Psychometric properties of Persian version of the Caring Dimension Inventory (PCDI-25)

The purpose of this study was to examine the psychometric properties (validity and reliability) of Persian version of the 25-item Caring Dimension Inventory (CDI-25). A psychometric instrument validation study was designed. Content validity, internal consistency, and stability were confirmed. A total of 288 participants (143 nurses and 145 nursing students) were selected based on quota sampling approach. The PCDI-23 showed good test–retest (Spearman correlation coefficient of 0.89 for nursing students and 0.91 for nurses), internal consistency reliability (0.86), and acceptable face and construct validity. However, considering the results of analyses, excluding items 4 and 16 from the Persian version of the CDI is suggested. This instrument can be used to determine caring behaviors and nurses’ perceptions of the importance of caring behaviors among Persian language nurses.
