Psychometric properties of the Chinese Self-Directed Search (1994 edition)

In this study, we (a) examined the measurement equivalence/invariance (ME/I) of the Chinese Self-Directed Search (SDS; 1994 edition) across gender and geographic regions (Mainland China vs. Hong Kong); (b) assessed the construct validity of the Chinese SDS using [Widaman, 1985] and [Widaman, 1992] MTMM framework; and (c) determined whether vocational interests are measured equivalently by Chinese SDS subtests. Confirmatory factor analyses suggested that males and females from Mainland China and Hong Kong interpreted the instrument in conceptually similar manner. Also, the Chinese SDS demonstrated sound construct validity. However, we found that like-named interests were not measured equivalently by the SDS subtests.     

Measuring parental and family efficacy beliefs of adolescents' parents: Cross‐cultural comparisons in Italy and Portugal

The goal of this study was to examine the psychometric properties of the Perceived Parental Self‐Efficacy (PPSE) and Perceived Family Collective Efficacy (PFCE) revised scales in the Portuguese and Italian contexts. To this aim two studies were conducted: the first reported the exploratory and confirmatory factor analyses with Portuguese samples, whereas the second addressed the cross‐cultural invariance of PPSE and PFCE (Portugal and Italy). Results of the first study showed the appropriate fit of the unifactorial model of both scales to Portuguese data. The invariance analyses performed in the second study attested to the PPSE and PFCE's configural, metric and scalar invariance in both countries. The correlations of PPSE and PFCE with communication, management of conflict and children's school achievement further attested to their construct and practical validity. Thus, PPSE and PFCE proved to be suitable to further use in research and psychological assessment fields.     

Self-Other Differentiation Scale: Dimensionality,IRT Parameterization,and Measurement Invariance

The Self-Other Differentiation Scale (Olver, Aries, &; Batgos, 1989 Olver, R. R., Aries, E., &; Batgos, J. (1989). Self-other differentiation and the mother-child relationship: The effects of sex and birth order. The Journal of Genetic Psychology, 150, 311–321. doi:10.1080/00221325.1989.9914600[Taylor &; Francis Online] , [Google Scholar]) is a self-report instrument assessing the experience of a separate sense of self from others. The authors aimed to examine its dimensionality, reliability, and measurement invariance across gender. It was completed by 348 participants (48% men) from 17 to 30 years old in Study 1, 348 participants (40% men) from 18 to 28 years old in Study 2, and 1,068 participants (49% men) from 17 to 28 years old in Study 3. The results supported the hypothesis of just one factor underlying the scale; they also showed an appropriate internal consistency and a partial measurement invariance across gender. Results also showed evidence for a 10-item version of the scale. Globally, the Self-Other Differentiation Scale can be considered a good scale to assess individual's sense of differentiation of one's own sense of self from others.     

A penalized likelihood method for multi-group structural equation modelling

In the past two decades, statistical modelling with sparsity has become an active research topic in the fields of statistics and machine learning. Recently, Huang, Chen and Weng (2017, Psychometrika, 82, 329) and Jacobucci, Grimm, and McArdle (2016, Structural Equation Modeling: A Multidisciplinary Journal, 23, 555) both proposed sparse estimation methods for structural equation modelling (SEM). These methods, however, are restricted to performing single-group analysis. The aim of the present work is to establish a penalized likelihood (PL) method for multi-group SEM. Our proposed method decomposes each group model parameter into a common reference component and a group-specific increment component. By penalizing the increment components, the heterogeneity of parameter values across the population can be explored since the null group-specific effects are expected to diminish. We developed an expectation-conditional maximization algorithm to optimize the PL criteria. A numerical experiment and a real data example are presented to demonstrate the potential utility of the proposed method.     

SWLS网络测验中可靠性变量的测量不变性检验

测量不变性在自我报告问卷或量表的心理测量应用中非常重要,是跨组比较的前提条件。测量不变性检验模型包括无任何约束的分组验证性因素分析(M_group)、形态的不变性(M1)、负荷的不变性(M2)、截距的不变性(M3)、严格不变性(M4)、因子方差-协方差的不变性(M5)以及潜均值的不变性(M6)。以生活满意度量表(SWLS)为例,针对1343名大学生(年龄17-25岁,20.01±1.53),进行有急事需要处理(否vs.是),答题时感受(积极情绪vs.消极情绪),噪音水平(无噪音vs.有噪音),答题用时(长vs.短),性别(男vs.女),户口(非农业户口vs.农业户口)等不同组别的生活满意度量表(SWLS)完全因素不变性检验。结果表明:(1)是否有急事需要处理的不变性成立(Δχ²=0.49～10.59,p>0.05);(2)答题时感受不变性部分成立,M5、M6模型不变性不成立(Δχ²₍₁=3.96、20.89,p<0.05);(3)噪音水平不变性部分成立,M3与M4模型不变性检验不成立(Δχ²₍₄₎=14.75,Δχ²₍₅₎=23.91,p<0.05);(4)答题用时不变性不成立(Δχ²=11.01～41.95,均p<0.05);(5)性别的不变性部分成立,M4模型不变性检验不成立(Δχ²₍₅₎=64.40,p<0.05);(6)户口的不变性部分成立,M6模型不变性检验不成立(Δχ²₍₁₎=11.49,p<0.05)。     

