Validity, internal consistency, and responsiveness of the Turkish version of The Family Needs Questionnaire-Revised

Abstract

ABSTRACT Objective The aim of this study is to conduct validity (language, content and confirmatory factor), internal consistency and responsiveness properties for Turkish version of the Family Needs Questionnaire-Revised (FNQ-R). Methods It was carried out with 185 family members who met study inclusion criteria and provided care for the patients with TBI. Sociodemographic characteristics form and the FNQ-R were used as data collection tools. Validity was assessed by language validity, content validity and confirmatory factor analysis. Internal consistency and item-total correlation were used for reliability analysis. Responsiveness analyses were evaluated with infit and outfit statistics, person–item maps and point biserial correlation. Results The language validity of FNQ-R was provided by translation-back translation. The content validity index values were above 0.80. Fit indices were at an acceptable level in confirmatory factor analysis. Cronbach alpha of subscales was found to be between 0.69 and 0.85 and Spearman–Brown split-half reliability was between 0.68 and 0.85. A positive and significant relationship was found between the subscales. The item fit statistics were at the acceptable level. Conclusion It has been determined that the FNQ-R is a valid and reliable measurement tool to identify the needs of the family members who provide care to patient with traumatic brain injury and can be used for Turkish population.
