RESUMO
Interactions between childhood trauma (CT) and dissociation can contribute to psychiatric disturbances. We explored this phenomenon in relation to behavioral addictions (BAs) in a sample (n = 633) of young adults (age: 18-34 years). Self-report measures investigating CT, dissociation, and symptoms related to gambling disorder, internet gaming disorder, problematic social media use, exercise dependence and compulsive buying were used. Scales related to BAs were summarized into a single measure ("Total Behavioral Addiction Index" - TBAI) for inferential analyses. A model analyzing the direct and indirect effects of CT on TBAI through the mediation of pathological dissociation was performed, controlling for confounding factors. Measures on CT, dissociation, and TBAI were significantly associated with each other (all p < .001). The total effect of CT on TBAI was significant (B = 0.063; CI: 0.045; 0.081); pathological dissociation significantly mediated such association (B = 0.023; CI: 0.013; 0.036). Our findings support the possibility that the interaction between CT and dissociation contributes to increase disturbances related to BAs.

PURPOSE: Studies have shown significant associations of dissociative symptoms with both eating and addictive disorders; however, the different forms of dissociation have been relatively understudied in relation to food addiction (FA). The main aim of this study was to investigate the association of certain forms of dissociative experiences (i.e., absorption, detachment and compartmentalization) with FA symptoms in a nonclinical sample. METHODS: Participants (N = 755; 543 women; age range: 18-65; mean age: 28.22 ± 9.99 years) were evaluated using self-report measures of FA, dissociation, eating disturbances, and general psychopathology. RESULTS: Compartmentalization experiences (defined as pathological over-segregation of higher mental functions) were independently associated with FA symptoms (ß = 0.174; p = 0.013; CI = [0.008; 0.064]) even when confounding factors were controlled for. CONCLUSION: This finding suggests that compartmentalization symptoms can have a role in the conceptualization of FA, with such two phenomena possibly sharing common pathogenic processes. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.

Background: Insufficient effectiveness and a difficult tolerability profile of antidepressant drugs for the treatment of major depressive disorder (MDD) have been reported, and polyunsaturated fatty acids (PUFAs) have been posited as reliable therapeutic alternatives. The present study investigated the efficacy of omega-3 PUFAs as monotherapy for MDD. Methods: Two well-trained reviewers independently looked at the most significant randomized clinical trials (RCTs) from the PubMed database regarding PUFAs' employment in MDD compared to placebo; "major depressive disorder" and "omega-3 fatty acids," or "omega-6 fatty acids," or "polyunsaturated fatty acids (PUFA)," or "n - 3 polyunsaturated fatty acids," or "eicosapentaenoic acid (EPA)," or "docosahexaenoic acid (DHA)" were used as the medical subject keywords. Results: Of the initial 96 potential RCTs based on titles and abstracts, 82 studies did not meet the inclusion criteria and were excluded. Six studies were excluded from the remaining 14 after full text revision. Eight RCTs met all the inclusion/exclusion criteria without reporting clear evidence of PUFAs' effectiveness in the treatment of MDD. Conclusion: At present, there is no opportunity to recommend the use of omega-3 PUFAs monotherapy for the treatment of MDD, although their supplementation may be useful in some specific populations.

One of the worrying concomitants of problematic use of Internet (PUI) is aggression. Although the mechanisms underlying such link have not been completely clarified, it has been suggested that problematic use of social media and online videogames (i.e., two common forms of PUI among young adults) lead to increased sleep disturbances which, in turn, represent a relevant trigger for aggression. We have tested this hypothesis in a sample (N = 480) of young individuals (351 females and 129 males; mean age: 21.76 ± 1.92 years; range: 18-24). Self-report measures investigating symptoms related to social media addiction (SMA), Internet gaming disorder (IGD), insomnia severity, and aggression were used. Mediational models analyzing the direct and indirect associations of SMA- and IGD-related symptoms on aggression severity through insomnia-related symptoms were performed controlling for confounding factors. The models showed that the total effects of SMA-related symptoms (B = 0.018; p = .010) and of IGD-related symptoms (B = 0.018; p = .041) on aggression severity were significant and that these associations were mediated by insomnia-related symptoms (respectively, p < .001 and p = .003). Our findings support the potential mediating role of insomnia severity in the association of SMA- and IGD-related disturbances with levels of aggression.

