This paper examined the relationship between Victor Vroom’s Expectancy Theory of motivation and crime control in the Niger Delta, focusing on selected five states’ police command – Abia, Imo, Edo, Bayelsa, and Delta states out of the nine states of the Niger Delta - Abia, Imo, Cross river, Rivers, Akwa Ibom, Ondo, Edo, Bayelsa, and Delta states. The specific objectives were to: examine whether expectancy have significant relationship with proactive policing, assess whether instrumentality and corruption are correlated, and find out whether there is significant nexus between valence and education. Combination of multi-stage random and purposive sampling procedures were used to select the 1,300 respondents. The collected data were analyzed with the aid of SPSS and hypotheses were tested using Pearson Product Moment Correlation. The results showed that there is significant correlation between Vroom’s expectancy theory of motivation and crime control in the Niger Delta. In the first hypothesis tested, Pearson's r of .852 with p value of .067 indicated that there is a substantial relationship between expectancy and proactive policing. For the second hypothesis, with Pearson's r of .822 with p value of .088, the test validated the hypothesis indicating that there is a strong relationship between instrumentality corruptions. The third hypothesis, with Pearson's r of .243 with p value of .694, the test validated but showing very weak relationship between valence and education. The study concluded that to achieve efficient crime control in the Niger Delta, police authority is expected to; one, enrich the job scope of individual crime fighter and make necessary gadgets needed to enhance the performance of crime fighters available to their personnel, ensure transparency in all that involve motivational package for deserving officer at all time, and provide framework for identification of individual and officers’ values and reward preference in order to define what appeals to individual teammate.
