PURPOSE The aim of this study was to characterize differences in health-related quality of life among women presenting for treatment of fecal incontinence. METHODS Among 155 women presenting for treatment of fecal incontinence in a specialty clinic, validated questionnaires measured impact on quality of life (Modified Manchester Health Questionnaire) and severity (the Fecal Incontinence Sever...

background: given the lack of consistency in the literature regarding the reliability of the ankle-brachial index (abi) as a valid screening tool and an independent risk indicator of cardiovascular events and mortality, we compared it with angiography as a reference standard test. methods: this case-control study, conducted between 2010 and 2011 in tehran heart center, recruited 362 angiographi...

Cronbach's a is the most widely used index of the reliability of a scale. However, its use and interpretation can be subject to a number of errors. This article discusses the historical development of a from other indexes of internal consistency (split-half reliability and Kuder-Richardson 20) and discusses four myths associated with a: (a) that it is a fixed property of the scale, (b) that it ...

In [13] co graphs are introduced and a formula is given for the PI index of these graphs. Based on this formula a new topological CI index is proposed. In this note it is observed that co graphs are precisely isometric subgraphs of hypercubes alias partial cubes. Some fact about partial cubes and their uses in chemical graph theory are listed. A couple of comments on the CI index are also given...

INTRODUCTION The AD8 is a brief informant-based questionnaire that may also be self-administered, and which aids in identifying cognitive impairment (CI). Our goal is to assess the diagnostic accuracy (DA) of a Spanish version of that questionnaire. MATERIAL AND METHODS Cross-sectional study of a clinical sample of patient/informant dyads including 330 subjects with suspected CI or dementia (...

Interval pairwise comparison matrices are widely accepted for practical decision making problems when the maker is unable to provide an exact judgment on alternatives. However, as measuring preference consistencies in important, this paper proposes a new interval matrix consistency measure, average geometric index, that assumes given follows lognormal distribution. This measure accounts boundar...
