Equality of whom? a genetic perspective on equality (of opportunity)

Rawls’ principle of fair equality of opportunity has been regularly discussed and criticized for being inadequate regarding natural inequalities. In so far as this egalitarian goal is sound, the purpose of the paper is to see how the prospect of radical genetic intervention might affect this particular inadequacy. I propose that, in a post-genetic setting, an appropriate response would be to extend the same rules regulating societal inequalities to a regulation of comparable genetic inequalities. I defend this stance against recent arguments from the authors of From Chance to Choice and from Colin Farrelly’s alternative of the genetic difference principle. Thanks and appreciation to Dr. Pete Morris, Noreen McGuire and Ann Feeney for their support and encouragement. My thanks also to the participants of the Ninth Manchester Graduate (Brave New World 2005) Conference in Political Theory, where a shorter version of this paper was read.     

Assessing the Robustness of Mixture Models to Measurement Noninvariance

Abstract

Recent work reframes direct effects of covariates on items in mixture models as differential item functioning (DIF) and shows that, when present in the data but omitted from the fitted latent class model, DIF can lead to overextraction of classes. However, less is known about the effects of DIF on model performance—including parameter bias, classification accuracy, and distortion of class-specific response profiles—once the correct number of classes is chosen. First, we replicate and extend prior findings relating DIF to class enumeration using a comprehensive simulation study. In a second simulation study using the same parameters, we show that, while the performance of LCA is robust to the misspecification of DIF effects, it is degraded when DIF is omitted entirely. Moreover, the robustness of LCA to omitted DIF differs widely based on the degree of class separation. Finally, simulation results are contextualized by an empirical example.

Changing unbalanced coping profiles-A prospective controlled intervention trial in worksite health promotion

Abstract

Effective coping is based upon a broad variety of available strategies and a good balance between instrumental and palliative coping efforts. Thus, stress management training (SMT) should focus on broadening and balancing individual coping-profiles. This study investigated changes in coping profiles after participation in SMT at the worksite. The sample consisted of 82 healthy working persons who participated in a 12-week-SMT and 55 matched controls without intervention. The SMT consisted of six training elements: three of them (assertiveness, cognitive restructuring and time management) addressed instrumental coping and the other three (relaxation, physical activity and scheduling of pleasant activities) focussed on palliative coping. All subjects filled in standardized questionaires on coping, well-being and strain before and after the training. Cluster analyses performed on initial coping scores resulted in a 3-cluster solution: (1) “active flexible coping” (n = 53), (2) “problem-focused coping” (n = 40) and (3) “resignative avoidant coping” (n = 44). Analyses of covariance revealed that SMT-participants of Cluster 2 showed significant improvements regarding emotion-focused coping and those of Cluster 3 regarding problem-focused coping compared to controls of the same cluster. There were also significant associations between these clusterspecific changes of coping and improvements of well-being. In consequence, the SMT improved coping by supplementing one-sided initial coping-profiles.     

Patient role orientations,doctor-patient fit,and visit satisfaction

Abstract

Two studies were conducted using the Patient-Practitioner Orientation Scale (PPOS), an instrument that measures the role orientations of patients. In the first, 297 students responded to a pool of 61 items concerning their attitudes about doctor-patient relationships (e.g., about power-sharing and the importance of physicians' supportiveness). The scale was reduced, and associations between PPOS scores and gender, race, country of origin as well as Health Locus of Control were found. In Study 2, 90 additional students filled out the PPOS, read two doctor-patient scenarios, and rated their satisfaction as if they had been the patient. In one, the physician exhibited a controlling style, and in the other a more open style. As predicted, patient-centered physicians generated higher satisfaction, and patients were most satisfied with a physician whose style matched their own role orientation. These studies suggest the potential usefulness of the PPOS as an indicator of patient attitudes and doctor-patient fit, and as an predictor of visit satisfaction.     

Making snacking less sinful: (Counter-)moralising obesity in the public discourse differentially affects food choices of individuals with high and low perceived body mass

Objective: As public discourse surrounding obesity highlights the societal costs of obesity and individual’s own responsibility for their weight, being overweight is often framed as immoral. Such ‘moralizing’ messages about being overweight may be a psychological threat for those with high body mass. Attempting to counter-moralise the public discourse (i.e. actively arguing that there is nothing ‘immoral’ about being overweight) may relieve this threat, inducing people, especially those with higher (perceived) weight, to engage in healthier behaviours.

