Purpose: to evaluate the relationship between unplanned pregnancy (UP), a common problem in high and low income countries and maternal depression (MD). Methods: Secondary analysis of data from a prospective cohort study with pregnant women recruited from 10 primary care clinics of the public sector in São Paulo, Brazil. Participants were questioned about pregnancy intention at 20–30 weeks of gestation. The Self Report Questionnaire score >7 was used to evaluated the presence of depression during pregnancy and 11 months after childbirth. Four groups of MD were defined: never; antenatal only; postnatal only; persistent (both antenatal/postnatal). Multinomial logistic regression was used to assess the relationship between UP and MD, controlling for confounding. Results: Data were analysed for 701 at the postpartum period. Five hundred and sixty-two (67.8%) women did not plan the pregnancy. Women with UP had 2.5 more risk of being depressed during both assessments (during pregnancy and postpartum) when compared to women with a planned pregnancy (RR: 2.5; 95% CI: 1.47:4.30). In the adjusted models, women with UP were significantly more likely to have persistent depression (RR: 2.3; 95% CI: 1.2:4.3). Conclusion: UP is an independent risk factor for persistent depression, but not for postpartum depression  相似文献

This survey study explored the effects of work-to-family conflict and family-to-work conflict on withdrawal behaviors at work (family interruptions at work, lateness to work, and absenteeism) among both members of 359 dual-earner couples. Using a systems theory framework, regression analyses revealed significant individual-level and crossover effects for both types of work-family conflict on withdrawal behaviors. Theoretical and practical implications of the study of work-family conflict crossover effects on withdrawal behaviors at work are discussed.  相似文献

Black and White women may experience feminist identity development differently, and the womanist (Ossana, Helms, & Leonard, 1992) and feminist (Downing & Roush, 1985) identity development models may differ in their ability to capture those experiences. Black (n = 29) and White (n = 94) female college students completed a questionnaire that included feminist identity, womanist identity, and self-esteem scales. Results provided partial support for the hypothesis that Black women would agree more strongly with the womanist model, whereas White women would agree more strongly with the feminist model. In addition, the womanist model better differentiated between stages of identity development than did the feminist model for Black women. Results also partially supported the hypothesis that race would moderate the relationships between the womanist and feminist identity models and self-esteem.  相似文献

The aim of this work was to test the antiaggressive effects of lorazepam and to determine whether these effects were mediated by benzodiazepine receptors. In a first experiment, male mice were injected with lorazepam in a range of low doses (0.05, 0.1, 0.2, and 0.6 mg/kg) or saline solution. In a second experiment, 1 mg/kg of Ro 15‐1788, a benzodiazepine receptor antagonist, and a saline solution were injected before the behavioral test. Results showed that 0.6 mg/kg of lorazepam was the only dose that decreased the total duration of threat (P < .01) and social investigation (P < .05) and that 1 mg/kg of Ro 15‐1788 had no effects. In the third experiment, animals received two injections: 0.6 mg/kg of lorazepam plus 1 mg/kg of Ro 15‐1788, 0.6 mg/kg of lorazepam plus saline solution, or saline solution plus saline solution. Those treated with lorazepam and saline solution spent less time digging (P < .001), threatening (P < .001), and attacking (P < .05) and more time avoiding the opponent (P < .01) or being immobile (P < .001) than the controls. Ro 15‐1788 was successful in completely antagonizing the behavior modulated by lorazepam. Aggr. Behav. 28:248–256, 2002. © 2002 Wiley‐Liss, Inc.  相似文献

Is a man’s sexual peak earlier than a woman’s? Three studies were conducted to examine (a) whether the perception that men achieve their sexual peak at a younger age than do women is shared across individuals of different ages and sexes, (b) whether sexual peak is defined differently for men and women, and (c) whether differences between definitions contribute to differences in the age at which men and women are perceived to reach sexual peak. Study 1 suggested that participants believed that females reach their sexual peak at an older age than do males. Study 2 indicated that the defining feature of sexual peak for males was sexual desire and for females was sexual satisfaction. Study 3 suggested that predictions of male sexual peak coincided with participants’ predictions of male age of highest desire and frequency, but not satisfaction, and that female sexual peak coincided with participants' predictions of female age of highest satisfaction but not frequency or desire. Discussion focuses on potential reasons for differences between the perception of male and female sexuality, as well as the social and evolutionary importance of each of the dimensions of sexuality for both males and females.  相似文献

