Multitrait scaling is a straightforward yet elegant methodology for scale analysis. The procedure involves examining item frequencies; item and scale descriptive statistics (e.g., mean, standard deviation, variance); scale internal consistency estimates; item-scale correlations (corrected for overlap); and correlations among scales. The Multitrait Analysis Program (MAP) provides the statistics needed for multitrait scaling analysis. To use MAP on a VAX computer, the user must supply two input files — a raw data file and an input specification file (map.in) containing a series of keywords. This user's guide specifies how to set up the MAP input file, provides an example using MAP on a VAX-780, and summarizes published examples of multitrait scaling.
