Active Coping and Perceived Social Support Mediate the Relationship Between Physical Health and Resilience in Liver Transplant Candidates

Without a transplant, end-stage liver disease is associated with significant morbidity and mortality. Transplant candidates endure physical and psychological stress while awaiting surgery, yet little is known about the relationship between physical health and psychological resilience during the wait-list period. This study examined predictors of psychological resilience and mediators of the relationship between physical health and psychological resilience in liver transplant candidates. Wait-listed candidates (N?=?120) from a single Northeast transplant center completed assessments of physical functioning, coping, perceived social support, and resilience. Findings revealed that physical functioning, active coping, and perceived social support were positively associated with resilience; maladaptive coping was negatively associated with resilience. Perceived social support and active coping partially mediated the relationship between physical functioning and resilience. Transplant center care providers should promote active coping skills and reinforce the importance of effective social support networks. These interventions could increase psychological resilience among liver transplant candidates.     

A Social-Cognitive Model of Driver Aggression: Taking Situations and Individual Differences into Account

Aggressive driving is a phenomenon that has taken on tremendous significance in society. While the issue has been studied from perspectives of several disciplines, relatively few comprehensive empirical investigations have been conducted. This may be due, at least in part, to a scarcity of comprehensive theoretical works in the field, from which methodical research hypotheses could be derived. This paper reviews major extant theories of general aggression to offer a rationale for choosing a particular framework to apply to the topic of aggressive driving. The social-cognitive model of aggressive driving is recommended, as it takes into account wide-ranging cognitive, situational, and dispositional factors. Implications for future research are also considered.     

Prediction outcome probabilities as determinants of choice reaction time

In a two-stimulus two-response choice reaction time (RT) task in which Ss made stimulus predictions, the probability of a correct prediction was manipulated between Ss. The magnitude of the difference in RT to correctly and incorrectly predicted stimuli (i.e., the prediction outcome effect) was an increasing function of the probability of a correct prediction This finding was primarily due to a reliable decrease in RT to correctly predicted stimuli as the probability of a correct prediction increased, since RT to incorrectly predicted stimuli was not affected by prediction outcome probability. These results were interpreted as partially supporting a continuous expectancy notion which involves facilitory and inhibitory mechanisms winch are differentially influenced by the probability of a correct prediction.     

Group Leader-Recorder Relationship in a State Hospital: A Learning Tool

The process group for staff and trainees in institutional settings has become increasingly unpopular as a resource, although ironically, the need for such a group has grown. The author presents the idea that the process group is not used more often because of a general lack of understanding of the nature of such groups as well as a failure to clearly distinguish process groups from traditional psychotherapy groups. The author goes on to give a clear definition of the task and the boundaries of a process group and, using knowledge of systems thinking, discusses special techniques for running such groups with illustrative examples.     

Pregnancy as a stressful life event

Pregnancy and childbirth typically are associated with positive emotions and with motherhood, but the reality is that this is not the case for all women or for all pregnancies. This review addresses a different aspect of these reproductive events, focusing on stressful circumstances surrounding pregnancy, as well as times when the pregnancy itself becomes a stressful life event. Pregnancy-related topics that tend to receive less attention will be emphasized. These include issues related to infertility; unplanned pregnancy; stress associated with testing and diagnosis of common medical complications; peripartum cardiomyopathy; fear of childbirth; and pregnancy loss as a risk factor for psychopathology. Epidemiologic information will be presented, as will relevant psychosocial factors related to each phenomenon. Healthcare providers should be sensitive to the distress and anxiety experienced by many women and their families as a consequence of these adverse events and the stressful challenge of any consequential decision-making, as well as stressors in their broader life context that can further exacerbate their distress, and make mental health referrals as appropriate.     

Does comorbid attention-deficit/hyperactivity disorder impact the clinical expression of pediatric obsessive-compulsive disorder?

What is the impact of attention-deficit/hyperactivity disorder (ADHD) on the phenotypic expression of pediatric obsessive-compulsive disorder (OCD). We examined phenotypic features, and functional and clinical correlates in youths with OCD, with and without comorbid ADHD, from a large sample of consecutively referred pediatric psychiatry patients. Although comorbid ADHD had no meaningful impact on the phenotypic expression or clinical correlates of OCD, it was associated with higher rates of compromised educational functioning compared with other OCD youths. Our findings suggest that the OCD phenotype runs true and is not impacted by comorbid ADHD in youths diagnosed with both OCD and ADHD. In such affected youths, both disorders contribute to morbid dysfunction and require treatment. More work is needed to determine whether OCD plus ADHD represents a developmentally and etiologically distinct form of the OCD syndrome.     

ALTERING SHOPPERS' SUPERMARKET PURCHASES TO FIT NUTRITIONAL GUIDELINES: AN INTERACTIVE INFORMATION SYSTEM

This study reports the results of one effort to help supermarket shoppers alter food purchases to make purchases (and meals) that are lower in fat and higher in fiber. A prototype interactive information system using instructional video programs, feedback on purchases with specific goals for change, weekly programs, and the ability to track user interactions and intended purchases was evaluated. The major dependent measure was users' actual food purchases as derived from participants' highly detailed supermarket receipts. After a 5- to 7-week baseline phase, participants were randomly assigned to an experimental or control condition for the 7- to 8-week intervention phase. A follow-up phase began 5 to 8 weeks after participants completed the intervention and discontinued use of the system. The results indicated that experimental participants, when compared to control participants, decreased high fat purchases and increased high fiber purchases during intervention, with evidence for some maintenance of effect in follow-up. Plans for increasing the use and impact of the system are discussed.
