Development of a modified instrument to measure anticipatory grieving in Jordanian parents of children diagnosed with cancer : the Marwit and Meuser caregiver inventory childhood cancer

The purpose of this article is to report on the development and field testing for validity and reliability of a modified version of the Marwit and Meuser Caregiver Inventory (MM-CGI) for the assessment of anticipatory grief among Jordanian parents of children with cancer (the MM-CGI Childhood Cancer). In 2006, a 50-item MM-CGI Childhood Cancer was administered to 140 Jordanian parents living with a child with cancer. The Cronbach ! coefficient for the total instrument was .95, and Cronbach ! coefficients for each of the 3 subscales was .91 for personal sacrifice burden, .90 for heartfelt sadness and longing, and .86 for worry and felt isolation. The construct validity of this instrument was supported by demonstrating a significant and positive correlation with the Anticipatory Grief Scale. The MM-CGI Childhood Cancer demonstrated strong convergent validity and excellent internal consistency reliability. However, further testing with a larger sample to facilitate factor analysis is needed to complete the validation process
