RESUMEN
Persons with obsessive-compulsive disorder (OCD) are often impaired in their daily level of functioning due to their time-consuming obsessions and/or compulsions. To date, however, studies are lacking that quantify how much time persons with OCD actually spend on activities of daily living. Therefore, the current study assessed 13 daily life activities (in minutes) with a self-report questionnaire in 299 persons with OCD at admission to inpatient treatment and 300 age- and sex-matched persons without OCD. A majority of persons with OCD indicated that they experienced obsessions and/or compulsions when leaving (84%) and cleaning (70%) the apartment, grocery shopping (66%), changing clothes (66%), and showering with (62%) and without (63%) shampooing. Persons with OCD who experienced obsessions and/or compulsions during a given daily life activity-but not those who did not experience obsessions and/or compulsions during these activities-reported longer durations for performing 10 of the 13 activities than persons without OCD. For most activities, longer durations related weakly but significantly to higher OCD symptom severity. Results indicate that the duration of daily life activities seems to depend more on whether persons with OCD experience obsessions and/or compulsions during a specific activity and less on whether a person is diagnosed with OCD in general. Future studies may use other assessment methods that allow for tracking the duration in daily life in real time.

BACKGROUND AND OBJECTIVES: Scrupulosity, despite its considerable prevalence and morbidity, remains under-investigated. The present study develops and examines the psychometric properties of a comprehensive assessment tool, the Scrupulosity Inventory (SI). METHODS: The SI, along with other measures of obsessive-compulsive disorder (OCD) and perfectionism, were administered to a sample (N = 150) of college undergraduates similar in size to other scale development studies of related measures. We conducted exploratory and confirmatory factor analyses of the SI, examined its convergent and divergent validity, and assessed its ability to predict categorical diagnoses of scrupulosity using a receiver operator characteristic analysis. RESULTS: We found a well-fitting confirmatory bifactor model (RMSEA = 0.049) with a strong general Scrupulosity factor ( [Formula: see text] ) and specific factors for Personal Violations ( [Formula: see text] ), Ritualized Behavior ( [Formula: see text] ), Interference with Life ( [Formula: see text] ), and Problem Pervasiveness ( [Formula: see text] ). As predicted, we also found the strongest convergence (r = 0.63) between the SI and the Penn Inventory of Scrupulosity (PIOS), intermediate convergence (r = 0.54) between the SI and Perfectionism Inventory (PI), and weaker convergence (r = 0.47) between the SI and YBOCS. Finally, we found that a categorical diagnosis of scrupulosity was highly predicted by the SI (AUC = 0.84), less well-predicted by the PIOS (AUC = 0.75) and less well predicted by the YBOCS (AUC = 0.69). LIMITATIONS: This study was conducted among a sample of undergraduates at a religiously affiliated university. CONCLUSIONS: These results suggest utility in using the SI to measure the severity of scrupulosity symptoms and that scrupulosity and OCD may present significantly different clinical features.

The Diagnostic and Statistical Manual 5th ed. defines obsessions in obsessive-compulsive disorder (OCD) as frequent, persistent, intrusive, unwanted thoughts that provoke anxiety and distress and lead to attempts to neutralize them with either thoughts or actions. However, no systematic review has yet evaluated characteristics that are specific to obsessions occurring in OCD. The aim of the current systematic review and meta-analysis was to investigate the specific features of obsessions occurring in OCD by comparing them to both obsessionally and non-obsessionally-themed intrusions in non-clinical and other clinical populations. Based on a registered protocol, 832 records were found, of which 15 were included in the systematic review and meta-analysis, with a total of 1891 participants. Obsessionally-themed intrusions that occur among those with OCD caused more distress, guilt, negative emotion and interference as compared to similarly-themed intrusions that occur within the general population. The distinction between obsessionally-themed intrusions among those with OCD as compared to those occurring in anxiety and depressive disorder primarily revolves around a higher level of persistence, pervasiveness and distress associated with their occurrence. Further, unacceptability, uncontrollability, ego-dystonicity, alienness, guilt, the form of the intrusion, association with the self and lack of any basis in reality also differentiates between obsessions and intrusions occurring in other disorders. Obsessions share many characteristics with thoughts occurring in other disorders and can be distinguished using a combination of characteristics specific to individual disorders.

