The relegation-threatened Magpies have suffered major defeats in their last two home games, losing 3-0 to derby rivals Sunderland then 6-0 to Liverpool, and the club have also played down reports of disharmony among their squad.
They followed up the Liverpool drubbing by drawing 0-0 at West Ham on Saturday, and regarding Newcastle's current predicament, Elliot - who played the whole of both those matches - told the Gazette: "You just have to have that self-belief. I've never been an arrogant person, but I have always had self-belief.
"You are going to get knocked down in whatever walk of life, and you just have to make sure you react. Sometimes one bad thing happens, and you can let it get on top of you.
"But everybody as a club has said we won't let it affect us. We've taken a lot of criticism on the chin, and we've just accepted it.
"The only way to answer it is to put performances in. That has been a massive plus for me as a person at the club to see that."
There had been suggestions that tension had been caused in the camp by some members of Newcastle's large French contingent not caring as much about the relegation battle into which the club has slipped.
But several players have since been quoted stressing that the group are very much working together, and Elliot added: "We showed that there was no rift at West Ham and none of this French-English thing.
"The group is together. The performances showed at West Ham. Any concerns that we aren't committed was put right then."
