The study aimed to build a group counseling program in Transcendental Meditation and evaluate its effectiveness in enhancing the level of general psychological adjustment of the female students in the eleventh grade in the governorate of Muscat, Sultanate of Oman, using the semi-empirical method. In order to select the sample of the study, the researcher used the general psychological adjustment scale on the female students of the eleventh grade in the Omama bint Abi Al Salt School for the basic education in the governorate of Muscat. Out of 76 female students, 30 students, who attained the lowest grades in the used scale, were chosen for the study. The sample was randomly divided into two groups; an experimental group of 15 students who were trained on the group counseling program in TM, prepared by the researcher, and a control group of 15 students who did not get any training on the program. The group counseling program included 12 counseling sessions over six weeks (two sessions a week). Each session was 45-60 minutes long. They received also a pre-program, a post-program, and a follow up session. The program was based on the theory of cognitive behavioral therapy and focused on the cognitive behavioral methods.
