99.- Technical-tactical objectives by stages for padel (TTOSP): validation of an instrument for padel coaches

The purpose of this study was to design and validate an instrument on technical-tactical objectives by stages for padel players. Twelve experts participated in the process and had to meet all the inclusion criteria. Aiken’s V coefficient and confidence intervals were used to calculate content validity and Cronbach’s coefficient to analyses reliability. The 57 items initially designed were assessed for appropriateness and wording. Three items were modified for obtaining values < .70 in Aiken’s V coefficient in the adequacy, according to the qualitative assessments of the experts. The rest of the items were considered correct because they obtained values > .79 in Aiken’s V coefficient for appropriateness and wording. The reliability of the instrument was acceptable ( = .97). The instrument is particularly innovative and valuable for defining technical-tactical objectives for padel players at various stages. Therefore, coaches and federations are urged to consider the Technical-Tactical Objectives by Stages in Padel (TTOSP) tool for coach education and player development.
