Is there any research on positive physiological changes do to childhood abuse?

What sort of changes do you mean, and what kind of abuse? Would developing calluses where one was beaten often count as a positive physiological change? Or since this is genetics, are you talking about something positive you could pass along to an offspring? 

Sever physical abuse, and I mean changes in development during adolescence and puberty.

Sever physical abuse,

Assuming you mean "severe", that's still a subjective term. It doesn't describe the behavior to anyone who doesn't know exactly what you mean. I would consider it severe physical abuse to hit someone too hard, or more than once, while someone else may say it's only severe if you use a closed hand or weapon (stick, belt, etc).

If you mean "sever", that's extremely severe. Not sure anything positive comes from chopping off body parts.

I'm unaware of any studies done on the positive effects of childhood abuse. Such research would have a hard time avoiding looking like a justification for harming children. What sort of benefits were you thinking you might you expect to see?

From experience myself. I can say no it doesn't have any benefits Infact. Depending on of the Severity, Age and What type of abuse it can Lead to Serious Mental Health Problems.

I get the feeling you're not asking for a friend, but rather, you're afraid of your potential to harm. Nothing is set in stone, you have a choice.
