In addition, as various areas of research become more sophisticated, we urge care and consideration be taken to develop comparable measures across studies and to work toward understanding the way that timing can change the effect of risk factors on violence. In this book, almost all of the factors we have examined may vary in their effect based on developmental timing, but little consensus would be achieved by reviewing the piecemeal set of studies currently in existence.
Complex Relationships Among Constructs
Complex relationships, such as indirect effects, interactions, nonlinear effects, and reciprocal effects, have been studied across the areas of research we have reviewed in this book. Greater attention should be placed on selecting the most theoretically-relevant complexities and generating multiple tests to provide enough supportive evidence to make findings useful rather than inventing new ones. Only replicated findings are of any real use to further our understanding of phenomena in nonexperimental research.
