The Relation of Self-Supporting Personality, Big Five Personality and Depression

Self-supporting personality (SSP) is an indigenous Chinese personality concept. It is assumed to be a protective personality factor with regard to depression. In the present study, self-supporting personality traits are assumed to be similar to Big Five personality traits or facets of the Five Factor Model to a considerable degree, but also to contain some tendencies or dispositions which are related to depression in ways that go beyond either the Big Five factors or their sub-factors. The relation of self-supporting personality, Big Five personality, and depression was examined in a sample of 439 Chinese undergraduate students using the Self-Supporting Personality Scale for Adolescent Students (SSPS-AS), the Mandarin Chinese version of Revised NEO Personality Inventory (NEO-PI-R), and the Chinese Version of Self-Rating Depression Scale (SDS). Results from the correlation analysis revealed that most SSP traits were significantly correlated with the Big Five personality dimensions and sub-dimensions, but the correlation between personal flexibility and either the Big Five dimensions or their sub-dimensions were modest at best. Results from the hierarchical linear regression analyses showed that interpersonal responsibility, interpersonal openness, and personal independence negatively predicted depression, even after controlling for demographic variables and the Big Five personality, however, the explained variance decreased sharply. These results support the hypothesis that despite some overlap with the Big Five personality, self-supporting personality is related to depression in additional ways that the Big Five personality dimensions or their sub-dimensions are not.
