The order dominance scale : validity analysis.
The Order Dominance Scale (ODS) was constructed and proven reliable by Jones (2009). The scale is based on the combination of two theories; namely, Broken Windows Theory or BWT (Wilson & Kelling, 1982) and Reversal Theory (Apter, 1982). BWT provided the gap in the literature on which the personality trait of order dominance is based, while Reversal Theory provided the means with which to measure this trait. The purpose of this research was to take the completed scale constructed by Jones (2009) and test it for various types of psychometric validity. The research was able to establish predictive validity (although not in the way it would conventionally be done) and construct validity (which was established in conjuncture with convergent and discriminant validity). After going through testing for both reliability and validity, the ODS can now be considered a worthwhile scale by psychometric standards. The sample with which the data for this research was collect yielded a new set of norms for the ODS. The new set of norms gives it a mean of 31.38 with a standard deviation of 7.79, an absolute range of 0-50, an observed range of 8-48, and a reliability coefficient (alpha) of 0.7527.
