This study examines the clinical utility of behavior ratings made by nonclinician examiners during assessments of preschool children with Attention-Deficit/Hyperactivity Disorder (AD/HD). Matched samples of children with (n = 127) and without (n = 125) AD/HD were utilized to test the internal, convergent, concurrent, and incremental validity of ratings completed by examiners on the Hillside Behavior Rating Scale (HBRS). Results indicated that HBRS ratings were internally consistent, possessed sufficient interrater reliability, and were significantly associated with parent and teacher reports of AD/HD when controlling for age, gender, intelligence, and symptoms of other psychopathology. HBRS ratings also were significantly associated with other measures of functioning, and provided a significant increment in the prediction of impairment over parent and teacher report alone. These findings suggest that behavioral ratings during testing provide a unique source of clinical information that may be useful as a supplement to parent and teacher reports.  相似文献

Three experiments examined the effect of toxicosis on instrumental responding. These studies were prompted by Morrison and Collyer's (1974, Experiment 1) finding that the induction of toxicosis after an instrumental conditioning session produces greater response suppression if the response is reinforced by a novel saccharin solution rather than familiar water during conditioning. Experiments 1 and 2 investigated whether this suppression was mediated by the Pavlovian contingency between the contextual cues and the saccharin solution or the instrumental relationship between the response and the reward. A role for the instrumental contingency was indicated by the greater suppression of the response producing novel saccharin rather than water when the context of both responses was equally associated with the saccharin and illness. Experiment 3 found that extinction of the aversion to a novel reinforcer following aversive conditioning would re-establish an action previously associated with that reinforcer, in contrast to an action whose reinforcer remained aversive. This result was a further indication that the instrumental contingency between the response and reward contributes to response suppression.  相似文献

Self-determination theory posits 3 basic psychological needs: autonomy (feeling uncoerced in one's actions), competence (feeling capable), and relatedness (feeling connected to others). Optimal well-being results when these needs are satisfied, though this research has traditionally focused on individual well-being outcomes (e.g., E. L. Deci & R. M. Ryan, 2000). Three studies examined the role of need fulfillment in relationship functioning and well-being. Study 1 found that fulfillment of each need individually predicted both individual and relationship well-being, with relatedness being the strongest unique predictor of relationship outcomes. Study 2 found that both partners' need fulfillment uniquely predicted one's own relationship functioning and well-being. Finally, in Study 3, the authors used a diary recording procedure and tested a model in which the association between need fulfillment and relationship quality was mediated by relationship motivation. Those who experienced greater need fulfillment enjoyed better postdisagreement relationship quality primarily because of their tendency to have more intrinsic or autonomous reasons for being in their relationship.  相似文献

Recent research has explored social-interactional factors in the etiology and maintenance of depression. The current investigation further explored the social-interactional model using face-to-face interactions between depressed and nondepressed individuals, as well as the applicability of this model to observed differences in male and female depression. Forty depressed and 40 nondepressed subjects interacted with same or opposite-sex partners. The 20-minute interactions were videotaped and scored with a behavioral coding system. Subjects completed questionnaires concerning perceptions of their partners and the interaction. Results indicated that depressed and non-depressed subjects behaved similarly during the interactions. However, depression was associated with a number of socially unskilled behaviors. Depression in males was related to additional skills deficits not observed for females. While male and female self-report of depression did not differ, males consistently reported greater negative affect. Partner impressions differed based upon sex of partner, and not his or her level of depression. The robustness of the social-interactional model and methodological considerations for future research with this model are discussed.This article is based on the first author's master's thesis conducted under the supervision of the second author who is now at Catholic University. Portions of this research were presented at the 32nd annual meeting of the Southeastern Psychological Association.The authors wish to thank George A. Clum and Thomas H. Ollendick for serving as committee members; Teresa K. Meade for her invaluable help in data collection; and Katie Bechtel, Ruth Townsley, and Mike Cobler for their assistance in scoring and coding data. Thanks also to an anonymous reviewer for helpful comments on an earlier draft of this paper.  相似文献

Two experiments investigated the role of lithium-mediated environmental conditioning on instrumental performance. Experiment 1 demonstrated that a novel taste consumed in one arm of a T maze prior to lithium-induced toxicosis reduced performance in this environment whereas similar aversions conditioned in the home cage failed to alter maze performance. Experiment 2 showed that maze performance in a straight alleyway was decremented during extinction only in a group that actually traversed the alley prior to drinking saccharin and receiving lithium injections. This demonstrated that the instrumental decrement observed in Experiment 1 was due not only to the presence of an unpalatable flavor in the goalbox during the test.

Public health ethics began to emerge in the 1990s as a development within bioethics. Public health ethics education has been implemented in schools of public health in recent years, and specific professionalism and ethics competencies were included in the Master of Public Health (MPH) competency set developed nationally and adapted by individual schools of public health around the country. The University of Texas School of Public Health approved the present set of MPH competencies in 2005. After 4 years of experience, we now report information measuring the extent to which “Professionalism and Ethics” competencies and subcompetencies are being met in the MPH degree program. To this end we have audited the MPH “Professionalism and Ethics” competency forms for FY2009 MPH graduates (n = 61). Eight courses, including required MPH core courses plus the practicum and culminating experience, were found to have substantial professionalism and ethics content. Further, 67.2% of graduates met eight or more of the 13 competencies and subcompetencies, but only 36.1% met all thirteen, indicating a need to identify topic areas to be added to, or enhanced in, the MPH curriculum. In addition, these findings will inform ongoing efforts to enhance ethics education in our health science center. Assessment of these competencies and subcompetencies is an essential step in strengthening ethics education at our institutions and in better preparing our graduates for a challenging future. We report our efforts here to demonstrate one way of carrying out programmatic assessment of ethics education in a school of public health.  相似文献
