OBJECTIVES: There is a long standing theory, suggested that there are personality traits, which in combination coping strategies and biomedical factors can predict cancer or coronary heart disease in healthy probands (Hansen, Floderus, Fredriksen, Johansen et. al, 2005).
The Multiple methods were used to develop suggestion authors this new Personality/Stress Questionnaire that there are personality traits, stress and coping strategies which in combination with physical variables can predict cancer or CHD in healthy probands in 81% accuracy (Grossarth-Maticek, Eysenck, Boyle, 1991, 1995, ).
This study examines the predictive accuracy of three different methods of administration of a questionnaire designed to predict and divided the population into four types: Type 1 as a cancer prone, Type 2 as a coronary heart disease CHD prone, Type 3 is alternating between behaviors characteristic of Type 1, 2, and 4 and this thereby protected to some extent, and Type 4 as a healthy, autonomous type hypothesized to survive best.
METHODS: From the global healthy probands sample (n= 1 087 (both sexes), we were selected (N=131) men and women aged 24-65 completed three methods: The Personality/Stress Questionnaire, Ipat Anxiety Scale and 37 Adjective Check List ACL. For these studies used statistical multiple package: The Classification Trees Module with two algorithms CART (Classification and Regression Trees), Discriminant Analysis, Logistic Regression and Correlation R-Spearman. STATISTICA 8 PL was used for analysis.
RESULTS: The largest share in the variation for all presented models showed the second Type, as CHD prone (characterized by an overarousal, open behavior pattern) in potentially healthy probands. Classification of the TREE`S analysis demonstrated that in 83,19 % can classify peoples in terms of belonging to one of four types correctly. In Discriminant analysis in 97,11% (R=0.900, the value of Wilk`s Lambda statistics=0.190, Chi square= 188,85, DF= 30). In the Linear Regression in 68,7% (p=.0001, R2=592,7, DF=16, F=156,8) can classify peoples in terms of belonging to one of four types correctly.
CONCLUSIONS: The findings suggest that The Personality/Stress Questionnaire is an appropriate and effective method for eliciting peoples for one of four types` personality and coping strategies. But such studies should be carried out on a large number of peoples (longitudinal and follow-up study), having regard to the cultural differences and biomedical factors.
