Measurement of Rod-and-Frame Test Performance

Abstract

Data from 50 male and 50 female adult volunteers were analyzed for reliability and validity of three alternative scoring systems for the Rod and Frame Test, an absolute scoring system and two alternative algebraic scoring systems. Subjects took the Rod and Frame Test, Portable Rod and Frame Test, and the Embedded Figures Test. Absolute and algebraic frame-effect scores were reliable and valid. Rod-effect algebraic scores were less reliable and valid. Correlations were higher for females and correlations with the Embedded Figures Test were so low that the interchangeability of these field articulation measures is questionable.
