Tumor Locus Moderates Anxiety Symptoms in a Pediatric Neuro-Oncologic Sample

Despite the prevalence of pediatric Central Nervous System (CNS) solid tumors, little is understood about patients' disease-related anxiety experience. Data from 25 remitted pediatric CNS tumor patients posttreatment were collected. Significant symptoms of anxiety were reported by 32% of patients. MRI studies showed all anxious patients had right cortical tumors or left cerebellar tumors. Confound analyses suggest these results are not better accounted for by demographic, disease, or treatment variables. These results evidence the risk some pediatric neuro-oncologic patients face for developing significant anxiety symptoms.     

Parents and divorce: Identifying the support network for decisions about custody

Abstract

The social support network of divorcing parents has been identified as an important factor in postdivorce adjustment. The present study examined the social resources accessed by parents regarding issues of custody and visitation. Parents' evaluation of and interest in participating in four types of custody-related interventions (workshops, mediation, professional evaluation, and arbitration) were also examined. The findings and their implications for clinical practice suggest some major shifts in the provision of services for divorcing families.     

Therapy with law enforcement couples: Clinical management of the “high-risk lifestyle”

Abstract

A great deal of attention has been given to the issue of stress in law enforcement and its impact on individual officers. However, the literature has not equally addressed the effects of police work on officers' relationships. This paper reviews three primary ways in which law enforcement can affect relationships (organizational influences, peer/socialization influences, and police role influences). It identifies some common difficulties encountered by these couples, and provides some basic goals and strategies for engaging them in treatment and addressing these issues in couples therapy.     

Mortality Salience and Perceptions of People with AIDS: Understanding the Role of Prejudice

Study 1 examined the perceived association of AIDS and death by showing that thinking about AIDS increased participants'; death-thought accessibility. Hypotheses about the consequences of this association for perceptions of people with AIDS were derived from terror management theory, which proposes that mortality salience increases derogation of those who threaten people's worldviews unless those worldviews oppose prejudice, in which case mortality salience can increase acceptance of people who are otherwise threatening. Consistent with these hypotheses, conservative participants had less favorable impressions (Study 2) and liberal participants had more favorable impressions (Study 3) of a target with AIDS following a death reminder. Study 4 suggested that the decrease in prejudice among liberals following mortality salience was a genuine decrease in prejudice (as indicated by responses to an unobtrusive attitude measure), not just an increase in the desire to appear nonprejudiced. Theoretical and practical implications of these findings are discussed.     

Bootstrapping Processes in the Development of Students' Commonsense Matter Theories: Using Analogical Mappings,Thought Experiments,and Learning to Measure to Promote Conceptual Restructuring

This study explores whether the development of students' understanding of matter as something that occupies space and has weight involves conceptual change and restructuring rather than only simple belief revision. Based on an analysis of how the concepts in students' initial matter theory (henceforth MT1) may differ from the concepts in the matter theory that is a target of middle school instruction (MT2), I propose ways that concepts in a given theory cohere with each other and identify the sources of the new ideas in MT2 and the learning processes by which those new ideas can be acquired. I test implications of these analyses by designing a curriculum unit that exploits these learning mechanisms, by using the curriculum with 4 classes of eighth-grade Earth Science students, and by assessing 42 students' thinking about matter, object size, and weight (via individual interviews and written tests) before and after the teaching unit. Consistent with the hypothesis of conceptual restructuring, the data not only show coherencies in students' thinking about matter, size, and weight before and after teaching, but also coordinated patterns of change. The implications for the design of science instruction are discussed.     

Does the "eyes lead the hand" principle apply to reach-to-grasp movements evoked by unexpected balance perturbations?

