Assessing the impact of cognitive differences in the treatment of obsessive-compulsives

Demonstrated a set of research techniques that combine multidimensional scaling, a quantitative cognitive procedure, and cost outcome analysis. The multidimensional scaling results supported Reed's (1969) notion that obsessive-compulsive clients are underinclusive and did not support Foa and Steketee's (1979) contention that they are overinclusive. Significant differences in extent of follow-up therapy were found between obsessive compulsives (N = 12) with the underinclusive cognitive style and those with a normal cognitive style.
