Forest have won just one of their last nine matches, and they were beaten 3-0 by Brentford in front of their own supporters in their last outing.
The Reds’ next match comes against Reading later this evening, and Vaughan says that every player at the City Ground is determined to help the side turn their form around.
“We want to put things right,” the Welsh international said. “We’ve got a point to prove to ourselves, and to the fans and manager, that we can do a lot better. Hopefully we can do that on Tuesday.
“Confidence doesn’t seem too bad. Everybody’s disappointed with the way we played on Saturday but I think people are determined to put things right on Tuesday.”
As well as a poor run of results, Forest have also had to deal with a change of management, following the sacking of Dougie Freedman.
The Scottish boss was controversially sacked last month, with Paul Williams now in temporary charge at the Midlands club.
Williams is still waiting for his first victory as Forest boss, and the pressure is on him to find the winning formula quickly.
Although Forest are still comfortably clear of the relegation zone, they will need one more victory to feel totally assured that they will keep their place in the second tier for next season.
