This quantitative correlational study examined to what extend personality traits predict organizational citizenship behavior (OCB) among full-time public community college employees. Public community colleges are facing significant challenges in managing ongoing decreases in state appropriations. The construction of human capital theory, the HEXACO personality model and OCB provided the theoretical framework for the study. Human capital theory asserts that individual's intangible assets can guide work behavior in a way that establishes economic value for organizations. Personality traits are a type of intangible asset that guides work behavior, and OCB establishes economic value for organizations. Using this framework, this study examined personality traits as a possible predictor of OCB and consisted of a single research question and hypothesis. Sample consisted of 131 full-time employees at two public community colleges in New Mexico. Data was analyzed using two multiple regressions, and results indicated that personality traits do predict OCB directed toward individuals (adjusted R[superscript 2]=0.116, F(6, 124) =3.833 p<0.005) and OCB directed toward the organization (adjusted R[superscript 2]=0.258, F(6, 121) =8.341 p<0.005). More specifically, emotionality and extraversion statistically significantly predict OCBI and extraversion and conscientiousness statistically significantly predict OCBO. These results lead to the rejection of the null hypothesis and indicated that personality traits impact extra-role behavior among public community college employees. Current data supports prior research and lends to future research that further examines OCB and individual personality traits.
