The reliability of data obtained from a modified repertory grid procedure was examined. The coordinate grid, developed by Chambers (1983), measures the logical inconsistency and integrative complexity of an individual's view of different people. 56 college students completed two forms of the coordinate grid on each of two testing occasions. Analysis indicated low reliability for measures of both logical inconsistency (r = −.04) and integrative complexity (r = .31) with respect to the people entered into the grid. The test-retest results were better (r = .51 for logical inconsistency; r = .35 for integrative complexity) but still well below acceptable reliability. Hence, generalizations beyond a particular grid may be unwarranted.
