Neurological soft signs as trait markers of a subset of patients with obsessive-compulsive disorder with low insight and altered cognitive abilities

Neurological soft signs (NSS) are subtle motor control impairments that include involuntary movements and abnormalities of motor coordination, sensory integration and lateralization. They engage different brain networks, including the prefrontal networks that support the higher cognitive functions that are dysfunctional in obsessive-compulsive disorder (OCD). This study investigated the relationships between the presence of NSS and patients’ severity of OCD symptoms, insight, and treatment resistance in a sample of 63 patients. Treatment-resistance was assessed considering all the treatments the patients received during the course of their disease. The four dimensions of OCD defined in the dimensional obsessive-compulsive scale were considered. Links between the patients’ cognitive abilities and NSS were assessed using tests targeting specifically the core components of executive functions.As expected, OCD patients displayed more NSS than individually matched control participants. In OCD patients, high NSS scores were associated with poor insight and lower cognitive abilities. Multiple regression analysis identified worse visuospatial working memory, attentional control, and verbal fluency as predictive factors of high NSS scores among cognitive functions. Unexpectedly, the patients displaying symptoms in the contamination/washing dimension displayed less NSS than the other patients. In contrast, neither the severity of OCD symptoms nor long-range treatment resistance was significantly related to patients’ NSS scores. Altogether, our findings suggest that high NSS scores may be a trait marker of a subset of OCD patients with low insight and particularly altered cognitive abilities who would not express the contamination/washing dimension of the pathology.

Determining the Cut-off Scores for the Maudsley Obsessional Compulsive Inventory and the Dimensional Obsessive Compulsive Scale and Reviewing Their Psychometric Properties: Which is More Appropriate for the Evaluation of Obsessive Compulsive Disorder?

Objective: Measurement is essential in psychiatry's clinical and research fields. The cut-off scores of the Maudsley Obsessional Compulsive Inventory (MOCI) and the Dimensional Obsessive Compulsive Scale (DOCS), which are widely used in the evaluation of Obsessive Compulsive Disorder (OCD), have not been determined. Method: DOCS and MOCI were applied to 128 patients with OCD and 124 healthy participants. The psychometric properties of the scales were examined by ROC analysis, confirmatory factor analysis, and Rasch models. Results: The cut-off point has been determined as 25 for the DOCS total score, and 18 for the MOCI. The analysis has been shown that some items in MOCI deteriorated the structure of the scale. In DOCS, it has been shown that almost all scale items are compatible with the scale structure. Conclusion: In this study, the cut-off scores have been calculated for the MOCI and the DOCS, so these two scales have become a more effective and helpful construct. It has been also concluded that the DOCS has more robust psychometric properties than the MOCI.

Rethinking Unacceptable Thoughts: Validation of an Expanded Version of the Dimensional Obsessive-Compulsive Scale

The Dimensional Obsessive-Compulsive Scale (DOCS) is widely used to measure obsessive-compulsive disorder (OCD) severity across four broad symptom dimensions (i.e., contamination, responsibility for harm, unacceptable thoughts, symmetry). Despite its proven utility, there is reason to suspect that the unacceptable thoughts subscale conflates different types of unacceptable thoughts that are meaningfully distinct from one another. In the current study, we first evaluated the psychometric properties of a newly developed DOCS violent and/or aggressive thoughts subscale. We then examined the factor structure, psychometric properties, and diagnostic sensitivity of a seven-factor version of the DOCS that includes the four original DOCS subscales and three more-specific versions of the unacceptable thoughts scale (i.e., sexually intrusive thoughts, violent and/or aggressive thoughts, and scrupulous or religious thoughts). The sample included 329 residential and intensive outpatients, the majority of which had a diagnosis of OCD (75.2%). The new unacceptable thoughts subscales demonstrated convergent and discriminant validity with unique associations between the subscales and depression, suicide, and perceived threat from emotions that were not present in the broader unacceptable thoughts subscale. The seven-factor version of the DOCS demonstrated slightly lower levels of diagnostic sensitivity than the original DOCS. Thus, the four-factor version of the DOCS is recommended for screening purposes. A score of 40 or higher on the seven-factor version of the DOCS best predicted a diagnosis of OCD. Overall, the three additional unacceptable thoughts subscales appear to be distinct factors that have potential value in research and clinical settings.

