RESUMEN
Peer victimization contributes to the development of major depressive disorders (MDDs). While previous studies reported differentiated peripheral physiological responses in peer-victimized individuals with depression, little is known about potential alterations of cortical event-related potentials (ERPs) in response to social stimuli in depressive patients with a history of peer victimization. Using a social condition paradigm, the present study examined whether peer victimization alters conditioned cortical responses to potentially threatening social stimuli in MDD patients and healthy controls. In the task, we studied ERPs to conditioned stimuli (CSs), i.e. still images of faces, that were coupled to unconditioned socially negative and neutral evaluative video statements. Peer victimization was related to more pronounced P100 amplitudes in reaction to negative and neutral CSs. Attenuated P200 amplitudes in peer-victimized individuals were found in response to negative CSs. Cortical responses to CSs were not influenced by a diagnosis of MDD. The results suggest altered responsiveness to interpersonal information in peer-victimized individuals. Facilitated early processing of social threat indicators may prevent peer-victimized individuals from adaptive responses to social cues, increasing their vulnerability for depression.

Peer victimization is a risk factor for the development of major depressive disorders, but little is known about the mechanisms. This study examined whether peer victimization alters physiological and affective responses to potentially threatening social stimuli. For this purpose, reactions to socially evaluative stimuli of depressive patients and healthy controls with varying histories of peer victimization were compared. In a social conditioning task, we studied heart rate responses to unconditioned socially negative and neutral evaluative video statements, followed by the heart rate reactions to conditioned stimuli, i.e. still images of the faces of the same actors. Diagnosis of depression and peer victimization were both associated with a more pronounced heart rate deceleration in response to unconditioned stimuli, irrespective of valence. The effect of peer victimization was stronger in depressive patients than in healthy controls. However, heart rate responses to the CSs were not related to depression or peer victimization. The results indicate a hypervigilant processing of social stimuli in depressive patients reporting histories of peer victimization. This distinct processing may be associated with inappropriate behavioral and emotional responses to social challenges, putting individuals at risk for depressive symptoms.

In the general population, prevalence rates of cyberbullying victimization have continuously increased over the past decades. However, the extent to which these increasing numbers affect clinical populations seeking treatment in outpatient services remains an open question. The present study sought to examine whether the increase of cyberbullying victimization is also reflected by increased reports of cyberbullying victimization in a clinical outpatient population. In addition, we assessed the incremental contribution of experiences of cyberbullying in the prediction of psychological symptoms when controlling for histories of childhood maltreatment and offline peer victimization. For this purpose, we analyzed routine data from N = 827 outpatients who had sought treatment at a University outpatient clinic for psychotherapy between 2012 and 2021 in a cross-sectional study design. Analyses showed that 8.3% of the patients born in the years 1980 to 2002 indicated the experience of cyberbullying victimization in their adolescence. The rate of reported cyberbullying victimization increased from 1 to 3% in patients born in the years 1980 to 1987 to 24% in patients born in the year 2000. A logistic regression revealed that patients born in the years 1995-2002 were up to nineteen times as likely to report cyberbullying victimization as patients born in the years 1980-1982. In addition, hierarchical multiple regression analyses indicated that cyberbullying victimization significantly accounted for an incremental proportion of variance (1%) in the prediction of psychological symptom distress after controlling for child maltreatment and offline peer victimization. In conclusion, this retrospective survey indicates an increase of the clinical relevance of cyberbullying victimization both in frequency of and potential contribution to etiology. Raising attention to cyberbullying in clinical care and research seems to be justified and warranted.

