【摘要】：目的对失独者抑郁症状进行潜在类别分析,了解失独者抑郁症状的个体差异,以及不同人口学特征对潜在类别的影响。方法采取分层随机整群抽样的方法,于2014年9月—2015年12月对长沙市249例失独者进行抑郁自评量表(SDS)评分,对失独者的抑郁状况进行潜在类别分析。并分析性别、年龄、婚姻状况、家庭所在地对潜在类别的影响。结果共发放问卷249份,剔除30份未作答问卷,回收219份有效问卷,有效回收率为88.0%。本研究探索了1~5个潜在类别模型,随着分类数逐渐增加,AIC、BIC、a BIC不断减少,Entropy在4个类别时已最大,但是LMR不显著,且BIC增大,因此,3个类别的分类模型最为合理,其中C1、C2、C3的类别概率分别为0.428、0.305、0.267。根据C1、C2、C3在SDS 20个条目上的条件概率,将其分别命名为高抑郁组(42.9%)、生理-悲观组(31.5%)、低抑郁乐观组(25.6%)。性别、年龄、婚姻状况对潜在类别的影响,差异均无统计学意义(P0.05);家庭所在地对潜在类别的影响,差异有统计学意义(P0.05)。结论失独者的抑郁症状有明显分类特征,可以分为3个潜在类别,分别为高抑郁、生理-悲观、低抑郁乐观,且家庭所在地可影响潜在类别。
[Abstract]:Objective to analyze the potential categories of depressive symptoms in patients with abstinence and to find out the individual differences of depressive symptoms and the effect of different demographic characteristics on the potential categories. Methods stratified random cluster sampling was used. From September 2014 to December 2015, the self-rating depression scale (SDS) was used to evaluate the depression status of 249 patients in Changsha, and to analyze their depression status, sex, age and marital status. Results 249 questionnaires were sent out, 30 unanswered questionnaires were excluded, 219 valid questionnaires were recovered, and the effective recovery rate was 88.0. In this study, 1 ~ 5 potential category models were explored. With the increasing of the classification number, the Entropy of AICI BICA BIC is the largest in the four categories, but the LMR is not significant, and the BIC increases. Therefore, the classification model of the three categories is the most reasonable. According to the conditional probability of C1C _ 2C _ 3 on 20 items of SDS, it was named as high depression group (42.9%), physiological pessimism group (31.5%), low depression optimistic group (25.66%), sex, age, marriage status influence on potential category. There was no significant difference (P 0.05), and the influence of family location on the potential category was statistically significant (P 0.05). Conclusion the depressive symptoms of the patients with loss of independence can be classified into three potential categories: high depression, physiological pessimism, and so on. Low depression and optimism, and the location of the family can affect the potential category.
