Attitudes towards Lesbian, Gay, Bisexual and Transgender Old Age Scale (EAFV- LGBT): Elaboration and Psychometric Evidence.

The aim of this study was to construct and validate an Attitude Scale relating to Lesbian, Gay, Bisexual and Transgender (LGBT) old age (EAFV-LGBT). The first study, consisting of 29 items in its preliminary version, counted on 266 individuals from the public in general with an average age of 28.6 years (DP = 9.70), exploratory factor analysis was undertaken and EAFV-LGBT consisted of twelve items, with eigenvalues of 5.08, accounting for 43.8% of total variance. The second study consisted of 261 individuals from the general public with an average age of 23.18 years (DP = 8.25), confirmatory factor analysis was undertaken and psychometric parameters by means of Item Response Theory and conformation of the EAFV-LGBT structure. After this analysis, two items were excluded due to lower psychometric values, in which the 10 item scale proved to be valid and precise in evaluating individuals with varying levels of the latent trait. An adequate fit of the model to the data was verified, CFI = 0.97; TLI = 0.6; RMSEA, 90% CI = 0.05 [0.01, 0.07]. Lastly, the EAFV-LGBT has valid psychometric properties to evaluate attitudes towards LGBT old age.
