The psychometric properties of the Turkish version of the Self-Regulatory Fatigue Scale

Abstract

Purpose The aim of the study was to translate and adapt the Self-Regulatory Fatigue Scale (SRF-18) into Turkish and also demonstrate its reliability and validity in young adults.

Design and Methods A total of 181 participants completed SRF-18, Life Orientation Test-Revised (LOT-R), Brief Self-Control Scale (BSCS), and Multidimensional Fatigue Inventory (MFI). One week later 30 participants refilled SRF-18.

Findings The internal consistency of SRF-18 was good (α = 0.710). The intraclass correlation coefficient value of the SRF-18 total score was 0.608. SRF-18 was strongly related to MFI and LOT-R (r1 = −0.632, r2 = 0.557, p < 0.001). Besides, there was a moderate relationship between SRF-18 and BSCS (r = 0.439, p < 0.001). In addition, SRF-18 had a three-factor structure.

Practice Implications The Turkish version of the SRF-18 was proven to be a valid and reliable tool.