PURPOSE: Although the association between problematic use of the internet and eating disorders (EDs) in young adults has been previously established, its underlying mechanisms have not been completely clarified. It has been suggested that exposure to idealized very thin and toned body images (e.g., "thinspiration" and "fitspiration" trends) on social media might lead to increased feelings of body dissatisfaction which, in turn, can represent a trigger for EDs. We have tested this hypothesis in a sample (N = 721) of young adults (504 females, mean age: 24.13 ± 3.70 years; range 18-34). METHODS: Self-report measures investigating symptoms related to social media addiction (SMA), muscle dysmorphia (MD), and EDs were used. A mediational model analyzing the direct and indirect effects of SMA-related symptoms on ED-related symptoms through the mediating role of MD-related symptoms was performed controlling for confounding factors (e.g., socio-demographic variables, substances use, body mass index, psychopathological distress). RESULTS: The model showed that the total effect of SMA-related symptoms on ED-related symptoms was significant (B = 0.213; p = 0.022) and that this association was mediated by MD-related symptoms (B = 0.083; p = 0.021). DISCUSSION: Our findings support the possibility that MD-related symptoms play a relevant role in mediating the association between SMA severity and ED pathology. LEVEL OF EVIDENCE: Level III, evidence obtained from well-designed cohort or case-control analytic studies.

INTRODUCTION: Self-Help Plus (SH+) is a group-based psychological intervention developed by the World Health Organization for managing stress. OBJECTIVE: To assess the effectiveness of SH+ in preventing mental disorders in refugees and asylum seekers in Western Europe. METHODS: We conducted a randomized controlled trial in 5 European countries. Refugees and asylum seekers with psychological distress (General Health Questionnaire score ≥3), but without a Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) or ICD/10 diagnosis of mental disorder, as assessed with the Mini International Neuropsychiatric Interview (MINI), were randomized to SH+ or enhanced treatment as usual (ETAU). The primary outcome was the frequency of mental disorders with the MINI at 6 months. Secondary outcomes included the frequency of mental disorders at postintervention, self-identified problems, psychological symptoms, and other outcomes. RESULTS: Four hundred fifty-nine individuals were randomly assigned to SH+ or ETAU. For the primary outcome, we found no difference in the frequency of mental disorders at 6 months (Cramer V = 0.007, p = 0.90, RR = 0.96; 95% CI 0.52-1.78), while the difference significantly favored SH+ at after the intervention (secondary outcome, measured within 2 weeks from the last session; Cramer V = 0.13, p = 0.01, RR = 0.50; 95% CI 0.29-0.87). CONCLUSIONS: This is the first randomized indicated prevention study with the aim of preventing the onset of mental disorders in asylum seekers and refugees in Western Europe. As a prevention effect of SH+ was not observed at 6 months, but rather after the intervention only, modalities to maintain its beneficial effect in the long term need to be identified.

BACKGROUND: 22q11.2 deletion syndrome (22q11.2DS) is considered as the genetic model of schizophrenia. However, its polymorphic nature has led researchers to further investigate its neuropsychiatric manifestations. METHODS: We enrolled 56 adults (38 men, 18 women) diagnosed with 22q11.2DS. All subjects were evaluated by a multidisciplinary team. The neuropsychiatric features were investigated by means of clinical and neurophysiological evaluation (video-EEG). RESULTS: Thirty per cent of our patients were left-handed. Fifty-eight per cent had a low IQ, and 22 of 56 subjects had psychotic disorders (13 of 22 with schizophrenia). Eighteen patients reported at least one seizure in their lifetime, and ten were diagnosed with epilepsy; among them, seven had genetic generalised epilepsy (GGE), and five of seven showed features suggestive of juvenile myoclonic epilepsy (JME). Video-EEG recordings revealed generalised epileptiform abnormalities in 24 of 56 cases. Besides, only one patient with epilepsy had a cardiac malformation. Lastly, 31 of 56 subjects presented with parkinsonism, 16 of whom were taking neuroleptics. None of the 15 patients with parkinsonism not related to neuroleptic therapy was diagnosed with epilepsy, compared with 6 of those taking antipsychotics. CONCLUSIONS: 22q11.2DS is characterised by left-handedness and neuropsychiatric features such as cognitive impairment, schizophrenia, epilepsy and parkinsonism. GGE, mostly the JME phenotype, is the predominant epilepsy type. The significant association between 22q11.2DS and parkinsonian features confirms these patients' genetic susceptibility to parkinsonism. Despite the lack of any conclusive evidence, our study suggests a possible relationship between the analysed clinical variables: (1) an inverse correlation between low IQ/psychosis/epilepsy and major cardiac diseases; (2) a direct association between psychosis and both mental delay and epilepsy; and (3) an inverse correlation between parkinsonism and epilepsy.

