Abstract
In many emerging democracies, oversight institutions such as Kenya's Independent Policing Oversight Authority (IPOA) struggle to maintain victims’ trust, legitimacy, and support of IPOA, particularly among victims of police misconduct. These victims often desire fair treatment that respects their dignity, ensures neutrality, and amplifies their voices in the process. A promising strategy to address these challenges is reassurance callbacks. By contacting victims of police misconduct and providing transparent, respectful communication, reassurance callbacks aim to restore trust and enhance the victims' confidence in IPOA's handling of their cases. This pilot will employ a mixed-methods design to preliminarily test the effectiveness of callbacks, focusing on their impact on the victim’s trust, legitimacy, and support of IPOA. After conducting a baseline survey, the ensuing intervention will be administered by IPOA officers who will follow structured protocols when making voice and video callback contacts. After the callbacks, a two-week survey will be used to collect both quantitative and qualitative data on victims’ perceptions of the key study’s outcomes. This pilot will contribute conceptually by expanding the application of the Procedural Justice Theory to the police oversight context—an area that remains under-researched globally. By testing different versions of the reassurance callbacks, the pilot will provide essential data on the feasibility and initial effects of reassurance callbacks, which will be crucial for designing a subsequent full-scale Randomized Controlled Trial (RCT). This larger RCT will rigorously evaluate the long-term impacts of callbacks and inform policy recommendations to optimize procedural justice protocols. The pilot findings will be disseminated to IPOA to inform callback protocol adjustments.

Primary Outcomes

Primary Outcomes (end points)
The project’s overall outcomes will include the victim’s satisfaction, trust, confidence, legitimacy and support. Items of victim’s satisfaction will consist of satisfaction with the process and outcome of the report. Trust indicators will comprise trust in procedural justice, trust in IPOA’s effectiveness and responsiveness to victims’ concerns, a new indicator that we will pilot. For legitimacy, several items will be combined, that is, moral alignment, the necessity of IPOA and perceived legality of IPOA and a new indicator, the ability of IPOA to deliver justice and hold police accountable. Indicators of support will include cooperation in reporting a complaint, cooperation in investigations, and willingness to empower IPOA to discharge its mandate. We will pilot both existing and new measures by combining survey data with interview data to understand which survey-based measures most accurately reflect respondents’ attitudes.