Cognition in Patients with Schizophrenia: Interplay between Working Memory, Disorganized Symptoms, Dissociation, and the Onset and Duration of Psychosis, as Well as Resistance to Treatment.

In total, 105 patients with schizophrenia were observed. Of these, 66 were women and 39 men. Clinical status was assessed using the Positive and Negative Syndrome Scale (PANSS), Brief Psychiatric Rating Scale (BPRS), Dimensional Obsessive-Compulsive Symptom Scale (DOCS), scale for dissociative experiences (DES) and Hamilton Depression Rating Scale (HAM-D)-cognitive functions using the Luria 10-word test with fixation assessment, reproduction and attention analysis. The clinical evaluation of resistance to the treatment showed that 45 patients were resistant to the ongoing medical treatment and the remaining 60 had an effect from the therapy. Our study showed that, in most patients, we found disorders of working memory and attention. In 69.82% of the patients, we found problems with fixation; in 38.1%, problems with reproduction; and in 62.86%, attention disorders. Conducting a regression analysis showed that memory and attention disorders were mainly related to the highly disorganized symptoms scale, the duration of the schizophrenic process and the dissociation scale. It was found that there was a weaker but significant association between the age of onset of schizophrenia and negative symptoms. In the patients with resistant schizophrenia, much greater violations of the studied parameters working memory and attention were found compared to the patients with an effect from the treatment. Impairments in working memory and attention are severely affected in the majority of patients with schizophrenia. Their involvement is most significant in patients with resistance to therapy. Factors associated with the highest degree of memory and attention impairment were disorganized symptoms, duration of schizophrenia, dissociative symptoms and, to a lesser extent, onset of illness. This analysis gives us the right to consider that the early and systematic analysis of cognition is a reliable marker for tracking both clinical dynamics and the effect of treatment.

Is Acceptance and Commitment Therapy Effective for Any Obsessive-Compulsive Symptom Dimensions?

Acceptance and commitment therapy (ACT) has been recently introduced for treating obsessive-compulsive disorder (OCD). Although there are data supporting the efficacy of ACT, only few studies have investigated the effectiveness of ACT against any obsessivecompulsive (OC) symptom dimension or a specific dimension alone. In total, 64 patients with OCD received an 8-session ACT group program. All measures were evaluated before and after treatment. The Dimensional Obsessive-Compulsive Scale was used to assess OCD severity across the four empirically supported symptom dimensions (i.e., contamination, responsibility for harm, unacceptable thoughts, and symmetry). ACT processes were evaluated using the Acceptance and Action Questionnaire-II (AAQ-II), Acceptance and Action Questionnaire for Obsessions and Compulsions (AAQOC), and Cognitive Fusion Questionnaire. After an 8-week program, there were significant reductions in all four OC symptom dimensions after ACT. The unacceptable thoughts and contamination domains had medium effect size. The responsibility for harm and symmetry dimensions had small effect size. The unacceptable thoughts dimension was significantly correlated with all ACT process measures. The symmetry dimension was significantly correlated with AAQ-OC and AAQ-II scores while the responsibility for harm dimension was correlated with AAQ-II alone. However, the contamination dimension was not associated with any process measures. ACT may be effective for managing all four symptom dimensions with small to moderate effect size. Moreover, depending on the symptom dimension, there may be different relationship patterns between symptom reduction and changes in ACT processes.

The effects of psychological flexibility and resilience on psychopharmacological treatment response in patients with obsessive-compulsive disorder.

Obsessive-compulsive disorder (OCD) is a challenging psychiatric condition to treat. Previous research has explored various aspects of treatment response, but limited attention has been given to the significance of psychological flexibility and resilience. This study aimed to investigate the correlation between psychological flexibility, resilience, and different dimensions of OCD, as well as their role in treatment response specifically concerning OCD symptom sub-dimensions. The study involved 50 OCD patients and 42 healthy individuals as controls. Participants completed the Dimensional Obsessive-Compulsive Scale (DOCS), Acceptance and Action Questionnaire (AAQ-2), and Resilience Scale for Adults (RS). Initial scale scores were compared to post-treatment scores obtained after a 3-month follow-up using pharmacotherapy. The patient group exhibited significantly higher AAQ-2 scores and lower RS scores compared to the control group. During the post-treatment follow-up, a reduction in DOCS and AAQ-2 scores was observed, along with an increase in RS scores. The impact of differences in AAQ-2 and RS scores on the change in DOCS total scores was analyzed using mixed model linear regression analysis. The results showed a statistically significant effect of changes in AAQ-2 and RS sub-dimension scores on the change in DOCS total scores. The findings highlight the importance of flexibility and resilience in influencing treatment response among patients with OCD. When conventional pharmacotherapy and psychotherapy approaches prove insufficient, interventions focused on enhancing flexibility and resilience may contribute to improved treatment outcomes.

