Developed by psychologist Dorothy Riddle in the mid-1970s, it was regarded as a pioneering work in synthesizing and recording differing attitudes toward people with alternative sexual preferences. Thus while this scale has since been expanded and updated since it popularization in 1994, it is still the work against which all other scales are measured.
Most notable elements of the scale are that tolerance and acceptance are categorized as moderately negative attitudes, with the premise that these hold a sense of “putting up with” the community, rather than fully embracing homosexuals as a social normative.
For myself, I have to make a daily, conscious effort to move from support toward nurturance everyday particularly with Transgender friends, since this has most recently encountered my worldview.
