Patients referred for genetic counseling may be in a state of crisis, feeling as though they are incapable of making decisions about the management of their pregnancy, genetic testing options and/or life planning issues. The role of the genetic counselor is to assist a patient through this crisis state by increasing the patient's understanding and by helping to facilitate decision making and adjustment to those decisions. In this paper we present a clinical genetic counseling case that was complicated by numerous medical and psychosocial issues. The wide scope of this case required the involvement of both a prenatal and a medical genetic counselor. Working as a team we utilized a crisis intervention model. Our counseling focused on identifying and isolating the issues, providing factual information, setting a time frame for decisions to be made, and encouraging social support and emotion-focused coping strategies. 相似文献

In this study we examined covariation assessments made using real‐world information held by individual participants about an important preventive health behaviour: receiving an influenza vaccine (‘flu shot’). Four hundred and seventy‐seven healthy adult participants completed a questionnaire, indicating both their personal experience and vicarious experience (knowledge of other people's experiences) with the flu shot and the flu. Additionally, participants provided a covariation assessment by indicating how effective they thought the flu shot is in preventing the flu. We examined whether the experience information was related to the covariation assessment, and whether it in turn was related to the decision to receive a flu shot. Our results indicated that people use a simple intuitive strategy to combine their personal experience information. For vicarious experience information, we found evidence for use of a normative strategy, as well as simpler intuitive strategies. Consistent with our hypothesis, both types of experience information were associated with the effectiveness judgement, which was subsequently related to the decision to obtain a flu shot. Practical applications of these findings are discussed. Copyright © 2002 John Wiley & Sons, Ltd. 相似文献

- This paper builds on the concept of conspicuous donation behaviour (CDB) through further conceptualisation and operationalisation of this construct. The paper reports on developing the CDB scale via a three‐stage process, which includes five data collections using a total of 1311 respondents. The data analysis indicates that the resulting eight‐item (two factor) CDB scale has face, content, convergent, discriminant and predictive validity and the CDB scale is reliable across samples. The CDB scale has the potential for significant usage in the development and testing of theory, as well as in practical applications.

Using Ecological Systems Theory and stage sequential modelling procedures for detecting mediation, this study examined how early developmental contexts impact preschoolers' performances on a measure of sustained attention and impulse control. Data from 1273 European‐American and African‐American participants in the NICHD Study of Early Child Care were used to identify the potential mediators of the relation between early household income‐to‐need (INR) and 54‐month impulsivity and inattention. Exploratory analyses were also conducted to determine whether the relationships between early income, home environment, parenting stress, and the outcome variables differ for African‐American versus European‐American‐American children. We found modest support for the study hypothesis that 36‐month home environment quality mediated the INR/attention relationship. INR accounted for more home environment score variance and home environment accounted for more Impulsivity score variance for African‐American children. Home environments were related to inattention in the European‐American, but not African‐American, group. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

A prior experimental evaluation of a community-based advocacy program for women with abusive partners demonstrated positive change in the lives of women even 2 years postintervention (C. M. Sullivan & D. I. Bybee, 1999). The current study explored the complex mediational process through which this change occurred, using longitudinal structural equation modeling and formal tests of mediation. As hypothesized, the advocacy intervention first resulted in women successfully obtaining desired community resources and increasing their social support, which enhanced their overall quality of life. This improvement in well-being appeared to serve as a protective factor from subsequent abuse, as women who received the intervention were significantly less likely to be abused at 2-year follow-up compared with women in the control condition. Increased quality of life completely mediated the impact of the advocacy intervention on later reabuse. Discussion places advocacy for women in the context of other efforts that are needed to build an effective community response to preventing intimate violence against women. 相似文献

We investigated the joint mediating effects of injuries and stress on the relationship between abuse and women's health. A community sample of 397 women, half of whom had been assaulted by an intimate partner within the prior 6 months, was interviewed about their experience of intimate partner violence, injuries, stress, income, depression, and physical health problems. Structural equation modeling techniques confirmed the complex model of hypothesized indirect effects of abuse on women's physical health problems through injuries, stress, and depression. Stress accounted for 80% of the indirect effect of abuse on women's physical health. Its direct effect on physical health was somewhat larger than its indirect effect through depression, but both processes played a key role in determining the effect of abuse on women's physical health problems. Furthermore, abuse was a stronger predictor of women's stress than was poverty. Implication and future research are discussed. 相似文献

Two experiments investigated the hypothesis that arm crossing serves as a proprioceptive cue for perseverance within achievement settings. Experiment 1 found that inducing participants to cross their arms led to greater persistence on an unsolvable anagram. Experiment 2 revealed that arm crossing led to better performance on solvable anagrams, and that this effect was mediated by greater persistence. No differences in comfort, instruction adherence, or mood were observed between the arms crossed and control conditions, and participants appeared to be unaware of the effect of arm crossing on their behavior. Implications of the findings are discussed in terms of the interplay between proprioceptive cues and contextual meaning. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

In naming artifacts, do young children infer and reason about the intended functions of the objects? Participants between the ages of 2 and 4 years were shown two kinds of objects derived from familiar categories. One kind was damaged so as to undermine its usual function. The other kind was also dysfunctional, but made so by adding features that appeared to be intentional. Evidence that 2‐, 3‐ and 4‐year‐olds were more likely to apprehend the broken objects than the intentionally dysfunctional objects as members of the familiar lexical categories favors the conclusion that, in naming, children may spontaneously infer and reason about design intentions from an early age. This is the first evidence that 2‐ and 3‐year‐olds not only take design intentions into account in object categorization, but that they do so even without explicit mention of the objects’ accidental or intentional histories. The results cast doubt on a proposal that young children's lexical categorization is based on automatic, non‐deliberative processes. 相似文献

We evaluated the efficacy of a brief staff-training procedure to increase the use of graduated prompting by 2 certified nursing assistants (CNAs) while they helped to dress 3 persons with dementia in a seven-bed dementia care unit. The multiple baseline design across participants showed that CNAs dressed residents with minimal resident involvement during baseline observations. Following brief in-service training, CNAs provided graduated prompts and praise appropriately, suggesting that CNAs can promote active involvement in personal care routines by older adults with dementia. 相似文献

The interplay between two perspectives that have recently been applied in the attitude area—the social identity approach to attitude‐behaviour relations (Terry & Hogg, 1996 ) and the MODE model (Fazio, 1990a )—was examined in the present research. Two experimental studies were conducted to examine the role of group norms, group identification, attitude accessibility, and mode of behavioural decision‐making in the attitude‐behaviour relationship. In Study 1 (N = 211), the effects of norms and identification on attitude‐behaviour consistency as a function of attitude accessibility and mood were investigated. Study 2 (N = 354) replicated and extended the first experiment by using time pressure to manipulate mode of behavioural decision‐making. As expected, the effects of norm congruency varied as a function of identification and mode of behavioural decision‐making. Under conditions assumed to promote deliberative processing (neutral mood/low time pressure), high identifiers behaved in a manner consistent with the norm. No effects emerged under positive mood and high time pressure conditions. In Study 2, there was evidence that exposure to an attitude‐incongruent norm resulted in attitude change only under low accessibility conditions. The results of these studies highlight the powerful role of group norms in directing individual behaviour and suggest limited support for the MODE model in this context.
