The criterion validity of the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD; Zanarini et al., Journal
of Personality Disorders 17:568–573, 2003) as a quick screening device for borderline personality disorder (BPD) was evaluated alongside the more established Personality
Diagnostic Questionnaire-4+ Borderline subscale (PDQ-BPD; Hyler 1994) using receiver operator characteristic (ROC) analysis. Both instruments demonstrated adequate criterion validity with the
diagnosis of BPD derived from a clinician-administered diagnostic interview. Optimal cutoffs for each measure were determined
using sensitivity, specificity, and positive and negative likelihood ratios. The previously established cutoff for the MSI-BPD
of seven (Zanarini et al., Journal of Personality Disorders 17:568–573, 2003) was confirmed. The current study provides the first support for the use of the MSI-BPD as a screening measure for use in
community-based studies of BPD. 相似文献

With a growing body of literature linking systems of high-performance work practices to organizational performance outcomes, recent research has pushed for examinations of the underlying mechanisms that enable this connection. In this study, based on a large sample of Welsh public-sector employees, we explored the role of several individual-level attitudinal factors--job satisfaction, organizational commitment, and psychological empowerment--as well as organizational citizenship behaviors that have the potential to provide insights into how human resource systems influence the performance of organizational units. The results support a unit-level path model, such that department-level, high-performance work system utilization is associated with enhanced levels of job satisfaction, organizational commitment, and psychological empowerment. In turn, these attitudinal variables were found to be positively linked to enhanced organizational citizenship behaviors, which are further related to a second-order construct measuring departmental performance. 相似文献

Little is known about the characteristics of meals that serve as motivating operations (MOs) for escape behavior. In the current investigation, we showed that the distance at which a therapist held a spoon from a child's lips served as an MO for escape behavior. Based on these results, we implemented spoon distance fading, compared fading with and without escape extinction (EE), and compared fading plus EE to EE alone. Initially, inappropriate mealtime behavior decreased during fading, but this effect was not maintained as fading progressed. Inappropriate mealtime behavior was lower initially when we combined fading and EE relative to EE alone, but acceptance increased more rapidly with EE than with fading plus EE. These results suggest that a number of mealtime characteristics might function as MOs for escape behavior and that analyses of MOs may be useful for developing treatments for food refusal. 相似文献

This study examined packing (pocketing or holding accepted food in the mouth) in 3 children who were failing to thrive or had inadequate weight gain due to insufficient caloric intake. The results of an analysis of texture indicated that total grams consumed were higher when lower textured foods were presented than when higher textured foods were presented. The gram intake was related directly to levels of packing. That is, high levels of packing were associated with higher textured foods and low gram intake, and low levels of packing were associated with lower textured foods and high gram intake. All participants gained weight when texture of foods was decreased. Packing remained low during follow-up for 2 participants even when the texture of food was increased gradually over time. These data are discussed in relation to avoidance, response effort, and skill deficit. 相似文献

A treatment with differential or noncontingent reinforcement and nonremoval of the spoon increased the acceptance of one or two of 16 foods for 2 participants with severe food refusal. These differential levels of acceptance were demonstrated empirically in an ABAB design in which A was the presentation of the accepted (preferred) foods and B was the presentation of foods the participants refused (nonpreferred foods). Subsequently, we implemented a blending treatment that consisted of mixing (blending) nonpreferred foods into preferred foods in various ratios (e.g., 10% nonpreferred/90% preferred, 20% nonpreferred/80% preferred). We then presented nonpreferred foods that had been exposed to blending to determine if consumption of nonpreferred foods would increase following the blending treatment. We also conducted periodic reversals in which we presented nonpreferred foods that had not been exposed to the blending treatment. Following initial implementation of the blending treatment, consumption was high for nonpreferred foods that had been blended and low for nonpreferred foods that had not been blended. Consumption increased for all foods (i.e., foods that had been exposed to blending and foods that had not been exposed to blending) after seven or eight foods had been exposed to the blending treatment. Thus, the variety of foods consumed by the participants increased from one or two to 16. These results are discussed in terms of stimulus fading, conditioned food preferences, and escape extinction.

Semantic processing errors are symptoms of an up-regulation (schizophrenia) or degradation (Parkinsonism) of dopaminergic pathways. A recent connectionist model attributed errors in the schizophrenic processing of context to increased gain in competitive neural processes. This study extends this "gain hypothesis" by comparing the sensitivity to reduced gain of a simulation of semantic route activation to characteristic semantic judgment errors made by Parkinson's patients in an open search task. Under normal gain conditions, the dominant sense of polysemous words "wins" through competition and lateral inhibition at the word sense level (beta(inh)). For words with very different sense frequencies, decreasing gain by increasing beta(inh) resulted in the dominant word sense winning; however, for words with similar sense frequencies, increasing beta(inh) resulted in the dominant word sense winning only for low to moderate values. At high levels, no clear winner emerged after 200 epochs, with the least dominant sense reaching the maximum activation value. These results are discussed in the context of the Yerkes-Dodson Law, which may provide a theoretical basis for understanding normal and impaired semantic performance in catecholaminergic disorders. 相似文献

Musicologists and linguists have often suggested that the prosody of a culture's spoken language can influence the structure of its instrumental music. However, empirical data supporting this idea have been lacking. This has been partly due to the difficulty of developing and applying comparable quantitative measures to melody and rhythm in speech and music. This study uses a recently-developed measure for the study of speech rhythm to compare rhythmic patterns in English and French language and classical music. We find that English and French musical themes are significantly different in this measure of rhythm, which also differentiates the rhythm of spoken English and French. Thus, there is an empirical basis for the claim that spoken prosody leaves an imprint on the music of a culture. 相似文献

How experts' adaptations to representative task demands account for the expertise effect in memory recall: comment on Vicente and Wang (1998) 总被引:1,自引:0,他引:1
K. A. Ericsson and W. Kintsch's (1995) theoretical framework of long-term working memory (LTWM) accounts for how experts acquire encoding and retrieval mechanisms to adapt to real-time demands of working memory during representative interactions with their natural environments. The transfer of the same LTWM mechanisms is shown to account for the expertise effect in unrepresentative "contrived" memory tests. Therefore, K. J. Vicente and J. H. Wang's (1998) critique of the generalizability of the LTWM framework is rejected. Their proposed refutation of LTWM accounts is found to be based on misrepresented facts. The process-based framework of LTWM is shown to be superior to their product theory because it can explain interactions of the expertise effect in "contrived" recall under several testing conditions differing in presentation rate, instructions, and memory procedures. 相似文献

The development of more effective and less costly family- and community-based services to serve as alternatives to out-of-home placements of children is an important priority in the reform of mental health services for children and adolescents. Within the context of a randomized trial with 118 substance abusing or dependent juvenile offenders, we examined the incremental costs of multisystemic therapy (MST) and related these costs to observed reductions in days of incarceration, hospitalization, and residential treatment at approximately 1 year postreferral. Results showed that the incremental costs of MST were nearly offset by the savings incurred as a result of reductions in days of out-of-home placement during the year.
