The development and validation of the Brief Experience of Caregiving Inventory (BECI).

ABSTRACT

BACKGROUND: The social network supporting an individual with psychosis may be adversely affected by the experience of caregiving. The Experience of Caregiving Inventory (ECI) is 66 item self-report measure of the impact of caregiving for carers of people diagnosed with psychotic disorders. This study aimed to create a brief version of the ECI, and evaluate its reliability and validity (n = 626). METHODS: The validation process was conducted through a Multidimensional Item Response Theory (MIRT) approach, using a graded response model and a complementary network approach. RESULTS: This resulted in a 19 item, four factor inventory with a good model fit, displaying good reliability and validity. CONCLUSION: The BECI is a valid measure. The simplicity, ease of application and robust psychometric properties further enhances its acceptability and usefulness as a brief measure in clinical research and trials, as well as in routine practice providing reliable and valid data on experience of caregiving in families of an individual with psychosis.
