Assessing Reliability

Validity Indices
The correlation between scores on the revised GENE scale and the other six instruments
are presented in Table 2. As indicated in Table 2, scores on the revised GENE scale were
statistically and significantly correlated with scores on the Travelling to Other Countries scale,
r (88) = -.412, p < .001, the Working with Foreigners scale, r (88) = -.370, p < .001, Gudykunst’s
Ethnocentrism scale, r (88) = .420, p < .001, and the Patriotism scale, r (88) = .372, p < .001.
The correlation between scores on the GENE and scores on the CETSCALE was in the expected
direction, but was not statistically significant, r (88) = .191, p = .074. Scores on the GENE scale
and the interdependent and independent Self-Construal scales were not statistically significant,
r (88) = -.112, p < .301, and r (88) = -.023, p = .834 respectively.
Discussion
In very general terms, there are two fundamental properties of empirical measurements;
that is, reliability and validity. Reliability refers to the extent to which some measurement tool
yields approximately the same results over repeated trials. Validity refers to the extent to which
some measurement instrument measures what it is intended to measure. The results presented
here provide some initial evidence that the revised GENE scale is a reliable and valid index of
ethnocentrism. Based on the data present here and elsewhere, reliability estimates are well
within an acceptable range
