Description | Projective metods are commonly used in Czech republic as an auxiliary diagnostic tool. But they are often criticised for their lack of validity and reliability. This study is part of diseratation thesis and study design was based on matching technique. Participants – psychologists (N=132) had to match projective material to personality descriptions of 6 children with different psychiatric diagnoses. Projective material had been creat ed from 6 pictures of The Fantasy Animal Game (TFAG) method, 6 stories which belongs to TFAG and 6 pictures of The Tree Test. Every psychologist judged every one of 18 pictures and stories. We computed Fleiss kappa (?=0,096), that is considerd as a slight agreement. We also computed agreement for each picture and story separately. There was substantial agreement (0,64) in only one story. Remaining values ranged from 0,17 to 0,38. We also present percentage extent of right answers (matches) and percentage of certainty denoted by psychologist themselves. |
