Research Paper (postgraduate) from the year 2015 in the subject Psychology - Personality Psychology, grade: 10.0, Universitat Autònoma de Barcelona, language: English, abstract: Gender ideology plays an important role in human behaviour, and therefore its assessment, not only in particular areas but considering a wide variety of situations concerning both public and private life, is necessary. This study presents the Spanish version of the questionnaire developed in 1996 by Prasad and Baron, a tool for measuring gender-role cognitions, and analyses its psychometric properties in a sample of 233 Spanish undergraduate students. The questionnaire showed a 3-dimension structure -Equality, Belief and Principles- which coincided partially with the theoretical original one. Excellent reliability (Cronbach) results, of over .90, were found. Concurrent validity assessed with a measure of conservatism (E: r = -.253, p< .001; B: r = -.421, p< .001; P: r = -.123, p = .061) and with self-defined identification with feminism (E: F(2, 232) = 4.04,p=.019); B: F (2, 232) = 12.71,p< .001; P: F (2, 232) = 13.05,p< .001) was satisfactory. Scores in all dimensions differed by gender. This study reveals satisfactory psychometric properties of the Spanish version of the Prasad-Baron questionnaire, making it an appropriate tool to obtain a complete assessment of gender ideology.
