Problems with Rationales for Parceling that Fail to Consider Parcel-Allocation Variability

In structural equation modeling applications, parcels—averages or sums of subsets of item scores—are often used as indicators of latent constructs. Parcel-allocation variability (PAV) is variability in results that arises within sample across alternative item-to-parcel allocations. PAV can manifest in all results of a parcel-level model (e.g., model fit, parameter estimates, standard errors, and inferential decisions). It is a source of uncertainty in parcel-level model results that can be investigated, reported, and accounted for. Failing to do so raises representativeness and replicability concerns. However, in recent methodological literature (Cole, Perkins, &; Zelkowitz, 2016 Cole, D. A., Perkins, C. E., &; Zelkowitz, R. L. (2016). Impact of homogeneous and heterogeneous parceling strategies when latent variables represent multidimensional constructs. Psychological Methods, 21(2), 164–174. doi: 10.1037/met0000047[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]; Little, Rhemtulla, Gibson, &; Shoemann, 2013 Little, T. D., Rhemtulla, M., Gibson, K., &; Schoemann, A. M. (2013). Why the items versus parcels controversy needn't be one. Psychological Methods, 18(3), 285–300. doi: 10.1037/a0033266[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]; Marsh, Ludtke, Nagengast, Morin, &; von Davier, 2013 Marsh, H. W., Lüdtke, O., Nagengast, B., Morin, A., &; von Davier, M. (2013). Why item parcels are (almost) never appropriate: Two wrongs do not make a right—camouflaging misspecification with item parcels in CFA models. Psychological Methods, 18(3), 257–284. doi: 10.1037/a0032773[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]; Rhemtulla, 2016 Rhemtulla, M. (2016). Population performance of SEM parceling strategies under measurement and structural model misspecification. Psychological Methods, 21(3), 348–368. doi: 10.1037/met0000072[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) parceling has been justified and recommended in several situations without quantifying or accounting for PAV. In this article, we explain and demonstrate problems with these rationales. Overall, we find that: (1) using a purposive parceling algorithm for a multidimensional construct does not avoid PAV; (2) passing a test of unidimensionality of the item-level model need not avoid PAV; and (3) a desire to improve power for detecting structural misspecification does not warrant parceling without addressing PAV; we show how to simultaneously avoid PAV and obtain even higher power by comparing item-level models differing in structural constraints. Implications for practice are discussed.     

Psychological Trait Resilience Within Ecological Systems Theory: The Resilient Systems Scales

This project describes the development of the Resilient Systems Scales, created to address conceptual and methodological ambiguities in assessing the ecological systems model of resilience. Across a number of samples (total N = 986), our findings suggest that the Resilient Systems Scales show equivalence to a previously reported assessment (Maltby, Day, &; Hall, 2015 Maltby, J., Day, L., &; Hall, S. (2015). Refining trait resilience: Identifying engineering, ecological, and adaptive facets from extant measures of resilience. PLoS ONE, 10(7), e0131826. doi:10.1371/journal.pone.0131826[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) in demonstrating the same factor structure, adequate intercorrelation between the 2 measures of resilience, and equivalent associations with personality and well-being. The findings also suggest that the Resilient Systems Scales demonstrate adequate test–retest reliability, compare well with other extant measures of resilience in predicting well-being, and map, to varying degrees, onto positive expression of several cognitive, social, and emotional traits. The findings suggest that the new measure can be used alongside existing measures of resilience, or singly, to assess positive life outcomes within psychology research.     

Assessing Private and Public Need for Uniqueness: Validation of French Versions of the Need for Uniqueness (NfU) and Self-Attributed Need for Uniqueness (SANU) Scales

