The purposes of this study were (a) to introduce new concept of validity and (b) to suggest some guidelines so that researchers effectively implement its concept for developing psychological assessment instruments in sport science. The traditional concept of validity is known as content, construct, and criterion-related validity, whereas new concept of validity is not considered separate and distinct forms. That is, the varieties of validity evidence are not alternative but supplemented. Validity is not the property of an instrument but rather the meaning of test scores. There are different types of inferences for validity from test scores, but not types of validity. In this paper, the validation procedure was outlined to help researchers to develop new, translated, and modified sport psychological measures with sound evidence of validity.
