Composite Reliability = (Sum of standardized loadings. Reliability comes to the forefront when variables developed from summated scales are used as predictor components in objective models.

Test-retest reliability Test-retest reliability is used as an indicator of the stability of scores on an instrument over time (Kubiszyn & Borich, ). Cronbach’s alpha is a statistic commonly quoted by authors to demonstrate that tests and scales that have been constructed or adopted for research projects are fit for purpose.

Cronbach’s alpha is regularly adopted in studies in science education: it was referred to in 69 different papers published in 4 leading science education journals in a single year ()—usually as a measure of   reliability.

Another way to look at reliability is to say that two people who are the same in terms of the construct being measured, should get the same score. In statistical terms, the usual way to look at reliability is based on the idea that individual items (or sets of items) should produce results consistent with the overall Composite reliability is based on the factor loadings in a confirmatory factor analysis (CFA).

In the case of a unidimensional scale (like extraversion here), we define a one-factor CFA, and then use the factor loadings to compute our internal consistency estimate. I won’t go into the detail, but we can interpret a composite reliability score   composite reliability measure.

Finn, Sawyer, and Behnke () also used the Mosier composite reliability coeffi-cient to estimate the reliability of the Psychological State Anxiety Scale. Based on these studies, multidimensional re-liability testing can clearly be employed for assessments of a broad range of psychological attributes 21 no 2 /Wahyu Widhiarso The most commonly applied estimate of a composite scales reliability is a from RESEARCH at Yarmouk University Reliability Based Aircraft Maintenance Optimization and Applications presents flexible and cost-effective maintenance schedules for aircraft structures, particular in composite airframes.

Every metric or method we use, including things like methods for uncovering usability problems in an interface and expert judgment, must be assessed for reliability.

In fact, before you can establish validity, you need to establish reliability.
