The affective organizational commitment refers to the employee's acceptation of values, norms and goals of the organization, his disposition to invest his efforts in benefit of the organization, and his desire to stay in it. The relation of self-concept with behaviour and with professional success has been largely studied. However, the researches relating professional self-concept with organizational commitment are rare. The sample for this research was composed by 170 employees from a public institution with average of 9.71 years (SD = 8.25) working in that organization. The Organizational Commitment Scale of Mowday and cols. was used to evaluate the dependent variable (the alpha in this research was 0.83). For the evaluation of the professional self-concept a factorial scale composed by six factors was used: Autonomy, Achievement, Competence, Health, Security and Work Adjustment. Both instruments were individually applied in the participants' work place. Stepwise multiple regression revealed that Achievement and Competence are predictors of organisational behaviour (R2 = .39) The higher the score on Achievement (( = .59) and Competence (( = .13) the stronger the organisational commitment.
