Couples with the greatest need for relationship health maintenance and intervention are often least able to afford and access it; therefore, accessible, affordable, effective, and brief interventions are needed to improve relationship health for those who need it most. Consequently, this paper examined whether a brief relationship intervention could be effectively implemented with a low‐income, underserved population. All enrolled participants (= 1,312) received the Relationship Checkup, which consists of an assessment and a feedback session delivered in their homes or at a local clinic at their request. Measures assessed relationship satisfaction, communication, psychological and physical aggression, and intimacy at baseline and 1‐month follow‐up, and program and relationship satisfaction at 6‐month follow‐up. All participants reported significant improvements on all outcomes with small effect sizes. However, moderation analyses suggested that distressed couples reported significantly larger effects across the board. Overall, participants reported that they were highly satisfied with the intervention both immediately after its delivery and 6 months later. Findings provide preliminary support for the effectiveness of this brief checkup and point to the utility of offering these kinds of low‐cost brief interventions in flexible formats for those who might have the most difficulty accessing them.  相似文献

In the present prospective study of 81 older volunteers from a nonprofit organization in Australia, the authors compared the predictive utility of I. Ajzen's (1988) theory of planned behavior with that of E. G. Clary and M. Snyder's (1991) functional approach to volunteering. The authors mailed questionnaires to 385 volunteers in two waves of data collection. The first wave measured theory-of-planned-behavior variables and functional-approach variables. The second wave measured self-reported volunteering behavior for the previous month. Regression analyses supported both the theory of planned behavior and the functional approach; the theory of planned behavior accounted for a significantly larger proportion of variance in above-average participation in self-reported volunteerism. The findings of the present study provided some support for both the theory of planned behavior and the functional approach as models of self-reported volunteerism.  相似文献

Childhood temperament and family environment have been shown to predict internalizing and externalizing behavior; however, less is known about how temperament and family environment interact to predict changes in problem behavior. We conducted latent growth curve modeling on a sample assessed at ages 5, 7, 10, 14, and 17 (N = 337). Externalizing behavior decreased over time for both sexes, and internalizing behavior increased over time for girls only. Two childhood variables (fear/shyness and maternal depression) predicted boys' and girls' age-17 internalizing behavior, harsh discipline uniquely predicted boys' age-17 internalizing behavior, and maternal depression and lower family income uniquely predicted increases in girls' internalizing behavior. For externalizing behavior, an array of temperament, family environment, and Temperament × Family Environment variables predicted age-17 behavior for both sexes. Sex differences were present in the prediction of externalizing slopes, with maternal depression predicting increases in boys' externalizing behavior only when impulsivity was low, and harsh discipline predicting increases in girls' externalizing behavior only when impulsivity was high or when fear/shyness was low.  相似文献

This study addresses continuing controversies concerning the nature of semantic impairment in early dementia of the Alzheimer type (DAT), and the relationship between conceptual knowledge and picture naming. A series of analyses of fine-grained feature knowledge data show that: (1) distinctive features of concepts were more vulnerable than shared; (2) the amount of attribute knowledge about a concept was associated reliably, and in a graded fashion, with the ability to name a picture of that item; (3) sensory features were differentially important in naming; and (4) the degree of disruption to different types of attribute knowledge did not vary between items from living and nonliving domains. These findings are discussed in the context of contemporary cognitive and computational models of semantic memory organisation.  相似文献

Past research has shown that people typically underestimate the cumulative risk of events. This effect has mainly been interpreted as resulting from the use of cognitive heuristics and judgment strategies, such as availability or anchoring and adjustment. The authors suggest that motivational processes can be an additional force in the generation of cumulative risk estimates. Using an experimental design, Study 1 shows that people underestimate the cumulative risk of infection with sexually transmitted diseases of appealing prospective sexual partners by using risk-irrelevant information for their judgment. Using a correlational design, Study 2 demonstrates that people underestimate the cumulative risk of being infected with a sexually transmitted disease and that commitment to the present partner is directly related to a low cumulative risk estimate as well as indirectly through its effect on the perceived risk of the present partner. Together, the two studies demonstrate that motivation influences the underestimation of cumulative risk.  相似文献

