Mbia moved to Loftus Road from Marseille over the summer, with the Cameroon international among a number of high-profile acquisitions made by Mark Hughes.
He, like many of his fellow recruits, has been unable to steer QPR away from trouble this season, with the club still looking for their first win of the campaign and now working under the guidance of Harry Redknapp following the decision to relieve Hughes of his managerial duties.
Mbia's first taste of life in the Premier League has been far from pleasant, but the midfielder insists he retains full faith in both his ability and that of the club to generate positive results.
"I am very happy to be here with QPR," he told the club's official website ahead of Saturday's home date with fellow strugglers Aston Villa.
"I believe we have a good team and I am looking forward to this weekend."
Mbia, who has been asked to fill a variety of positions in an effort to aid the collective cause added: "I feel I will get better and better. I have played centre back, right back and midfield. My best will come when I have stability in my position.
"Is midfield my preferred position? I don't mind. What's important is that I help the team. I want to work hard for everybody, and the team is more important than anything else.
"I want to do my very best for the team and for the coach, in training and in matches. I want to see us winning games. I don't like to lose. When I lose I am not happy. All the players are the same."
On the battle which lies ahead for all of those connected with QPR, with the club sweating on their top-flight status, Mbia added: "The Premier League is very difficult, but we want to win on Saturday for the fans.
"We haven't won all season and this annoys me. It hurts. But it is a challenge and I want to help my team. I want to give everything, I want to give all my heart to this challenge."
