The objective of this study is to analyze the internal validity of the score of the STAI questionnaire, which was created by Spielberg in 1964 with the aim of measuring the construct of state anxiety and trait anxiety. 97 participants completed the STAI questionnaire, and the obtained results were analyzed using two different statistical methods: factorial analysis and network analysis. It was hypothesized that the factorial structure identified in the data collected form the questionnaire aligns with the arrangements proposed by Spielberg in 1964. This arrangements involves a two- factor internal structure, with one factor capturing state anxiety and the other representing trait anxiety. The results revealed a two-factor structure for the STAI questionnaire, thus confirming the structure initially proposed by Spielberger in 1964. Regarding the state anxiety scale, a two- factor structure emerged, however, it does not reflect the dimensionality highlighted in the literature. Regarding the trait anxiety scale, analyses revealed a two-factor structure that is in agreement with the structure highlighted in the literature. Afterwards, an abbreviated version of the STAI questionnaire was developed with the most representative items of the state anxiety and trait anxiety constructs. This version revealed a four-factor structure. In conclusion, the analysis of the internal validity of the STAI questionnaire revealed structures that diverge from those proposed in the literature, suggesting alternative interpretations of the construct.</p> Dewey 150 Maîtrise universitaire en psychologie 108 Section de psychologie 71 false 87cafe43-7fd7-462c-8807-244cfce32954 Master thesis Restricted GRITTI-Anna_septembre-2023_MEMOIRE.pdf 5021243 application/pdf 17a34044a164db03fde830bcee603fced1b84fc7ba3856927b7b5ebda53d9953 restrictedAccess Faculté de psychologie et des sciences de l'éducation / Section de psychologie
