Conflict measure as proposed by Slade and Sheehan (1979)
The first approach to mathematically derive a conflict measure based on grid
data was presented by Slade and Sheehan (1979). Their operationalization is
based on an approach by Lauterbach (1975) who applied the balance
theory (Heider, 1958) for a quantitative assessment of psychological
conflict. It is based on a count of balanced and imbalanced triads of
construct correlations. A triad is imbalanced if one or all three of the
correlations are negative, i. e. leading to contrary implications. This
approach was shown by Winter (1982) to be flawed. An improved version was
proposed by Bassler et al. (1992) and has been implemented in the function
The table below shows when a triad made up of the constructs A, B, and C is balanced and imbalanced.
