Significant discrepancies have been found between interview- and questionnaire-based assessments of psychopathology; however, these studies have typically compared instruments with unmatched item content. The Eating Disorder Examination (EDE), a structured interview, and the questionnaire version of the EDE (EDE–Q) are considered the preeminent assessments of eating disorder symptoms and provide a unique opportunity to examine the concordance of interview- and questionnaire-based instruments with matched item content. The convergence of EDE and EDE–Q scores has been examined previously; however, past studies have been limited by small sample sizes and have not compared the convergence of scores across diagnostic groups. A meta-analysis of 16 studies was conducted to compare the convergence of EDE and EDE–Q scores across studies and diagnostic groups. With regard to the EDE and EDE–Q subscale scores, the overall correlation coefficient effect sizes ranged from .68 to .76. The overall Cohen's d effect sizes ranged from .31 to .62, with participants consistently scoring higher on the questionnaire. For the items measuring behavior frequency, the overall correlation coefficient effect sizes ranged from .37 to .55 for binge eating and .90 to .92 for compensatory behaviors. The overall Cohen's d effect sizes ranged from ?0.16 to ?0.22, with participants reporting more binge eating on the interview than in the questionnaire in 70% of the studies. These results suggest the interview and questionnaire assess similar constructs but should not be used interchangeably. Additional research is needed to examine the inconsistencies between binge frequency scores on the 2 instruments. (PsycINFO Database Record (c) 2011 APA, all rights reserved) 相似文献

A novel, low-cost implementation of “democratic”load-current sharing of paralleled converter modules
A simple, low-cost, and robust “democratic” (autonomous) current-sharing (CS) circuit is proposed and analyzed. The circuit maintains good CS among the modules by properly adjusting the voltage references of the modules based on the differences between the average current of the paralleled modules and the currents of the individual modules. Design guidelines for achieving a desired CS performance are given and verified on a number of DC/DC modules operating in parallel 相似文献

The Ca3Ru2O7 with a Mott-like transition at 48 K and a Neel temperature at 56 K features different in-plane anisotropies of magnetization
and magnetoresistance. Applying the magnetic field along the magnetic easy axis precipitates a spin-polarized state via a
first-order metamagnetic transition but does not lead to full suppression of the Mott state, whereas applying a magnetic field
along the magnetic hard axis does, causing a resistivity reduction of three orders of magnitude. The colossal magnetoresistivity
is attributed to the collapse of a novel, orbitally ordered and spin-polarized state. This new phenomenon is striking in that
the spin polarization, which is a fundamental driving force for all other magnetoresistive systems, is detrimental to the
colossal magnetoresistance (CMR) in this 4d-based electron system. Evidence for a density wave is also presented. 相似文献

OBJECTIVE: To find out how physicians would manage thrombotic complications in patients with primary intracerebral haemorrhage. DESIGN: Fifty-six participants at a British Geriatrics Society session on stroke were asked to state on a self-completion question sheet how they would manage two hypothetical cases. RESULTS: There was support for a wide range of treatments but no consensus on how to treat patients with life-threatening thrombosis after cerebral haemorrhage. 相似文献

A simple cytotoxicity assay for Listeria species was developed by assaying alkaline phosphatase (AP) release from an infected hybrid B lymphocyte (Ped-2E9) line. Eight of eight L. monocytogenes and six of 11 L. ivanovii strains induced significantly high AP release from Ped-2E9 cells compared to five other L. ivanovii strains and other Listeria spp. In contrast, all L. monocytogenes and L. ivanovii test strains showed high release of lactate dehydrogenase (LDH) activity from Ped-2E9 cells. The molecular mass of AP was estimated to be about 128-165 kDa, suggesting severe membrane damage in Ped-2E9 cells due to Listeria infection. The data presented here indicate that AP assay could be used over LDH assay to detect Listeria-induced cell cytotoxicity. 相似文献
