Theory of Mind and physical bullying in preschool children: the role of peer rejection and gender differences.

BACKGROUND: Preschool represents the budding and initial stage of bullying behavior, where perpetration of physical bullying predominates as the primary form of bullying. An in-depth understanding of the factors linked to preschool physical bullying behavior is crucial for enabling early prevention and intervention strategies. OBJECTIVE: The purpose of this study was to examine the relationship between Theory of Mind and physical bullying behavior in 4-6 years old children in kindergarten and the mediating role of peer rejection and gender in this relationship. METHODS: Data on perpetration of physical bullying and peer rejection were obtained from 310 preschool children (age range = 52-79 months, M = 66.85, SD = 7.04) by the peer nomination method, and their Theory of Mind was measured by the Theory of Mind Development Scale. RESULTS: The results showed that Theory of Mind negatively predicted perpetration of physical bullying in preschool children and that Theory of Mind was related to perpetration of physical bullying in preschool children only through peer rejection. Boys were also found to have a stronger association between peer rejection and perpetration of physical bullying in preschool children than girls. CONCLUSION: Peer rejection may play a mediating role between Theory of Mind and perpetration of physical bullying in preschool children. In addition, the relationship between peer rejection and perpetration of physical bullying appears to be stronger for boys than for girls. This contributes to our understanding of the relationship between Theory of Mind and perpetration of physical bullying in preschool children and has implications for how bullying prevention and intervention can be tailored to the gender of young children.

Theory of Mind in Huntington's Disease: A Systematic Review of 20 Years of Research.

Background: People with Huntington's disease (HD) exhibit neurocognitive alterations throughout the disease, including deficits in social cognitive processes such as Theory of Mind (ToM). Objective: The aim is to identify methodologies and ToM instruments employed in HD, alongside relevant findings, within the scientific literature of the past two decades. Methods: We conducted a comprehensive search for relevant papers in the SCOPUS, PubMed, APA-PsyArticles, Web of Science, Redalyc, and SciELO databases. In the selection process, we specifically focused on studies that included individuals with a confirmed genetic status of HD and investigated ToM functioning in patients with and without motor symptoms. The systematic review followed the PRISMA protocol. Results: A total of 27 papers were selected for this systematic review, covering the period from 2003 to 2023. The findings consistently indicate that ToM is globally affected in patients with manifest motor symptoms. In individuals without motor symptoms, impairments are focused on the affective dimensions of ToM. Conclusions: Based on our analysis, affective ToM could be considered a potential biomarker for HD. Therefore, it is recommended that ToM assessment be included as part of neuropsychological evaluation protocols in clinical settings. Suchinclusion could aid in the identification of early stages of the disease and provide new opportunities for treatment, particularly with emerging drugs like antisense oligomers.

Perspectiva holística en salud: la contribución de la Homeopatía / Holistic Perspective in Health: The Contribution of Homeopathy

En el panorama de la salud, el cuerpo humano, en su estado natural, se revela como una intrincada unidad que opera en armonía para mantener el equilibrio dinámico. Sin embargo, esta homeostasis puede verse afectada, dando lugar a la dualidad y a trastornos que comprometen la estabilidad vital. Este artículo propone una reflexión sobre la perspectiva homeopática, destacando su enfoque único en comparación con la medicina convencional. Diferenciándose al tratar al individuo como un todo integrado, la Homeopatía reconoce la transitoriedad de la dualidad representada por las enfermedades y enfatiza la importancia de la armonía entre el cuerpo y la mente en la búsqueda de la homeostasis. Inspirada en las ideas de Hahnemann, la Homeopatía se destaca por su visión holística, rechazando el dualismo estricto y proponiendo intervenciones que van más allá de la supresión de los síntomas. Anclada en la ley de los similares, busca sustancias que reproduzcan los síntomas del paciente en un estado saludable, buscando una cura profunda y la restauración de la unidad dinámica del organismo. A pesar de los desafíos, como la resistencia y la falta de métodos de investigación universalmente aceptados, la Homeopatía persiste a nivel mundial, sugiriendo un valor único. Este artículo promueve una reflexión sobre el enfoque homeopático, enfatizando su contribución a la comprensión de la salud y su papel en el panorama terapéutico.

