A systematic scoping review to approach the construct of gender discrimination

Abstract Gender discrimination (GD) has been frequently linked to mental health. The heterogeneity of GD definition has led to different assessment methodologies and variation around the analysis of GD. This can affect the study of the association between GD and health outcomes. The main goal of this systematic scoping review is the review of previous studies to operationalize the definition of the GD construct. Three search strategies were set in Pubmed, CINAHL and PsycINFO. 1st and 2nd search strategies included studies if their main focus was either, the analysis of discrimination perception, triggers of discrimination or the analysis of GD effects and associated factors to its perception. 3rd strategy was focused on the identification of GD questionnaires. The prevalence of GD, factors and consequences associated with GD perception and forms of discrimination were the principal variables collected. Risk of bias was assessed (PROSPERO: CRD42019120719). A total of 925 studies were obtained and 84 papers included. GD analysis environments were described. 60 questionnaires of discrimination were identified. Prevalence of GD varied between 3.4-67%. Female gender and a younger age were the factors most frequently related to GD. Poorer mental health was the most frequent consequence. Two components of the GD construct were identified: undervaluation (different recognition, opportunities in access, evaluation standards and expectations) and different treatment (verbal abuse and behavior). GD is measured in several environments and with different methodologies. The two component definition of GD can add order and precision to the measurement, increase response rates and reported GD. Key messages The heterogeneity in the conception of gender discrimination has led to different ways of assessment and to a great heterogeneity around the analysis of GD perception. This operative gender discrimination construct could add order and precision to its measurement, increase response rates and reported GD.