BACKGROUND AND OBJECTIVES: Preliminary findings suggest that acceptance and commitment therapy-informed exposure therapy may be an effective treatment for obsessive-compulsive disorder (OCD). However, there is a lack of experimental studies that have examined immediate effects of acceptance-based strategies during exposure to disorder-relevant stimuli in persons with OCD. METHODS: Fifty-three inpatients (64% female) with OCD participated in an experimental study during which they were exposed to obsessive-compulsive washing-relevant pictures and were instructed to either passively view these pictures for 5 s (neutral condition), to accept their feelings (acceptance condition) or to intensify their feelings (exposure condition) for 90 s each. RESULTS: The acceptance condition led to higher acceptance and lower unpleasantness of patients' current feelings compared to the neutral condition and to lower strength of obsessions and urge to perform compulsions but only when compared to the exposure condition. Higher self-reported OCD symptom severity related to higher unpleasantness and strength of obsessions, particularly in the neutral condition. LIMITATIONS: Future studies need to test whether the current findings translate to other stimuli and other forms of obsessions and compulsions. Due to the short duration, the exposure condition might have only mimicked the early phase of exposure and response prevention. CONCLUSIONS: Acceptance-based strategies during cue exposure immediately increase acceptance of and reduce unpleasant feelings. In line with the rationale of acceptance-based treatment approaches, which do not aim at immediate disorder-specific symptom reductions, effects on obsessions and compulsions may be more delayed or require repeated training sessions.

Objective. Deep brain stimulation is a treatment option for patients with refractory obsessive-compulsive disorder. A new generation of stimulators hold promise for closed loop stimulation, with adaptive stimulation in response to biologic signals. Here we aimed to discover a suitable biomarker in the ventral striatum in patients with obsessive compulsive disorder using local field potentials.Approach.We induced obsessions and compulsions in 11 patients undergoing deep brain stimulation treatment using a symptom provocation task. Then we trained machine learning models to predict symptoms using the recorded intracranial signal from the deep brain stimulation electrodes.Main results.Average areas under the receiver operating characteristics curve were 62.1% for obsessions and 78.2% for compulsions for patient specific models. For obsessions it reached over 85% in one patient, whereas performance was near chance level when the model was trained across patients. Optimal performances for obsessions and compulsions was obtained at different recording sites.Significance. The results from this study suggest that closed loop stimulation may be a viable option for obsessive-compulsive disorder, but that intracranial biomarkers are patient and not disorder specific.Clinical Trial:Netherlands trial registry NL7486.

Despite the prevalence of atypical sexual thoughts in OCD presentations, research suggests that treatment providers often misclassify OCD with pedophilic obsessions (P-OCD) as pedophilic disorder. Such misdiagnoses can have adverse effects including inappropriate treatment, worsening of symptoms, and potential legal complications. Given these iatrogenic effects, clinicians must be competent in differentiating between these two conditions. To clarify the difficult differential between P-OCD and pedophilic disorder, the current paper provides readers with two vignettes that illustrate the differential process. These vignettes highlight important distinctions in symptom presentations and common pitfalls when assessing for P-OCD and pedophilic disorder. The first vignette describes a 32-year-old married woman who experienced pedophilic-themed intrusive thoughts, leading her to avoid children and certain interactions with her daughter. The second vignette describes a 42-year-old married man who experienced ego-dystonic attraction toward minors, particularly 8-10-year-old girls. Following these vignettes, treatment implications and forensic implications are discussed. Finally, recommendations for future clinical and empirical work are made.

Obsessive-compulsive symptoms are frequent in schizophrenia-spectrum disorders and often cause differential diagnostic challenges, especially in first-contact patients. Drawing upon phenomenology of cognition, we critically review classic and contemporary psychopathological notions of obsessive-compulsive phenomena and discuss their relevance for differential diagnosis between obsessive-compulsive disorder (OCD) and schizophrenia-spectrum disorders. The classic psychopathological literature defines true obsession as intrusions with intact resistance and insight and regards these features as essential to the diagnosis of OCD. In schizophrenia, the classic literature describes pseudo-obsessive-compulsive phenomena characterized by lack of resistance and an affinity with other symptoms such as thought disorder and catatonia. By contrast, the notions of obsession and compulsion are broader and conceptually vague in current diagnostic systems and research instruments. Here, these phenomena overlap with delusions as well as various subjective and behavioral anomalies, which we discuss in detail. Furthermore, we examine a link between obsessive-compulsive phenomena and disturbances of basic structures of experience in schizophrenia-spectrum disorders addressed in contemporary psychopathological research. We suggest that these experiential alterations have relevance for differential diagnosis and early detection in this complex symptom domain.

