A researcher wanted to investigate whether there was a relationship between authoritarian personality and obedience to authority. Before the study began, she devised a questionnaire to measure authoritarian personality.
To assess the questionnaire's validity, the researcher gave it to 40 participants and recorded their scores. She then gave the same 40 participants an established questionnaire measuring authoritarianism (the F-Scale). The researcher found a weak positive correlation between the two sets of scores, suggesting that her new questionnaire had low concurrent validity.
Explain how the validity of the researcher's questionnaire could be improved.
