Involuntary social cue integration in patients with obsessive compulsive disorder.

OBJECTIVE: Patients with obsessive compulsive disorder (OCD) have inferior social functioning compared to healthy controls, but the exact nature of these social deficits, and the underpinning mechanisms, are unknown. We sought to investigate social functioning in patients with OCD by measuring their involuntary/spontaneous processing of social cues using a specifically designed test, which might reveal deficits in these patients that explicit voluntary tasks do not detect. METHODS: The sample of the study consisted of an OCD group (n = 25) and a control group (n = 26). Both groups performed an adaptation of the Social Distance Judgment Task (SDJT; Jellema et al., 2009), in which participants have to judge the geometrical distance between two human cartoon figures presented on a computer screen. Head/gaze direction and body direction were manipulated to be either compatible, i.e. both directed to the left or to the right (Compatible condition) or incompatible, i.e. body directed toward the observer (frontal view) and head/gaze directed to the left or right (Incompatible condition). RESULTS: In the Compatible condition, controls nor OCD patients were influenced by the social cues in their judgments of the geometrical distances. However, in the Incompatible condition, where the attentional cue was more conspicuous, both groups were influenced by the cues, but the controls to a significantly larger extent than the OCD patients. CONCLUSIONS: This study showed that patients with OCD are less likely, compared to controls, to automatically/spontaneously integrate the other's direction of attention into their visual percept. This may have resulted in their judgments of the geometrical distances between the agents to be more accurate than those of controls. The suggested impairment in automatically integrating social cues may have important repercussions for the social functioning of OCD patients.

Association Between Mood Disorder Severity, Treatment Response and Systemic Inflammatory Markers: Exploring the Role of NLR, PLR, MLR, and SII.

Background: In this study, the relationship between treatment response, clinical features of episodes such as psychosis, suicidal behavior, and agitation, duration of hospitalization, and systemic inflammation markers Systemic Inflammatory Index (SII), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR) in bipolar affective disorder manic episode (BAD-M), bipolar affective disorder-depressive episode (BAD-D), and major depressive disorder (MDD) were investigated. Methods: TheNLR, MLR, PLR, and log SII were measured using parameters from a complete blood count. Admission and discharge Young Mania Rating Scale and Hamilton Depression Rating Scale scores were evaluated. This is a retrospective study conducted with a total of 451 inpatients, 122 (27.10%) of whom were diagnosed with BAD-M, 60 (13.20%) with BAD-D, and 269 (56.60%) with MDD. Results: The patients with manic episodes have higher levels of NLR (P = .019), MLR (P = .002), and log SII (P = .007). In the bipolar depression and mania groups, the patients with and without treatment responses did not differ in terms of inflammation markers; the log PLR value was found to be higher in the unipolar depression group in the patients who did not reach remission (P = .048). Conclusion: This study reveals associations between inflammation markers and different types of mood episodes. Higher NLR, MLR, and log SII levels in bipolar mania and lower NLR levels in agitated unipolar depression provide clues about changes in inflammation across different episodes. Studies with larger samples are needed to evaluate the relationship between inflammatory markers, the severity of mania and depression, and the response to treatment.

The Relationship between COVID-19 Protection Behaviors and Pandemic-Related Knowledge, Perceptions, Worry Content, and Public Trust in a Turkish Sample.

