Bournemouth manager Lee Bradbury admitted his side are lacking self-belief after their promotion hopes were dealt yet another blow by the 1-0 defeat at Carlisle.
Peter Murphy's first-half strike condemned the promotion-chasing Cherries to their third straight defeat.
Murphy netted after 26 minutes with a close-range left-foot finish and Bradbury said: "That's three defeats on the spin which isn't great for us but we've got to keep our self-belief.
"We're determined to be successful and I'm sure we will come out of it in the end.
"You get dips in form at times but ours has come towards the end of the season.
"We haven't picked up points in three games which is reality. But it was one of those games we should have won really and on another day we could have done so if we'd been more clinical."