PURPOSE: Orthorexia nervosa (ON) is an obsession for healthy and proper nutrition. Diagnostic criteria for ON are lacking and the psychopathology of ON is still a matter of debate in the clinical and scientific community. Our aim was to better understand the Italian clinical and scientific community's opinion about ON. METHODS: Anonymous online survey for Italian healthcare professionals, implemented with the REDCap platform and spread through a multicenter collaboration. Information was gathered about socio-demographic, educational and occupational features, as well as about experience in the diagnosis and treatment of EDs. The main part of the survey focused on ON and its features, classification and sociocultural correlates. RESULTS: The survey was completed by 343 participants. Most responders (68.2%) considered ON as a variant of Eating Disorders (EDs), and 58.6% a possible prodromal phase or evolution of Anorexia Nervosa (AN). Most participants (68.5%) thought the next DSM should include a specific diagnostic category for ON, preferably in the EDs macro-category (82.1%). Moreover, 77.3% of responders thought that ON deserves more attention on behalf of researchers and clinicians, and that its treatment should be similar to that for EDs (60.9%). Participants thinking that ON should have its own diagnostic category in the next DSM edition had greater odds of being younger (p = 0.004) and of considering ON a prodromic phase of another ED, such as AN (p = 0.039). DISCUSSION: Our survey suggests that the scientific community still seems split between those who consider ON as a separate disorder and those who do not. More research is still needed to better understand the construct of ON and its relationship with EDs; disadvantages and advantages of giving ON its own diagnosis should be balanced. LEVEL OF EVIDENCE: V (descriptive cohort study).

The purpose of the study was to characterize repetitive phenomena in Williams syndrome (WS). The parents of 60 subjects with WS completed the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) or Children's Y-BOCS, the Yale Global Tic Severity Scale, the Stereotyped Behavior Scale, and the Spence Children's Anxiety Scale-Parent Version. Nineteen males and 41 females participated in the study. Six subjects (10%) had obsessions only, six (10%) had compulsions only, and eleven (18%) had at least one obsession and at least one compulsion. None of the subjects had tics. Fifty subjects (83.3%) endorsed at least one stereotypy. Increased anxiety was associated with increased severity of obsessions, but not severity of compulsions or stereotypies.

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 (Nâ¯=â¯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 (Nâ¯=â¯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.

BACKGROUND: Problematic Use of the Internet (PUI) is a considerable issue of the modern era, but its risk factors are still poorly understood. Impulsivity and obsessive-compulsive symptoms have been associated with PUI, but this relationship is still debated. In this article we focus on the relationships of PUI with obsessive-compulsive and impulsive symptoms in a cohort of Italian young adults, in order to identify possible vulnerability factors for PUI. METHODS: A sample of 772 Italian individuals aged 18-30 (mean age 23.3 ± 3.3 years old; 38% males and 62% females) was assessed via online survey using the Internet Addiction Test (IAT), the Mini International Neuropsychiatric Interview (MINI) Screen, the Padua Inventory-Washington State University Revision (PI-WSUR) and the Barratt Impulsiveness Scale (BIS-11). RESULTS: Ninety-seven subjects (12.6% of the sample) reported IAT scores at risk for PUI. PUI participants reported higher levels of impulsivity, obsessive-compulsive symptoms and a higher burden of co-occurrent psychiatric symptoms. In a logistic regression model, obsessional impulses to harm (OR = 1.108, p < 0.001), attentional impulsivity (OR = 1.155, p < 0.001) and depressive symptomatology (OR = 1.246, p = 0.012) had significant association with PUI. Finally, higher severity of PUI has been associated with manic/psychotic symptoms and with attentional impulsivity. CONCLUSIONS: Our findings confirmed the role of impulsivity in PUI, while also underling the association of obsessional impulses with this pathological behavior. We could hypothesize a trigger role of obsessive impulses for the engagement in PUI, together with factors as negative affective states. Further research is needed with respect to more severe forms of PUI, also for establishing tailored interventions.

