To hoard or not to hoard purchased items - does it matter? A clinical cross-sectional study on compulsive buying-shopping disorder.

Background: Research with individuals with compulsive buying-shopping disorder (CBSD) indicated that comorbid hoarding disorder (HD), as determined by questionnaire cutoffs, is associated with more severe CBSD. This study investigated a clinical sample with CBSD and determined the prevalence of HD by clinical interview, explored whether hoarding refers to consumer goods and/or non-purchased, free items, and compared patients with (HD+) and without (HD-) comorbid HD regarding materialism, impulsiveness, general psychopathology, CBSD and HD symptoms. Additionally, the relationship between CBSD symptoms and other study variables was explored in the total sample.
