Contributions of empirical research to medical ethics

Empirical research pertaining to cardiopulmonary resuscitation (CPR), clinician behaviors related to do-not-resuscitate (DNR) orders and substituted judgment suggests potential contributions to medical ethics. Research quantifying the likelihood of surviving CPR points to the need for further philosophical analysis of the limitations of the patient autonomy in decision making, the nature and definition of medical futility, and the relationship between futility and professional standards. Research on DNR orders has identified barriers to the goal of patient involvement in these life and death discussions. The initial data on surrogate decision making also points to the need for a reexamination of the moral basis for substituted judgment, the moral authority of proxy decision making and the second-order status of the best interests standard. These examples of empirical research suggest that an interplay between empirical research, ethical analysis and policy development may represent a new form of interdisciplinary scholarship to improve clinical medicine.     

Ethnicity,Life Satisfaction,Stress, Familiarity,and Stigma Toward Mental Health Treatment

The authors examined the relative contribution of ethnicity, life satisfaction, level of stress, familiarity with mental health treatment, and self- and public stigma on attitudes toward mental health treatment among a diverse sample (N = 632) of adults. Results indicated that ethnicity, stress, familiarity, and self-stigma of mental illness were significant predictors of attitudes. Additionally, familiarity with mental health treatment moderated the relationship between public stigma and attitude.     

The cognitive load of physical activity in individuals with high and low tolerance to effort: An ecological paradigm to contrast stepping on the spot and stepping through space

Performing a physical activity means dealing with the challenges and difficulties occurring during the task. The more a person possesses the cognitive ability to deal with the complexity of the task, the more that person will be able to face the difficulties in activity regulation. However, no studies have been designed to investigate the cognitive dimension of physical activity. In the present study, we present an original in-task methodology that offers the means to assess the cognitive and physical load of a physical activity. Through the application of a dual task paradigm, we report in-task changes in cognitive abilities and physiological experiences in low and high tolerant individuals during the practice of one of two whole-body stepping tasks. The findings confirmed that stepping through space is a physical activity that requires more cognitive resources and is perceived as more cognitively and physically challenging than stepping on the spot. We demonstrated also that the tolerance to effort, which is a psychological factor, plays a non-negligible role in the way the activity sessions were experienced. The affective states in low tolerant individuals were always more negative than those reported by high tolerant individuals. Our findings argue for the existence of a cognitive dimension to physical activity with tolerance to effort being a moderator of individuals’ affective experience to exercise.

More than just a pretty face and a hot body: multiple cues in mate-choice

Mate preferences have been well studied in social and evolutionary psychology. In two studies (N = 490), using two different measurement techniques, we examined mate preferences for the body and the face in the context of other traits. Results replicated prior research on mate preferences across the sex of the participant and mating duration but clarified the nature of preferences for physical attractiveness. Generally, physical attractiveness was a necessity in short-term mating and for men and traits like kindness were a necessity in long-term mating and for women. Men wanted a short-term mate who had a good body, likely because that body advertises fertility whereas both sexes wanted a mate with a nice face for a long-term mate, which is likely because the face is a cue based on structural properties related to health. Sex and mating-duration differences on preferences for attractive faces and bodies were robust to differences in measurement technique.     

Conceptualizing Sex Offender Denial From a Multifaceted Framework: Investigating the Psychometric Qualities of a New Instrument

The authors examined the psychometric properties of a clinician‐rated measure of sex offender denial. Convergent and discriminant validity for the measure was supported, and given its relationship to treatment attitudes, the measure demonstrated utility for assessing treatment change and readiness.     

