There has been much philosophical interest regarding the ‘hierarchy of evidence’ used to determine which study designs are
of most value for reporting on questions of effectiveness, prognosis, and so on. There has been much less philosophical interest
in the choice of outcome measures with which the results of, say, an RCT or a cohort study are presented. In this paper, we
examine the FDA’s recently published guidelines for assessing the psychometric adequacy of patient-reported outcome measures.
We focus on their recommendations for demonstrating content validity and also for how researchers should weigh up the sum
of psychometric evidence when choosing these measures. We argue that questions regarding judgment and understanding meaning
of these measures should play a more central role in determining their adequacy. 相似文献

The affective structure of supportive parenting: depressive symptoms, immediate emotions, and child-oriented motivation 总被引:1,自引:0,他引:1
This study investigated the maternal concerns and emotions that may regulate one form of sensitive parenting, support for children's immediate desires or intentions. While reviewing a videotape of interactions with their 1-year-olds, mothers who varied on depressive symptoms reported concerns and emotions they had during the interaction. Emotions reflected outcomes either to children (child-oriented concerns) or to mothers themselves (parent-oriented concerns). Child-oriented concerns were associated with fewer negative emotions and more supportive behavior. Supportive parenting was high among mothers who experienced high joy and worry and low anger, sadness, and guilt. However, relations depended on whether emotions were child or parent oriented: Supportive behavior occurred more when emotions were child oriented. In addition, as depressive symptoms increased, mothers reported fewer child-oriented concerns, fewer child-oriented positive emotions, and more parent-oriented negative emotions. They also displayed less supportive behavior. Findings suggest that support for children's immediate intentions may be regulated by parents' concerns, immediate emotions, and depressive symptoms. 相似文献

We examined the effects of stimulus (reinforcer) variation in several different contexts. In Study 1, we identified high-quality (HQ) and low-quality (LQ) stimuli based on results of a paired-stimulus assessment and examined their effects when available under concurrent-reinforcement schedules for 8 participants. No participants showed preference for the LQ stimuli when compared singly or in a varied arrangement to the HQ stimulus. In Study 2, we identified nonpreferred (NP) stimuli based on results of a single-stimulus assessment and examined their effects when available under single-reinforcement schedules for 3 participants. Results of Study 2 were mixed. One participant's data indicated that the varied presentation of NP stimuli produced a modest improvement in performance over that observed when the stimuli were presented singly. By contrast, a second participant's data showed no facilitative effect for the varied delivery of NP stimuli and that the inclusion of an HQ stimulus in the varied arrangement obscured the reinforcing effects of the HQ stimulus. The 3rd participant's data showed no effect for the varied delivery of NP stimuli but an apparent facilitative effect when an HQ stimulus was included in the varied arrangement, which was attributable solely to the presence of the HQ stimulus. 相似文献

The present study examined the joint effects of repetition and response deadline on associative recognition in older adults. Young and older adults studied lists of unrelated word pairs, half presented once (weak pairs) and half presented four times (strong pairs). Test lists contained old (intact) pairs, pairs consisting of old words that had been studied with other partners (rearranged lures), and unstudied pairs (new lures), and participants were asked to respond "old" only to intact pairs. In Experiment 1, participants were tested with both short and long deadlines. In Experiment 2, the tests were unpaced. In both experiments, repetition increased hit rates for young and older adults. Young adults tested with a long deadline showed reduced (Experiment 1) or invariant (Experiment 2) false alarms to rearranged lures when word pairs were studied more often. Young adults tested with a short deadline and older adults tested under all conditions had increased false alarm rates forstrong rearranged pairs. Implications of these results for theories of associative recognition and cognitive aging are explored. 相似文献

The present study was conducted to examine hemispheric division of labor in the initial processing and error monitoring in tasks for which hemispheric specialization exists. We used lexical decision as a left hemisphere task and bargraph judgment as a right hemisphere task, and manipulated cognitive load. Participants had to respond to one of two stimuli presented to both visual fields and were instructed to correct their errors. To achieve enough correctable errors, participants were encouraged to respond quickly by using a bonus system. The results showed the classical asymmetry for initial responses in both tasks and reversed asymmetry for corrections in the bargraph task at both load conditions, and in the lexical decision task at the high load condition. The results suggest that each hemisphere monitors the ongoing process in the contralateral one and that the dissociation of initial process and its monitoring grows with load of task. 相似文献

This paper discusses the experience of a Philippines-based agricultural research program, where participatory evaluation is
embedded in a broader, user-centered participatory research approach. Three case projects illustrate and analyze participatory
evaluation of agricultural research in a developing country context. Different evaluation types are identified and their use
in different phases of the research process is discussed. These field experiences show how “evaluation from the inside” can
contribute to effective research planning and implementation, particularly in enhancing sensitivity to user needs and situations.
network for user participatory rootcrop R&D sponsored by the International Potato Center in Asia. Under his leadership, UPWARD
has increasingly sought to build participatory monitoring and evaluation into the network’s research and development activities.
He has a Ph.D. in communication and innovation studies from Wageningen Agricultural University in The Netherlands. Prior joining
UPWARD, Campilan worked with the International Institute of Rural Reconstruction and the Philippine Root Crop Research and
Training Center. His research interests include communication of innovations, institutional linkage development, participatory
research methods and tools, and strengthening local knowledge systems.
From 1991 until 1997 he was coordinator of Users’ Perspectives With Agricultural Research and Development (UPWARD) network.
He was previously based in Latin America. His main research interests include the socioeconomic and cultural aspects of crop
genetic diversity conservation and utilization involving ethnobotanical studies, on-farm conservation, and work on seed systems.
He is also interested in research on rural enterprise development. He has been actively involved in capacity building initiatives

Filicide is defined as the killing of children from birth to age 18 by a natural or step-parent. The legal definition of filicide in Korea does not impose such age limits. Although families in contemporary Korea are nuclear in structure, they were multigenerational prior to the industrialisation that occurred during the second half of the twentieth century. While psychiatric and evolutionary theories have been predominantly used in the filicide literature, prior works have neglected to examine how culture shapes violence against one’s offspring. This paper explores the offence, offender, and victim characteristics in South Korean filicides (1948–1962) through a content analysis of a major newspaper (Chosun Ilbo). Results indicate that filicides occur in one-on-one contexts, primarily carried out by biological parents against their offspring while adoptive children appeared as victims due to the genealogical customs practiced in Korean society. Results indicate that more than 12% of filicide victims are adults. The implications of our findings are discussed. 相似文献
