Self-efficacy: Toward a unifying theory of behavioral change. Psycho- logical Review, 84 191-215. Bandura, A. (1977).

This widely cited article provides an analysis of experimental studies concerning the diverse sources and effects of perceived self-efficacy. The author presents an integrative theoretical framework to explain and predict behavioural changes achieved by different modes of treatment. This theory states that psychological procedures, whatever their form, alter the level and strength of self-efficacy which in turn equips them with competencies, self regulatory capabilities, and resilience that enables them to enhance their well-being and accomplishments.
