Attitude scale of individuals having mental disabilities towards sports activities (zebseytö): Validity and reliability study Zihinsel engelli bireylerin sportif etkinliklerine yönelik tutum ölçeği (zebseytö): Geçerlik ve güvenirlik çalışması

In this research, it was aimed by university students to develop a measurement tool to measure the attitudes of individuals having mental disabilities towards sports activities in terms of validity and reliability. This study which was designed as a mixed model, was performed as two different working groups consisting of totally 376 university students (235 females, 141 males) in 2014-2015 Education year spring term. In order to test the validity of measurement tool, Exploratory Factor Analysis (AFA) and Confirmatory Factor Analysis (DFA) were applied. As a result of AFA, a structure including 28 items and two sub-dimensions explaining 60.988% of total variance was obtained. As a result of DFA which was carried out to confirm this presented structure, sufficient fit indices were obtained. The reliability of measurement tool was investigated by Cronbach Alpha internal coefficient of consistency and test-retest method. Cronbach Alpha and test-retest method analysis provided evidence related with high-level reliability of measurement tool. In the light of these findings, it can be concluded that ZEBSEYTO is a data collecting tool which can do valid and reliable measurements and university students can measure the attitudes of individuals having mental disability towards sports activities via this tool. Ozet Bu arastirmada, universite ogrencilerinin zihinsel engelli bireylerin sportif etkinliklerine yonelik tutumlarini gecerli ve guvenilir olarak olcebilen bir olcme aracinin gelistirilmesi amaclanmistir. Karma (mixed) modelde desenlenen bu arastirma, 2014-2015 Egitim-Ogretim yili bahar doneminde toplam 376 (235 kadin, 141 erkek) universite ogrencisinden olusan iki farkli calisma grubu uzerinde yurutulmustur. Olcme aracinin psikometrik ozelliklerine kanit saglamak amaciyla oncelikle madde analizi uygulanmistir. Madde analizleri kapsaminda, maddelerin ayirt ediciligini tespit etmek amaciyla duzeltilmis madde toplam test korelasyonu incelenmis ve toplam puan uzerinden % 27’lik alt-ust grup karsilastirmalarina yer verilmistir. Olcme aracinin yapi gecerligini sinamak icin Acimlayici Faktor Analizi (AFA) ve Dogrulayici Faktor Analizi (DFA) uygulanmistir. AFA sonucunda toplam varyansin % 60.988’ ini aciklayan, 28 madde ve iki alt boyuttan olusan bir yapi elde edilmistir. Ortaya cikan bu yapinin dogrulanmasi amaciyla gerceklestirilen DFA sonucunda, yeterli uyum indekslerine ulasilmistir. Olcme aracinin guvenirligi, Cronbach Alfa ic tutarlik katsayisi ve test-tekrar test teknikleri ile incelenmistir. Cronbach Alfa ve test-tekrar test analizleri, olcme aracinin yuksek duzeyde guvenilir olduguna dair kanit saglamistir. Bu bulgular isiginda, ZEBSEYTO’ nun gecerli ve guvenilir olcumler yapabilen bir veri toplama araci oldugu ve universite ogrencilerinin zihinsel engelli bireylerin sportif etkinliklerine yonelik tutumlarini olcebilir nitelik tasidigi soylenebilir.
