[Correction Notice: An Erratum for this article was reported online in Journal of Personality and Social Psychology on Nov 19 2020 (see record 2020-89294-001). In Table 4, the mean, standard deviation, and range for the Personal Safety Anxiety and Vigilance (PSAVS) variable were incorrect.] Objectification Theory posits that everyday encounters with sexual objectification carry a diffuse nonspecific sense of threat that engenders personal safety anxiety in women. In this article, we provide direct evidence for this tenet across 5 studies and 1,665 participants using multiple methods. Study 1 (N = 207) and Study 2 (N = 161) explored and confirmed the factor structure of the Personal Safety Anxiety and Vigilance Scale (PSAVS), a measure of personal safety anxiety, and provided evidence for the reliability and construct validity of its scores. Study 3 (N = 363) showed that personal safety anxiety is a conceptually different construct for women and men, and differentially mediated the relation between sexual objectification and restricted freedom of movement and the relation between self-objectification and restricted freedom of movement for women and men. Study 4 (N = 460) included a comprehensive test of personal safety anxiety within an expanded Objectification Theory model, which supported personal safety anxiety as a mediator of the links from sexual and self-objectification to women's restricted freedom of movement. Study 5 (N = 474) replicated these results while also adjusting for specific fears of crime and rape. Our findings offer a newly validated assessment tool for future research on safety anxiety, illuminate the real and lasting sense of threat engendered by everyday sexual objectification, and broaden understanding of the mental and physical constraints on women's lived experiences posited in Objectification Theory.
