title: Specific and general facets of hoarding: A bifactor model.
abstract: Whereas it has been suggested that hoarding is a multidimensional construct comprising distinct but interrelated factors (i.e., difficulty discarding, excessive clutter, and excessive acquisition), a high degree of overlap as well as a lack of discriminant validity among these factors and exogenous constructs suggests that a correlated factors approach may not adequately capture this phenomenon. The factor structure of the Saving Inventory Revised (SIR) was examined in a large non-selected clinic sample (N=490). A bifactor model of hoarding, comprising a general Hoarding factor and orthogonal Urge-Related Acquiring, Distress-Related Acquiring, Difficulty Discarding, and Clutter factors fit the data best. Further, whereas the general Hoarding factor was related to several depression facets, the specific hoarding factors demonstrated differential relations with depression. This study establishes that acquiring behaviors are motivated by both positive/urge-related and negative/distress-related emotions. Additionally, general and distinct factors should be considered to properly contextualize hoarding behavior.
