How so? If the result is similar they are just different roots to the same outcome.
The main difference is that the resilience, or the ability of a child to cope with the abuse, may vary greatly between physical abuse, sexual abuse and psychological abuse (like what the article is talking about). So a single sexual abuse is much more likley to cause Trauma, then beeing yelled at once. But beeing yelled at for years? Beeing told that you are wortheles repeatedly? That is likley to cause a lot of harm, especially because it plants a sense of “not beeing good enoth” in you that can take a lot of work to overcome once grown up.
There is no need to rank diffent kinds of abuse against each other. We need to see them as equaly harmful for children and not trivialice them.
