| description | 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. Method: All patients (N = 81) underwent a clinical interview and answered the Pathological Buying Screener (PBS), the German Saving Inventory-Revised (GSI-R), and measures for materialism, impulsiveness, depression and anxiety. Results: Seventeen patients had comorbid HD, of which 82 % hoarded predominantly purchased items. The HD+ group scored higher than the HD- group on the clutter and difficulty discarding GSI-R subscales, but not on the excessive acquisition GSI-R subscale or the PBS. There were no group differences in materialism, impulsiveness, and general psychopathology. The correlation between the PBS and the GSI-R in the total sample was driven by the high correlation between the PBS and the excessive acquisition GSI-R subscale. Higher PBS/GSI-R excessive acquisition scores were related to higher materialism and more psychopathology. Conclusion: The findings indicate that hoarding in CBSD is mostly related to purchased consumer goods and not associated with a higher symptom severity of CBSD. Further investigation into the specifics of hoarding in the context of CBSD is necessary. |
