The document discusses how researchers created a series of pictures showing different levels of clutter in rooms to help accurately assess clutter problems. People can pick the picture that best matches the clutter in their living room, kitchen and bedroom. While no two homes are exactly alike, this rating system generally works well as a measure of clutter. The researchers would encourage people to get help for hoarding if the clutter in their home reaches the level of picture #4 or higher. These pictures are published in treatment manuals and self-help books on hoarding from the Hoarding Center.
