Few studies have examined the impact of motherhood on successful participation in physical activity (PA) interventions. The current study focused on mothers in the Increasing Motivation for Physical Activity or IMPACT study, which aimed to promote PA in sedentary, low-income, ethnically diverse women (74% Latina). The aim of this study was to determine whether certain maternal variables (e.g., ...

The transactional cognitive vulnerability to stress model Hankin & Abramson (Psychological Bulletin, 127:773-796, 2001) extends the traditional diathesis-stress model by proposing that the relationships among cognitions, depressive symptoms, and stressors are dynamic and bidirectional. In this study three different pathways among these variables were assessed simultaneously: (1) cognitive vulne...

Freshwater ecosystems can be impacted by invasive species. Non-native species can become invasive due to their high tolerance to environmental stressors (e.g., pollution and habitat modifications). Yet, tolerance of native and non-native fish species exposed simultaneously to multiple chemical stressors has not been investigated. To quantify tolerance of native and non-native fish species in th...

Gastric mucosal cell death due to various gastric stressors can cause several types of gastric diseases, such as gastric ulcers. In this study, we examined cell death following the short-term treatment of guinea pig gastric mucosal cells in primary culture with various gastric stressors. The short-term treatment of cells with ethanol, hydrogen peroxide or hydrochloric acid caused, in a dose-dep...

We present a phased approach for evaluating the effects of physical, biological, chemical, and psychosocial stressors that may act in combination. Although a phased concept is common to many risk-based approaches, it has not been explicitly outlined for the assessment of combined effects of multiple stressors. The approach begins with the development of appropriate conceptual models and assessm...

Previous research has clearly shown that work stressors are positively related to counterproductive work behavior (CWB). Most of these studies, however, used cross-sectional designs, which limits insight into the direction of effects. Nevertheless, it has been assumed that work stressors have a causal effect on CWB, but the role of CWB as an antecedent of work stressors has been neglected. The ...

Employee stress is a significant issue in the hospitality industry, and it is costly for employers and employees alike. Although addressing and reducing stress is both a noble goal and is capable of resulting in expense reductions for employers, the nature and quantity of hospitality employee stress is not fully understood. The first aim of this study was to identify common work stressors in a ...

American Indian (AI) communities experience disproportionate exposure to stressors and health inequities including type 2 diabetes. Yet, we know little about the role of psychosocial stressors for AI diabetes-related health outcomes. We investigated associations between a range of stressors and psychological, behavioral, and physical health for AIs with diabetes. This community-based participat...

OBJECTIVES To explore three questions: 1) Do chronic stressors predict physiological dysregulation? 2) Is that relationship moderated by characteristics of the individual and his or her social environment? and 3) Do perceived levels of stress mediate the relationship between stressors and dysregulation? METHODS Data come from a nationally representative, longitudinal study of older Taiwanese ...
