The statistical significance of the indirect effect of OC
on project performance through innovativeness was tested
using a bootstrapping procedure with 1000 bootstraps.
Compared to common techniques such as the three-step
procedure of Baron and Kenny (1986) or the Sobel test, the
bootstrapping procedure has been used more recently (e.g.,
Bisbe and Malagueˇno, 2012; Hall, 2011) and is suggested
to be more appropriate for small samples not following a multivariate normal distribution, like the sample in this
study (e.g., Preacher and Hayes, 2004, 2008; MacKinnon
et al., 2004)
