The Witness Credibility Scale: An outcome measure for expert witness research

The judge or jury makes a subjective determination of when an expert is credible. However, no published measure exists for assessment of the credibility of expert witnesses. The current study addressed this gap by developing and cross‐validating the Witness Credibility Scale (WCS). Drawing on the narrative literature, we hypothesized that credibility was a product of four factors: “likeability,” “believability,” “trustworthiness,” and “intelligence.” A 41‐item measure was initially constructed based on successive iterations of ratings by a panel of judges using items from the Osgood Semantic Differential measure and was subsequently administered to 264 undergraduates. A factor analysis of the data yielded a factor structure that consisted of four factors labeled, “knowledge,” “likeability,” “trustworthiness,” and “confidence.” The final version of the WCS used 20 adjectives with four subscales of five items, each subscale reflecting high loadings on the respective factors. The scale was then tested in five additional studies, in which the scale successfully differentiated between groups of videotaped experts testifying in manipulated conditions. The empirical data from these studies permit a foundation for comparing outcome data in future research investigations. Copyright © 2010 John Wiley & Sons, Ltd.     

Sufficiency of care in disasters: ventilation, ventilator triage, and the misconception of guideline-driven treatment

This essay examines the management of ventilatory failure in disaster settings where clinical needs overwhelm available resources. An ethically defensible approach in such settings will adopt a "sufficiency of care" perspective that is: (1) adaptive, (2) resource-driven, and (3) responsive to the values of populations being served. Detailed, generic, antecedently written guidelines for "ventilator triage" or other management issues typically are of limited value, and may even impede ethical disaster response if they result in rescuers' clumsily interpreting events through the lens of the guideline, rather than customizing tactics to the actual context. Especially concerning is the tendency of some expert planners to mistakenly assume that medical treatment of respiratory failure: (1) always requires full-feature mechanical ventilators, (2) will always occur in hospitals, and (3) can be planned in advance without sophisticated public consultation about likely ethical dilemmas.     

Evaluation of Techniques to Promote Generalization with Basic Math Fact Skills

The purpose of the current study was to investigate the effect of three procedures designed to promote the generalization of fluent responding of 12 addition facts to 12 related subtraction facts. The first procedure was completed to determine whether increases in the number of digits correct per minute computed on addition facts would generalize to related subtraction facts. If students were fluent in the targeted addition problems and no generalization was detected, a second procedure was implemented where students completed a conceptual lesson. If no generalization was observed during this phase, a third procedure was implemented where students completed addition problems presented in a cloze format. Results failed to demonstrate generalized fluency gains across any of the procedures. Discussion focuses on future directions of generalization research to further our understanding of the conditions needed for generalization to occur.     

Comparing the Personality Disorder Interview for DSM–IV (PDI–IV) and SCID–II Borderline Personality Disorder Scales: An Item–Response Theory Analysis

One-hundred sixty-nine psychiatric outpatients and 171undergraduate students were assessed with the Personality Disorder Interview–IV (PDI–IV; Widiger, Mangine, Corbitt, Ellis, & Thomas, 1995) and the Structured Clinical Interview for DSM–IV Axis II disorders (SCID–II; First, Gibbon, Spitzer, Williams, & Benjamin, 1997) for borderline personality disorder (BPD). Eighty individuals met PDI–IV BPD criteria, whereas 34 met SCID–II BPD criteria. Dimensional ratings of both measures were highly intercorrelated (rs = .78, .75), and item-level interrater reliability fell in the good to excellent range. An item–response theory analysis was performed to investigate whether properties of the items from each interview could help understand these differences. The limited agreement seemed to be explained by differences in the response options across the two interviews. We found that suicidal behavior was among the most discriminating criteria on both instruments, whereas dissociation and difficulty controlling anger had the 2 lowest alpha parameter values. Finally, those meeting BPD criteria on both interviews had higher levels of anxiety, depression, and more impairments in object relations than those meeting criteria on just the PDI–IV. These findings suggest that the choice of measure has a notable effect on the obtained diagnostic prevalence and the level of BPD severity that is detected.     