OBJECTIVE: Some cognitive models of obsessive-compulsive disorder (OCD) posit that intrusions exist on a continuum with obsessions; others consider that they may be unrelated phenomena that differ in the context where they occur. We aimed to examine and compare, at two different moments, the context of the occurrence of intrusions and obsessions. METHOD: Sixty-eight patients with OCD completed an interview appraising their most upsetting obsession and intrusion. RESULTS: At their onset, the obsessions/intrusions were associated with experiencing negative emotional states and life events, and they were more likely to appear in "inappropriate" contexts. The context of the obsessions/intrusions differed the last time they were experienced. Autogenous obsessions/intrusions occurred more frequently in contexts with an indirect link. CONCLUSIONS: The context distinguishes between intrusions and obsessions, not when they emerge, but when the obsession is already established. The results support that there is a continuum or progression from intrusions to obsessions.

Earworms refer to catchy tunes that run repeatedly through a person's mind. Empirical literature regarding earworms is scant; however, some researchers have conceptualized the phenomenon as an unwanted intrusion in the context of obsessive-compulsive disorder. The current study expands upon past research by characterizing the experience of earworms and examining associations of earworm-related distress and interference with theoretical constructs of interest, including obsessive beliefs and experiential avoidance. Two hundred forty participants completed an online survey regarding the experience of musical obsessions (e.g., duration, frequency, distress) and related theoretical constructs (e.g., experiential avoidance) of interest. Descriptive results regarding the frequency, duration, and associated distress and interference of earworms are presented. Furthermore, results reveal that experiential avoidance is a unique predictor of earworm-related distress and interference. Results suggest that interference and distress due to earworms may be related to attempts to suppress them. Study conclusions, limitations, and directions for future research are discussed.

OBJECTIVES: The Yale-Brown Obsessive-Compulsive Scale has been considered the gold standard scale to assess obsessive-compulsive disorder severity. Previous studies using exploratory factor analysis and confirmatory factor analysis with this scale showed mixed findings in terms of factor structure and fit of models. Therefore, we used confirmatory factor analysis to compare different Yale-Brown Obsessive-Compulsive Scale models in a large sample aiming to identify the best model fit. METHODS: We assessed adult obsessive-compulsive disorder patients (n = 955) using three measures: Yale-Brown Obsessive-Compulsive Scale severity ratings, the Dimensional Yale-Brown Obsessive-Compulsive Scale and the clinical global impression scale. We tested all factor structures reported by previous studies to investigate which model best fitted the data: one-factor, two-factor, three-factor and their equivalent high-order solutions. We also investigated Yale-Brown Obsessive-Compulsive Scale items correlations with scores from the other measures of obsessive-compulsive disorder severity. RESULTS: Confirmatory factor analysis models presented mediocre to fair goodness-of-fit indexes. Severity items related to resistance to obsessions and compulsions presented low factor loadings. The model with the best fit indexes was a high-order model without obsessive-compulsive disorder resistance items. These items also presented small correlations with other obsessive-compulsive disorder severity measures. CONCLUSION: The obsessive-compulsive disorder field needs to discuss further improvements in the Yale-Brown Obsessive-Compulsive Scale and/or continue to search for better measures of obsessive-compulsive disorder severity.

An extreme overvalued belief is shared by others in a person's cultural, religious, or subcultural group. The belief is often relished, amplified, and defended by the possessor of the belief and should be differentiated from a delusion or obsession. Over time, the belief grows more dominant, more refined, and more resistant to challenge. The individual has an intense emotional commitment to the belief and may carry out violent behavior in its service. Study participants (n = 109 forensic psychiatrists) were asked to select among three definitions (i.e., obsession, delusion, and extreme overvalued belief) as the motive for the criminal behavior seen in 12 randomized fictional vignettes. Strong interrater agreement (kappa = 0.91 [95% CI 0.83-0.98]) was seen for vignettes representing extreme overvalued belief. Vignettes representing delusion and obsession also had strong reliability (kappa = 0.99 for delusion and 0.98 for obsession). This preliminary report suggests that forensic psychiatrists, given proper definitions, possess a substantial ability to identify delusion, obsession, and extreme overvalued belief. The rich historical foundation of extreme overvalued belief and this small survey study highlight the benefit of inclusion of "extreme overvalued belief" in future glossaries of the Diagnostic and Statistical Manual.