A fundamental principle that has emerged from studies of natural gaze behavior is that goal-directed arm movements are typically guided by a saccade to the target. In this study, we evaluated a hypothesis that this principle does not apply to rapid reach-to-grasp movements evoked by sudden unexpected balance perturbations. These perturbations involved forward translation of a large (2 × 6 m) motion platform configured to simulate a “real-life” environment. Subjects performed a common “daily-life” visuo-cognitive task (find a telephone and make a call) that required walking to the end of the platform, which was triggered to move as they approached a handrail mounted alongside the travel path. A deception was used to ensure that the perturbation was truly unexpected. Eleven of 18 healthy young-adult subjects (age 22-30) reached to grasp or touch the rail in response to the balance perturbation. In support of the hypothesis, none of these arm reactions was guided by concurrent visual fixation of the handrail. Seven of the 11 looked at the rail upon first entering the environment, and hence may have used “stored” central-field information about the handrail location to guide the subsequent arm reaction. However, the other four subjects never looked directly at the rail, indicating a complete reliance on peripheral vision. These findings add to previous evidence of distinctions in the CNS control of volitional and perturbation-evoked arm movements. Future studies will determine whether similar visuo-motor behavior occurs when the available handhold is smaller or when subjects are not engaged in a concurrent visuo-cognitive task.     

Convergence of scores on the interview and questionnaire versions of the Eating Disorder Examination: a meta-analytic review

Significant discrepancies have been found between interview- and questionnaire-based assessments of psychopathology; however, these studies have typically compared instruments with unmatched item content. The Eating Disorder Examination (EDE), a structured interview, and the questionnaire version of the EDE (EDE-Q) are considered the preeminent assessments of eating disorder symptoms and provide a unique opportunity to examine the concordance of interview- and questionnaire-based instruments with matched item content. The convergence of EDE and EDE-Q scores has been examined previously; however, past studies have been limited by small sample sizes and have not compared the convergence of scores across diagnostic groups. A meta-analysis of 16 studies was conducted to compare the convergence of EDE and EDE-Q scores across studies and diagnostic groups. With regard to the EDE and EDE-Q subscale scores, the overall correlation coefficient effect sizes ranged from .68 to .76. The overall Cohen's d effect sizes ranged from .31 to .62, with participants consistently scoring higher on the questionnaire. For the items measuring behavior frequency, the overall correlation coefficient effect sizes ranged from .37 to .55 for binge eating and .90 to .92 for compensatory behaviors. The overall Cohen's d effect sizes ranged from -0.16 to -0.22, with participants reporting more binge eating on the interview than in the questionnaire in 70% of the studies. These results suggest the interview and questionnaire assess similar constructs but should not be used interchangeably. Additional research is needed to examine the inconsistencies between binge frequency scores on the 2 instruments.     

Community norms about suppression of AIDS-related prejudice and perceptions of stigma by people with HIV or AIDS

We investigated the relationship between community motivations to control AIDS-related prejudice and the experience of stigma by community members with HIV or AIDS, using self-reports from 203 New England residents with HIV or AIDS and 2,444 randomly selected residents of the same New England communities. Multilevel regression analyses revealed that the disclosure concerns of participants with HIV or AIDS were lower in communities where residents were motivated by personal values to control AIDS-related prejudice, and were higher in communities where residents were motivated by social pressure to control AIDS-related prejudice. Reported experiences with discrimination and exclusion were unrelated to community motivations. The results of our study suggest that external and internal pressures to control prejudice shape the experience of stigmatization.     

Dealing with the long-term social implications of research

Biomedical and behavioral research may affect strongly held social values and thereby create significant controversy over whether such research should be permitted in the first place. Institutional review boards (IRBs) responsible for protecting the rights and welfare of participants in research are sometimes faced with review of protocols that have significant implications for social policy and the potential for negative social consequences. Although IRB members often raise concerns about potential long-term social implications in protocol review, federal regulations strongly discourage IRBs from considering them in their decisions. Yet IRBs often do consider the social implications of research protocols and sometimes create significant delays in initiating or even prevent such research. The social implications of research are important topics for public scrutiny and professional discussion. This article examines the reasons that the federal regulations preclude IRBs from assessing the social risks of research, and examines alternative approaches that have been used with varying success by national advisory groups to provide such guidance. The article concludes with recommendations for characteristics of a national advisory group that could successfully fulfill this need, including sustainability, independence, diverse and relevant expertise, and public transparency.
