Other studies provided programs to improve self-esteem for grade 6-7 school children. McVey and colleagues evaluated the improvement of self-esteem in grade 6 school children in a school-based program; the program included media influences, enhancing self-esteem and body image, body size
acceptance, healthy living, stress management and positive relationships. The program was offered for 50 minutes with a total of 6 sessions and it improved the self-esteem when the program was completed. Lai and colleagues [17] provided a self-esteem program to grade 7 junior high schools and compared the effect of the program on self-esteem with the control group. The experimental group received a 32-week self-esteem program which consisted of 3 sessions per week. The total score of self-esteem was 3.53 in the experimental group and 3.45 in the control group, measured in the form of a 5-point scale. The self-esteem in the experimental group was significantly higher than that in the control group. Previous studies investigating the effects of self-esteem programs for senior elementary school students or junior high school students (grade 6-7) also showed a significant improvement in the self-esteem of students.
