Abstract
An age-neutral measurement system is one of the basic conditions for an accurate personality assessment across the lifespan, both longitudinally and cross-sectionally. In this study the age-neutrality of the Personality Inventory for DSM-5 PID-5; Krueger et al. (Psychological Medicine 42, 1879–1890, 2012) was investigated. Potential Differential Item Functioning (DIF) was examined for the 25 trait facets in older versus younger adults. Overall, 33 items displayed large DIF, according to the adjusted Bonferroni corrected cutoffs (Mantel Chi-square, Liu-Agresti Cumulative Common Log-Odds Ratio [L-A LOR], and Cox’s Noncentrality Parameter Estimator [Cox’s B]). In a next step, the implications of the item level DIF across age groups was investigated on scale (i.e., facet) level. These Differential Test Functioning (DTF) analyses revealed large DTF for four of the 25 PID-5 facets (i.e., Withdrawal, Attention Seeking, Rigid Perfectionism and Unusual Beliefs). Current initial results show that most PID-5 traits are measured equally well across age, however, further research is needed to further refine this instrument and make it entirely age-neutral.

Notes
The exact cutoff values for each of the three DIF indicators for each analysis can be obtained on requested from the first author.
In deriving their thresholds Penfield and Algina (2006) argued that a collective large level of DIF in a group of items exist if 25 % or more of the items are categorized as having moderate or large magnitudes of DIF based on the ETS classification scheme (i.e. if 25 % or more of the items have an absolute value of log(αMH) greater than or equal to .43. They also suggest that MH and L-A LOR have similar meanings in terms of DIF magnitude. Because we wanted to reduce the Type I error, a Bonferroni correction was applied and adjusted L-A LOR cut-off values were used to flag items with large DIF (depending on the number of items per scale). In line, we made a similar adjustment for the DTF thresholds. For example: Penfield and Algina consider the variance of DIF effect large when weighted v2 > .14, using an L-A LOR value of .43 as critical value. Since we adhere to stringent L-A LOR critical values (for example > .92 for Anhedonia) we adjusted this to v2 > .35 (i.e., .14/.43*.92).
