This study was undertaken to verify the effects of chronic stress and lithium treatments on the hippocampal Na+,K(+)-ATPase activity of rats, as well as to investigate the effects of stress interruption and post-stress lithium treatment on this enzyme activity and on spatial memory. Two experiments were carried out; in the first experiment, adult male Wistar rats were divided into two groups: control and submitted to a chronic variate stress paradigm, and subdivided into treated or not with LiCl. After 40 days of treatment, rats were killed, and Na+,K(+)-ATPase activity was determined. In the second experiment, rats were stressed during 40 days, and their performance was evaluated in the Water Maze task. The stressed group was then subdivided into four groups, with continued or interrupted stress treatment and treated or not with lithium for 30 additional days. After a second evaluation of performance in the Water Maze, rats were killed and Na+,K(+)-ATPase activity was also measured. Results showed an impairment in Na+,K(+)-ATPase activity and in Water Maze performance of chronically stressed rats, which were prevented by lithium treatment and reversed by lithium treatment and by stress interruption. These results suggest that the modulation of Na+,K(+)-ATPase activity may be one of the mechanisms of action of lithium in the treatment of mood disorders. 相似文献

In the infant mental health field, scant conceptual attention has been given to coparenting and family adaptations of non-white family systems, with no evidence-based, community-informed coparenting interventions responsive to unmarried Black mothers’ and fathers’ life circumstances. This study examined 1-year post-partum child and family outcomes of a novel, modest dosage (six sessions) prenatal focused coparenting consultation (FCC) using randomized controlled trial methodology. One-hundred-thirty-eight expectant families (one or both parents identified as Black/African American) were randomized to an intervention (N = 70) or treatment-as-usual (TAU; control) condition (N = 68). TAU families received navigational support in accessing existing community services for pregnant families. Intervention families received TAU plus 6 dyadic FCC sessions led by a Black male-female Community Mentor team. When infants were three and 12 months old, parents reported on coparenting, father engagement, interparental aggression, depressive symptoms, and infant social and emotional adjustment. Intent-to-treat analyses focusing on 12-month post-partum data indicated significant intervention effects on coparenting, interparental psychological aggression, and infants’ emotional adjustment. Improvement was also seen in depression and father engagement, with gains for both groups. Results suggest FCC delivered by same-race Community Mentors to unmarried Black coparents transitioning to parenthood supports infant and family adaptation during the first year of life. 相似文献

OBJECTIVE: This study applied the Common-Sense Model (CSM) to predict risk perception and disease-related worry in 174 individuals with a genetic predisposition to venous thrombosis (thrombophilia). DESIGN: Participants completed an adapted version of the Illness Perception Questionnaire-Revised (IPQ-R) and measures assessing risk perception and worry. RESULTS: Regression analyses revealed that illness perceptions were predictors of risk perception and thrombosis worry. The hypothesis that illness perceptions mediate the relationship between a person's experience of venous thrombosis and perceived risk and thrombosis worry could not be confirmed. CONCLUSIONS: Further research should refine the IPQ-R for populations at risk of a disease and examine the value of the CSM in explaining the relationship between risk perception, worry, and health behavior. 相似文献

IntroductionChronic pain is difficult to treat and often precedes or exacerbates sleep disturbances such as insomnia. Insomnia, in turn, can amplify the pain experience. Both conditions are associated with inflammatory processes, which may be involved in the bi-directional relationship between pain and sleep. Cognitive behavioral therapy (CBT) for pain and CBT for insomnia are evidence based interventions for, respectively, chronic pain and insomnia. The study objectives were to determine the feasibility of combining CBT for pain and for insomnia and to assess the effects of the combined intervention and the stand alone interventions on pain, sleep, and mood outcomes compared to a control condition.MethodsTwenty-one adults with co-occurring chronic pain and chronic insomnia were randomized to either CBT for pain, CBT for insomnia, combined CBT for pain and insomnia, or a wait-list control condition.ResultsThe combined CBT intervention was feasible to deliver and produced significant improvements in sleep, disability from pain, depression and fatigue compared to the control condition. Overall, the combined intervention appeared to have a strong advantage over CBT for pain on most outcomes, modest advantage over both CBT for insomnia in reducing insomnia severity in chronic pain patients.DiscussionCBT for pain and CBT for insomnia may be combined with good results for patients with co-occurring chronic pain and insomnia. 相似文献

