Participants
The sample has been described elsewhere.30 A total of 17,263 individuals aged 6 to 17 years were recruited for the Thoughts, Actions and Genes (TAG) project at the Ontario Science Centre in Toronto, Ontario, Canada. Parents of children aged 6 to 15 years or participants aged 13 to 17 years provided consent, completed rating scales for OC, hoarding, and ADHD traits, and responded to questions about history of medical/psychiatric conditions diagnosed in the community (referred to henceforth as
Results
Hoarding and OC symptoms were common among children from our community sample: 8.9% (n = 1,483) were hoarding-positive and 6.1% (n = 1,013) were OC-positive. The overlap of hoarding-positive and OC-positive was substantial (n = 661; 60%) but not complete (χ2 [1, n = 3,930] = 936.6, p < .001) (Table 1). The hoarding-positive group was 10.5 times more likely than the hoarding-negative group to be OC-positive (95% CI = 9.0–12.4). If parents rather than youth themselves filled out the TOCS, the
Discussion
This study is the first to examine the correlates of high hoarding with and without high OC symptoms in children and adolescents in the community. We demonstrated that hoarding existed in the absence of OC symptoms in 40% of youth. Approximately 10% of our participants were classified as hoarding-positive (both hoarding symptoms; a score of +2 or more on both hoarding items), and more than 40% of these participants were classified as OC-negative (no OC symptoms; scores of –2 or less on all OC
