Fielding, N. (2010). Mixed Methods Research. International Journal of Social Research, 13 (2), 127 -- 138. In the field of criminal justice and security management, there are a wide variety of techniques used to understand the best approaches for interacting with stakeholders. Fielding (2010) determined that the mixed method approach is the most effective. This is because it is examining different aspects of the problem and conducting a separate study to corroborate key ideas. These insights were used to show the underlying trends inside the U.S. And UK criminal justice systems. As Fielding determined, that both countries are wrestling with similar challenges including: rising criminal / gang related violence, juvenile delinquency and gun related crimes. This is illustrating the challenges impacting the two systems. In the future, these ideas can help to identify the root causes of these problems and the best approach for addressing them. The fact that similarities have been identified, is illustrating how similar problems are affecting developed nations. This provides a foundation for understanding the larger trends inside the field of criminal justice. (Fielding, 2010)

Moreover, Ellicott (2011) determined that the mixed approach is effective in analyzing the problem and corroborating the patterns. In a study that was conducted he was testing victim -- police interactions. These techniques were utilized to support higher procedural collaboration...

To comprehend what was happening, a series of interviews were conducted with 110 people. Their responses were compared with general findings from review different sources. Evidence of this can be seen with Ellicott saying, "Using both quantitative and qualitative methods, this study tested the model in the context of victim -- police interactions. In-depth interviews were conducted with 110 people who had reported a crime (personal or property) to the police in the previous year. Quantitative findings supported the predictions that higher perceived antecedents of procedural justice would be associated with higher perceived legitimacy (obligation to obey the law), outcome fairness, and satisfaction with the contact. Qualitative findings supported these results." (Ellicott, 2011)

In spite of the success from using mixed methods, Gorad (2007) found that the qualitative approach is more effective at uncovering problems. This is because the sample is focused on identifying the issues in real time. While the quantitative method, can offer insights for understanding specific trends and the overall scope of the challenges. A good example of this can be seen with Gorard saying, "Quantitative research propositions, as might be expected, not only concern the importance of experimental trials for establishing the security of causal evidence, but also include some important practical and…
