简要总结
The study will investigate how a history of emotional childhood maltreatment (CM) is associated with different aspects of psychological (social behaviour, empathy) and biological (brain function and structure, inflammation) health. In fact, CM is a risk factor for many mental disorders, such as schizophrenia and autism. However, it is unclear how a history of emotional CM affects psychological and biological outcomes in bipolar disorder (BD). Therefore, this study focuses on understanding how a possible history of CM affects BD compared to control participants (CP) with no known psychiatric illness.
The aim of the project is to investigate how a history of emotional CM is associated with social cognition. The investigators will recruit 80 CP and 80 people diagnosed with BD, some of whom will have a history of CM. The investigators will assess psychological well-being (social behaviour, empathy) at two points in time at the Department of Psychiatry, Psychotherapy, Psychosomatics and Medical Psychology at the Medical University of Innsbruck (MUI). Additionally, as they want to understand how emotional CM affects brain function and structure, the investigators will perform magnetic resonance imaging (MRI) of the brain at the Neuroimaging Core Facility (Medical University of Innsbruck). The investigators also want to understand how biological markers in the blood (such as telomere length, inflammation) might be affected, assessed in collaboration with the Department of Psychology (Leopold-Franzens University of Innsbruck). Finally, the investigators will look at a combination of the psychological and biological tests to see if there is a link between emotional CM and health outcomes.
详细描述
Although the contribution of childhood maltreatment (CM) to psychological (e.g. social cognition) and biological (e.g. neural, biomolecular) outcomes has been extensively studied, e.g. in schizophrenia and autism, its contribution to bipolar disorder (BD) and the role of different CM subtypes, multiplicity and timing remains unclear. The aim of the project is to investigate how a history of emotional CM is associated with multidimensional aspects of social cognitive, neural and biomolecular parameters.
The research questions addressed in this project are: i) How is a history of emotional CM associated with social cognition in control participants (CP) with no known psychiatric illness and in individuals diagnosed with BD? ii) How is a history of emotional CM related to biomolecular and neural parameters in CP and individuals diagnosed with BD? iii) How are biomolecular markers, neural parameters, and social cognitive skills related in individuals with a history of emotional CM? The primary aim of this study is to investigate the association of self-reported history of emotional CM with social cognition (i.e. emotion recognition, cognitive and affective empathy) in CP and in individuals diagnosed with BD, both with and without a history of CM. Additional aims are to characterize the association of history of emotional CM with neural (i.e. task-based and resting-state functional magnetic resonance imaging (rs-fMRI), morphometry, white matter) MRI parameters and biomolecular markers (i.e. telomere length, mitochondrial bioenergetics and biogenesis) in peripheral blood mononuclear cells and blood plasma (selected immune-response mediators).
Recruitment, clinical assessments (e.g. Maltreatment and Abuse Chronology of Exposure scale) and blood sampling of 80 CP and 80 individuals diagnosed with BD with and without a history of CM will be performed at two timepoints at the Department of Psychiatry, Psychotherapy, Psychosomatics and Medical Psychology, Medical University of Innsbruck (MUI). Longitudinal MRI acquisitions will be performed at the Neuroimaging Core Facility (MUI). Clinical, MRI and biomolecular analyses will be applied, and correlations of these findings with emotional CM, multiplicity and timing will be evaluated.
The contribution of a history of emotional CM to psychological and biological outcomes in BD is unknown. This study will clarify the association between emotional CM and social cognition in BD and CP. It will study how emotional CM alters brain function and structure in regions related to social cognition. A translational approach combining MR neuroimaging with psychoneuroimmunological methods will assess neural parameters together with biomolecular markers from whole blood in relation to emotional CM and social cognition.

Correlation between a history of emotional childhood maltreatment score (Maltreatment and Abuse Chronology of Exposure; MACE-X) and emotion recognition of adult faces (Reading the Mind in the Eyes Test; RMET)
时间窗: In bipolar disorder, at enrollment (in moderate or severe depressed state) and at improved clinical state (response or remission) at 3-6 months after enrollment. In control participants, at enrollment and at 3-6 months after.
Correlation between a history of emotional childhood maltreatment score (as assessed by a combined score of the Maltreatment and Abuse Chronology of Exposure \[MACE-X\] emotional subscales: parental verbal abuse, parental nonverbal emotional abuse, emotional neglect, peer verbal abuse) and emotion recognition (number of correctly identified emotions) as assessed by the Reading the Mind in the Eyes Test adult version (RMET). RMET use expressions from images of 28 adult faces, 50% male and 50% female. The task consist of two types of trials: emotion recognition and sex judgment. In the emotion recognition trials, participants select among four adjectives the one that best describes what the person in the image is thinking or feeling. This task is sensitive to subtle emotion processing deficits since it involves the recognition of a relatively wide range of complex mental states.

Correlation between a history of emotional childhood maltreatment score (Maltreatment and Abuse Chronology of Exposure scale; MACE-X) and cognitive empathy (Multifaceted Empathy Test; MET-core 2)
时间窗: In bipolar disorder, at enrollment (in moderate or severe depressed state) and at improved clinical state (response or remission) at 3-6 months after enrollment. In control participants, at enrollment and at 3-6 months after.
Correlation between a history of emotional childhood maltreatment score (Maltreatment and Abuse Chronology of Exposure scale; MACE-X) and cognitive empathy (number of correctly identified) as assessed by The Multifaceted Empathy Test (MET-core 2). MET-core 2 is an ecologically valid measure that allows separate assessment of cognitive and affective empathy. It consists of 40 photographs depicting people in emotionally charged situations and is designed to elicit strong emotional reactions. To assess cognitive empathy ("What is the person feeling?"), the mental states of the people in the photographs are selected from four mental state descriptors. To assess affective empathy ("How much are you feeling for the person?"), the level of empathic concern for the depicted individuals is rated on a 4-point Likert scale (from "not at all" to "very strong") for the same series of pictures.
