The second idea is that when children in a family are continually invalidated by their parents, they start to give them what the children think they want: saying and doing things which literally invite other people to invalidate them. I at first thought that maybe Linehan was re-discovering the wheel, but then I went back to the old book to look at how they defined disqualification.
To my surprise, disqualification is something one does to oneself, not to someone else.
Such a person will disqualify what they are trying to get across just in case it is unacceptable to others.
If it is, then they can claim that they were merely misunderstood.
Patients with bulimia nervosa scored higher on levels of paternal invalidation than those with anorexia nervosa.
