Dignity therapy (DT) is a brief psychotherapeutic intervention with beneficial effects in the end-of-life experience. Since it provides a continuing bond between the bereaved and their loved ones, we speculated that it could be offered as a novel bereavement intervention following the patient's death. We aimed to develop, translate, and validate the Posthumous DT Schedule of Questions (p-DT-SQ), for administration with bereaved relatives or friends.

The original DT-SQ was adapted for application with bereaved relatives or friends. It was translated and back-translated to European Portuguese and revised by an expert committee. Content validity was assessed by the Content Validity Coefficient (CVC). The instrument was tested in a sample of 50 individuals from a large Senior Residence in Lisbon (10 elderly people and 40 healthcare professionals), who assessed face validity.

The p-DT-SQ showed very good CVC (0.94) and face validity: it was considered clear, easy to understand, reasonable in length, and not difficult to answer. Participants felt comfortable answering the p-DT-SQ and felt it could positively affect the way themselves or others would remember their loved ones, allowing an understanding of the deceased's concerns, interests, and values.

We created and validated an adapted version of the DT-SQ to be used posthumously by bereaved family and friends. The European Portuguese version of the p-DT-SQ is clear, comprehensible, and aligned with the fundamentals of DT. While our data suggest its beneficial effects for those who are bereft, future research is needed to examine the impact of p-DT-SQ for those who are grieving.
