Aims: The current research was conducted by the aim of investigating the effectiveness of intervention based on psychological capital on hope, optimism, resilience, and self-efficacy among patients with depression.

The experiment group received the intervention based on psychological capital (Lutthans, Youssef, and Avolio, 2007) in eight 90-minute sessions in group. To analyze the data, univariate analysis of covariance and multivariate analysis of covariance were used. Results: Results indicated that the intervention based on psychological capital was effective on improving psychological capital and the components of hope, optimism, resilience and self-efficacy in depressive patients. Moreover, the training intervention was positively effective on reducing the depression level of patients (p< 0/01). Conclusions: The intervention based on psychological capital can be used as an effective method to increase the potency of hope, self-efficacy, resilience and optimism, and to reduce depressive symptoms in patients with depression.
