Polish adaptation of the quality of relationships inventory-Bereavement version.

We examined the psychometric properties of the Polish version of the Quality of Relationships Inventory-Bereavement Version (QRI-B) in a sample of 241 persons bereaved after the death of a family member from 0.5 to 8 years (M = 3.36, SD = 2.02) before the survey. A good fit of the original two-factor (Closeness and Conflict) model of the QRI-B was determined by confirmatory factor analysis. Cronbach's alpha was .91 for Closeness and .84 for Conflict. Closeness correlated negatively with attachment avoidance and Conflict correlated positively with attachment anxiety. The Polish version of the QRI-B is a valid and reliable measure of the quality of the pre-loss relationship with the deceased.