Background: This study aimed to explore the effect of knowledge, COVID-19-related perceptions, and public trust on protective behaviors in Turkish people. Methods: Data were collected from an online survey (Turkish COVID-19 Snapshot Monitoring) conducted between July 2020 and January 2021. The recommended protective behaviors (hand cleaning, wearing a face mask, and physical distancing) to prevent COVID-19 were examined. The impacts of the following variables on protective behaviors were investigated using logistic regression analysis: knowledge, cognitive and affective risk perception, pandemic-related worry content, public trust, conspiracy thinking, and COVID-19 vaccine willingness. Results: Out of a total of 4210 adult respondents, 13.8% reported nonadherence to protection behavior, and 86.2% reported full adherence. Males and young (aged 18−30 years) people tend to show less adherence. Perceived self-efficacy, susceptibility, and correct knowledge were positively related to more adherence to protective behavior. Perceptual and emotional factors explaining protective behavior were perceived proximity, stress level, and worrying about the relatives who depended on them. Trust in health professionals and vaccine willingness were positive predictors, while conspiracy thinking and acquiring less information (<2, daily) were negative predictors. Unexpectedly, trust in the Ministry of Health showed a weak but negative association with protection behavior. Conclusions: Perceived stress, altruistic worries, and public trust seem to shape protection behaviors in addition to individuals' knowledge and cognitive risk perception in respondents. Males and young people may have a greater risk for nonadherence. Reliable, transparent, and culture-specific health communication that considers these issues is required.

Schizophrenia with obsessive-compulsive disorder and obsessive-compulsive disorder with poor insight: a neuropsychological comparison.

Schizophrenia patients with obsessive-compulsive disorder (OCD) may be a subgroup of schizophrenia, and OCD patients with poor insight may show psychotic-like symptoms. The aim of this work is to compare the neuropsychological performance of those patients with schizophrenic patients who do not have OCD symptoms and with OCD patients who have good insight. The sample consisted of 89 patients (16 OCD-schizophrenic patients, 30 non-OCD schizophrenic patients, 30 OCD patients with good insight, 13 OCD patients with poor insight). Neuropsychological evaluation included executive functions, verbal and visual memory and attention tasks. While schizophrenic patients with OCD did not differ from the non-OCD schizophrenia and OCD with poor insight groups on long-term visual and verbal memory performance, they showed poorer performance than the OCD group on long-term visual and verbal memory tests. Considering executive function, the OCD group with poor insight performed significantly worse than their counterparts with good insight, and the latter group performed better than the schizophrenia patients. The results of this study suggest that the neuropsychological performance of schizophrenia patients with OCD did not differ from that of non-OCD schizophrenic patients, and that OCD patients with poor insight were more likely to share similar cognitive characteristics with the schizophrenia groups. Our results also provide neuropsychological support for the hypothesis that OCD and schizophrenia may be a spectrum disorders.

Characteristics of suicidal behavior in a Turkish sample.

BACKGROUND: Suicidal behavior is one of the most important problems in psychiatric clinics. Several sociodemographic and clinical characteristics may have different effects on suicidal behavior. AIMS: To examine the sociodemographic and clinical characteristics of a sample of 144 suicide attempters admitted to a Turkish emergency clinic for a suicide attempt. METHODS: All subjects were interviewed by a consultant psychiatrist. For all individuals, data on DSM-IV psychiatric diagnoses, sociodemographic data, Beck's Hopelessness Scale (BHS), Becks's Suicidal Ideation Scale (SIS), and Beck's Suicidal Intention Scale (BSIS) were collected. RESULTS: The majority of suicide attempters were females characterized by low educational status and low religious orientation. Drug overdose was the most common method of suicide attempt and conflict within the family was the most frequent psychological stress factor. Three-quarters of attempters (74.6%) met DSM-IV criteria for at least one psychiatric diagnosis. Of these, 28.5% met criteria for major depressive disorder. Suicide attempters with depression tended to be immigrant, urban dwellers with high scores on the suicide intent scale. CONCLUSIONS: In the present study, the findings are useful in showing the risk factors related to suicidal behavior.

Metacognitive Beliefs and Their Relation with Symptoms in Obsessive-Compulsive Disorder.