INTRODUCTION: The stress-diathesis model of psychotic disorders describes, in vulnerable individuals, the role of psychosocial stress in the onset and exacerbation of psychotic symptoms. Another interesting approach to the study of vulnerability in the development of psychosis is represented by the basic symptoms concept. OBJECTIVE: The present study aims at proposing an integration between these two models and investigating possible associations between psychotic symptoms, basic symptoms, perceived stress, and life events in a sample of patients affected by schizophrenia (SZ), schizoaffective (SA), and bipolar disorder with and without psychotic symptoms. METHODS: 112 patients were recruited in two university hospitals. Severity of psychiatric symptoms (Positive and Negative Syndrome Scale, PANSS), basic symptoms (Frankfurt Complaint Questionnaire, FCQ), perceived stress (Stress-related Vulnerability Scale, SVS), and life events (Paykel's interview for recent life events) were assessed. RESULTS: Patients affected by bipolar disorder (both with and without psychotic symptoms) showed a higher number of independent life events (p < 0.01) and tended to report more frequently at least 1 life event in the previous 6 months (p < 0.01) than patients affected by SZ or SA disorder. No differences emerged between the study groups in perceived stress nor in measures of basic symptoms. In the whole sample, a logistic regression analysis showed that the SVS total score (p < 0.05) and PANSS total score (p < 0.001) were associated with the presence of psychotic symptoms. CONCLUSIONS: In the study sample, life events and basic symptoms did not play a major role in influencing psychotic symptoms, compared to the subjective perception of stress and the severity of psychopathology. Taken together, these results can be informative for rehabilitation therapies aimed at enhancing resilience and coping strategies in this vulnerable group of patients.

INTRODUCTION: The last decade has witnessed a resurgence of interest in the clinician's subjectivity and its role in the diagnostic assessment. Integrating the criteriological, third-person approach to patient evaluation and psychiatric diagnosis with other approaches that take into account the patient's subjective and intersubjective experience may bear particular importance in the assessment of very young patients. The ACSE (Assessment of Clinician's Subjective Experience) instrument may provide a practical way to probe the intersubjective field of the clinical examination; however, its reliability and validity in child and adolescent psychiatrists seeing very young patients is still to be determined. METHODS: Thirty-three clinicians and 278 first-contact patients aged 12-17 years participated in this study. The clinicians completed the ACSE instrument and the Brief Psychiatric Rating Scale after seeing the patient, and the Profile of Mood State (POMS) just before seeing the patient and immediately after. The ACSE was completed again for 45 patients over a short (1-4 days) retest interval. RESULTS: All ACSE scales showed high internal consistency and moderate to high temporal stability. Also, they displayed meaningful correlations with the changes in conceptually related POMS scales during the clinical examination. DISCUSSION: The findings corroborate and extend previous work on adult patients and suggest that the ACSE provides a valid and reliable measure of the clinician's subjective experience in adolescent psychiatric practice, too. The instrument may prove to be useful to help identify patients in the early stages of psychosis, in whom subtle alterations of being with others may be the only detectable sign. Future studies are needed to determine the feasibility and usefulness of integrating the ACSE within current approaches to the evaluation of at-risk mental states.

