Anomaly In Equation For Calculating 16pf Second Order Factor Qiii, Gregory J. Boyle

Gregory J. Boyle

Recently, the Institute for Personality and Ability Testing (IPAT) has released a new set of equations for calculating 16PF second-order factors. These revised equations were compared with the earlier ones provided in the l6PF Handbook, as well as with those used in the Clinical Analysis Questionnaire (CAQ) for computing the second-order trait dimensions. It was found that the earlier 16PF Handbook equation for calculating QIII (Tough Poise) was not accurate. It is recommended that only the new equations be employed in future work with the 16PF. Moreover, this finding may have implications for published studies involving the 16PF second-order factors …