ITC Guidelines for Translating and Adapting Tests (Second Edition)

The second edition of the International Test Commission Guidelines for Translating and Adapting Tests was prepared between 2005 and 2015 to improve upon the first edition, and to respond to advances in testing technology and practices. The 18 guidelines are organized into six categories to facilitate their use: pre-condition (3), test development (5), confirmation (4), administration (2), scoring and interpretation (2), and documentation (2). For each guideline, an explanation is provided along with suggestions for practice. A checklist is provided to improve the implementation of the guidelines.     

Assessing conspiracist beliefs across societies: Validation of the Serbian adaptation of the Generic Conspiracist Beliefs Scale (GCBS)

Initial validation of the Generic Conspiracist Beliefs Scale (GCBS) identified five correlated factors: Government Malfeasance, Malevolent Global Conspiracies, Extraterrestrial Cover-up, Personal Well-being and Control of Information. Despite replications of this structure, ensuing research, mostly using translated versions of the GCBS (i.e., Persian and Japanese), has reported factorial alternatives. Concomitantly, researchers postulated that belief in conspiracies was higher in historically troubled societies (e.g., Serbia). To further assess the cultural stability of the five correlated factor solution and test the assumption that GCBS scores are affected by social-political instability, a Serbian adaptation of the GCBS was assessed alongside the standard English language version. Data were collected from Serbian (n = 259, 44.40% males) and UK samples (n = 402, 52.25% males). Within samples, confirmatory factor analysis replicated the five-factor solution. Additionally, national and gender invariance was confirmed. National comparisons (Serbia vs. UK) revealed that the Serbian sample scored higher on Government Malfeasance, Malevolent Global Conspiracies, Personal Well-being and Control of Information, whereas the UK sample scored higher on Extraterrestrial Cover-up. There were no gender differences on GCBS factors. Findings indicated that while the Serbian GCBS was interpreted similarly to the GCBS, societal factors influenced endorsement of belief facets.     

Cross-validation of the very short form of the Physical Self-Inventory (PSI-VS): invariance across genders, age groups, ethnicities and weight statuses

In a recent review of various physical self-concept instruments, Marsh and Cheng (in press) noted that the very short 12-item version of the French Physical Self-Inventory (PSI-VS) represents an important contribution to applied research but that further research was needed to investigate the robustness of its psychometric properties in new and diversified samples. The present study was designed to answer these questions based on a sample of 1103 normally achieving French adolescents. The results show that the PSI-VS measurement model is quite robust and fully invariant across subgroups of students formed according to gender, weight, age and ethnicity. The results also confirm the convergent validity and scale score reliability of the PSI-VS subscales.     

Big Five personality dimensions in Italian and Dutch adolescents: A cross-cultural comparison of mean-levels, sex differences, and associations with internalizing symptoms

In the present cross-national comparison, self-reported Big Five personality data on large samples of Dutch (N = 1521) and Italian (N = 1975) adolescents were employed. Results suggest that the personality of Dutch and Italian adolescents can be described by the same Big Five traits, but that these might have slightly different meanings to the Dutch and Italian adolescent respondents. Supplementary analyses uncovered that sex differences are largest among Italian adolescents. Further comparisons reveal subtle cross-national differences in personality-psychopathology relationships, with stronger associations of Emotional Stability with depression for Italian when compared to Dutch adolescents. Results underscore that cross-national comparisons of personality may be alluring to use in research, however the findings of these comparisons should be interpreted with caution.     

A latent variables examination of processing speed, response inhibition, and working memory during typical development

This study addressed three related aims: (a) to replicate and extend previous work regarding the nonunitary nature of processing speed, response inhibition, and working memory during development; (b) to quantify the rate at which processing speed, response inhibition, and working memory develop and the extent to which the development of these latter abilities reflect general changes in processing speed; and (c) to evaluate whether commonly used tasks of processing speed, response inhibition, and working memory are valid and reliable when used with a developmentally diverse group. To address these aims, a latent variables approach was used to analyze data from 147 participants 6-24 years of age. Results showed that processing speed, response inhibition, and working memory were separable abilities and that the extent of this separability was stable across the age range of participants. All three constructs improved as a function of age; however, only the effect of age on working memory remained significant after processing speed was controlled. The psychometric properties of tasks used to assess the constructs were age invariant, thereby validating their use in studies of executive development.
