QUGRAFOR 2. Adaptation and revalidation of a training level questionnaire for rugby coaches

The scientific literature highlights the importance of the training of sports coaches and although there are different instruments to measure it in a general and specific way, few investigations create new instruments to facilitate their completion and subsequent analysis. In this study, based on the validity and reliability of the QUGRFOR (c) instrument, an exploratory factorial analysis has been carried out on 256 questionnaires, for its adaptation and revalidation. The analysis of the communalities and configuration matrix reduces the instrument from eight to five factors and from 109 to 31 items that explain a substantial amount of the variance of the instrument and show that the factors are robust, adequately discriminating between them and that there is item-factor correspondence. The reliability of the instrument was measured through Cronbach's alpha index, maintaining a good value of .89 (similar to the original). Therefore, the results obtained confirm the multidimensional structure and that it is compatible for other sports of the new instrument QUGRAFOR 2.