Research and theory on the intervening variables that enable individuals who experience marginalization and oppression to achieve well-being have historically relied on an individual level of analysis. Yet, there is a growing body of literature that highlights the roles that contexts play in facilitating processes that result in wellness among marginalized individuals. This paper proposes a conceptual framework that highlights a specific type of setting, referred to as "counterspaces," which promotes the psychological well-being of individuals who experience oppression. Counterspaces are theorized to enhance well-being by challenging deficit-oriented societal narratives concerning marginalized individuals' identities. The conceptual frame proposed here suggests that "challenging" can occur through at least three processes: (1) narrative identity work, (2) acts of resistance, and (3) direct relational transactions. This paper articulates each of these challenging processes. Additionally, the utility of using the Counterspaces framework for thinking critically about and investigating how settings-and the transactional processes that unfold within them-are associated with the promotion of psychological wellness for various marginalized populations is discussed. 相似文献

Reappraisal and distraction, unlike suppression, are known to decrease the intensity of negative emotion in the short term. Little is known about long-term characteristics associated with emotion regulation strategies, however. In a longitudinal study, we examined the relation between the strategies people reported using to regulate emotions during a stressful situation and their later memory for their emotions. Students in Italy rated the intensity of positive and negative emotions they were experiencing as they prepared for their high school exit exam. They also rated the extent to which they were regulating emotion using reappraisal, distraction, and suppression. Six weeks later, students recalled their pre-exam emotions. The more students reported engaging in reappraisal before the exam, the more they overestimated positive emotion and underestimated negative emotion when recalling their experience. The association between reported reappraisal and memory bias was partially mediated by positive changes over time in students' appraisals of the exam preparation experience. Reports of engaging in distraction and suppression were not associated with memory bias. Because remembered emotion guides future choices, these findings suggest that reappraisal is a highly adaptive strategy for coping with stressful situations, not only in the short run, but also in the long run. 相似文献

This study examines household hurricane evacuation logistics—the activities and associated resources needed to reach a safe location and remain there until it is safe to return—during Hurricanes Katrina and Rita. Evacuation logistics variables include evacuation route information sources, evacuation departure dates, vehicles taken, evacuation routes and destinations, travel distances and times, shelter accommodations, and costs of transportation, food, and lodging. This study confirmed previous findings that evacuees take multiple cars, rely on personal experience and traffic conditions to choose their evacuation routes, and are most likely to choose the homes of friends/relatives as their shelter accommodations. However, this study also produced new data on evacuation distances, durations, and costs—as well as associations with demographic and situational variables that are associated with household evacuation logistics. In addition, this study provides additional data indicating that common assumptions about evacuation route choice are incorrect. More research is needed to understand evacuees’ choices of ultimate destinations and evacuation routes. 相似文献

Emotion over‐regulation in infancy has seldom been the focus of empirical research. This study analysed the specificities of over‐regulation when compared with under‐regulation (maladaptive) and adaptive regulation by testing its association with attachment, dyadic emotional interaction, and temperament. The sample consisted of 52 low‐risk mother–infant dyads. During a home visit, dyadic emotional interaction was assessed in the daily routines and free play of 10‐month‐old infants. The infant's emotion regulation was assessed using the Shape Sorter Task, and a temperament questionnaire was completed by the mother. Attachment was assessed at 12 or 16 months using the Strange Situation. As hypothesized, (i) emotion over‐regulation (versus adaptive regulation) was predicted by a lower quality of dyadic emotional interaction and marginally by avoidant attachment; (ii) over‐regulation (versus under‐regulation) was predicted by avoidant attachment; and (iii) the predictive role of avoidant attachment was substantiated after controlling for another measure of mother–infant interaction. Contrary to expectations, temperament did not distinguish between emotion regulation styles. The link between over‐regulation and lower quality of mother–infant emotional interaction and avoidant attachment was demonstrated. There is empirical support to the claim that it is possible to identify emotion over‐regulation in infancy and that it is a maladaptive style of emotion regulation.

On the basis of the results of a previous research, we will present a new interpretation of some psychophysiological component of spatial experience. The research examined the role of the acoustic activity of a metronome (with different frequencies of 66, 144, 192/min) on a space estimation between two points. The stimulus distances between the points were 30, 60, 90 cm. Increasing the metronomic frequency determines an evident contraction of the estimation of the perceived distances for each of the three different stimulus distances. The results have been interpreted in light of a psychophysiological integrated model. 相似文献
