PERES, Alexandre José de Souza  and  LAROS, Jacob Arie. Factor structure of the Personality Schemas and Beliefs Questionnaire. Aval. psicol. [online]. 2016, vol.15, n.2, pp.141-150. ISSN 1677-0471.

This study aimed to obtain validity evidence of the Personality Schemas and Beliefs Questionnaire (QECP) and to estimate the reliability of its scores. The QECP is a self-reported instrument developed to assess the cognitive profiles of personality disorders according to cognitive therapy theory. The sample of respondents was composed of 437 Brazilians with a mean age of 28.1 years (SD=8.57), 75.7% female and 88.3% university students. Parallel analysis was used as a criterion for the number of factors to extract in exploratory factor analysis (EFA). EFA with Principal Axis Factoring and Promax rotation indicated a five factor solution. Reliability coefficients (Guttman’s Lambda 2) of the five factors varied between .64 and .89. The correlations between the factors, corrected for attenuation, varied from .05 to .64. EFA of the factor scores indicated two second-order factors. The results indicated satisfactory evidence of construct validity and reliability of the QECP scores
