Thank you for sharing the study, it was really interesting to read. I thought that self-identified gentle parents, in practice, likely aren't hugely different from parents who do not choose that term and the study seems to reflect that, aside from the fact that it picked up that those gentle parents are very keen to do things differently from their own parents and feel more insecure about their own parenting compared with parents who don't identify with the term gentle.
Also thought it was really interesting the way it picked up on gentle parents' use of the term boundaries - I have noticed this as a reactionary thing almost, just observation of parenting forums particularly between the toddler years of my children born 2008 (gentle parenting wasn't quite a term, but the concept of non-punitive, emotion accepting parenting was there, and it was generally ridiculed and seen with a lot of scepticism - I loved it and was heavily into the theory at this time) and 2018/2021 (what we used to call gentle parenting is now the prevailing style and just called parenting, the term gentle parenting is much more mainstream with people frequently expressing guilt that they "should" be doing gentle parenting but it isn't working, the definition of gentle parenting seems to have expanded over a wider area, some of the self-identified gentle parenting content is now much more extreme and prescriptive).
It seems to me that at some point between gentle parenting being seen as a weird, niche, hippy thing and being seen as a mainstream, normal, preferable thing to do, there was some kind of virtual wrestling match over whether or not gentle parenting involved holding boundaries, since it attempts to avoid punitive responses, to the point that the gentle parent identity now has a very strong sense that yes, there MUST be boundaries, but there is not always a good individual sense of how that actually works in practice.
I was surprised though to see the study refer to this as novel - I guess this is a difference between terms used in academic research vs forum discussions or parenting books, but I thought boundaries have been considered important in parenting for a very long time. Was that term not used in Baumrind's original research? Or does it mean that parents in general don't usually emphasise their use of boundaries, but gentle parents do? (And I so want to assemble a group of gentle parents from 2013 and compare their use of language around boundaries to the 2023 parents now!)
I think there is another, separate but related shift in parenting approaches away from top-down/parent-directed, hierarchical behaviourist approaches towards more bottom-up/collaborative or democratic approaches based in developmental or neurobiological awareness. Those approaches mainly seemed to originate in approaches used with children with challenging behaviours e.g. ASD, ADHD, ODD, adopted children, traumatised children, and seem to have research-backed support in these situations - but are gaining popularity within the mainstream. I think these are distinct from "gentle parenting" which is much wider and seems to overlap both with aspects of these approaches but also with behaviourism, even though some proponents of gentle parenting reject behaviourism. But I also don't think they fit into the categories, or if they do then the closest one is likely permissive - but it's not really the same as "just letting kids walk all over you" - it's just that's really the only way you can code it if you're starting with the assumption that parents ought to be directive and hierarchical.
