GENDER DIFFERENCES IN SELF-REPORTED POSTTRAUMATIC GROWTH: A META-ANALYSIS

A meta-analysis was conducted to examine the direction and magnitude of gender differences in self-reported posttraumatic growth. Results from 70 studies ( N  = 16,076) revealed a small to moderate gender difference ( g  = .27, 95% CI = .21 −.32), with women reporting more posttraumatic growth than men. Moderator analyses were then conducted to identify possible sources of these differences. The following moderators were examined: mean age of sample, measure used, nature of the stressful event, language of the measure, and type of sample (i.e., community samples, college students, or mixed). The only significant moderator was age, with women reporting incrementally more posttraumatic growth as the mean age of the sample increased ( B  = .004,  p  < .01,  SE  = .001,  Q  = 9.13). To check for publication bias, effect sizes were compared across published and unpublished research. The size of the gender difference was not significantly different between published ( g  = .30, 95% CI = .23 − .38) and unpublished ( g  = .22, 95% CI = .12 −.31) studies. The present findings indicate that modest, but reliable gender differences exist in posttraumatic growth even when unpublished data are included in the analyses. Possible explanations for these findings and suggestions for future research are discussed.     

The experience of altered states of consciousness in shamanic ritual: The role of pre-existing beliefs and affective factors

Much attention has been paid recently to the role of anomalous experiences in the aetiology of certain types of psychopathology, e.g. in the formation of delusions. We examine, instead, the top-down influence of pre-existing beliefs and affective factors in shaping an individual’s characterisation of anomalous sensory experiences. Specifically we investigated the effects of paranormal beliefs and alexithymia in determining the intensity and quality of an altered state of consciousness (ASC). Fifty five participants took part in a sweat lodge ceremony, a traditional shamanic ritual which was unfamiliar to them. Participants reported significant alterations in their state of consciousness, quantified using the ‘APZ’ questionnaire, a standardized measure of ASC experience. Participants endorsing paranormal beliefs compatible with shamanic mythology, and those showing difficulty identifying feelings scored higher on positive dimensions of ASC experience. Our findings demonstrate that variation in an individual’s characterisation of anomalous experiences is nuanced by pre-existing beliefs and affective factors.     

Validity rates of the Personality Assessment Inventory and the Minnesota Multiphasic Personality Inventory-2 in a VA Medical Center Setting

In this study, we compared protocol validity rates between the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) and the Personality Assessment Inventory (PAI; Morey, 1991) in a veteran population. Veterans (N=472) were administered both instruments as part of routine psychological evaluations. Profile validity was based on previously published criteria. When applying primary validity indicators, inpatients produced significantly fewer invalid PAI profiles (37%) than MMPI-2 profiles (63%). We found similar results among outpatients for which we considered 47% of MMPI-2 profiles invalid compared to only 21% of PAI profiles. When applying both primary and supplementary validity indicators, both inpatients and outpatients continued to produce fewer invalid PAI profiles than MMPI-2 profiles. We discuss factors that may be related to the differences in validity rates.     

Perceptions of the use of drugs--a cross-sectional analysis.

Samples of six specific groups were surveyed regarding their differential perceptions of the use of drugs. Current use was discussed in terms of comparisons of different groups' ratings of each group, comparisons of differential use of drugs by each group and comparisons between each groups' perception of its own use and its perception of use by other groups.     

Cross-Sectional Age Analysis of Sleep Problems in 2 to 17 Year Olds with ADHD Combined,ADHD Inattentive,or Autism

Sleep problems are common in autism and ADHD. No study has compared sleep problems by age in 2 to 17 year olds with autism versus ADHD-Combined versus ADHD-Inattentive type. Mothers rated 1415 youth with autism and 1041 with ADHD on 10 Pediatric Behavior Scale sleep items. Nighttime sleep problems were most severe in autism, followed by ADHD-Combined, and then ADHD-Inattentive. Difficulty falling asleep, restless during sleep, and waking during the night were the most common problems. Adolescents slept more at night than other age groups, and youth who slept more at night were sleepier during the day. Sleep problems declined with age, but correlations were small. In adolescence, 63% with autism, 53% with ADHD-Combined, and 57% with ADHD-Inattentive had difficulty falling asleep. Given that the majority of children in all age groups had one or more sleep problem, developmentally appropriate interventions are needed to address sleep difficulties and limit their adverse effects.

     

Brain activation patterns in response to complex triggers in the Word Association Test: results from a new study in the United States

C.G. Jung's theory of psychological complexes lies at the root of analytical psychology theory and practice. Functional magnetic resonance imaging (fMRI) provides a powerful tool to validate the theory of complexes and eludicate the neuropsychologic mechanisms underlying the unconscious activation of significant memories. In this study, using fMRI, we identify two brain circuits which are activated in response to complex triggering words. Circuit one involves brain regions involved in episodic memory and somatic (body) responses and the experience of uncertainty. A second circuit involves episodic memory, emotion, visual and language association, and semiotic meaning. Specific brain regions include the right prefrontal cortex, SMA cortex, left temporal cortex, and the caudate and cingulate. These brain circuits may be thought of as the biological form in which complexes are experienced. Implications for analytic psychology practice and theory are discussed.     

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.     

Aberrant paralimbic gray matter in criminal psychopathy

Psychopaths impose large costs on society, as they are frequently habitual, violent criminals. The pervasive nature of emotional and behavioral symptoms in psychopathy suggests that several associated brain regions may contribute to the disorder. Studies employing a variety of methods have converged on a set of brain regions in paralimbic cortex and limbic areas that appear to be dysfunctional in psychopathy. The present study further tests this hypothesis by investigating structural abnormalities using voxel-based morphometry in a sample of incarcerated men (N=296). Psychopathy was associated with decreased regional gray matter in several paralimbic and limbic areas, including bilateral parahippocampal, amygdala, and hippocampal regions, bilateral temporal pole, posterior cingulate cortex, and orbitofrontal cortex. The consistent identification of paralimbic cortex and limbic structures in psychopathy across diverse methodologies strengthens the interpretation that these regions are crucial for understanding neural dysfunction in psychopathy.
