Three studies examined strategies of status improvement in experimentally created (Study 1 and 2) and preexisting (Study 3) low-status groups. Theory and prior research suggested that an in-group norm that established a particular strategy of status improvement as moral (rather than competent) would have a greater effect on individuals' decision to work at this strategy. Both Study 1 and Study 2 found that morality norms had a greater impact than competence norms on individuals' decision to work at group (rather than individual) status improvement. In both studies participants also needed less time to decide on a strategy of status improvement when it is was encouraged by a morality norm rather than a competence norm. Study 3 used a preexisting low-status group (i.e., Southern Italians) to further confirm that morality norms have a greater effect on the decision to work at group status improvement than do competence norms. Results are discussed in terms of social influence and identity management strategies. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Objective: To examine the longitudinal relationships between parent and child distress in a sample of children with juvenile rheumatic diseases (JRDs). Design: Cross-lagged panel correlation analysis tested the temporal precedence of parent distress versus child distress over a 1-year period. Participants: Thirty-seven children (ages 9–17 years; 22 girls) diagnosed with JRD and their parents completed self-report measures on 2 occasions (assessment interval M = 12 months). Primary Outcome Measures: Child Depression Inventory and Brief Symptom Inventory. Results: Significant cross-sectional parent–child distress associations were observed at both time points. Moreover, Time 1 parent distress predicted child distress at Time 2 after child-reported functional ability was controlled; Time 1 child distress was unrelated to Time 2 parent distress. Cross-lagged panel correlations demonstrated the temporal precedence of parent distress relative to child distress in the parent–child distress relationship. Conclusions: These preliminary findings underscore the importance of parent distress in parent–child transactional adjustment, and suggest a predominant role for parent distress in children's adjustment to JRDs.

Previous researchers have proposed that the time and energy involved in family and paid work should affect the relationship between stressors and conflict in both the work and family domains. Using a sample of 113 registered nurses, the authors hypothesized that the amount of time and involvement in both domains would moderate the stressor–conflict relationships. Results supported many of the interactions in predicting conflict in each domain, and implications for the health of working women with family responsibilities were discussed.

CONTEXT: Nearly all managed care plans rely on a physician "gatekeeper" to control use of specialty, hospital, and other expensive services. Gatekeeping is intended to reduce costs while maintaining or improving quality of care by increasing coordination and prevention and reducing duplicative or inappropriate care. Whether gatekeeping achieves these goals remains largely unproven. OBJECTIVE: To assess physicians' attitudes about the effects of gatekeeping compared with traditional care on administrative work, quality of patient care, appropriateness of resource use, and cost. DESIGN: Cross-sectional survey of primary care physicians SETTING: Outpatient facilities in metropolitan Boston, Mass. PARTICIPANTS: All physicians who served as both primary care gatekeepers and traditional Blue Cross/Blue Shield providers for the employees of Massachusetts General Hospital, Boston. Of the 330 physicians surveyed, 202 (61%) responded. OUTCOMES MEASURES: Physician ratings of the effects of gatekeeping on 21 aspects of care, including administrative work, physician-patient interactions, decision making, appropriateness of resource use, cost, and quality of care. RESULTS: Physicians reported that gatekeeping (compared with traditional care) had a positive effect on control of costs, frequency, and appropriateness of preventive services and knowledge of a patient's overall care (P<.001). They also felt that gatekeeping increased paperwork and telephone calls and negatively affected the overall quality of care, access to specialists, ability to order expensive tests and procedures, freedom in clinical decisions, time spent with patients, physician-patient relationships, and appropriate use of hospitalizations and laboratory tests (P<.001). Overall, 32% of physicians rated gatekeeping as better than traditional care, 40% the same, 21% gatekeeping as worse, and 7% were of mixed opinion. Positive ratings of gatekeeping were associated with fewer years in clinical practice, generalist training, and experience with gatekeeping and health maintenance organization plans. CONCLUSIONS: Physicians identified both positive and negative effects of gate-keeping. Overall, 72% of physicians thought gatekeeping was better than or comparable to traditional care arrangements.  相似文献

One of the most consistent findings in psychiatric research is that rates of major depression are at least twofold higher among women than among men. Although there is considerable agreement in the literature that life events play a role in producing, triggering, or maintaining episodes of depression, less is known about the relationship among gender, life events, and depression. In the present study, we compared the rates, focus ("interpersonal" vs. "non-interpersonal"), and timing of stressful life experiences reported in rigorous interviews of male and female patients with unipolar recurrent depression and nondepressed contrast subjects. Consistent with hypotheses, female patients were more likely to experience stressful life experiences than their male counterparts; rates of stressful life experiences did not differ between female and male controls. Unexpectedly, rates of interpersonal stress did not differ among males and females regardless of patient or control status. We also found no significant differences in the timing of pre-onset events: stressful events were generally concentrated in the period immediately preceding onset for both men and women. Thus, although these data suggest that life stress may play a larger role in the provocation of recurrent episodes of depression for women than for men, there do not seem to be sex differences in the extent to which interpersonal vs. noninterpersonal events and difficulties are associated with depression onset or in the temporal distribution of events. Implications of these results are discussed in the context of research on other putative factors contributing to gender differences in rates of depression.  相似文献

