined. Despite the similarities between religious ritual and compulsions, the evidence to date that religion increases the risk of the development of OCD is scarce. Scrupulosity is presented as a classic version of OCD, with obsessions and compulsions, distress, and diminished functioning similar to those of other forms of OCD. The differentiation between normal religiosity and scrupulosity is presented, and the unique aspects of cognitive-behavioral therapy in treating scrupulosity, especially in religious populations, are reviewed.

[Religious obsessions and religiosity]

OBJECTIVE

To assess the prevalence of religious obsessions in a general psychiatry setting, review sociodemographic and clinical characteristics of patients with religious obsessions, and explore the relation between these obsessions and religiosity.

METHOD

In a general psychiatry setting (n = 1500), we have studied patients with an obsessive–compulsive disorder (OCD), and then in this sample, we have identified those who also had religious obsessions.

RESULTS

OCD was found in 9.6% (n = 144) of patients. Religious obsessions are the most common and were found in 31.3% (n = 45) of patients in this group. Forty-five subjects (n = 45) with religious obsessions were compared with 99 subjects (n = 99) with other types of obsessions. The total number of obsessions is significantly higher in patients with religious obsessions. Patients with religious obsessions have a significantly higher score at the religiosity scale.

CONCLUSION

These results suggest that religious obsessions are common in patients with OCD, and that they are associated with religiosity.

An overview of Indian research in anxiety disorders

Anxiety is arguably an emotion that predates the evolution of man. Its ubiquity in humans, and its presence in a range of anxiety disorders, makes it an important clinical focus. Developments in nosology, epidemiology and psychobiology have led to significant advancement in our understanding of the anxiety disorders in recent years. Advances in pharmacotherapy and psychotherapy of these disorders have brought realistic hope for relief of symptoms and improvement in functioning to patients. Neurotic disorders are basically related to stress, reaction to stress (usually maladaptive) and individual proneness to anxiety. Interestingly, both stress and coping have a close association with socio-cultural factors. Culture can effect symptom presentation, explanation of the illness and help-seeking. Importance given to the symptoms and meaning assigned by the physician according to their cultural background also differs across culture. In this way culture can effect epidemiology, phenomenology as well as treatment outcome of psychiatric illness especially anxiety disorders. In this review an attempt has been made to discuss such differences, as well as to reflect the important areas in which Indian studies are lacking. An attempt has been made to include most Indian studies, especially those published in Indian Journal of Psychiatry.

An overview of Indian research in obsessive compulsive disorder

Obsessive-compulsive disorder (OCD) was considered a relatively rare disorder until about two decades ago. Since then, considerable advance has been made in understanding the various aspects of OCD that include epidemiology, clinical features, comorbidity, biology and treatment. In the last one decade, there has also been interest in a group of related disorders called obsessive-compulsive spectrum disorders. There is substantial research from India on various aspects of OCD, particularly from the National Institute of Mental Health and Neurosciences (NIMHANS), Bangalore. We attempt to review all the relevant Indian data on OCD.

Prevalence of obsessive-compulsive disorder in Turkish university students and assessment of associated factors

BACKGROUND

Many students who begin university at risky periods for OCD development cannot meet the new challenges successfully. They often seek help and apply to the university health center for psychiatric distress. We aimed to determine the prevalence and associated factors of Obsessive Compulsive Disorder (OCD) at students of the Cukurova University in this cross sectional study.

METHODS

This study was performed in the Cukurova University Faculty of Education with a population of 5500 students; the representative sample size for detecting the OCD prevalence was calculated to be 800. After collecting sociodemographic data, we questioned the students for associated factors of OCD. The General Health Questionnaire-12 (GHQ-12) and Composite International Diagnostic Interview (CIDI, Section K) were used for psychiatric evaluation. Logistic regression analysis was performed to evaluate the linkage between OCD and associated factors.

RESULTS

A total of 804 university students were included in this study. The GHQ-12-positive students (241 students, 29.9%) were interviewed using Section K of the CIDI (222 students, 27.6%). OCD was diagnosed in 33 (4.2%) students. The Logistic regression analysis of the data showed significant associations between OCD and male gender (p:0.036), living on government dormitory (p: 0.003), living on students' house/parental house (p:0.006), having private room in the parental house (p:0.055) and verbal abuse in the family (p:0.006).

