Public and Professionals’ Perceptions of Wrongful Convictions in Pakistan: Scale Development and Validation

Abstract

Wrongful convictions (WC) have been widely studied in law and social sciences, yet, previous research lacks a clear conceptualization and rigorous scientific measurement scale to measure stakeholders’ WC perceptions. Given the significance of stakeholders’ perceptions in influencing policy reforms and transforming the criminal justice system, developing such a measurement scale offers an effective tool to comprehensively understand the relationship between WC and criminal justice system errors/misconduct and guide policymaking. In this study, based on samples of multiple stakeholders in Pakistan, we adopted qualitative and quantitative techniques for WC perception scale development and empirical testing. The results indicated that WC in the criminal justice system context consists of six dimensions, including perceptions of errors and misconduct by the police, prosecutor, judiciary, defense attorney, eyewitness, and forensics. The resulting WC perception measurement scale demonstrated an acceptable level of reliability and validity. The WC perception latent construct with the six resultant dimensions was tested with a structural equation model to assess the association of each perceived sub-construct with WC perception. The findings indicated that the legal professionals, policymakers, and the general public tend to believe that the prosecutors’ and police errors and misconduct are the prime reasons for WC in Pakistan. This study also provides theoretical and practical implications for future studies in relevant fields.
