Neuropsychological Issues in the Assessment of Refugees and Victims of Mass Violence

Brain injury, stressor severity, depression, premorbid vulnerabilities, and PTSD are frequently intertwined in trauma populations. This interaction is further complicated when the neuropsychologist evaluates refugees from other cultures. In addition, the observed psychiatric symptoms reported in refugees and victims of mass violence may in fact not be the primary features of PTSD and depression but psychiatric symptoms secondary to the effects of traumatic brain injury. This paper reviews the occurrence of starvation, torture, beatings, imprisonment, and other head injury experiences in refugee and POW populations to alert treators to the presence of chronic and persistent neuropsychiatric morbidity, with implications for psychosocial adjustment. The concept of fixed neural loss may also interact with environmental and emotional stresses, and a model of neuropsychological abnormalities triggered by traumatic events and influenced by subsequent stress will also be considered. Neuropsychologists working with refugees play an important role in assessing the possibility of traumatic brain injury with tools that are relatively culture-fair.     

Remarkable properties for diagnostics and inference of ranking data modelling

The Plackett-Luce model (PL) for ranked data assumes the forward order of the ranking process. This hypothesis postulates that the ranking process of the items is carried out by sequentially assigning the positions from the top (most liked) to the bottom (least liked) alternative. This assumption has been recently relaxed with the Extended Plackett-Luce model (EPL) through the introduction of the discrete reference order parameter, describing the rank attribution path. By starting from two formal properties of the EPL, the former related to the inverse ordering of the item probabilities at the first and last stage of the ranking process and the latter well-known as independence of irrelevant alternatives (or Luce's choice axiom), we derive novel diagnostic tools for testing the appropriateness of the EPL assumption as the actual sampling distribution of the observed rankings. These diagnostic tools can help uncovering possible idiosyncratic paths in the sequential choice process. Besides contributing to fill the gap of goodness-of-fit methods for the family of multistage models, we also show how one of the two statistics can be conveniently exploited to construct a heuristic method, that surrogates the maximum likelihood approach for inferring the underlying reference order parameter. The relative performance of the proposals, compared with more conventional approaches, is illustrated by means of extensive simulation studies.     

On the technology of pastoral counseling

Formal pastoral counseling is developing as a significant and important counseling movement. Yet because of its historical tradition and current secular social climate, the pastoral counselor seems unable to translate theology and the religious model of suffering and illness into a concrete methodology of care-giving. This paper proposes that the priestly function or priest/rabbi/minister-parishioner relationship is a good place for the counselor to start identifying the religious methods and means of being with and caring for suffering individuals. The traditional practice of borrowing the psychology of the day is challenged as undermining pastoral counseling, as clergy men and women give up their own symbolic language for psychiatric jargon.Dr. Mollica will be a Fullbright Scholar at the University of Essex, Colchester, England, from August, 1977–May 1980.     

Repeated assessment of cognition in children and the measurement of performance change.

There is limited understanding of the problems associated with repeated neuropsychological assessment in children, including the statistics used to guide decisions about cognitive change. This study investigated the utility of a computerized assessment battery that was specifically designed for the repeated assessment of cognitive function in children. Eighty-seven participants aged 8 to 12 years completed the battery four times within a 2-hour testing session. The results support the application of this assessment battery for measuring cognitive change in children. A novel method for calculating measurement error is employed, and its use in the detection of cognitive change in individual children is discussed. An estimate of the measurement error within each of the tests is provided, and recommendations are made regarding the application of this assessment battery for measuring cognitive change in children.     

The influence of diversity context on white men's and racial minorities' reactions to disproportionate group harm

The author examined the influence of organizational diversity management on White men's and racial minorities' perceptions of fairness when members of their identity group were disproportionately harmed in a layoff. Using a scenario design, the author studied the reactions of 284 White male and racial minority layoff survivors under 2 different diversity contexts. White men saw the layoff as less fair to their group when other White men were laid off disproportionately in an active-diversity context versus an inactive-diversity context. Racial minorities' perceptions of fairness when other minorities were laid off disproportionately were not influenced by the diversity context, but they perceived the layoff as more fair to their group in an active-diversity context when White men were laid off disproportionately. The findings suggest that during layoffs or other significant organizational changes where job insecurity is heightened, different identity groups might perceive diversity management differently.
