The Perceived Stress Reactivity Scale: measurement invariance, stability, and validity in three countries

There is accumulating evidence that individual differences in stress reactivity contribute to the risk for stress-related disease. However, the assessment of stress reactivity remains challenging, and there is a relative lack of questionnaires reliably assessing this construct. We here present the Perceived Stress Reactivity Scale (PSRS), a 23-item questionnaire with 5 subscales and 1 overall scale, based on an existing German-language instrument. Perceived stress reactivity and related constructs were assessed in N = 2,040 participants from the United Kingdom, the United States, and Germany. The 5-factor structure of the PSRS was found to be similar in the 3 countries. In the U.S. sample the questionnaire was applied using 2 modes of administration (paper-pencil and computerized), and measures were repeated after 4 weeks. Measurement invariance analyses demonstrated full invariance across mode of administration and partial invariance across gender and countries. Scale scores differed between countries and genders, with women scoring higher on most scales. Overall, reliability analysis suggested good stability of PSRS scores over a 4-week period, and validation analysis showed expected associations with related constructs such as self-efficacy, neuroticism, chronic stress, and perceived stress. Perceived stress reactivity was also associated with depressive symptoms and sleep. These associations were particularly strong when individuals scoring high on perceived stress reactivity were exposed to chronic stress. In sum, our findings suggest that the PSRS is a useful and easy-to-administer instrument to assess perceived stress reactivity.     

The Moral Problem of Risk Impositions: A Survey of the Literature

This paper surveys the current philosophical discussion of the ethics of risk imposition, placing it in the context of relevant work in psychology, economics and social theory. The central philosophical problem starts from the observation that it is not practically possible to assign people individual rights not to be exposed to risk, as virtually all activity imposes some risk on others. This is the ‘problem of paralysis’. However, the obvious alternative theory that exposure to risk is justified when its total benefits exceed its total costs faces the standard distributional challenges of consequentialism. Forms of contractualism have been proposed as a solution, but how exactly such theories can be formulated remains problematic, especially when confronted with the difficult cases of mass, novel, risk such as climate change.     

Exploring the career construction interview for vocational personality assessment

This mixed-methods study explored the validity and usefulness of the Career Construction Interview (CCI) with college students (n = 83) from a midsize Southern university. Using Pearson's r correlations, comparisons were made between the three-letter RIASEC Strong Interest Inventory (SII) theme code and RIASEC theme codes derived from coding the CCI narratives of the participants. Results indicated moderate correlation between the CCI and SII participant results.     

Commentary on Paper by Danielle Knafo

The author discusses the importance of Knafo's rich paper on the often neglected subject of solitude but argues for a clearer demarcation of the multifarious states of aloneness, solitude, loneliness, and isolation. While solitude constitutes a state of plentitude, demonstrating an ability to be alone in the company of an Other, loneliness, in contrast, conjures up a sense of dread and despair, foreseeing no link to an Other. Hence, an artwork can fulfill radically different aspects of the various states of aloneness, it can be a product emerging out of a full sense of solitude, or it can function as a forceful shield against the unbearable sense of loneliness.     

On the significance of Hannah Arendt's the human condition for sociology

Arendt's book is an analysis of the vita activa, which comprises the three human activities of labor, work, and action. Her presentation involves a critique of modern and current conceptions of them and of many other social phenomena, and an emphasis on distinctions customarily neglected. The interpretation of her book, disregarding the many factual statements it contains, proceeds in a theoretical vein, analyzing her major conceptions, and then turns practical, asking what we as social scientists who listen to her must do (focusing on “behavior” and “action”, “values”, the means‐end scheme, and man's historicity and dualism). The paper concludes with a brief explication of areas of research seen to emerge out of Arendt's work.     

In focus. Has patient autonomy gone to far? Geneticists' views in 36 nations

We surveyed genetics professionals, patients, and the public about rights to information, to requested services, and to parenthood, posing difficult cases found in practice. In all, 2906 genetics professionals (63%), 499 primary care physicians (59%), 476 North American genetics patients (67%), 394 French patients (51%), 593 German patients (65%), and 988 members of the American public (99%) returned anonymous questionnaires. Results suggest a trend toward increased respect for patient autonomy since an earlier survey in 1985; in most nations more would perform prenatal diagnosis for a couple with 4 daughters who desire a son. A minority (35% in U.S., 14% elsewhere) would perform PND for a deaf couple who want a deaf child, but most (94% in U.S., 62% elsewhere) would do prenatal paternity testing in the absence of rape or incest. About half (51%) would support a woman with fragile X who wants children. The trend to respect patient autonomy was greatest in the U.S. and was least evident in China and India. In general, responses to these cases illustrate a shift away from population or eugenic concerns to a model of genetics focused on the individual.     

