The purpose of this study was to investigate the structural relationships of personality and life satisfaction with a mediator role of positive and negative affects and life goals. The statistical population of this study is all adults in the 6th district of Tehran in 2016. The sample consisted of 400 adults (25 to 60 years old), residing in Zone 6 in Tehran, that were selected using method multi-stage random sampling. Participants responded to questionnaires of positive and negative affect, life satisfaction, questionnaire Big five Personality Factor and life goals. Data were analyzed by path analysis and LISREL software. Results showed intrinsic goals and positive affect played a mediator role to conscientiousness, extraversion, openness, and agreeableness with life satisfaction, and had a direct effect upon life satisfaction but negative affect and extrinsic goals did not play a mediator role and had no direct effect upon life satisfaction. Also, extraversion and neuroticism had a direct effect on life satisfaction. There was no indirect effect between Neuroticism and life satisfaction and 21 percent variance in life satisfaction is predicted by the model. As a result, it can be argued that attention to intrinsic goals and positive affect are very important in the relationship between personality traits and life satisfaction.