The measurement of posttraumatic stress disorder (PTSD) is critically important for the identification and treatment of this disorder. The PTSD Checklist (PCL; F. W. Weathers and J. Ford, 1996) is a self-report measure that is increasingly used. In this study, the authors investigated the factorial validity of the PCL with data from 236 cancer survivors who received a bone marrow or stem cell transplantation. The authors examined the fit of these data with the clinical model of 3 symptom clusters for PTSD, as proposed in the Diagnostic and Statistical Manual of Mental Disorders, and alternative models tested in prior research. By using confirmatory factor analysis the authors found that a 4-first-order-factor model of PTSD provided the best fit. The relations of PTSD symptoms with sociodemographic and medical variables were also explored.  相似文献

The present research tested the extent to which perceptions of early childhood experiences with parents predicted general views of the self (i.e., self‐esteem) and others (i.e., humanity‐esteem), and whether attachment self‐ and other‐models mediated these links. Two studies used a new measure of humanity‐esteem (Luke & Maio, 2004) to achieve these ends. As expected, indices that tapped a positive model of the self in relationships were associated with high self‐esteem and indices that tapped a positive model of others in relationships were associated with high humanity‐esteem. Also, early attachment experiences with fathers and mothers predicted self‐esteem and humanity‐esteem, respectively, and these direct relations were mediated by the attachment models. The studies, therefore, provide direct evidence that attachment measures predict general favorability toward the self and others, while revealing novel differences in the roles of childhood experiences with fathers and mothers.

A prevalent assumption in text comprehension research is that many aspects of text processing are automatic, with automaticity typically defined in terms of properties (e.g., speed and effort). The present research advocates conceptualization of automaticity in terms of underlying mechanisms and evaluates two such accounts, a computational-efficiency account (underlying computational processes become more efficient with practice) and a memory-based processing account (the underlying basis of processing shifts with practice, from computing interpretations to retrieving prior interpretations). In five experiments, short texts containing either an ambiguous or unambiguous syntactic structure were presented for multiple study trials. In both conditions, reading times in target regions decreased across trials, indicating automatization. Several findings supported the memory-based processing account (e.g., practice effects were largely item-specific, reading times were longer for ambiguous versus unambiguous sentences on early trials but converged on later trials) Some evidence was also found for a contribution of gains in computational efficiency (i.e., some item-general practice effects were observed). Implications for research on automaticity and text processing are discussed.  相似文献

This article presents and discusses four clinical cases that exemplify the complexity of ethical dilemmas concerning the provider's obligation to disclose or withhold genetic information from patients. Case 1: What is the responsibility of the cancer genetics provider to ensure that a positive test results is shared with distant relatives? Case 2: To ensure that results go to at-risk relatives, do we have the right to ignore the wishes of the designated next-of-kin? Case 3: Do we have the right to reveal a familial BRCA1 mutation to a patient's relative, who is at 50% risk? Case 4: Do we have an obligation to reveal that a patient is not a blood relative and therefore, not at risk to have inherited a familial mutation? These cases form the basis for discussing the provider's dual obligations to keeping patient confidentiality and informing patients and families about risk (i.e. duty to warn). We also provide a summary of consensus points and additional discussion questions for each case.  相似文献

Previous research investigating the influence of perceived physical attractiveness on student evaluations of college professors has been limited to a handful of studies. In this study, the authors used naturally occurring data obtained from the publicly available Web site www.ratemyprofessors.com. The data suggested that professors perceived as attractive received higher student evaluations when compared with those of a nonattractive control group (matched for department and gender). Results were consistent across 4 separate universities. Professors perceived as attractive received student evaluations about 0.8 of a point higher on a 5-point scale. Exploratory analyses indicated benefits of perceived attractiveness for both male and female professors. Although this study has all the limitations of naturalistic research, it adds a study with ecological validity to the limited literature.  相似文献
