A prospective study of appraisals in childhood posttraumatic stress disorder

This study investigated the predictors of posttraumatic stress disorder (PTSD) in children following a diagnosis of traumatic injury. Children (N=76) aged between 7 and 13 who were admitted to hospital following injury were assessed within a month of trauma for acute stress disorder (ASD), negative appraisals, as well as parental stress reactions. Children (N=62) were re-assessed 6-months later for PTSD and negative appraisals. The majority of the variance of chronic posttraumatic stress was accounted for by negative appraisals about future harm. This study supports cognitive models of PTSD, and suggests that younger children who exaggerate their vulnerability after trauma exposure are high risk for PTSD after trauma.     

Does providing props during preparation help children to remember a novel event?

We investigated the conditions under which preparatory information presented 1 day before a novel event influenced 6-year-olds' recall 1 week later. Children were assigned to one of six experimental conditions. Three conditions involved preparatory information that described the event accurately but differed according to the presence and type of props (verbal, real props, and toy props). In two conditions, which also differed according to whether verbal information was supplemented with real props, half of the preparatory information described the event accurately, whereas the other half was thematically similar to, but inconsistent with, the event (misleading verbal and misleading props). Compared with the attentional control condition, all forms of preparation that described the event accurately increased correct recall. Preparation that included props improved photograph recognition. When half of the accurate information was replaced by misleading information, the positive benefit on recall was reduced, and when misleading props accompanied the misleading information, errors increased. The potential underlying mechanisms and implications for pediatric settings are discussed.     

Mindfulness Meditation for Symptom Reduction in Fibromyalgia: Psychophysiological Correlates

Objectives Fibromyalgia, a chronic pain syndrome, is often accompanied by psychological distress and increased basal sympathetic tone. In a previous report it was shown that mindfulness-based stress-reduction (MBSR) reduced depressive symptoms in patients with fibromyalgia with gains maintained at two months follow-up (Sephton et al., Arthr Rheum 57:77–85, 2007). This second study explores the effects of MBSR on basal sympathetic (SNS) activation among women with fibromyalgia. Methods Participants (n = 24) responded to a television news appearance, newspaper, and radio advertisements. Effects on anxiety, depressive symptoms, and SNS activation measures were tested before and after MBSR using a within-subjects design. Results The MBSR treatment significantly reduced basal electrodermal (skin conductance level; SCL) activity (t = 3.298, p = .005) and SCL activity during meditation (t = 4.389, p = .001), consistent with reduced SNS activation. Conclusions In this small sample, basal SNS activity was reduced following MBSR treatment. Future studies should assess how MBSR may help reduce negative psychological symptoms and attenuate SNS activation in fibromyalgia. Further clarification of psychological and physiological responses associated with fibromyalgia may lead to more beneficial treatment.     

The ethics of punishment: Correctional practice implications

Correctional practitioners work within a context that is heavily influenced and constrained by punishment policies and practices. The overlap between the normative frameworks of punishment and offender rehabilitation creates a unique set of ethical challenges for program developers and therapists. In this paper we set out to briefly outline three major punishment theories and draw out their implications for correctional practitioners. First, we discuss the nature of punishment and the problems it poses for practitioners and all citizens in liberal democracies. Second, consequential, retributive, and communicative justifications of punishment are succinctly described and their clinical implications analyzed and some limitations noted. Finally we conclude with some suggestions for ethical practice in correctional settings.     

Torque,lateral preference,and cognitive ability in primary-grade children

It has been suggested that torque, the tendency to draw circles in the clockwise direction, is related to left-handedness and is a marker for psychopathology. Results of recent studies conflict with this hypothesis hut are weakened by imprecise definition and unreliable assessment of torque. Measures of torque, lateral preference, and cognitive ability were administered to 181 children in kindergarten and first grade. As reported previously, rate of torque decreased with age and was greater among males. Children with complete clockwise or counter-clockwise circling at both assessments differed in pattern but not in overall level of cognitive ability No differences were found in strength, direction, or concordance of hand and foot preference. Results of this and other studies are seen as inconsistent with proposals that torque is symptomatic of psychopathology.     

The futures of physicians: Agency and autonomy reconsidered

The corporatization of U.S. health care has directed cost containment efforts toward scrutinizing the clinical decisions of physicians. This stimulated a variety of new utilization management interventions, particularly in hospital and managed care settings. Recent changes in fee-for-service medicine and physicians' traditional agency relationships with patients, purchasers, and insurers are examined here. New information systems monitoring of physician ordering behavior has already begun to impact on physician autonomy and the relationship of physicians to provider organizations in both for-profit and ‘not-for-profit’ sectors. As managed care practice settings proliferate, serious ethical questions will be raised about agency relationships with patients. This article examines health system dynamics altering the historical agency relationship between the physician and patient and eroding the traditional autonomy of the medical profession in the United States. The corporatization of medicine and the accompanying information systems monitoring of physician productivity is seen to account of such change, now posing serious ethical dilemmas.

Do Overgeneral Autobiographical Memories Predict Increased Psychopathological Symptoms in Community Youth? A 3-Year Longitudinal Investigation

Research suggests that an overgeneral autobiographical memory style (i.e., retrieval of general memories when instructed to retrieve a specific episodic memory) represents a vulnerability marker for depression. Although adolescence is a period of high risk for the emergence of depression, little research has investigated the associations among overgeneral memory, psychopathology, and risk factors longitudinally in a community sample in this age group. We, therefore, investigated overgeneral memory, psychopathology (depression and anxiety), and rumination (an established risk factor for psychopathology) longitudinally in 269 typically-developing youth (125 females, 144 males) across 3 annual assessment points. We sought to determine whether 1) overgeneral memory would predict psychopathology across the entire sample, and 2) whether associations would vary as a function of longitudinal rumination growth. Across the entire sample, overgeneral memory did not predict psychopathology. For youth who reported elevated, and increasing, patterns of rumination over time, transient relationships between overgeneral memory and subsequent increases in anxiety were found. We conclude that overgeneral memory may represent a vulnerability marker for adverse psychological outcomes only for youth at risk for psychopathology.     

The effects of motion on in-vehicle touch screen system operation: A battle management system case study

The use of in-vehicle touch screen devices is currently common in both military and civilian vehicles; despite this, the effects of motion on touch screen device operation within vehicles remains largely unexplored. This article describes a study that examined, using driving simulation, the influences of motion on performance, workload and usability when using a touch screen in-vehicle battle management system. Acting in the role of battle management system operator, 20 participants undertook four simulated drives, two under high motion (representative of an unsealed road) and two under normal motion (representative of a sealed road), whilst performing various battle management tasks. In the high motion condition, lower accuracy and longer task completion times were found, along with greater levels of subjective and physiological workload and lower levels of perceived device usability, when compared to the normal motion condition. The findings indicate that, compared to normal motion, the high motion condition impaired key aspects of battle management system operation. In closing, the importance of considering motion and its effects during touch screen system design is discussed.
