Following a summer that saw the club sign 10 new players, the R's have endured a difficult start on their return to the top flight.
However, Caulker is hopeful that supporters at Loftus Road will remain patient while new signings such as himself bed in.
"I just urge the fans to stick with us. We are a new team and we're gelling together, but don't doubt us. We have got a lot of spirit in the dressing room and we're confident we're going to stay up this year," he told the club's official website.
QPR are currently in the relegation zone on goal difference after winning just one of their first five games of the season.
