青少年健康危险行为的潜结构的Taxometric分析

目的:青少年健康相关危险行为会对其当前和今后的生活产生不可预计的影响,探明危险行为的潜在结构属性对其临床诊断和干预有重要的意义。方法:研究样本3226人来自4个不同城市,采用Taxometric分析法中的三种程序(MAMBAC、MAXEIG和L-Mode)对青少年健康相关危险行为问题的潜在结构进行分析。根据直观的图形和客观的CCFI指标对结果进行判定。结果:MAMBAC图形显示结果支持维度结构,而CCFI为0.53,落在模糊区间0.4-0.6内;MAXEIG图形显示支持维度结构,CCFI为0.39,落在模糊区间附近;L-Mode图形支持维度结构,CCFI为0.53,落在模糊区间内。结论:综合3种程序的图形和CCFI指标,青少年健康相关危险行为问题的潜在结构更有可能是维度的而不是类别的

Detecting the latent structure of the adolescent health related risky behavior is important for clinical diagnosis and intervention. Methods： Responses were obtained from a large sample（n=3226; 45.87% girls） unselected with regard to convenience, comprising common junior and senior students from four cities of China. MAXEIG, MAMBAC, and L-Mode were performed with indicator sets drawn from Adolescent Health Related Risky Behavior Inventory. Assessments also included objective Comparison Curve Fit Indices. Results： The plots of the three procedures supported the dimen- sional construct, and the CCFIs of the procedures were 0.53／0.38／0.53 respectively. Conclusion： Results yield converging evidence that adolescent health related risky behavior has a dimensional latent structure

Categorical or Dimensional： A Brief Introduction to Taxometric Techniques

心理结构是间断的类别还是连续的维度一直是心理学界争议的一个重要问题。用于探索变量类别和维度属性的统计方法有多种,其中由Paul Meehl及其同事开创和发展的类别测量学(Taxometric)分析法在精神病理学和人格心理学研究中使用最多。该方法以切点一致动力学(Coherent Cut Kinetics,CCK)为统计基础,是一组包含十多种程序的程序群,文章介绍了几种常用的分析程序(MAMBAC、MAXEIG和LMode)以及使用过程中需要考虑的问题。文章最后对Taxometric分析法的优缺点进行了简要讨论

伴前庭症状的急性轻型卒中患者6个月焦虑抑郁状态影响因素研究 Influencing Factors of Anxiety and Depression State at 6 months after Stroke in Acute Mild Stroke Patients with Vestibular Symptoms

目的 探索性研究伴前庭症状的急性轻型卒中患者卒中后6个月焦虑抑郁状态的危险因素及神经功能恢复情况。 方法 前瞻性连续收集2020年9月—2022年9月首都医科大学附属北京天坛医院神经内科住院患者中伴发前庭症状的急性轻型卒中患者的人口学信息、卒中危险因素、发病前mRS评分、入院时NIHSS评分、卒中类型和部位。评估住院期间及卒中后6个月HAMA和HAMD评分。根据卒中后6个月HAMA和HAMD评估结果将患者分为焦虑抑郁组和非焦虑抑郁组，采用二元logistic回归分析影响患者卒中后6个月焦虑抑郁状态的危险因素，同时随访mRS以评估神经功能恢复情况。 结果 共纳入患者230例，平均年龄（56.2±11.9）岁，全部患者发病6个月均预后良好（mRS评分<2分）。卒中后6个月时30例患者（13.0%）存在焦虑和（或）抑郁状态。二元logistic回归分析结果显示，住院期存在焦虑和（或）抑郁状态（OR 3.734，95%CI 1.659～8.400，P=0.001）是卒中后6个月存在焦虑和（或）抑郁状态的危险因素。 结论 伴前庭症状的急性轻型卒中患者整体神经功能预后良好，住院期间存在焦虑和（或）抑郁状态的患者更易在卒中后6个月继发焦虑和（或）抑郁状态。 Abstract: Objective To explore the risk factors and neurological recovery of anxiety and depression at 6 months after stroke in acute mild stroke patients with vestibular symptoms. Methods This prospective study continuously enrolled inpatients with acute mild stroke with vestibular symptoms in the Department of Neurology of Beijing Tiantan Hospital, Capital Medical University from September 2020 to September 2022. Demographic information, stroke risk factors, pre-stroke mRS Score, NIHSS score, stroke type and location were collected. HAMA and HAMD scores were assessed during hospitalization and 6 months after stroke. Divided the patients into anxiety-depression group and non-anxiety-depression group according to the HAMA and HAMD scores 6 months after stroke. To assess neurological recovery (by follow up mRS) and the risk factors of anxiety and depression 6 months after stroke by binary logistic regression. Results A total of 230 patients were included, with an average age of 56.2±11.9 years old, all patients had good prognosis (mRS score<2). At 6 months after stroke, 30 patients (13.0%) had anxiety and/or depression. The binary logistic regression analysis showed that the presence of anxiety and/or depression during hospitalization (OR 3.734, 95%CI 1.659-8.400, P=0.001) was a risk factor for anxiety and/or depression at 6 months after stroke. Conclusions Although the overall neurological prognosis of acute mild stroke patients with vestibular symptoms was good, patients with anxiety and/or depression during hospitalization are more likely to develop anxiety and/or depression 6 months after stroke
