EV0290 E-PosterPerinatal and Women's HealthScale validation study # Development and preliminary validity evidence for the Disenfranchised Grief Scale in the Portuguese population PRELIMINARY DATA ON THE DEVELOPMENT AND VALIDATION OF THE DISENFRANCHISED GRIEF SCALE IN THE PORTUGUESE POPULATION Presenter: Miguel Barbosa Country: Portugal Institution: Universidade de Lisboa, Faculdade de Psicologia (CICPSI) The proposed three-factor structure for disenfranchised grief was not confirmed; instead, a two-factor structure emerged, comprising external/social invalidation and internalized grief domains. The study aimed to examine the preliminary psychometric properties of the 11-item Disenfranchised Grief Scale (DGS) in women who had experienced pregnancy loss and to compare the a priori three-factor model with alternative factor solutions. The sample consisted of 157 women with a history of pregnancy loss (mean age 38.11, standard deviation 7.93, range 21 to 67). The scale uses a 5-point Likert response format; analyses included ordinal confirmatory factor analysis (CFA) using weighted least squares mean- and variance-adjusted estimation (WLSMV), Cronbach’s alpha, omega, average variance extracted (AVE), the heterotrait–monotrait ratio (HTMT), and Spearman correlations. In the three-factor model, the latent correlation between the social/cultural devaluation and social invalidation dimensions was r = 1.07, indicating that these two dimensions could not be empirically distinguished. Fit indices were CFI = 0.870, TLI = 0.837, RMSEA = 0.248, and SRMR = 0.148 for the one-factor, 11-item model; 0.945, 0.929, 0.164, and 0.093 for the two-factor, 11-item model; 0.947, 0.928, 0.165, and 0.092 for the original three-factor model; and 0.973, 0.964, 0.120, and 0.057 for the candidate two-factor, 10-item model, which showed the best fit. Reliability estimates for the two-factor, 11-item model were alpha = 0.897 and omega = 0.917 and 0.960; for the candidate 10-item model, alpha = 0.894, omega = 0.916 and 0.840, AVE = 0.741 and 0.693, and HTMT = 0.638. Items 9 and 10 showed substantial local dependence (modification index 91.8), and removing item 9 improved model fit. Higher DGS scores were positively associated with appraising the loss as traumatic (rho = 0.35, p < 0.001) and negatively associated with perceived social support (rho = -0.41, p < 0.001). The findings suggest that disenfranchised grief may encompass both what happens to grief socially and what is internalized by the grieving person; however, the refined 10-item solution requires replication in independent samples.