n the landscape of health, the human body, in its natural state, reveals itself as an intricate unity, operating harmoniously to maintain dynamic balance. However, this homeostasis can be disrupted, leading to duality and disturbances that compromise vital stability. This article reflects on the homeopathic perspective, highlighting its unique approach compared to conventional medicine. Distinguishing itself by treating the individual as an integrated whole, homeopathy recognizes the transience of duality represented by diseases and emphasizes the importance of harmony between body and mind in the pursuit of homeostasis.Inspired by Hahnemann's ideas, homeopathy stands out for its holistic view, rejecting strict dualism and proposing interventions that go beyond symptom suppression. Anchored in the Law of Similars, it seeks substances that would reproduce the patient's symptoms in a healthy state, aiming for a profound cure and the restoration of the dynamic unity of the organism. Despite challenges, such as resistance and a lack of universally accepted research methods, homeopathy persists globally, suggesting unique value. This article encourages reflection on the homeopathic approach, emphasizing

Cross-cultural adaptation of the Mind-Wandering Questionnaire (MWQ) for Brazilian Portuguese and evidence of its validity

Objective: To adapt the Mind-Wandering Questionnaire (MWQ) for the Brazilian context and present evidence of validity based on its internal structure. Methods: A total of 2,682 Brazilian adults from different regions of the country took part in this study. Confirmatory factor analyses and multigroup confirmatory factor analyses (MGCFA) were performed to assess the factor structure of the MWQ. McDonald's omega (ω) was generated to provide reliability indexes. Results: The analyses demonstrated an adequate factor structure for the MWQ adapted to the Brazilian context, corroborating the original article's single-factor model and other adaptation studies. Furthermore, the results demonstrated the instrument's reliability in a Brazilian population (ω = 0.88). Conclusion: The MWQ is thus an adequate, reliable, and quickly administered instrument for those whose aim is to measure deliberate and spontaneous MW in Brazil.

Affective theory of mind in people with mild and moderate Alzheimer's disease.

OBJECTIVE: This study compared the affective theory of mind (ToM) of people with mild and moderate Alzheimer's disease (AD) and healthy older adults and also investigated the relationship between affective ToM and cognitive and clinical functioning in AD people. METHODS: This cross-sectional study included 156 older adults with AD and 40 healthy older adults. We used an experimental task involving reasoning processes in different contextual situations. RESULTS: The affective ToM was impaired in AD groups compared with healthy group, with moderate AD group showing lower performance than mild AD group. The affective ToM task of mild AD group was significantly correlated with the Mini-Mental State Examination (MMSE) and education years. Linear regression showed only education years as a predictor of ToM task performance. The neuropsychiatric symptoms and functionality were not correlated with the affective ToM. CONCLUSIONS: Our findings demonstrated that people with mild and moderate AD presented impairments in affective ToM that can be explained by the difficulties to infer emotion from reasoning processes. In addition, the education years variable proved to be an affective ToM performance's predictor for the mild AD group, but not for the moderate AD group, indicating that ToM abilities are affected differently in different stages of AD. Neuropsychiatric symptoms and functionality seem to have no influence on affective ToM impairments in people with AD.

The effects of reading and watching fiction on the development of social cognition: a systematic review.

Social cognition is an umbrella term used to address the set of neurocognitive processes involved in effective social interaction, such as Theory of Mind and empathy, and is important for understanding of others' intentions and actions and decision making. Narratives can serve as tools for learning social norms and understanding other people, as they involve mental simulations of social interactions. This review aimed to gather the results of current studies on the effects of reading and watching fiction movies on the development of social cognition. We included 16 publications, all of which were empirical studies. The results showed that, depending on individual factors, as well as on the specifics of the intervention, both reading and watching movies seem to influence the processes of development of social cognition, especially if associated with concomitant or subsequent activities, such as discussions. More research is needed to understand the specific details of this relationship.

