The evidence-base services literature is continually growing, providing the field with rich and important sets of information regarding what works for treating different types of youth and families. Given this burgeoning of information, the PracticeWise Evidence-Based Services (PWEBS) Literature Database has been developed to aid in summarizing and delivering aggregated evidence-based treatment information to providers in the field. Meanwhile, the Child and Adolescent Needs and Strengths-Mental Health (CANS-MH) Scale is a youth mental health assessment tool that was developed by a separate team to assist with treatment planning. In the present study, we developed and tested a system for linking these two related ontological systems so that scientific knowledge can be more widely aggregated and made available to a wider set of audiences for enhanced mental health service delivery. Results revealed the following. First, a construct mapping comparison revealed that the CANS-MH and PWEBS ontologies share a strong core of overlapping content, particularly in the areas of Youth Behavioral/Emotional Needs, Youth Risk Behaviors, and Life Domain Functioning. Second, the CANS-MH areas were able to be used to reliably code the following components of published randomized treatment studies: (a) population sample characteristics (e.g., did the characteristics of the treatment study participant population relate to each CANS-MH area?), and (b) outcome measure targets (e.g., did the treatment study outcome measure target areas relate to each CANS-MH area?). The reliability achieved from this coding process supported the linkage between the CANS-MH areas and the PWEBS Literature Database information. Lastly, high agreement was achieved between an automated translation algorithm and the final ratings from the manual coding of published treatment studies using the CANS-MH scale. The importance of such linkages for the communication of ideas, information, and evidence across differing subfields is discussed, as well as examples of achieving enhanced quality of mental health services by linking system ontologies.  相似文献

Target prevalence influences visual search behavior. At low target prevalence, miss rates are high and false alarms are low, while the opposite is true at high prevalence. Several models of search aim to describe search behavior, one of which has been specifically intended to model search at varying prevalence levels. The multiple decision model (Wolfe & Van Wert, Current Biology, 20(2), 121-–124, 2010) posits that all searches that end before the observer detects a target result in a target-absent response. However, researchers have found very high false alarms in high-prevalence searches, suggesting that prevalence rates may be used as a source of information to make “educated guesses” after search termination. Here, we further examine the ability for prevalence level and knowledge gained during visual search to influence guessing rates. We manipulate target prevalence and the amount of information that an observer accumulates about a search display prior to making a response to test if these sources of evidence are used to inform target present guess rates. We find that observers use both information about target prevalence rates and information about the proportion of the array inspected prior to making a response allowing them to make an informed and statistically driven guess about the target’s presence.  相似文献

How do we select behaviourally important information from cluttered visual environments? Previous research has shown that both top-down, goal-driven factors and bottom-up, stimulus-driven factors determine which stimuli are selected. However, it is still debated when top-down processes modulate visual selection. According to a feedforward account, top-down processes modulate visual processing even before the appearance of any stimuli, whereas others claim that top-down processes modulate visual selection only at a late stage, via feedback processing. In line with such a dual stage account, some studies found that eye movements to an irrelevant onset distractor are not modulated by its similarity to the target stimulus, especially when eye movements are launched early (within 150-ms post stimulus onset). However, in these studies the target transiently changed colour due to a colour after-effect that occurred during premasking, and the time course analyses were incomplete. The present study tested the feedforward account against the dual stage account in two eye tracking experiments, with and without colour after-effects (Exp. 1), as well when the target colour varied randomly and observers were informed of the target colour with a word cue (Exp. 2). The results showed that top-down processes modulated the earliest eye movements to the onset distractors (<150-ms latencies), without incurring any costs for selection of target matching distractors. These results unambiguously support a feedforward account of top-down modulation.  相似文献

Reviews school psychologists' services in special education programs. Fifty-eight credentialed school psychologists in 10 school districts were interviewed individually about background and training, professional duties, favored clinical techniques, and opinions and recommendations for improved services. According to self-reports, the bulk of time was devoted to activities directly related to assessment of pupils with little involvement in research, in-service training, or other clinical activities. Professional association memberships were primarily local. Assessment techniques tended to be limited to a few standardized tests. Overall findings support sample psychologists' expressed concerns as to need for changes in preservice and in-service training.  相似文献

The introduction to the EJSP special issue brings together recent literature on allyship. We present and discuss different definitions of allyship and highlight a multiple perspectives approach to understanding the predictors and consequences of allyship. This approach suggests that engagement in allyship can be driven by egalitarian and non-egalitarian motivations and that the behaviours identified as allyship can have different meanings, causes and consequences depending on whether researchers take into account the allies’ perspective or the disadvantaged groups’ perspective. We use this approach as an organizing principle to identify themes that emerge in the papers included in this special issue. We start with four papers that consider the perspective of the advantaged group, followed by two papers that consider the perspective of the disadvantaged group. Finally, we introduce two theoretical papers that examine the relations between disadvantaged groups and allies, and we set out directions for future research.  相似文献

Three studies were conducted to evaluate the influence of environmental context and UCS preexposure intensity on the acquisition of a flavor aversion. In the first study, rats were exposed to two UCS-alone presentations at one of three dose levels of LiCl. The rats were given the two UCS preexposures in one of two contexts (familiar or novel). Following the UCS-alone treatment, all of the subjects received two pairings of sucrose and LiCl (1.25 meq) in the familiar context. Animals receiving UCS preexposures in the same context as used during conditioning consumed significantly more sucrose than did saline control animals. In contrast, the influence of prior UCS preexposure was not evident when UCS preexposure was experienced in a context different from that experienced during conditioning. In Experiment 2, all animal received UCS preexposure and conditioning in the novel room. Animals received either two or four preexposures at 0, 1.25, or 3.75 meq dose of LiCl. Two UCS preexposures at 3.75 meq dose produced a stronger UCS preexposure effect than did the 1.25 meq dose. Animals in Experiment 3 received two exposures to either 0-, 1.25-, or 3.75-meq LiCl in one of two contexts, followed by conditioning with the 1.25-meq LiCl dose in the same context as preexposure. Greater UCS interference occurred in animals preexposed to LiCl in the novel rather than familiar environment, with no specific dose effects in either context. These observations are discussed in terms of context blocking and generalization decrement models of the UCS preexposure effect.  相似文献

In this article, the authors describe the refinement and preliminary evaluation of the Dimensions of Change in Therapeutic Community Treatment Instrument (DCI), a measure of treatment process. In Study 1, a 99-item DCI, administered to a cross-sectional sample of substance abuse clients (N = 990), was shortened to 54 items on the basis of results from confirmatory factor analyses and item response theory invariance tests. In Study 2, confirmatory factor analyses of the 54-item DCI, completed by a longitudinal cohort of 993 clients, established and validated an 8-factor solution across 2 subpopulations (adults and adolescents) and 2 time points (treatment entry and 30-days postentry). The results of the 2 studies are encouraging and support use of the 54-item DCI as a tool to measure treatment process.  相似文献
