Bu çalışmada aktif sporcuların antrenman ya da müsabaka sonrası karşı karşıya kalabilecekleri mental yorgunluklarının ne derece farkında olduklarını saptamaya yönelik bir ölçme aracı geliştirilmesi amaçlanmıştır. Niteliksel adımlar kapsamında literatür incelemesi sonrası madde havuzu oluşturmak için uzmanlar ile odak grup görüşmeleri gerçekleştirilmiş ve alanında uzman 70 sporcuya kompozisyon yazdırılmıştır. Niceliksel adımlar kapsamında ise geçerlik ve güvenirlik analizleri gerçekleştirilmiştir. İlk olarak oluşturulan 51 maddelik madde havuzu ve likert tipi seçimi için hazırlanan uzman değerlendirme formu, çevrimiçi olarak Lawshe tekniğine göre değerlendirilmek üzere 30 uzmana gönderilmiştir. Uzman dönütlerine göre 15 madde silinerek madde havuzu 36 maddeye indirgenmiş, likert tipi olarak ise 5’li yapı tercih edilmiştir. Deneme ölçek formu ile ulaşılan 916 gözlem (X̄yaş=20.52±6.15) için sayıltılar test edilerek AFA gerçekleştirilmiş ve 25 maddelik tek faktörlü yapı elde edilmiştir. Tekrar 613 sporcudan (X̄yaş=18.26±5.86) veri toplanmış, sayıltılar test edilerek Lisrel Programı ile DFA gerçekleştirilmiştir. Elde edilen tek faktöre ait standardize yük değerleri, maddelere ait ortak varyanslar, model uyum iyiliği değerleri ve maddelerin T değerleri incelenerek 25 maddeden oluşan tek faktörlü yapı, bir model olarak doğrulanmış ve model uyum indeksleri kabul edilebilir düzeye ulaşmıştır (χ2/sd= 1307.60/287=4.55; RMSEA=.079, NFI=.96; NNFI=.96, CFI=.96). Ölçeğe ait tek faktörde açıklanan varyans %52.486 ve cronbach alfa iç tutarlık katsayısı .96, AVE= .503 ve CR=.94 olarak hesaplanmıştır. Ulaşılan sonuçlar neticesinde ‘’Sporda Mental Yorgunluk Farkındalığı Ölçeği (SMYFÖ)’’ psikometrik özellikleri yüksek geçerli ve güvenilir bir ölçek olarak ortaya konulmuştur.

MENTAL FATIGUE AWARENESS SCALE IN ATHLETES (MFASA): VALIDITY AND RELIABILITY STUDY

Öz

The aim of this study was to develop a measurement tool to determine the extent to which active athletes are aware of their mental fatigue that they may face after training or competition. Within the scope of qualitative steps, focus group interviews were conducted with experts to create an item pool after the literature review and 70 athletes who are experts in their field were asked to write essays. Within the scope of quantitative steps, validity and reliability analyses were conducted. First, the 51-item item pool and the expert evaluation form prepared for Likert-type selection were sent online to 30 experts to be evaluated according to the Lawshe technique. According to the expert feedback, 15 items were deleted and the item pool was reduced to 36 items, and a 5-point Likert scale was preferred. EFA was performed by testing the assumptions for 916 observations (X̄year=20.52±6.15) reached with the trial scale form, and a single-factor structure of 25 items was obtained. Data were collected again from 613 athletes (X̄years=18.26±5.86) and CFA was performed with Lisrel Program by testing the assumptions. By examining the standardized loading values of the single factor, common variances of the items, model goodness-of-fit values and T values of the items, the single-factor structure consisting of 25 items was confirmed as a model and the model fit indices reached an acceptable level (χ2/sd= 1307.60/287=4.55; RMSEA=.079, NFI=.96; NNFI=.96, CFI=.96). The variance explained in one factor of the scale was 52.486% and the cronbach alpha internal consistency coefficient was calculated as .96, AVE= .503 and CR=.94. As a result, "Mental Fatigue Awareness Scale in Sport (MAFS)" was found to be a valid and reliable scale with high psychometric properties.
