Gender Differences in Trauma Types and Themes in Veterans with Posttraumatic Stress Disorder

Background: This study aimed to determine whether there were gender differences in trauma types and cognitive-emotional themes among veterans with deployment-related posttraumatic stress disorder (PTSD). Methods: Case notes or writing excerpts from two pilot studies were reviewed to determine types of traumas and emerging themes, with 20 women and 31 men comprising the sample. Results: Most women developed PTSD after sexual assault, with reactions emphasizing mistrust, betrayal, and anger. Men experienced more combat, with reactions including survivor guilt, moral injury, and horror. Conclusions: Both genders developed PTSD, but the causes of and reactions to their traumas differed. Emerging themes can be useful treatment foci.     

Understanding the centrality deficit: Insight from foreign language learners

This study replicated and extended a phenomenon in the text memory literature referred to as the centrality deficit Miller & Keenan (Annals of Dyslexia 59:99–113, 2009). It examined how reading in a foreign language (L2) affects one’s text representation and ability to recall the most important information. Readers recalled a greater proportion of central than of peripheral ideas, regardless of whether reading in their native language (L1) or a foreign language (L2). Nonetheless, the greatest deficit in participants’ L2 recalls, as compared with L1 recalls, was on the central, rather than the peripheral, information. This centrality deficit appears to stem from resources being diverted from comprehension when readers have to devote more cognitive resources to lower level processes (e.g., L2 word identification and syntactic processing), because the deficit was most evident among readers who had lower L2 proficiency. Prior knowledge (PK) of the passage topic helped compensate for the centrality deficit. Readers with less L2 proficiency who did not have PK of the topic displayed a centrality deficit, relative to their L1 recall, but this deficit dissipated when they did possess PK.     

Emotional Dysregulation and Interpersonal Difficulties as Risk Factors for Nonsuicidal Self-Injury in Adolescent Girls

The purpose of this study was to examine a model of factors that place psychiatrically hospitalized girls at risk for non-suicidal self-injury (NSSI). The role of familial and peer interpersonal difficulties, as well as emotional dysregulation, were examined in relationship to NSSI behaviors. Participants were 99 adolescent girls (83.2% Caucasian; M age = 16.08) admitted to a psychiatric hospital. Structural equation modeling indicated the primacy of emotional dysregulation as an underlying process placing adolescents at risk for NSSI and mediating the influence of interpersonal problems through the family and peer domains. When family and peer relationships were characterized by conflict and lack of support for managing emotions, adolescents reported more dysregulated emotion processes. Family relational problems were directly and indirectly related to NSSI through emotional dysregulation. The indirect processes of peer relational problems, through emotional dysregulation, were significantly associated with NSSI frequency and severity. The findings suggest that the process by which interpersonal difficulties contribute to NSSI is complex, and is at least partially dependent on the nature of the interpersonal problems and emotion processes.     

The relationship of childhood trauma to nicotine dependence in pregnant smokers

Pregnant women with high levels of nicotine dependence are the least likely to quit smoking spontaneously during pregnancy or to benefit from smoking cessation interventions. In the general population, there is increasing evidence of a relationship between smoking, nicotine dependence, and exposure to childhood trauma. We examined the relationship of childhood trauma to several measures of nicotine dependence and evaluated whether this relationship was mediated by major depressive disorder or depressive symptom severity in pregnant smokers. Moderate to extreme levels of childhood trauma were significantly related to smoking within 5 minutes or less of waking, and to the Behavioral Choice-Melioration, Negative Reinforcement, and Tolerance subscales of the Wisconsin Inventory of Smoking Dependence Motives (WISDM-68) scale. The relationships between childhood emotional abuse and the WISDM-68 Total and Negative Reinforcement subscale were partially mediated by depressive symptoms. Results suggest that childhood trauma may be a risk factor underlying nicotine dependence in pregnant smokers. Increased understanding of the relationship of affect regulation to smoking in individuals with childhood trauma histories may aid in the development of more effective treatments of nicotine dependence for this population of smokers.     

