The most defining event in a football match is scoring a goal; therefore, the analysis of the dynamics of the game and the behaviours that lead to scoring goals can provide an important contribution to the identification of each team's most decisive attacking sequences in order to propose an appropriate strategy. Thus, the aim of this study was to set up and assess an ad hoc coding tool to analyse goals in semi-professional, amateur and training football. Based on several action-research processes, and using a set of experts through the Delphi method, a field-format coding tool was designed and assessed where each criterion is an exhaustive and mutually exclusive system of categories. The results demonstrated excellent content validity values, estimated through the degree of agreement (9.37 out of 10) and importance (9.66 out of 10). Similarly, excellent intra-observer reliability values were obtained (k = .87), and good to excellent inter-observer agreement values (k = .62). The evaluation of generalisability using a three-facet design (observers, categories, goals) showed excellent reliability (G > .90), and perfect representativeness (r2 = 1), showing that the variability is explained by the categories facet (in isolation or in interaction with the other facets). In conclusion, this study provides a valid and reliable tool that allows for the identification of the teams' most representative traits through the analysis of their goals. [ABSTRACT FROM AUTHOR] |