Drawing Memories: Edouard Manet's Remembrances of the Past

The author examines Edouard Manet's quotations of traditional masters in his work. Instead of debating whether Manet simply imitated, competed with, or paid tribute to the great painters of the past, the author suggests that Manet used the depictions of his painterly past not as a remedial but as a deliberate device. By relying primarily on Freud's Interpretation of Dreams and Jokes and Their Relation to the Unconscious, the author interprets the traditional works embedded in Manet's paintings as dream thoughts lying behind a façade. The author examines these depictions as if they were associations and memories of Manet's painterly past and in so doing uncovers Manet's subtle use of the past as a means of articulating social commentaries and of creating dialogues with both his contemporaries as well as his predecessors. Drawing on Freud's idea of deferred action (Nachtraegklichkeit), the author illustrates how Manet reflects upon the present through images of the past while at the same time rearticulating the scenes of the past through the lens of the present.     

Cortical plasticity associated with stuttering therapy

Neuroimaging studies have indicated that persistent developmental stuttering (PDS) may be associated both with an abnormality in white matter of left-hemispheric speech areas and a right-hemispheric hyperactivity. The latter may compensate for the deficient structural connectivity in the left hemisphere. To investigate the effects of stuttering therapy on brain activity nine male adults with PDS underwent functional magnetic resonance imaging (fMRI) before and within 12 weeks after fluency shaping therapy. Brain response differences during overt sentence reading before and after therapy were assessed by utilizing random effects analyses. After therapy, a more widespread activation was observed in frontal speech and language regions and temporal areas of both hemispheres, particularly and more pronounced on the left side. Interestingly, distinct posttreatment left-sided activation increases were located directly adjacent to a recently detected area of white matter anomaly [M. Sommer, M.A. Koch, W. Paulus, C. Weiller, C. Buchel (2002). Disconnection of speech-relevant brain areas in persistent developmental stuttering. The Lancet, 360, 380-383] suggesting that fluency shaping techniques reorganize neuronal communication between left-sided speech motor planning, motor execution, and temporal areas. Hence, a therapeutic mechanism can be assumed to remodel brain circuitry close to the source of the dysfunction instead of reinforcing compensation via homologous contralateral brain networks. EDUCATIONAL OBJECTIVES: The reader will learn about and be able to: (1) describe brain activation changes detected shortly after fluency-shaping therapy; (2) identify left-hemispheric regions where a (re)functionalization after fluency-shaping therapy seems to occur adjacent to a recently described abnormal white matter region in PDS subjects; and (3) discuss how an effective cerebral compensation mechanism for stuttering could work.     

Delay-dependent working memory impairment in young-adult and aged 5-HT1BKO mice as assessed in a radial-arm water maze

Serotonin (5-HT) plays a modulatory role in mnemonic functions, especially by interacting with the cholinergic system. The 5-HT1B receptor is a key target of this interaction. The 5-HT1B receptor knockout mice were found previously to exhibit a facilitation in hippocampal-dependent spatial reference memory learning. In the present study, we submitted mice to a delayed spatial working memory task, allowing the introduction of various delays between an exposure trial and a test trial. The 5-HT1BKO and wild-type mice learned the task in a radial-arm water maze (returning to the most recent presented arm containing the escape platform), and exhibited a high level of performance at delays of 0 and 5 min. However, at the delay of 60 min, only 5-HT1BKO mice exhibited an impairment. At a delay of 90 min, all mice were impaired. Treatment by scopolamine (0.8 mg/kg) induced the same pattern of performance in wild type as did the mutation for short (5 min, no impairment) and long (60 min, impairment) delays. The 22-month-old wild-type and knockout mice exhibited an impairment at short delays (5 and 15 min). The effect of the mutation affected both young-adult and aged mice at delays of 15, 30, and 60 min. Neurobiological data show that stimulation of the 5-HT1B receptor inhibits the release of acetylcholine in the hippocampus, but stimulates this in the frontal cortex. This dual function might, at least in part, explain the opposite effect of the mutation on reference memory (facilitation) and delay-dependent working memory (impairment). These results support the idea that cholinergic-serotonergic interactions play an important role in memory processes.
