Method: Sixty English-speaking children, 7-14 years old with normal hearing, had a single study visit during which each test was administered twice. Changes on retest were summarized by within-subject standard deviation ( S[subscript w]), compared among tests, and compared with binomial model predictions. Correlates of variance were explored.…

This note confronts the common use of a single coefficient alpha as an index informing about reliability of a multicomponent measurement instrument in a heterogeneous population. Two or more alpha coefficients could instead be meaningfully associated with a given instrument in finite mixture settings, and this may be increasingly more likely the…

Knee flexor and extensor muscular assessment via isokinetic dynamometry is common practice and established in the research literature. However, reporting assessment methodology regarding reciprocal and nonreciprocal movements is often vague or absent. Such methodological issues are crucial for accurate assessments. Therefore, knee extensor and…

This note discusses the merits of coefficient alpha and their conditions in light of recent critical publications that miss out on significant research findings over the past several decades. That earlier research has demonstrated the empirical relevance and utility of coefficient alpha under certain empirical circumstances. The article highlights…

Reliability is the consistency of a set of scores that are designed to measure the same thing. Reliability is a statistical property of scores that must be demonstrated rather than assumed.

The literature was screened during the development of the scale, the opinions of the teaching staff about the subject were…

There is a need for cancer-specific tools to evaluate loneliness and cancer-related negative social expectations before developing interventions for cancer patients. The purpose of this study was to examine the reliability and validity of the Cancer Loneliness and the Cancer-related Negative Social Expectations Scale. Data were collected from 300…

What follows is a practical guide for establishing the validity of a survey for research purposes. The motivation for providing this guide is our observation that researchers, not necessarily being survey researchers per se, but wanting to use a survey method, lack a concise resource on validity. There is far more to know about surveys and survey…

Being a significant dimension in affective behavior education, values are guiding concepts for explaining the cognitive and social structures. In the process of value acquisition, the tendency of individuals for the value being targeted for acquisition bears a great significance. In the present study, the main aim is to develop an assessment…
