Understanding trauma-related responses to bereavement is essential for identifying mechanisms that contribute to persistent distress following loss. Proximity-seeking behaviors, efforts to maintain closeness to the deceased, have been conceptualized as attachment-based responses that may play a central role in traumatic grief processes. However, empirical research examining these behaviors in Muslim-majority cultural contexts remains limited, and validated assessment tools are scarce. The present study examined the psychometric properties and clinical correlates of the Turkish adaptation of the Proximity-Seeking Behavior Scale (PSBS) in a bereaved adult sample (N = 200). Participants completed the PSBS along with measures of traumatic grief, continuing bonds, and depressive symptoms. Confirmatory factor analysis supported the original factor structure, and internal consistency indices indicated satisfactory reliability. Importantly, proximity-seeking behaviors demonstrated significant positive correlations with traumatic grief and depressive symptoms, indicating a pattern of co-occurrence between attachment-related proximity efforts and heightened distress in bereavement. Significant positive correlations with continuing bonds point to a meaningful association between proximity-seeking tendencies and the persistence of relational attachment following loss. These findings position proximity-seeking as a clinically relevant construct within trauma-informed bereavement frameworks. By providing a validated measure and empirically situating proximity-seeking within trauma-related symptom networks, this study contributes to the cross-cultural refinement of attachment-based models of traumatic grief.
