The Scale of Observing the Opponent in Sport: Validity and Reliability Study

This study aimed to develop a valid and reliable measurement tool, the Scale of Observing the Opponent in Sport (SRAS), to identify focal points athletes consider when observing their competitors. Combining qualitative and quantitative steps, the scale's development included focus group interviews, essay writing, expert review (Lawshe technique), assumption analyses, and exploratory and confirmatory factor analyses. The initial 36-item pool was expanded to 46 items based on expert feedback, and a 5-point Likert-type (5=Always, 1=Never) trial form was administered to 508 active athletes. Exploratory Factor Analysis (EFA) revealed a 4-factor, 30-item structure, subsequently confirmed through Confirmatory Factor Analysis (CFA) on 491 observations. Factors were named based on literature review: "Tactics-Strategy" (n=6, α=.86), "Communication" (n=5, α=.73), "Technical-Physical" (n=11, α=.92), and "Image" (n=8, α=.86). The overall scale demonstrated high reliability (α=.93), and the explained variance ratio was 55.941%. Despite abundant research on athlete motivation, the lack of instruments measuring critical observation factors underscores this study's significance. The SRAS fills this gap, providing a valid and reliable tool to assess observation levels in active athletes, potentially contributing to performance enhancement strategies and talent identification.
