Smaller correlations have typically been found between genital and subjective sexual arousal in female versus male samples. This study evaluated the association between response bias and the relationship between genital and subjective arousal (i.e., concordance) in women with (n = 20) and without (n = 21) provoked vestibulodynia. Participants (M = 21.27 years, SD = 2.27) underwent blood flow imaging via a laser Doppler imager to assess genital responsiveness to a visual erotic stimulus; subjective arousal was assessed during and following the film. The relationships between three types of subjective arousal ratings (perceived sexual arousal, perceived genital responsiveness, and reported desire to engage in sexual activity) and two forms of socially desirable responding (impression management and self-deceptive enhancement) were examined. Concordance estimates were statistically non-significant in both groups, with the exception of the desire to engage in sexual activity, which was moderately correlated with genital arousal in the control group. Impression management was not a statistically significant moderator of the relationship between genital and subjective arousal, but was moderately negatively related to the three forms of subjective arousal ratings in the provoked vestibulodynia group. The results highlight the importance of assessing response bias in laboratory studies comparing women with and without sexual dysfunction.