CONCLUSION

This study demonstrates a higher prevalence of OCD among a group of university students compared to other prevalence studies of OCD in Turkish society. Furthermore, our findings also suggest relationships between OCD and sociodemographic factors, as well as other environmental stress factors.

Obsessive-Compulsive Hoarding: A Cognitive-Behavioural Approach

Obsessive-compulsive hoarding can be viewed within personality, neuroethological and cognitive-behavioural frameworks. Three cases of obsessive-compulsive hoarding are described in detail. All cases had some insight (albeit fluctuating) into their problem and were seeking treatment. There was evidence of abnormal risk assessment, fear of criticism, excessive guilt, overconscientiousness and inflated responsibility. Depression, emotional or material deprivation and significant loss during childhood and adolescence were experienced by all cases. The cases are considered to be consistent with a cognitive-behavioural model of obsessive-compulsive disorder emphasizing the importance of learning and cognition. Implications for treatment are discussed.

Sex differences in Indian patients with obsessive-compulsive disorder

Sex has been postulated as one of the factors mediating heterogeneity in obsessive-compulsive disorder (OCD). This study investigated the sex differences in OCD with respect to sociodemographics, symptom profile, and comorbidity including spectrum disorders. Two hundred thirty-one subjects diagnosed with OCD by Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria were included in the study. The subjects were evaluated by extensive clinical and semistructured interviews by expert clinical psychiatrists, and diagnosis was made by consensus. Male (n = 166) and female (n = 65) subjects with OCD were compared with respect to the data obtained. Males with OCD tended to have an earlier onset and had more symmetry/religious obsessions and miscellaneous compulsions. Males also showed a tendency to have attention deficit hyperactivity disorder. Female subjects were more likely to be married, have cleaning compulsions and be associated with trichotillomania. The findings support the hypothesis that there are sex differences in OCD, but the results are only partly comparable with other studies, suggesting that the phenotypic expression of OCD is possibly dependent on a complex interaction among biologic, personal, and cultural factors.

Obsessive-compulsive disorder with and without tic disorder: a comparative study from India

INTRODUCTION

Evidence from phenomenological, family, genetic, and treatment studies from Western centers have suggested that tic-related obsessive-compulsive disorder (OCD) could be different from non-tic-related OCD. This study from India investigated the differences in OCD with and without tics, with respect to sociodemographics, symptom profile, and comorbidity, including obsessive-compulsive spectrum disorders, to examine whether the clinical profile of tic-related OCD is similar to that reported previously.

METHODS

Fifty subjects with OCD and tics (chronic motor tics and Tourette syndrome) were compared with 141 OCD subjects without tics.

RESULTS

Subjects having OCD with tics tended to be males, and had an earlier onset of illness. They had more of symmetry/aggressive and religious obsessions, and cleaning, ordering/arranging, hoarding, and repeating compulsions and were associated with trichotillomania and hypochondraisis. Stepwise backward (Wald) regression analysis showed that an early age of onset, male gender, aggressive obsessions, cleaning compulsions, and trichotillomania were significantly associated with tic-related OCD.

CONCLUSION

The findings of this study from India are broadly similar to those reported previously from the West indicating the universality of differences in tic- and non-tic-related OCD. Our findings also support the existing evidence that tics contribute to the heterogeneity of OCD.

Obsessive-compulsive disorder: update on assessment and treatment

Obsessive-compulsive disorder (OCD) is a frequently debilitating and often severe anxiety disorder that affects approximately 2% of the population. This article discusses the presentation of the disorder and theories of etiology and provides an overview of assessment and treatment. A case description is included to illustrate the cognitive-behavioral assessment and treatment approach. OCD has similar prevalence rates cross-culturally around the world. Although its etiology is not established, neurobiological, genetic, cognitive, and behavioral factors have been implicated. The process of assessment for OCD plays an important role in establishing a therapeutic alliance with the patient and identifying treatment goals. The assessment of OCD can be guided by using published semi-structured interview tools, including a standardized symptom checklist and severity rating scale. Treatments that have shown efficacy for OCD are cognitive-behavioral therapy, including exposure and response prevention, and pharmacotherapy. However, up to 25% of patients fail to benefit from these evidence-based treatments. Other treatment approaches have recently been developed to further increase the effectiveness of cognitive-behavioral interventions. Strategies based on traditional cognitive approaches that challenge core beliefs have been shown to be effective. Acceptance-based therapies and treatments based on meta-cognitive principles have also shown promise and need further research.