Previous research pertaining to job performance and voluntary turnover has been guided by 2 distinct theoretical perspectives. First, the push–pull model proposes that there is a quadratic or curvilinear relationship existing between these 2 variables. Second, the unfolding model of turnover posits that turnover is a dynamic process and that a downward performance change may increase the likelihood of organizational separation. Drawing on decision theory, we propose and test an integrative framework. This approach incorporates both of these earlier models. Specifically, we argue that individuals are most likely to voluntarily exit when they are below-average performers who are also experiencing a downward performance change. Furthermore, the interaction between this downward change and performance partially accounts for the curvilinear relationship proposed by the push–pull model. Findings from a longitudinal field study supported this integrative theory. (PsycINFO Database Record (c) 2011 APA, all rights reserved)  相似文献

This study investigated links between maternal employment and fathers' parenting quality when their infants were 4 and 12 months old. Sixty-three fathers were videotaped interacting with their infants and completed questionnaires regarding their involvement in caregiving, parenting stress, and marital quality, and mothers reported on children's temperament. Fathers whose wives either did not work outside the home or worked part time were more sensitive and responsive to their children when they were more involved in caregiving; men whose wives worked full time exhibited more negative affect and behavior when they participated more in child care. Men whose wives were not employed also were more positive in their interactions when they were happier with their marriage, whereas men whose wives worked either part time or full time exhibited a negative relation between parenting behavior and marital quality. Maternal work circumstances were not related to fathers' parenting stress; rather, marital quality and child temperament predicted parenting stress at 4 and 12 months for all fathers.

In this study we examined the moderator role of coping (problem-, emotion-, and avoidance-focused coping strategies) between work-to-family and family-to-work conflict and well-being (work engagement, job satisfaction, and family satisfaction). The study was based on a sample of 527 Finnish workers. Hierarchical moderated regression analyses showed that emotion-focused coping buffered against job dissatisfaction in a high family-to-work conflict situation. On the other hand, emotion-focused coping was harmful for family satisfaction in the same stressful situation: Those who used more emotion-focused coping were less satisfied with their family life under the conditions of high family-to-work conflict. Furthermore, avoidance coping was beneficial in a high family-to-work conflict situation: Those who used more avoidance coping were more satisfied with their family life in this situation. No buffering effects were found for work engagement or for problem-focused coping. (PsycINFO Database Record (c) 2011 APA, all rights reserved)  相似文献

Four experiments investigated 3-year-olds' understanding of the appearance–reality distinction using both J. Flavell, F. Green, and J. Flavell's (1986) typical verbal response paradigm and a new, nonverbal response paradigm. Both paradigms require verbal questioning, but the former involves a verbal response and the latter a nonverbal one. In the nonverbal paradigm, children were shown a deceptive object and asked to respond, nonverbally, to 2 different functional requests, 1 concerning the object's apparent property and 1 its real property. In the verbal paradigm, children were asked to state what the object looked like and what it really was. In the verbal paradigm, children were about 30% correct (a rate matching that in the literature), whereas over 90% of the same children were correct in the nonverbal paradigm. Participating in the verbal paradigm first had a detrimental effect on the children's performance in the nonverbal paradigm, but the reverse order had no effect. These results suggest that 3-year-olds can represent two conflicting properties of a deceptive object and thus understand the appearance-reality distinction in the nonverbal domain.

Alcoholics Anonymous (AA) attendance is predictive of increased abstinence for many problem drinkers and treatment referral to AA is common. Strong encouragement to acquire an AA sponsor is likewise typical, and findings about the benefits associated with social support for abstinence in AA support this practice, at least indirectly. Despite this widespread practice, however, prospective tests of the unique contribution of having an AA sponsor are lacking. This prospective study investigated the contribution of acquiring an AA sponsor using a methodologically rigorous design that isolated the specific effects of AA sponsorship. Participants were recruited from AA and outpatient treatment. Intake and follow-up assessments included questionnaires, semi-structured interviews, and urine toxicology screens. Eligibility criteria limited prior treatment and AA histories to clarify the relationship of interest while, for generalizability purposes, broad substance abuse criteria were used. Of the 253 participants, 182 (72%) provided complete data on measures central to the aims of this study. Overall reductions in alcohol, marijuana, and cocaine use were found over 12-months and lagged analyses indicated that AA attendance significantly predicted increased abstinence. During early AA affiliation but not later logistic regressions showed that having an AA sponsor predicted increased alcohol-abstinence and abstinence from marijuana and cocaine after first controlling for a host of AA-related, treatment, and motivational measures that are associated with AA exposure or are generally prognostic of outcome.

