【摘要】：目的评价生活满意度指数A量表(LSIA)在农村自杀未遂和正常对照人群中测量的信度和效度。方法采用序贯抽样方法对山东省蓬莱、滕州、邹城、利津、莒南、宁阳6个县(市)的407例自杀未遂病例和按照性别、年龄、居住地匹配的409名正常对照人群进行问卷调查;采用Cronbach'sα系数、相关系数评价量表的内部一致性信度,采用结构效度、效标效度和区分效度来评价量表的效度。结果 LSIA量表在自杀未遂组和正常对照组人群中的Cronbach'sα系数分别为0.828和0.734,各条目得分与删除此条目后量表得分的相关系数分别为0.134~0.648和0.095~0.524(均P0.05),量表的内部一致性较好;探索性因子分析表明,自杀未遂组提取出对生活的热情、决心与不屈服、愿望与已实现目标的统一、自我评价和心境5个公因子,累积方差解释率为52.89%,正常对照组提取出对生活的热情、决心与不屈服、愿望与已实现目标的统一、自我评价、心境和冷漠消极6个公因子,累积方差解释率为51.45%;LSIA、Beck绝望量表(BHS)、流调中心抑郁水平评定量表(CES-D)总分分别为(12.20±4.86)、(44.85±20.72)、(13.25±16.59)分,LSIA量表总分与BHS、CES-D量表总分均呈负相关(r=-0.720、-0.715,P0.001),量表具有较好的效标效度;自杀未遂组LSIA量表总分为(9.39±4.59)分,低于正常对照组的(15.00±3.23)分,差异有统计学意义(t=20.20,P0.001),量表具有较好的区分效度。结论 LSIA量表在农村自杀未遂研究中具有较好的信度和效度,但个别条目仍需调整。
[Abstract]:Objective to evaluate the reliability and validity of life satisfaction index (LSIA) in rural attempted suicide and normal controls. Methods A total of 407 cases of attempted suicide in 6 counties (cities) of Penglai, Tengzhou, Zoucheng, Lijin, Junan and Ningyang, Shandong Province, and 409 normal controls matched by sex, age and residence were investigated. The internal consistency reliability of the scale was evaluated by Cronbach's 伪 coefficient and correlation coefficient, and the validity of the scale was evaluated by structural validity, standard validity and distinguishing validity. Results the Cronbach's 伪 coefficients of LSIA in the attempted suicide group and the normal control group were 0.828 and 0.734, respectively. The correlation coefficients between the scores of each item and the score of the scale after deleting the item were 0.1340.64 and 0.095 卤0.524 respectively (P0.05), and the internal consistency of the scale was good. Exploratory factor analysis showed that the attempted suicide group extracted five common factors, namely, passion for life, determination and unyielding, unity of desire and achieved goal, self-evaluation and mood state, and the cumulative variance interpretation rate was 52.89%. In the normal control group, six common factors were extracted: passion for life, determination and unyielding, unity of desire and achieved goal, self-evaluation, mood and indifference and negativity. The rate of interpretation of cumulative variance was 51.45; The total scores of (BHS), depression rating scale (CES-D) of LSIA,Beck despair scale were (12.20 卤4.86), () 44.85 卤20.72), (13.25 卤16.59, the total scores of LSIA scale and BHS, were (12.20 卤4.86), (卤20.72), (13.25 卤16.59), respectively. The total score of CES-D scale was negatively correlated (r-0.720 + -0.715 P0.001), and the scale had good validity. The total score of LSIA scale in attempted suicide group was (9.39 卤4.59), which was lower than that in normal control group (15.00 卤3.23). Conclusion LSIA scale has good reliability and validity in the study of attempted suicide in rural areas, but individual items still need to be adjusted.
