The Paisley club have yet to record a win this term and head into the weekend action second bottom of the Scottish Premiership.
They suffered a home defeat to newly-promoted Partick Thistle in their last outing and Goodwin believes the international break was a timely opportunity to address their problems ahead of the visit of Motherwell.
The Saints skipper said: "I think the break came at the right time for us to be honest.
"We were on a really poor run and it's given us a week or two to have a couple of team meetings, a few clear-the-air meetings, to get a few things out in the open and just start again.
"The season starts for us against Motherwell.
"We have been very disappointed up until now and we have worked really hard on the training ground over the last couple of weeks.
"Hopefully it will all come to fruition on Saturday."
Asked what has gone wrong for the Buddies so far, Goodwin added: "We've got our opinions but it's very hard to put your finger on exactly what is going wrong.
"It's certainly not through lack of effort or commitment from the players. I can vouch for that, that's for sure.
"When you look around the dressing room and see the quality that we've got, our first 11, and our whole squad really, is as good, if not stronger, than other squads out there.
"Every one of us is hurting, we are all proud lads and we realise what's happening on the park just now isn't acceptable and we hope that we can put it right."
Poor results have led to pressure mounting on boss Danny Lennon and speculation over his position at the Paisley club.
Goodwin said: "I think it's really, really early to be throwing those kind of statements out there.
"I can understand the supporters' frustration.
"We won a cup last year and I think the whole level of expectation rises and people expect us to kick on in the league.
"Our league form last year, after the cup final, wasn't particularly great and we are aware of that.
"We've got a really good team, a good squad of players, and we realise we are under-achieving just now. Just one win and the confidence will come flowing back and we can kick on from there."
Goodwin stressed the importance of the backing of the fans ahead of the visit of third-placed Motherwell.
He said: "They are a huge part of the whole thing. When the team is down there and struggling, the supporters can really be the 12th man.
"We are going through a difficult spell right now and they are hurting as much as we are. But for us to get out of it and to start winning games again, we need them on our side."
