Desenvolvimento, validação e reprodutibilidade de questionário sobre perda de peso

Já está disponível um dos artigos que é resultado do mestrado do Guilherme Artioli. Nesse artigo, mostramos o processo de desenvolvimento, validação e a reprodutibilidade de questionário sobre práticas de perda de peso para atletas de judô. Um aspecto importante desse trabalho é o estabelecimento de um sistema de pontuação para quantificar a gravidade e severidade do processo de perda de peso em atletas de judô.
Outros artigos liderados pelo Guilherme virão. O próximo a sair deve ser um sobre a prevalência, métodos e magnitude da perda de peso em atletas de judô.

The aim of this study was to develop a questionnaire to evaluate rapid weight loss patterns of competitive judo players and to assess its validity and reliability. We evaluated the reliability (n=94), content validity (evaluation by 10 experts), discriminant validity (differences in scores between athletes with body weight below and above their weight class; n=100) and convergent validity (correlation with Restraint Scale; n=60). No item was considered unclear or ambiguous by more than 20% of the experts. The intraclass Coefficient Correlation was above 0.90 for all questions whose answers were parametric (P<0.001; n="94)" n="94">80%; Spearman's Correlation between the Restraint Scale and the Rapid Weight Loss Questionnaire was 0.62 (P<0.001; n=60). Athletes below their weight class (n=50) had a significantly lower score compared with athletes above the weight class (n=50; P<0.001 - Mann-Whitney U test). In conclusion, the questionnaire showed good validity and reliability and could be used accurately to assess weight loss patterns of judo players.