Cognição Social é um termo usado para se referir a uma coleção de processos neurocognitivos, como Teoria da Mente e Empatia, envolvidos em interações sociais, e é fundamental para a compreensão das ações e intenções de outros indivíduos e para a tomada de decisões. Narrativas podem servir como ferramentas para o aprendizado de normas sociais e para a compreensão de outras pessoas, pois envolvem a simulação mental de interações sociais. Esta revisão teve como objetivo reunir os resultados de estudos atuais sobre os efeitos da leitura e dos filmes de ficção no desenvolvimento da Cognição Social. Foram incluídas 16 publicações, sendo todas estudos empíricos. Os resultados demonstraram que, dependendo de fatores individuais e de aspectos específicos das intervenções, a leitura e os filmes parecem influenciar processos de desenvolvimento da Cognição Social, especialmente se forem associados a atividades como discussões. Mais pesquisas são necessárias para esclarecer os detalhes dessa relação.

Towards a comprehensive approach to mentalization-based treatment for children with autism: integrating attachment, neurosciences, and mentalizing.

Autism spectrum disorder (ASD) is diagnosed based on socio-communicative difficulties, which are believed to result from deficits in mentalizing, mainly evidenced by alterations in recognizing and responding to the mental states of others. In recent years, efforts have been made to develop mentalization-based treatment (MBT) models for this population. These models focus on enhancing individuals' ability to understand and reflect on their own mental states, as well as those of others. However, MBT approaches for people with ASD are limited by their existing theoretical background, which lacks a strong foundation grounded in neuroscience-based evidence properly integrated with attachment, and mentalizing. These are crucial aspects for understanding psychological processes in autism, and as such, they play a pivotal role in shaping the development of tailored and effective therapeutic strategies for this specific population. In this paper we review evidence related to the neurobiological, interpersonal, and psychological dimensions of autism and their implications for mentalizing processes. We also review previous mentalization-based frameworks on the psychosis continuum to provide a comprehensive understanding of attachment, neurobiology, and mentalization domains in therapeutic approaches for autism. After presenting a synthesis of the literature, we offer a set of clinical strategies for the work with children with autism. Finally, we provide recommendations to advance the field towards more robust models that can serve as a basis for evidence-based therapeutic strategies.

Hearts and Minds: Emotion Recognition and Mentalizing in Parkinson's Disease and Progressive Supranuclear Palsy.

OBJECTIVE: There are scarce data comparing Parkinson's disease (PD) and Progressive Supranuclear Palsy (PSP) in social cognition (SC). We aimed to compare patients with PSP and PD in SC. METHODS: We included three groups: PD (n = 18), PSP (n = 20) and controls (n = 23). Participants underwent neuropsychological exams, including the mini-version of the Social and Emotional Assessment, which is composed of the facial emotion recognition test (FERT) and the modified faux-pas (mFP) test, which assesses Theory of Mind (ToM). RESULTS: Patients with PD scored lower than controls in the FERT, but not in the mFP test. Patients with PSP performed worse than controls in both the mFP and FERT. PD and PSP groups did not differ in the FERT, but PSP performed worse than PD in the mFP test. The mFP test distinguished PSP from PD with 89% accuracy. CONCLUSION: The assessment of ToM may contribute to the differentiation between PD and PSP.

An Integrative Hypothesis of Brain Evolution.

The purpose of this article is to reconcile the hypotheses that: (1) brain evolution occurred due to a change in diet, and (2) it occurred due to pressures related to understanding more and more about the underlying causes, such as understanding increasingly complex manipulative and cooperative intentions on the part of the other, as well as understanding reality itself (and how to interact with it beyond group issues). I argue that the ingestion of fat, a highly energy-efficient food, would have unlocked the evolutionary process that culminated in the emergence of the practice of reasoning about underlying causes; and that the consolidation of such a practice resulted in a continuous pressure to increase cognition about "whys"; so that many explanations ended up imposing the need for additional ones, and with that came a high level of awareness and the need for the brain to evolve not only in terms of providing a higher level of cognition but also in size.

