Projection is a widespread mechanism of defence. It is an important is
sue in a number of anthropological researches. To estimate changes in
intensity and flexibility of the projection a measuring instrument is
unavoidable. Material: To standardise the questionnaire answers of 250
examinees were used. They were divided in two independent groups. Gro
up I consisted of 125 patients treated at Clinic for Psychological Med
icine and Group 2 of 125 students in the third year of the Medical Fac
ulty in Zagreb. Methods: To process the results a statistical package
SPSS was used. A chi(2) test was employed and tables of contingency we
re made. A factor analysis of ''The Projection Questionnaire'' was emp
loyed and varimax rotation separated five factors which characteristic
roots were greater than one. Results: A new instrument for measuring
the projection, ''The Projection Questionnaire'' is developed and stan
dardised. A considerable use of the projection by normal population is
confirmed.
