Criterion validity refers to the extent to which a measure is related to an outcome or criterion, in this case, the participants' self-identification as political conservatives. The fact that participants who identified as political conservatives also scored the highest on the researcher's questionnaire suggests that the questionnaire has criterion validity. Content validity refers to the extent to which a measure assesses all aspects of a construct, face validity refers to the extent to which a measure appears to measure what it is intended to measure, and predictive validity refers to the extent to which a measure can predict future outcomes. While these types of validity are also important, the scenario described primarily demonstrates criterion validity.
