First, since its development, the dimensionality of the OBQ has been controversial.
In the present study, we examine to what extent the limitations observed using the OBQ are also identifiable when another instrument specifically designed to measure OCD-beliefs is applied.
Several other studies also examined the structure of the OBQ (Faull, Joseph, Meaden, & Lawrence, 2004; Julien, O'Connor, & Aardema, 2007; Myers, Fisher, & Wells, 2008; Sica et al., 2004; Woods, Tolin, & Abramowitz, 2004; Wu & Carter, 2008).
Although different OCD-related scales and different methods were used, studies of the links between OCD symptom subtypes and belief domains produced results supporting the relationship of dimensions of the OBQ to OCD.
A recent analysis conducted on a previous 87-item version of the OBQ revealed three empirically derived factors that correspond to cognitive constructs hypothesized to be highly relevant to OCD: 1) responsibility and threat estimation, 2) perfectionism and intolerance for uncertainty, and 3) importance and control of thoughts (OCCWG, 2005).
Participants in the four experimental groups did not differ with respect to age, F(3,96) = 1.75, n.s., nor did they differ in terms of their mean total scores on the BDI, F(3,96) = .45, n.s., the BAI, F(3,96) = 2.44, n.s., the VOCI, F(3,96) = 1.85, n.s., or the OBQ, F(3,96) = .24, n.s.
Means and standard deviations of the PI-R, OBQ
, BDI, and OPIS are shown in Table 1.

Three components were derived as a result of factor analysis by retaining 44 items out of 87 in the initial long version of the OBQ

En ambos casos, el OBQ
esta formado por tres dominios de creencias: Responsabilidad/Estimacion de la amenaza, Perfeccionismo/Incertidumbre e Importancia/Control de los pensamientos.
