Traditional versus Rasch Scaling of Aggregate Data in the Multitrait-Multimethod Matrix.
Turner, Carol J.; Smith, Jeffrey K.
Measurement and Evaluation in Guidance, v14 n4 p180-86 Jan 1982
Used aggregate ratings of teacher behavior as data for a multitrait-multimethod validity analysis. Scaled ratings using Rasch latent trait scaling model and traditional scaling techniques. Compared Rasch-scaled multitrait-multimethod matrix to the traditionally scaled multitrait-multimethod matrix. Results showed Rasch scaling resulted in higher correlations in general. (RC)
