- Abstract
In research studies, patient-reported or clinician-administered scales are commonly preferred for measurement activities. Due to the complexity of understanding the true impact of a disease on a patient's life and the variability of the disease experience from person to person, patient-reported scales are widely used in the literature. All scales used for shoulder diseases in Turkey are adapted scales. In the scope of our planned scale development study specific to the Turkish population, the stages of scope determination, expert opinions, and ensuring content validity were conducted for a new scale. Through literature review, expert opinions, and patient reports, the scope of the intended scale to be developed was determined as the assessment of shoulder functionality. A pool of 34 items was created by considering symptoms expressed by shoulder patients, articles containing patient expressions in the literature, developed scales for the shoulder in the literature, and clinician opinions. An expert panel consisting of 8 specialists was established to test the content validity and linguistic validity of the item pool. Expert opinions were obtained twice digitally through the Google Forms platform for the items in the pool. After the first expert opinion, the content validity rate (CVR) for 5 items was 0,778 or higher. The first expert opinions and the items were revised based on the CVR, resulting in a revised pool of 21 items. The revised item pool was sent again to the same experts through the Google Forms platform for reevaluation. The CVR was calculated for the items again based on expert opinions. After the second expert opinion, it was observed that 20 items had a CVR value of 0,778 or higher. One item with a CVR value below 0,778 was removed from the scale. According to these results, the total content validity indeks (CVI) of the scale was calculated as 0,984375, and the draft scale consisting of 20 items reached its final form. The concepts of CVR and CVI were explained in simple terms in the context of our sample study to illustrate how they would be used in the scale development process. The use of different CVI thresholds in studies was analyzed.
