Data were kindly made available by H. C. M. Vorst from the University of Amsterdam. The original Adjective Checklist was developed by Gough and Heilbrun (1980).

Details

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 were reversed. llcll{ Communality Items 1-10 Change Items111-119 Achievement Items 11-20 Succorance Items121-129 Dominance Items 21-30 Abasement Items131-139 Endurance Items 31-40 Deference Items141-149 Order Items 41-50 Personal Adjustment Items151-159 Intelligence Items 51-60 Ideal Self Items161-169 Nurturance Items 61-70 Critical parent Items171-179 Affiliation Items 71-80 Nurturant parent Items181-189 Exhibition Items 81-90 Adult Items191-199 Autonomy Items 91-100 Free Child Items200-209 Aggression Items 101-110 Adapted Child Items210-218 }
