疼痛的心理学研究

心理学对疼痛的研究已经进行了几十年,成果颇丰。众多的研究已经证实了疼痛与基本心理过程之间的相互关系,包括注意、情绪、动机和记忆。除了基本心理过程外,社会因素也能够调节疼痛,如社会排斥、信仰、音乐、虚拟情境、金钱和权利等。已有疼痛研究中的疼痛测量方法过于主观,并且疼痛调节因素在临床中缺乏实践价值。当前疼痛研究呈现与具身思潮相结合的趋势,未来应更加重视发掘调节疼痛的社会因素。     

Consumer susceptibility to interpersonal influence in Mainland China

To validate the consumer susceptibility to interpersonal influence (SUSCEP) scale in China, questionnaires were administered to 1114 adult employees and 350 university students. Confirmatory factor analyses showed that the consumer susceptibility to interpersonal influence scale had a stable three‐factor structure (i.e. the utilitarian, value‐expressive, and informational dimensions) in both samples, while the original two‐factor structure could not be retrieved. Using Chinese samples, the consumer susceptibility to interpersonal influence scale and its three sub‐scales demonstrated acceptable internal reliability, as well as convergent and discriminant validity. Positive correlations between the consumer susceptibility to interpersonal influence scale (as well as its sub‐scales) and attention to social comparison information also indicated good convergent validity. The distinction between utilitarian dimension and value‐expression dimension in Chinese samples as well as the non‐significant correlations of the utilitarian dimension with self‐esteem and the informational dimension with self‐esteem revealed cultural differences between the East and the West.     

单维项目因素分析：CCFA与IRT估计方法的比较

当观测指标变量为二分分类数据时,传统的因素分析方法不再适用。作者简要回顾了SEM框架下的分类数据因素分析模型和IRT框架下的测验题目和潜在能力的关系模型,并对两种框架下主要采用的参数估计方法进行了总结。通过两个模拟研究,比较了SEM框架下GLSc和MGLSc估计方法与IRT框架下MML/EM估计方法的差异。研究结果表明：（1）三种方法中,GLSc得到参数估计的偏差最大,MGLSc和MML/EM估计方法相差不大;（2）随着样本量增大,各种项目参数估计的精度均提高;（3）项目因素载荷和难度估计的精度受测验长度的影响;（4）项目因素载荷和区分度估计的精度受总体因素载荷（区分度）高低的影响;（5）测验项目中阈值的分布会影响参数估计的精度,其中受影响最大的是项目区分度。（6）总体来看,SEM框架下的项目参数估计精度较IRT框架下项目参数估计的精度高。此外,文章还将两种方法在实际应用中应该注意的问题提供了一些建议。     

Psychometric properties and construct validity of the Muscle Appearance Satisfaction Scale among Hungarian men

Limited studies have evaluated the psychometric properties of the Muscle Appearance Satisfaction Scale (MASS), a measure of muscle dysmorphia, in different cultures and languages. The aims were to examine the psychometric properties of the Hungarian version of the MASS (MASS-HU), and to investigate its relationship with self-esteem and exercise-related variables. Two independent samples of male weight lifters (ns = 289 and 43), and a sample of undergraduates (n = 240) completed the MASS, Eating Disorder Inventory, and Rosenberg Self-esteem Scale. Exploratory factor analysis supported the original five-factor structure of the MASS only in the weight lifter sample. The MASS-HU had excellent scale score reliability and good test-retest reliability. The construct validity of the MASS-HU was tested with multivariate regression analyses which indicated an inverse relationship between self-esteem and muscle dysmorphia. The 18-item MASS-HU was found to be a useful measure for the assessment of muscle dysmorphia among male weight lifters.     

心理健康素质测评系统·中国成年人人际健康素质量表的编制

在文献分析和专家评定的基础之上,构建了人际健康素质的基本结构,并编制了初始的中国成年人人际健康素质问卷。然后通过项目区分度分析和验证性因素分析对初始问卷进行了修订,最终形成了包括合群性、亲仁性、利他性、共情性和友善性5个维度的正式量表。结果表明,人际健康素质量表具有较高的内部一致性信度、重测信度和分半信度以及较好的内容效度、结构效度、校标关联效度和会聚效度。结论：人际健康素质量表具有较好的心理测量学特征,可以作为中国成年人人际健康素质的心理测量工具。     

Some Results on Mean Square Error for Factor Score Prediction

For the confirmatory factor model a series of inequalities is given with respect to the mean square error (MSE) of three main factor score predictors. The eigenvalues of these MSE matrices are a monotonic function of the eigenvalues of the matrix Γ _p = Φ ^1/2 Λ _p ′Ψ _p ⁻¹ Λ _p Φ ^1/2. This matrix increases with the number of observable variables p. A necessary and sufficient condition for mean square convergence of predictors is divergence of the smallest eigenvalue of Γ _p or, equivalently, divergence of signal-to-noise (Schneeweiss & Mathes, 1995). The same condition is necessary and sufficient for convergence to zero of the positive definite MSE differences of factor predictors, convergence to zero of the distance between factor predictors, and convergence to the unit value of the relative efficiencies of predictors. Various illustrations and examples of the convergence are given as well as explicit recommendations on the problem of choosing between the three main factor score predictors. The author is obliged to Maarten Speekenbrink and Peter van Rijn for their assistance with plotting the figures. In addition, I am obliged to the referees for their stimulating remarks.     

Implications of Indeterminate Factor-Error Covariances for Factor Construction, Prediction, and Determinacy

The assumptions of the model for factor analysis do not exclude a class of indeterminate covariances between factors and error variables (Grayson, 2003). The construction of all factors of the model for factor analysis is generalized to incorporate indeterminate factor-error covariances. A necessary and sufficient condition is given for indeterminate factor-error covariances to be arbitrarily small, for mean square convergence of the regression predictor of factor scores, and for the existence of a unique determinate factor and error variable. The determinate factor and error variable are uncorrelated and satisfy the defining assumptions of factor analysis. Several examples are given to illustrate the results.

Configural instability of data from the Life Orientation Test—Revised

Scores obtained with the Revised Life Orientation Test (LOT-R) are commonly interpreted according to the optimism–pessimism factorial model. Positive items would measure individual differences in positive outcome expectancy, and negative items would measure differences in negative outcome expectancy. Configural stability was assessed using four datasets from French adults, N₁ = 429, N₂ = 278, N₃ = 468, and N₄ = 909. Two times out of four the third positive item-variable could also be regressed on the pessimism factor, with a significant improvement of the goodness of fit. Moreover, the semantic content of the best items reveals that the positive vs. negative outcome expectancy interpretation of the factors was not self-consistent. Practical consequences for the use of the usual optimism composite score are discussed.
