Hi Angus --
Might the following be of interest?
MacKinnon, Krull, & Lockwood (2000). Equivalence of the mediation, confounding, and suppression effect. Prevention Science, 1, 173-181.
Abstract: This paper describes the statistical similarities among mediation, confounding, and suppression.
Each is quantified by measuring the change in the relationship between an independent
and a dependent variable after adding a third variable to the analysis. Mediation and confounding
are identical statistically and can be distinguished only on conceptual grounds.
Methods to determine the confidence intervals for confounding and suppression effects are
proposed based on methods developed for mediated effects. Although the statistical estimation
of effects and standard errors is the same, there are important conceptual differences
among the three types of effects.
Good luck,
~Michael

Subject: [OB-LIST] Seeking suggestions for understanding confouding effect and its treatment
Hello all,
I seek your suggestion on understanding and treatments of confounding/confounded effect, especially papers and studies in OB areas, although I have found some useful sources, i.e., Pearl. J. (2000). Causality. Cambridge University Press.
Thank you in advance.
Angus
