Reliability, factorial validity and normative data of the Spanish Short Interpersonal Reactions Inventory (SIRI) by Grossarth-Maticek and Eysenck

Abstract

Eysenck and Grossarth-Maticek’s model states that some of their personality types are predisposed to specific illnesses (Types 1 and 5 to cancer, and Type 2 to coronary heart disease), whereas others are preserved (Type 4) or not predisposed (Types 3 and 6). The aim of this study is to provide infor-mation as regards the reliability, factor validity and normative data of the Spanish version of Grossarth-Maticek and Eysenck´s Short Interpersonal Reactions Inventory (SIRI) in a sample of uni-versity students (N=425). The results indicate that 1) internal consistency is adequate (0,88-0,75); 2) factor analysis suggests that this instrument measures four dimensions: Factor 1 compounded by Types 1 and 2 (psychosomatic risk), Factor 2 constituted by Types 3 and 6 (hysteria/psychopathy), Factor 3 configured by Type 5 (rationality) and Factor 4 defined by Type 4 (autonomy); and 3) distribu-tion of personality types is similar to that found in prior studies with samples of young subjects.
