dc.description.abstractAbstract: The current study evaluated a bifactor model for the Obsessive-Compulsive Inventory Revised (OCI-R) in two samples, with (n=188) and without (n=408) obsessive-compulsive disorder (OCD). Since the OCI-R has been traditionally conceptualized as a correlated six-factor instrument, our goal was to evaluate the fit of a bifactor model against three competing models (one general factor, six correlated factors and a hierarchical model). Results revealed that the bifactor model presented the best fit and that all OCI-R items were influenced by a general factor and by one of the six dimensions. Model-based reliability estimated via Omega hierarchical for the total score suggested that OCI-R items are multidimensional, with the general obsessive-compulsive (OC) factor accounting for little more than half of the variability in the items of the total score, with the remaining variability accounted for by the specific OC domains and other sources of variance. Measurement invariance of the bifactor model was also supported among those with and without OCD. Implications for better understanding the structure and further use of the OCI-R are discussed.pt_PT
dc.description.abstractResumo: Este trabalho avaliou a adequação dum modelo bifatorial ao Obsessive-Compulsive Inventory Revised (OCI-R) em duas amostras, com (n=188) e sem (n=408) perturbação obsessivocompulsiva (POC). Dado que o OCI-R tem sido tradicionalmente conceptualizado como um instrumento de seis fatores correlacionados, o nosso objetivo foi o de avaliar o ajustamento dum modelo bifatorial, testado contra três modelos concorrentes (um fator geral, seis fatores correlacionados e um modelo hierárquico). Os resultados revelaram que o modelo bifatorial apresentou o melhor ajuste, e que todos os itens do OCI-R foram influenciados por um fator geral e por uma das seis dimensões. A fidelidade deste modelo, estimada através do Ómega hierárquico para a pontuação total, sugere que os itens do OCI-R são multidimensionais, com o fator obsessivo-compulsivo geral (OC) a representar pouco mais de metade da variabilidade nos itens da pontuação total, com a variabilidade restante atribuível às dimensões específicas de OC e a outras fontes de variação. A invariância do modelo bifatorial foi também verificada nos grupos com e sem POC. São discutidas implicações para uma melhor compreensão da estrutura e posterior utilização do OCI-R.pt_PT
