In this article, we review past studies comparing randomized experiments to regression discontinuity designs, mostly finding similar results, but with significant exceptions. The latter might be due to potential confounds of study characteristics with assignment method or with failure to estimate the same parameter over methods. In this study, we correct the problems by randomly assigning 588 participants to be in a randomized experiment or a regression discontinuity design in which they are otherwise treated identically, comparing results estimating both the same and different parameters. Analysis includes parametric, semiparametric, and nonparametric methods of modeling nonlinearities. Results suggest that estimates from regression discontinuity designs approximate the results of randomized experiments reasonably well but also raise the issue of what constitutes agreement between the 2 estimates. 相似文献

Theorists contend that emotional awareness is vital to being able to use emotional information adaptively. The extent to which individuals attend to and value their feelings, or attention to emotion, is a facet of emotional awareness. Little research, however, has examined whether attention to emotion affects the magnitude or intensity of emotional experiences. In the present study we examined the relations between attention to emotion and levels of affect in 53 healthy adults. Participants carried hand-held electronic devices for approximately 7 days and were randomly prompted eight times per day to answer a series of questions. At each prompt, participants reported attention to emotion, current negative affect (NA), and positive affect (PA). All findings presented were computed using multilevel modeling. Replicating findings obtained using trait-level measures, we found that attention to emotion was associated concurrently with higher levels of both NA and PA. We also found prospectively that attention to emotion at one prompt predicted a decrease in levels of NA, but no change in levels of PA, at the subsequent prompt. These findings suggest that emotional processes serve different functions over time and highlight the role of attention to emotion in affect regulation.

An experience sampling study examined the degree to which feeling stereotyped predicts feelings of low power and inhibition among stigmatized and nonstigmatized individuals. For 7 days, participants with a concealable (gay and lesbian), a visible (African American), or no identifiable stigma recorded feelings of being stereotyped, of powerlessness, and of inhibition immediately following social interactions. For members of all three groups, feeling stereotyped was associated with more inhibition, and this relation was partially mediated by feeling low in power. Although stigmatized participants reported feeling stereotyped more often than nonstigmatized participants, they reacted less strongly to the experience, consistent with the presence of buffering mechanisms developed by those living with stigma. African Americans appeared to buffer the impact of feeling stereotyped more effectively than gay and lesbian participants, an effect that was partly attributable to African Americans' higher identity centrality. 相似文献

A preference for cradling infants on the left side has been demonstrated in women, as has a relation of reduced left-cradling and stress/negative affect. This relation has not yet been investigated in male participants. Due to less left-cradling in non-fathers compared to fathers it was suggested that fatherhood might have an influence on cradling behavior. The present study investigated the cradling preference of first- and multi-time parents before and after birth, and its relation to ill-being and stress. Results revealed that cradling behavior of first-time fathers was not different before and after the birth of the infant. Thus, fatherhood does not seem to have an acute influence on cradling behavior. Furthermore, cradling behavior of first- and multi-time parents was differentially influenced by ill-being and stress.These results present new information about the course of cradling preference from pregnancy to postpartum and indicate that the relation of cradling and ill-being/stress is more complex for parents than for non-parents. 相似文献

In this article, the authors consider strategies for counseling female Muslim clients. First, they review general beliefs and practices of Muslims in the United States. Through the use of a case study, they illustrate a collaborative method of counseling Muslim women that is based on a trusting client‐counselor relationship. 相似文献

Motor timing is essential for performing self-initiated movement sequences. Here, we investigated how sequence rhythm, or the timing for co-ordinating movements within a sequence, contributes to action preparation, compared with other processes occurring during sequence planning. First, we recorded the readiness potential (RP) in a condition of complex sequence rhythm and in condition of high demand on the timing for sequence initiation. We found that sequence rhythm and sequence initiation are independent processes, with sequence initiation contributing to early RP. Second, we compared the RP recorded in a condition of complex sequence rhythm and in a condition of complex sequence order, in which a complex combination of finger sub-movements had to be correctly ordered within a sequence. We found that sequence rhythm and sequence order share common processes occurring late RP. We suggest that the preparation for movement involves independent processes devoted to different aspects of motor timing and sequencing. 相似文献

Objectives
The aim of this study was to determine rates of psychooncological care for cancer inpatients and outpatients under routine conditions in a large University hospital. The percentage of patients who received care was analyzed and compared with self-rated and expert rated supportive care needs.Methods
The percentage of inpatients who received psychooncological care was calculated by comparing the number of cancer patients treated at the hospital as documented by the local tumor registry (n=1,979) with the number of patients treated by a psychooncologist in that hospital as documented by the hospital??s psychooncological consultation liaison service. The percentage of outpatients who received psychooncological care was calculated by comparing the number of incident cancer cases as documented by the local tumor registry (n=5,886) with the number of patients who received at least one consultation at the local tumor counseling centre. Supportive care needs were estimated by analyzing data of a prospective patient survey in the same hospital (n=1,803) using the Hospital Anxiety and Depression Scale and single items to determine social burden and the wish for emotional support.Results
The results showed that 11% of inpatients and outpatients (n=234 and n=638, respectively) received psychooncological care. Social care needs were prevalent in 37% and psychological care needs in 52% of the patients during the stay in hospital and in 42% (social and psychological) 6 months later. Of the patients 41% expressed the need to see a social worker and 29% to see a psychologist. Large differences were found between patients with different tumor entities.Conclusion
Psychooncological care delivered to cancer patients under routine conditions was below the actual rate required as estimated by screening instruments and as expressed by the patients. 相似文献870.

Fatigue is a serious cancer-related syndrome reported by cancer patients during and after treatment. Especially the impact of chronic fatigue on quality of life is substantial. The aim of this study was to identify predictors of fatigue after finishing treatment from an early stage of the cancer treatment. A sample of 551 cancer patients with heterogeneous diagnoses completed questionnaires assessing fatigue, psychological and psychosomatic data plus treatment data. The patients were recruited from an acute care hospital (t1) and the participants completed the questionnaire 2?C2.5 years after treatment (t2). Regression analysis showed that the strongest predictor of later fatigue was fatigue during the therapy. Other impact factors are radiotherapy and pain. The results suggest that the diagnosis and treatment of acute fatigue should be carried out at an early stage of cancer treatment to prevent chronic fatigue. Suitable diagnostic methods and treatment options will be presented. 相似文献
