Análisis del uso y la eficacia de la volea en pádel: validación del instrumento VAOP

The purpose of this study was to design and validate an observation instrument to know the characteristics of the padel volley, when, where and by whom it is performed and its effectiveness. Eleven experts participated in the process and had to meet the five inclusion criteria. Aiken's V coefficient and confidence intervals were used to calculate content validity and Cronbach's α coefficient to analyze reliability. The judges evaluated the appropriateness and wording of the fifteen designed items that were part of the initial instrument. After their assessment, two variables were eliminated for obtaining values <.91 in Aiken's V coefficient in the adequacy. The rest of the variables were modified in their wording, according to the qualitative assessments of the experts, or were considered correct. The reliability of the instrument was acceptable, (α=.89). The VAOP instrument is very novel, as it is of interest to analyze the use and effectiveness of the padel volle