An educational project in nursery schools was carried out with the aim to improve children's sleep. Its effectiveness was tested in terms of awareness of families and length of sleep of children. The method was a prevention trial based on the random division of classes of 3-year old into two groups (intervention group and control group) comprising children enrolled in nursery schools in the Rh?ne region (France) in 1992. The project, lasting 2 years, relied on physicians from the community (Maternal, Child Health Service and School Health Service), their role being to mobilise the teaching teams, distribute specific teaching tools and raise awareness of families to respect the sleep patterns of children, during routine medical examinations. The study was carried out in 140 nursery schools with 1,500 children in each group. The evaluation was based on the application of a logistical regression model taking potentially confounding factors into account, and an analysis in sub-groups in order to demonstrate the effectiveness of intervention on particularly exposed groups. The results show: 1) the feasibility of such an intervention among nursery school children on a large scale, 2) the effectiveness of the action, with a reduction of the risk of "poor knowledge" among parents (OR = 0.76), particularly in urban areas, and a reduction in the risk "short nights" in the sub-group of children who had " little sleep at 3 years" in low social class families (OR = 0.50).  相似文献

We have previously demonstrated that rats trained on a two-duration peak procedure in which two modal signals (i.e., tone and houselight) predicted probabilistic reinforcement availability at two times (10 s and 20 s) would respond in a scalar manner at a time between the trained durations in response to the simultaneous compound cue (tone + houselight). In these experiments, we evaluated whether this scalar response pattern would remain with greater relative separation between the anchor durations. Results revealed an effect of the modality–duration relationship, such that scalar responding was seen on compound trials in rats trained that the auditory stimulus signaled the shorter duration, whereas the visual stimulus signaled the longer duration, but not in the reverse condition. In rats showing scalar responding on compound trials, post hoc analyses demonstrated that the peak time of compound responding was most accurately predicted by the reinforcement probability weighted average of anchor peak times. In contrast, rats trained that the visual stimulus signaled the shorter duration, whereas the auditory stimulus signaled the longer duration, responded in a highly rightward skewed manner. In these rats, initiation of responding to the compound stimulus appeared to be controlled by the visual stimulus only, whereas response terminations reflected control by both modal stimuli. These latter data provide evidence of separate determinants of response initiation and termination. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

This article argues that in-group favoritism occurs on positive and negative dimensions only when the dimensions of comparison provide an appropriate and meaningful basis for self–other definition, that is, when traits comparatively and normatively fit in-group–out-group categorizations. Three studies are reported in which groups were evaluated on positive or negative traits that varied in their degree of normative fit to in-group and out-group identity. In line with predictions, fit rather than stimulus valence was the crucial determinant of (1) in-group favoritism and (2) absolute level of differentiation between groups. Implications of the findings for explanations of positive–negative asymmetry and broader understandings of intergroup discrimination are discussed.

This article explores the interplay between trust and conflict as antecedents of team effectiveness. In the first cross-sectional study, two alternative path models are tested in a sample of 174 teams (897 participants) with the emergent states of task conflict, relationship conflict, and trust acting as mediators between team demographic diversity (gender and nationality) on the one hand and perceived team effectiveness on the other. In one model trust is considered as an antecedent for the two types of conflict, while in the other the two types of conflict precede the emergence of trust. Although the fit indices for the model in which trust is considered the antecedent of conflict were slightly better, both models fitted the data well. The interdependence of trust and conflict was further explored in a second longitudinal study (49 teams), and the results showed that trust emerging in the initial team interaction phases is a good predictor for the emergence of both task and relationship conflict in further stages of team development.

