The Factor Structure of the Frost Multidimensional Perfectionism Scale in University Students

The Frost Multidimensional Perfectionism Scale (FMPS) is a widely used measure of perfectionism. Previous studies of the nature of the factors of the FMPS have resulted in mixed findings and have failed to identify a stable factor structure. This study investigated the factor structure of the FMPS using both exploratory and confirmatory factor analysis (CFA), addressing previous methodological limitations. Participants were 6,449 students from two Australian universities. Exploratory factor analysis suggested a five‐factor model and a reduction in variables from 35 to 29 (FMPS‐29). CFA demonstrated goodness of fit of the revised measure. We also compared our model with a number of existing measurement models of perfection and found the proposed model provided a superior fit for this university student population. Support was found for the two second‐order constructs commonly referred to as adaptive and maladaptive perfectionism, although there appears to be little benefit in using this model over the first‐order model. Implications of the findings are discussed.     

Biased interpretation in perfectionism and its modification

Perfectionism is a transdiagnostic construct associated with a range of diagnoses, including depression, eating disorders and obsessive compulsive disorder. Treatments that directly target perfectionist cognitions have been shown to successfully reduce associated pathologies. However, the way in which they do this is not clear. We set out to assess the role of one candidate mechanism of action, namely the cognitive process of interpretation of ambiguity. In one experiment we looked for associations between biased interpretation and perfectionism. In a second, we manipulated interpretations, thereby providing a strong test of their aetiological significance. Results from the first experiment confirmed the presence of biased interpretation in perfectionism and demonstrated that these are highly specific to perfection relevant information, rather than reflecting general negativity. The second experiment succeeded in manipulating these perfection relevant interpretations and demonstrated that one consequence of doing so is a change in perfectionist behaviour. Together, these data experimentally demonstrate that biased interpretation of perfection relevant ambiguity contributes to the maintenance of perfectionism, but that it is also possible to reverse this. Clinical implications include the identification of one likely mechanism of therapeutic change within existing treatments, as well as identification of an appropriate evidence-based focus for future treatment development. Targeting underlying functional mechanisms, such as biased interpretation, has the potential to offer transdiagnostic benefits.     

早期剥夺所致大鼠抑郁样行为与海马BDNF mRNA表达变化

为探讨早期剥夺对大鼠行为与海马脑源性神经营养因子(BDNF)mRNA表达的影响,将新生的SD大鼠随机分为正常对照组与早期剥夺组,早期剥夺组在出生后1～14d每天孤养4h。监测体重,在出生后36?64天进行液体消耗试验,每周一次。12w龄时,进行穿梭箱试验,酶联免疫法检测海马BDNF含量,原位杂交法观察海马BDNF mRNA的表达。早期剥夺组大鼠体重显著低于正常对照组(p0.01),糖水摄入量与糖水偏爱显著低于正常对照组(p0.05或p0.01)。穿梭箱试验中,早期剥夺组大鼠在训练时的穿梭反应次数显著少于正常对照组(p0.05),在测试时,两组大鼠的被动逃避行为、主动逃避行为与逃避错误次数无显著差异。早期剥夺组大鼠海马BDNF含量、CA1区和CA3区BDNF mRNA表达显著低于正常对照组(p=0.05或p0.05)。提示早期剥夺可导致大鼠生长减慢,表现出快感缺失的抑郁样行为,但未诱导成年大鼠表现出明显的习得性无助倾向,早期剥夺能下调成年大鼠海马BDNFmRNA的表达。     

从EDRF的发现来看科学研究中的偶然性和必然性

本文通过讲述血管内皮舒张因子(endothelium-derived relaxing factor,EDRF)发现过程中的一些事例,讨论科学研究中的偶然性与必然性之间的辩证关系。把握偶然性和必然性之间的对立统一关系,有助于深化对自然和社会规律的认识。科研工作者应运用辩证唯物主义的观点,重视偶然现象,探索必然规律。     

肾移植患者生存质量及影响因素分析

探讨肾移植患者的生存质量及影响因素。采用健康状况调查问卷(SF-36)调查广州地区医疗机构145例肾移植受者移植前和移植后6个月的生存质量。移植后6个月患者的生存质量评分较移植前有明显提高。文化程度、有无配偶、经济状况、肾源、健康知识掌握程度等因素对患者的生存质量影响较大。医护人员应为肾移植患者提供个性化护理,以提高患者的生存质量。     

两水平研究中单维测验信度的估计

在心理、教育和管理等研究领域中,经常会碰到两水平（两层）的数据结构,如学生嵌套在班级中,员工嵌套在企业中。在两水平研究中,被试通常不是独立的,如果直接用单水平信度公式进行估计,会高估测验信度。文献上已有研究讨论如何更准确地估计两水平研究中单维测验的信度。本研究指出了现有的估计公式的不足之处,用两水平验证性因子分析推导出一个新的信度公式,举例演示如何计算,并给出简单的计算程序。     

双因子模型：多维构念测量的新视角

双因子模型是一种既有全局因子又有局部因子的模型,近年来有了许多应用。本文讨论了双因子模型和高阶因子模型在数学模型、参数之间的关系,概念上和应用上的差异;概述了双因子模型在信度研究、平衡量表、探索性因子分析和项目反应理论中的应用。作为例子,在Rosenberg自尊量表结构的研究中,通过双因子模型分析了自尊特质效应与项目表述方法效应。     

建言行为的认知影响因素、理论基础及发生机制

目前关于建言行为的研究大多关注其发生的前因变量, 而探讨其认知发生机制的研究则相对较少。建言行为不论是在行为触发机制、过程决策机制还是建议表达机制等三个方面均与个体的认知活动密切相关。通过梳理影响员工建言行为发生的认知因素, 该文提出员工建言行为认知发生机制全模型, 并对未来的研究方向作出展望。     

共同方法变异的影响及其统计控制途径的模型分析

共同方法变异(common method variance, CMV)指两个变量之间变异的重叠是因为使用同类测量工具而导致, 而不是代表潜在构念之间的真实关系。虽然以往研究显示CMV不一定导致研究结果的偏差, 在实际研究中应当加以考量。特别是在使用测量方法的研究中, 如果数据来源越单一, 测量方法越类似, CMV效应使研究结果产生偏差的可能性越大。CMV效应的控制方法包括过程控制法和统计控制法。在统计控制法的选择和使用上, 需要重点考虑该方法是否分离了三大变异(特质变异、方法变异和误差变异), CMV效应是在测量构念层面还是题目层面, CMV效应是加法效应还是乘法效应。控制潜在方法因子途径是统计控制方法中最重要的一类方法, 理解其模型是正确使用这类方法的前提。未来研究应当关注多个研究的CMV效应和侧重评估某个理论研究中CMV所引起的潜在的效度威胁。     

当代中国青少年理想的现状及影响因素研究

为考察当代中国青少年理想的现状及其影响因素,研究采用当代青少年理想调查问卷对全国12个省份的5000名青少年进行调研,结果发现当代中国青少年的理想水平较高,其中男生在身体理想方面的水平高于女生,在道德、人格、学业、生活和职业等理想方面的水平低于女生;初中生在道德、人格、生活和社会等理想方面的水平高于高中和大学低年级学生,在物质、身体、学业和职业等理想方面的水平低于大学低年级学生,而高中生的学业和职业理想的水平低于初中生和大学低年级学生。回归分析发现,父亲文化程度能够正向预测青少年的职业理想,母亲文化程度对青少年的生活理想有负向预测作用,家庭收入对青少年的物质、生活和身体理想有显著的正向预测作用。
