Racial/ethnic differences moderate associations of coping strategies and posttraumatic stress disorder symptom clusters among women experiencing partner violence: a multigroup path analysis

Background: Past research underscores the key role of coping strategies in the development, maintenance, and exacerbation of posttraumatic stress disorder (PTSD) symptoms. The goal of the current study was to extend existing literature by examining whether race/ethnicity moderates the relations among coping strategies (social support, problem-solving, avoidance) and PTSD symptom clusters (intrusion, avoidance, numbing, arousal).

Methods: Participants were 369 community women (134 African Americans, 131 Latinas, 104 Whites) who reported bidirectional aggression with a current male partner. Multigroup path analysis was utilized to test the moderating role of race/ethnicity in a model linking coping strategies to PTSD symptom clusters.

Results: The strength and direction of relations among coping strategies and PTSD symptom clusters varied as a function of race/ethnicity. Greater social support coping was related to more arousal symptoms for Latinas and Whites. Greater problem-solving coping was related to fewer arousal symptoms for Latinas. Greater avoidance coping was related to more symptoms across many of the PTSD clusters for African Americans, Latinas, and Whites, however, these relations were strongest for African Americans.

Conclusion: Results provide support for the moderating role of race/ethnicity in the relations among coping strategies and PTSD symptom clusters, and highlight potential targets for culturally informed PTSD treatments.     

Headphone screening to facilitate web-based auditory experiments

Psychophysical experiments conducted remotely over the internet permit data collection from large numbers of participants but sacrifice control over sound presentation and therefore are not widely employed in hearing research. To help standardize online sound presentation, we introduce a brief psychophysical test for determining whether online experiment participants are wearing headphones. Listeners judge which of three pure tones is quietest, with one of the tones presented 180° out of phase across the stereo channels. This task is intended to be easy over headphones but difficult over loudspeakers due to phase-cancellation. We validated the test in the lab by testing listeners known to be wearing headphones or listening over loudspeakers. The screening test was effective and efficient, discriminating between the two modes of listening with a small number of trials. When run online, a bimodal distribution of scores was obtained, suggesting that some participants performed the task over loudspeakers despite instructions to use headphones. The ability to detect and screen out these participants mitigates concerns over sound quality for online experiments, a first step toward opening auditory perceptual research to the possibilities afforded by crowdsourcing.     

The Psychosocial Impact of Undergoing Prophylactic Total Gastrectomy (PTG) to Manage the Risk of Hereditary Diffuse Gastric Cancer (HDGC)

Individuals identified as at high risk of developing Hereditary Diffuse Gastric Cancer (HDGC) are advised to undergo prophylactic surgery - have their stomach removed - in their early twenties. Research with (older) cancer patients who undergo gastrectomy for curative reasons suggests that gastric resection has a number of physical and psychosocial sequelae. Because it is difficult to extrapolate the findings of studies of older cancer patients to younger healthy patients who are considering prophylactic total gastrectomy (PTG), the aim of this qualitative interview study was to determine the psychosocial implications of undergoing prophylactic surgery to manage genetic risk. Fourteen men and 13 women from the UK’s Familial Gastric Cancer study who had undergone PTG were invited to participate in qualitative interviews. Most reported that undergoing surgery and convalescence was easier than anticipated. There was evidence that age affected experiences of PTG, with younger patients tending to report faster recovery times and more transient aftereffects. All saw the benefits of risk reduction as outweighing the costs of surgery. Surgery was described as having a range of physical impacts (disrupted appetite, weight loss, fatigue, GI symptoms) that had related psychological, social and economic implications. Those considering PTG need to be aware that its impact on quality of life is difficult to predict and negative sequelae may be ongoing for some individuals.     

The problem of invoking infinite polytheisms: a response to Raphael Lataster and Herman Philipse

Raphael Lataster and Herman Philipse present an argument which they think decisively demonstrates polytheism over monotheism, if theism is assumed. Far from being decisive, the argument depends on very controversial and likely false assumptions about how to treat infinities in probability. Moreover, these problems are well known. Here, we focus on three objections. First, the authors rely on both countable additivity and the Principle of Indifference, which contradict each other. Second, the authors rely on a particular way of dividing up the possibility space, when there are equally as reasonable alternative divisions which give different answers to the one the authors arrived at. Third, the authors’ argument proves too much, giving us an argument against many positions we should not be able to argue against so easily.     

