Withthe aim of surveying the mediating effects of individual accountability in causal relations among personality traits, stress and job satisfaction, a sample consisting of 250 faculty members in three state universities was chosen using random stratifiedsampling. The data were gathered through NEO big five factor inventories and stress, job satisfaction and individual accountability questionnaires. To evaluate the relations among latent variables, measured in conceptual model, the Structural Equation Modeling was used. The results showed that the personality trait of conscientiousness bears a negative and significant relation with stress, a positive and significant relation with felt accountability, and the personality trait of agreeableness bears a positive and significant relation with satisfaction and a negative and significant relation with accountability. The results also showed that the relation between conscientiousness and job stress is mediated through felt accountability. Meanwhile, the mediating role of the felt accountability in the relation between the personality trait of agreeableness and job satisfaction was not confirmed. In the concerned model all regressive weights except the relation between accountability and job satisfaction were statistically significant. The results put emphasis on the necessity of reassessing the mediating role of felt accountability in surveying the causal relation among personality traits, stress and job satisfaction.