Dimensional Assessment of Depression and Anxiety in a Clinical Sample of Adults With Chronic Tic Disorder.

Among adults with Tourette syndrome, depression and anxiety symptoms are widely prevalent and consistently associated with poor quality of life. Important knowledge gaps remain regarding mood and anxiety dimensions of the adult Tourette syndrome phenotype. Taking a dimensional approach, this study sought to determine the prevalence, severity, and clinical correlates of depression and anxiety symptoms in a clinical sample of adults with Tourette syndrome and other chronic tic disorders. A retrospective chart review was conducted of all adults with a chronic tic disorder presenting to a tertiary care Tourette syndrome clinic between December 2020 and July 2022. Information extracted during chart review included data from scales administered as part of routine care: Quality of Life in Neurological Disorders (Neuro-QoL) Depression Short Form, Neuro-QoL Anxiety Short Form, Adult Attention-Deficit/Hyperactivity Disorder Self-Report Screening Scale, Dimensional Obsessive-Compulsive Scale, and Yale Global Tic Severity Scale. Relationships between variables were examined by conducting between-group, correlation, and multivariable regression analyses. Data from 120 adult patients with a chronic tic disorder (77 men and 43 women) were analyzed. Neuro-QoL Anxiety scores were elevated in 66% of the cohort; Neuro-QoL Depression scores were elevated in 26%. Neuro-QoL Anxiety scores were significantly higher than general population norms, whereas Neuro-QoL Depression scores were not. After adjustment for covariates, depressive and anxiety symptom severity scores were significantly associated with each other and with obsessive-compulsive disorder symptom severity but not with tic severity. Sex-based differences emerged in the analyses. Among adults with chronic tic disorder, anxiety symptoms were more prevalent and severe than depressive symptoms, co-occurring psychiatric symptoms were more tightly linked with each other than with tic severity, and sex-based differences were evident.

Characteristics and predictors of family accommodation in Turkish individuals with obsessive-compulsive disorder.

Family accommodation (FA) is associated with disease severity and response to treatment rates in patients with obsessive-compulsive disorder (OCD) and is therefore particularly important in this patient group. This study investigated the structure of FA and associated factors in a Turkish society sample. The study was carried out with 92 patients diagnosed with OCD for at least 1 year, who applied to Alanya ALKU Training and Research Hospital psychiatry outpatient clinic between February 2021 and March 2022. Sociodemographic data form, Family Accommodation Scale-Patient Form (FAS-PF), Dimensional Obsessive-Compulsive Scale (DOCS), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI) and Acceptance and Action Questionnaire (AAQ-II) were applied to all of the cases. Relatives filled out the Sociodemographic Data. The mean age of the patients was 32.11 ± 11.56 years. Sixty-nine (75%) of the patients were women. Fifty (54.3%) patients weremarried. All participants reported FA behavior at least once in the previous week. FA exhibited no significant variation by sex (p = 0.679)or marital status (p = 0.256). Significant positive correlation was determined between DOCS-T (r = 0.370, p < 0.001), AAQ-II (r = 0.261, p = 0.013), BDI (r = 0.235, p = 0.024) and BAI (r = 0.342, p = 0.001) scores and the FAS-PF. In the regression analysis, only OCD disease severity predicted FA [(β = 0.295, p = 0.036, 95% confidence interval (95% CI) = 0.02 to 0.55)]. Higher FA scores were obtained in this study (23.93 ± 15.28) compared to previous research in Western societies (14.3 ± 15.2). Clinicians should consider FA in the examination of OCD patients. High FA values for both frequency and severity suggestthat interventions directed toward FA may be associated with more positive outcomes in outpatient Turkish patients with OCD.

Validation of the Chinese version of the dimensional obsessive-compulsive scale (DOCS) in Chinese clinical samples

• The Chinese version of the Dimensional Obsessive-Compulsive Scale (C-DOCS) is a reliable and valid assessment tool for Chinese OCD patients. • It has good internal consistency, test-retest reliability and convergent and discriminant validity. • It has a robust four-factor model, with evidence of a second-order factor. • It can be applied to Chinese OCD patients in clinical settings. • Future research should work on the dimensionality of OCD.

