Measure of conflict or inconsistency as proposed by Bell (2004).
The identification of conflict is based on distances rather than
correlations as in other measures of conflict indexConflict1
and indexConflict2
. It assesses if the
distances between all components of a triad, made up of one element
and two constructs, satisfies the "triangle inequality" (cf. Bell, 2004).
If not, a triad is regarded as conflictive. An advantage of the measure
is that it can be interpreted not only as a global measure for a
grid but also on an element, construct, and element by construct level
making it valuable for detailed feedback. Also, differences in conflict
can be submitted to statistical testing procedures.
