First, you cannot have a valid instrument unless the instrument is reliable. Validity reflects the extent to which any measuring instrument measures what it is designed to measure. Validation refers to the inferences made based on scores obtained on a measure. We validate not the measuring instrument itself but the measuring instrument in relation to the purpose for which it is being used.
