A breakdown of reliability coefficients by test type and reliability method, and the clinical implications of low reliability.


The author presented descriptive statistics for 937 reliability coefficients for various reliability methods (e.g., alpha) and test types (e.g., intelligence). He compared the average reliability coefficients with the reliability standards that are suggested by experts and found that most average reliabilities were less than ideal. Correlations showed that… (More)
