Psychometric evaluation of “Family Inventory of Needs” in parents of cancer children

Background: Early childhood cancer creates various challenges in parents' lives and influences new needs, the identification of which requires a valid and reliable tool. Objective:The aim of this study was to translate and validate the Family Inventory of Needs (FIN) with the parents of children with cancer. Method: In this methodological research, 210 parents of children with cancer visiting pediatric oncology referral centers in Iran were selected through convenience sampling, based on the study inclusion criteria. The Farsi version of FIN was developed through translation and back-translation. Face validity as well as construct validity using the confirmatory factor analysis (CFA) were performed. The correlation between the score of FIN and the score of Caring Ability of Family Caregivers of Patients with Cancer-mothers’ version (CAFCPC-mother's version) was also calculated in order to evaluate the convergent validity. Furthermore, the stability and internal consistency reliability were investigated using software packages LISREL and SPSS. Results: The results of CFA showed that the single-factor structure of the tool with 20 items has an appropriate fit with the data and is therefore approved. Pearson coefficient (r) of the correlation between the mean scores of the NFI and the CAFCPC-mothers’ version was calculated to be 0.17 (p < 0.01). The Cronbach's alpha of the tool was calculated as 0.90, and the test-retest correlation coefficient as ICC = 0.91. Conclusion: The Farsi version of the FIN has appropriate psychometric properties among the population of Iranian parents of children with cancer. It may therefore be a suitable tool for measuring the emotional, physical, and psychological support provided for the parents of children with cancer.