INTRODUCTION: Metacognitive constructs have shown promise in explaining the symptoms of Obsessive-Compulsive Disorder (OCD). Few studies have examined the role of metacognitions in symptom dimensions of OCD, despite mounting clinical, neuropsychological and imaging evidence for the distinctiveness of these dimensions. METHODS: Metacognitions were assessed using the Metacognitions Questionnaire (MCQ-30) in 51 participants with DSM IV OCD and 46 healthy controls. The Maudsley Obsessional Compulsive Inventory (MOCI) was used to quantify symptom dimensions, along with the Hamilton Anxiety Rating Scale (HAM-A) for anxiety, and Hamilton Depression Rating Scale (HAM-D) for depression. RESULTS: Individuals with OCD differed from healthy controls on beliefs of uncontrollability and danger when depression and anxiety were controlled for. Correlations between metacognitive beliefs and obsessive-compulsive symptom dimensions were largely similar across the OCD and healthy control groups. Hierarchical regression showed that need to control thoughts contributed to checking, cleaning and rumination symptoms; cognitive self-consciousness to symptoms of slowness; uncontrollability and danger to doubt symptoms; positive beliefs to checking symptoms. CONCLUSIONS: Specific associations between metacognitive variables and the different symptom dimensions of OCD are evident, however, severity of anxiety and depression also contribute to these associations.

Cognitive functions in euthymic patients with bipolar disorder.

BACKGROUND: Recent studies have focused on the nature of cognitive dysfunction in bipolar patients. The purpose of the current study was to investigate cognitive performance of individuals with bipolar disorder compared to healthy control subjects during a well-established euthymic period. METHODS: The sample consisted of 27 bipolar euthymic patients and 21 control subjects. Verbal and visual memory performance, attention, executive functions and psychosocial functions were evaluated for each participant. RESULTS: Bipolar patients showed significant attentional deficit and executive dysfunction and also poor performance on verbal and visual memory tasks compared to the controls. Illness duration and lifetime total episode number and previous episode with psychotic features was associated with worsened performance on attention, executive and memory tasks. Psychosocial functioning was not associated with cognitive deficit. CONCLUSIONS: The present study showed persistent cognitive impairment on inhibitory control and selective attention as well as poor performance on verbal and visual memory tests in a group of bipolar euthymic patients. The impaired neuropsychological performance was associated with duration of illness, total number of episodes per lifetime, and previous episodes with psychotic features. Attentional dysfunction seemed to be a trait abnormality for the sample studied.

Relationship between Serum Bilirubin Levels and Metabolic Syndrome in Patients with Schizophrenia Spectrum Disorders.

OBJECTIVE: We investigated the relationship between serum bilirubin levels and metabolic syndrome (MetS), and the longitudinal effects of baseline serum bilirubin concentrations on MetS in patients with schizophrenia spectrum disorders undergoing atypical antipsychotics. METHODS: The sample of this study consisted of 131 patients with schizophrenia spectrum disorders. Waist circumference, blood pressure, and levels of triglycerides, high-density lipoprotein cholesterol, fasting glucose, and insulin were evaluated at baseline and at month six. Serum bilirubin levels were measured at baseline. Serum bilirubin levels of the patients with and without MetS criteria were compared. We also compared patients with high and low bilirubin levels (upper and lower 50th percentiles of serum bilirubin levels) in terms of MetS criteria, MetS frequency, and course of MetS. RESULTS: Serum direct bilirubin levels were more consistently related to MetS and MetS-related variables. The waist circumference and triglyceride criteria for MetS were significantly related to low serum direct bilirubin at baseline; waist circumference and fasting glucose criteria, and insulin resistance were associated with low serum direct bilirubin at follow-up. MetS diagnosis and the presence of the waist circumference criterion were more frequent at the baseline and the follow-up in low bilirubin group. At the end of the follow-up period, the rate of reverse MetS was significantly higher in the high bilirubin group. CONCLUSION: Our results have suggested that serum direct bilirubin levels showed a more reliable and stable relationship with abdominal obesity for MetS components.in patients with schizophrenia spectrum disorders using antipsychotics. Further studies are required.

Relationship between Obsessive Beliefs and Symptoms in Patients with Obsessive Compulsive Disorder.

