According to the Cognitive reserve hypothesis, several factors related to mental engagement, such as level of education, type of occupation, leisure activities and social network, appear to affect the risk of developing clinical dementia. The present article provides an overview of the studies that have investigated the effects of mental engagement and cognitive stimulation specifically on dementia of the Alzheimer’s type (AD). Mental training and cognitive stimulation interventions in AD have been shown to be useful in increasing patients’ ability in performing activities of daily living (ADL), allowing them to maintain relative independence. Since cognitive engagement and stimulation are known to modify the brain processes to perform tasks, by recruiting alternative and more efficient networks, this review is especially focused on cognitive rehabilitation in AD patients, which has been shown to improve their global functioning and cognition. This perspective stresses the idea that cognitive reserve is not a fixed factor, but can be continuously modified by life experiences, even when the brain is already affected by neuropathology.     

Application of a modified health belief model to hiv preventive behavioral intentions among gay and bisexual men

Abstract

The utility of a modified health belief model (Janz and Becker, 1984) for predicting the intention to use condoms was tested in a study among gay and bisexual men. The model explained a reasonable amount of variance. It was found that younger men's decision to have safe sex was guided by factors other than those that influenced older men. Among younger men, the intention to use a condom was positively related to the relative number of persons with AIDS in their social environment (cues to action) and to the perceived benefits of HIV preventive behavior. Among older men, this behavioral intention was much more determined by their perception of the prevalence of HIV and by their perception of their vulnerability to HIV infection. These findings are important because they may partly explain the recent increase in AIDS-risk behavior among young gay and bisexual men. The discussion focuses on these findings and on the implications for interventions aimed at promoting safe sex.     

Key questions regarding work engagement

This article discusses the concept of work engagement and summarizes research on its most important antecedents. The authors formulate 10 key questions and shape a research agenda for engagement. In addition to the conceptual development and measurement of enduring work engagement, the authors discuss the importance of state work engagement. Further, they argue that the social context is crucial and may set the stage for a climate for engagement with an important role for management. Engaged employees conserve their own engagement through a process of job crafting. After discussing possible dark sides of engagement and the relationship between engagement and health, the article closes with a discussion of organizational interventions to increase work engagement.     

Standard profile for the evaluation of working women's vulnerability to sexual harassment

The aim of the present study was to investigate relationships between Effort-Reward Imbalance (ERI) and employee adverse health (i.e., psychosomatic complaints, physical symptoms, and exhaustion). The Effort-Reward Imbalance Model was extended by discriminating three specific rewards separately (i.e., salary, esteem, and job security). A sample of 167 health-care workers was used to test the relationship between ERI (i.e., high effort accompanied with low reward) and employee adverse health with multiple univariate logistic regression analyses. Separate analyses were carried out with a composite reward scale and with each of the three specific reward scales as independent variables. The results indicate that the health outcomes of ERI vary depending on the specific reward that was used. Generally, the most adverse health effects were found for employees who reported both high efforts and low rewards, thus supporting the ERI Model. Moreover, the strongest effects of ERI on employee health were found when esteem was used as a reward indicator. Job security also appeared to be an important reward in this respect, whereas salary did not have strong effects as a result of ERI. Although the ERI Model was merely supported by the results, current findings also indicate it is important to separate different kinds of rewards, especially in health-care work in order to capture the complexity of working with clients as well.     

Switching on and off … : Does smartphone use obstruct the possibility to engage in recovery activities?

This study examines the impact of work-related smartphone use on daily recovery from work-related efforts. The literature shows that work–home interference (WHI) is an important inhibitor of the recovery process. We propose that the extensive use of smartphones with its implicit request of 24/7 availability inhibits the process of engaging in activities that are required for daily recovery. A total of 80 employees (40 smartphone users, 40 controls) completed a 6-day diary questionnaire over a time period of 2 weeks. Contrary to our hypothesis, smartphone users did not experience more overall WHI than nonusers. Furthermore, four activities aimed at recovery were examined. We predicted that daily WHI would increase employees’ engagement in recovery activities, but only if they did not use a smartphone. Results showed that, for the control group, WHI was positively related to psychological detachment, relaxation, mastery, and control activities, whereas smartphone users facing high WHI did not succeed in engaging in these recovery activities. This implies that being connected to work in the evening hours through smartphones has consequences for the extent to which employees succeed in undertaking recovery activities.     

Towards a multilevel approach of employee well-being

In this commentary, I respond to Ilies, Aw & Pluut’s (Intraindividual models of employee well-being: What have we learned and where do we go from here?, European Journal of Work and Organizational Psychology, in press) call for a theory that distinguishes between traits and states of employee well-being. I use Job Demands–Resources theory to illustrate how we may integrate within- and between-person approaches and findings to design an overall multilevel model of employee well-being. My perspective builds on Ilies et al. and recent findings of research combining relatively stable “traits” with fluctuating states of employee well-being. My goals with this commentary are three-fold: (1) give more insight into possible differences between variables at different levels of analysis; (2) use research to show how trait and state levels of (predictors of) employee well-being may interact; (3) propose a multilevel model that may stimulate future research on the topic.     

The state version of the recovery experience questionnaire: A multilevel confirmatory factor analysis

Although many studies in the field of recovery from work utilize a quantitative diary design, little is known about the validity of the daily measures used in such studies. The present study analyses the factor structure of the state version of the Recovery Experience Questionnaire (REQ) on the between-person (trait) and within-person (state) levels. A total of 127 employees participated in the study. Most of them filled out the questionnaire on three consecutive workdays (N = 375 observations). Results of multilevel confirmatory factor analyses (MCFA) showed that a four-factor model fit the data better than alternative models at both levels of analysis (between and within). In addition, some factor loadings of the four recovery experience dimensions (particularly for relaxation and control) were lower on the day level as compared to the general level. Nevertheless, we conclude that both state and trait versions of the REQ show good psychometric properties. Implications for future research on recovery are discussed.     

The early development of human mirror mechanisms: evidence from electromyographic recordings at 3 and 6 months

In primates and adult humans direct understanding of others' action is provided by mirror mechanisms matching action observation and action execution (e.g. Casile, Caggiano & Ferrari, 2011). Despite the growing body of evidence detailing the existence of these mechanisms in the adult human brain, their origins and early development are largely unknown. In this study, for the first time, electromyographic (EMG) measures were used to shed light on the emergence of mirror motor mechanisms in infancy. EMG activity was recorded while 6‐ and 3‐month‐old infants watched two videos displaying an agent reaching for, grasping and bringing an object either to the mouth or to the head. Results indicate that the motor system of 6‐month‐olds, but not 3‐month‐olds, was recruited and selectively modulated during observation of the goal‐directed actions, favoring the idea that mirror mechanisms driving action understanding gradually emerge during early development.     

Daily Activities and Happiness in Later Life: The Role of Work Status

The aim of this study was to examine the role of work status (i.e. working versus not working) in the relationship between time-use and momentary happiness. We employed a longitudinal research design using monthly assessments via the day reconstruction method over 3 years among 579 older adults. In total, participants reported 84,247 daily activities and accompanying momentary happiness levels. Hierarchical linear modeling results revealed that working older individuals are not happier than nonworking individuals in the overall. However, involvement in work as a daily activity does coincide with higher levels of momentary happiness. Furthermore, working older individuals experience more happiness during relaxing activities, and during weekends, whereas nonworking older individuals experience more happiness during administrative activities. These findings provide novel information on intraindividual differences in lifestyle relating to the everyday happiness between working and nonworking older people which cannot be accurately captured by global survey methods.
