GOUVEIA, Valdiney V. et al. Self-report Altruism Scale: evidences of construct validity. Aletheia [online]. 2010, n.33, pp. 30-44. ISSN 1413-0394.

This study aimed to adapt the Self-report Altruism Scale (SAS), providing evidences of its construct validity. Two studies were carried out in João 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 (α = 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 (α = 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.
