This study used path-analysis to examine the assumption that the presence of mental pain in adults mediates the relationship between self-destruction, number of losses experienced in one's life, and suicidal tendency.
Fifty suicidal inpatients, 50 non-suicidal inpatients and 50 healthy volunteers were assessed for self-destruction, losses experienced, depression, suicidal tendency, and mental pain.
Self-destruction was found to have both a direct effect on suicidal tendency as well as one mediated by the presence of mental pain. Number of losses effected suicidal tendency only indirectly, mediated by the presence of mental pain. Overall, self-destruction was a more significant determinant of suicidal tendency than were the number of losses experienced during one's life. A competing model, with depression replacing mental pain as the mediator, was also found to fit the data.
These findings provide evidence that the presence of mental pain is a mediator in the relationships between both self-destruction and number of losses experienced, and between suicidal tendencies. More studies are needed in order to further differentiate between mental pain and depression as mediators in suicidal tendency.
本研究采用路径分析来检验一种假设，即成年人心理痛苦的存在介导了自我毁灭、一生中经历的损失数量与自杀倾向之间的关系。
对50名有自杀倾向的住院患者、50名无自杀倾向的住院患者和50名健康志愿者进行自我毁灭、经历的损失、抑郁、自杀倾向和心理痛苦的评估。
发现自我毁灭对自杀倾向既有直接影响，也有通过心理痛苦的存在介导的影响。损失数量仅通过心理痛苦的存在间接影响自杀倾向。总体而言，自我毁灭比一生中经历的损失数量更能显著决定自杀倾向。还发现一个竞争模型，即由抑郁取代心理痛苦作为中介，也符合数据。
这些发现提供了证据，表明心理痛苦的存在是自我毁灭与经历的损失数量之间以及自杀倾向之间关系的中介。为了进一步区分心理痛苦和抑郁作为自杀倾向中介的差异，还需要更多研究。