Misophonia is characterized by a preoccupation with and strong emotional and behavioral reactions to certain triggers, mostly sounds related to eating and breathing. We applied functional impairment due to misophonic symptoms as a central criterion to investigate differences between clinical misophonia and normative decreased sound tolerance in a large non-random sample of n = 1,881 individuals from an online survey. We assessed the frequency of self-reported misophonia symptoms across various symptom measures, compared severity, triggers and emotional reactions, general psychopathology, interpersonal emotion regulation, and quality of life between both groups with and without functional impairing misophonia. Individuals with functional impairment due to misophonia (n = 839) revealed significantly higher general psychopathology symptoms, lower interpersonal emotion regulation skills, and lower quality of life than individuals without impairment (n = 1,042). Anxious/distressed and annoyed reactions to triggers were experienced more frequently compared to emotional reactions of disgust and sadness or depression in both groups. Overall, the group differences were primarily quantitative in nature. We discuss practical implications regarding classification and treatment and provide cutoffs for each symptom measure derived from group assignment for functional impairment.
RESUMEN
Introduction: Misophonia refers to a phenomenon in which affected individuals have a selective intolerance to sounds of mostly oral or nasal origin. This intolerance is typically associated with strong emotional reactions such as anger, irritation, and disgust. The aim of this study was to conduct the first large epidemiological survey to determine the prevalence of misophonia symptoms in the adult population in Germany. Methods: We conducted a large-scale representative population survey between December 2020 and March 2021. For this purpose, a sample of 2,519 people were visited in their households and assessed with the Misophonia Questionnaire (MQ) and the Amsterdam Misophonia Questionnaire (AMISOS-R) to document misophonic symptoms. The primary estimate of clinical misophonia symptoms prevalence was based on the MQ Severity Scale and a secondary estimate was based on the AMISOS-R. The survey further included self-ratings to measure perfectionism, not-just-right experience (NJRE), autonomous sensory meridian response (ASMR) and general health as well as demographic data. Results: Five percent of the sample scored equal or above the MQ Severity Scale threshold for clinical misophonia symptoms (5.9% based on AMISOS-R). Individuals with clinical misophonia symptoms had a higher rate of perfectionism, a higher occurrence of NJRE, higher susceptibility to ASMR, and a worse general health status than those scoring below the cut-off-score. All those factors also independently predicted the severity of misophonia symptoms in a multiple regression model. Conclusion: Misophonia is a frequent condition and should further be examined as an independent diagnostic entity.
RESUMEN
Childhood maltreatment is a common phenomenon in various psychiatric disorders. Accordingly, patients with disorders from the schizophrenia spectrum (SSD) appear to have high prevalence rates of childhood maltreatment. However, the interpretation and comparability of prevalence rates is impeded by methodological weaknesses and differences such as measures and thresholds used in previous studies. Therefore, we aimed to provide and compare systematically captured data on prevalence rates of all common types of childhood maltreatment in patients with SSD using a standardized and well-established questionnaire and the most frequently used thresholds. The sample consisted of 48 patients with a primary diagnosis of SSD. 58.3-77.1% of the sample experienced at least one type of childhood maltreatment. Prevalence rates for physical abuse, physical neglect, and emotional abuse were dependent on the thresholds used, while equal rates were found for emotional neglect and sexual abuse. Physical neglect (46-67%), and emotional abuse (44-48%) were most commonly reported, followed by emotional neglect (38%), physical abuse (25-38%), and sexual abuse (25%). Additionally, high levels of peer victimization were reported by SSD patients. It appears that childhood maltreatment is a common phenomenon in SSD, even though methodological details, especially cut-off scores, have a substantial impact on the prevalence rates that are determined. Therefore, the methodology of studies should be closely examined when drawing conclusions from presented prevalence rates.
RESUMEN
Depression is associated with abnormalities in patterns of information processing, particularly in the context of processing of interpersonal information. The present study was designed to investigate the differences in depressive individuals in cortical processing of facial stimuli when neutral faces were presented in a context that involved information about emotional valence as well as self-reference. In 21 depressive patients and 20 healthy controls, event-related potentials (ERPs) were recorded during the presentation of neutral facial expressions, which were accompanied by affective context information that was either self- or other-related. Across conditions, depressive patients showed larger mean P100 amplitudes than healthy controls. Furthermore, mean late positive potential (LPP) amplitudes of depressive patients were larger in response to faces in self-related than in other-related context. In addition, irrespective of self-reference, mean LPP responses of depressive patients to faces presented after socially threatening sentences were larger compared with faces presented after neutral sentences. Results regarding self-reference supported results of previous studies indicating larger mean amplitudes in self-related conditions. Findings suggest a general heightened initial responsiveness to emotional cues and a sustained emotion processing of socially threatening information in depressive patients.

Posttraumatic stress disorder (PTSD) is characterized by overgeneralized emotional reactivity following a trauma. Similarities between current, safe contexts and past, threatening events trigger recurrent, distressing responses and can contribute to a host of symptoms, including reexperiencing and hypervigilance. Mnemonic discrimination, a component process of episodic memory, could promote overgeneralization when impaired. Mnemonic discrimination reflects the integration of old and new experiences and one's ability to differentiate them despite their similarities. To date, little research has been conducted in clinical populations and none with individuals with PTSD. In this study, we examined mnemonic discrimination performance among treatment-seeking adults with and without PTSD and healthy comparison participants (n = 190). There were significant group differences in mnemonic discrimination performance, but not in general recognition memory. Individuals without psychopathology outperformed individuals with PTSD and treatment-seeking individuals without PTSD. However, there were no differences in mnemonic discrimination performance among individuals with PTSD and any other diagnoses. Finally, clinical groups with or without trauma exposure also did not differ in mnemonic discrimination performance. Results held when we adjusted for general recognition memory. Findings suggest that poor mnemonic discrimination is transdiagnostically associated with emotional disorders. Future work is merited to explore this as a measurable and potentially malleable, though non-specific, risk factor.

