WebSep 7, 2024 · Internal Consistency Reliability Defined Internal consistency is a method of reliability in which we judge how well the items on a test that are proposed to measure the same construct produce... WebCronbach’s alpha (Cronbach, 1951), also known as coefficient alpha, is a measure of reliability, specifically internal consistency reliability or item interrelatedness, of a scale or test (e.g., questionnaire). Internal consistency refers to the extent that all items on a scale or test contribute positively towards measuring the same construct.
