Two studies, both originating from a larger psycholexical study in Serbian language, are presented here. Two questionnaires, Lexi and PL have been constructed in the psycholexical study. The questionnaires differ by the formulation of their respective items: while the items of the Lexi contain adjectives, the items of the PL are in the form of statements. The first study presented in this paper examines the latent structure of the Lexi questionnaire, while the second one deals with the latent structure of the PL. In both studies, principal component analysis was applied, and the number of components to be retained in the analysis was determined according to the Scree criterion. Also, Promax rotation was applied in both studies. Seven components which were extracted in the first study have been interpreted as Negative Valence, Negative Emotionality, Aggressiveness, Conscientiousness, Positive Emotionality, Positive Valence and Openness to Experience. The content of these dimensions is obviously similar to the dimensions of Tellegen and Waller’s Big Seven model. In the second study, five components were extracted, and interpreted as Sociability, Anxiety, Aggressiveness, Activity and Impulsivity. The content of the dimensions extracted in the second study corresponds with the dimensions of Marvin Zuckerman’s Alternative Five - Factor Model

The Revised reinforcement sensitivity theory contains three basic systems: Behavioral inhibition system (BAS), Behavioral activation system (BIS) and the Fight/ Flight/ Freeze (FFF) system. In this model, BIS is a system for detection of potential conflict or threat, and FFFS differs three basic patterns of reaction to actual or perceived danger. In Study 1, which was aimed at the examination of the latent structure of the RSQ, was conducted on a sample of 472 participants of both genders. The best - fitting model suggests that, at the top level of hierarchy, three dimensions exist, which are analogous to the BIS, BAS and FFF. The last dimension contains three subordinate dimensions, which represent the subsystems of the FFF. Study 2, in which 203 subjects participated, was aimed at examination of the relations between the dimensions of the Revised reinforcement sensitivity theory and dimensions of the PEN model. Confirmatory factor analyses of the RSQ and EPQ-R dimensions revealed that the best-fitting model comprised three latent dimensions, the first one being analogous to the BIS - Neuroticism, the second one to the BAS - Extraversion, and the third to the Aggressiveness- Psychoticism. The structure of the latent dimensions is in accordance with the expectations. The results state that fear and anxiety (which neurophysiological distinction is emphasized by Gray), are substantively similar on the behavioral level. Also, the results suggest that the Freeze dimension is probably closer to the BIS system than to the FFF

The main purpose of this study was to evaluate personality dimensions, proposed by Big Five model, in our culture, by the use of the questionnaire FIBI, developed on the basis of the psycho lexical study of personality descriptions in Serbian language (Smederevac, 2000). There were 627 subjects in the study (407 females and 220 males), aged 17 to 77, and the inventory UKL7 (Smederevac, 2000) and the Big Five Inventory (BFI; John, Donahue, Kentle, 1991; John, Srivastava, 1999) were applied. The FIBI inventory was created from UKL7 by exclusion of evaluative items, items of probable artificial factor Emotional control and items with poor psychometric properties were excluded. Final solution with 69 items demonstrated solid psychometric properties. The construct validity of the FIBI has been assessed by examination of its relationship to the Big Five Inventory and results showed that scales Conventionality and Extraversion in those two inventories differ in content. Subscale Conventionality in FIBI was highly related to subscale Consciousness in BFI and showed no significant correlation to Openness to Experience of the BFI. The content of the FIBI's Extraversion scale includes positive self-evaluation, assertiveness and activity. Indicators of sociability, usually considered as dominant (or at least very important) markers of extraverted behavior, were omitted from the FIBI Extraversion scale. These content differences justify application of the emic approach in the personality psychology research. Although there are some other available instruments based on Big Five, FIBI represents product of our cultural background and seems to be worth of further examination and improvement

Jeffrey Gray has modified Eysenck's system by rotating the dimensions of extraversion and neuroticism by 45 degrees, which resulted in two new dimensions: impulsivity (behavioral approach system) and anxiety (behavioral inhibition system). The main purpose of this study was to examine psychometric properties of the BIS/BAS scale, inventory for assessment of dimensions included in Gray's theory, in order to, also, test the foundation of the Gray's constructs themselves. 476 participants were included, age 17 to 77. All subjects completed The BIS/BAS scale (Carver & White, 1994) and The Big Five Inventory (BFI; John, Donahue & Kentle, 1991, according to: John & Srivastava, 1999). Analysis of the BIS/BAS scale failed to replicate the original four-factor solution. Three factors were extracted, named Behavioral inhibition system (BIS), BAS-Striving for excitement and BAS-Drive. Psychometric characteristics of the BIS/BAS scale are not satisfactory. Result of the joint factor analysis of dimensions of the BIS/BAS scale and dimensions of the BFI questionnaire are three factors named active striving for reward, sensation seeking and anxiety. In general results can be considered supportive rather to Eysenck than to Gray, but they could also be ascribed to the failure in questionnaire operationalisation of the constructs of Reinforcement sensitivity theory
