Although the relationship between personality characteristics and job performance has aroused significant research interest, there is limited research in the construction context. Thus, the primary focus of this study is to determine whether personality differences exist among the construction professionals. The Turkish version of Gough's Adjective Check List is employed to assess the personality characteristics of construction professionals. Following are only some of the findings derived from the one way ANOVA and independent sample T-test used for the analysis: Architects tend to score higher on the scales of aggression, change, and creative personality than do civil engineers; whereas civil engineers have higher scores on the scales of order, endurance, interception, nurturable, affiliation, personal adjustment, military leadership, and feminine attributes than architects. When it comes to gender, counseling readiness, along with autonomy, become two of the most differentiating factors between males and females. The findings of this study reveal that similarities and differences do exist among architects and civil engineers, males and females, and various age groups and should be managed accordingly for the ultimate success in the construction profession.
