Psychometric Properties of the Turkish Version of the Procrastination in Exercise Scale

Öz

Exercise procrastination can lead to serious health issues such as obesity, cardiovascular diseases, chronic illnesses, and mental disorders. Although scales developed in the literature tend to focus on topics like work procrastination, academic procrastination, and decision-making procrastination, there are limited measurement tools specifically addressing exercise procrastination. This study aims to test the validity and reliability of The Procrastination in Exercise Scale, developed by Kelly and Walton, within the Turkish cultural context. The study consisted of three phases: Exploratory Factor Analysis was conducted with 406 participants (Meanage=22±2.85), Confirmatory Factor Analysis with 395 participants (Meanage=23.55±6.64), and measurement invariance analysis with 1114 participants (Meanage=32.92±11.30). The Decision-Making Procrastination Scale, The General Procrastination Scale, and the International Physical Activity Questionnaire were employed as data collection instruments. Exploratory Factor Analysis and Horn’s parallel analysis indicated that the EPBS is a unidimensional construct within the Turkish culture, explaining 81.420% of the variance. Confirmatory Factor Analysis results demonstrated a good fit for the model with values of χ2/df=4.07, RMSEA (90% CI)=.089 (.033-.13), NFI=.99, NNFI=.98, CFI=.99, and SRMR=.017. Furthermore, measurement invariance results supported structural and metric invariance (ΔCFI≤.010, RMSEA≤.015, ΔSRMR≤.030), and AVE and CR values (AVE>.841, CR>.856; CR>AVE) confirmed convergent validity. All correlations for concurrent validity were significant (p=.000). The test-retest reliability was calculated as .94, and internal consistency as .95. Consequently, the PIES is deemed a valid and reliable tool for assessing exercise procrastination behavior.

Egzersiz Erteleme Ölçeğinin Türkçe Versiyonunun Psikometrik Özellikleri

Öz

Egzersizin ertelenmesi obezite, kalp damar hastalıkları, kronik hastalıklar ve mental rahatsızlıklar gibi ciddi sağlık sorunlarına yol açabilmektedir. Literatürde geliştirilen ölçekler iş erteleme, akademik erteleme, karar vermeyi erteleme gibi konulara odaklanmasına rağmen egzersizi erteleme ile ilgili sınırlı sayıda ölçme aracı olduğu görülmektedir. Bu çalışmanın amacı, Kelly ve Walton tarafından geliştirilen Egzersiz Erteleme Ölçeğinin Türk kültüründe geçerliği ve güvenilirliğinin test edilmesidir. Üç aşamadan oluşan çalışmada Açımlayıcı Faktör Analizi için 406 katılımcıya (Ortyaş=22±2.85); Doğrulayıcı Faktör Analizi için 395 (Ortyaş=23.55±6.64) katılımcıya; ölçme değişmezliği için 1114 (Ortyaş=32.92±11.30) katılımcıya ulaşılmıştır. Araştırmada veri toplama aracı olarak Karar Vermeyi Erteleme Eğilimi Ölçeği, Genel Erteleme Ölçeği ve Uluslararası Fiziksel Aktivite Anketi kullanılmıştır. Açımlayıcı Faktör Analizi ve Horn’un paralel analizi sonuçları Egzersiz Erteleme Ölçeğinin Türk kültüründe de tek faktörlü bir yapıya sahip olduğunu ve yapıyı %81.420 açıkladığını ortaya koymuştur. Ölçeğin Doğrulayıcı Faktör Analizi sonuçları ise 2/sd=4.07; RMSEA (90%CI) =.089 (.033-.13); NFI=.99; NNFI=,98; CFI=.99; SRMR=.017 olarak yapı geçerliğinin sağlandığını göstermektedir. Bununla birlikte ölçme değişmezliği sonuçları yapısal ve metrik değişmezlik için (∆CFI≤.010; RMSEA≤.015; ∆SRMR≤.030) koşulların AVE ve CR değerleri ise (AVE>.841; CR>.856; CR>AVE) yakınsak geçerliğin sağlandığını göstermektedir. Eş zaman geçerliği için bakılan tüm ilişkiler anlamlıdır (p=.000). Çalışmanın test-tekrar test sonuçları .94; çalışmanın iç güvenirliği ise .95 olarak hesaplanmıştır. Sonuç olarak kişilerin egzersiz erteleme davranışlarını ortaya koymak için kullanılan bu ölçme aracının geçerli ve güvenilir olduğu ifade edilebilir.

Anahtar Kelimeler

• Egzersiz erteleme
