Factor Structure and Gender Stability of the Brazilian Version of the Pornography Consumption Inventory
There are a few instruments available to measure pornograhy consumption related constructs, and this lack of instruments can compromise the validity of research findings. The Pornography Consumption Inventory (PCI) assesses four motivations for pornography consumption, and it has been validated in hypersexual men and medical students. However, whether the psychometric properties of this instrument are comparable across genders remains unclear. Multigroup confirmatory factor analysis (MGCFA) was used to verify the invariance of the structure of the PCI across male (100) and female (105) university students. The confirmatory factor analysis (CFA) for each group showed a reasonably good fit of the data to the four factor model. The MGCFA model included only factor loadings constrained to be equal between both genders (DCFI 0.01 and p 0.05) However, the DCFI did not support a strong and strict factorial invariance, DCFI 0.01. Although both genders seemed to agree with the conceptualization of pornography and motivations for consuming it, the PCI was not gender invariant, as men showed a stronger degree of motivation to consume pornographic material than women did. The implications of these findings regarding the measurement of motivations for pornography use are outlined.
