a

Total number of items.

b

Number of items retained following combined factor analysis.

c

Number of items retained following removal of items with response frequencies less than 5% (only impacted NEO scales).

d

Number of items retained following IRT calibration.

*

Scale was reverse-scored so higher scores indicated higher levels of personality dimension.
