It looked at more than 2,000 parents and showed that they regularly feel cut off from others.
Eben Marks, from Action for Children, told Premier socialising with new people can be daunting for parents: "When you're an adult, you sort of think, 'can I still make friends? Isn't that a thing children do?'
"But it's never too late. It doesn't matter how long you've been lonely or isolated for, you're not beyond making new friends."
More than a third of parents aged 18-34 said they regularly feel cut off, compared to just eight per cent of those over the age of 55.
Additionally a third of parents with three or more children said they often feel isolated, compared to 26 per cent of parents who have two children.
He added that everyone's situation is different: "We think there's a lot of reasons for this, partly because society is a lot more mobile than it used to be, people have to move for work a lot more, people's families might have moved away from there or vice versa.
"There's also women who have been in work and built up social networks that way, if they leave work to have children it can then be quite difficult for them to re-build the kind of networks they had before.
"And some people obviously face issues in their lives that can end up isolating them from other people."
