COLLET, C; NASCIMENTO, JV; FOLLE, A  and  IBANEZ, SJ. Desing and validation of an instrument for analysis of sportive formation in volleyball. CPD [online]. 2019, vol.19, n.1, pp.178-191.  Epub Aug 17, 2020. ISSN 1989-5879.

The aim of this study was to develop and verify the content validity and reliability of the Sports Training Instrument in Volleyball (IAFDV). Participated in the content validity process 12 expert judges who met the selection criteria. In order to verify the reliability (stability and internal consistency) participated 15 players from volleyball training categories. The content validity was analysed from the V Aiken, the stability of the instrument was analysed through the Spearman coefficient and the internal consistency by means of the Cronbach's Alpha coefficient. The results show the high content validity indexes (.91) and reliability of the instrument, taking into account that 77 of the 78 items presented a significant correlation (p <.05) and high internal consistency (α >.70). Thus, it is considered that the questionnaire is adequate and has satisfactory validity and reliability to measure the sports training process of volleyball players.