Need for uniqueness represents the need for people to feel different and distinguish themselves from others. Two major scales exist that measure this need: the Need for Uniqueness scale (NfU; Snyder &; Fromkin, 1977 Snyder, C. R., &; Fromkin, H. L. (1977). Abnormality as a positive characteristic: The development and validation of a scale measuring need for uniqueness. Journal of Abnormal Psychology, 86, 518–527. https://doi.org/10.1037/0021-843X.86.5.518[Crossref], [Web of Science ®] , [Google Scholar]) and the Self-Attributed Need for Uniqueness scale (SANU; Lynn &; Harris, 1997b Lynn, M., &; Harris, J. (1997b). Individual differences in the pursuit of self-uniqueness through consumption. Journal of Applied Social Psychology, 27, 1861–1883. https://doi.org/10.1111/j.1559-1816.1997.tb01629.x[Crossref], [Web of Science ®] , [Google Scholar]). We propose here a French version of both scales. Through a dual approach of exploratory and confirmatory factorial analyses, we investigated the scales' structure in student samples from two French-speaking countries (France and Switzerland, N = 1,348) as well as measures of internal and external validity. Both scales presented good psychometric properties in French. Additionally, we investigated differences between the scales, as literature suggests that the NfU relies mostly on public and risky displays of uniqueness, whereas the SANU focuses on private and more socially acceptable means to acquire a feeling of uniqueness. Differences arose in the links with several personality characteristics (emotionality, extraversion, agreeableness, sensation seeking, and self-consciousness), suggesting that the NfU corresponds rather to a need to demonstrate uniqueness through public displays and the SANU to a need to feel unique through more private means. We discuss implications for research and provide advice on choosing by the scale most appropriate to the researcher's aims.     

Reciprocal altruism: It’s relationship to locus of control and dispositional optimism among Nigerian undergraduates

The study examined locus of control and dispositional optimism influences on reciprocal altruism among Nigerian university undergraduate students. Participants consisted of 253 undergraduate students in their second year of study (males = 151 (60%), females = 102 (40%); mean age = 21.2, SD = 9.10). They completed the Dispositional Optimism Test-Revised (Scheier, Carver, &; Bridges, 1994 Scheier, M. F., Carver, C. S., &; Bridges, M. W. (1994). Distinguishing optimism from neuroticism and trait anxiety, self-mastery, and self-esteem: A re-evaluation of the Life Orientation Test. Journal of Personality and Social Psychology, 67(6), 1063–1078. https://doi.org/10.1037/0022-3514.67.6.1063[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]), the Altruistic Personality Scale (Rushton, Chrisjohn &; Fekken, 1981 Rushton, J. P., Chrisjohn, R. D., &; Fekken, G. C. (1981). The altruistic personality and the self-report altruism scale. Personality and Individual Differences, 1, 292–302. [Google Scholar]), and the Locus of Control Scale (Rotter, 1966 Rotter, J. B. (1966). Generalized expectancies for internal versus external control of reinforcement. Psychological Monographs, 80(1), 1–28. https://doi.org/10.1037/h0092976[Crossref], [PubMed] , [Google Scholar]). Multiple regression analysis indicated that internal locus of control positively predicted reciprocal altruism; while dispositional optimism did not. Future research should examine other dimensions of optimism such as adaptive utility, comparative and strategic dispositional optimism involved that may provide more insight into the understanding of reciprocal altruism in Nigeria.     

Using Item Response Theory to Develop a 60-Item Representation of the NEO PI–R Using the International Personality Item Pool: Development of the IPIP–NEO–60

Given advantages of freely available and modifiable measures, an increase in the use of measures developed from the International Personality Item Pool (IPIP), including the 300-item representation of the Revised NEO Personality Inventory (NEO PI–R; Costa &; McCrae, 1992a Costa, P., &; McCrae, R. (1992a). The five-factor model of personality and its relevance to personality disorders. Journal of Personality Disorders, 6, 343–359.[Crossref], [Web of Science ®] , [Google Scholar]) has occurred. The focus of this study was to use item response theory to develop a 60-item, IPIP-based measure of the Five-Factor Model (FFM) that provides equal representation of the FFM facets and to test the reliability and convergent and criterion validity of this measure compared to the NEO Five Factor Inventory (NEO-FFI). In an undergraduate sample (n = 359), scores from the NEO-FFI and IPIP–NEO–60 demonstrated good reliability and convergent validity with the NEO PI–R and IPIP–NEO–300. Additionally, across criterion variables in the undergraduate sample as well as a community-based sample (n = 757), the NEO-FFI and IPIP–NEO–60 demonstrated similar nomological networks across a wide range of external variables (r_ICC = .96). Finally, as expected, in an MTurk sample the IPIP–NEO–60 demonstrated advantages over the Big Five Inventory–2 (Soto &; John, 2017 Soto, C. J., &; John, O. P. (2017). The next Big Five Inventory (BFI–2): Developing and assessing a hierarchical model with 15 facets to enhance bandwidth, fidelity, and predictive power. Journal of Personality and Social Psychology, 113, 117–143.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]; n = 342) with regard to the Agreeableness domain content. The results suggest strong reliability and validity of the IPIP–NEO–60 scores.     

