Assessing the Reliability and Validity of the Generalized Ethnocentrism Scale
Unformatted Document Text:  Assessing Reliability 11 one study has shown that scores on the revised GENE score are predictive of other attitudes and perceptions. Amos and McCroskey (1999) found that those high in ethnocentrism were significantly more likely than those moderate or low in ethnocentrism to perceive negative attitudes and expectations on the part of teachers. They also found that those low in ethnocentrism were more likely than those normal and high ethnocentrics to report higher levels of teacher nonverbal immediacy. Neuliep and McCroskey (1997) reported that scores on the original 24 item GENE scale were predictive of the frequency of contact with people from a different country and people from a different culture.

Construct validity refers to the extent to which a measurement device is related to other theoretically consistent measures.
