Psychogenic movement disorder is defined as abnormal movements unrelated to a medical cause and presumed related to underlying psychological factors. Although psychological factors are of both clinical and pathophysiological relevance, very few studies to date have systematically assessed their role in psychogenic movement disorder. We sought to assess the role of previous life stress using validated quantitative measures in patients with psychogenic movement disorder compared with age- and sex-matched healthy volunteers as well as a convenience sample of patients with focal hand dystonia. Sixty-four patients with psychogenic movement disorder (72% female; mean age, 45.2 years [standard deviation, 15.2 years]), 38 healthy volunteers (74% female; mean age, 49 years [standard deviation, 13.7 years]), and 39 patients with focal hand dystonia (37% female; mean age, 48.7 years [standard deviation, 11.7 years]) were evaluated using a standardized psychological interview as well as validated quantitative scales to assess trauma and previous stressors, depression, anxiety, and personality traits. Patients with psychogenic movement disorder reported higher rates of childhood trauma, specifically greater emotional abuse and physical neglect, greater fear associated with traumatic events, and a greater number of traumatic episodes compared with healthy volunteers and patients with focal hand dystonia controlled for depressive symptoms and sex (Bonferroni corrected P < .005). There were no differences in categorical psychiatric diagnoses or scores on childhood physical or sexual abuse subscales, personality traits, or the dissociative experience scale. Our findings highlight a biopsychosocial approach toward the pathophysiology of psychogenic movement disorder, although the association with psychological issues is much less prominent than expected compared with the nonepileptic seizure population. A careful psychological assessment is indicated to optimize therapeutic modalities.

The role of rejection sensitivity as a critical diathesis moderating the link between adolescent relational stressors and depressive symptoms was examined using multi-method, multi-reporter data from a diverse community sample of 173 adolescents, followed from age 16 to 18. Relational stressors examined included emotional abuse, maternal behavior undermining adolescents' autonomy and relatedness, and lack of support from close peers. As hypothesized, multiple relational stressors were found to predict the future development of depressive symptoms, but as hypothesized predictions existed primarily for adolescents who were highly rejection sensitive. Results are discussed in terms of a diathesis-stress model of depression and suggest that though relational stressors have previously shown consistent modest links to depressive symptoms, understanding pre-existing intrapsychic vulnerabilities of the adolescent may be critical to identifying the processes by which such stressors lead to depressive symptoms.

While the overwhelming majority of research on the consequences of childhood maltreatment reports differential outcomes of specific maltreatment subtypes (e.g., physical abuse vs. emotional abuse) as though they are independent, maltreatment experiences often occur in combination. The present study evaluated multiple maltreatment experiences in a sample of 2,637 undergraduate students who reported on childhood maltreatment and current adjustment. The authors used latent class analysis to examine predominant patterns of multiple maltreatment experiences and investigated indices of psychosocial adjustment associated with those patterns. Results suggested that specific constellations of multiple maltreatment have qualitatively different associations with adjustment. Emotional abuse, alone or in combination with other maltreatment types, was especially salient for psychopathology (e.g., anxiety, depression), while a combination of physical and emotional abuse was most strongly associated with conduct-related problems (e.g., substance use, risky sexual behavior). These findings have both practical and empirical significance for understanding and classifying experiences of maltreatment.

In the context of chronic childhood emotional maltreatment (CEM; emotional abuse and/or neglect), adequately responding to facial expressions is an important skill. Over time, however, this adaptive response may lead to a persistent vigilance for emotional facial expressions. The amygdala and the medial prefrontal cortex (mPFC) are key regions in face processing. However, the neurobiological correlates of face processing in adults reporting CEM are yet unknown. We examined amygdala and mPFC reactivity to emotional faces (Angry, Fearful, Sad, Happy, Neutral) vs scrambled faces in healthy controls and unmedicated patients with depression and/or anxiety disorders reporting CEM before the age of 16 years (n = 60), and controls and patients who report no childhood abuse (n = 75). We found that CEM was associated with enhanced bilateral amygdala reactivity to emotional faces in general, and independent of psychiatric status. Furthermore, we found no support for differential mPFC functioning, suggesting that amygdala hyper-responsivity to emotional facial perception in adults reporting CEM may be independent from top-down influences of the mPFC. These findings may be key in understanding the increased emotional sensitivity and interpersonal difficulties, that have been reported in individuals with a history of CEM.