Development and validation of the Inventory of Depression and Anxiety Symptoms–II—German version.

The expanded version of the Inventory of Depression and Anxiety Symptoms (IDAS-II) is a 99-item self-report measure containing 18 nonoverlapping dimensional scales assessing symptoms of depression, anxiety, and mania. The aim of this study was to develop and validate a German adaptation of the IDAS-II. Participants from a community sample (N = 1,054) completed the IDAS-II (German version). In addition, part of the sample (N = 550) completed a series of additional measures of depression (Patient Health Questionnaire-9, WHO-Five Well-Being Index, Symptom Checklist-90 Revised-Short Version) and anxiety disorders (Generalized Anxiety Disorder Scale-7, Fear of Negative Evaluation Scale-5, Dimensional Obsessive-Compulsive Scale, The International Trauma Questionnaire). We conducted item-level confirmatory factor analyses (CFA) separately for the 15 nonsaturated IDAS-II scales, which confirmed unidimensionality. McDonald's ω indicated good internal consistency (ω > .8) of all symptom scales except Euphoria (ω = .751) and Ordering (ω = .728). A CFA of the IDAS-II scales, based on exploratory results by Watson et al. (2012), confirmed a three-factor model of "Distress," "Obsessions/Fear," and "Positive Mood." Correlational analyses with additional symptom measures supported the convergent and discriminant validity of the IDAS-II scales. The IDAS-II (German version) allows for a reliable assessment of the severity of depression, anxiety, and bipolar symptoms and is one of the first clinical measures for German-speaking samples that is consistent with the Hierarchical Taxonomy of Psychopathology (HiTOP).

Obsessive-compulsive symptoms among the general population during the first COVID-19 epidemic wave in Italy

This study investigated obsessive-compulsive symptoms (OCS) in the Italian general population during the initial stage of the pandemic and the impact of COVID-19 related potential risk factors. A web-based survey was spread throughout the internet between March 27th and April 9th, 2020. Twenty thousand two hundred forty-one individuals completed the questionnaire, 80.6% women. The Dimensional Obsessive-Compulsive Scale (DOCS) was included to assess the severity of the obsessive-compulsive symptom domains. Further, selected outcomes were depression, anxiety, insomnia, perceived stress, and COVID-19 related stressful life events. A panel of logistic or linear regression analyses was conducted to explore the impact of COVID-19 related risk factors, socio-demographic variables, and mental health outcomes on OCS. A total of 7879 subjects (38,9%) reported clinically relevant OCS. Specifically, more than half of the sample (52%) reported clinically relevant symptoms in the Contamination domain, 32.5% in the Responsibility domain, 29.9% in the Unacceptable thoughts domain, and 28.6 in the Symmetry/Ordering domain. Being a woman was associated with OCS, except for Symmetry/Ordering symptoms. A lower education level and younger age were associated with OCS. Moreover, depression, anxiety, perceived stress symptoms, insomnia, and different COVID-19 related stressful events were associated with OCS. We found high rates of OCS, particularly in the contamination domain, in the Italian general population exposed to the first COVID-19 epidemic wave and COVID-19 related risk factors. These findings suggest the need to investigate further the trajectories of OCS in the general population along with the long-term socio-economic impact of the pandemic.

Increases in symptoms associated with obsessive-compulsive disorder among university students during the COVID-19 pandemic

Objective The long-term consequences of the COVID-19 pandemic on college students’ mental health remains unknown. The current study explored self-reported Obsessive-Compulsive symptomatology among college student cohorts from pre-, peak-, and later-pandemic time points. Participants Undergraduate college students (N = 524) who volunteered for course credit. Methods Self-report responses on the Dimensional Obsessive-Compulsive Scale (DOCS), which includes subscales for contamination, unacceptable thoughts, harm responsibility, and symmetry, were collected from November 29, 2016 through April 27, 2021 and assessed for differences between the pre-, peak-, and later-pandemic cohorts. Results Peak-pandemic responders reported higher symptomatology for contamination and unacceptable thoughts compared to pre-pandemic responders (and for pre- vs. later-pandemic for contamination), with no significant effects for symmetry or harm responsibility. Conclusions Although the longer-term consequences of the COVID-19 pandemic on students remains unknown, a greater shift in college mental health services from prevention to assessing and addressing more immediate challenges may be necessary.

