The network decided to put together the special, titled Breaking the Silence, after it was reported in May that Josh Duggar had molested five underage girls -- including some of his sisters -- when he was a teenager.
The documentary will air on Sunday, August 30, and sets out to "promote education, raise awareness, and advance the conversation" on child sexual abuse.
"The one-hour documentary is built around the personal and emotional stories of brave survivors who have found the courage to come forward," the network statement said.
Added TLC President Marjorie Kaplan that "the goal is to take what has been a difficult and painful experience, and focus that attention on the really critical issue of child protection and child sexual abuse."
Jill and Jessa Duggar will also speak out in the documentary. The sisters have admitted that they were both molested by their brother Josh over a decade ago.
This won't be the first time Jill, 24, and Jessa, 22, have discussed what happened with their older sibling. In June, the girls spoke with FOX News' Megyn Kelly about the incident.
"My dad explained to us, he said, 'You know there's a difference between forgiveness and trust. That's not the same thing,'" Jill recalled. "You know, you forgive someone and then you have boundaries. Forgiveness with boundaries. Trust comes later. Josh destroyed that trust at the beginning, and so he had to rebuild that. I think when he came back, that was… the point of rebuilding."
An ET source says the Duggars are currently renting a house and have not been back to their home since the scandal.