Intrusive thoughts, obsessions, and appraisals in obsessive–compulsive disorder: A critical review

This article reviews empirical findings on two key premises of the appraisal model of obsessive-compulsive disorder (OCD): (a) non-clinical populations experience intrusive thoughts (ITs) that are similar in form and in content to obsessions; and (b) ITs develop into obsessions because they are appraised according to dysfunctional beliefs. There is support for the universality of ITs. However, the samples used are not representative of the general population. IT measures do not relate systematically or exclusively to OCD symptom measures, and are not specific enough to exclude other types of intrusive thoughts such as negative automatic thoughts or worries, nor are they representative of all types of obsessions. When general distress is controlled, there is so far no evidence that participants with OCD endorse obsessive belief domains more strongly than anxious participants, and inconclusive evidence that OCD and non-clinical samples differ on the belief domains. Some OCD symptom subtypes are associated with belief domains. Currently, there is no coherent model to offer strong predictions about the specificity of the empirically derived belief domains in OCD symptom subtypes. Cognitive therapy based on the appraisal model is an effective treatment for OCD, although it does not add to the treatment efficacy of behaviour therapy. It is unclear how appraisals turn ITs into obsessions. Implications for future research are discussed.

Scrupulosity in patients with obsessive-compulsive disorder: relationship to clinical and cognitive phenomena

Scrupulosity is often encountered among individuals with obsessive-compulsive disorder (OCD), yet relatively few studies have examined this particular symptom presentation. Using a large sample of OCD patients, the present investigation examined (a) the relationship between religiosity and scrupulosity, (b) the association between scrupulosity and the severity of OCD, anxiety, and depressive symptoms, and (c) the connection between scrupulosity and cognitive domains related to OCD. Scrupulosity was correlated with obsessional symptoms and several cognitive domains of OCD, including beliefs about the importance of, and need to control intrusive thoughts, an inflated sense of responsibility, and moral thought-action fusion. These results are examined in terms of cognitive behavioral conceptualizations of OCD and the treatment implications of these findings are discussed.

Obsession in the strict sense: A helpful psychopathological phenomenon in the differential diagnosis between obsessive-compulsive disorder and schizophrenia

The paper presented follows the hypothesis that differentiation between obsessive-compulsive disorder and schizophrenia is possible only by focusing on the single phenomenon of obsession. The statement of a nosological specificity of obsession, called obsession in the strict sense, is set against the current views of ICD-10 and DSM-IV of obsession as a ubiquitous, non-specific phenomenon appearing in comorbidities. In the succession of the paper, the historical development of these two very different views and their clinically mixing is reconstructed. The phenomenological clarification of the structure of the obsessive phenomena leads to the term of obsession in the strict sense. The distinction between obsessive-compulsive disorder and schizophrenia can take place at the psychopathological interface between obsession in the strict sense and delusional idea. The examination of the literature on the connection between obsessive-compulsive disorder and schizophrenia shows that there is no definitive connection between obsession in the strict sense and schizophrenia. Finally, some case reports are presented to sharpen clinical suspicion for other possibly wrong diagnoses.