This study aims to determine the relationship between psychological, physical, and sexual abuse, and mental health symptoms. Female college students (N = 499) completed anonymous online surveys to report experiences of abuse, as well as symptoms of depression, posttraumatic stress disorder (PTSD), and physical injuries. Five groups of participants were found: no abuse; psychological abuse; physical abuse; psychological and physical abuse; and psychological, physical, and sexual abuse. The multiple abuse groups showed the highest rate of mental health symptoms. In addition, increased frequency of abuse was related to more mental health symptoms and more physical injuries.

Many community-residing older adults in the United States report past year mistreatment; however, little is known about mental health correlates of abuse. This study investigated whether a recent history of emotional, physical, or sexual abuse is associated with self-reported emotional symptoms (e.g., anxiety, depression) among a representative sample of older adults. Results demonstrated that each abuse type increased likelihood of reporting emotional symptoms; when other known correlates were controlled, only emotional abuse remained a significant predictor. Additional study of mistreatment-related correlates of depression and anxiety is needed, with a focus on the often overlooked category of emotional mistreatment.

Juvenile offenders are at risk for involvement in both fighting behavior and peer victimization. Understanding the potential causal mechanisms leading to these outcomes is important to address the needs of this population. The present study tested four mediator models of violent perpetration and peer victimization in a sample of 112 incarcerated youth (68 males and 44 females). In the models, the relationship between child physical and emotional abuse and fighting and victimization was expected to be mediated by impulsiveness, depression, and drug use. Multiple mediator models were tested according to Preacher and Hayes (2008). Depression fully mediated the relation between child emotional abuse and victimization and partially mediated the relation between child physical abuse and victimization. Drug use fully mediated the relation between child emotional abuse and fighting. These results suggest that treatment of depressive symptoms and drug use among juvenile offenders with a history of child physical or emotional abuse may limit violent perpetration and peer victimization in this population.

Child abuse has proved to be one of the most important social challenges. The present study attempts (a) to determine the prevalence of child abuse in an urban area in Iran and (b) to differentiate abused from non-abused adolescent boys using parental and child characteristics. A survey was conducted to determine the prevalence of different types of child abuse. The prevalence sample comprised 2,100 students selected through a multistage random sampling procedure. Data were collected using the Childhood Trauma Questionnaire (CTQ), Beck Depression Inventory, II (BDI-II), State Trait Anxiety Inventory (STAI), modified Hazan & Shaver Attachment Style Questionnaire (ASQ) and Symptom Check List 90 (SCL-90-R). Descriptive statistics and discriminant function analysis were used to analyze the data. The results showed that 14.85% of the subjects were exposed to child abuse, with emotional abuse being most prevalent (52.09%). Also, it appeared that variables such as parental depression and anxiety and children's attachment styles, anxiety, and aggression can help discriminate abused boys from their non-abused counterparts.

Overgeneral autobiographical memory (OGM) is associated with depression and may confer risk for the development of depressed mood, but few longitudinal studies have evaluated OGM as a predictor of depressive symptoms in early adolescence, particularly in the context of environmental stressors. We investigated whether OGM and emotional maltreatment would interact to predict prospective increases in depressive symptoms in early adolescents and whether these effects differed by race. Among 174 seventh-graders, OGM and familial emotional abuse interacted to predict depressive symptoms eight months later, controlling for initial depressive symptoms. Specifically, emotional abuse predicted increases in depressive symptoms among Caucasian adolescents with more OGM, but not among those with less OGM. This association was not significant for African American adolescents. These results provide support for a cognitive vulnerability-stress relationship between OGM and emotional abuse in early adolescence and suggest that these mechanisms of risk for depression may be specific to Caucasian adolescents.

According to the stress generation hypothesis (Hammen, 1991), depressed and depression-prone individuals experience higher rates of negative life events influenced by their own behaviors and characteristics (i.e., dependent events), which in part may account for the often recurrent nature of depression. Relatively little is known about the interrelation between stress generation predictors, and distal risk factors for this phenomenon. This study examined whether childhood emotional, sexual, and physical abuse, each uniquely predicted negative dependent events in individuals with a history of depression. The role of negative inferential styles as a potential mediator was also assessed. A sample of 66 adults with a history of depression completed self-report measures of childhood abuse history and negative inferential styles at baseline. The "contextual threat" method was used to assess the occurrence of negative life events over a 4-month prospective follow-up period. Childhood emotional abuse, but not sexual or physical abuse, prospectively predicted greater stress generation. Negative inferential styles mediated this relation. These findings suggest that targeting negative cognitive styles in clinical settings, especially in patients with a history of childhood emotional abuse, may be important for reducing the occurrence of negative life events, thereby possibly decreasing risk for depression recurrence.
