The Coopersmith Self-Esteem Inventory (SEI) Japanese Version was used on 1, 455 junior & senior high school students in 1989 to assess its reliability and validity. In intermal consistencies, Cronbach's Alpha of the Inventory and two subscales were acceptable : the Inventory 0.81, General Self Subscale 0.78 and Home-Parents Subscale 0.70. The alpha coef-ficients of the two subscales were low : School-Academic 0.41 and Social Self-Peers 0.29. Test retest reliability of individuals' scores for the SET were calculated for 36 students (14 years old) who took SET twice with an 4-week interval testings. The Inventory and subscales were all in an acceptable range with the Inventory and General Self at 0.89, School-Academic at 0.85, Home-Parents at 0.89, and Social Self-Peers at 0.81. Concerning validity, content and construct validity of the SET were studied. Items of the SET fit the construct definitions, and also there were few culture differences between U.S.A. and Japan. Factor analysis was done and there were seven factors. Two of the factors were supported the subscales, Home-Parents and Social Self-Peers. The relationship of Moos Family Environment Scale and the SET fit the construct of the concept on attitude of parents. The findings show that the Inventory have enough reliability and validity. Hower, it is needed careful attention on the subscales. [J.J.H.E.P, 1995; 2: 3-15]
