Resolving conflicts between students and their parents could lead to improvements in academic achievement. As a result, ways of helping with such an outcome are of significance. It can be hypothesized that improvements in moral and spiritual intelligence could lead to such resolutions. To explore this relationship, from among 450 high school students selected randomly, a group of 90 students with high level of parental conflict was identified using a valid instrument. They were assigned to two experimental and one control groups. The experimental groups received 8 weeks of instructions on using their moral and spiritual intelligence. Post-treatment assessments revealed that both experimental groups scored significantly higher than the control group on conflict resolution skills while no difference between the two experimental groups was detected. Thus, it can be concluded that improvements in students’ spiritual/moral intelligences can lead to decrease in their conflicts with their parents.