INTRODUCTION: The clinician's subjective experience can be a valuable element for diagnosis and treatment. A few factors have been recognized that affect it, such as the patient's personality, the severity of psychopathology, and diagnosis. Other factors, such as patient's and clinician's gender, have not been specifically investigated. The aim of this study is to explore the impact of gender differences on the clinician's subjective experience in a large sample of psychiatric patients. METHODS: The study involved 61 psychiatrists and 960 patients attending several inpatient and outpatient psychiatric settings. The clinicians completed the Assessment of Clinician's Subjective Experience (ACSE) questionnaire after observing each patient for the first time. RESULTS: In multivariate analysis, higher scores on the Difficulty in Attunement (p < 0.001), Engagement (p<0.05), and Impotence (p<0.01) scales were significantly associated with female clinician gender, whereas higher scores on the Tension and Disconfirmation scales were significantly associated with male clinician gender. The scores on all ACSE dimensions were also associated with the severity of psychopathology. CONCLUSION: The findings suggest that clinician's gender might affect a clinician's emotional response toward patients. Specific attention to this issue might be useful in clinical situations, not only in terms of promoting gender-balanced teams but also in terms of enhancing self-observation in clinicians evaluating patients for the first time.
RESUMO
INTRODUCTION: The clinical encounter is still at the core of the psychiatric evaluation. Since the diagnostic process remains basically clinical in nature, several authors have addressed the complexity of the clinical reasoning process and highlighted the role played by intersubjective phenomena and clinician's feelings. Some recent studies have supported the view of a significant link between the clinician's subjective experience during the assessment and the diagnosis made. In a globalized world, this issue requires a careful reflection, since cultural differences may affect the intersubjective atmosphere of the encounter, which may indirectly influence the clinician's thinking. METHODS: We used a previously validated instrument, named Assessment of Clinician's Subjective Experience (ACSE), to compare the clinician's subjective experience during the evaluation of Italian patients with the subjective experience of the same clinician during the assessment of foreign patients. The 2 patient groups (n = 42 each) were individually matched for known potential confounders (age, sex, categorical diagnosis, and clinical severity). RESULTS: We found no significant differences in mean scores on all ACSE dimensions (tension, difficulty in attune-ment, engagement, disconfirmation, and impotence), which suggests that cultural diversity did not substantially affect the clinician's subjective experience. However, the lack of information about the native country and linguistic proficiency of about a quarter of foreign patients may have limited the possibility to detect subtle or specific differences, especially with regard to the clinician's empathic attunement. CONCLUSIONS: Although further investigation is needed, our preliminary findings may have significant implications for the reflection upon the clinician's empathic experience as well as pragmatic consequences for the act of psychiatric diagnosis in the cross-cultural encounter.

BACKGROUND: Preliminary studies have tested nicotine as a novel treatment for OCD patients who respond partially/incompletely or not at all to first and second-line treatment strategies, with the former represented by SSRIs or clomipramine, and the latter by switching to another SSRI, or augmentation with atypical antipsychotics, and/or combination with/switching to cognitive-behavioural therapy. Some studies found nicotine-induced reduction of obsessive thoughts and/or compulsive behaviour in OCD patients. We aimed to evaluate the efficacy of nicotine administration in OCD patients. METHODS: We searched the PubMed, ScienceDirect Scopus, CINHAL, Cochrane, PsycINFO/PsycARTICLES, and EMBASE databases from inception to the present for relevant papers. The 'Preferred Reporting Items for Systematic Review and Meta-Analyses' (PRISMA) standards were used. We included all studies focusing on the effects of nicotine administration on OCD patients' obsessions or compulsions. Studies could be open-label, cross-sectional, randomized controlled trials, case series or case reports. RESULTS: A total of five studies could be included. Nicotine administration may ameliorate behavioural features and recurrent thoughts of severe, treatment-resistant OCD patients; however, in one study it was not associated with OC symptom improvement or cognitive enhancement across various executive function subdomains. CONCLUSIONS: Although encouraging, the initial positive response from the use of nicotine in OCD needs testing in large controlled studies. This, however, raises ethical issues related to nicotine administration, due to its addiction potential, which were not addressed in the limited literature we examined. As an alternative, novel treatments with drugs able to mimic only the positive effects of nicotine could be implemented.
RESUMO
BACKGROUND: A link between depression and insecure attachment has long been postulated. Although many studies examined the relationship between depressive symptoms and attachment, relatively few studies were performed on patients diagnosed with depression. Also, research on patients with bipolar disorder is scarce. OBJECTIVE: We aimed at testing the association between attachment insecurity and unipolar and bipolar depression. METHODS: We studied 21 patients with bipolar disorder, current episode depressed, and three age- and sex-matched groups, each consisting of 21 individuals: patients with major depressive disorder, recurrent episode; patients with epilepsy; non-clinical participants. The Experience in Close Relationships questionnaire was used to assess adult attachment style. RESULTS: Patients with both bipolar and unipolar depression displayed significantly higher scores on attachment-related avoidance as compared with patients with epilepsy and non-clinical participants. Also, patients with bipolar depression scored significantly higher on attachment-related anxiety than all other groups. In both psychiatric groups, attachment dimensions were not significantly correlated with global clinical severity or severity of depression. CONCLUSION: Despite some study limitations, our results are consistent with some previous studies and provide support to Bowlby's seminal hypothesis that attachment insecurity may predispose to depression. Attachment theory may provide a valuable theoretical framework for future research and for guiding treatment.
RESUMO
The relationships of personal resources with symptom severity and psychosocial functioning have never been tested systematically in a large sample of people with schizophrenia. We applied structural equation models to a sample of 921 patients with schizophrenia collected in a nationwide Italian study, with the aim to identify, among a large set of personal resources, those that may have an association with symptom severity or psychosocial functioning. Several relevant demographic and clinical variables were considered concurrently. Poor service engagement and poor recovery style, as well as older age and younger age at onset, were related to greater symptom severity and poorer social functioning. Higher resilience and higher education were related to better social functioning only. Poor problem-focused coping and internalized stigma, as well as male gender and depression, were related to symptom severity only. The explored variables showed distinctive and partially independent associations with symptom severity and psychosocial functioning. A deeper understanding of these relationships may inform treatment decisions.

