Scores of 433 students on 218 items from a Dutch version of the Adjective Checklist.
data(acl)A 433 by 218 matrix containing integers. dimnames(acl)[[2]] are adjectives
Each item is an adjective with five ordered answer categories
(0 = completely disagree, 1 = disagree, 2 = agree nor disagree, 3 = agree, 4 = completely agree).
The respondents were instructed to consider whether an adjective described their
personality, and mark the answer category that fits best to this description.
The 218 items constitute 22 scales (see table);
77 items of the 218 items that constitute the ten scales were negatively worded.
The negatively worded items are indicated by an asterisk in the dimnames
and their item scores have been reversed. The Deference scale measures in fact the opposite of Deference.