Metaphor priming in sentence production: Concrete pictures affect abstract language production

People speak metaphorically about abstract concepts—for instance, a person can be “full of love” or “have a lot of love to give.” Over the past decade, research has begun to focus on how metaphors are processed during language comprehension. Much of this work suggests that understanding a metaphorical expression involves activating brain and body systems involved in perception and motor control. However, no research to date has asked whether the same is true while speakers produce language. We address this gap using a sentence production task. Its results demonstrate that visually activating a concrete source domain can trigger the use of metaphorical language drawn from that same concrete domain, even in sentences that are thematically unrelated to the primes, a metaphorical priming effect. This effect suggests that conceptual metaphors play a part in language production. It also shows that activation in the perceptual system that is not part of an intended message can nevertheless influence sentence formulation.     

Impact of average household income and damage exposure on post‐earthquake distress and functioning: A community study following the February 2011 Christchurch earthquake

Post‐traumatic stress, depression and anxiety symptoms are common outcomes following earthquakes, and may persist for months and years. This study systematically examined the impact of neighbourhood damage exposure and average household income on psychological distress and functioning in 600 residents of Christchurch, New Zealand, 4–6 months after the fatal February, 2011 earthquake. Participants were from highly affected and relatively unaffected suburbs in low, medium and high average household income areas. The assessment battery included the Acute Stress Disorder Scale, the depression module of the Patient Health Questionnaire (PHQ‐9), and the Generalized Anxiety Disorder Scale (GAD‐7), along with single item measures of substance use, earthquake damage and impact, and disruptions in daily life and relationship functioning. Controlling for age, gender and social isolation, participants from low income areas were more likely to meet diagnostic cut‐offs for depression and anxiety, and have more severe anxiety symptoms. Higher probabilities of acute stress, depression and anxiety diagnoses were evident in affected versus unaffected areas, and those in affected areas had more severe acute stress, depression and anxiety symptoms. An interaction between income and earthquake effect was found for depression, with those from the low and medium income affected suburbs more depressed. Those from low income areas were more likely, post‐earthquake, to start psychiatric medication and increase smoking. There was a uniform increase in alcohol use across participants. Those from the low income affected suburb had greater general and relationship disruption post‐quake. Average household income and damage exposure made unique contributions to earthquake‐related distress and dysfunction.     

Child Maltreatment in DSM‐5 and ICD‐11

Child maltreatment is widespread and has a tremendous impact on child victims and their families. Over the past decade, definitions of child maltreatment have been developed that are operationalized, face valid, and can be reliably applied in clinical settings. These definitions have informed the revised Diagnostic and Statistical Manual (American Psychiatric Association, 2013) and are being considered for the International Classification of Disease–11 (World Health Organization). Now that these definitions are available in major diagnostic systems, primary healthcare providers and clinicians who see children and families are poised to help screen for, identify, prevent, and treat child maltreatment. This article reviews the definitions of maltreatment in these diagnostic systems, along with assessment and screening tools, and empirically supported prevention and intervention approaches.     

Sexual Encounters and Manhood Acts: Evangelicals,Latter‐Day Saints,and Religious Masculinities

The experiences of men in traditional religions are complex, at times inconsistent, and not necessarily the direct result of religious teachings. This article draws from two qualitative case studies to examine the ways in which evangelical and Latter‐Day Saint men understand masculinity and their spiritual beliefs in the context of sexual activity. The authors present two masculine practices—acceptance of sexual rejection and sexual indifference—that allow religious men in this study to simultaneously challenge and uphold the system of hegemonic masculinity that their traditions promote. These findings point to the moments when creative, interpretative work helps religious men to reconcile their experiences with religious expectations and to alleviate the tensions they face in their everyday lives. This article offers new insights into how gender and sexuality studies may be integrated into the sociology of religion.
