Rape crisis volunteers who provide direct-care services to victims of sexual assault are a much-understudied group. Volunteers provide a crucial role in support of nonprofit rape crisis centers, and factors influencing their continued service are an important consideration for decision makers. In the present study, the authors examined--among volunteers providing hospital and crisis-line advocacy to victims of sexual assault--the training, service self-efficacy, social support, and experiences with victim blaming as correlates with overall satisfaction, affective commitment, and the intent to remain. Overall satisfaction and affective commitment were positively related to the intent to stay. Additionally, the perceived value of training was positively related to overall satisfaction and the intent to remain. 相似文献

This pilot study examined the internal consistency and concurrent validity of the Chinese version of the Acute Lower Back Pain Screening Questionnaire. A sample of 45 acute low back pain patients (27 men and 18 women; mean age = 47.8) were recruited from the Department of Orthopaedics and Traumatology of the Tuen Mun Hospital in Hong Kong. Three items of the original questionnaire were excluded from the analyses because response was low by 30 of the 45 patients. The questionnaire showed good internal reliability (Cronbach alpha = .88) and correlated significantly with other test scores: the Faces Pain Scale-Revised (alpha = .74), the Chinese (Hong Kong) SF-12 Health Survey (Mental subscale, alpha = -.47; Physical subscale alpha = -.62), and the Chinese Hospital Anxiety and Depression Scale (Anxiety subscale, alpha = .42; Depression subscale, alpha = .43). The questionnaire could be used in research and clinical work to provide data on the multicomponents of a pain experience as well as psychosocial risk factors related to pain among the Chinese. Researchers might examine the course of change in chronic pain. 相似文献

Use of complementary and alternative medicine (CAM) for treatment of attention-deficit hyperactivity disorder (ADHD) has become widespread in both referral and primary care populations. We review the purported mechanism of action and available evidence for selected CAM therapies for ADHD. Enduring controversies, such as elimination of artificial food additives, colors, and/or preservatives; the effect of sugar on behavior in children; and the use of EEG biofeedback, have been well studied but lack support as effective sole treatments for ADHD. The initial evidence for some emerging CAM therapies, such as essential fatty acid supplementation, yoga, massage, homeopathy, and green outdoor spaces, suggests potential benefits as part of an overall ADHD treatment plan. More rigorously designed studies are needed to evaluate their effectiveness as single therapy for ADHD. 相似文献

The purposes of this study were (a) to identify the primary institutional sources of articles to The Personnel and Guidance Journal/Journal of Counseling & Development from 1978 to 1993 (Volumes 57–71); (b) to identify the primary individual contributors to this journal during the survey period; (c) to identify and compare the program affiliations of individual contributors by editor during the survey period; and (d) to speculate as to whether the study results, collectively, indicate a trend toward more psychologists than counselors contributing to this journal. A total of 1,843 articles were reviewed. Of the 2,198 authors, 69% were academicians and 31% were practitioners. The data suggest that there has been a clear pattern of more psychologists than counselors contributing to this journal. 相似文献

Data are ipsative if they are subject to a constant-sum constraint for each individual. In the present study, ordinal ipsative data (OID) are defined as the ordinal rankings across a vector of variables. It is assumed that OID are the manifestations of their underlying nonipsative vector y, which are difficult to observe directly. A two-stage estimation procedure is suggested for the analysis of structural equation models with OID. In the first stage, the partition maximum likelihood (PML) method and the generalized least squares (GLS) method are proposed for estimating the means and the covariance matrix of Acy, where Ac is a known contrast matrix. Based on the joint asymptotic distribution of the first stage estimator and an appropriate weight matrix, the generalized least squares method is used to estimate the structural parameters in the second stage. A goodness-of-fit statistic is given for testing the hypothesized covariance structure. Simulation results show that the proposed method works properly when a sufficiently large sample is available.This research was supported by National Institute on Drug Abuse Grants DA01070 and DA10017. The authors are indebted to Dr. Lee Cooper, Dr. Eric Holman, Dr. Thomas Wickens for their valuable suggestions on this study, and Dr. Fanny Cheung for allowing us to use her CPAI data set in this article.

