The effect of organizational citizenship behavior on public service motivation: A field study

This study examines the relationship between organizational citizenship behavior (OCS) and public service motivation (PSM) among public employees and evaluates whether OCS statistically predicts PSM. OCS refers to voluntary and discretionary behaviors that go beyond formal job requirements and contribute to organizational effectiveness. PSM reflects individuals’ willingness to serve society, protect the public interest, and fulfill social responsibilities. The research was conducted using a quantitative approach, and data were collected from 800 public employees through a structured questionnaire. Descriptive statistics, reliability analysis, correlation analysis, structural equation modeling, and difference tests were employed to analyze the data. The findings revealed a strong, positive, and statistically significant relationship between OCS and PSM. In addition, organizational citizenship behavior was found to be a significant predictor of public service motivation. The results also indicated significant differences across certain demographic variables. Overall, employees reporting higher levels of voluntary and extra-role organizational behavior also reported stronger public service motivation in the study sample.