Side Streets and U-Turns: Effects of Context Switching,Direction Switching,and Factor Switching on Interitem Correlations and Misresponse Rates

This study tested implications of the context switching perspective proposed by Hamby, Ickes, and Babcock (2016 Hamby, T., Ickes, W., &; Babcock, M. (2016). Evidence for context switching in the effects of average item length and item-length variability on internal consistency. Journal of Personality Assessment, 98, 491–502. doi:10.1080/00223891.2016.1147044[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). Using trained raters to assess the amount of reframing required to interpret the meaning of the subsequent (second) item within all adjacent item pairs, we first established that this process variable could be measured reliably. Then, in the data for 18 personality measures drawn from 3 individual-difference domains, we found that the amount of reframing (i.e., context switching) needed to interpret successive items predicted both lower interitem correlations and a greater percentage of misresponders. Similarly, item pairs that were mismatched in “directional” wording also predicted both lower interitem correlations and more misresponders. Finally, item pairs representing different factors predicted lower interitem correlations. Although the effects of direction switching and factor switching were partially mediated by the amount of reframing required, they remained significant even when the mediating effect of reframing was statistically controlled. These results indicate that interpreting the meaning of test items is a task for which the level of difficulty can vary with each successive item, as a function of how the current item compares to the previous item in aspects such as its context generality or specificity, directional wording, and content domain.     

Developmental Contributions to Emotional Awareness

The Levels of Emotional Awareness Scale (LEAS) has received considerable support as a reliable and valid measure of individual differences in emotional awareness (EA) since the original report involving 40 participants (Lane, Quinlan, Schwartz, Walker, &; Zeitlin, 1990 Lane, R., Quinlan, D., Schwartz, G., Walker, P., &; Zeitlin, S. (1990). The Levels of Emotional Awareness Scale: A cognitive-developmental measure of emotion. Journal of Personality Assessment, 55, 124–134. doi:10.1080/00223891.1990.9674052[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). However, the hypothesized developmental nature of EA (conceptualized as a cognitive skill) has thus far only been examined in that 1 early study. Here we report multiple regression analyses on the entire sample of 94 participants who completed the LEAS as part of that original study, as well as the same developmental and affective measures used in the original report. We first observed that different developmental measures, including the Object Relations Inventory and the Sentence Completion Test of Ego Development, accounted for unique portions of the variance in LEAS scores. We also observed that higher LEAS scores were associated with greater within-category variance in the self-reported positive and guilt- and shame-related emotions people reported experiencing on a typical day. Based on these findings, we introduce a 3-dimensional cognitive-developmental framework that LEAS scores plausibly track, including (a) the transition from focusing on external/physical to internal/psychological characteristics, (b) greater conceptual complexity, and (c) self–other differentiation. We then discuss the implications of this framework for understanding the nature of EA and for future research.     

Associations Between Peer Pressure and Adolescents’ Binge Behaviors: The Role of Basic Needs and Coping

Framed from a framework based on the integration of self-determination theory (Ryan &; Deci, 2000 Ryan, R. M., &; Deci, E. L. (2000). Self-determination theory and the facilitation of intrinsic motivation, social development, and well-being. American Psychologist, 55(1), 68–78. doi:10.1037/0003-066X.55.1.68[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) and Endler and Parker’s (1990) conception of coping strategies, the authors analyzed the relationships between peer pressure and binge behaviors (binge eating and binge drinking) in adolescence. Moreover, the authors explored the mediating role of satisfaction/frustration of basic psychological needs and coping strategies in these associations. Participants were 570 high school students (M?=?15.75 years, SD?=?1.14 years) living in Italy. The study design was cross-sectional and adolescents were administered self-report questionnaires. Path analysis showed significant and positive direct associations of peer pressure with both binge eating and binge drinking. Moreover, findings show that there is an indirect path in which peer pressure is positively associated with need frustration that is related to the use of emotion-oriented coping strategies that, on their turn, are associated with binge eating. Differently, binge drinking seems to be only directly related to peer pressure. The authors put light to the complex nature of the relationships between peer pressure and binge behaviors in adolescence, taking into account the separate contribution of need satisfaction and need frustration, as well as of coping strategies. Finally, practical implications of the study are discussed.     

