The 19-year-old stunned the sporting world 12 months ago as her aggressive approach propelled her to the title without dropping a set.
Raducanu vowed afterwards to keep the same free-swinging attitude, but now accepts that was much easier said than done with expectations sky high and attention on her every move.
She told the PA news agency: “I think looking back I can say there’s been many months in the year since that I haven’t actually been swinging freely.
“It’s very easy at the time but, when you have absolutely no idea what’s about to hit you, to say something like that, I was still on that energy from those two weeks. Obviously a lot of stuff has happened since.”
Since becoming the first player ever to win 10 matches at the same slam, Raducanu has failed to win more than two at any tournament, so the chances of anything approaching a repeat appear very slim.
But she at least arrived at Flushing Meadows with some positive momentum after reaching the third round in Cincinnati last week, beating Serena Williams and Victoria Azarenka before losing a close contest with top-10 American Jessica Pegula.
Raducanu, who is having a trial period with Russian coach Dmitry Tursunov, was also being noticeably more aggressive again and she intends to maintain the same approach.
“There’s been tournaments for sure where I wasn’t doing that, but I’m very pleased with Cincinnati... playing Serena and Vika back to back and having a pretty tight match against Jessie – my level was definitely showing some positive signs,” she said.
“Results and wins – they don’t come by often, but when they do you have to really cherish them and take the positive energy. I do take the confidence of knowing I have the ability to produce that sort of level.
“To play Vika and Serena – it’s not necessarily all about tennis: a massive part is mental, just to stay focused, not be intimidated by who you’re playing on the other side of the net.
“To have that belief which I did have in Cincinnati, I think I’m just going to carry that through and try and keep that up here.”

This was a much more positive session than Friday’s, when Raducanu broke down in tears, sparking concerns about another potential injury.
She put it down to a bad day and it would not be surprising if being back at Flushing Meadows was a little overwhelming for the teenager.
“Twelve months – it’s obviously a bit of a long time, but coming back here it honestly feels like I’ve never left,” she said.
“Coming to the city, it’s just gone so quickly. So much has happened, but I feel like I was here yesterday or last week. It’s a really strange feeling. I’ve obviously learned a lot, but time flies.”
