Abstract
The present study investigated the (co-)occurrence of non-suicidal self-injury (NSSI) and pathological buying (PB) and their associations with reactive/regulative temperament in a sample of female patients with eating disorders (ED) and in a sample of community adults. Our samples consisted of 254 community adults (48.8% female) and 60 female patients with ED. All participants filled out self-report questionnaires to assess NSSI, PB, and reactive/regulative temperament. Prevalence rates of NSSI and PB were respectively 14.5% and 4.8% for community women, 13.1% and 1.5% for community men, and 36.7% and 10% for female patients with ED. Only for community women, NSSI was positively related to PB. NSSI was negatively related to self-regulation in community men and women. Additionally, NSSI was negatively predicted by BAS reactivity in the clinical sample and by the interaction of BAS reactivity and self-regulation in community men. PB was predicted by low self-regulation in the three groups. Additionally, PB was positively predicted by BAS reactivity and by the interaction of BAS reactivity and self-regulation in community women. These findings indicated group differences in the (co-)occurrence of NSSI and PB and in their associations with underlying temperamental characteristics between individuals with and without ED.

During the past decades, there has been a growing interest in the co-occurrence of different pathological behaviours
In this study, theoccurrence of non-suicidal self-injury (NSSI) and pathological buying (PB) was investigated in a sample of female patients with eating disorders (ED) and in a sample of community adults
Summary
There has been a growing interest in the co-occurrence of different pathological behaviours. Patients with ED seem more vulnerable for both NSSI and PB, research about the co-occurrence of NSSI and PB in clinical or community samples is lacking. In the present study, we examined associations between NSSI and PB in a sample of patients with ED and in a sample of community adults. We examined possible common vulnerability factors of NSSI and PB in both samples. Temperamental characteristics are frequently considered to be important factors underlying different types of psychopathology (Bijttebier et al, 2009). Identifying common and distinct temperamental characteristics of NSSI and PB in both clinical and community samples can lead to a better understanding of these behaviours and their co-occurrence