Perceived Esteem Support Predicts Competition Appraisals and Performance Satisfaction Among Varsity Athletes: A Test of Organizational Stressors as Moderators

Organizational stressors may be important factors influencing athletes' sport experiences. In this study, we examined organizational stressors as “background variables” (Gump & Matthews, 1999 Gump, B. B., & Matthews, K. A. (1999). Do background stressors influence reactivity to and recovery from acute stressors?. Journal of Applied Social Psychology, 29(3), 469–494. doi:10.1111/j.1559-1816.1999.tb01397.x[Crossref], [Web of Science ®] , [Google Scholar]) that may impact athletes' perceptions of support and appraisals of competitive stressors. Perceptions of available esteem support, organizational stressors, competitive appraisals, and performance satisfaction were prospectively examined among varsity team sport athletes (N = 84). Esteem support was positively related to athletes' perceptions of satisfaction with performance, and the indirect effect through secondary appraisal was significant. Two types of organizational stressors moderated the association between esteem support and secondary appraisal: More frequent coaching stressors weakened the association between esteem support and secondary appraisal, whereas more frequent team and culture stressors strengthened the association between esteem support and appraisal. These results support previous research (cf. Freeman & Rees, 2009 Freeman, P., & Rees, T. (2009). How does perceived support lead to better performance? An examination of potential mechanisms. Journal of Applied Sport Psychology, 21, 429–441. doi:10.1080/10413200903222913[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]), indicating that perceived available esteem support was positively associated with athletes' assessments that they had the necessary resources to cope with competitive stressors, which positively predicted performance satisfaction after a competition. Furthermore, these findings suggest that higher levels of coaching stressors were associated with poorer perceptions of having the necessary resources to cope with competition stressors, whereas conversely, higher team and culture stressors were not necessarily detrimental to athletes' perceptions of their resources to cope with competitive demands. These results suggest that different types of organizational stressors may have differential impacts on athletes' sport experiences.     

Theory and Analysis of Total,Direct, and Indirect Causal Effects

Mediation analysis, or more generally models with direct and indirect effects, are commonly used in the behavioral sciences. As we show in our illustrative example, traditional methods of mediation analysis that omit confounding variables can lead to systematically biased direct and indirect effects, even in the context of a randomized experiment. Therefore, several definitions of causal effects in mediation models have been presented in the literature (Baron &; Kenny, 1986 Baron, R.M., &; Kenny, D.A. (1986). The moderator-mediator variable distinction in social psychological research: Conceptual, strategic and statistical considerations. Journal of Personality and Social Psychology, 51, 1173–1182. doi:10.1037/0022-3514.51.6.1173[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]; Imai, Keele, &; Tingley, 2010 Imai, K., Keele, L., &; Tingley, D. (2010). A general approach to causal mediation analysis. Psychological Methods, 15, 309–334. doi:10.1037/a0020761[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]; Pearl, 2012 Pearl, J. (2012). The causal mediation formula: A guide to the assessment of pathways and mechanisms. Prevention Science, 13, 426–436. doi:10.1007/s11121-011-0270-1[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). We illustrate the stochastic theory of causal effects as an alternative foundation of causal mediation analysis based on probability theory. In this theory we define total, direct, and indirect effects and show how they can be identified in the context of our illustrative example. A particular strength of the stochastic theory of causal effects are the causality conditions that imply causal unbiasedness of effect estimates. The causality conditions have empirically testable implications and can be used for covariate selection. In the discussion, we highlight some similarities and differences of the stochastic theory of causal effects with other theories of causal effects.     

Model Conditioned Data Elasticity in Path Analysis: Assessing the “Confoundability” of Model/Data Characteristics

Much research has been directed at the validity of fit indices in Path Analysis and Structural Equation Modeling (e.g., Browne, MacCallum, Kim, Andersen, &; Glaser, 2002 Browne, M.W., MacCallum, R.C., Kim, C.T., Andersen, B.L., &; Glaser, R. (2002). When fit indices and residuals are incompatible.

Reply to Rodgers and Rowe (2002). Psychological Review, 109(3), 605–607.[Crossref] , [Google Scholar]) have encouraged researchers to investigate other criteria for comparing models, including model complexity. What has not been investigated is the inherent ability of a particular data set to be fitted with a constrained set of randomly generated linear models, which we call Model Conditioned Data Elasticity (DE). In this article we show how DE can be compared with the problem of equivalent models and a more general problem of the “confoundability” of data/model combinations (see MacCallum, Wegener, Uchino, &; Fabrigar, 1993 MacCallum, R.C., Wegener, D.T., Uchino, B.N., &; Fabrigar, L.R. (1993). The problem of equivalent models in applications of covariance structure analysis. Psychological Bulletin, 114(1), 185–199.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Using the DE package in R, we show how DE can be assessed through automated computer searches. Finally, we discuss how DE fits within the controversy surrounding the use of fit statistics.     