INTRODUCTION: Misinterpretation of intrusive thoughts because of obsessive beliefs has been thought to be important in the development of obsessive compulsive symptoms. In current study, (I) the difference between OCD patients and healthy controls in regard of obsessive beliefs and (II) the relation of obsesive beliefs with the prevelance and severity of obsessive compulsive symptoms was investigated. METHODS: The current study included 47 OCD patients and 44 healthy controls who have same properties with regard to age, sex and duration of education. All subjects were applied to Obsessive Beliefs Scale, Maudsley Obsessive Compulsive Scale, Hamilton Depression Rating Scale and Hamilton Anxiety Rating Scale. OCD patients were applied to Yale Brown Obsessive Compulsive Scale as well as the other scales. RESULTS: In analyses by controlling depression and anxiety scores, OCD patients had significantly higher scores than controls, with regard to all subscales of Obsessive Beliefs Scale. Also, prevalence of obsessive compulsive symptoms other than cleaning were correlated with obsessive beliefs about "responsibility and threat estimation" and "perfectionism and need for certainty". Hovewer, there was no correlation in between severity of obsessive compulsive symptoms and subscale scores of Obsessive Beliefs Scale. CONCLUSION: Excluding the effects of depression and anxiety, generally the results suggests that obsessive beliefs have an important role for development of obsessive compulsive symptoms. Future studies of seperated OCD subgroup with regard to obsessive compulsive symptoms will be helpful in determinig the difference among these subgroups in regard of obsessive beliefs.

[Reliability and validity of the Cornell Scale for Depression in Dementia in an elderly Turkish population]. / Cornell Demansta Depresyon Olçegi'nin Türk yasli toplumunda geçerlik ve güvenilirligi.

OBJECTIVE: The reliability and validity of the Cornell Scale for Depression in Dementia were investigated in a Turkish population over 60 years of age. METHOD: Forty-six male and 34 female demented elderly people classified as demented according to DSM-IV criteria were included in the study. The Structured Clinical Interview for DSM-IV Clinical Version (SCID-I) was completed for all subjects to establish the diagnosis of major depression. The Cornell Scale for Depression in Dementia (CSDD), Geriatric Depression Scale (GDS), Mini Mental State Examination (MMSE) and Global Deterioration Scale (GDS) were used. RESULTS: A high test-retest correlation level (r: 0.93) was obtained for the total scores of the scale. The scale also showed high internal consistency (a: 0.86). The validity analysis of the scale resulted in a significant difference (p<0.001) between the total scores of the group with dementia and depression and the group with dementia but without depression. Two items (9-19) showed a low correlation (r<.30) in the test-retest analysis. On the other hand, two items (6-19) had a low item-total score correlation (r<.30). CONCLUSIONS: The results indicated that the scale is reliable and valid for diagnosing depression in dementia in an elderly Turkish population. We expect that the Cornell Scale for Depression in Dementia will be a useful instrument in pharmacological investigations and in studies of the phenomenology and course of depressive symptoms in demented patients.

[Psychiatric disorders in cancer patients and associated factors]. / Kanser hastalarinda psikiyatrik bozukluklar ve iliskili etmenler.

