The present study investigated the relationships among ethnicity and social sharing of traumatic experiences in a sample of 88 East Asian and 88 European American women. Participants were asked to write about a traumatic experience for twenty minutes and then to rate how upsetting the experience was, how often they thought about it, how often and to whom they had previously disclosed the experience, as well as the perceived appropriateness of sharing the experience with different target audiences, e.g., friends and family members. The results indicated that Asian Americans reported speaking to others less frequently about the traumatic event and sharing it with fewer individuals, and tended to be more likely to share the event with friends than with family members when compared to European Americans. Asian Americans also reported thinking about the upsetting event less frequently than European Americans even though both groups reported that the events were equally upsetting. The more upsetting events were, the more often they were shared in the European American group, but there was no relationship between how upsetting events were and the degree to which they were shared in the Asian American group. 相似文献

How different amounts and components of treatment affect substance abuse treatment outcomes is fundamentally important to evaluating current treatment practices and recommending improvements. Through a secondary analysis of data from the National Treatment Improvement Evaluation Study (NTIES), the present study examined the relationships between treatment components, client-level factors, and positive treatment outcomes. Several components were shown tohave significant effects on the odds of a positive outcome, over and above the effects of client background characteristics. Depending on treatment modality, these included length of stay; whether or not clients reported seeing their treatment plan hours per month in group and individual counseling; utilization ofeducational, vocational, and other ancillary services; use of antianxiety and drug and alcohol medications; and client matching. Several interactions between client-level factors and treatment components were also observed. Studylimitations are discussed, followed by implications for policy and practiceand suggestions for further research. 相似文献

The purpose of this study was to investigate which social groups are perceived as a threat target and which are perceived as a threat source during the COVID-19 outbreak. In a German sample (N = 1454) we examined perceptions of social groups ranging from those that are psychologically close and smaller (family, friends, neighbors) to those that are more distal and larger (people living in Germany, humankind). We hypothesized that psychologically closer groups would be perceived as less affected by COVID-19 as well as less threatening than more psychologically distal groups. Based on social identity theorizing, we also hypothesized that stronger identification with humankind would change these patterns. Furthermore, we explored how these threat perceptions relate to adherence to COVID-19 health guidelines. In line with our hypotheses, latent random-slope modelling revealed that psychologically distal and larger groups were perceived as more affected by COVID-19 and as more threatening than psychologically closer and smaller groups. Including identification with humankind as a predictor into the threat target model resulted in a steeper increase in threat target perception patterns, whereas identification with humankind did not predict differences in threat source perceptions. Additionally, an increase in threat source perceptions across social groups was associated with more adherence to health guidelines, whereas an increase in threat target perceptions was not. We fully replicated these findings in a subgroup from the original sample (N = 989) four weeks later. We argue that societal recovery from this and other crises will be supported by an inclusive approach informed by a sense of our common identity as human beings. 相似文献

This paper reports on a workshop on Problem Formulation in Multi-Criteria Decision Analysis held at SPUDM97. The focus of the workshop was the problem formulation phase which occurs between the analyst meeting a person with a ‘mess’ and the time he or she begins to analyse a structured problem with several alternatives scored against several attributes or criteria. The objectives were: to share experience on procedures which might be transferable between the methodologies; to demonstrate different skills used by the analyst in structuring decision problems; and to catalyse a discussion on the problem formulation phase of an analysis. Three analysts, who generally approach problems using multiattribute methods, addressed the same problem. The problem used was constructed to be realistic to three decision makers, who had been trained in the issues of concern. There were two sessions. Each analyst was assigned a decision maker and formulated the problem independently in the first session, held in parallel. They were each observed by two observers and many of the audience at the workshop. The three formulations were presented along with the comments of the observers and discussed at a second plenary session. This paper reports the three formulations and observations, remarking on the ‘tricks of the trade’ employed by the analysts in formulating the problem. The analysts also describe their thinking and their aims in adopting their approach and style of interaction. More general remarks on the process of decision analysis are also offered. © 1998 John Wiley & Sons, Ltd. 相似文献

We sought to test within- and between- family associations of smoking during pregnancy (SDP) and attention deficit-hyperactivity disorder (ADHD) symptoms using a structured interview based on the conventional Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) symptoms and the Strengths and Weaknesses of ADHD-Symptoms and Normal-Behavior (SWAN) scale, which is a population based measure that grew out of the notion that an ADHD diagnosis exists on the extreme end of a continuum of normative behaviors and includes both above- and below- average performance on attention and activity. We used a sibling-comparison approach in a sample of 173 families including siblings aged 7–16 years (52% male) drawn from the state of Missouri, USA, wherein mothers smoked during one pregnancy but not the other. There was a within-family effect of smoking during pregnancy on SWAN hyperactivity/impulsivity and SWAN total ADHD behaviors. The associations between SDP and DSM-IV-based ADHD symptom dimensions as well as SWAN inattention were explained by familial confounds. These findings suggest that SDP exerts a potentially causal effect on increased ADHD hyperactive/impulsive behaviors and that this SDP effect is best captured when hyperactivity/impulsivity is assessed more normatively across the population, rather than specifically assessing problematic behaviors via DSM symptoms. Thus, any potentially causal effect of SDP on ADHD symptom dimensions may be restricted to hyperactive/impulsive behaviors rather than inattention, and normative, non-DSM-IV based behavioral measures may provide a more sensitive test of mechanisms of SDP-ADHD symptom associations, particularly in non-clinical samples. 相似文献

ABSTRACT The current study investigated whether a 5-month, adult mentoring intervention delivered by school personnel could enhance the school engagement of ninth grade urban minority adolescents. Compared to 20 at-risk students who did not receive an intervention, 20 at-risk students who were randomly assigned to mentoring exhibited significantly less decline during the first year of high school in perceived teacher support and decision making and were less likely to enter the discipline system. The effects were stronger and included sense of school belonging for participants who were “mentored as intended.” Moreover, mentee and mentor reports of relationship quality were associated with changes in mentored participants' school-related cognitions and behaviors. The findings indicate that adult mentoring may help to prevent normative declines in urban minority youths' school engagement. 相似文献
