目的:编制符合我国医疗背景下躯体疾病患者自杀危险因素调查表。方法:通过开放性访谈、查阅文献、专家咨询及小组讨论,确定量表条目85条。在长沙市某三甲医院的住院病人中施测,有效问卷438份。结果:经过探索性因素分析保留条目51条,躯体疾病病人自杀意念危险因素调查表总的Cronbach’sα系数为0.878,各因子的α系数在0.551-0.825之间,各条目的负荷为0.413-0.662。躯体疾病病人自杀危险因素调查表与抑郁自评量表(r=0.729)、焦虑自评量表得分(r=0.548)、自杀意念(r=0.345)呈正相关(P均<0.01)。结论:躯体疾病患者自杀危险因素调查表条目区分度,初步的信、效度符合测量学要求。
OBJECTIVE: To prepare a questionnaire that suits the risk factors of suicide in patients with somatic diseases under medical background in China. Methods: Through the open interviews, access to literature, expert advice and group discussions to determine the amount of items 85 entries. In Changsha, a top three hospital inpatient application, effective questionnaire 438 copies. Results: After 51 items were reserved by exploratory factor analysis, the total Cronbach’sα coefficient of the risk factors for suicide ideation of somatic diseases patients was 0.878, the α coefficient of each factor was between 0.551-0.825, and the load of each item was 0.413-0.662 . There was a positive correlation between risk factors of somatic disease and self-rating depression scale (r = 0.729), self-rating anxiety scale (r = 0.548) and suicidal ideation (r = 0.345) (all P <0.01). Conclusion: The discrimination index of suicide risk factors in patients with somatic diseases is preliminary. The preliminary reliability and validity meet the requirements of surveying.
