The detection and management of mental health disorders in pediatric primary care

We reviewed the literature on the detection and management of mental health disorders within the context of pediatric primary care. Pediatricians have displayed a low sensitivity and high specificity in research investigating the detection of mental health impairment in children. Active management efforts characterize approaches to identified cases with more recently trained primary care pediatricians displaying a wider range of skills in managing mental health disorders. Few efforts have been made by pediatric psychologists to develop strategies for enhancing detection rates and management or to empirically evaluate the integration of pediatric psychology services into the primary care context. A conceptual model of factors influencing detection rates and ongoing management of mental health disorders within pediatric primary care is presented. Recommendations are made for more direct involvement of pediatric psychologists within the primary care context.     

Non-heart-beating organ donation: a reply to Campbell and Weber.

In the preceding commentary, Campbell and Weber raise two valid and important issues concerning non-heart-beating organ donation (NHBOD). First, because the procedure links withdrawal of life support and the potential for subsequent organ donation, the desire for organs may create a situation in which care of the dying individual has relatively less importance and the dying may receive suboptimal care. Second, even if concerns about care of the dying were dealt with adequately, there will not be enough non-heart-beating donors to significantly decrease the organ shortage that exists, making the procedure not worth the risk. We agree that attention to the important details of caring for the dying are, and must be, the primary concern of all health care workers caring for those individuals. Ensuring the patients' comfort, dignity, and autonomy, and providing for family and social support are the mainstays of this care. All policies for NHBOD should clearly support and mandate these concepts. Regarding the second concern, we agree that NHBOD is currently rare; however, evidence is increasing that this type of donation has great potential. Continued growth of the practice in this country will depend largely on public acceptance, which we believe will be directly influenced by whether the public perceives that care of the dying is not compromised by this procedure.     

Parenting stress in parents of children with attention-deficit hyperactivity disorder and parents of children with learning disabilities

Parenting a child with ADHD can challenge parenting resources and coping. Increasingly, researchers are examining the relationship between the behavior of the child with ADHD and family functioning. While studies have shown inceased parenting stress in parents of children with ADHD, these studies have compared children with ADHD to non-disabled children. This study compares reports of parenting stress among mothers of children with ADHD, mothers of children with learning disabilities and mothers of non-referred children. Results showed that parenting stress was highest for mothers of children with ADHD. Increased parenting stress was associated with child characteristics and, in particular, with externalizing behavior problems.     

On “knowing your partner”: Dangerous illusions in the age of AIDS?

We identified two characteristics of the impression formation process that may cause people to underestimate the riskiness of potential sexual partners. In Study 1, participants were quite confident that they could determine whether someone was lying to them about risk-related behavior when, in reality, they could not. Particularly troubling was a “truth bias” that resulted in relatively high rates of truth detection, but poor lie detection. In Study 2, increased familiarity with a target person (who actually was HIV+) caused participants to lower their estimates of the target's riskiness, despite the fact that we explicitly warned them that the target might be HIV+. We suggest that such processes may foster the illusion of knowing one's partner when one does not.     

Suffering, sovereignty, and the purposes of God: Christian convictions and medical killing.

Despite a variety of "non-ecumenical" features in Christian arguments about suicide, assisted suicide, and euthanasia, there are obvious "ecumenical" aspects to be found in the general Christian prohibition of these practices. A fair reading of the Christian tradition requires that we acknowledge both the differences that distinguish particular perspectives and the fundamental themes that allow an identifiably Christian position to emerge in stark contrast to the secular discussion of these issues. Central to Christian interpretations of dying and death are an acknowledgment of God's sovereignty over human life, an understanding of suffering that stresses identification with Christ as the source of Christian hope, and the recognition that God's creative and redemptive purposes are generally (or always) at odds with the deliberate choice of assisted suicide or euthanasia.     

The box alignment illusion: An orientation illusion induced by pictorial depth

In four experiments, observers attempted to align two sets of oblique edges to parallel. The contexts for these alignments included lines in isolation (2-D control), lines embedded in orthogonal drawings of same-oriented and different-oriented boxes (3-D objects), and each of these viewed against backgrounds depicting strong linear perspective (3-D backgrounds). A consistent distortion was observed in the alignments of different-oriented boxes relative to control lines, indicating that the parallel lines in these stimuli appeared to diverge toward the top of the picture. Furthermore, thisbox alignment illusion decreased with interstimulus distance, whereas alignment distortions in control lines and same-oriented boxes increased with distance. Viewing the stimuli against 3-D backgrounds produced a dramatic reversal of the illusion, with control lines now appearing to converge more than the boxes. These results suggest that the illusion reflects basic processes involved in pictorial depth perception.

Use of a computer-controlled firearms training simulator in perception response time experiments

This paper describes the use of a custom-configured computer-controlled firearms training simulator to measure perception response (reaction) time (RT) to a stimulus in which the degree of threat presented is a manipulable variable across trials. The computer records the number of frames of videotape traversed between the point of presentation of the threat in the video stimulus and the point at which the subject responds by drawing the firearm. For the purposes of data analysis, these frame-count measures are converted to RT measurements. Example data are presented that capture perception RT at both thedraw-stimulus and thefire-stimulus points in situations for which either only one threat or more than one threat exists. Other elements, such as degree of threat and accuracy of response, provide additional data.     

Computer games: Paradigms of opportunity

Computer games offer unique opportunities to apply unobtrusive constraints to action that permit meaningful analysis without destroying the integrity of the game itself. To a much greater extent than most traditional laboratory tasks, computer games represent holistic, meaningful, and natural human activity. Considerable concern about the appropriate analysis and interpretation of results, however, remains. One strategy that addresses these concerns involves the adoption of separate but convergent analytic perspectives. This article suggests that three such perspectives (viz., the objective, the subjective, and the empirical) can be combined to provide the necessary logical leverage to allow meaningful research. Alternative analyses of data collected from the playing of a particular arcade-type computer game are used to illustrate this point.