Obsessive-compulsive disorder: a 3-year prospective follow-up study of patients treated with serotonin reuptake inhibitors OCD follow-up study

This study aimed to evaluate the long-term course of obsessive-compulsive disorder (OCD) in patients treated with serotonin reuptake inhibitors (SRIs) and to identify predictors of clinical outcome. Seventy-nine patients fulfilling DSM-IV criteria for OCD were followed prospectively for 3 years. Baseline information was collected on demographic and clinical characteristics, using standardized instruments. During the follow-up period, the clinical status of each patient was evaluated monthly in the first year and bimonthly thereafter by means of the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) and the Hamilton Rating Scale for Depression (HDRS). The cumulative probability of achieving at least partial remission from obsessive-compulsive (OC) symptoms during the 3-year period was 65%. The probability of full remission was 38%. For subjects who achieved at least partial remission, the probability of subsequent relapse was 60%. Significant predictors of poor outcome included a longer duration of illness, a greater severity of OC symptoms at intake, and the presence of comorbid schizotypal personality disorder. The findings confirm that the course of illness in OCD is usually continuous with fluctuations in the intensity of OC symptoms. Despite adequate SRI therapy, relatively few patients achieve a completely asymptomatic state, and of those who achieve at least a partial remission, a substantial proportion subsequently relapse. One third of OCD patients is treatment-resistant. Further studies with large samples are required to adequately identify predictors of long-term outcome of OCD in order to optimize the choice among the existing treatment modalities. The development of alternative strategies is needed to improve the treatment approaches for treatment-resistant OCD patients.

Why are some obsessions more upsetting than others?

Little is known about why certain obsessional thoughts are more upsetting than others for people with obsessive compulsive disorder (OCD). Obsessional thought content often seems arbitrary to sufferers. The current study examined three possible reasons why particular thoughts would be especially upsetting for individuals, based on suggestions put forth by cognitive theories of obsessional thoughts. Twenty-eight individuals with a principal diagnosis of OCD completed questionnaires and interviews at two different periods of time on (1) their most upsetting current obsession and (2) their least upsetting current obsession. Results suggested that more upsetting obsessions were evaluated as more meaningful or significant than less upsetting obsessions, and more upsetting obsessions contradicted valued aspects of the self to a greater degree. All examples of current obsessions, both most and least upsetting, arose in the context of life concerns or issues. Results support cognitive theories in that the strength and nature of appraisal appears to be linked with the distress associated with a thought, and more upsetting thoughts are those that have implications for a person's sense of self.

Epidemiology and phenomenology of obsessive-compulsive disorder in non-referred young adolescents: a Polish perspective

OBJECTIVE

The aim of this study was to investigate the frequency and phenomenology of obsessive-compulsive disorder (OCD) and subclinical OCD in a non-referred population of young Polish adolescents.

METHOD

A two stage ascertainment procedure (school screening and diagnostic evaluation) was used to identify affected individuals. In the first stage, 3,100 pupils were asked to complete the Polish version of the 20-item Leyton Obsessional Inventory-Child Version (LOI-CV). In the diagnostic stage, the presence of obsessions and compulsions was assessed with the author's structured interview questionnaire based on DSM-IV and ICD-10 diagnostic criteria for OCD; the Polish version of the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) was used to rate the symptom severity.

RESULTS

A frequency of 0.38 % was found for OCD and 2.7 % for subclinical OCD. There was no significant difference in the phenomenology, demographic characteristic or socio-familial variables comparing the diagnosed OCD and subclinical OCD subjects.

CONCLUSIONS

The identified OCD cases had characteristics similar to those of previously described clinical and non-referred samples.

Symptoms of obsessive-compulsive disorder in a sample of Iranian patients

BACKGROUND

Characteristic features of the obsessive-compulsive disorder (OCD) occur with remarkable consistency in different cultural settings. The content of symptoms, however, seems to vary across cultures.

AIMS

To examine the content of symptoms in a sample of OCD patients from Iran.

METHODS

In a sample of 135 patients recruited from three treatment settings the prevalence of symptoms with different contents were ranked and compared across genders.

RESULTS

Doubts and indecisiveness were the most common obsessions and washing the most common compulsion for the whole sample. Fears of impurity and contamination, obsessive thoughts about self-impurity and washing compulsions were more common in women, whereas blasphemous thoughts and orderliness compulsions were more common in men.

CONCLUSIONS

With minor differences, the pattern of symptoms with various contents in this sample was similar to that in Western settings.

