摘要：Este artigo objetivou adaptar a Escala de Altruismo Autoinformado (EAA), reunindo evidencias de sua validade de construto. Realizaram-se dois estudos em Joao Pessoa (PB), nos quais os participantes responderam a EAA e perguntas demograficas. No Estudo 1 participaram 331estudantes universitarios com idade media de 20. Por meio de analise fatorial exploratoria identificou-se um fator geral de altruismo com 17 itens, explicando 29% da variancia total (a= 0,85; homogeneidade media = 0,29). No Estudo 2 participaram 408 estudantes universitarios com idade media de 22 anos. Realizou-se uma analise fatorial confirmatoria com os 17 itens saturando em um fator (a = 0,83; homogeneidade media de 0,28), observando-se indicadores de ajuste que confirmaram esta estrutura (GFI = 0,92, RMSEA = 0,058). Comprovou-se que as estruturas fatoriais e os coeficientes de consistencia interna foram invariantes atraves dos estudos, concluindo-se que existem evidencias de validade de construto da EAA.
其他摘要：This study aimed to adapt the Self-report Altruism Scale (SAS), providing evidences of its construct validity. Two studies were carried out in Joao Pessoa (PB), with participants having answered the SAS and demographic questions. In Study 1 participants were 331 undergraduate students with mean age of 20. A general factor of altruism, with 17 items, was identified by exploratory factor analysis, accounting for 29% of the total variance (a= 0.85; average homogeneity = 0.29). In Study 2 participants were 408 undergraduate students with mean age of 22. A confirmatory factor analysis was performed with 17 items loading on a single factor (¿ = 0.83; average homogeneity = 0.28), having been observed fit indices that confirmed this structure (GFI = 0.92, RMSEA = 0.058). Moreover, it was observed that the factorial structure and reliability coefficients were invariant across studies. In conclusion, there are evidences of construct validity of the SAS.
