The Unbearable Weight of Gender Inequalities: Development and Validation of the Social Treatment and Experiences of Women (STEW) Scale

Gender inequalities are pervasive across various life domains, yet research has often overlooked how people perceive that women are treated differently than men. To fill this gap, we developed and validated the 16-item multidimensional Social Treatment and Experiences of Women (STEW) scale across different samples of women and different cultural contexts, namely Italy and the UK N = 1,195). Using exploratory (Study 1, N = 703) and confirmatory (Study 2, N = 550; Study 3a, N = 132; Study 4, N = 201; Study 5, N = 233) factor analysis, we identified four dimensions: workplace inequalities, domestic imbalance, harassment towards women, and social expectations. Studies 3a and 3b (N = 96) demonstrated convergent, discriminant, and predictive validity of the STEW, linking the STEW's subscales to group-based emotions, reported experiences of sexism, attitudes towards affirmative action, and attitudes towards women's sexual freedom. Replicating the factor structure in the UK, Study 4 found the STEW explained unique variance in group-based emotions and intergroup attitudes beyond personal experiences of sexism. Last, Study 5 showed that the STEW explains unique variance in collective action intentions and feminist identification beyond people's attitudes towards gender equality. Highlighting the importance of conceiving gender inequalities as a multifaceted issue, the STEW provides a robust tool for assessing perceptions of differential treatment of women across domains and can inform more comprehensive interventions promoting gender equality.
