Beyond Blue chairman Jeff Kennett denies there is any link between his comments on what makes a healthy family environment for children and the resignation of the national depression initiative's chief executive.

Last week Beyond Blue chief executive Dawn O'Neil resigned without explanation after just eight months in the job and she has not spoken publicly since.

The resignation came soon after Mr Kennett wrote an opinion piece in the Herald Sun newspaper in which he said happy heterosexual marriages are the best environment for the mental health of children.

"There is no substitute for parents of both genders. Happy heterosexual marriages are the best environment for the mental health of children," he wrote in the piece.

The article sparked outrage in the gay and lesbian community and forced Beyond Blue into damage control.

The then-chief executive, Ms O'Neil, spoke to JOY-FM, a gay and lesbian community radio station, to express that those views in the article were the opinions of Mr Kennett alone, and not Beyond Blue as an organisation.

Ms O'Neil then resigned from Beyond Blue later that day.

Since then Mr Kennett has resisted calls for him to step down as chairman.

And today he denies Ms O'Neil's resignation had anything to do with his comments.

"I think you'll find that is absolutely coincidental," he told the ABC.

"So rather than look at the negatives as you seem to be attempting to do, we at Beyond Blue, and I in particular, are very focused on the positives."

Mr Kennett says questioning about any possible link between his comments and Ms O'Neil's resignation is "terribly negative".

"You should just judge people and organisations on their outcomes rather than try and construe something else, and Beyond Blue's outcomes are respected by the community right throughout Australia," he said.

Mr Kennett says there have been sections of the community which have disagreed with him, but he is entitled to his own opinions.

"I don't believe I have been in trouble at all with the community as a whole," he said.

Mr Kennett denies he judged gay parents or compared them in any way with heterosexual parents.

"What I said was of all the loving relationships that are available, the one that I've grown up with, the one that I consider to be the most preferable of that was a relationship between a male and a female," he said.

"Now that is my view and I'm entitled to that view, but I do not discriminate against any loving relationship where a child is involved."

Andrew Shaw, the editor for gay and lesbian community newspaper MCV, says many in the community still have a problem with Mr Kennett's remarks.

"I believe that he is now putting a bit of spin on it and saying that is just his opinion," he said.

"I have a problem with someone who is the head of national organisation that is supposed to be fighting depression who says that what he says is simply his opinion. It is just not the case."
