Contribution Behavior in Virtual Communities: Cogntiive, Emotional, and Social Influences

We examined the robustness of the results with four approaches. First, as Podsakoff et al. (2003) recommend, we employed Harman’s onefactor test. This test assesses the threat of common method bias by indicating whether a single latent factor offers a viable alternative explanation of the analysis. The one-factor latent model yielded a chi-square of 6063.27 (d.f. = 209). The fit of the one-factor model was significantly worse than that of the measurement model. Therefore, we gained preliminary evidence that the measurement model was robust to common method variance.