Phenomenology of obsessive-compulsive disorder in Taiwan

This study was designed to assess the phenomenology, comorbidities, correlation with depressive disorders, and gender differences in obsessive-compulsive disorder (OCD) in Taiwan. Two hundred outpatients who fulfilled the diagnostic criteria of OCD according to DSM-IV were included. Patient characteristics, age at onset, symptom profile, and Axis I comorbidity were recorded. Gender differences, age at onset, and comorbidity of depressive disorders among different subtypes of OCD were compared. The most common obsession was contamination, followed by pathological doubt, and need for symmetry. The most common compulsion was checking, followed by washing, and orderliness compulsions. More men than women presented with the obsession of need for symmetry. Eighty-three (41.5%) subjects had comorbid depressive disorders. Women had more major depressive disorder. Patients with somatic obsessions were more likely to have major depressive disorder. Most clinical characteristics of OCD in Taiwan were similar to that of previous studies in other countries.

Religiosity and religious obsessions in obsessive-compulsive disorder

Religion has often been thought to play a part in the genesis of some cases of obsessive-compulsive disorder (OCD). In this study, we explored the relationship between religiosity, religious obsessions, and other clinical characteristics of OCD. Forty-five outpatients with OCD were evaluated with the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) and the Yale-Brown Obsessive-Compulsive Checklist (Y-BOCC) as well as the Religious Practices Index (RPI), which was developed for this study. On the basis of these evaluations, 42% of the patients were found to have religious obsessions. Despite differences in the frequency of religious obsessions found in this study compared with others, a factor analysis revealed the symptom dimensions to be similar to those found in other OCD samples. There was no significant difference in the overall severity of obsessions and compulsions between patients with and without religious obsessions. RPI scores did not differ significantly between groups. We failed to find a relationship between RPI scores or religious obsessions and any particular type of obsession or compulsion. A logistic regression analysis revealed that the sole predictor of the presence of religious obsessions was a higher number of types of obsessions. In conclusion, we failed to find a conclusive relationship between religiosity and any other clinical feature of OCD, including the presence of religious obsessions. On the other hand, we showed that the patients who tend to have a variety of obsessions are more likely also to have religious obsessions. Thus, religion appears to be one more arena where OCD expresses itself, rather than being a determinant of the disorder.

Personality disorders

Some general recommendations can be made, collected from these subjective descriptions of personality types. Because determining an accurate psychiatric diagnosis is not the internist's aim, it is better for him or her to have a stance that generalizes to all patients, which can be refined as personality characteristics emerge. Tolerate the patient's affect (such as anger or anxiety), being firm and kind, rather than punitive or overinvested. Accept dependency and vulnerability. Accept and respect the underlying coping style. Understand that the patient's personality style is the best (and usually only) way he or she knows to have a relationship, including a relationship with the physician. Understand that personality traits additionally may have a function (e.g., to guard against anxiety or depression). Recognize that personality traits do not come in pure form. One personality trait is likely to blend into or overlap with other traits. Identify and treat any underlying symptom disorder, such as anxiety, depression, irritability, or thought disorder. Educate the patient clearly (and without patronizing) about medical illness. Document what was explained to the patient and how the patient responded, including dispassionate observations about behavior and emotional expression. Appreciate the patient's possible attachment to medical symptoms. Avoid arguments with patients who make unreasonable demands. Make timely judgments about whether or not to accede to a demand. When in doubt about a patient's honesty, give the patient the benefit of the doubt. Do not worry about being used because all patients use their physicians to some extent. Go to the limits of your tolerance for a patient's personality, but know your limits and refer to a colleague when you cannot work with the patient. Terminate an interaction and get help if there is a risk (or fear) of violence. Given the time it takes to manage the relationship and the psychiatric elements of treatment, a referral to a psychiatrist or other mental health professional often is wise if the patient will accept it. Include the mental health professional as part of the medical team. Although these various recommendations have been emphasized in connection with certain personality types, one can be flexible about their application in a variety of patients. It is important also to reiterate the limits of subjective descriptions. It is rare to find any of the aforementioned subjective descriptions in unmodified form; characteristics of more than one personality type usually appear in the same person. The descriptions are composites that provide a starting point for the physician. The physician should edit the composites based on experience with real patients. This article has described human characteristics and rough guidelines for helpful human responses and possible pharmacologic interventions. So equipped, the primary care physician may find it less troubling and more interesting to face the wide variation in human character.

