Functional evaluation of treatment of chronic disease: Validity and reliability of the Turkish version of the Spiritual Well-Being Scale

Abstract

Objective: This study was conducted for the purpose of adapting the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being Scale (FACIT-Sp) for the Turkish context and determining its validity and reliability.

Method: In 2016, a convenience sample of 137 cancer patients from Malatya State Hospital completed a structured questionnaire, which provided demographic characteristics, and the FACIT-Sp-12 for patients with cancer. The obtained data were assessed using Cronbach's alpha reliability coefficient (α), Pearson's product-moment correlation coefficient (r), factor analysis, Bartlett's test of sphericity, and the Kaiser-Meyer-Olkin (KMO) measure of sampling adequacy.

Results: The result of the KMO test was determined to be 0.827 and that of Bartlett's test 988.692, and both were observed to be significant at a level of p < 0.001. The value of Cronbach's α for the Spiritual Well-Being Scale (SWBS) was determined to be 0.87, and the α values for the SWBS subgroups ranged from 0.78 to 0.93. Our analysis determined that the factors had initial eigenvalues above 1, and that they accounted for 61.61% of the total variance.

Significance of results: Our study determined that the Turkish version of the FACIT-Sp has validity and reliability and can be used in Turkish society. We believe that the scale can be used safely in determining convenient care and in planning individual educational programs to enhance patients' spiritual well-being.
