Psychometric Properties of Adapted Turkish Version of ISYQOL Questionnaire in Patients With AIS
February 18, 2022 updated by: Hürriyet Yılmaz
The ISYQOL questionnaire was translated into Turkish and was assessed the psychometric properties of the Turkish version of the ISYQOL in terms of test-retest reliability, internal consistency, and construct validity in this research.

Detailed Description
HRQOL is considered one of the most relevant outcomes of both conservative and surgical treatment of scoliosis, for this reason, several questionnaires (e.g.
SRS-24 and SRS-22) have been developed.
SRS-22 has been reported as the most commonly used scale to measure HRQOL in patient with scoliosis in many countries.
However, current literature showed that SRS-22 has poor measurement properties, it does not satisfy fundamental measure requirements, i.e. additivity, generalizability and unidimensionality.
According to Rasch analysis study SRS-24 and SRS-22 presents high ceiling effects in conservative care, for the reason that was developed for surgical candidates.
The Italian Spine Youth Quality of Life (ISYQOL) questionnaire originally in Italian, is the first HRQOL questionnaire developed according to the Rasch analysis.
It was developed in a conservative treatment setting for all type of spinal deformities, including also patients with surgical curves.
The ISYQOL has recently been translated into English, however, its adaptation to the Turkish language is necessary for use in the Turkish population.
The psychometric properties of any scale may be affected by translation into another language, that's why it is important for the scale to be evaluated psychometrically.
Therefore, the purpose of this study was to translate the ISYQOL questionnaire to Turkish and to assess the psychometric properties of the Turkish version of the ISYQOL in terms of test-retest reliability, internal consistency and construct validity when used on patients with idiopathic scoliosis.

Time Frame |
---|---|---|
Turkish Version of The Italian Spine Youth Quality of Life (ISYQOL) Questionnaire
Time Frame: baseline
|
ISYQOL, is a 20-item tool used to assess spine health and health related quality of life in patients with spinal deformities.
ISYQOL was developed according to Rasch analysis.
Seven ISYQOL items assess the impact of bracing on quality of life and are to be administered only to people wearing the brace.
Because of ISYOQL is a Rasch-consistent questionnaire, it allows the comparison of the HRQOL in AIS patients who wearing and not wearing the brace.
Each item is rated on a 0-2 point Likert scale from never to often.
Total scores range from 0 to 40.
Lower scores on the ISYQOL indicate higher health-related quality of life

SRS-22 Patient Questionnaire
Time Frame: baseline
|
SRS-22 questionnaire was developed by SRS to evaluate health-related quality of life (HRQL) in patients with adolescent idiopathic scoliosis (AIS) and the Turkish version was validated in 2005.
The SRS-22 questionnaire consists of 22 items Likert type scale that allows scoring between 1-5 for each question.
SRS-22 has five domains including function, pain, mental health, self-image and satisfaction.
Subgroups can be evaluated separately, or the total score is obtained by summing up the scores from all questions.
The total score of each section ranges from 5 to 25, only the section evaluating satisfaction from the treatment is in the range of 2-10.
Scoring is obtained by dividing the total score of each section by the number of questions in that section.
Higher scores indicate better quality of life.

Re-Test Reliability of Turkish Version of ISYQOL Questionnaire
Time Frame: 4 weeks after from the first assessment
|
Test-retest reliability was assessed by calculating the intraclass correlation coefficient (ICC).ICC interpreted; proposed a classification for the strength of test-retest reliability based on the ICC as follows: less than 0.40 is poor, between 0.40-0.75 is fair to good and; more than 0.75 is excellent.