OBJECTIVE: There is a high prevalence of psychiatric disorders, especially depression and anxiety, among cancer patients. If they are left untreated, especially depressive disorders, they may result in poor treatment compliance, increased hospital stays and reduced quality of life. The aim of this prospective study is to investigate the prevalence of psychiatric morbidity among cancer patients and the factors that predict psychiatric morbidity. METHOD: One hundred and fifty patients with the diagnosis of cancer who were treated in different departments of the Pamukkale University Hospital were included in this study. Psychiatric diagnoses were made according to the criteria of DSM-IV with the SCID-I interview. In addition, all patients were evaluated using the General Health Questionnaire (GHQ) and the Hospital and Anxiety Depression Scale (HADS). RESULTS: 28.7% of cancer patients were found to have a DSM-IV Axis I diagnosis. The most common diagnoses were adjustment disorder with depressed mood (14%) and major depressive disorder (11.3%). Female gender, awareness of the diagnosis of cancer, history of previous premorbid psychiatric disorders and stress factors were correlated with psychiatric morbidity. CONCLUSION: In this study, the most common diagnoses were adjustment disorder with depressed mood and major depressive disorder, suicidal ideations were also frequently found. Awareness of the nature of the illness, female gender and the duration of the illness were the parameters which predicted psychiatric morbidity. Careful attention should be paid to cancer patients in order to diagnose and treat their psychiatric disorders. Furthermore, two screening instruments (GHQ and HADS) performed satisfactorily for screening of psychiatric disorders in cancer patients.

Manic episode following deep brain stimulation of the subthalamic nucleus for Parkinson's disease: a case report.

AIM: Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is an established therapy for patients with Parkinson's disease (PD) associated with motor complications of long term L-dopa treatment. MATERIAL AND METHODS: Here we report two cases with DBS- induced manic episode, focusing on the functional and anatomic correlates of psychiatric adverse effects of STN stimulation. RESULTS: We present two cases of PD with motor complications due to long term L-dopa treatment that developed their first episodes of mania with psychotic symptoms after bilateral STN-DBS implantation. DBS-induced psychiatric adverse effects may be attributable either to limbic connections and STN-specific oscillations or stimulation of the medial forebrain bundle.

[Prefrontal cortex neurochemical metabolite levels in major depression and the effects of treatment: an HMRS study]. / Major depresyonda prefrontal korteks nörokimyasal metabolit düzeyleri ve sagaltimin etkileri: bir HMRS çalismasi.

OBJECTIVE: Neuronal degeneration in the prefrontal cortex during depression results in altered production of neurochemical metabolites. The aim of the present study is to examine changes in neurochemical metabolites in the prefrontal cortex and evaluate the effects of psychodrama group therapy and pharmacotherapy on neurochemical metabolism in the first episode depression using 1HMRS methodology. METHOD: Eighteen drug-free female patients with diagnosed first-episode major depression according to DSM-IV criteria and 10 healthy female subjects were enrolled in the study. The Hamilton Rating of Depression Scale (HAM-D) was used to asses the severity of depression in each of the study participants. Proton magnetic resonance spectroscopy (1HMRS) was applied to the right prefrontal cortex both before and after treatment and the concentration of N-Asetil Aspartate (NAA), choline (Cho), and creatine (Cr) were measured. All patients were prescribed ant-depressant medication at the time of the evaluation (essitalopram 10-20 mg/g). In addition, a psychodrama group therapy session was conducted in which 10 patients participated in one 3-hour session each week. HAM-D and 1HMRS were repeated after 16 weeks. RESULTS: Prior to treatment, the HAM-D score in the patient group was 14.55±4.55 while the HAM-D score was 3.88±2.47 after 16 weeks of treatment. The severity of symptoms among the patient group was determined to be mild/moderate. No neurochemical abnormalities were identified in the right prefrontal cortex of depressed patients compared to the healthy subjects in the baseline measurements and no significant change was observed in neurochemical metabolites following treatment with pharmacotherapy or pharmacotherapy with group psychotherapy. CONCLUSION: Our results identified no neurodegeneration, cell membrane dysfunction, alterations in energy metabolism, or altered neurochemical metabolite levels in patients undergoing a first episode of mild/moderate depression. Further studies will be needed to evaluate the effects of alternate treatments and the presence or absence of neuronal damage during follow-up of patients with depression.

The comparison of pre- and post-treatment (99m)Tc HMPAO brain SPECT images in patients with obsessive-compulsive disorder.

