The IADC Grief Questionnaire as a Brief Measure for Complicated Grief in Clinical Practice and Research: A Preliminary Study

IADC (induced after-death communication) therapy is a grief treatment developed by Botkin that is increasingly being acknowledged for its effectiveness in various countries worldwide. In clinical practice, professionals trained in IADC therapy employ a brief evaluation tool called the IADC Grief Questionnaire (IADC-GQ) to determine whether mourning can be disturbed or stopped, resulting in complicated grief. This preliminary research aimed to establish the psychometric properties of the IADC-GQ. The factor structure was analyzed in a sample consisting of 113 participants undergoing psychological treatment who had endured the loss of a loved one for a minimum of six months. The findings revealed a two-dimensional framework comprising two distinct factors: the “Clinical Score”, encompassing the most distressing elements of grief, and the “Continuing Bond” factor, which is associated with feelings of connection to the departed and thoughts regarding the existence of life after death. The IADC-GQ has the potential to be easily and quickly employed in both research and clinical settings. Moreover, it can qualitatively assist therapists during clinical interviews by highlighting the key areas where the grieving process may encounter obstacles.
