RESUMO
IMPORTANCE AND OBJECTIVES: Childhood adversity is a strong risk factor for the development of various psychopathologies including major depressive disorder (MDD). However, not all depressed patients experience early life trauma. Functional magnetic resonance imaging (fMRI) studies using facial emotion processing tasks have documented altered blood-oxygen-level-dependent (BOLD) responses in specific cortico-limbic networks both in MDD patients and in individuals with a history of childhood maltreatment (CM). Therefore, a history of maltreatment may represent a key modulating factor responsible for the altered processing of socio-affective stimuli. To test this hypothesis, we recruited MDD patients with and without of maltreatment history to study the long-term consequences of childhood trauma and examined the impact of CM on brain activity using a facial emotion recognition fMRI task. METHODS: MDD patients with childhood maltreatment (MDD + CM, n = 21), MDD patients without maltreatment (MDD, n = 19), and healthy controls (n = 21) matched for age, sex and intelligence quotient underwent fMRI while performing a block design facial emotion matching task with images portraying negative emotions (fear, anger and sadness). The history of maltreatment was assessed with the 28-item Childhood Trauma Questionnaire. RESULTS: Both MDD and MDD + CM patients displayed impaired accuracy to recognize sad faces. Analysis of brain activity revealed that MDD + CM patients had significantly reduced negative BOLD signals in their right accumbens, subcallosal cortex, and anterior paracingulate gyrus compared to controls. Furthermore, MDD + CM patients had a significantly increased negative BOLD response in their right precentral and postcentral gyri compared to controls. We found little difference between MDD and MDD + CM patients, except that MDD + CM patients had reduced negative BOLD response in their anterior paracingulate gyrus relative to the MDD group. CONCLUSIONS: Our present data provide evidence that depressed patients with a history of maltreatment are impaired in facial emotion recognition and that they display altered functioning of key reward-related fronto-striatal circuits during a facial emotion matching task.
RESUMO
BACKGROUND: Detection of childhood traumas is important both in clinical practice and in research. There is a pressing need for methods that are relatively simple but comprehensive, non-intrusive, and possess adequate psyc - ho metric properties. In this study we translated one of the most widely used and well-studied measure of childhood abuse and neglect and explored the psychometrical properties of this questionnaire. METHODS: The study was based on data from a clinical (N=171) and a normative (N=358) sample. In total 529 adults participated in the testing process. Beside the trauma questionnaire Parental Bonding Inventory, Impact of Events Scale and Dissociative Experiences Scale were administered. RESULTS: We examined the internal consistency of the translated trauma questionnaire. The Cronbach's a coefficients for the five subscales ranged from 0,639 to 0,934. Participants in the clinical sample reached higher scores on all trauma subscales except sexual abuse, than normative adults [PA: t (398)=-2,771; p=0,006; PN: t (398)=-5,990; p=0,000; EA: t (398)=-3,679; p=0,000; EN: t (398)=-4,759; p=0,000; total score: t (398)=-4,669; p=0,000]. Correlations among the trauma questionnaire total score and the scales of Parental Bonding Inventory indicating some medium effects (with maternal care: r=-0,661; p=0,000; with paternal care: r=-0,483; p=0,000). CONCLUSION: Our preliminary findings suggest that this trauma questionnaire is practical and facilitates the systema - tic evaluation of adverse early life events and maximizes the possibility of detecting childhood abuse and neglect.