Dimensions and Correlates of Attention Deficit/Hyperactivity Disorder and Sluggish Cognitive Tempo

The present study examined Sluggish Cognitive Tempo (SCT) in relation to ADHD symptoms, clinical diagnosis, and multiple aspects of adjustment in a clinical sample. Parent and teacher reports were gathered for 322 children and adolescents evaluated for behavioral, emotional, and/or learning problems at a university clinic. Confirmatory factor analyses (CFA) supported the presence of three separate, but correlated factors (SCT, inattention, and hyperactivity/impulsivity) in both parent and teacher ratings. As expected, SCT symptoms were greatest in youth with ADHD Inattentive type, but were also found in non-ADHD clinical groups. SCT symptoms were related to inattention, internalizing, and social problems across both parent and teacher informants; for parent reports, SCT was also related to more externalizing problems. Findings support the statistical validity of the SCT construct, but its clinical utility is still unclear.     

Is inclusion a valid control for ostracism?

Considerable knowledge about ostracism’s impact comes from research using Cyberball, an online ball-tossing game. In Cyberball, the inclusion condition is the control condition, to which ostracism is compared. The assumption is that Cyberball-inclusion is not affirming and represents an expected level of inclusion. However, without a no-inclusion control condition, it is unclear whether inclusion elevates need satisfaction, whether ostracism depresses need satisfaction, or both. We introduce Cybertree—a control condition designed to provide a similar experience to Cyberball without inclusion. Individuals playing Cybertree did not differ from included individuals in terms of feeling ostracized, level of need satisfaction, and mood. Both Cyberball inclusion and Cybertree differed significantly from ostracized individuals. We conclude that Cyberball inclusion is a reasonable control group for Cyberball ostracism but discuss research questions that may benefit from the use of Cybertree.     

An Analysis of Content and Instructional Strategies in Multicultural Counseling Courses

The authors present a content analysis of syllabi from introductory multicultural counseling training (MCT) courses. Results suggest that these courses focus on knowledge of other cultural groups, emphasize the cultural identity exploration of the student at a lower level of training, and almost completely ignore the development of skills. The study revealed that MCT frequently includes groups beyond racial and ethnic minority groups. A broad range of instructional strategies are used, with a handful being used on a frequent basis. Los autores presentan un análisis del contenido de planes de estudios empleados en cursos introductorios de formación en consejería multicultural (MCT, por sus siglas en inglés). Los resultados sugieren que estos cursos se centran en el conocimiento de otros grupos culturales, enfatizan la exploración de la identidad cultural del alumno en los niveles iniciales de su formación e ignoran casi por completo el desarrollo de habilidades. El estudio reveló que la MCT incluye con frecuencia grupos aparte de las minorías raciales y étnicas. Se utiliza una amplia gama de estrategias didácticas, un puñado de las cuales se emplea frecuentemente.     

Early top-down influences on bistable perception revealed by event-related potentials

A longstanding debate exists in the literature concerning bottom-up vs. top-down influences on bistable perception. Recently, a technique has been developed to measure early changes in brain activity (via ERPs) related to perceptual reversals (Kornmeier & Bach, 2004). An ERP component, the reversal negativity (RN) has been identified, and is characterized as an increase in negative potential over the posterior scalp from 150 to 350 ms for perceptual reversals compared to perceptual stability. This finding, although interesting, has not helped resolve issues related to the bottom-up vs. top-down debate because top-down influences have not been directly manipulated. The current study focused on resolving some of these issues by measuring the RN while observers maintained one of three 'intentional approaches', (1) try to reverse perception as often as possible, (2) try to stabilize perception for as long as possible, and (3) maintain a passive approach. Enhancements in RN amplitude were found for the intention-to-reverse condition compared to the passive condition. This finding suggests an early influence (150 ms) of top-down control on perceptual reversals of bistable figures. Results are discussed in terms of competing attention shifting vs. fatigue-based theories of bistable perception.
