I had all the things that you said where done to you done to me. I also have all three things the study mentioned.
Just because you can "remember" these things does not directly impact your adult mental state. I was beaten with a belt, had my mouthed washed out with soap, beaten by my five siblings, yet I am not depressed, have anxiety, nor am I paranoid. I also believe, looking back, I justly deserved everything and it taught me boundaries and respect.
Seems like these data collectors love to twist all kinds of things around to make their hypothesis meet the numbers. "What? You're child just died and you are depressed? And you were spanked as a child? Therefore, being spanked = adult depression." Such b.s.
