Rationale 1: Face validity is an estimation of validity based on a preliminary examination to see if it measures the concept.
Rationale 2: Construct validity refers to the degree an instrument measures the construct it is supposed to measure.
Rationale 3: Content validity for an instrument is concerned with the scope or range of items used to measure the variable. Content validity can be determined by a panel of experts.
Rationale 4: Criterion validity compares the instrument's ability to measure subjects' behavior with some other criterion (measure) of that same behavior.
