The study was aimed to adapt the Perception of Loneliness in Isolation Scale (ISOLA) into Turkish and to examine the psychometric properties of the scale. The sample of the methodological and cross-sectional study consisted of 154 patients who were in isolation due to COVID-19. The psychometric characteristics of the scale were analyzed by using language equivalence, content validity, confirmatory factor analysis, criterion-related validity, internal consistency, and test-retest methods. The UCLA Loneliness Scale was used for criterion-related validity. As a result of the confirmatory factor analysis of the scale, the three-dimensional structure of 14 items was confirmed and the fit index values (χ2=90.874; χ2/sd=1.317; RMSEA=0.046; AGFI=0.88; CFI=0.97; GFI=0.92; NFI=0.90) were interpreted as "good fit" or "acceptable fit". It can be said that the Turkish version of ISOLA, which is thought to contribute to understanding the loneliness of patients in isolation and solving their problems, is a valid and reliable measurement tool.
