Identity processes and clusters in individuals with and without pathological buying

The present study investigated the association between pathological buying (PB) and identity processes and clusters. Forty-one patients with PB and 41 gender/age-matched controls (73% females) filled out the Dimensions of Identity Development Scale (DIDS), the Pathological Buying Screener, and self-report questionnaires to assess comorbid psychopathology, such as depressive symptoms, pathological internet shopping, and hoarding (excluding acquisition). Patients with PB reported significantly higher scores on ruminative exploration and lower scores on identity commitment processes compared to healthy controls. In the total sample, as well as in the PB sample, we identified four identity clusters: troubled diffusion, moratorium, foreclosure, and achievement, similar to Marcia's identity statuses. Patients with PB were overrepresented in the troubled diffusion cluster and less represented in the foreclosure and achievement clusters. Patients with PB in the troubled diffusion cluster scored significantly higher on PB, pathological internet shopping, hoarding, and depressive symptoms as compared to patients with PB in the other clusters. Based on these findings, we can conclude that patients with identity diffusion report more severe PB and related comorbid symptomatology. PB and related symptoms may be considered as coping strategies to deal with identity-related issues.