This study tests predictions that adolescent psychopaths are hyperresponsive to rewards (Quay, 1988) and deficient in passive avoidance learning (Newman & Kosson, 1986). Forty male adolescent juvenile offenders were divided into psychopaths and nonpsychopaths using cluster analysis. Subjects were administered a passive avoidance learning task which required learning when to respond to cards associated with either reward or punishment. Results showed a greater responsivity to reward in psychopaths, with no group differences in passive avoidance errors. Results lend support to the view that psychopaths tend to focus on the prospect of reward under conditions of mixed incentives and, when sufficiently motivated, are capable of improved performance. Together with findings of recent psychophysiological studies, these results suggest that adolescent psychopaths may have latent abilities which could have treatment implications.The authors are greatly indebted to the boys and staff of the testing institution for their kind cooperation in this study. Thanks are also due to Dr. Rand Wilcox for statistical consultation and Cheryl Eurton and Marni Ayers for assistance in data coding. 相似文献

A comparison of the effects of spatial separation on apparent motion in the auditory and visual modalities 总被引:1,自引:0,他引:1
In the present investigation, the effects of spatial separation on the interstimulus onset intervals (ISOIs) that produce auditory and visual apparent motion were compared. In Experiment 1, subjects were tested on auditory apparent motion. They listened to 50-msec broadband noise pulses that were presented through two speakers separated by one of six different values between 0 degrees and 160 degrees. On each trial, the sounds were temporally separated by 1 of 12 ISOIs from 0 to 500 msec. The subjects were instructed to categorize their perception of the sounds as "single," "simultaneous," "continuous motion," "broken motion," or "succession." They also indicated the proper temporal sequence of each sound pair. In Experiments 2 and 3, subjects were tested on visual apparent motion. Experiment 2 included a range of spatial separations from 6 degrees to 80 degrees; Experiment 3 included separations from .5 degrees to 10 degrees. The same ISOIs were used as in Experiment 1. When the separations were equal, the ISOIs at which auditory apparent motion was perceived were smaller than the values that produced the same experience in vision. Spatial separation affected only visual apparent motion. For separations less than 2 degrees, the ISOIs that produced visual continuous motion were nearly equal to those which produced auditory continuous motion. For larger separations, the ISOIs that produced visual apparent motion increased. 相似文献

Perceived relationships among nine facial expressions were structurally represented in a two-space configuration by multidimensional scaling procedure. The two dimensions operative for Chinese judges were interpreted as positive versus negative emotions and open versus controlled styles of expressions. While there was some consensus in identifying seven of the nine intended emotions, interest-excitement and disgust-revulsion were often not recognized. Implications of cross-cultural comparisons in identification rates were discussed. 相似文献

The research examined perceptions of Chinese immigrants held by New Zealanders of European and Maori descent. The study (N = 318) adopted an intergroup perspective to test a predictive model of attitudes toward immigrants. It was based on a nation‐wide survey with prospective respondents randomly selected from the New Zealand Electoral rolls. Findings revealed that Maori differed from their European counterparts in predictable ways, reporting more relative deprivation and greater perceived threat, and holding more negative outgroup attitudes. Less contact and greater perceived threat predicted more negative attitudes toward immigrants; in addition, when intergroup boundaries were permeable, the link between perceived threat and negative attitudes was stronger in Maori than New Zealand Europeans. While intergroup relations are traditionally analysed in a dual group formation involving a privileged “dominant” ingroup and disadvantaged “minority” immigrant outgroup, the current research suggests the need to advance beyond this dichotomy to a more inclusive approach and to consider the interface between the historical and political milieux in specific national contexts. 相似文献
