Translation and validation of the Turkish version of the Subjective Index of Physical and Social Outcome (SIPSO)

Abstract

Background & Objectives: Stroke is a disease that causes disability and death all over the world. Evaluation of physical and social outcomes after stroke is important in improving quality of life and well-being. The objective of this study is translating the Subjective Index of Physical and Social Outcome (SIPSO) into Turkish and examining its validity and reliability.

Methods: This study used translation and back translation for the scale’s language equivalence and expert opinion for the content validity. An expert panel and 8 individuals with SIPSO evaluated the scale for validity. The scale’s reliability was assessed by internal consistency. Pearson correlation, and test-retest reliability were performed in 111 stroke patients. The scale’s construct validity was tested with confirmatory factor analysis and exploratory factor analysis.

Results: The Cronbach’s alpha value was 0.972, and the scale was found to have a high degree of internal consistency. In confirmatory factor analysis, it was confirmed that the scale two factors: “physical and social outcomes”. In the factor analysis, two factors emerged from the scale, and after the confirmatory factor analysis and scale modification, the fit indices of the model were found to provide a good level of validity. The scale is capable of distinguishing between introductory features and the physical and social consequences of stroke.

Conclusion: SIPSO Turkish version is a valid and reliable scale that can be used in studies evaluating the physical and social effects of stroke.
