Composite measures play an important role in psychology and related disciplines. Composite measures almost always have error. Correspondingly, it is important to understand the reliability of the scores from any particular composite measure. However, the point estimates of the reliability of composite measures are fallible and thus all such point estimates should be accompanied by a confidence ...

With short production development times, there is an increased need to demonstrate product reliability relatively quickly with minimal testing. In such cases there may be few if any observed failures. Thus it may be difficult to assess reliability using the traditional reliability test plans that measure only time (or cycles) to failure. For many components, degradation measures will contain im...

Coefficients that assess the reliability of data making processes – coding text, transcribing interviews, or categorizing observations into analyzable terms – are mostly conceptualized in terms of the agreement a set of coders, observers, judges, or measuring instruments exhibit. When variation is low, reliability coefficients reveal their dependency on an often neglected phenomenon, the amount...

CONTEXT Functional strength measures correlate more closely with functional performance than non-functional strength measures. OBJECTIVES To determine the reliability of the lateral step test as a measure of maximal strength. DESIGN Intertester repeated measures. SETTING Research laboratory. PARTICIPANTS Twenty four healthy, pain free subjects. INTERVENTION Two protocols (A and B) wer...

BACKGROUND Scientists and practitioners alike need reliable, valid measures of contextual factors that influence implementation. Yet, few existing measures demonstrate reliability or validity. To meet this need, we developed and assessed the psychometric properties of measures of several constructs within the Inner Setting domain of the Consolidated Framework for Implementation Research (CFIR)....

compared to industrial companies, we have neither enough related literature nor available researches concerning the issue of evaluating the supply chain management as well as supply chain performance. therefore, the current article aims to identify and prioritize measures of evaluating the performance of services supply chain. thus, we first review the related text and define the processes of s...

The reliability of surface electromyographic (sEMG) variables during swallowing determines the potential usefulness of these measures in swallowing assessment and treatment. This study aimed to establish the reliability of the sEMG measures of the swallowing function of muscles during different swallowing conditions in healthy young and old volunteers. Two groups of volunteers (24 older adults,...

BACKGROUND The choice of measure for use as a primary outcome in geriatric research is contingent upon the construct of interest and evidence for its psychometric properties. The Late-Life Function and Disability Instrument (LLFDI) has been widely used to assess functional limitations and disability in studies with older adults. The primary aim of this systematic review was to evaluate the curr...

BACKGROUND The Effective Musculoskeletal Consumer Scale (EC-17) is a self-administered questionnaire for evaluating self-management interventions that empower and educate people with rheumatic conditions. The aim of the study was to translate and evaluate the Norwegian version of EC-17 against the necessary criteria for a patient-reported outcome measure, including responsiveness to change. M...
