Attitude towards oneself and others in non-clinical population, depressed and paranoid examinees.

Background: The theoretical concept of existential/life positions describes person's basic beliefs about oneself and others. Most of authors on TA postulated that every person has one of four possible basic life positions: I'm OK, you're OK; I'm not OK, you're OK; I'm OK, you're not OK and I'm not OK, you're not OK. The aim of this study was the authentication of Existential positions as theoretical concepts in Transaction Analysis, and it's potential to discriminate clinical from non-clinical examinees, and paranoid from depressive examinees within the clinical population.
