Previous issue date: 2016-06-17 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / Currently, a great part of researchers and applied sport psychology professionals have been showing an increased interest in adaptive processes presented by the athletes. This study aimed to develop the second version of Adaptive Efficacy Scale for Athletes (EDAO-AR-A), which evaluates the effectiveness of athletes? adaptation facing different sectors of the personality: Affective-Relational (A-R) and Productivity (Pr), as well as assessing its psychometric properties. The research developed in two steps: 1) theoretical stage: analysis of the original version, construction of new items; content analysis by independent judges (n = 4); and semantic analysis; and 2) empirical stage: evaluation of internal structure, accuracy of the parameters of the items and participants? characteristics, convergent/criterion validity evidence and establishing standards. And so, the research included two samples: sample 1, which was composed of 15 athletes (22.93 ? 4.74; 60% women), and sample 2, which was composed by 374 athletes (22.8 ? 7.7; 53.2% men). Instruments used: EDAO-AR-A, Coping Inventory for Athletes in Competition (ICASC-40), Sports Motivation Scale (EMS-28) and Group Environment Questionnaire (GEQ). Different statistical procedures were employed in order to reach the stipulated goals: content validity coefficient (CVC) in order to assess the agreement among the judges; Parallel Exploratory Analysis and Exploratory Structural Equation Modeling (ESEM) for the internal structure evaluation. Categorical version of Cronbach's alpha coefficient estimate of accuracy; Partial credit model (PCM) for parameters estimation of the items, participants? characteristics, as well as setting standards with reference regarding the items; Pearson's correlation for the convergent/divergent validity evidence, and inference analysis ANOVA and MANOVA for the study of criterion validity. The results obtained in step 1 indicated suitability of items that made up the scale (CVC > 0.75) and intelligibility of the participants. The results obtained in step 2 demonstrated both subscales, A-R and Pr, evaluate the effectiveness of adaptation according to three factors: Focus on me, Focus on others and Focus on Problem Situation, with desirable accuracy and invariant factorial structure between men and women. The PCM revealed items with low effort for the studied sample and appropriate adjustments (Infit/Outfit). Correlations indicated significant associations between the variables studied, substantiating the theoretical perspectives. Analyses of variance indicated the scale?s sensibility in capturing differences between groups. Lastly, the standards were established based on the procedure of converting the total score in theta, which will allow the practical application of the obtained results. It is concluded that the second version of EDAO-air is a suitable measure of Adaptive efficacy in athletes, as the results corroborate with theoretical assumptions. Based on the limitations of this research, new studies are suggested. / Atualmente observa-se um crescente interesse por parte dos pesquisadores e profissionais pr?ticos da psicologia do esporte em rela??o aos processos adaptativos apresentados pelos atletas. Este estudo teve como objetivo desenvolver a segunda vers?o da Escala Diagn?stica Adaptativa para Atletas (EDAO-AR-A), que avalia a efic?cia da adapta??o de atletas frente aos diferentes setores da personalidade: Afetivo-Relacional (A-R) e Produtividade (Pr), bem como avaliar suas propriedades psicom?tricas. A pesquisa se desenvolveu em duas etapas: 1) etapa te?rica: an?lise da vers?o original, constru??o de novos itens; an?lise de conte?do por ju?zes independentes (n= 4); e an?lise sem?ntica; e 2) etapa emp?rica: avalia??o da estrutura interna, precis?o, dos par?metros dos itens e caracter?sticas dos participantes, de evid?ncias de validade convergente/divergente, crit?rio e estabelecimento de normas. Para tanto, a pesquisa contou com duas amostras: amostra 1, que foi composta por 15 atletas (22,93?4,74; 60% mulheres), e amostra 2, que foi composta por 374 atletas (22,8?7,7; 53,2% homens). Instrumentos utilizados: EDAO-AR-A, Invent?rio de Coping para Atletas em Situa??o de Competi??o (ICASC?40), Escala de motiva??o esportiva (EMS-28) e Question?rio de Ambiente de Grupo (GEQ). Diferentes procedimentos estat?sticos foram empregados tendo em vista cada um dos objetivos estipulados: coeficiente de validade de conte?do (CVC) para a avalia??o do acordo entre os ju?zes; a An?lise Paralela e Exploratory Structural Equation Modeling (ESEM) para avali??o da estrutura interna. Vers?o categ?rica do coeficiente alfa de Cronbach para estimativa da precis?o; Modelo de cr?ditos parciais (MCP) para estimativa dos par?metros dos itens, caracter?sticas dos participantes, bem como para estabelecimento de normas com refer?ncia nos itens; Correla??o de Pearson para estimativa de evid?ncias de validade convergente/divergente, e an?lises inferenciais MANOVA e ANOVA para evid?ncia de validade de crit?rio. Os resultados obtidos na etapa 1 indicaram adequa??o dos itens que compuseram a escala (CVC> 0,75) e inteligibilidade dos participantes. Os resultados obtidos na etapa 2 demonstram ambas as subescalas, A-R e Pr, avaliam a efic?cia de adapta??o de acordo com tr?s fatores: Foco no eu, Foco no outro e Foco na situa??o problema, com ?ndices desej?veis de precis?o e estrutura fatorial invariante entre homens e mulheres. O MCP revelou itens com dificuldade baixa para amostra estudada e ?ndices de ajustes adequados (Infit/Outfit). As correla??es indicaram associa??es significativas entre as vari?veis estudadas, corroborando com as perspectivas te?ricas. As an?lises de vari?ncia indicaram a sensibilidade da escala em captar diferen?as entre grupos. Por fim, foram estabelecidas as normas com base no procedimento de transforma??o da pontua??o total em theta, o que possibilitar? a aplica??o pr?tica dos resultados obtidos. Conclui-se que a segunda vers?o da EDAO-AR-A ? uma medida adequada da efic?cia adaptativa em atletas, uma vez que os resultados corroboram as hip?teses te?ricas. Com base nas limita??es da pesquisa novos estudos s?o sugeridos.
