Recent research on grieving populations has emphasized the role of meaning making in adaptation to bereavement, typically relying on simple self-reports of the extent to which respondents have been able to find sense or benefit in their loss. The present article reports the development of a reliable and comprehensive coding system for analyzing meanings made in the wake of the death of a loved one, yielding a 30-category codebook demonstrating excellent reliability, and comprising both negative and positive themes that arise as grievers attempt to make sense of loss. Based on an intensive qualitative analysis of a diverse sample of 162 adults mourning the natural or violent death of a variety of loved ones, the Meaning of Loss Codebook could prove useful in process-outcome studies of grief therapy, analysis of naturalistic first-person writing about bereavement experiences in grief diaries and blogs, and clinical assessment of meanings made in the course of bereavement support or professional intervention.