Teoria da mente e empatia em adultos típicos: uma revisão de escopo / Theory of mind and empathy in typical adults: a scoping review / Teoría de la mente y empatía en adultos típicos: una revisión panorámica

Teoria da mente e empatia são habilidades sociocognitivas implicadas na compreensão do mundo social e elaboração de respostas em contextos sociais. Entretanto, é preciso ainda avançar na precisão como as pesquisas apresentam esses constructos e as relações entre eles. O objetivo deste estudo foi realizar uma revisão de escopo a respeito das relações conceituais apontadas entre teoria da mente e empatia em pesquisas que investigam diferenças socioindividuais em adultos típicos, bem como organizar essas produções em função de categorias temáticas. Foram analisados 62 artigos, sendo observados cinco diferentes modelos de articulações conceituais entre teoria da mente e empatia e três núcleos de produção temática, ligados ao comportamento social, às variações fisiológicas na vida cotidiana, e, às variações cognitivas, afetivas e sociais. Discutem-se também avanços e limitações nessa área, apontando-se tanto para uma profícua produção como para a necessidade de se avançar na construção de parâmetros mais precisos nessa área. (AU)

Theory of mind and empathy constitute sociocognitive skills central to understanding the social world and formulating responses within social contexts. However, studies continue to face the challenge of clarifying their boundaries and unraveling the presumed connections between them. This study aimed to conduct a scoping review of the conceptual interplay between theory of mind and empathy in research exploring socio-individual differences in typical adults, while also organizing these findings according to thematic categories. A total of 62 articles were analyzed, revealing five different models of relations between theory of mind and empathy, as well as three thematic production nuclei linked to social behavior, physiological variations in daily life, and cognitive, affective, and social variations. The study also discusses advancements and limitations in this field, pointing out both a fruitful production and the need to advance in the construction of more precise parameters in this area. (AU)

People can use the placement of objects to infer communicative goals.

Beyond words and gestures, people have a remarkable capacity to communicate indirectly through everyday objects: A hat on a chair can mean it is occupied, rope hanging across an entrance can mean we should not cross, and objects placed in a closed box can imply they are not ours to take. How do people generate and interpret the communicative meaning of objects? We hypothesized that this capacity is supported by social goal inference, where observers recover what social goal explains an object being placed in a particular location. To test this idea, we study a category of common ad-hoc communicative objects where a small cost is used to signal avoidance. Using computational modeling, we first show that goal inference from indirect physical evidence can give rise to the ability to use object placement to communicate. We then show that people from the U.S. and the Tsimane'-a farming-foraging group native to the Bolivian Amazon-can infer the communicative meaning of object placement in the absence of a pre-existing convention, and that people's inferences are quantitatively predicted by our model. Finally, we show evidence that people can store and retrieve this meaning for use in subsequent encounters, revealing a potential mechanism for how ad-hoc communicative objects become quickly conventionalized. Our model helps shed light on how humans use their ability to interpret other people's behavior to embed social meaning into the physical world.

Performance in emotion recognition and theory of mind tasks in social anxiety and generalized anxiety disorders: a systematic review and meta-analysis.

Social cognition impairments may be associated with poor functional outcomes, symptoms, and disability in social anxiety disorder (SAD) and generalized anxiety disorder (GAD). This meta-analysis aims to determine if emotion recognition and theory of mind (ToM) are impaired in SAD or GAD compared to healthy controls. A systematic review was conducted in electronic databases (PubMed, PsycNet, and Web of Science) to retrieve studies assessing emotion recognition and/or ToM in patients with SAD or GAD, compared to healthy controls, up to March 2022. Meta-analyses using random-effects models were conducted. We identified 21 eligible studies: 13 reported emotion recognition and 10 ToM outcomes, with 585 SAD patients, 178 GAD patients, and 753 controls. Compared to controls, patients with SAD exhibited impairments in emotion recognition (SMD = -0.32, CI = -0.47 - -0.16, z = -3.97, p < 0.0001) and ToM (SMD = -0.44, CI = -0.83 -0.04, z = -2.18, p < 0.01). Results for GAD were inconclusive due to the limited number of studies meeting the inclusion criteria (two for each domain). Relevant demographic and clinical variables (age, sex, education level, and anxiety scores) were not significantly correlated with emotion recognition or ToM impairments in SAD and GAD. Further studies employing ecological measures with larger and homogenous samples are needed to better delineate the factors influencing social cognition outcomes in both SAD and GAD.

