Relationship between positive self-complexity (P-SC), satisfaction, happiness, and depression was investigated in university students ( N =485). Participants completed a questionnaire on satisfaction, happiness, depression, and P-SC. Covariance structure analysis revealed that P-SC was positively associated with satisfaction and happiness, and satisfaction and happiness were negatively associated with depression. These findings suggest that satisfaction and happiness mediated between P-SC and depression. It is concluded that interventions to increase P-SC might increase satisfaction and happiness, and improve depression among university students.