BACKGROUND: Childhood adversities, especially emotional abuse, emotional neglect, and peer victimization are considered to be crucial risk factors for social anxiety disorder (SAD). We investigated whether particular forms of retrospectively recalled childhood adversities are specifically associated with SAD in adulthood or whether we find similar links in other anxiety or depressive disorders. METHODS: Prevalences of adversities assessed with the Childhood Trauma Questionnaire (CTQ) and a questionnaire of stressful social experiences (FBS) were determined in N = 1091 outpatients. Adversity severities among patients with SAD only (n = 25), specific phobia only (n = 18), and generalized anxiety disorder only (n = 19) were compared. Differences between patients with anxiety disorders only (n = 62) and depressive disorders only (n = 239) as well as between SAD with comorbid depressive disorders (n = 143) and SAD only were tested. RESULTS: None of the adversity types were found to be specifically associated with SAD and severities did not differ among anxiety disorders but patients with depressive disorders reported more severe emotional abuse, physical abuse, and sexual abuse than patients with anxiety disorders. SAD patients with a comorbid depressive disorder also reported more severe adversities across all types compared to SAD only. CONCLUSION: Findings indicate that particular forms of recalled childhood adversities are not specifically associated with SAD in adulthood. Previously established links with SAD may be better explained by comorbid depressive symptoms.

BACKGROUND AND OBJECTIVES: The transdiagnostic view of repetitive negative thinking (RNT) claims that different forms of RNT are characterized by identical processes that are applied to disorder-specific content. The purpose of the study was to test whether the processes of RNT differ across major depression disorder (MDD), generalized anxiety disorder (GAD), and obsessive-compulsive disorder (OCD). METHODS: Forty-two individuals diagnosed with MDD, 35 individuals with GAD, 41 individuals with OCD, and 35 community controls were asked to think of a typical RNT episode and to rate its processes (core processes; use of mental capacity, unproductivity, abstractness, verbal quality, duration). Ratings were compared across groups using planned contrasts and analysis of variance. RESULTS: All individuals with a clinical diagnosis rated the key processes of RNT and avoidance function of RNT as higher than healthy controls. There were no differences between individuals diagnosed with MDD, GAD or OCD on key processes and avoidance function of RNT. LIMITATIONS: Results are based on retrospective self-reports, which might restrict validity of the measurements. CONCLUSIONS: Data support the transdiagnostic hypothesis of RNT. Transdiagnostic prevention and intervention techniques seem highly recommendable given these findings.

BACKGROUND AND OBJECTIVES: Cognitive behavioral models of social anxiety disorder (SAD) in adults suggest several mechanisms that maintain social anxiety. So far, little is known about the role of these processes in childhood social anxiety. METHODS: In this study, 21 children with SAD, 21 children with high social anxiety and 21 non-anxious controls (age between 8 and 13 years) were asked about their use of safety behavior in anxiety producing situations. Furthermore, children were asked to indicate their levels of anxiety, self-focused attention and frequency of positive and negative cognitions while engaging in a performance task in front of two adults. RESULTS: As expected, a significant group effect was found for all dependent variables, with children suffering from SAD reporting the most frequent use of safety behavior and highest levels of anxiety, self-focused attention and negative cognitions during the task, followed by socially anxious children and controls. Unexpectedly, only self-focused attention mediated the relationship between general social anxiety and state anxiety in response to the task. LIMITATIONS: We assessed only the general use of safety behavior in social threatening situations and not with respect to the performance task. CONCLUSIONS: The results provide important preliminary evidence for differences between clinical and non-clinical groups in childhood anxiety in maintaining variables as proposed from cognitive models in adults. In particular, self-focused attention seems to be relevant. Targeting the change of inappropriate attentional focus could be promising for treatment improvement in childhood social anxiety.

The present study examined predictors of treatment outcome among children and adolescents with social anxiety disorder (SAD). Seventy-five participants (8-13 years) participated in a 12-session cognitive behavioral group treatment (CBT). Potential predictors were the pre-treatment severity of anxious symptoms assessed from both the child's and parent's perspective as well as depressive symptoms (child report only) and general emotional distress in parent (parent self-report). Furthermore, the relationship between treatment outcome and child's self-reported pre-post changes in self-consciousness and maladaptive anxiety regulation was investigated. Pre-treatment level of social anxiety reported by the child was a significant predictor for outcome, i.e. children with higher levels of social anxiety at pretreatment reported a greater reduction in social anxiety at post-treatment. Reduction in self-consciousness and maladaptive anxiety regulation both predicted reduction in social anxiety, although not independently. The results suggest that tailoring intervention to include strategies for emotion regulation of anxiety may improve treatment outcome.

Scales of rape myth acceptance (RMA) often yield low means and skewed distributions. This is proposed to be because of a change in rape-related beliefs toward more subtle content. Incorporating insights from racism and sexism research, a 30-item self-report scale measuring the acceptance of modern myths about sexual aggression (AMMSA) is presented. Across four studies (total N=1,279), the reliability and validity of parallel German and English versions of the AMMSA scale were examined. The results show that both language versions are highly reliable; compared with a traditional RMA scale, means of AMMSA scores are higher and their distributions more closely approximate normality. Cross-sectional and longitudinal analyses provide evidence for the AMMSA scale's concurrent and predictive construct validity.