The objective of the present study was to compare brain activation in patients with obsessive-compulsive disorder (OCD) who received pharmacotherapy (selective serotonin reuptake inhibitor (SSRI) or a SSRI-risperidone combination) with that in healthy controls using (99m)Tc-hexamethyl propyleneamine oxime (HMPAO) brain single photon emission tomography (SPECT). Twelve OCD patients achieving clinical response (seven SSRI responders, five patients responded to SSRI plus risperidone) underwent post-treatment SPECT scan. The baseline regional cerebral blood flow (rCBF) was significantly reduced in a large part of the cerebral cortex and the left cingulate gyrus in OCD patients compared with controls. After a 50% reduction of the OCD symptoms, bilaterally increased rCBF in the thalamus showed a significant effect of time in both of the patient groups. In the remitted state, although rCBF in the cingulate gyrus did not differ in SSRI responders compared with controls, patients who responded to the combination of SSRI+ risperidone showed significant hypoperfusion in the left anterior cingulate gyrus. SSRI responders had normalized rCBF in the frontal region relative to the control group. Consequently, based on our results, we attribute the observed thalamic rCBF alteration to SSRI treatment. Our results also suggested that brain perfusion changes associated with clinical remission may differ across patient subgroups.

Situation awareness in obsessive-compulsive disorder.

Past studies have suggested that OCD patients suffer memory impairment on tasks using complex stimuli that require memory for combined elements to be maintained, but not for more simplistic memory tests. We tested this with 42 OCD patients and 42 healthy controls performed a computerized situation awareness task. In addition, participants completed the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) and Maudsley Obsessive-Compulsive Inventory (MOCI). The OCD patients had poorer accuracy in integration/comprehension and perception levels than controls. There were significant correlations between situational awareness scores (i.e., visuo-spatial monitoring and processing) and Y-BOCS obsession-compulsion and slowness and doubt scores of MOCI in OCD patients. In addition, there were also significant correlations between situational awareness and controlling, cleaning, slowness, rumination and total scores of MOCI in control group. Results indicated that (I) OCD patients have problems of perception, integration, and comprehension of complex visual perceptions; (II) situation awareness deficits associated with severity and prevalence of obsessions and compulsions.

Neurological soft signs in obsessive compulsive disorder with good and poor insight.

OBJECTIVE: Obsessive compulsive disorder (OCD) is a clinically heterogeneous disorder; OCD with poor insight has been suggested to be a specific clinical subtype. Neurological soft signs (NSSs) may be helpful to identify the specific subtypes of OCD patients. METHODS: In the present study, we aimed to compare OCD patients with poor insight with OCD patients having good insight, and healthy individuals. Sixty-four OCD patients (38 with good insight and 26 with poor insight), and 32 healthy subjects were enrolled in the present study. The Overvalued Ideas Scale (OVIS) was used to determine OCD patients with poor insight. NSSs were assessed by using the Neurological Evaluation Scale (NES). RESULTS: Two OCD groups had significantly higher total NES scores compared to controls (p=.000). Compared to healthy controls, OCD patients with poor insight performed significantly worse on all NES subscales, and they had significantly more NSSs on motor coordination, and sensory integration subscales compared to the OCD with good insight group. CONCLUSION: Our results suggested that OCD patients with poor insight exhibit more extensive neurodevelopmental impairments compared to OCD patients with good insight.

The association of olanzapine-induced weight gain with peroxisome proliferator-activated receptor-gamma2 Pro12Ala polymorphism in patients with schizophrenia.

Olanzapine is a second-generation antipsychotic that may cause weight gain and metabolic syndrome in some cases. The peroxisome proliferator-activated receptor (PPAR)-gamma is an important gene in the progress of type II diabetes and metabolic syndrome. In recent studies the polymorphism of the PPAR-gamma has been studied in type II diabetes mellitus, polycystic ovary syndrome, and insulin resistance syndrome. It is aimed to evaluate the association between polymorphism of PPAR-gamma gene and olanzapine-induced weight gain. Our study comprised 95 unrelated subjects who strictly met Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) criteria for schizophrenia, and all were of Turkish origin. All patients were evaluated with rating scales, and genetic analyses were performed. We found statistically significant differences between pretreatment and posttreatment body mass index and weight change in Pro12Ala polymorphism of PPAR-gamma2. Our results suggest that genetic polymorphism of PPAR might be important in olanzapine-induced weight gain and that genetic variance of people might be considered in antipsychotic medication selection.

