Sampdoria lost 2-0 to Palermo today in what was their seventh consecutive defeat.
"The situation is my responsibility," Ferrara told Gazzetta.it. "I have a good group of lads at my disposal and it's up to me to find the key to success.
"Will I quit? No. It's not in my character. I have to resolve the problems, not abandon the team.
"I am here to tell you that the responsibility is mine, not theirs, and fear is stopping them from playing well. I must find a solution."
Sampdoria's next game is at home against Genoa next weekend.
