There is substantial evidence that identifies and supports a division between two qualitatively distinct forms of dissociation. However, there is currently no scale designed to differentiate these types of dissociation. The purpose of this study is to describe the development and validation of the Detachment and Compartmentalisation Inventory (DaCI). The DaCI was derived from the structural dissociation mode, 29 existing dissociation scales and expert opinions. An initial pilot study was conducted to assess readability, explore validity and reduce items before the DaCI was administered online to 89 non-clinical and 105 clinical participants. The Dissociative Experiences Scale (DES), Mindfulness Attention Awareness Scale (MAAS) and Somatoform Dissociation Questionnaire (SDQ) were included as part of the survey battery for validity measures. The final version of the DaCI is a 22-item, self-administered instrument that is grounded in theoretically literature and support by statistical analysis to assess, (1) compartmentalisation (10 items) and (2) detachment (10 items). The two further items assess the validity of participant responses. The DaCI demonstrated good internal reliability, convergent validity, discriminant validity, concurrent validity and construct validity. The DaCI was designed for clinical research and for screening patients presenting with dissociative symptoms. This study found the scale had solid psychometric properties and could differentiate compartmentalisation and detachment.