Evidence of a schizotypy subtype in OCD

OCD patients represent a heterogeneous mix of clinical phenotypes, likely reflecting a wide range of genetic vulnerabilities. In other medical illnesses, neurobiologically-based traits with a genetic component that are associated with the target disorder have been successfully used to detect patients with a specific genetic liability to disease. The overlap between symptoms of OCD and Schizophrenia suggested that schizotypal traits could have the potential to distinguish a relatively homogeneous subtype of OCD. We obtained schizotypy scores for 119 affected adult probands who met lifetime criteria for DSM-IV OCD. Five subscales from the Structured Interview of Schizotypy were used to assess ideas of reference, suspiciousness, magical thinking, illusions and psychotic-like thought. Selected for their obvious face validity with the cardinal signs of schizophrenia, Cronbach's alpha suggested that these subscales also provided a reliable measure of positive sign schizotypy (0.83). Fifty percent of our OCD sample had mild to severe positive schizotypy signs. t- and chi2 tests of significance suggested seven variables that distinguished OCD patients with schizotypy, including earlier age of onset, greater number of comorbid diagnoses and increased rates of learning disability, aggressive and somatic obsessions and counting and arranging compulsions. Three of these seven variables, including learning disabilities, counting compulsions and history of specific phobia, significantly increased the odds of schizotypy among patients with lifetime OCD. These findings enhanced the validity of the schizotypy construct in OCD. Whether this schizotypy subtype can distinguish a subgroup of patients with relatively homogeneous genetic characteristics waits further investigation.

Phenotypic characteristics of Obsessive-Compulsive Disorder ascertained in adulthood

Over the past decade, the increased awareness and knowledge of Obsessive-Compulsive Disorder (OCD) has allowed the in-depth study of its phenotypic characteristics. The largest studies to date have described the symptom and syndrome characteristics of treatment-seeking patients. While usefully homogeneous with regard to their current state, the clinical characteristics of patients seeking treatment may only partially represent the OCD population. We report findings from 100 self-selected volunteers at various stages of their OCD illness who were participating in a genetic study. Many similarities with past reports were found, including high rates of mood disorder, significantly more mood disorder in females as compared with males, and increased social impairment among males despite an equal amount of time in episodes of disorder. On the other hand, mean age of onset in this nontreatment seeking population was younger. Lifetime rates of obsessions and compulsions in this population were substantially higher than previous reports, suggesting that the content of obsessions and compulsions shifted over time, and evolved into a lifetime repertoire. Furthermore, a separate analysis of the age of clinically significant O-C symptom onset without impairment revealed that males and females did not differ, suggesting that previous reports of earlier onset age in males may actually reflect earlier onset of impairment. Future genetic studies may benefit from the analysis of both significant O-C symptom onset, as well as the onset of full-syndromal OCD. These findings may suggest phenotypic characteristics that define homogeneous subgroups of patients with OCD.

OCD in Bahrain: a phenomenological profile

Fifty patients with a primary diagnosis of Obsessive-Compulsive Disorder (OCD) were studied during the course of the year 1994 from a phenomenological point of view in order to delineate the various forms and contents of obsessions and compulsions. An attempt was made to highlight the frequency with which the different forms and contents occur. Six types of obsessions were identified: doubts, thoughts, fear (phobia), images, impulses and miscellaneous. Compulsive acts were classified into two types: yielding and controlling. The contents of obsessions could be classified into eight broad categories as relating to: dirt and contamination, germs, aggression, sex, religion, blasphemy, illness and indecisiveness. Thirty eight percent of the patients displayed obsessional thoughts related to dirt and contamination, while forty per cent showed religious and blasphemous obsessional thoughts and doubts. Fifty six percent of the patients had compulsions of which 36% were multiple, while 20% displayed only a single compulsion. The paper discusses these findings and emphasizes the role played by sociocultural and religious factors in shaping the character of an obsessional thought content.

