Validity refers to the extent to which a measure assesses what it is intended to measure. If Dr. Sheffield's measure does not actually measure pathological gambling, then it lacks validity. Reliability refers to the consistency of a measure, which is not applicable in this scenario. Conceptualization refers to the process of defining a concept and its properties, while operationalization refers to the process of defining how a concept will be measured. Dr. Sheffield has already defined the concept of pathological gambling and created a measure to operationalize it, so neither of these terms applies to his potential issue with validity.
