Adams, 30, is confident Wales can halt the losing streak.
“We probably have just got a little bit lost and are trying to find our way back now,” said Adams.
“That’ll come because the talent is there. I know I see it every day, these boys are as good as what we’ve had and are good enough to produce and win.
“It’s just confidence is a huge thing.”
The British and Irish Lions wing says the desire and commitment is there to change Wales’ fortunes.
“It is horrible to question that, although I know it can be questioned when you are looking in because of the results and magnitude of some of them,” said Adams.
“That hurts the playing group. They have lost and lost badly on occasions, but it doesn’t affect the amount of effort that goes in. That can never be questioned.
“There will be a tipping point. We all believe that and hope it will be this summer. “
Adams says the squad have spoken about the situation they are in.
“It’s something we have addressed because there is no point in not talking about things,” said Adams.
“The more open and vulnerable we can make each other as players in speaking about different aspects of the game and life, the easier it becomes to talk about difficult things.”