Evasive action characteristics of motorcycle riders towards occluded-surprise and expected pedestrians: A pedestrian mock-up study

Evasive action performance of motorcycle riders plays a vital role in the prevention of road crashes. In possible conflicting scenarios, motorcycle riders need to respond quickly and perform evasive actions successfully to prevent collisions with other vulnerable road users such as crossing pedestrians. To study the motorcycle rider behavior in conflicts with occluded and visible pedestrians, we designed four mock-up pedestrian scenarios, which includes, two surprise scenarios, one stationary scenario, and one expected scenario. Riders’ responses to the conflicts were measured using instrumented vehicle’s trajectory. Most riders preferred deceleration over swerving at the beginning of the interaction, followed by swerving at manageable speeds. Further, the analysis of riders’ deceleration rates revealed that a linear relationship existed between the deceleration rates and time to collisions (TTC). The study also analyzed the riders’ responses using repeated-measures analysis of variance (RM-ANOVA) to check for the effect of scenario type on deceleration rates. Results indicated that scenario type significantly affected the mean deceleration rates. Further, RM-ANOVA analysis carried out on the jerk behavior of motorcycle riders indicated that there was a significant effect of scenario type on the jerk behavior. Motorcycle riders’ jerks varied linearly with TTC and motorcyclists employ relatively higher decelerations and jerks when faced with pedestrians emerging suddenly from occluded locations such as from the blind spots formed due to parked vehicles. This study helps in understanding motorcycle rider behavior in critical situations and shows the need for assistive evasive systems for motorcycle riders to mitigate collisions with other vulnerable road users.     

An investigation into the psychometric properties of the CORE‐OM in patients with eating disorders

Aim: The current study aimed to explore the psychometric properties of the CORE‐OM (Clinical Outcomes in Routine Evaluation – Outcome Measure) when used in an eating disorder sample. Method: The CORE‐OM was administered at assessment to 360 individuals referred to an eating disorders service. Principal component analysis was conducted to look at the psychometric structure of the CORE‐OM, and psychometric properties were investigated using analyses of reliability and validity. Results: Analyses of the psychometric structure suggested a three‐component solution reflecting negatively worded, positively worded and risk items. The CORE‐OM showed good acceptability, acceptable internal and test‐retest reliabilities, as well as good convergent and known groups validity. Conclusions: The results of the current study support the CORE‐OM as a reliable and valid measure for assessing psychological distress in eating disorders.     

The Transformative Effects of Stigma: Coping Strategies as Meaning‐Making Efforts for Immigrants Living in Greece

The present article examines the strategies that immigrants living in Greece use to cope with stigma that arises in their interaction with both Greek society and their communities of origin. Drawing on interviews and focus groups conducted with immigrants from a variety of countries, a dialogical analysis illuminates the ways in which immigrants actively negotiate stigmatizing perspectives and transform themselves. Strategies include the deployment of social categories such as those of ‘human being’ and ‘crazy’ person, and concepts such as those of ‘lawfulness’ and ‘fate’. These were used to construct meanings of equality and inclusion into society, to deny responsibility for stigma and to discredit stigma as absurd. They enabled participants to see themselves as proud, equal, self‐dependent individuals who plan actions for social change. The article suggests that coping with stigma should not only be understood in terms of stress regulation, leading to positive or negative outcomes, as suggested by current literature, but as a meaning‐making effort, through which individuals transform the way they see themselves and act within their world. A meaning‐making approach moves away from individualistic, outcome‐oriented explanations to a socially situated perspective on stigma that studies the processes through which social meanings are subjectively perceived as stigmatizing and are used to challenge stigma.

A systematic review of the literature on counselling and psychotherapy for the prevention of suicide: 1. Quantitative outcome and process studies

Scope of review: The paper reports a meta‐review of 15 previous systematic reviews and meta‐analyses of the literature concerning the outcome of counselling and psychotherapy with people at risk of suicide; a meta‐analysis of 67 outcome studies in this area; and a narrative review of 17 studies of the therapeutic process. Publication time span: The literature reviewed was published between 1981 and 2008. Publication origin: The majority of the literature reviewed was by authors from the USA or the UK, but there were also authors from other European countries, Australia, Canada, India, and Sri Lanka. Findings: There is evidence of the effectiveness of dialectical behaviour therapy, cognitive‐behavioural therapy, and problem solving therapy, but also for other forms of therapy. Therapist and client variables, as well as the therapeutic relationship, appear to be related to treatment outcome. Conclusions: People at risk of suicide should have access to psychological interventions, including, but not necessarily limited to, those within the cognitive‐behavioural spectrum. Therapies for which there have been promising findings, but which are under‐researched, should be a research priority.
