Unwanted mental intrusions (UMIs), typically discussed in relation to Obsessive-Compulsive Disorder (OCD), are highly prevalent, regardless of the specific nationality, religion, and/or cultural context. Studies have also shown that UMIs related to Body Dysmorphic Disorder (BDD), Illness anxiety/Hypochondriasis (IA-H), and Eating Disorders (EDs) are commonly experienced. However, the influence of culture on these UMIs and their transdiagnostic nature has not been investigated. Participants were 1,473 non-clinical individuals from seven countries in Europe, the Middle-East, and South America. All the subjects completed the Questionnaire of Unpleasant Intrusive Thoughts, which assesses the occurrence and discomfort of four UMI contents related to OCD, BDD, IA-H, and EDs, and symptom questionnaires on the four disorders. Overall, 64% of the total sample reported having experienced the four UMIs. The EDs intrusions were the most frequently experienced, whereas hypochondriacal intrusions were the least frequent but the most disturbing. All the UMIs were significantly related to each other in frequency and disturbance, and all of them were associated with clinical measures of OCD, BDD, IA-H, and EDs. UMIs are a common phenomenon across different cultural contexts and operate transdiagnostically across clinically different disorders.

Background:The mechanisms and triggers of the attentional bias in social anxiety are not yet fully determined, and the modulating role of personality traits is being increasingly acknowledged.Aims:Our main purpose was to test whether social anxiety is associated with mechanisms of hypervigilance, avoidance (static biases), vigilance-avoidance or the maintenance of attention (dynamic biases). Our secondary goal was to explore the role of personality structure in shaping the attention bias.Method:Participants with highvslow social anxiety and different personality structures viewed pairs of faces (free-viewing eye-tracking task) representing different emotions (anger, happiness and neutrality). Their eye movements were registered and analysed for both whole-trial (static) and time-dependent (dynamic) measures.Results:Comparisons between participants with high and low social anxiety levels did not yield evidence of differences in eye-tracking measures for the whole trial (latency of first fixation, first fixation direction, total dwell time), but the two groups differed in the time course of overt attention during the trial (dwell time across three successive time segments): participants with high social anxiety were slower in disengaging their attention from happy faces. Similar results were obtained using a full-sample, regression-based analysis.Conclusion:Our results speak in favour of a maintenance bias in social anxiety. Preliminary results indicated that personality structure may not affect the maintenance (dynamic) bias of socially anxious individuals, although depressive personality structures may favour manifestations of a (static) hypervigilance bias.

Worry is a common phenomenon with people who anticipate and want to be prepared for future events. Pathological worry, however, is not limited to anticipating potentially dangerous events, but it is applied to small daily events, too. This kind of worry is perceived as uncontrollable, and it is strongly associated with catastrophism. The Penn State Worry Questionnaire (PSWQ) was developed to assess pathological worry. Despite its excellent psychometric characteristics, its internal structure is still controversial. The combination of regular and reversed items and certain methodological considerations may account for the discrepancies in the results of previous investigations. With the aim to analyze worry in Portugal and the psychometric properties of the PSWQ, for the present study, methodological options were considered in order to minimize previous problems. A sample of 558 Portuguese community participants took part in this study. Exploratory and Confirmatory Factor Analysis were performed with two independent random subsamples. The results showed the unidimensionality of PSWQ and the psychometric adequacy of both the full, 16-item version and a reduced, 11-item version (without reversed scored items). Normative data are presented, the suitability of both versions is discussed, and the authors conclude by encouraging the use of the reduced, 11-item version of the PSWQ in applied settings.

Unwanted mental intrusions (UMIs) with contents related to Obsessive-Compulsive Disorder (OCD), Body Dysmorphic Disorder (BDD), Illness Anxiety Disorder (IAD), and Eating Disorders (EDs) are highly prevalent, independently of the cultural and/or social context. Cognitive-behavioral explanations for these disorders postulates that the escalation from common UMIs to clinically relevant symptoms depends on the maladaptive consequences (i.e., emotions, appraisals, and control strategies) of experiencing UMIs. This study examines, from a cross-cultural perspective, the cognitive-behavioral postulates of the maladaptive consequences of having UMIs. Non-clinical 1,473 participants from Europe, the Middle-East, and South America completed the Questionnaire of Unpleasant Intrusive Thoughts to assess the maladaptive consequences of experiencing highly disturbing OCD, BDD, IAD, and EDs-related UMIs. Findings revealed main effects for both the country and the consequences associated with the four UMI contents. Interaction effects between the consequences of each UMI content and the sample location were also observed. Cognitive-Behavioral models for OCD, BDD, IAD, and EDs should be implemented along with socio-cultural variables that increase the understanding of the role of these variables in the phenomenology of UMIs and their associated consequences.

Cognitive models of obsessive-compulsive disorder attribute a causal role to maladaptive beliefs. To test this hypothesis, we manipulated Overimportance of Thoughts (OT) beliefs and experimentally evaluated their effect on the response to an induced aggressive impulse. Eighty-five participants completed a battery of self-report instruments assessing obsession symptoms, thought control, affectivity and obsessive beliefs, and were then randomly assigned to two conditions. In the experimental condition participants read a scientific abstract on the importance of thought control whilst those in the control condition read a neutral All participants identified a loved person and imagined feeling the impulse to stab this person, then completed again OT beliefs measures (Overimportance of Thought, Moral-Thought Action Fusion and Thought Action Fusion Likelihood). The Moral component of the Thought Action Fusion was reduced by reading a brief text about the possibility and desirability of thought control. However, experimentally induced changes in beliefs did not yield differences in the intrusiveness of the aggressive impulse. Some beliefs can be modified through a single session in which information similar to what could be obtained in quotidian life is provided.