Method: Two experiments were performed among Dutch and US participants. (Counter-)moralisation was manipulated. Body mass and weight-related self-perceptions were measured. The dependent variable was healthy vs. unhealthy snack choice.

Results: (Counter-)moralisation and (perceived) overweight jointly predicted snack choice: counter-moralising messages induced healthy snacking, but only among those who regarded themselves to have a high body mass.

Conclusions: The effects of moralising vs. counter-moralising obesity depended on one’s (perceived) overweight. This suggests that, for people with relatively high weight, the current moralising public discourse on obesity works in counterproductive ways. Campaigns that ‘counter-moralize’ obesity (i.e. that refute moralising messages) are more productive, although they should be tailored to those who see themselves as being overweight.     

Rumination is independently associated with poor psychological health: Comparing emotion regulation strategies

Objective: Emotion regulation (ER) strategies are related to psychological health, with most work examining reappraisal and suppression. Yet, emerging findings suggest that rumination may have stronger relationships with psychological health, namely depression, than other ER strategies. This paper replicated and extended this work by testing whether rumination was independently associated with a range of poor psychological health risk indicators and outcomes. In addition, it explored whether the reason why rumination is so deleterious to health is because it underlies the stress–health relationship.

Design: Participants (n = 218) completed measures online.

Main outcome measures: Surveys assessed ER strategies (reappraisal, suppression, proactive coping, emotion support seeking, and rumination), health risk indicators (hostility, optimism, self-esteem), health outcomes (depression, poor sleep quality, anxiety) and perceived chronic stress.

Results: Multivariate regression analyses revealed rumination as the only ER strategy with a consistent independent effect on all the health risk indicators and outcomes. Bootstrapping analyses revealed indirect effects of perceived chronic stress on all the health variables via rumination.

Conclusion: Rumination had a deleterious relationship with psychological health, perhaps because rumination underlies the relationship between stress and psychological health. Results have implications for interventions, particularly emphasizing the need to target ruminative thinking after stressful experiences.     

The effect of rebranding generic medicines on drug efficacy and side effects

Objectives: Subjective age is an important correlate of health, well-being, and longevity. So far, little is known about short-term variability in subjective age and the circumstances under which individuals feel younger/older in daily life. This study examined whether (a) older adults’ felt age fluctuates on a day-to-day basis, (b) daily changes in health, stressors, and affect explain fluctuations in felt age, and (c) the daily associations between felt age and health, stressors, or affect are time-ordered.

Method: Using an eight-day daily diary approach, N = 43 adults (60–96 years, M = 74.65, SD = 8.19) filled out daily questionnaires assessing subjective age, health, daily stressors, and affect. Data were analysed using multilevel modelling.

Main outcome measures: Subjective age, health, daily stressors, affect.

Results: Intra-individual variability in felt age was not explained by time but by short-term variability in other variables. Specifically, on days when participants experienced more than average health problems, stress, or negative affect they felt older than on days with average health, stress, or negative affect. No time-ordered effects were found.

Conclusion: Bad health, many stressors, and negative affective experiences constitute circumstances under which older adults feel older than they typically do. Thus, daily measures of subjective age could be markers of health and well-being.     

Predicting adolescent health complaints by personality and Behaviors

Abstract

In a sample of 97 male adolescents, individual differences in health complaints were predicted by personality traits and by self-reported health/risk behaviors. Anxiety and loneliness were measured at Times 1 and 2, and health locus of control, various behaviors and health complaints were assessed at the end of the two-year study. A causal model was specified, employing anxiety and loneliness as distal predictors, health locus of control and behaviors as proximal predictors of health complaints. It turned out that anxiety was the most powerful single predictor, and that loneliness exerted a direct effect on health locus of control and behaviors and an indirect effect on health complaints. Risk behavior as well as health behavior were related to complaints. Social integration facilitated not only health behavior but also risk behavior.     

The body sensation hypothesis: A new contribution to the understanding of preventive health behavior

Abstract

A conceptualization of preventive health behaviors (PHBs) is outlined which focuses upon the body sensations that accompany performance of PHB. While many workers have noted that the sensory consequences associated with PHB may be important in understanding why non-symptomatic, healthy individuals engage in PHB, current models of PHB ignore this dimension of health behavior. The Body Sensation Hypothesis suggests that an important function of PHB may be to regulate body sensations by eliminating and avoiding aversive sensations and to produce pleasurable sensations. The implications of the Body Sensations Hypothesis for the definition of PHB, the acquisition of PHB, health education and health-cognitions, and sex differences in PHB are discussed.
