Measurement criteria: err on the side of establishing higher degree of precision in measurement, err on the side of accuracy, even if that means having less precise measures (do not measure. Establishing reliable measures: variety of different approaches, inter-rater reliability, test-retest reliability, parallel-forms reliability, split-half reliability. Establishing validity: different types of validity, face validity, content validity, criterion-related validity.
