Abstract
⺠It is important to maximise the precision of personality measurement in adolescents. ⺠We apply item response theory (IRT) to the NEO-FFI in an adolescent sample. ⺠IRT was used to assess item validity and highlight poorly performing indicators. ⺠Removing poor items reduced measurement error without compromising validity. ⺠IRT analysis can be used to develop personality measures ensuring item validity.
