Background/Objective 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. Method 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. Results 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. Conclusions UMIs are a common phenomenon across different cultural contexts and operate transdiagnostically across clinically different disorders.

Background/ObjectiveUnwanted mental intrusions (UMIs) are the normal variants of obsessions in Obsessive-Compulsive Disorder (OCD), preoccupations about defects in Body Dysmorphic Disorder (BDD), images about illness in Hypochondriasis (HYP), and thoughts about eating in Eating Disorders (EDs). The aim was to examine the similarities and differences in the functional links of four UMI contents, adopting a within-subject perspective. Method: 438 university students and community participants (Mage = 29.84, SD = 11.41; 70.54% women) completed the Questionnaire of Unpleasant Intrusive Thoughts (QUIT) to assess the functional links (emotions, appraisals, and neutralizing/control strategies) of the most upsetting UMIs with OCD, BDD, HYP and EDs-contents. Results: HYP-related intrusions caused the highest emotional impact, OCD-related intrusions were the most interfering, and EDs-related intrusions interfered the least. The four UMI were equally ego-dystonic. Women appraised OCD-related intrusions more dysfunctionally, but men appraised the four intrusive contents similarly. All UMI instigated the urge to “do something”, to keep them under control and/or neutralizing them. Conclusions: Similarities among the functional links of intrusions related to OCD, BDD, HYP and EDs contents support their transdiagnostic nature and they might contribute to understanding common factors in these disorders.

Mobile health apps increase the accessibility of cognitive-behavioral–based interventions before, during, or following treatment. GGOC is a mobile app designed to challenge maladaptive beliefs in obsessive-compulsive disorder (OCD). This single-case study assesses the usefulness of GGOC as a relapse prevention tool for OCD. The patient was a 26-year-old woman with severe contamination and washing/cleaning OCD symptoms (Y-BOCS = 33). GGOC was used for relapse prevention following CBT treatment. The patient completed 47 levels dedicated to OCD-relevant maladaptive beliefs. Before and after GGOC, the Y-BOCS, Obsessive-Compulsive Inventory (OCI-R), Obsessive Beliefs Questionnaire (OBQ-20), and Depression subscale of the Depression, Anxiety, Stress Scale were completed. The OBQ-20 and OCI-R scores decreased from pre- to post-GGOC. The Y-BOCS decreased from 7 pre-GGOC to 2 post-GGOC. Findings support the efficacy of GGOC as a relapse prevention tool for individuals with OCD, and its contribution to maintaining gains after CBT.

Abstract. The objective of a transdiagnostic perspective in psychopathology is to better understand the commonalities among clinically different mental disorders on the basis of a set of shared etiopathogenic dimensions and processes. Unwanted intrusive cognitions (UI) and their functional consequences had been proposed as symptom dimensions in Obsessive-Compulsive Disorder (OCD), Body Dysmorphic Disorder (BDD), Hypochondriasis (HYP) and Eating Disorders (EDs). In this article, we review the empirical data about the putative transdiagnostic nature of UI and their functional consequences in the four mentioned disorders. Firstly, the results about the universality and dimensionality of UI with contents of each disorder are reviewed. Secondly, data about UI as common symptom dimensions in OCD and EDs are presented. Finally, we offer information about our current research about the hypothetical transdiagnostic nature of UI with obsessional, dysmorphic, hypochondriac, and eating-disorders contents.Keywords: Mental intrusions; transdiagnostic; obsessive-compulsive disorder; body dysmorphic disorder; hypochondriasis; eating disorders.Resumen. El propósito de adoptar un enfoque transdiagnóstico en psicopatología es comprender las comunalidades entre trastornos mentales clínicamente diferentes sobre la base de un rango de dimensiones y procesos etiopatogénicos compartidos. Las intrusiones mentales no deseadas (IM) y sus consecuencias funcionales se han propuesto como dimensiones de síntomas en el Trastorno Obsesivo-Compulsivo (TOC), el Trastorno Dismórfico Corporal (TDC), la Hipocondría (HIP) y los Trastornos Alimentarios (TA). Este artículo resume y actualiza los datos disponibles sobre el potencial valor transdiagnóstico de las intrusiones mentales y sus consecuencias funcionales en los cuatro trastornos mencionados. Se presentan, primero, los resultados sobre la universalidad y dimensionalidad de IM con contenidos característicos de cada trastorno; segundo, los datos sobre las IM como dimensiones de síntomas comunes en el TOC y los TA; por último, se aporta información sobre una investigación propia cuyo objetivo es poner a prueba la hipótesis del carácter transdiagnóstico de IM obsesivas, dismórficas, hipocondríacas y alimentarias.Palabras clave: Intrusiones mentales; transdiagnóstico; trastorno obsesivo-compulsivo; trastorno dismórfico corporal; hipocondría; trastornos alimentarios. IntroducciónFrente a la caracterización categorial de los trastornos mentales en los sistemas de diagnóstico psiquiátrico, que establecen características únicas y específicas de y para cada trastorno, surge a principios de este siglo el denominado enfoque transdiagnóstico de la psicopatología (Sandín, 2012). Su objetivo es identificar los procesos disfuncionales nucleares que subyacen a trastornos mentales que, aun siendo diferentes en su manifestación clí-nica, mantienen tasas de comorbilidad más elevadas de lo que cabría esperar por azar, se ajustan bien a modelos explicativos similares, y responden a tratamientos a menudo idénticos.

Positive emotion regulation (ER) strategies may contribute to the development and maintenance of generalized anxiety disorder (GAD) and depression; nonetheless, the underlying and transdiagnostic mechanisms are still unknown. To examine: 1) the mediating role of positive ER strategies in the relationship between ER deficits and experiential avoidance in GAD and depression symptoms; 2) differences in positive ER strategies among participants with elevated symptoms of GAD, depression, depression comorbid with GAD, and a nonclinical sample. 532 Tehran University students completed questionnaires assessing experiential avoidance, deficits in ER, positive ER strategies (dampening, positive rumination), and GAD and depression symptoms. Differences were assessed in four groups: GAD, depression, depression comorbid with GAD, and nonclinical. Data were analysed with path analysis and MANCOVA. Dampening and positive rumination mediated the relationship between deficits in ER and experiential avoidance in participants with depression and GAD symptoms. As for the between groups comparisons, the comorbid group obtained the highest scores on dampening and the nonclinical group the lowest. By contrast, nonclinical participants had the highest scores on positive rumination, whereas the comorbid group had the lowest. Positive ER strategies might be transdiagnostic variables. Dampening was more associated with psychopathology than positive rumination, suggesting that this strategy could be more clearly considered a transdiagnostic factor. Future studies with clinical samples must support this suggestion.
