As I recall, they claimed damages for all the family, but for different reasons. In the case of the parents the damages were to compensate them for their pain, suffering and emotional distress. They felt;
"totally destroyed, depressed, feeling ashamed and experiencing a deep malaise because they are considered as having responsibility in the disappearance of their daughter and as coward people who have hidden her body, simulating a kidnapping."
That claim wasn't proved, but this was;
"Because of the statements made by defendant Gonçalo Amaral in the book, in the documentary and in the interview to Correio da Manhã, authors Kate McCann and Gerald McCann suffer permanent anguish, insomnia, lack of appetite, anxiety and irritability, preoccupation and indefinable fear."
With a caveat;
"The judge adds that this psychological state is predates the book launch, the documentary and the interview and was not caused by them. Nonetheless, it is not unreasonable to believe that the book, the documentary and the interview had an effect on the couple, i.e. It had an effect but that is to be expected."
The judge seems to be saying that they did feel that way, but the feelings weren't caused by the book, the documentary or the interview.
