In studying such a question, scholars typically evaluate the effect of an arrest, compared to some other sanction, on the future criminal behavior of the arrestee. A classic example of meta-analysis in criminology was performed by Wells and Rankin and concerned the relationship between broken homes and delinquency.

In another interrupted time series study, D'Alessio and Stolzenberg investigated the impact of Minnesota sentencing guidelines on jail incarceration. the study. In studying such a relationship, scholars create a summated scale of items that is designed to indirectly measure the concept of impulsivity. to translate good research into quality service provision. Criminal justice scholars may be interested in studying the effects of a mandatory arrest policy (independent variable) on future patterns of domestic violence (dependent variable).
