  • Does Self-Objectification Entail an Opposition Between Appearance and Competence? The Likert Version of the Self-Objectification Questionnaire (LSOQ) PSYCHOLOGICA BELGICA Wollast, R., Klein, O., VanLeeuwen, D. M., Gervais, S. J., Bernard, P. 2021; 61 (1): 33–45


    We propose a new method to test the reliability of Fredrickson et al.'s self-objectification questionnaire (SOQ). This scale being based on a ranking, traditional reliability estimates are inappropriate. Based on generalizability theory, we suggest to compute the reliability of each subset of questions related to physical appearance vs. physical competence separately in order to average them. We applied this method to a sample of female US undergraduates (n = 395) and evidenced that the reliability of the scale is very low (corrected Cronbach's alpha = .31). We also noted that a large proportion of the sample (32%) failed to complete the scale correctly. In a second study (n = 93), we propose a Likert adaptation of the scale and show that the two dimensions of the SOQ are independent. In Study 3 (n = 195), we confirm results of Study 2 and demonstrate that the general structure of the Likert version has satisfactory model fit statistics. These observations lead us to discourage the use of the original version of the SOQ and rely on the Likert version of the Self-Objectification Questionnaire (LSOQ, see appendix).

  • Two Preregistered Direct Replications of "Objects Don't Object: Evidence That Self-Objectification Disrupts Women's Social Activism" PSYCHOLOGICAL SCIENCE De Wilde, M., Casini, A., Bernard, P., Wollast, R., Klein, O., Demoulin, S. 2020; 31 (2): 214–23


    Self-objectification has been claimed to induce numerous detrimental consequences for women at the individual level (e.g., sexual dysfunction, depression, eating disorders). Additionally, at the collective level, it has been proposed that self-objectified women might themselves contribute to the maintenance of the patriarchal status quo, for instance, by participating less in collective action. In 2013, Calogero found a negative link between self-objectification and collective action, which was mediated by the adoption of gender-specific system justification. Here, we report two preregistered direct replications (PDRs) of Calogero's original study. We conducted these PDRs after three failures to replicate the positive relation between self-objectification and gender-specific system-justification belief in correlational studies. Results of the two PDRs, in which we used a Bayesian approach, supported the null hypothesis. This work has important theoretical implications because it challenges the role attributed to self-objectified women in the maintenance of patriarchy.

  • How self-compassion moderates the effect of body surveillance on subjective happiness and depression among women SCANDINAVIAN JOURNAL OF PSYCHOLOGY Wollast, R., Riemer, A. R., Bernard, P., Leys, C., Kotsou, I., Klein, O. 2019; 60 (5): 464–72


    According to objectification theory (Fredrickson & Roberts, 1997), being treated as an object leads women to engage in self-objectification, which in turn increases body surveillance and body shame as well as impairs mental health. However, very little is known about what factors could act as buffers against the detrimental consequences of self-objectification. This paper seeks to understand the role of self-compassion (the ability to kindly accept oneself or show self-directed kindness while suffering) in the perception that women have of their own bodies. Results indicate that self-compassion moderated the effect of body surveillance on depression and happiness separately among women. More specifically, for women low in self-compassion, body surveillance was negatively associated with happiness, which was explained by increased depression. In sum, our results indicate that self-compassion protects against the detrimental consequences of body surveillance.
