QUINONES, Y et al. The positional attack in handball: validation of an observation system. CPD [online]. 2019, vol.19, n.3, pp.114-124.  Epub 22-Jun-2020. ISSN 1989-5879.

In this study an observation instrument is presented to analyze the positional attack actions in high level handball. The tool has been designed ad hoc using a mixed system of field formats and a system of exhaustive and mutually exclusive categories (E/ME). It is made up of 12 criteria and 62 categories, which propose as main criteria the situation produced by the imbalance, the collective tactical means employed and the execution of the decision. An analysis of Data Quality and an analysis of Generalizability. Correlation coefficients (Pearson, Spearman, Tau b de Kendall) and Cohen Kbibra index were estimated for both sexes. The correlations estimated for male sex were (.97-.99) for intra-observer reliability and (.89-.98) for interobserver reliability. Cohen's Kbibra index was .94 and 0.82 respectively. The female sex obtained an intra-observer correlation coefficient of (.95-.97) and (.87-.98) in the inter. Cohen's Kbibra index was 0.91 in the inter concordance and 0.81 in the intra. The results have shown adequate correlation indices as well as excellent Generalizability results with a relative G and absolute G value of .99 in the inter-observer agreement and 1.00 for the intra-observer agreement. As a novelty, an invariance analysis was carried out to demonstrate that there are no gender differences in the use of the tool. The data generated from the study ensures that the observation tool is highly valid, accurate and reliable.