Abstract- Poster

Background:Shame is a painful emotion which is experienced when a person judges oneself negatively and guilt is associated with negative judgment of one’s behavior. The clinical experience and literature suggests that persons with OCD experience both these emotions. Shame in particular is found to be as a barrier in treatment.Aim:The present study aims at studying feelings of shame and guilt and their emotion regulation in relation with dimensions of OCD. Material and Method: 30 persons with OCD will be taken from OPD of Institute of Mental Health and Hospital, Agra. Following tools will be individually administered on the participants. (a) State Shame and Guilt Scale (Marschall, Saftner, & Tangney, 1994) (b) Dimensional Obsessive-Compulsive Scale (Abramowitz et al. 2010) (c) Emotion Regulation Questionnare (Gross & John, 2003).Results:The data will be subjected to correlational analysis and the results will be shared.

The effect of COVID-19 pandemic on mental health and quality of life in the Athens area - Greece.

This study examines the associations of the COVID -19 pandemic stressors with mental health and quality of life (QoL) of the general population in different demographic areas of Athens. The random sample of the study consisted of 602 participants, 389 (64,6%) women and 213 (35,4%) men residing in Attica (Greece). It was conducted with telephone interviews during the first wave of the pandemic. The instruments used were: World Health Organization Quality of Life Instrument (WHOQOL-BREF), Depression Anxiety Stress Scale (DASS - 21), Body Vigilance Scale (ΒVS), Dimensional Obsessive-Compulsive Scale (Category 1: contamination obsessions -decontamination compulsions) (DOCS) and a set of socio-demographic data and questions on stressors related to the COVID-19 outbreak. A range of statistical analyses were used, including descriptive statistics, examination of the questionnaires' internal consistency, calculating Cronbach's alpha coefficient, as well as multiple linear regression analyses with dependent variables the WHOQOL-BREF, DASS-21, DOCS, and BVS scales. According to the results of our study: a) The greater the extent of negative emotions due to the pandemic and the imposed restrictive measures, such as worry and fear, the higher the score of depression, anxiety, stress, obsessive-compulsive symptomatology, body vigilance and the lower the scores of the WHOQOL domains (Physical Health, Psychological Health, Social Relationships, Environment), b) the fear of being contaminated by the virus seems to have intensified depression-anxiety-stress (DASS-21), obsessive-compulsive (DOCS) and hypochondriacal (BVS) symptomatology. c) The independent variables of depression, stress and anxiety and obsessive - compulsive and hypochondriacal symptomatology were negatively associated with QoL d) The most vulnerable groups in terms of QoL and mental health indicators in our study were those with psychiatric or/and physical illness, the elderly, the unemployed during the lockdown period, those with low educational/ socioeconomic status and those living alone. In conclusion, the negative emotions associated with the COVID-19 outbreak and the imposed restrictive measures had a serious impact on mental health and QoL of the population. This and other similar findings should be taken into account by authorities and decision-makers to prevent and deal with the effects of the pandemic. Unfortunately, the COVID-19 pandemic is still continuing and the imposition of new restrictive measures is considered. This increases the relevance of research like the one presented here.

Relationship between Obsessive-Compulsive Symptoms and Anxiety Levels during the COVID-19 Pandemic in Healthcare Professionals vs. Non-Healthcare Professionals

The present study investigated the effect of the COVID-19 pandemic on anxiety levels, contamination and responsibility/control obsessions and associated OC behaviors in healthcare versus non-healthcare professionals. The study also aimed to examine the relationship between anxiety levels and obsessive-compulsive (OC) symptom levels, gender, age, educational level, and personal and family history of chronic diseases. The 664 participants included 395 (59.5%) men and 269 (40.5%) women and comprised 180 (27.1%) healthcare professionals and 484 (72.9%) non-healthcare professionals. The survey included three data collection tools: (i) Sociodemographic data form, (ii) Beck Anxiety Inventory (BAI), and (iii) the Dimensional Obsessive-Compulsive Scale Abriged (DOCS-A) pre- and post-pandemic forms. The BAI scores established a moderate positive correlation with post-pandemic DOCS-A total scores and a weak positive correlation with pre-pandemic DOCS-A total scores (<i>p</i> < 0.001 for both). Pre- and post-pandemic DOCS-A total and subdimension scores were significantly higher in women than in men (<i>p</i> < 0.05). Participants with a personal history of chronic diseases had higher BAI and DOCS-A scores compared to participants with no such history (<i>p</i> < 0.001 and <i>p</i> < 0.001, respectively). The results indicated a significant increase in OC symptoms during the pandemic period compared to the pre-pandemic period and a moderate correlation between the anxiety levels and OC symptom severity. It was also revealed that female gender and personal or family history of chronic diseases posed a higher risk for the increase in anxiety and OC symptoms and healthcare professionals had a higher risk of developing anxiety symptoms compared to non-healthcare professionals.

