The Contribution of Physical Activity to Health-Related Quality of Life: New Population Estimates from National Survey Data

Sedentary lifestyles have been linked to higher rates of stroke, hypertension, depression, certain types of cancers, and cardiovascular disease, and increased risk of mortality. The link between physical inactivity and health has led to research on how physical activity (PA) interventions might improve health-related quality of life (HRQoL). Estimates of HRQoL improvements are typically focused on targeted at-risk groups, however. Given that almost half of the U.S. adult population is physically inactive, it would be helpful to broaden our understanding of how PA relates to quality of life for the population at large. In this study, we calculated the HRQoL gains attributable to PA across three nationally representative data sets that use different quality of life measures, and assessed the reliability in the results. The data sets used were the Medical Expenditure Panel Survey (MEPS), the Behavioral Risk Factor Surveillance System (BRFSS), and the National Health Interview Survey (NHIS). Quasi-likelihood regression modeling with a beta distribution was used to generate the estimates. We found mean HRQoL scores were very similar across the three data sets and the estimated HRQoLs gained from PA varied only slightly, suggesting that all three provide reliable estimates for the general population.

     

American psychology and the religious imagination

In just three generations, American psychology grew from a fledgling science to a culturally authoritative discipline. Standard accounts of psychology's meteoric rise typically omit what most needs to be illuminated: the resonance between psychological theory and the symbolic universe underlying America's popular religious imagination. This article sketches a cultural history of American psychology by examining how many of its core concepts invoke a metaphysical horizon associated with the nation's heritage of unchurched spirituality.     

Dream recall and the full moon

There is ongoing debate on whether the full moon is associated with sleep and dreaming. The analysis of diaries kept by the participants (N = 196) over 28 to 111 nights showed no association of a full moon and dream recall. Psychological factors might explain why some persons associate a full moon with increased dream recall.     

A closer look at the relationship between justice perceptions and union participation.

In this study, a series of nested models was tested to assess the extent to which the relationship between process-related justice and union participation is mediated by perceived union support and union commitment. Members of a steelworkers' local (N = 615) participated in the study. Fit indices most strongly supported a fully mediated model. Unlike previous research, process-related justice was operationalized as 2 distinct variables: procedural and interactional justice. Interactional justice was found to have a substantially stronger relationship with support perceptions than procedural justice. Results also indicated union support accounted for a greater amount of unique variance in union commitment than perceived union instrumentality. The results are discussed in relation to trust theory and the generalization of organization science across different types of organizations.     

Pursuing Academic Interests: The Role of Implicit Theories

Students can believe that their academic interests are fixed (entity theory) or malleable (incremental theory). A measure of implicit theories of academic interests was developed to examine how such theories influence students' decisions to retain or change their majors. As hypothesized, entity theorists who believed that they were not doing well in their majors were more likely to choose a new major than were all other groups. This result is consistent with previous findings that entity theorists tend to give up in the face of adversity.     

What do Patients Prefer: Informed Consent Models for Genetic Carrier Testing

The recent increased number of conditions for which patients can undergo genetic carrier testing raises the question of how best to obtain pre-test informed consent. Clinical approaches vary from a minimalist model to a model where patients are given detailed information about all conditions to be screened for. Few data exist as to patient preferences, or how information impacts decision-making. Eight high-literacy focus groups were conducted to assess the knowledge and preferences of pregnant patients and their male partners. Most groups indicated that some balance between details and brevity was optimal, recognizing that anxiety can occur when patients are provided with too much information and that the wide range of tests offered during pregnancy often led to confusion. Critical areas for the informed consent process included (1) details about the conditions and risk of being a carrier, (2) logistics of testing, (3) next steps if the test is positive, and (4) prognosis, options and resources if the child were to be affected with a disorder. It will be useful to develop model consent programs and prospectively assess their impact on informed consent and patient satisfaction, both when positive and negative results are received.     

What we know about what we have never heard: evidence from perceptual illusions

Are speakers equipped with preferences concerning grammatical structures that are absent in their language? We examine this question by investigating the sensitivity of English speakers to the sonority of onset clusters. Linguistic research suggests that certain onset clusters are universally preferred (e.g., bd>lb). We demonstrate that such preferences modulate the perception of unattested onsets by English speakers: Monosyllabic auditory nonwords with onsets that are universally dispreferred (e.g., lbif) are more likely to be classified as disyllabic and misperceived as identical to their disyllabic counterparts (e.g., lebif) compared to onsets that are relatively preferred across languages (e.g., bdif). Consequently, dispreferred onsets benefit from priming by their epenthetic counterpart (e.g., lebif-lbif) as much as they benefit from identity priming (e.g., lbif-lbif). A similar pattern of misperception (e.g., lbif-->lebif) was observed among speakers of Russian, where clusters of this type occur. But unlike English speakers, Russian speakers perceived these clusters accurately on most trials, suggesting that the perceptual illusions of English speakers are partly due to their linguistic experience, rather than phonetic confusion alone. Further evidence against a purely phonetic explanation for our results is offered by the capacity of English speakers to perceive such onsets accurately under conditions that encourage precise phonetic encoding. The perceptual illusions of English speakers are also irreducible to several statistical properties of the English lexicon. The systematic misperception of universally dispreferred onsets might reflect their ill-formedness in the grammars of all speakers, irrespective of linguistic experience. Such universal grammatical preferences implicate constraints on language learning.     

Automatic emotion regulation during anger provocation

Individuals frequently have to regulate their emotions, especially negative ones, to function successfully. However, deliberate emotion regulation can have significant costs for the individual. Are there less costly ways to achieve emotion regulatory goals? In two studies, we test the hypothesis that more automatic types of emotion regulation might provide the benefits of deliberate emotion regulation without the costs. Study 1 introduces a priming technique that manipulates automatic emotion regulation. Using this priming technique, we show that relative to priming emotion expression, priming emotion control leads to less anger experience in response to a laboratory anger provocation. Study 2 examines the experiential and physiological consequences of automatic emotion regulation. Results suggest that relative to priming emotion expression, priming emotion control reduces negative emotion experience without maladaptive cardiovascular responding. Together, these findings suggest that automatic emotion regulation may provide an effective means of controlling powerful negative emotions.