The right hemisphere maintains solution-related activation for yet-to-be-solved problems

In five experiments, we examined the time course of hemispheric differences in solution activation for insight-like problems. We propose that solving insight problems requires retrieval of unusual interpretations of problem elements, and that right-hemisphere (RH) coarse semantic coding is more likely than left-hemisphere (LH) fine semantic coding to maintain semantic activation of such interpretations. In four experiments, participants attempted word problems for 7 sec (Experiments 1A and 1B) or 2 sec (Experiments 2A and 2B), and 750 msec later responded to lateralized target words. After 7 sec of solving effort, Experiment 1A participants showed greater solution-related priming (i.e., they named solutions faster than unrelated words) for left visual field-RH (lvf-RH) targets than for right visual field-LH (rvf-LH) targets, and Experiment 1B participants made faster solution decisions on target words presented to the RH, as previously demonstrated following 15 sec of effort. After 2 sec of solving effort in Experiment 2A, women showed symmetric solution-related priming, although men showed a slight lvf-RH advantage in priming; and in Experiment 2B participants made equally quick solution decisions for targets presented to the LH and to the RH. In Experiment 3, participants viewed the problems for 1,250 msec then named lateralized target words; they showed symmetric solution-related priming. These experiments demonstrate solution activation initially in both hemispheres, but maintained solution activation only in the RH.     

Temporal and spatial distance in situation models

In two experiments, we investigated how readers use information about temporal and spatial distance to focus attention on the more important parts of the situation model that they create during narrative comprehension. Effects of spatial distance were measured by testing the accessibility in memory of objects and rooms located at differing distances from the protagonist's current location. Before the test probe, an intervening episode was inserted in the narrative. Story time distance was manipulated by stating that the intervening episode lasted for either minutes or hours. Discourse time--that is, time spent reading from prime to test--was manipulated by describing the intervening episode either briefly or at length. Clear effects of story time distance and spatial distance on accessibility were found, whereas discourse time distance did not affect accessibility. The results are interpreted as supporting constructionist theories of text comprehension.     

Mass Response to the Lewinsky Scandal: Motivated Reasoning or BayesianUpdating?

This study attempts to account for the vastly different trajectories taken by mass andelite opinion in the wake of the Lewinsky affair. Data from a panel study, collected before andjust after the scandal broke, suggest that Clinton's prior popularity indelibly colored massresponse to the scandal, thereby constraining citizens' reactions. As would be predicted bytheories of "motivated reasoning," the influence of various considerations (like thecredibility and importance of the allegations) on reactions to the scandal was conditional uponprior affect for the president. Such findings are difficult to accommodate within the more rational"Bayesian updating" perspective. These data shed light on mass response to theLewinsky scandal in particular and citizen reaction to presidential behavior more generally, aswell as on the cognitive mechanisms that facilitate motivated reasoning in candidate evaluation.     

Factors associated with outcome of cognitive-behavioural treatment of chronic post-traumatic stress disorder

The study examined factors that were associated with outcome in the treatment of PTSD. A trial of cognitive therapy compared to imaginal exposure of chronic PTSD showed that although clinical improvements were obtained after treatment and at 6 month follow-up one type of treatment was not significantly superior to the other. Characteristics of the patient, the trauma and treatment and of pretreatment clinical measures were investigated as predictors of PTSD outcome. Eleven variables were significantly associated with the pre- to post-treatment change in CAPS severity scores. Of these, three (duration of therapy, gender and suicide risk) were selected into a step-wise multiple regression equation to explain 36.5% of the outcome. Similarly, nine variables were significant associated with the pretreatment to follow-up change with three variables (number of missed therapy sessions, residential status and co-morbid GAD) being selected into the equation and explaining 36.9% of the outcome. The best predictor of outcome was inconsistent attendance at therapy.