Relación entre modelos operantes internos y nivel educacional materno, con la teoría de la mente en niños chilenos de 3 y 4 años: rol mediador del lenguaje mentalizante materno / Relationship between Internal Working Models and Maternal Educational Level, with the Theory of Mind of Chilean Children Aged 3 and 4: Mediating Role of Maternal Mentalizing Language

Resumen La teoría de la mente (ToM) es la capacidad de reconocer los propios estados mentales y predecir los de otros, habilidad fundamental en el desarrollo socioemocional/cognitivo en preescolares. El presente estudio buscó describir la ToM de niños chilenos de 3 y 4 años, analizar las diferencias en su desarrollo según la edad y el rol mediador del lenguaje mentalizante (LM) materno, considerando el sexo de los niños, los modelos operantes internos (MOI) y el nivel educacional materno. La muestra fueron 110 niños con sus madres. Se aplicó un cuestionario sociodemográfico, pruebas para evaluar la ToM, el LM y los MOI de las madres. Un 50.9% de los niños se ubicó en el quintil 1 de la ToM y ninguno logró llegar al quinto. Las habilidades de la ToM con un mayor nivel de logro diferenciaron entre pretender y realidad (60.0%) y la de diferenciar la perspectiva visual propia y de otro (50.9%). Un 59.1 % de los niños no logró inferir deseos a través de la mirada, un 83.6% no logró la habilidad de acceso al conocimiento, y un 100% no logró la falsa creencia. Los resultados muestran diferencias significativas entre niños de distintos rangos etarios en el desarrollo de la ToM, sugiriendo una creciente dificultad de adquisición de sus habilidades. Además, un mayor LM de las madres se relacionó con mayor desarrollo de la ToM en los niños, con un rol mediador en la influencia de los MOI y nivel educacional materno sobre la ToM.

Abstract The theory of mind (ToM) is the ability to recognize one's own mental states and infer them in others, fundamental in socio-emotional/cognitive development in preschoolers. This study sought to describe the ToM of 3- and 4-year-old Chilean children, to analyze the differences in their development according to age, and the mediating role of maternal mentalizing language (ML) considering the sex of the children, the internal working models (IWM) and maternal educational level. The sample considered 110 children with their mothers. A sociodemographic questionnaire, tests to evaluate the ToM, the ML and the IWM of the mothers were applied. 50.9% of the children were in quintile 1 of the ToM and none managed to reach the fifth. The ToM skills with a higher level of achievement were differentiating between pretending and reality (60.0%) and differentiating one's own visual perspective and another's (50.9%). 59.1 % of the children did not manage to infer wishes through the gaze, 83.6% did not achieve the ability to access knowledge, and 100% did not achieve the false belief. The results show significant differences between children of different age ranges in the development of ToM, suggesting a growing difficulty in acquiring their skills. In addition, a higher ML in mothers was related to a greater development of ToM in children, with a mediating role in the influence of IWM and maternal educational level on ToM.

Influence of blood phenylalanine level variations on the development of executive functions and social cognition in children with phenylketonuria.

