The SI-R is a 23-item questionnaire with 3 sub-scales for difficulty discarding, excessive clutter, and compulsive acquisition. The total score ranges from 0 to 92. The greater the score, the more severe the hoarding symptoms. Total score higher than 41 shows significant difficulty with clutter. For the acquisition subscale, items 2 (reverse score), 9, 11, 14, 16, 18 and 21 are summed together. The subscale ranges from 0 to 28 and score greater than 13 indicates difficulty with excessive acquisition. For the difficulty discarding subscale, items 4(reverse score), 6, 7, 13, 17, 19, 23 are summed together. The subscale ranges from 0 to 28 and score greater than 13 indicates difficulty with discarding. For the clutter subscale, items 1, 3, 5, 8, 10, 12, 15, 20, 22 are summed together. The subscale ranges from 0 to 36 and score greater than 15 indicates difficulty with accumulated clutter. Response was defined as at least a 14 point change (pre-post) in the total score.
