Criminal justice research employs several methodologies to gather and analyze data. The four primary research methods used in the field are exploratory, descriptive, explanatory, and evaluative. Each method serves a purpose in contributing to the body of knowledge in criminal justice.
Exploratory research is employed when limited information is available about a particular issue, crime trend, or phenomenon. The goal of exploratory research is to investigate new or emerging topics to gain a better understanding and develop hypotheses for further research. Researchers typically use this type of research when they don’t properly understand a problem and they need to gather preliminary data before conducting more in-depth studies.
Explanatory research seeks to explain the causes and effects of criminal behavior, crime trends, or justice system practices. This type of research aims to uncover the root causes of certain phenomena and establish causal relationships. Explanatory research is crucial for identifying the factors that contribute to criminal behavior and for understanding the impact of various justice interventions.
Descriptive research focuses on describing characteristics, behaviors, or trends related to crime, criminal behavior, or a demographic. The goal of descriptive research is to provide a detailed account of a particular phenomenon, such as crime rates in a specific area, offender demographics, or the effectiveness of a new policing strategy.
Evaluative research assesses the effectiveness of programs, policies, or interventions within the criminal justice system. This type of research helps policymakers and practitioners determine whether a particular program or policy is achieving its intended outcomes. Two Examples of evaluative research are policy evaluation and program evaluation.
Policy evaluation assesses the impact of criminal justice policies, such as sentencing reforms, drug policies, or policing strategies. It helps determine whether the policy is effective in reducing crime or achieving other desired outcomes.
Program evaluation focuses on specific programs, such as rehabilitation programs, diversion initiatives, or reentry services. It measures whether the program is successfully meeting its objectives, such as reducing recidivism or improving participant outcomes.
