Children's Psychological Processes Scale

Milton J. Dehn, Ed. D.

Technical Information

For the four normative age groups, the internal consistency reliability coefficients of the subscales range from .88 to .98, with the majority in the mid 90's. Validity support comes from high correlations with measures of processing skills, cognitive skills, and achievement, as well as factor analytic and developmental and developmental evidence. Compared to matched controls, LD subjects had significantly higher means on all subscales. The CPPS has high classification accuracy in regards to LD.
