REZENDE, Alessandro Teixeira et al. General Conspiracy Belief Scale (Cgbs): Development and Psychometric Evidence. Aval. psicol. [online]. 2021, vol.20, n.2, pp.127-138. ISSN 1677-0471.

The present study aimed to develop the General Conspiracy Belief Scale (ECGC), seeking evidence of its factorial validity and internal consistency. For this, two studies were carried out. In Study 1 (n=229) an analysis of the main components identified a five factor structure, each composed of three items: pharmaceutical manipulation (α=.74), global conspiracies (α=.80), manipulation by secret groups (α=.80), extraterrestrial contact cover ups (α=.92) and information control (α=.60). In Study 2 (n=229) the confirmatory factor analysis indicated that the bifactor model best fitted the data (CFI=.96, TLI=.94, RMSEA=.06). The final version of the ECGC, composed of 15 items, presents adequate psychometric evidence to evaluate beliefs in conspiracy theories, which can be used in research in the Brazilian context.

Keywords : beliefs; conspiracy theories; scale; validity; reliability.
