Methods： A questionnaire survey was conducted in the test group （n = 98） by filling out a symptom checklist 90 （SCL-90）. And then the survey result was compared with the normal group （n = 1388） contained in relevant references. Results： Except for hostile factor that was similar to normal level （P 〉 0.05）, other 8 factors were higher than in normal group （P 〈 0.01）. And the cancer patients were classified with the survey results. Conclusion： Compared with normal persons, cancer patients have more psychological problems and related intervention measures are sought necessarily to improve the quality of life, to advance the immune function and to prolong the survival time of patients.展开更多

To fulfil the stated goal 993 individuals were selected by means of stratified sampling procedures and the following measures were distributed among them： Muslim-Spiritual Attachment Scale, Kin Altruism, Reciprocal Altruism Enright Forgiveness Inventory, and Symptom Checklist-90 Revised. Analysis of data using t test revealed significant differences between male and female students （/9 〈 0.01）. Moreover, data indicated that interpersonal sensitivity was higher in male students while somatization complains was higher among female students. Analysis of data showed that quality of secure attachment in female students were higher than male students （P 〈 0.01）. Moreover, female students were higher in altruism, especially in domain of compassion （P 〈 0.05）. In addition female students were higher in perceiving God as a Safe Haven and providing them with comfort and tranquility. Moreover, females students were higher in altruism （p 〈 0.05）, and forgiveness （p 〈 0.01）. The analysis of data revealed that female students were higher in the secure attachment to God, sympathy toward others and they scored higher in somatization complain while male students were higher in the interpersonal sensitivity. Theoretical implication and practical application of findings have been discussed in the original paper. Findings in this project were consistent with body of research findings. Theoretical implication and practical usage of the current study was described in the original paper. Data revealed that female student were higher in secure attachment to God, altruism and forgiveness. Showing emotional stability and higher spirituality.展开更多
