Background: The self-efficacy of caregivers is an important matter that merits investigation, and this requires that the concept of self-efficacy be measured with a valid, reliable instrument. Materials and Methods: This research examined the psychometric properties of the Turkish version of the Revised Scale for Caregiving Self-Efficacy. A sociodemographic form and the Revised Scale for Caregiving Self-Efficacy were employed to collect data from April through December 2019. A total of 250 family caregivers were included in the study, which assessed the content validity, construct validity and reliability of the Revised Scale for Caregiving Self-Efficacy. Results: All 18 items had significant item-to-total correlations (p <0.05). The Cronbach’s alpha coefficient was 0.82 for the total scale, 0.76 for the self-efficacy in obtaining respite subscale, 0.82 for the self-efficacy in responding to disruptive patient behaviours subscale and 0.96 for the self-efficacy in controlling upsetting thoughts about caregiving subscale. Conclusion: The results of this study indicate that the Revised Scale for Caregiving Self-Efficacy is a valid, reliable measurement tool and suitable to the Turkish culture.