OBJECTIVE: This study reports clinical characteristic of moderate-severe obsessive-compulsive disorder (OCD) among school students in China. METHODS: We examined 153 patients for the distribution of OCD symptoms using the Yale-Brown Obsessive Compulsive Scale Symptoms Checklist, the severity of anxiety and depression symptoms using the Hamilton Anxiety Scale and the Hamilton Depression Scale-24, respectively, and impairment in learning, family and social functions using the Pediatric Quality of Life Enjoyment and Satisfaction Questionnaire. RESULTS: The number of total OCD, obsession and compulsion symptoms was 6.71 (standard deviation [SD] = 2.25), 3.77 (SD = 1.32) and 2.94 (SD = 1.59), respectively. The incidence of moderate and severe depressive symptoms for junior high school students was significantly higher than for primary and high school students. The number of children and adolescents with OCD increased with age, reaching a peak in the senior high school stage. CONCLUSION: The most common symptoms in children and adolescent OCD patients are miscellaneous obsessions, aggressiveness, religiousness, checking, miscellaneous compulsions, cleaning-washing and repeating. These patients show a relatively high co-occurrence rate of anxiety symptoms and depressive symptoms, which impairs their learning, as well as their family and social functions.

BACKGROUND: Previous research using the Symptom-Checklist-90-Revised (SCL-90-R) has shown that compulsive symptoms in Huntington's disease (HD) occur in 10% to 52% of all cases. The "Hamburger-Zwangsinventar" (HZI), a self-rating questionnaire comprising 188 items, taps into the domain of compulsiveness in greater detail, but has not been used in HD so far. In addition, little is known about the association of obsessive-compulsive symptoms with pre-clinical stages of HD. OBJECTIVE: Comparison of OC symptoms measured by the SCL-90-R and the HZI in pre-HD and HD. METHODS: 29 premanifest mutation carriers (pre-HD) and 40 manifest HD patients completed both questionnaires. Clinical characteristics of HD were rated by using the UHDRS. RESULTS: Compared to data from general population prevalence of OC symptoms were not higher as expected in preHD and only slightly elevated in manifest HD if using HZI. Both instruments detected more OC symptoms in HD patients compared to pre-HD. The SCL-90-R more often detects compulsivity than the HZI. Results of both questionnaires showed correlations to cognition, depression, and disease duration. Compared to findings from OCD patients, there was a subordinate role in the HZI subscale for "washing and cleaning" in HD. CONCLUSIONS: OC symptoms in pre-HD occur not more often than in general population. The HZI appears to be useful for examining OC symptoms in detail in pre-HD and HD. HZI-subscale ratings for washing and cleaning compulsions were less pronounced in HD compared to OCD patients, possibly due to loss of disgust. The SCL-90-R might overestimate OC symptoms in both groups.

OBJECTIVES: The aim of the study was to determine the prevalence of orthorexia nervosa in the population of adolescents and young adults, as well as to determine whether orthorexia is a separate clinical entity, a part of eating disorder or another manifestation of obsessivecompulsive disorder. METHODS: The study group consisted of 864 subjects (599 females and 265 males). The mean age of female participants was 20.21±3.27 years, and of male participants 18.93±3.67 years. As a part of the study, we used a proprietary questionnaire to collect patient data, as well as following diagnostic questionnaires: ORTO-15 by Donini et al. (Polish version validated by Janas-Kozik et al.), EAT-26 by Garner and Garfinkel, and MOCI (Maudsley Obsessive Compulsive Inventory) by Hodgson and Rachman. The results were analysed statistically. RESULTS: 27% of subjects were found to be at risk of orthorexia nervosa (score of 35 was considered a cut-off point). These subjects achieved significantly higher scores in the EAT-26. There were no statistically significant differences in the MOCI scores. The highest risk of orthorexia was observed in subjects aged 13-16 years old (junior secondary school) and the lowest in 16-19-year-olds (senior secondary school). Individuals with suspected orthorexia tended to have significantly higher BMI. Specific analysis of environmental features will be exposed in the next issue. CONCLUSIONS: Orthorexia nervosa is not a separate clinical entity. It does not belong to the OCD spectrum, but meets the criteria of eating disorder spectrum.
