Validity of the Personality Assessment Inventory Aggression Scales and Violence Potential Index in Veterans With PTSD

Examined humor appreciation of cartoons as a function of sex of subject and type of humor. Four broad types of humor were presented: sexual-exploitative, sexual-nonexploitative, nonsexual-hostile, and nonsexual-nonhostile. Sexual-nonexploitative humor was rated as funnier than the other three types but nonsexual-nonhostile humor was given a more positive overall rating than the other types. Relative to males, females gave greater ratings of hostility to the cartoons and rated them less positively. Correlational analyses further suggested that females were not as affected as males by variations in sexuality, exploitation, and hostility. For males, greater ratings of sexuality were associated with greater funniness ratings while the reverse was true for greater ratings of hostility. Possible interpretations of these data were discussed.     

Learning,Attention, Writing,and Processing Speed in Typical Children and Children with ADHD,Autism, Anxiety,Depression, and Oppositional-Defiant Disorder

Learning, attention, graphomotor, and processing speed scores were analyzed in 149 typical control children and 886 clinical children with normal intelligence. Nonsignificant differences were found between control children and children with anxiety, depression, and oppositional-defiant disorder. Control children performed better than children with ADHD and autism in all areas. Children with ADHD and autism did not differ, except that children with ADHD had greater learning problems. Attention, graphomotor, and speed weaknesses were likely to coexist, the majority of children with autism and ADHD had weaknesses in all three areas, and these scores contributed significantly to the prediction of academic achievement.     

Coping with Crises: An Examination of the Impact of Traumatic Events on Religious Beliefs

The impact of traumatic events on empirical and metaphysical assumptions was examined, by comparing assumptions of a group of 25 persons who had recently experienced a major stressor with assumptions of a group of 25 persons who had not had such an experience. Each group was composed of 22 women and 3 men, with a mean age of 20 years. Participants completed written measures assessing level of adjustment, empirical world assumptions, religious motivation, and religious and spiritual experiences. Naturalistic interviews were conducted with the trauma group. The trauma group obtained significantly higher scores on symptoms of psychological distress but did not differ in evaluations of the empirical world as predictable, safe, or controllable. Interviews suggested that the metaphysical assumptions were not challenged by trauma; rather, they provided a framework for understanding and coping with trauma.     

Extracting Intrinsic Functional Networks with Feature-Based Group Independent Component Analysis

There is increasing use of functional imaging data to understand the macro-connectome of the human brain. Of particular interest is the structure and function of intrinsic networks (regions exhibiting temporally coherent activity both at rest and while a task is being performed), which account for a significant portion of the variance in functional MRI data. While networks are typically estimated based on the temporal similarity between regions (based on temporal correlation, clustering methods, or independent component analysis [ICA]), some recent work has suggested that these intrinsic networks can be extracted from the inter-subject covariation among highly distilled features, such as amplitude maps reflecting regions modulated by a task or even coordinates extracted from large meta analytic studies. In this paper our goal was to explicitly compare the networks obtained from a first-level ICA (ICA on the spatio-temporal functional magnetic resonance imaging (fMRI) data) to those from a second-level ICA (i.e., ICA on computed features rather than on the first-level fMRI data). Convergent results from simulations, task-fMRI data, and rest-fMRI data show that the second-level analysis is slightly noisier than the first-level analysis but yields strikingly similar patterns of intrinsic networks (spatial correlations as high as 0.85 for task data and 0.65 for rest data, well above the empirical null) and also preserves the relationship of these networks with other variables such as age (for example, default mode network regions tended to show decreased low frequency power for first-level analyses and decreased loading parameters for second-level analyses). In addition, the best-estimated second-level results are those which are the most strongly reflected in the input feature. In summary, the use of feature-based ICA appears to be a valid tool for extracting intrinsic networks. We believe it will become a useful and important approach in the study of the macro-connectome, particularly in the context of data fusion.     

Medical education in a community model of care: The future of medical education in a large academic community hospital

Profound changes in the practice of medicine have led to new demands on the profession and on the process of medical education. In recognition of the expanded role of a physician as a professional responsible for the welfare of individuals, Lehigh Valley Hospital has developed an ambitious, innovative Strategic Plan for Education. The plan entitled, Medical Education in a Community Model of Care, emphasizes the organizational importance of education in the hospital's achievement of its mission of community service. The Strategic Plan for Education is community focused. In addition to its primary role of serving its local community, the plan is intended as a educational model for organizations in other parts of the country.Preparation of this paper was supported by a grant from the Dorothy Rider Pool Health Care Trust.     

Teachers' causal attributions for a child's hyperactivity: race, socioeconomic status, and typicalness.

80 teachers and teachers-in-training responded to paragraphs describing a child as hyperactive. The race, socioeconomic status of the child, and the typicalness of the child's hyperactivity were systematically varied. Responses were affected by the described typicalness but not by the described race or sex.     

Reactions to the family of the suicide

The present study investigated reactions to the survivors of a family member's suicide. One hundred and twenty seven adults, members of a large urban Protestant church, responded to a newspaper account of a suicide in which the following factors were systematically varied: sex of the suicide, causal locus of the suicide, and whether the cause was prior or immediate to the suicide. The design was a 2 (sex of respondent) x 2 (sex of suicide) x 2 (locus of cause internal or external to the individual) x 2 (temporally remote cause or immediate cause). Results indicated a slight tendency for males to be somewhat more socially accepting of the surviving spouse of a suicide. There was also a significant interaction between sex of respondent x sex of the suicide, such that respondents indicated they would feel less tension in talking with the surviving family of a suicide of the same sex.     

Intrusive versus deliberate rumination in posttraumatic growth across US and Japanese samples

To examine the role of rumination in the aftermath of traumatic/stressful events, posttraumatic growth (PTG) and the four types of rumination (i.e., intrusive rumination soon after the event, intrusive rumination recently, deliberate rumination soon after the event, and deliberate rumination recently) were assessed retrospectively for participants from the USA (N=224) and Japan (N=431). The results from a hierarchical regression analysis revealed that the hypothesized relationships among the four types of rumination and PTG were largely supported. Intrusive rumination soon after the event was positively related to PTG but recent deliberate rumination most strongly predicted the current levels of PTG for both samples. Some evidence for cultural differences in the role of rumination in PTG was also observed. In the US sample, deliberate rumination recently was more important than the deliberate rumination in the immediate aftermath of the traumatic/stressful event, whereas in the Japanese sample, deliberate rumination both soon after and recently were positively related to PTG. The results illustrate the importance of considering rumination as multidimensional and as varying across time in its impact on PTG. Future directions and clinical implications were discussed.
