Care of the dying evaluation (CODE) questionnaire: psychometric appraisal for application in Persian-speaking populations

Objectives

To appraise the psychometric properties of the CODE-P1 for its application to assess quality of end-stage care among Iranian patients.

Method

A forward/backward translation procedure was performed to prepare a preliminary draft of CODE-P and its face and content validity were tested by an experts’ panel. The CODE-P was completed in this cross-sectional study by 280 bereaved family members in several hospitals in Ardabil, Iran. Construct validity, internal consistency and reliability were checked.

Results

CODE-P had good face and content validity (mean impact score = 4.01 and CVI = 0.92). EFA identified five factors which worked well in terms of construct validity (factor loadings range from 0.31 to 0.84) and internal consistency (Cronbach’s Alpha = 0.91).

Conclusion

The findings supported psychometric properties of the CODE-P for assessing end-stage care quality in Persian-speaking patients. Its application for end-of-life care quality assessment could provide a base for planning evidence-informed interventions.
