Howe admitted the Cherries have had their confidence knocked by four defeats in their first four games but, ahead of Friday's home game with Brighton, he has refused to question the attitude and desire of his squad.
"I wouldn't question the attitude of my players, yes the performances but never the attitude. You see trends, you see the attitude and how we want to work and want to win. That's all there, he said.
"They haven't lost that, we just haven't delivered on game day. That's frustrating for them, frustrating for me. Absolutely we've got to keep our nerve, and I don't think it's far away from clicking at all."
Howe's men have been beaten by West Brom, Watford, Manchester City and Arsenal so far and he admits the performance levels have been mixed but he hopes his players deliver the goods when it matters most soon.
He added: "We gave a good account of ourselves against Manchester City and you can get beaten by Arsenal at any time given the quality of their players.
"West Brom away is a tough game, and the Watford game would be a disappointment for us in terms of how we played.
"The trouble is in this league you can find a way to get beaten by anybody, so we just have to have a cool head, stick to what we know we can do and deliver."
Bournemouth and Crystal Palace remain the only Premier League teams yet to get off the mark on the points front this term ahead of this weekend's fixtures with the Cherries second-bottom as they have at least managed to score one goal so far.
