Validity refers to whether a test measures what it claims to measure. In this case, the questionnaire was intended to assess impulsivity, but the items seemed to be measuring something different (i.e. sociability, outgoingness, and fun). Therefore, the validity of the questionnaire is in question. Reliability refers to the consistency of results over time, and this was not mentioned as an issue in the scenario. Standardization refers to the process of establishing certain norms or standards for administering and interpreting a test, but this was not relevant to the scenario.
