The Cherries slipped to a 2-1 defeat to Chesterfield and have now gone four league games without a win, including three losses.
"That is four matches now without a win, but perhaps we are seeing the other side of things now because in the past we won a couple we didn't deserve to," said Howe.
"We need to be brave now and stand up to be counted because we might have got a point out of it in other circumstances. But the quality is there, and we just have to keep working."
Howe admitted his side's downfall against Chesterfield was a tale of two contrasting halves.
He added: "We were poor in the first half and excellent in the second. I don't know why we were so poor, but we were nervous on the ball and Chesterfield deserved to be in the lead."
