Ryff's psychological well-being inventory: factorial structure and life history correlates among Japanese university students.

The theoretical model of psychological well-being that encompasses six domains (self-acceptance, positive relations with others, autonomy, environmental mastery, purpose in life, and personal growth) was tested with a Japanese university student population (N = 574) using a Japanese translation of Ryff's 1989 Psychological Well-being Inventory. A factor structure similar to Ryff's original model emerged. Both depression and anxiety correlated only moderately with scores on some subscales of the inventory, suggesting the relative independence of these dimensions of psychological well-being and negative affectivity. With negative affectivity controlled, some early life experiences were significantly linked with psychological well-being: relationships with romantic partners were linked with greater autonomy and experiences which enhance self-esteem were liked with greater personal growth. Careful psychometric work on the Japanese version is required to use the scale; then a replication and extension of the present study would be feasible.