Through its explorations of the work of peace in Sri Lanka, Qadri Ismail's Abiding by Sri Lanka offers both a reconceptualization of democracy and a critique of certain academic disciplines as antithetical to peace and opposition to colonialism. This article considers his criticisms of history and anthropology in order to ask whether, in his terms, it would be possible to have a postcolonial, postempiricist analysis of religion. An exploration of the problems that the study of religion, specifically the category of religion and production of religious authority, pose for Ismail's criteria of postcolonial scholarship points toward the limitations of academic disciplinarity.  相似文献

Family members of people with serious mental illnesses (SMI) need information and support to cope with the considerable stresses they experience. The Family to Family Education Program (FtF) is a structured, peer-led, 12-week information and support self-help class for such individuals. Previous research by Dixon et al. (2004) shows reduced subjective burden and increased empowerment among graduates. The present study sought to understand what processes take place during FtF participation that might lead to these benefits, as a first step in building a conceptual model of how FtF causes its effects, using semi-structured interviews with 31 FtF graduates. Qualitative data analysis suggested that new factual and emotional information from FtF shifts interviewees' understanding of their situation and that skills acquired through FtF then allow participants to incorporate these new perspectives into more adaptive behaviors. These changes led to both proximal and distal benefits for the FtF participants interviewed. The results are discussed in the context of self-help, stress-and-coping, and trauma recovery theories.  相似文献

Cognitive processes mediated by the hippocampus and cortex are influenced by estradiol (E2); however, the mechanisms by which E2 has these effects are not entirely clear. As such, studies were conducted to begin to address the role of actions at the β form of the intracellular estrogen receptor (ERβ) for E2’s cognitive effects in adult female mice. We investigated whether E2 improved performance of wild type (WT) and ERβ knockout (βERKO) mice in tasks considered to be mediated by the cortex and hippocampus, the object recognition and object placement tasks. WT and βERKO mice were ovariectomized (ovx) and E2 (0.1 mg/kg), an ERβ selective ER modulator (SERM), diarylpropionitrile (DPN; 0.1 mg/kg), or oil vehicle was administered to mice following training in these tasks. We hypothesized that if E2 has mnemonic effects, in part, due to its actions at ERβ, then WT mice administered E2 or DPN would have improved performance compared to vehicle WT controls, which would not be different from βERKO mice administered vehicle, E2 or DPN. Alternatively, activation of ERα (with E2, which is a ligand for both ERα and ERβ) may produce opposing effects on cognition and/or the activation of ERα and ERβ vs. either receptor isoform alone may produce a different pattern of effects. Results obtained supported the hypothesis that ERβ activation is important for mnemonic effects. Ovx WT, but not βERKO, mice administered E2 or DPN had a greater percentage of time exploring a novel object in the object recognition task and a displaced object in the object placement task. Thus, actions at ERβ may be important for E2 or SERMs to enhance cognitive performance of female mice in the object recognition and placement tasks.  相似文献

Given the importance of early prevention and intervention strategies for children exposed to trauma, detection of early risk factors for exposure to traumatic events in childhood is critical. The present study examined associations between three known prenatal risk factors that characterize environmental instability in utero—prenatal substance exposure, prenatal violence victimization, and unintended pregnancy—and child exposure to interparental violence and other adverse experiences in a sample of 198 mother–child dyads (M child age = 44.48 months) referred to a hospital clinic for treatment following exposure to trauma. Prenatal substance and violence exposure were associated with child trauma exposure, and prenatal violence victimization was also associated with maternal severity ratings of traumatic exposures. Unintended pregnancy was not associated with child trauma exposure or severity. These findings expand our understanding of prenatal risk factors for trauma exposure in childhood and, specifically, highlight prenatal substance exposure and violence victimization as risk factors for subsequent exposure to trauma in early childhood. Results suggest that prenatal prevention and intervention programs should target reducing maternal substance use and in-utero exposure to violence.  相似文献

The current study questions whether organizational perceptions of family supportiveness predict work-family conflict (WFC) and job satisfaction for an atypical sample of male hourly workers in a manufacturing organization, and whether those relationships depend on work (number of work hours) and family (number of family roles) demands. A unidimensional factor structure for the family supportiveness scale was not found; however a subscale for the extent that the organization supported work-family balance was strongly related to WFC and job satisfaction. An interaction was found such that those working long hours in the family-supportive work environment had lower WFC than those working long hours in an unsupportive environment, while the number of family roles (e.g., spouse, parent, eldercare) had no moderating effects. Supporting employees’ non-work life is determined to be important for these employees.  相似文献
