Depression and sleep quality in older adults: a meta-analysis

The literature emphasizes depression and poor sleep quality as problems that affect many elderly individuals. However, these problems have been related in few studies and there is no meta-analysis performed so far on this relationship. The present research reviewed the studies performed on the subjective sleep quality in order to understand how it relates to depression in older adults. The review was conducted in January 2016 and comprised publications between 2005 and 2015. Based on the electronic databases Web of Science and EBSCO, we used the keywords ‘sleep quality’, ‘depression’, and ‘older’ to identify the empirical studies performed. After assessing the collected studies, we selected those that presented the elderly as participants, resulting in nine papers (N = 3069). A random-effects method was used to evaluate the relationship between depression and sleep. We found that an older person’s lack of good sleep quality is significantly related with depression. The main limitation of this study was the difficulty in collecting a greater number of studies. Future research should consider the importance of additional variables (e.g. moderators) in order to understand and investigate viable interventions for prevention and health promotion in the elderly.     

THE PARADOX OF BENEFICIAL RETIREMENT

Morally, when should one retire from one's job? The surprising answer may be ‘now’. It is commonly assumed that for a person who has acquired professional training at some personal effort, is employed in a task that society considers useful, and is working hard at it, no moral problem arises about whether that person should continue working. I argue that this may be a mistake: within many professions and pursuits, each one among the majority of those positive, productive, hard working people ought to consider leaving his or her job.     

An Integrated Model for the Study of Teacher Motivation

Des recherches récentes ont montré que les enseignants souffraient plus que d’autres groupes professionnels d’un manque de motivation au travail. Une compréhension globale de la motivation des enseignants exige un modèle adéquat. L’objectif principal de cette recherche était de proposer et de mettre à l’épreuve un modèle de la motivation des enseignants qui intégre des concepts de plusieurs théories cognitivo‐motivationelles. Le modèle intégré s’appuie sur la schéma expectation‐valence et celui de l’incapacité acquise, mais surmonte quelques‐unes de leurs imperfections. L’échantillon était composé de 272 enseignants des écoles élémentaires et secondaires du Portugal. Ils ont répondu à une série d’inventaires destinés à mesurer leurs expectations de contrôle, de succès et d’efficacité, leurs attributions, leur motivation intrinsèque, la valence de leurs buts perçus et comment tout ceci interagit pout agir sur l’engagement professionnel (la variable exogène du modèle). Les analyses des coefficients de pistes et de la variance des variables endogènes valident le modèle intégré proposé ici et suggèrent des stratégies de formation pour accroître la motivation des enseignants. Recent studies show that teachers suffer more than other professional groups from the occupational lack of motivation. A global understanding of teacher motivation requires an adequate framework for its study. The main goal of the current research was to propose and test a model of teacher motivation that integrates constructs from several cognitive‐motivational theories. This integrative model starts from the perspectives of Expectancy‐Value and Learned Helplessness but overcomes some of the limitations of each. The participants were 272 elementary and secondary teachers in Portugal. They responded to a series of inventories designed to measure their expectancies of control, success and efficacy, attributions, intrinsic motivation and perceived goal value levels, and how these interact to influence professional engagement (the model's exogenous variable). Analyses of path coefficients and the variance of endogenous variables support the proposed integrated model and suggest strategies for teacher education that may increase teacher motivation.     

Sick body, vigilant mind: the biological immune system activates the behavioral immune system

Activation of the behavioral immune system has been shown to promote activation of the biological immune system. The current research tested the hypothesis that activation of the biological immune system (as a result of recent illness) promotes activation of the behavioral immune system. Participants who had recently been ill, and had therefore recently experienced activation of their biological immune system, displayed heightened attention to (Study 1) and avoidance of (Study 2) disfigured individuals--cognitive and behavioral processes reflecting activation of the behavioral immune system. These findings shed light on the interactive nature of biological and psychological mechanisms designed to help people overcome the threat of disease.     

Experiences of demand and control during daily life are predictors of carotid atherosclerotic progression among healthy men.

OBJECTIVES: The authors previously reported that individuals who rate their daily life as more demanding or less controllable by momentary electronic diary (ED) reports showed greater intima-medial thickness (IMT) by carotid ultrasonography. They now present prospective findings on this relation. DESIGN: Three hundred thirty-five healthy individuals (ages 50-70 at study onset) completed ongoing ratings of activity and mood over a 6-day period, using ED assessments. MAIN OUTCOME MEASURES: Mean bilateral carotid artery IMT was measured at baseline and 36 months later. RESULTS AND CONCLUSION: Mean ratings of high demand and low control were significantly associated with IMT progression among men but not among women. These associations were not explained by traditional risk factors or by measures of occupational stress. Effects were partially accounted for by elevated ambulatory heart rates among those with low ratings of control. These data support the utility of ED-based measures for examining psychosocial risks in the prediction of cardiovascular disease progression.     

The medium can influence the message: Print-based versus digital reading influences how people process different types of written information

While electronic reading devices are extremely popular, research is equivocal regarding their benefits for outcomes such as reader comprehension. Integrating literatures on reading medium comparisons and matching effects in persuasion, this research tested whether comprehension is maximized when the content of the material (e.g., whether it is traditional vs. modern) matches the medium (e.g., reading from a traditional book vs. digital e-reader). In Study 1, participants read a traditional- or modern-themed short story from either a book or an e-reader. Story comprehension was greater when participants read from the printed medium compared to the e-reader, an effect that was marginally moderated by story content, consistent with a matching effect. In Study 2, participants read a persuasive message that emphasized either a traditional versus modern solution to improving health in either a magazine format or on an iPad. Message comprehension was marginally greater among participants who read their message in a printed format. Participants’ interest in weight loss showed evidence of a matching effect – participants were more interested in losing weight when a modern solution to obesity article was presented on an iPad compared to a printed format. The results are applied to the study of reading and attitude change.
