zola: Correlation matrix of 135 self report and 30 peer report personality items

Description

Zola et al., (2021) reported the validity of self report personality items from the SAPA personality inventory (SPI) (Condon, 2018) in terms of 30 peer reports on 8 dimensions. Here are the polychoric correlations of these items. spi items were collected using SAPA procedures for 158,631 participants (mean n/item = 18,180), 908 of whom received peer ratings.

Usage

data("zola")

Format

The format is: num [1:165, 1:165] 1 -0.242 0.282 0.65 0.223 ... - attr(*, "dimnames")=List of 2 ..$ : chr [1:165] "q_253" "q_4296" "q_1855" "q_90" ... ..$ : chr [1:165] "q_253" "q_4296" "q_1855" "q_90" ...

Details

The polychoric correlation matrix of the spi and peer report data. To see the item labels, use the lookupFromKeys .

This data set is a nice example of a multi-trait, multi-method correlation matrix. (see the scoring example). Five dimensions of self report show high correlations with the corresonding peer report scales.