CS as an effect: action-based evaluative conditioning depends on temporal contiguity

ABSTRACT

In this study, we analysed Evaluative Conditioning (EC) with a recently introduced S-R paradigm [Blask et al., 2016 Blask, K. , Frings, C. , & Walther, E. (2016). Doing is for feeling. Journal of Experimental Psychology: General , 145 (10), 1263–1268. https://doi.org/ 10.1037/xge0000211 [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]. Doing is for feeling. Journal of Experimental Psychology: General, 145(10), 1263–1268], in which valence first transfers from an affective US to a response and then from this valence-laden response to a novel CS. Based on action control research, the CS in this procedure could be interpreted as an effect of the response. Hence, temporal contiguity of the valence-laden response and the CS should determine whether EC occurs. We tested this hypothesis in an experiment, in which we varied the time interval between the response and the subsequent CS. Results show that EC effects occurred only under conditions of high temporal contiguity thus supporting our assumptions. This finding sheds light on the processes underlying action-based EC in particular and evaluative learning in general.

Examining Current Conceptualizations of Psychopathology With the MMPI–2/MMPI–2–RF Restructured Clinical Scales: Preliminary Findings From a Cross-Cultural Study

Watson (2005 Watson, D. (2005). Rethinking the mood and anxiety disorders: A quantitative hierarchical model for DSM–V. Journal of Abnormal Psychology, 114, 522–536.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) proposed a hierarchical reorganization of the underlying structure of emotional disorders. This study cross-culturally evaluated Watson's (2005) structure of mood and anxiety disorders, using mainly dichotomous criteria, and explored the placement of obsessive–compulsive disorder (OCD) in this model. It also tested Sellbom, Ben-Porath, and Bagby's (2008) proposed elaboration of the 2-factor model (positive and negative activation) that incorporates a higher order dimension of demoralization. One hundred men and 133 women from psychiatric settings in Israel completed the Minnesota Multiphasic Personality Inventory–2 (Butcher et al., 2001 Butcher, J. N., Graham, J. R., Ben-Porath, Y. S., Tellegen, A., Dahlstrom, W. G., &; Kaemmer, B. (2001). Minnesota Multiphasic Personality Inventory–2 (MMPI–2): Manual for administration, scoring and interpretation (Rev. ed.). Minneapolis: University of Minnesota Press.[Crossref] , [Google Scholar]) and the Maudsley Obsessional–Compulsive Inventory (Hodgson &; Rachman, 1977 Hodgson, R. J., &; Rachman, S. (1977). Obsessive–compulsive complaints. Behaviour Research and Therapy, 15, 389–395.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). They were interviewed using the Mini International Neuropsychiatric Interview (Sheehan et al., 1998 Sheehan, D. V., Lecrubier, Y., Sheehan, K. H., Amorim, P., Janavs, J., &; Weiller, E. (1998). The Mini-International Neuropsychiatric Interview (M.I.N.I.): The development and validation of a structured diagnostic psychiatric interview for DSM–IV and ICD–10. Journal of Clinical Psychiatry, 59, 22–33.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Confirmatory factor analyses replicated Watson's structure for women but not for men. Mixed results were obtained regarding OCD's location in the model. Findings among women support the applicability of Watson's (2005) model across a variety of assessment modalities, as well as in a different language and for diversified cultural backgrounds. This conclusion, however, should be tempered in consideration of the results among men. Findings also provide evidence of the importance of demoralization in mood and anxiety disorders.     

The Structure of Multidimensional Perfectionism: Support for a Bifactor Model With a Dominant General Factor

