The present research was conducted to develop instructional programs of Islamic morals & existential consciousness enhancement & compare their effectiveness on life satisfaction improvement. First of all, for formulating existential program ,different texts were monitored and common concepts among existential theoreticians specially May, Yalom & Frankle were chosen as a basis of the work. Corryís pattern of existential psychotherapy(2005c) was used for various stages of the program. For formulating Islamic morals program, the researcher used jame olsaadat by Naraghy (because of its relatively integrated theory & systematic structure), Javady e Amoly & Motahharysí ideas. The pattern for stages of this program is derived from change stages in Systems of Psychotherapy by Prochaska & Norcross (1994). The participants (45 students from Allameh Tabatabai University, the Faculty of psychology and education) randomly divided into 3 groups: existential, moral & control group. While experimental groups were given their instructional programs(Islamic morals and existential programs), no intervention was used for the control group. The methodology of this research was experimental. Life Satisfaction Scale (SWLS, Diener et al., 1985, with reliability 0/88 in Iran.) was used to measure life satisfaction. The results demonstrates that Islamic morals consciousness enhancement program improved life satisfaction but existential consciousness enhancement program was not effective .There was not any meaningful difference between experimental and Islamic morals group
