Another theory of Depression is Julian Rotter’s (1975) concept of locus of control. This refers to the self-belief that you can can affect and alter your situation, which means Rotter terms someone with an internal locus of control and a high sense of self-efficacy. An external locus of control occurs, when people don’t feel in control of their situation and they have a low sense of self-efficacy. Rotter has observed that people with Depression usually have an external locus of control and a low sense of self-esteem.
