Abstract :

Measurement in psychology that consist multiple unidimensional scales whether the composite of the entire test items measure several psychological attributes was little discussed. This study compared reliability precision estimation among seven methods to estimate the reliability under three different multidimensional factor-structure conditions. Data was generated by simulation study on three multidimensional condition (parallel, tau-equivalent, congeneric). The result revealed that the three methods (Alpha Stratified, Mosier Coefficient, Wang Coefficient) estimated the true reliability much better than Composite, Construct and Maximal Reliability Coefficient. Study also found that in the multidimensional condition, Alpha Coefficient consistent as lower bound estimator of reliability. Comparisons among the seven methods are outlined.