The strangest things precipitate the most interesting discussions. It is interesting how frequently the word "older" appears in our language. It has been there all along, we have just become sensitized to its presence. The same may be true for you as you read the commentary on the next two pages and begin to reflect on the stereotypes and limitations placed on "older" people. Are they justified in the present day, or are they simply carryovers from the past, or is there some element of harsh reality to the characterizations?  相似文献

The medial preoptic area (mPOA) is a key site for the dopaminergic enhancement of male sexual behavior. Dopamine release increases in the rat mPOA with mating, supporting the critical stimulatory role played by preoptic dopamine on male sexual behavior. However, it has been questioned whether dopamine is specifically related to the occurrence of male sexual behavior and not simply involved in general arousal. To address this question, we asked whether dopamine release in the mPOA is linked to the production of male sexual behavior in Japanese quail (Coturnix japonica), a species that exhibits a much shorter temporal pattern of copulation than rats and does not have an intromittent organ, resulting in a very different topography of their sexual response. Extracellular samples from the mPOA of adult sexually experienced male quail were collected every 6 min before, during, and after exposure to a female using in vivo microdialysis and analyzed using high-performance liquid chromatography with electrochemical detection. Extracellular dopamine significantly increased in the presence of a female and returned to baseline after removal of the female. However, quail that failed to copulate did not display this increased release. These findings indicate that it is not solely the presence of a female that drives dopamine release in males, but how a male responds to her. Furthermore, in quail that copulated, dopamine release did not change in samples collected during periods of no copulation. Together, these findings support the hypothesis that dopamine action in the mPOA is specifically linked to sexual motivation and not only to copulatory behavior or physical arousal.

This investigation explores the contribution of two working memory systems (the articulatory loop and the central executive) to the performance differences between learning-disabled (LD) and skilled readers. Performances of LD, chronological age (CA) matched, and reading level-matched children were compared on measures of phonological processing accuracy and speed (articulatory system), long-term memory (LTM) accuracy and speed, and executive processing. The results indicated that (a) LD readers were inferior on measures of articulatory, LTM, and executive processing; (b) LD readers were superior to RL readers on measures of executive processing, but were comparable to RL readers on measures of the articulatory and LTM system; (c) executive processing differences remained significant between LD and CA-matched children when measures of reading comprehension, articulatory processes, and LTM processes were partialed from the analysis; and (d) executive processing contributed significant variance to reading comprehension when measures of the articulatory and LTM systems were entered into a hierarchical regression model. In summary, LD readers experience constraints in the articulatory and LTM system, but constraints mediate only some of the influence of executive processing on reading comprehension. Further, LD readers suffer executive processing problems nonspecific to their reading comprehension problems.  相似文献

Patients, employers, and third-party payers are all calling for improved measures of health care quality. This has led to the development of "report cards," assessments that are many times applied not just to health plans but also to providers. One attempt at creating a standardized set of quality and effectiveness measures is the Health Plan Employer Data and Information Set (HEDIS). The HEDIS measures are based primarily on analyses of administrative data sets. Problems with HEDIS measures, including the probability that plans will use different data collection methods and a lack of risk adjustment, may result in incorrect conclusions about the quality of care delivered by various providers. An alternative method of standardized surveys is proposed that will overcome many of the limitations of the current HEDIS measures, provide outcome rather than process data, and provide data for developing interventions to improve quality.  相似文献

[Correction Notice: An erratum for this article was reported in Vol 80(3) of Journal of Personality and Social Psychology (see record 2007-17568-001). The key coefficients on the diagonal paths were incorrect. The corrected figures in their entirety appear in the erratum.] This research tests a model suggesting that marital distress leads individuals to scrutinize of what is given and received in the relationship. This scrutiny elicits perceptions of unfairness that maintain or exacerbate marital distress. In a 3-panel longitudinal study tracking married couples across the transition to parenthood, both wives' and husbands' reports of marital conflict and wives' marital dissatisfaction at Time 1 positively predicted perceived unfairness of the allocation of household tasks at Time 2, controlling for earlier perceptions of unfairness. In addition, there was evidence of perceived unfairness of division of labor at Time 2 predicting marital conflict and marital dissatisfaction for wives at Time 3, controlling for earlier conflict and dissatisfaction. This model of relationship distress and perceptions of unfairness is contrasted with prior interpretations of links between perceived injustice and distress in relationships.

Few studies have examined nonshared environmental risk factors for disordered eating, and none have done so using a longitudinal design. The current project used a longitudinal, monozygotic twin differences design to examine parent–child conflict as a nonshared environmental risk factor for disordered eating. Participants included 468 monozygotic female twins (234 pairs) from the Minnesota Twin Family Study, who completed surveys every 3 years from ages 11 to 17 years. Twin differences in disordered eating were assessed with the Total Score, Body Dissatisfaction, Weight Preoccupation, and Binge Eating subscales of the Minnesota Eating Behavior Survey. Differences in parent–child conflict were assessed with the Parental Environment Questionnaire. Cross-lagged models were used to examine longitudinal associations among these variables, controlling for within-age associations. Only the longitudinal association between twin differences in disordered eating at age 14 years and differences in parent–child conflict at age 17 years were significant; twin differences in disordered eating predicted later differences in parent–child conflict rather than the reverse. Findings suggest differences in parent–child conflict between genetically identical twins may be a consequence of, rather than a risk factor for, differences in disordered eating.
