Construct Validity of the Offer Self-Image Questionnaire and Its Relationship with Self-Esteem,Depression, and Ego Development

Construct validity of the Offer Self-Image Questionnaire (OSIQ) was studied in a sample of 194 normal Finnish adolescents from 14 to 16 years of age. Confirmatory factor analysis provided support for the hierarchical structure of adolescents’ self-image with 5 lower-order factors loading on a single higher-order factor. Lower-order factors were Personally Anxious Self, Social Relationships, Sexual Attitudes, Family Relationships, and Social Conscience. The relationships between the self-image areas of the OSIQ, global self-esteem, depression, and ego development were also examined. The results support the construct, convergent, and discriminant validity of the presented structure of the OSIQ.He received M.A. from University of Helsinki.