Screening for Perinatal OCD: A Comparison of the DOCS and the EPDS.

Screening for perinatal-occurring obsessive-compulsive disorder (OCD) is rare. We sought to evaluate the Dimensional Obsessive-Compulsive Scale (DOCS) as a screening tool for perinatal OCD and compare the screening accuracy of the DOCS with the commonly recommended Edinburgh Postnatal Depression Scale (EPDS). English-speaking, pregnant individuals aged 19+ (N = 574) completed online questionnaires and diagnostic interviews to assess for OCD prenatally and twice postpartum. The DOCS total score demonstrated the highest level of accuracy. Neither the EPDS-Full nor the three-item Anxiety subscale of the EPDS (EPDS-3A) met the criteria of a sufficiently accurate screening tool for OCD at any of the assessment points. Findings provide support for the DOCS as a screening tool for perinatal OCD and indicate a need for disorder-specific screening for perinatal anxiety and their related disorders (AD). Generalizability of findings is limited to Canada only. Future research would benefit from comparisons with measures of perinatal OCD (e.g., the Perinatal Obsessive-Compulsive Scale).

Cross-disorder comparison of sensory over-responsivity in chronic tic disorders and obsessive-compulsive disorder

BackgroundSensory over-responsivity (SOR) refers to excessively intense and/or prolonged behavioral responses to environmental stimuli typically perceived as non-aversive. SOR is prevalent in several neurodevelopmental disorders, including chronic tic disorders (CTDs) and obsessive-compulsive disorder (OCD). Few studies have examined the extent and clinical correlates of SOR across disorders, limiting insights into the phenomenon's transdiagnostic clinical and biological relevance. Such cross-disorder comparisons are of particular interest for CTDs and OCD given their frequent co-occurrence. ObjectiveWe sought to compare the magnitude of SOR between adults with CTD and adults with OCD and to identify the clinical factors most strongly associated with SOR across these disorders. MethodsWe enrolled 207 age- and sex-matched participants across four diagnostic categories: CTD without OCD (designated “CTD/OCD-”; n = 37), CTD with OCD (“CTD/OCD+”; n = 32), OCD without tic disorder (“OCD”; n = 69), and healthy controls (n = 69). Participants completed a self-report battery of rating scales assessing SOR (Sensory Gating Inventory, SGI), obsessive-compulsive symptoms (Dimensional Obsessive-Compulsive Scale, DOCS), inattention and hyperactivity (Adult ADHD Self-Report Screening Scale for DSM-5, ASRS-5), anxiety (Generalized Anxiety Disorder-7), and depression (Patient Health Questionnaire-9). CTD participants were also administered the Yale Global Tic Severity Scale (YGTSS). To examine between-group differences in SOR, we compared SGI score across all groups and between pairs of groups. To examine the relationship of SOR with other clinical factors, we performed multivariable linear regression. ResultsCTD/OCD-, CTD/OCD+, and OCD participants were 86.7%, 87.6%, and 89.5%, respectively, more likely to have higher SGI total scores than healthy controls. SGI total score did not differ between CTD/OCD-, CTD/OCD+, and OCD groups. In the regression model of log-transformed SGI total score, OCD diagnosis, DOCS score, and ASRS-5 score each contributed significantly to model goodness-of-fit, whereas CTD diagnosis and YGTSS total tic score did not. ConclusionSOR is prevalent in adults with CTD and in adults with OCD but does not significantly differ in magnitude between these disorders. Across CTD, OCD, and healthy control adult populations, SOR is independently associated with both obsessive-compulsive and ADHD symptoms, suggesting a transdiagnostic relationship between these sensory and psychiatric manifestations. Future cross-disorder, longitudinal, and translational research is needed to clarify the role and prognostic import of SOR in CTDs, OCD, and other neurodevelopmental disorders.

Are “not just-right experiences” trait and/or state marker for obsessive-compulsive disorder?

