The Centrality of Humiliation in Complex Posttraumatic Stress Disorder.

Victims of traumatic events that involve repeated interpersonal aggression and low or no chance of escape frequently report intense Self-Conscious Emotions (SCEs), such as Shame, Guilt, and Humiliation. Humiliation is the reaction to a forced loss of status and is hypothesized to have unique contributions to the development and maintenance of Posttraumatic Stress Disorder (PTSD) and Complex Posttraumatic Stress Disorder (CPTSD). However, previous studies did not include humiliation or did not simultaneously probe the relative contribution of each SCE to posttraumatic symptoms.

International Trauma Questionnaire and Posttraumatic Cognitions Inventory-9: validity evidence and measurement invariance of their Brazilian versions.

Background: The International Trauma Questionnaire (ITQ) is used to measure posttraumatic stress disorder (PTSD) and complex posttraumatic stress disorder (CPTSD) symptoms, and the Posttraumatic Cognitions Inventory-9 (PTCI-9) is used to measure posttraumatic cognitions. Both tools have been translated for use in Brazil. However, the psychometric properties of the Brazilian versions were not investigated, and no study has verified the invariance of these tools for many traumatic event types.

Aversiveness of errors and the error-related negativity (ERN): A systematic review on the affective states' manipulations findings.

Error-related negativity (ERN) has been used to investigate neural mechanisms underlying error processing and conflict monitoring. Recent evidence highlights that affective and motivational states modulate the ERN and that aversiveness of errors plays a vital role in error monitoring. Therefore, our primary objective was to systematically evaluate and describe the influence of affect state-related manipulations on the ERN.

Psychiatric outcomes and overall functioning in healthcare students during the first wave of the COVID-19 pandemic: a cross-sectional study.

Introduction: There is evidence that the coronavirus disease 2019 (COVID-19) pandemic impacted students on health care courses, including evidence of associations between anxiety or depression and inadequate coping mechanisms or unhealthy habits. However, little is known about possible predictors of mental health or psychiatric symptoms in Brazilian health care students during this period.

Objective: To evaluate possible factors associated with anxiety and depressive symptoms, used to measure psychiatric outcomes, and quality of life, used as a parameter of overall functionality, in Brazilian students on health care courses during the COVID-19 pandemic.

Effects of Temporal Expectations on the Perception of Motion Gestalts.

Gestalt psychology has traditionally ignored the role of attention in perception, leading to the view that autonomous processes create perceptual configurations that are then attended. More recent research, however, has shown that spatial attention influences a form of Gestalt perception: the coherence of random-dot kinematograms (RDKs). Using ERPs, we investigated whether temporal expectations exert analogous attentional effects on the perception of coherence level in RDKs.

Who is in charge when I have a headache? Brazilian version of the Headache-Specific Locus of Control Scale.

Background: Headache-Specific Locus of Control (LOC) refers to individuals' beliefs about their control over the onset, course and consequences of headaches. LOC beliefs have been associated with depression, coping strategies, headache-related disability and treatment outcomes.

Objective: To test the cross-cultural adaptation and psychometric properties of a Brazilian version of the Headache-Specific Locus of Control Scale (HSLC).

Implicit processing during inattentional blindness: A systematic review and meta-analysis.

The occurrence of implicit processing of visual stimuli during inattentional blindness is still a matter of debate. To assess the evidence available in this debate, we conducted a systematic review of articles that explored whether unexpected visual stimuli presented during inattentional blindness are implicitly processed despite not being reported. Additionally, we employed meta-analysis to combine 59 behavioral experiments and investigate the statistical support for such implicit processing across experiments.

Psychometric properties of the Brazilian Intolerance of Uncertainty Scale - Short Version (IUS-12).

Introduction The Intolerance of Uncertainty Scale - Short Version (IUS-12) is a measure of trait intolerance of uncertainty. Objective The purpose of the present study was to conduct a cross-cultural adaptation of the IUS-12 for use in Brazil and to investigate the scale's psychometric properties. Methods The research was conducted via an online research platform with a sample (n = 704; 80.

S-Ketamine's Effect Changes the Cortical Electrophysiological Activity Related to Semantic Affective Dimension of Pain: A Placebo- Controlled Study in Healthy Male Individuals.

Background: Previous studies using the electroencephalogram (EEG) technique pointed out that ketamine decreases the amplitude of cortical electrophysiological signal during cognitive tasks, although its effects on the perception and emotional-valence judgment of stimuli are still unknown.

Objective: We evaluated the effect of S-ketamine on affective dimension of pain using EEG and behavioral measures. The hypothesis was that S-ketamine would be more effective than placebo, both within and between groups, to attenuate the EEG signal elicited by target and non-target words.

Psychometric properties of the Posttraumatic Growth Inventory in a sample of Brazilian university students.

Objective: To examine psychometric properties of the Brazilian version of the Posttraumatic Growth Inventory (PTGI).

Method: A total of 300 university students were evaluated though instruments that investigated trauma history, depression and posttraumatic symptoms, and personality traits through the Big Five model. Pearson's correlation was used to assess internal consistency, inter-item reliability and construct validity.

Translation and adaptation of the Child Posttraumatic Cognitions Inventory (cPTCI) to Brazilian Portuguese.

Introduction: Experiencing a traumatic event is a risk factor for the development of mental illness, especially posttraumatic stress disorder. A child's appraisals of a traumatic event may play a prominent role in the development or maintenance of the disorder. Therefore, subjective responses should be evaluated to understand the impact of a traumatic event on a child's life.

Alexithymia and its impact on quality of life in a group of Brazilian women with migraine without aura.

Background: Migraine is a type of primary headache widely known for its impact on quality of life of patients. Although the psychological aspects of the disease are receiving increasing attention in current research, some of them, as alexithymia, are still seldom explored. This study aimed to provide evidence on the relationships between markers of depression, anxiety, alexithymia, self-reflection, insight and quality of life in migraine.
