Conflict measure for grids (Slade & Sheehan, 1979) based on correlations.

Conflict measure as proposed by Slade and Sheehan (1979)

Usage

indexConflict1(x)

Arguments

x: repgrid object.

Value

A list with the following elements:

total: Total number of triads
imbalanced: Number of imbalanced triads
prop.balanced: Proportion of balanced triads
prop.imbalanced: Proportion of imbalanced triads

Details

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 indexConflict2.

The table below shows when a triad made up of the constructs A, B, and C is balanced and imbalanced:

cor(A,B)	cor(A,C)	cor(B,C)	Triad characteristic
+	+	+	balanced
+	+	-	imbalanced
+	-	+	imbalanced
+	-	-	balanced
-	+	+	imbalanced
-	+	-	balanced
-	-	+	balanced
-	-	-	imbalanced
