Although the strength of method biases may vary across research
contexts, a careful examination of the literature suggests
that common method variance is often a problem and researchers
need to do whatever they can to control for it. As we have
discussed, this requires carefully assessing the research setting to
identify the potential sources of bias and implementing both procedural
and statistical methods of control. Although we clearly
have not resolved all of the issues about this important topic,
hopefully we have provided some useful suggestions and, perhaps
more importantly, a framework that researchers can use when
evaluating the potential biasing effects of method variance in their
research
