Psychological hardiness, a concept developed by Suzanne Kobasa, refers to a personality style that acts as a buffer against the negative effects of stress. It consists of three key attitudes: commitment (feeling involved in life), control (believing one can influence events), and challenge (viewing change as an opportunity for growth rather than a threat).

It has no pharmacological role in the treatment of psychiatric disorders such as schizophrenia.
