The Efficiency of Various Estimations of Reliability of Rating ScalesUniversity of Bielefeld, West Germany Twelve variance-analytical and non-parametrical coefficients of reliability for rating scales designed for rating persons, are being compared to each other theoretically and empirically. The empirical comparison is produced with the help of over 20.000 ratings, which 54 subjects delivered in two, antagonistical as far as their reliability was concerned, test instructions. The preference for two coefficients ( rkrand and rkfix') has been established. The ICC appears to be useful for the estimation of reliability as well.
