Barton helped the Clarets win promotion to the Premier League last season and has returned to the club, scoring the winning goal against Southampton on Saturday, after an unsuccessful spell at Rangers.
"He has been back in the group in the last few weeks and he has settled in," said Dyche. "He knows most of the staff and players and knows what we expect so I was never worried about that.
"To be fair, he has had an interesting life and he gets used to what comes with his life. He does not over think it and just looks forward. He does not get an easy ride from fans and he is used to it, so I don't think he worries about it, he just thinks what he can do for the team."