OBJECTIVE: To investigate the performance of 27 children with phenylketonuria (PKU) in tests of Executive Functions (EF) and Social Cognition (SC), and their associations with metabolic control inferred by phenylalanine (Phe) levels. METHODS: The PKU group was dichotomized according to baseline Phe-levels into; "classical PKU"(n = 14), with Phe-levels above 1200 µmol/L (> 20 mg/dL); and "mild PKU" (n = 13) with Phe-between 360 and 1200 µmol/L (6-20 mg/dL). The neuropsychological assessment focused on the EF and SC subtests of the NEPSY-II battery and intellectual performance. Children were compared to age-matched healthy participants. RESULTS: Participants with PKU presented significantly lower Intellectual Quotient (IQ) compared to controls (p = 0.001). Regarding EF analysis adjusted by age and IQ, significant differences between groups were observed only in the executive attention subtests (p = 0.029). The SC set of variables was significantly different between groups (p = 0.003), as in the affective recognition task (p < 0.001). In the PKU group, the relative variation of Phe-achieved 32.1 ± 21.0%. Relative Phe-variation was correlated only with measures of Working Memory (p < 0.001), Verbal Fluency (p = 0.004), Inhibitory Control (p = 0.035) and Theory of Mind (p = 0.003). CONCLUSIONS: Phonological Verbal Fluency, Working Memory, Inhibitory Control, and Theory of Mind were shown to be most vulnerable when there is non-ideal metabolic control. Variations in the level of Phe-may have a selective negative effect on Executive Functions and Social Cognition, but not on intellectual performance.

Social Cognition and Prosocial Behavior in Children with Attention Deficit Hyperactivity Disorder: A Systematic Review.

The purpose of this research is to analyze the empirical evidence on the relationship between social cognition and prosocial behavior in children and adolescents with Attention Deficit Hyperactivity Disorder (ADHD). A systematic review was carried out following the PRISMA guidelines of empirical studies found in PubMed and Scopus databases, including a total of 51 research studies. The results indicate that children and adolescents with ADHD have deficits in social cognition and prosocial behavior. For children with ADHD, their deficits in social cognition highlight their difficulty in the process of theory of mind, emotional self-regulation, emotion recognition and empathy, affecting prosocial behavior, evidencing difficulty in personal relationships, and the creation of emotional bonds with their peers.

A comparative study of well-being, resilience, mindfulness, negative emotions, stress, and burnout among nurses after an online mind-body based intervention during the first COVID-19 pandemic crisis.

Background: To mitigate against the possible adverse effects of stress among nurses due to the COVID-19 outbreak, we designed a 12-week mind-body based online intervention program to promote well-being and prevent stress-related disorders such as burnout. Our study aimed to compare the impact of the intervention on perception of stress, negative emotions, burnout, mindfulness, resilience, and well-being at pretest and 6 months post-intervention and to compare the effect among nurses working at two different hospitals. Methods: We conducted an uncontrolled trial using a convenience sample of nurses working at two hospitals in Mexico: one designated to treat confirmed COVID-19 patients (COVID-hospital) and the other whose patients had a negative COVID-19 test on admission (Non COVID-hospital). The 12 week online intervention consisted of 36 mind-body based micropractices, with subjective well-being as the primary outcome. Secondary outcomes were health perception, resilience, mindfulness, negative emotions, stress, and burnout. Results: A pretest survey was completed by 643 nurses. Of the remaining valid responses, 82% were women, with a mean age of 34.8 (SD = 8.95) years old. For the analysis two groups of nurses were sampled by cluster: a COVID-hospital group of 429 (67%) nurses, and a non-COVID Hospital group of 214 (33%) nurses. The proportion lost to follow-up was 71% at postest (n = 188) and 42% at 6 months follow-up (n = 371). At pretest, non-COVID hospital nurses had lower subjective well-being and higher burnout than their COVID hospital counterparts. At postest, non-COVID hospital nurses displayed more negative emotions than their COVID hospital peers. At 6 months post-intervention, nurses experienced improved mindfulness, reduced negative emotions and stress, but a decrease in subjective well-being and resilience. Nurses working at the non-COVID hospital had significantly higher mean scores for burnout than those working at the COVID hospital. Conclusion: The results of our study suggest that our online mind-body interventions can help to reduce stress and negative emotions, yet the effects on subjective well-being and resilience are uncertain. Further research is needed to gain a better understanding of their potential mechanisms and the associated efforts of such online interventions.

The division of linguistic labour for offloading conceptual understanding.

