Translation and validation study for the stroke self-efficacy questionnaire in stroke survivors
1School of Nursing, Koç University, İstanbul, Turkey.
Background:
Self-efficacy has been shown to play an important role in rehabilitation outcomes of stroke patients.
Aim:
This study aimed to determine the validity and reliability of a Turkish translation of the Stroke Self-Efficacy Questionnaire.
Methods:
This methodological study was conducted in a private acute stroke unit in Istanbul, Turkey. After obtaining the Institutional Review Board's approval and site consent, a translated version of the 13-item Likert-type scaled questions was tested for language and content validity. A pilot study with 10 patients was followed by recruitment of 130 stroke patient participants, with 50 patients retested after 3 weeks.
Results:
The Stroke Self-Efficacy Questionnaire-Turkish had excellent content validity index and face validity index scores. Confirmatory factor analysis findings revealed a single factor structure that offered good model suitability. Cronbach alpha was 0.93 for the scale and its subgroups. There was no statistically significant difference between the items according to test-retest scores (P > 0.05), and a reliability index was over 0.80.
Conclusion:
The Turkish version of the Stroke Self-Efficacy Questionnaire is a valid and reliable tool, recommended for use in clinical rehabilitation and stroke self-management/self-efficacy interventions.

Regulation of Stroke Volume
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