Background and objectives“Not Just Right Experiences” (NJREs) are common phenomena in individuals with obsessive-compulsive disorder (OCD), involving a feeling that something is ‘not right’ or as it should be. Some evidence suggests that NJREs may be an endophenotypic marker. This study aimed to investigate whether NJREs are a trait marker present in unaffected first-degree relatives of OCD and/or a state marker associated with obsessive-compulsive symptoms. MethodsThe study included 51 OCD patients, 47 first-degree relatives and 45 healthy controls. Not Just Right Experiences Questionnaire Revised (NJRE-QR), Frost Multidimensional Perfectionism Scale (FMPS), and Dimensional Obsessive-Compulsive Scale (DOCS) were administered to the participants. ResultsThere was no significant difference between the first-degree relatives and healthy controls in respect of NJRE-total and NJRE-severity scores. In the hierarchical regression analysis performed in OCD group, the severity of NJREs were associated with the severity of obsessive-compulsive symptoms and the 'doubts about actions' dimension of perfectionism. ConclusionsThis is the first study investigating NJREs in relatives of a clinical OCD group. The results of this study support the view that NJREs are state markers for OCD.

An examination of the sentence task through in-person and online administrations

The Sentence Task (Rachman et al., 1996) has respondents write “I hope ___ is in a car accident,” filling the blank with a loved one. Used in many laboratory-based studies of Thought-Action Fusion (TAF), it is unclear whether the induced distress is TAF-specific. Four studies (total N = 405 undergraduates) examined the extent to which Task-induced anxiety is empirically correlated with conceptually relevant self-report measures. We also explored using the Task in an online format; two studies were in-person, two were online. First, completion of the Task resulted in significant (ps < .001) increase in anxiety in all four studies (ds ranged from 0.52 to 0.86). However, in three of the four studies, there was no significant correlation (ps > .05) between the magnitude of pre-to post-Task anxiety change and baseline measures (Thought-Action Fusion Scale, Dimensional Obsessive-Compulsive Scale). This suggests that the Task-induced anxiety may not be specific to TAF. Second, there were no significant mean-level differences for any variables whether assessed in-person vs. online. However, Task refusal was significantly higher for online (21.2%, 24.1%) vs. in-person (5.4%, 6.0%) administrations. Findings contribute to a better understanding of the Task and offer mixed support for use in an online format.

Predictors of obsessive-compulsive symptomology: mind wandering about the past and future.

PurposeObsessive and compulsive tendencies are known to occur in the general population and involve worry around specific concerns (obsessions) and an urge to resolve the concern with thoughts or behaviours (compulsions). Spontaneous, but not deliberate, mind wandering experiences (when attention turns to internal mentation), have been found to predict obsessive– compulsive tendencies [Seli, P., Risko, E.F., Purdon, C. & Smilek, D. (2017). Intrusive thoughts: linking spontaneous mind wandering and OCD symptomatology. Psychological Research, 81, 392–398. 10.1007/s00426-016-0756-3]. Recent cognitive theory suggests a particular role for future-oriented spontaneous thought in obsessive–compulsive (OC) symptoms. Thus, we hypothesised that future-oriented rather than past-oriented spontaneous mind wandering would predict OC symptoms, such that more future-oriented mind wandering would be associated with increases in OC symptoms.MethodsIn an online survey design (nonclinical sample of 104 adults), participants completed three measures: Mind wandering: Spontaneous (MW-S) and Deliberate (MW-D) (Carriere, Seli & Smilek, 2013); Involuntary Autobiographical Memory Inventory (Berntsen, Rubin & Salgado, 2015); and Dimensional Obsessive–Compulsive Scale (DOCS) (Abramowitz et al., 2010). We adopted a linear regression approach to examine our hypotheses.ResultsWe provided the first replication of the finding that OC symptoms are predicted by the frequency of spontaneous (but not deliberate) mind wandering, with an underlying positive relationship. Additionally, we found that temporality of spontaneous thought had different predictive effects as a function of the dimension of OC symptoms (i.e., responsibility, unacceptable thoughts, need for symmetry/completeness). ConclusionsWe found moderate support for our temporality hypothesis, which highlights how the construct of temporality can add to our understanding of OC symptoms. The present study also adds to recent conceptual debates regarding mind wandering. We suggest new cognitive and methodological approaches to enhance the understanding of obsessive–compulsive disorder, opening new avenues for clinical and experimental research.
