Stage 6 involved creation of the Inconsistency Index. The Inconsistency Index is one of the two validity measures of the Bar-On EQ-i: YV ™, which was designed to assess response consistency. It was found that the Bar-On EQ-i: YV ™ contains several pairs of highly correlated items that have similar content, which were used to gauge response consistency. Ten pairs of Bar-On EQ-i: YV ™ items were thus selected to be used in this index - two pairs for each of the five primary scales - in that they demonstrated the highest correlations within each of these five scales. The Inconsistency Index score is computed by calculating the absolute value of the difference in the response to each pair, and then summing these 10 differences. Some degree of response inconsistency is natural and expected, especially since there are subtle differences between the items in each pair that were selected. As such, it was determined that a score of 10 or greater should be treated as atypical in terms of response inconsistency. Highly inconsistent responding typically occurs with noncompliant or unmotivated respondents and can compromise the validity of the results when the degree of inconsistency is significantly high; and the most likely interpretation for high scores on the Inconsistency Index is that the individual is responding haphazardly or in an unmotivated fashion, and / or he or she is deliberately trying to invalidate his or her results for one reason or another. However, elevated scores on the Inconsistency Index can also mean that the respondent is experiencing difficulty understanding the subtle differences between some of the items. High scores on this index may also be indicative of a lack of self-awareness. The construction of this scale, including the cutoff score, followed a complicated process which is described in detail in the instrument's technical manual.
