I appreciated reading the overview from 2016 covering the state of theory and evidence from that time. Sadly, from perspective of 2024, the article seemed hopeful in a way.
There's a podcast I follow called Maintenance Phase. They've completed a two-part series on the somewhat widespread adoption of a concept called rapid-onset. It's sort of the idea of a social contagion. They point out that the evidence for rapid-onset is pulled from interested populations who've self-selected. In other words, there's very limited evidence for a social-contagion theory (or rapid-onset theory). Unfortunately, there is a lot of law and policy now that is flowing from concern about a rapid-onset model.
One area I've looked at from articles since the 2016 timeframe is work on modeling the factors and mediators/moderators that may impact persons experiencing macro, mezzo and micro influences and experiences --
-- experiences, many adverse --
based on individual's personal expressions of gender or other aspects such as sexual expression, romantic interest, etc. (Meyers and other researchers).
In those models, I'm struck by the concepts of
proximal stressors (stressors close to, even internal to the person suffering difficulties in feelings or social experiences)
and concepts of
distal stressors (stressors such as treatment, adverse experiences, based on dominant social heirarchies)
An aspect of these models that makes me concerned is the way that internalized negative attitudes can become strong proximal stressors.
