Reliability and Validity of the Severity of Illness Index
Medical Care, 1986The authors discuss the objectives and definition of the Severity of Illness Index, which has been developed and refined at The Johns Hopkins University over the past 5 years. In addition, the training program for raters, the method used to ascertain reliability, and data from reliability testing in 18 hospitals are described.

Reliability index in geotechnics
Computers and Geotechnics, 1985Abstract In this paper, the reliability index β is examined for its applicability in geotechnics. A statistical finite difference scheme is proposed to evaluate partial derivatives of the limit state function, enabling the computation of the reliability index β.

Reliability of self-reporting of antibiotic consumption in the community - Index of Reliability
Journal of Clinical Pharmacy and Therapeutics, 2014To date, there is no evidence to indicate the reliability of how patients self-report their own antibiotic usage in the community. Such data are fundamental in supporting antimicrobial stewardship practices, and so there is a need to determine its accuracy and reliability.Patients in the community (n = 476) were required to recollect their antibiotic ...

A procedure for evaluating the reliability of a gingivitis index
Journal of Clinical Periodontology, 1986Abstract A methodology is presented for assessing the reliability of an ordinally‐scaled index and is illustrated by using data from a clinical trial in which gingival inflammation was assessed with the PMGI index, independently, by 5 examiners. One of the examiners was an experienced examiner, the others newly trained.

Reliability of the periapical index scoring system
European Journal of Oral Sciences, 1988Abstract — Data accumulated in one methodological and two longitudinal clinical studies employing the periapical index (PAI) scoring system were analyzed to assess the usefulness and reliability of the PAI system. More than 93% of pairs of PAI scores were either identical or deviated from each other with one step only for intra‐ and interexaminer ...

Uncertain reliability index in finite element reliability analysis
International Journal of Reliability and Safety, 2006Finite Element Reliability Analysis (FERA) has been devised to obtain the probability of structural response events based on random material, geometry and loading parameters. Previously, such analysis has not distinguished between the uncertainties arising from inherent randomness, and from model errors and insufficient knowledge about the probability ...

Reliability of the craniomandibular index.
Journal of orofacial pain, 2003To examine various dimensions of reliability of the Craniomandibular Index, a commonly used instrument for quantifying the severity of signs and symptoms of temporomandibular disorders.Classical psychometric theory and generalizability theory were used to assess the reliability of data obtained from a calibration study of examiners participating in a ...

THE LIFE REGARD INDEX: RELIABILITY AND VALIDITY
Psychological Reports, 1990This study investigated the reliability and factorial validity of the Life Regard Index, a measure of meaning in life. Principal component factor analyses performed on the responses of 122 undergraduate psychology students, gave two factors, fulfillment and framework, confirming the theoretical structure.

Reliable Indexing Using Unreliable Recognition Devices
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1981A new method is described and tested for using an unreliable character recognition device to produce a reliable index for a collection of documents. All highly likely substitution errors of the recognition device are handled by transforming characters which confuse readily into the same pseudocharacter.
