The validity and reliability of the Turkish version of the Family Inventory of Needs

The aim of this methodological study was to test the validity and reliability of the Turkish version of the Family Inventory of Needs. The universe of the study consisted of 300 family members of inpatients hospitalized in the palliative care units of four hospitals in northern Turkey between April 12, 2019 and December 30, 2019. The translation process was performed in multiple stages using the forward-backward translation model. The reliability of the Family Inventory of Needs was evaluated using the Cronbach α reliability coefficient and item-total score correlations. Exploratory factor analyses were applied to examine the factor structure of the scale and its construct validity. To test the time invariance of the scale, the relationships between the scores obtained from the first and second applications were examined using the intraclass correlation coefficient (ICC). The Kaiser-Meyer-Olkin value of the Family Inventory of Needs was found to be 0.893. The items of the Family Inventory of Needs were found to explain 45.23% of the total variance in scores. The Turkish form of the scale consisted of the importance and fulfillment subdimensions, and had 19 items. The ICCs of the test-retest scores of the importance and fulfillment subdimensions of the Family Inventory of Needs were found to be, respectively, ICC = 1.000 and ICC = 0.730 with a positive, linear, and highly significant relationship between the scores. The item-total score correlation coefficients of the scale were found to vary between 0.920 and 0.908 in the importance subdimension, and between 0.930 and 0.922 in the fulfillment subdimension. The Turkish version of the Family Inventory of Needs was found to be a valid and reliable measurement tool that can be safely used with the family members of Turkish inpatients.
