An abbreviated PTSD checklist for use as a screening instrument in primary care

Although the importance of recognizing posttraumatic stress disorder (PTSD) in primary care has been well-established, routine screening for PTSD remains unfeasible for many primary care clinics because of the length of the available screening instruments. Thus, the purpose of this work was to develop and validate a brief screening tool for PTSD. In Study 1, four short forms of the PTSD Checklist-civilian version were identified that captured a majority of the variance in the measure. In Study 2, the performance of these short forms was evaluated in a separate sample of primary care patients. We found that both two-item and six-item versions have adequate psychometric properties for screening purposes and suggest that the selection of one version over the other depends on the specific needs of each primary care clinic.     

Verbal Abilities in Low and Highly Proficient Bilinguals

The study investigated native language verbal skills among low and highly proficient bilinguals, using the WISC III verbal subtests. Highly proficient bilinguals showed a superiority for almost all verbal subtests. This finding lends support to Threshold Theory which maintains that bilinguals need to achieve high levels of linguistic proficiency before bilingualism can promote cognitive development. Our study also shows that verbal ability underlying proficiency in the native language can be generalized to a foreign language, revealing a causal connection between native and foreign language learning.     

From sensory processes to conscious perception

In recent years, cognitive neuroscientists have began to explore the process of how sensory information gains access to awareness. To further probe this process, event-related functional magnetic resonance imaging (fMRI) was used while testing subjects with a paradigm known as the "attentional blink." In this paradigm, visually presented information sporadically fails to reach awareness. It was found that the magnitude and time course of activation within the anterior cingulate (BA 32), medial prefrontal cortex (BA 9), and frontopolar cortex (BA 10) predicted whether or not information was consciously perceived during the critical period for the attentional blink. These results are discussed in light of a neural framework for conscious processing.     

The relationship between interpersonal perception and post-traumatic stress disorder-related functional impairment: a social relations model analysis

This study used Kenny's social relations model to examine the relationship between Post-Traumatic Stress Disorder-related impairment and interpersonal perceptions. Participants were 124 students who had previously completed the Post-traumatic Stress Diagnostic Scale as part of a larger study. After engaging in brief dyadic conversations with 3 other students, participants recorded perceptions of personality traits for themselves, their interaction partners and how they believed their partners saw them (metaperceptions). Results indicated that those with more severe post-traumatic stress disorder-related impairment saw themselves negatively and believed their interaction partners also viewed them negatively. However, these individuals were not seen differently by others, except that they were rated as less dependable. Our findings suggest that post-traumatic stress disorder is associated with negative beliefs about the self that may influence self-esteem and interpersonal relationships.     

Prevalence of Child and Adolescent Exposure to Community Violence

Emerging as one of the most significant health issues facing American youth today, child and adolescent exposure to community violence has generated much interest across multiple disciplines. Most research to date has focused on documenting the prevalence of community violence and the emotional and behavioral ramifications. This paper provides an overview of the current literature regarding prevalence of youth exposure to community violence, and identifies those areas where further research is warranted. In addition to examining overall rates of community violence exposure, this paper reviews the prevalence of different types of community violence, such as weapon use, physical aggression, and crime-related events. Predictors of community violence exposure, including gender, age, race, socioeconomic status, behavior patterns, and geography, are discussed.     

Body attitudes and body experiences in suicidal adolescents

The relationships between cognitive and affective attitudes toward the body, body experiences (dissociation, insensitivity, and lack of control), and suicidal tendencies were examined as a derivative of the hypothesis that bodily attitudes and experiences may facilitate suicidal acting out. Three groups of adolescents (aged 14-18), including suicidal (made a suicide attempt) and nonsuicidal inpatients and controls, were compared with regard to suicidal tendencies, various body aspects, and depression and anxiety. A series of MANOVAs, discriminant analysis, Pearson correlations, and regressions were employed. The results show that the suicidal group differed from the two nonsuicidal groups in feelings toward the body, body protection, and body dissociation. Some aspects of bodily measures discriminated between suicidal and nonsuicidal subjects. In addition, various bodily measures were associated with and statistically predicted suicidal tendencies. The discussion focuses on the web of associations between body attitudes and experiences and their role in suicidal behavior.     

A model for brief assessment of attachment and its application to women in inpatient treatment for trauma-related psychiatric disorders

We adapted self-report measures of attachment style to the psychological assessment of women in specialized inpatient treatment for trauma-related disorders. The study employed 2 measures of adult attachment style, the Relationship Questionnaire (Bartholomew & Horowitz, 1991) and the Adult Attachment Scale (Collins & Read, 1990) as well as our Current Attachment Relationships questionnaire, which assesses the extent of social support in secure attachments. We administered these measures to 99 patients and to a convenience sample of 154 women in the community. We found modest correspondence between the 2 attachment style measures and substantial relations between attachment styles and range of secure attachment relationships. Women in the trauma sample reported insecure attachment styles and relatively few secure attachment figures. We discuss the implications of these findings for clinical assessment.     

Parentification and its impact on adolescent children of parents with AIDS.

Parentification refers to children or adolescents assuming adult roles before they are emotionally or developmentally ready to manage those roles successfully. We assess predictors and outcomes of parentification among adolescent children of Parents with AIDS (PWAs) in two phases. In Phase 1, relationships among parental AIDS-related illness, parent drug use, parent and adolescent demographics, and parentification indicators (parental, spousal, or adult role-taking) were assessed among 183 adolescent-parent pairs (adolescents: 11 to 18 years, M = 14.8 years, 54% female; parents: 80% female). Adult role-taking was associated with maternal PWAs, female adolescents, and greater parent drug use. Greater parental AIDS-related illness predicted more spousal and parental role-taking. Parent drug use predicted more parental role-taking. In Phase 2, we examined the impact of parentification on later adolescent psychological adjustment (N = 152 adolescents). Adult role-taking predicted more internalized emotional distress; parental role-taking predicted externalized problem behaviors: sexual behavior, alcohol and marijuana use, and conduct problems. Given these dysfunctional outcomes, we discuss interventions to mitigate parentification among children of PWAs.