Individuals with eating disorders (EDs) often report a history of early traumatization. Although great attention has been paid to certain types of trauma, such as sexual and emotional abuse, less is known about the occurrence of childhood neglect in individuals with EDs. The aim of the present meta-analysis was to provide an estimate of the prevalence of childhood emotional neglect (EN) and physical neglect (PN) in individuals with EDs. A systematic literature search, a critical appraisal of the collected studies, and a meta-analysis were conducted. An electronic search of EMBASE, PsycINFO, PubMed, and the Cochrane Library from the inception of these databases up to July 2015 was performed. The final meta-analyzed data set included 7 studies focusing on EN in EDs (N = 963) and 6 on PN in EDs (N = 665). Our meta-analytic data showed that among individuals with EDs, the prevalence of childhood EN is 53.3%, whereas 45.4% reported experience of childhood PN. These preliminary findings confirm the high prevalence of childhood EN and PN in ED samples compared to the general population and underline the importance of systematically screening for the presence of neglect as a possible traumatic experience in individuals with EDs, as its presence may have important consequences for the therapeutic approach.

BACKGROUND: Individuals with psychiatric disorders incur an increased risk of morbidity and mortality, with higher prevalence of cardio-metabolic risk factors s largely contributing to a significant reduction in life expectancy. OBJECTIVES: The aim of the present study was at evaluating the clinical effectiveness of an educational intervention targeting lifestyle habits in patients with mood and psychotic disorders. METHODS: Patients (n = 32) were randomly assigned to receive, in addition to the pharmacological treatment, either five sessions of group psychoeducation focused on healthy lifestyle or five sessions of a control group therapy. RESULTS: Both psychopathological severity (i.e. the brief psychiatric rating scale) and lifestyle quality (i.e. physical activity, sleep quality and adherence to the Mediterranean diet) improved significantly over time in patients who underwent specific psychoeducational sessions but not in the controls. CONCLUSIONS: These findings add to the accumulating evidence that educational interventions focused on lifestyle habits can ameliorate general and mental health in patients with psychiatric disorders and suggest that educational programs represent an effective non-pharmacological intervention to manage drug-induced cardiometabolic disturbances.

During the nineteenth century and the first decade of the twentieth, students of pathology such as Cesare Lombroso (1835-1909), the author of the excerpt presented here, became involved in observing, investigating and theorizing about the phenomena of Spiritualism, and mediumship in particular. The Classic Text presented here consists of an excerpt from Lombroso's writings which focus on the Italian medium Eusapia Palladino (1854-1918), who greatly influenced Lombroso's beliefs. Lombroso illustrates neglected theoretical ideas combining the interaction of pathology and what seem to be real psychic phenomena that have not received much attention in historical studies.

OBJECTIVES: Overlapping neural system dysfunctions, mainly involving the secondary somatosensory cortex (S2), the anterior cingulate cortex (ACC) and the anterior insular cortex (AIC), seem to be related to both pain-perception abnormalities and psychotic symptoms in schizophrenia (SCZ) and bipolar disorder (BD). Laser-evoked potentials (LEPs) were used to investigate pain-perception and central pain-processing abnormalities in SCZ, bipolar I disorder (BD-I), and bipolar II disorder (BD-II), and to evaluate their relationship with history of psychosis, and social-cognitive and functional impairments. METHODS: Twenty patients with SCZ, 17 patients with BD-I, and 21 patients with BD-II who were all under similar pharmacological treatment underwent clinical, functional, and neuro-psychological assessment. LEPs were analyzed in patients and 19 healthy subjects (HS). LEPs elicit responses reflecting the activity of the S2 (N1 wave) and the ACC/AIC cortices (N2/P2 complex). A four-group ANOVA was conducted between patients and HS to compare pain-perceptive thresholds (PThs), N1, and N2/P2-LEP components. RESULTS: Compared to HS: (i) patients with SCZ showed pain-processing and pain-perception abnormalities, as revealed by significantly higher PTh (P<.01), and lower N1 (P<.01) and N2/P2 (P<.01) amplitudes, (ii) patients with BD-I showed only pain-processing abnormalities, as revealed by significantly lower N1 (P<.05) and N2 (P<.01) amplitudes; and patients with BD-II did not differ for any of the LEP variables investigated. N1 and N2 amplitudes negatively correlated to history of psychosis (P<.01), social-cognition (P<.05), and real-world functioning (P<.01) measures in the whole group of patients. CONCLUSIONS: To the best of our knowledge, this is the first study comparing central pain processing in patients with SCZ, BD-I, and BD-II. Our results suggest that pain-processing abnormalities may represent a novel locus of interest for research investigating trait markers of the psychosis spectrum.

