The purpose of this investigation was to assess the reliability and validity of eight developmental asset measures among a stratified, random sample (N = 540) of college students to guide health promotion efforts. The sample was randomly split to produce exploratory and confirmatory samples for factor analysis using principal axis factoring and varimax rotation and structural equation modeling techniques. Items were retained on factors if they had high loadings greater than .40 and were not complex. Concurrent validity was examined among substance use (including alcohol and tobacco) and sexual risk-taking variables. Exploratory and confirmatory samples did not differ on demographics. Parallel analysis confirmed the eight theorized constructs. Exploratory factor loadings were greater than .40. Concurrently, validity analyses were in the predicted direction. Cronbach alphas were .70 or greater with the exception of the Future Aspirations asset. Preliminary analyses support the reliability and validity of measuring developmental assets among emerging adults. Implications and potential uses are discussed.  相似文献

Although formal ethics classes provide a basic foundation in managing ethical dilemmas, professionals often point to their experiences on internship as an important training ground for consolidation of their ethical development. Clinical interns face many personal and professional transitions that can lead to a number of ethical dilemmas. Effective collaboration between administrative staff, supervisors, and interns can create a pragmatic model for negotiating these dilemmas. In this paper, issues related to balancing intern competency with training and patient/client needs, managing dual relationships with supervisory staff, and dealing with differences in orientation are addressed from the perspective of both the site and the intern. We also discuss ways in which problems can arise and how both sides can work together systematically to negotiate those problems. To illustrate this process, we discuss cases involving effective collaboration between interns and sites. Finally, the authors assert the need for formal, empirically supported training in classic ethical issues, but also in contemporary ethical issues arising from the ever-evolving field of mental health service delivery and unique challenges accompanying these advances.  相似文献

The aim of the current study was to evaluate the services offered by Action for ME to sufferers of Chronic Fatigue Syndrome using measures developed and validated in previous research. Preliminary studies had suggested that clients attending rehabilitation residential courses were benefiting from the service. A further, more in‐depth evaluation process with a greater number of health‐related outcome measures was warranted. In addition, assessment was widened to include other services offered to sufferers of the illness. Data relating to the usefulness and success of the services (rated by the clients) were also collected. Data from client volunteers were collected at baseline (that is, before intervention) and approximately six months later. Quantitative comparative analyses were conducted using within‐group comparisons to assess any improvements in scores at six‐month follow‐up from baseline. Fifty‐six participants completed wide‐ranging questionnaires assessing illness history, psychopathology, psychosocial factors and health and well‐being. Data relating to improvements in illness status and acceptability of treatment were also collected by means of global outcome measures. Both the counselling and residential groups showed improvements in many areas assessed at follow‐up. Most importantly, improvements were indicated in areas such as fatigue and the levels of disability suffered by patients. In addition, there were significant improvements in ratings of mood, anxiety, depression and physical symptoms. Overall, clients reported satisfaction with the care received and most found the services useful. All of the participants who completed the evaluation stated that they would recommend Action for ME services to fellow sufferers. The outcome of the current study is encouraging. The data presented provides evidence of the high level of support and advice Action for ME offers to sufferers of this illness. Furthermore, measurable improvements in scores relating to illness status were accompanied by improvements in mental health and psychosocial variables in the patient group.  相似文献

The Cognitive Reflection Test (CRT) is among the most common and well-known instruments for measuring the propensity to engage reflective processing, in the context of the dual-process theory of high-level cognition. There is robust evidence that men perform better than women on this test—but we should be wary to conclude that men are more likely to engage in reflective processing than women. We consider several possible loci for the gender difference in CRT performance, and use mathematical modeling to show, across two studies, that the gender difference in CRT performance is more likely due to women making more mathematical mistakes (partially explained by their greater mathematics anxiety) than due to women being less likely to engage reflective processing. As a result, we argue that we need to use gender-equivalent variants of the CRT, both to improve the quality of our instruments and to fulfill our social responsibility as scientists.  相似文献

Forty-six parent-referred problem 3-year-olds and 22 comparison children were assessed with parent report and observational measures; 54 were followed up at age 4, and 53 were followed again at age 6. Lower social class and greater family stress were associated with higher symptom ratings at initial referral and age 6 follow-up. Negative and directive maternal behavior and negative and noncompliant child behavior observed in the lab at age 3 were associated with higher maternal ratings of child aggression and hyperactivity; these observed behaviors continued to be highly predictive of maternal ratings of persistent problems at ages 4 and 6. A laboratory index of inattention and overactivity at intake also predicted hyperactivity ratings at age 6. These findings suggest that externalizing problems identified in early childhood are likely to persist when they are associated with more family disruption and a negative mother-child relationship.This research was supported by Grant No. MH 32735 from the National Institute of Mental Health to Dr. Campbell. We are indebted to the children and families who have participated so enthusiastically in this study over the past 5 years. The help of Deborah Baldwin, Patricia Cluss, and Diane Gluck is gratefully acknowledged. Many additional people participated in various phases of this study as independent observers and data coders. Their contributions are also recognized.  相似文献

Whether the perception of vowels takes place in the right or left cerebral hemisphere, or is dependent on bilateral cortical processes, is of importance in our treatment of patients with language deficiencies. To investigate this problem a phonetic test with a series of vowellike stimuli was administered to 68 right-handed adult patients with cerebral lesions, mainly of vascular origin. The results were compared to the results in a control group of 19 speech therapists. Second, a neuroradiologic method was developed in order to visualize the anatomic site of Wernicke's area in the left hemisphere on CT scans. This method formed the basis for an evaluation of the extent and localization of the patients' lesions in Wernicke's area. Of 46 patients with lesions in the left hemisphere, 19 had no perceptual disturbances and 27 had severe perceptual disturbances with lesions predominantly located in Wernicke's area. Twenty-two patients with lesions in the corresponding area in the right hemisphere showed no perceptual disturbances. The results of this investigation appear to indicate that the perception of vowels in right-handed persons is unilaterally located in Wernicke's area in the left hemisphere.  相似文献
