Factors Influencing Public Trust in the Police in South Korea: Focus on Instrumental, Expressive, and Normative Models

Abundant studies examining public trust in the police have applied several theoretical models including instrumental, expressive, or normative models. However, few studies have attempted to simultaneously assess the empirical validity of these theoretical models of public trust in the police. In addition, there has been little research on public trust in police in East Asia; most of the empirical research on this topic has been explored in Western societies. To extend the knowledge of public trust in the police, the current study investigated to what extent factors drawn from three models influence public trust in the police using a sample of South Korean citizens. The results show that, consistent with prior research, police effectiveness, procedural justice, and social cohesion had significant, positive effects on public trust in the police. Police effectiveness was the most influential factor followed by procedural justice and social cohesion. Implications for practice and future research are discussed.
