Abstract
ObjectivesThe aims of the current study were 2-folded. This study examined the recent meta-analyses in the criminology and criminal justice (CCJ) field to capture a snapshot of the current state of publication bias practices and provided practical guidelines and recommendations on how to address the issues of publication bias in meta-analytic reviews. MethodsThe content analysis reviewed 64 meta-analyses published in top-tier journals in the CCJ field in 2019–2020. The narrative review of previous simulation studies in medical science and psychology fields was performed to synthesize practical guidelines on publication bias in meta-analyses. ResultsRecent CCJ meta-analytic studies have at least partially addressed the issue of publication bias by employing systematic search and statistical methods. However, the current state of CCJ meta-analyses does not meet the expectation required in medical science and psychology that all meta-analytic reviews report the range of effect size estimates across multiple publication bias detection and correction tests. The statistical methods commonly used for assessing publication bias are applied without testing and interpreting assumptions about the missing studies. ConclusionsThere is a need to continue monitoring the quality of meta-analyses to gain a comprehensive picture of how bias leaves a potential imprint in CCJ research.
