October 2005 283Commentaryco n tR i b u t i o n sInterpreting the Results from Multiple Regression and Stru tural Equation ModelsThe coefficients that are associated with pathways in multiple regression, as well as more advanced methods based on regression, such as Structural equa-tion models, are central to the interpretations made by researchers. The complex of factors that influence these coefficients make interpretations tricky and nonintuitive at times. Very often, inappropriate infer-ences are made for a variety of reasons. In this pa-per we discuss several important issues that relate to the interpretation of regression and path coefficients.
