Together with her ghostwriter Rebecca Farnworth, Price has penned four memoirs since 2004, titled Being Jordan, A Whole New World, Pushed to the Limit and You Only Live Once.
Amis told The Guardian that he had read "several volumes of Jordan's autobiography" to research "incidental details" for his latest novel Lionel Asbo.
"I was rather impressed by it," he said of her memoirs.
"I was impressed by Jordan in the end, she's 'Celebrity Mum of the Year' and for good reason.
"Her oldest boy, Dwight Yorke's son Harvey, has had serious problems and accidentally hurts himself in ways that are painful to read about and she's very good and tough about that."
Asked if her books had any literary merit, he added: "That would be pushing it. They have the merits of candour and I would say a sort of honesty."
Together with Farnworth, Price has also penned eight novels, the most recent of which is In The Name of Love, published this month.
She has also put her name to the Perfect Ponies and Mermaids & Pirates children's series and 2009's fashion guide Standing Out.
Soon after the release of 2010's You Only Live Once, Price confirmed that she had started work on the follow-up, adding that the series of memoirs were "every two years... it's like a diary I do".
"I don't know why they call it autobiography, because of course it's not," she added. "They should call it the diary really."
