Objectives. The present study, using the conservation of resources theory as a theoretical framework, aims to establish whether work-related bullying is associated with the development of two different types of work-to-private-life interference, i.e., time based and strain based. The study also aims to test whether these relationships are mediated by resilience. Method. In total, 333 nurses filled out a self-report questionnaire. Data analyses were performed by using structural equation model. Results. Results confirmed the hypothesized model: work-related bullying is associated with both strain-based and time-based work-to-private-life interferences. The bootstrap test indicated the presence of an indirect effect of bullying on both types of work-to-private-life interference via resilience. Originality/Value. The present study contributes to improve the understanding on the mechanisms linking work-related bullying and worker well-being, by providing evidence for the mediating role of resilience between bullying and both time-based and strain-based work–life interferences. Practical implications. The present study suggests that the intervention programs, in order to be effectiveness in sustaining work–life balance among nurses, should take into great account the social climate in the organizational context, e.g., the quality of the social climate with particular reference to the bullying prevention.  相似文献

Depression is prevalent among mothers who participate in home visitation programs. This case study describes In-Home Cognitive Behavioral Therapy (IH-CBT), an empirically based treatment for depressed mothers that is strongly integrated with ongoing home visitation. The use of a Parenting Enhancement for Maternal Depression (PEMD) module was added to address parenting difficulties in a depressed mother. This case describes issues and challenges encountered in delivering treatment in the home with low-income, depressed mothers. Issues involving engagement, adaptation to the setting, responding to the unique needs of low-income mothers, and partnership with concurrent home visiting to optimize outcomes are considered. Long-term follow-up (18 months after the end of treatment) permits examination of sustainability of gains. Implications for treating this high-risk population are discussed.  相似文献

We assessed mothers’ self‐reported gains from a postpartum home‐visiting (HV) project in which home visitors are volunteer mothers from the community. Hypotheses were that gains are positively related to (a) mothers’ felt‐closeness with their home visitor, (b) mothers’ level of sociodemographic risk, and (c) the home visitors’ preproject training in support services for families or children (Professionalism). One hundred sixty‐four clients returned written evaluations of the HV project. Items assessing gains were reduced to two factors: Improved Well‐Being (“Self”) and Improved Infant Care (“Infant”). Repeated measures general linear models, with Gains (Self, Infant) as the repeated measure, and multiple regression analyses evaluated the hypotheses. Across the sample, gains on both factors were moderate, although gain scores were higher regarding Self than for Infant. Results show that (a) Mothers’ felt‐closeness with their volunteer was strongly related to mothers’ gains; (b) high‐risk mothers gained more from the project than did mothers of lower risk, particularly regarding Infant Care; and (c) mothers visited by volunteers who were professionals reported more substantial gains than did mothers visited by volunteers who were not professionals. Findings can help explain variance in mothers’ gains from such projects and could be useful in improving their efficacy.  相似文献

This study compared life story memories of emerging adults and early adolescents to other autobiographical memories. Participants described three scenes of their respective life stories, a high point, low point, and turning point narrative, and described the connections between them in a fourth narrative. Participants also related four autobiographical narratives from corresponding time periods for comparison. Narratives were analysed for two measures of causal coherence, narrative complexity and meaning making, and for thematic coherence. Life story narratives contained more self-related lessons and insights and greater recognition of complexity than non-life-story narratives, but these differences were confined to narratives of turning points and connections between events. Thematic connections between narratives were more abstract and self-related in life story narratives. Emerging adults' narratives, when compared to those of early adolescents, showed more evidence of self-related abstract thinking and recognition of multiple dimensions. Findings indicate consistent ways in which life story memories differ from other autobiographic memories, and show evidence of development in adolescence.  相似文献

Developmental transitions are experienced throughout the life course and necessitate adapting to consequential and unpredictable changes that can undermine health. Our six-month study (n = 239) explored whether selective secondary control striving (motivation-focused thinking) protects against the elevated levels of stress and depressive symptoms increasingly common to young adults navigating the challenging school-to-university transition. Path analyses supplemented with tests of moderated mediation revealed that, for young adults who face challenging obstacles to goal attainment, selective secondary control indirectly reduced long-term stress-related physical and depressive symptoms through selective primary control and previously unexamined measures of discrete emotions. Results advance the existing literature by demonstrating that (a) selective secondary control has health benefits for vulnerable young adults and (b) these benefits are largely a consequence of the process variables proposed in Heckhausen et al.’s (2010) theory.  相似文献

Abstract

There is a considerable amount of research concerning (he relationship between psychological variables and the postoperative outcome of surgery. However, little attention has been paid to the potential influence of psychological factors on infra-operative variables, most notably on anaesthetic requirement. The present study investigates the influence of surgery-related trail and slate anxiety as well as of dispositional and surgery-related actual coping on several indicators of intra- and postoperative adjustment. In addition, a possible mediating effect of stress-induced analgesia on the relationships between anxiety, coping, and intraoperative anaesthetic requirements was evaluated. Sixty-one patients undergoing elective lumbar iniclcotomy completed questionnaires regarding anxiety and coping variables one day before surgery. Intraoperative adjustment was assessed by measuring EEG-controlled anaesthetic requirements for induction and maintenance of anaesthesia, β-endorphin plasma concentration was collected preoperatively in the induction room. Postoperative outcome was assessed on the third day after surgery by questionnaires regarding pain experience, physical condition and emotional state. For preoperative anxiety as well as vigilant coping behaviour, there were opposite relationships with subjective measures of adjustment (e.g. self-reported postoperative pain experience), on the one side, and objective measures on the other (e.g., intraoperative anaesthetic requirement). Stress-induced analgesia was found for the subgroup of high-anxious patients. The results indicate that psychological programmes aimed at facilitating patients' perioperative adjustment should consider the different effects of anxiety and coping on subjective and objective measures.  相似文献

Abstract

A model of adolescent health risk behavior that is both cognitive and social-psychological in orientation is described, and an aspect of the model is tested empirically. The model suggests that health risk behaviors (e.g., smoking or drunk driving), especially among adolescents, are not always intended or premeditated, but instead are often reactions to risk-conducive circumstances. Because they are not entirely premeditated, such behaviors are not accurately predicted by “traditional” behavioral intention measures, but are predicted by a central construct in the model labeled behavioral willingness. Results of two studies indicate that both intention (expectation) and willingness measures predict future risk behaviors, and do so independent of one another. Additional analyses provide further evidence of discriminant validity between the two constructs by indicating that they relate differently to perceptions of personal vulnerability to the health risks associated with these behaviors.  相似文献