OCD symptoms in a sample of Turkish patients: a phenomenological picture.

This study aimed to investigate the clinical features of obsessive-compulsive disorder (OCD) and the possible association between obsessive-compulsive symptoms and culture-related characteristics in a sample of Turkish patients with OCD. We studied 141 patients with OCD (according to DSM-IV criteria) consecutively admitted to our outpatient clinic during the period from February 1998 to December 2003. We used the Turkish version of the Structured Clinical Interview for DSM-IV (SCID) to interview all patients, and the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) to assess obsessive-compulsive symptoms and severity. The onset of OCD symptoms was earlier in males. Major depression was the most common comorbid disorder (30.5%). The most commonly occurring obsessions were contamination (56.7%), aggression (48.9%), and somatic (24.1%), followed by religious (19.9%), symmetry (18.4%), and sexual imagery (15.6%). Symmetry and sexual obsessions, and checking compulsions and rituals, tended to be more common in male patients. Dirt and contamination obsessions and washing compulsions were slightly more common in females. The vast majority of patients with religious obsessions (83%) and half of the patients with sexual obsessions had compulsions that included religious practices. Also, patients with sexual and religious obsessions had delayed seeking professional help.

Memory function in patients with obsessive compulsive disorder and the problem of confidence in their memories: a clinical study.

AIM: To examine obsessive-compulsive patients for memory of obsessive-compulsive relevant material and confidence in their memory. METHODS: Memory function was examined by a recognition task using neutral and obsessive-compulsive relevant sentences in 32 patients with obsessive-compulsive disorder and 31 control subjects. We also investigated the participants' confidence in the accuracy of their recognition. The severity of obsessive-compulsive disorder was evaluated by using the Yale-Brown Obsessive Compulsive Scale. The Maudsley Obsessive Compulsive Questionnaire, the Hamilton Depression Rating Scale, and the State-Trait Anxiety Inventory were also administered to the two groups. RESULTS: Whereas obsessive-compulsive disorder patients were not significantly different from control subjects on measures of recognition memory for both obsessive-compulsive relevant and neutral material, they were significantly less confident in the memory for obsessive-compulsive relevant and neutral sentences. Also, the State-Trait Anxiety Inventory (STAI) scores were negatively correlated with the recognition performance of obsessive-compulsive disorder relevant sentences and the levels of confidence in memory in the obsessive-compulsive disorder group. The obsessive-compulsive patients with checking compulsions were not different from non-checking obsessive-compulsive patients. CONCLUSION: Our results suggest that obsessive-compulsive patients experience difficulties in confidence in their memory, possibly related to anxiety rather than primary memory deficits.

Psychiatric disorders and functioning in hepatitis B virus carriers.

The authors compared asymptomatic hepatitis B virus carriers and healthy subjects in terms of their psychological state. Participants (43 asymptomatic hepatitis B virus carriers and 43 healthy comparison subjects) completed self-report questionnaires. Psychiatric disorders and psychosocial functioning were evaluated with structured clinical interviews and the Global Assessment of Functioning scale. Hepatitis B virus carriers were more likely to have psychiatric disorders than comparison subjects (30.2% vs. 11.6%). Also, carriers had significantly higher depression and anxiety scores and lower Global Assessment of Functioning scores than did comparison subjects. Worries about contamination and illnesses related to hepatitis B infection were associated with the presence of psychiatric disorder. The results suggest that asymptomatic hepatitis B virus carriers need emotional support.