The division of linguistic labour (DLL), initially theorized by philosophers, has gained the attention of cognitive scientists in the last decade. Contrary to some controversial philosophical accounts of DLL, we propose that it is an extended mind strategy of offloading conceptual understanding onto other people. In this article, we empirically explore this proposal by providing an exploratory experimental paradigm to search for the mechanisms underwriting DLL and how they may work in practice. We developed a between-subjects experiment in which participants had to categorize two pairs of highly confusable dog breeds after receiving categorization training on just one pair of breeds. In the treatment group, participants were grouped in dyads and were allowed to interact with each other by means of the labels of these four dog breeds. In their queries to trained 'experts', novices frequently used labels to refer to breeds that they could not identify themselves. Experts were highly responsive to their paired novices' queries, and the rates of querying for the two members within a dyad were positively correlated. Independent categorization failure and offloading categorization success lead to subsequent increases in querying by novices, indicating adaptive use of offloading. Self-reports of breed knowledge were higher for experts within a dyad compared to isolated experts. This article is part of the theme issue 'Concepts in interaction: social engagement and inner experiences'.

Validation and clinical application of the Metacognitions Questionnaire in a sample of Brazilian generalized anxiety disorder patients: the effects of different treatment interventions.

INTRODUCTION: Metacognitive beliefs about worry may trigger anxiety. However, the effect of generalized anxiety disorder (GAD) treatment on metacognition has not yet been investigated. OBJECTIVES: To validate the Metacognitions Questionnaire (MCQ-30) in a Brazilian GAD sample and verify whether different interventions reduce metacognitive beliefs. METHOD: We recruited 180 GAD individuals and randomized them to Body in Mind Training (BMT), Fluoxetine (FLX), or an active control group (Quality of Life [QoL]) for 8 weeks. The MCQ-30 was assessed for internal consistency, was evaluated with confirmatory and exploratory factor analyses, and was tested for convergent validity with the Penn State Worry Questionnaire (PSWQ). Generalized estimating equations (GEE) were employed to analyze differences after the interventions. RESULTS: The MCQ-30 demonstrated good internal consistency and acceptability; the original five-factor model was supported. There was a positive moderate correlation between MCQ-30 scores and worry. GEE showed a significant group x time interaction (p < 0.001). Both BMT (mean difference [MD] = -6.04, standard error [SE] = -2.39, p = 0.034) and FLX (MD = -5.78, SE = 1.91, p = 0.007) reduced MCQ-30 scores. FLX was superior to QoL, but not BMT, at weeks 5 and 8. There were no differences between BMT and QoL. CONCLUSION: The Brazilian-Portuguese version of MCQ-30 showed good psychometric properties. Furthermore, the positive effect of FLX and BMT on metacognition suggests it may represent a potential therapeutic target.

Lavagem cerebral: ciência, mito e pseudociência do controle psicológico / Lavado de cerebro: ciencia, mito y pseudociencia del control psicológico / Brainwashing: science, myth, and pseudoscience of psychological control

Resumo O interesse pela possibilidade de reconfigurar a mente humana foi recorrente na história da humanidade, sob diferentes formas aliadas principalmente à religião, à guerra e à política. Somente a partir de 1950, entretanto, é que psicólogos, psiquiatras e outros pesquisadores se dedicaram com maior profundidade ao tema, popularizado pelo termo genérico de lavagem cerebral. O objetivo deste artigo é revisar as bases teórico-conceituais e metodológicas desses esforços, assim como sua manifestação atualizada na psicologia social, quando se busca a modificação de atitudes, crenças e comportamentos. São analisados criticamente os usos da lavagem cerebral para gerar mudanças significativas por técnicas de pressões psicológicas e tortura física, os mitos de sua implementação e sua (ir)reversibilidade.

Abstract The interest in the possibility of reconfiguring the human mind has been recurrent in the history of humanity, in different forms, mainly allied to religion, war, and politics. Only after 1950, however, did psychologists, psychiatrists, and other researchers dedicate themselves in greater depth to the topic, popularized by the generic term brainwashing. The aim of this paper is to review the theoretical-conceptual and methodological bases of these efforts, as well as their updated manifestation in social psychology, when one seeks to modify attitudes, beliefs, and behaviors. The uses of brainwashing to generate significant change through techniques of psychological pressure and physical torture, the myths of its implementation, and its (ir)reversibility, are critically analyzed.
