Hello,

Herek developed a measure to measure attitudes to lesbians and gays...

Herek, Gregory M. (1994). Assessing heterosexuals' attitudes toward lesbians and gay men: A review of empirical research with the ATLG scale. In Lesbian and gay psychology: Theory, research, and clinical applications., (pp. 206-228). Thousand Oaks, CA, US: Sage Publications, Inc, xii, 243 pp. http://dx.doi.org/10.4135/9781483326757.n11

This is also a helpful manual...

Handbook of Sexuality-Related Measures (2011) By Terri D. Fisher, Clive M. Davis, William L. Yarber, Sandra L. Davis

Thank you very much for your help.

Dear Deena,

There's one item in the European Social Survey which has been implemented every two years since 2002 in a large survey: "Gay men and lesbians should be free to live their own life as they wish." (1 = "agree strongly" to 5 = "disagree strongly"). The data is available at http://nesstar.ess.nsd.uib.no. I think this might be interesting for you because the survey addresses the general public aged 15 years and older and there is data from 40,000 participants from over 20 countries in each round.

Thank you very much.

Hello, Deena

There is a scale developed by Costa, Machado, Bandeira and Nardi (2016) to assess prejudice against sexual and gender diversity in Brazil. It was created to meet the need for a measure that would specifically assess Brazilian cultural aspects of such phenomenon. Here, the prejudice against non-normative gender expressions is particularly intertwined with the prejudice against non-normative sexual orientations.