BACKGROUND: Classical psychopathology greatly valued the interaction between clinician and patient, and assigned to the clinician's subjective experience a significant role in the diagnostic process. Psychoanalysis, too, ascribed a privileged position to the clinician's feelings and empathic participation in the assessment and deep understanding of the patient. This study aimed at testing the traditional, though still relatively unexplored empirically, tenet that particular diagnostic groups elicit distinct and diagnostically useful reactions from clinicians. SAMPLING AND METHODS: The study was performed in several psychiatric inpatient and outpatient units in Rome, Italy. The clinicians completed the Assessment of Clinician's Subjective Experience (ACSE) questionnaire and other standardized assessment instruments when they evaluated a previously unknown patient. All adult patients diagnosed with schizophrenia (n = 119), cluster B personality disorder (n = 114), manic or mixed bipolar I episode (n = 59), and unipolar depression or anxiety disorder (n = 130) were included in the study, for a total of 422 patients evaluated by 35 clinicians. RESULTS: We found a significant and theoretically consistent relationship between the clinicians' pattern of subjective experience during the first visit and patients' clinical diagnoses. Patients with unipolar depression/anxiety showed significantly lower scores than the other groups on all ACSE scales except engagement; patients with schizophrenia displayed significantly higher scores than the other groups on difficulty in attunement, and significantly higher scores than patients with cluster B personality disorder on impotence. Compared with the other groups, the patients with cluster B personality disorder displayed significantly lower scores on engagement, and significantly higher scores on disconfirmation. In multivariate models controlling for patient's age and education, symptom severity, clinician's sex, duration of visit and setting, diagnosis remained a significant predictor of scores on all ACSE scales except for impotence. CONCLUSIONS: The main limitations of the study are its reliance on clinical diagnoses and the non-independence of assessments. Further studies based on diagnoses made by a third observer through standardized instruments are needed to provide a most stringent test of the hypothesis that different diagnoses are associated with distinct profiles of clinicians' subjective experience. This study provided intriguing, though preliminary, evidence that the clinician's subjective experience may play a useful role in the diagnostic process. Time may have come to reintroduce the concept of intersubjectivity at the core of the diagnostic process.

BACKGROUND: Despite the theoretical and clinical relevance of psychopathological dimensions in obsessive-compulsive disorder (OCD), no studies to date have investigated their possible association with obsession subtypes. Thus, we aimed to examine whether, in OCD patients, anger and other psychopathological dimensions are associated with specific obsession subtypes. METHODS: We consecutively recruited 57 first-visit OCD patients (66.7% female, mean age 34 years) at our Psychiatric Outpatient Clinic. We used the point biserial coefficient (rpbi) to measure the correlation between psychopathological dimensions and obsession subtypes. RESULTS: We found significant correlations (p < 0.05) between the following: (1) anger/aggressiveness dimension and aggressive, contamination, and sexual obsessions; (2) apprehension/fear dimension and contamination, religious, and somatic obsessions; (3) sadness/demoralization dimension and contamination and somatic obsessions; (4) impulsivity dimension and aggressive and sexual obsessions, and (5) somatic concern/somatization dimension and contamination and somatic obsessions. We also found that OCD patients with comorbid obsessive-compulsive personality disorder--but not schizotypal or histrionic disorders--showed higher levels (p < 0.05) of obsessiveness/iterativity and anger/aggressiveness than OCD patients without the personality disorder. CONCLUSIONS: Anger and other psychopathological dimensions seem to be linked with specific obsession subtypes in OCD patients, suggesting an association between these dimensions and OCD.