Attentional bias in obsessional compulsive disorder

To date, studies of information processing in anxiety disorders have suggested that the latter are characterised by vigilance for threatening stimuli, possibly specific to personally relevant threat content. The present study represents an attempt to establish whether patients suffering from Obsessional Compulsive Disorder (OCD), generally classified as an anxiety disorder, show a similar cognitive bias. Thus, a replication of MacLeod, Mathews and Tata's (1986) study [Journal of Abnormal Psychology, 95, 15-20] is reported, employing modified materials of direct concern to the OCD subjects i.e. Contamination-related words. The results did indeed reveal content specific vigilance, whereby the OCD group were more vigilant for contamination content than mood-matched High Trait Anxious (HTA) controls, but the reverse was true for Social Anxiety words. Additionally, while a general threat interference effect was identified for both OCD and HTA subjects this was not content specific. A second experiment employing Low Trait Anxious subjects revealed no vigilance for threat nor any threat interference in this sample. The clinical implications and possible mechanism underlying these results are discussed.

Predictors of treatment outcome in the behavioural treatment of obsessive-compulsive disorder

BACKGROUND

An investigation to determine which prognostic variables are associated with behavioural treatment failure in obsessive-compulsive disorder (OCD). Empirically established prognostic variables measured at the start of treatment may lead to adjusted treatment programmes for these patients.

METHOD

Forty patients, diagnosed with OCD, received a standardised treatment consisting of 18 sessions in vivo exposure and response prevention. Compulsive behaviour (MOCI) and obsessive fear (ADS) were the outcome measures. Prognostic variables included were initial severity of OC complaints, initial level of depression, problem duration, patients' motivation for treatment, quality of the therapeutic relationship, and marital dissatisfaction.

RESULTS

Greater initial severity of complaints (P < 0.01), and depression (P = 0.03) predicted poorer outcome for compulsive behaviour. Greater initial severity of complaints (P < 0.01), and the conjoint variables higher level of depression, longer problem duration, poorer motivation for treatment, and dissatisfaction with the therapeutic relationship predicted poorer outcome for obsessive fear (P < 0.01).

CONCLUSIONS

The complaint-related variables of initial severity, initial depression, and problem duration, and the non-specific treatment variables of patients' motivation and quality of the therapeutic relationship, affect behavioural treatment outcome in OCD.

Dental management of the patient with obsessive-compulsive disorder

Individuals with obsessive-compulsive disorder frequently manifest bizarre behaviors that contribute to the oral disease development. The medications used to manage the disorder can cause profound xerostomia and compound the magnitude of oral pathology. The patient's behavioral alterations and drug therapy might require dental treatment modifications.

Pattern of obsessive-compulsive disorder in eastern Saudi Arabia

In 32 Muslim Saudis with obsessive-compulsive disorder, compulsive acts (78%) and doubts (66%) were the commonest forms. Religious themes predominated in both the obsessions and compulsions.

Dimensional approach to obsessive-compulsive disorder in childhood and adolescence

Based on a review of the charts of child and adolescent psychiatric patients, a group of patients with obsessive-compulsive symptoms and a control group were identified. Obsessive-compulsive symptoms described in the charts were classified according to form using the checklist of Khanna et al. By use of latent trait models, a 6-item obsessive-compulsive rating scale was established revealing a dimensional rather than a categorical distribution of obsessive-compulsive symptoms. The correlation with other clinical features was investigated.

Gender-divergent aetiological factors in obsessive-compulsive disorder

Among 307 adults with OCD, early onset (age 5-15 years) was more common in men and later onset (age 26-35 years) in women. Early onset was associated with more checking, and late onset with more washing. More women than men had a history of treated depression; 12% of the women but none of the men had a history of anorexia. More women than men were married. Gender-divergent features may reflect differential aetiological factors. Our sample resembled others in the literature in its slight overall female preponderance, low rate of marriage and low fertility, onset mainly before age 35 years, chronicity, and common present and past depression.

Clusters of obsessive-compulsive phenomena in obsessive-compulsive disorder

Clusters of phenomena were obtained by two clustering techniques, using the form and content of obsessions and compulsions. Significant clusters which emerged involved washing, checking, thoughts of past, and embarrassing behaviour. Depression occurred as a discrete cluster. Eighty-nine per cent of subjects could be fitted into at least one cluster; over half could be fitted into only one cluster. Washers and checkers made up more than half of the sample studied.
