Use of the Core Bereavement Items in Adults Aged 50 and Older: A Psychometric Evaluation.

The Core Bereavement Items (CBI) is a commonly used measure that assesses core grief and bereavement experiences. Although previous psychometric testing has been conducted, no studies have assessed its use specifically aimed at adults aged 50 and older or for those who lost a loved one who was hospice care. This is critical, as losses and additional obstacles in bereavement compound throughout the aging process. The present study investigated reliability, content validity, and internal structure of the CBI in bereaved adults aged 50 and older whose loved one died while in hospice care (N = 205). Associations based on age, marital status, and relationship with the died patients were consistent with preexisting research. Results of a Cronbach α reliability test found that the CBI has excellent reliability in this population. Further, content validity was established based on the judgment of subject matter experts. Exploratory factor analysis supported a 1-factor structure, with all items loading as General Grief Experiences. Based on this analysis, the CBI is a valid and reliable tool when used with adults aged 50 and older.
