Brief Summary

Cerebrovascular diseases are the leading cause of disability, work loss, and quality of life reduction, the third leading cause of death globally, and significantly impact hospital admissions and expenses. This prevalence rises with an aging population and comorbidities. Recognizing stroke symptoms quickly is crucial for timely treatment. Miscommunication or misunderstanding among hypertensive patients, who are at the highest risk for stroke, increases stroke risk and complications. Educating the public about stroke symptoms and responses is essential for prevention. Therefore, a valid and reliable tool to assess hypertensive patients' stroke knowledge is important for improving long-term outcomes. This research aims to adapt the Stroke Knowledge Test into Turkish and evaluate its validity and reliability in hypertensive patients.

Detailed Description

Cerebrovascular diseases are the group of diseases that cause the most disability and loss of work, affect the quality of life the most and are the third leading cause of death in the world, and also have a significant place in hospital admissions and expenses. This rate increases with the aging population and comorbidities. The recognition of stroke symptoms by the society is the most important factor in patients reaching treatment opportunities without wasting time.

It is known that failure to provide accurate information to hypertensive patients, who are the highest risk group for stroke, or the patient's failure to understand stroke is associated with a higher risk of stroke and complications. These findings indicate that it is important to provide information to the public about how they behave when they encounter symptoms related to stroke and related conditions. Measuring stroke knowledge and risk factors in hypertensive and potential stroke patients can serve as a healthcare provider who informs the society to adopt stroke prevention behaviors.

Therefore, a valid and reliable assessment tool is of great importance in determining whether hypertensive patients have sufficient knowledge about stroke and improving the long-term clinical outcomes of stroke.

This research aims to perform the cross-cultural adaptation of the Stroke Knowledge Test into Turkish and to examine the validity and reliability of the assessment tool in hypertensive patients.

Study Groups

Stroke patients

Translating the Stroke Knowledge Test into Turkish and Related Processes

Intervention Type: OTHER

The first step is the translation from the original language to the other language. The ideal target in the translation phase is to use people who are familiar with the structure of the original language and who are familiar with the language. Two forward translation and one reverse translation methods will be applied after obtaining the written permission of the authors. After the completion of this phase, the terminological differences arising from the translators in the translation process from the original language to Turkish will be collected and discussed on the questions. The cultural adaptation study will be terminated by determining the equivalence between the Turkish version of the test and the English original. The final version of the questionnaire and the necessary changes will be arranged specific to the investigator's society and the authors of the original questionnaire will be consulted and the questionnaire will be finalized.

Validity

Intervention Type: OTHER

Content validity will be calculated with the Content Validity Index, which is a result of 10 expert opinions in terms of clarity, difficulty, and suitability of the Turkish version of the Stroke Knowledge Test. For face validity, the final version of the form will be provided with opinions from 3 stroke patients.

Internal consistency and Reliability

Intervention Type: OTHER

The internal consistency of the items will be tested with Cronbach alpha. Test-retest reliability will be tested with intraclass correlation coefficient.