Evidence suggests perfectionism is a multidimensional construct composed of 2 higher order factors: perfectionistic strivings and perfectionistic concerns. However, the substantial overlap between perfectionistic strivings and perfectionistic concerns is problematic, as are the unanswered questions regarding the structure of perfectionism following removal of common variance. This research addressed this through bifactor modeling. Three student samples (N = 742) completed Hewitt and Flett's (1991 Hewitt, P. L., &; Flett, G. L. (1991). Perfectionism in the self and social contexts: Conceptualization, assessment, and association with psychopathology. Journal of Personality and Social Psychology, 60, 456.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) Multidimensional Perfectionism Scale, Frost, Marten, Lahart, and Rosenblate's (1990 Frost, R. O., Marten, P., Lahart, C., &; Rosenblate, R. (1990). The dimensions of perfectionism. Cognitive Therapy and Research, 14, 449–468.[Crossref], [Web of Science ®] , [Google Scholar]) Multidimensional Perfectionism Scale, and Slaney, Rice, Mobley, Trippi, and Ashby's (2001 Slaney, R. B., Rice, K. G., Mobley, M., Trippi, J., &; Ashby, J. S. (2001). The revised almost perfect scale. Measurement and Evaluation in Counseling and Development, 34, 130–145.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) Almost Perfect Scale–Revised. Greater support was consistently found for the bifactor model, relative to the 2-factor model. Results suggest the bifactor model best represents the structure of perfectionism and provide preliminary support for the use of a general factor score. Researchers are cautioned that removal of general variance may render the reliability of specific factors (i.e., perfectionistic strivings and perfectionistic concerns) suspect.     

Of Fallacies and Errors,New and Repeated: A Rejoinder to Butcher et al. (2018)

Butcher, Hass, Greene, Nelson, Nichols, and Williams (2018 Butcher, J. N., Hass, G. A., Greene, R. L., Nelson, L. D., Nichols, D. S., & Williams, C. L. (2018).

Butcher et al. (2018 Butcher, J. N., Hass, G. A., Greene, R. L., Nelson, L. D., Nichols, D. S., & Williams, C. L. (2018).

In this rejoinder I refute (again) Butcher et al.’s assertion that empirical data raise questions about the “clinical sensitivity” of MMPI–2–RF scales, identify an extensive literature relevant to forensic use of the MMPI–2–RF that Butcher and colleagues have systematically ignored, and identify a series of logical and factual fallacies along with new and repeated errors of omission and commission in Butcher et al.’s response.     

A Polytomous Model of Cognitive Diagnostic Assessment for Graded Data

Pursuing the line of the difference models in IRT (Thissen &; Steinberg, 1986 Thissen, D., &; Steinberg, L. (1986). A taxonomy of item response models. Psychometrika, 51:567–577. doi:10.1007/BF02295596.[Crossref], [Web of Science ®] , [Google Scholar]), this article proposed a new cognitive diagnostic model for graded/polytomous data based on the deterministic input, noisy, and gate (Haertel, 1989 Haertel, E. H. (1989). Using restricted latent class models to map the skill structure of achievement items. Journal of Educational Measurement, 26, 333–352. doi:10.1111/j.1745-3984.1989.tb00336.x.[Crossref], [Web of Science ®] , [Google Scholar]; Junker &; Sijtsma, 2001 Junker, B. W., &; Sijtsma, K. (2001). Cognitive assessment models with few assumptions, and connections with nonparametric item response theory. Applied Psychological Measurement, 25, 258–272. doi:10.1177/01466210122032064.[Crossref], [Web of Science ®] , [Google Scholar]), which is named the DINA model for graded data (DINA-GD). We investigated the performance of a full Bayesian estimation of the proposed model. In the simulation, the classification accuracy and item recovery for the DINA-GD model were investigated. The results indicated that the proposed model had acceptable examinees' correct attribute classification rate and item parameter recovery. In addition, a real-data example was used to illustrate the application of this new model with the graded data or polytomously scored items.     

Bayes Factors Have Frequency Properties—This Should Not Be Ignored: A Rejoinder to Morey,Wagenmakers, and Rouder

Hoijtink, van Kooten, and Hulsker (2016 Hoijtink, H., van Kooten, P., &; Hulsker, K. (2016). Why Bayesian psychologists should change the way they used the Bayes factor. Multivariate Behavioral Research, 51, 1--9. doi: 10.1080/00273171.2014.969364.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) outline a research agenda for Bayesian psychologists: evaluate and use the frequency properties of Bayes factors. Morey, Wagenmakers, and Rouder (2016 Morey, R. D., Wagenmakers, E. -J., &; Rouder, J. N. (2016). Calibrated Bayes factors should not be used: A reply to Hoijtink, van Kooten, and Hulsker. Multivariate Behavioral Research, 51, 10--17. doi: 10.1080/00273171.2015.1052710.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) respond that Bayes factors calibrated using frequency properties should not be used. This paper contains the response of Hoijtink, van Kooten, and Hulsker to the criticism of Morey, Wagenmakers, and Rouder (2016 Morey, R. D., Wagenmakers, E. -J., &; Rouder, J. N. (2016).

Gender Differences in Academic Achievement: Is Writing an Exception to the Gender Similarities Hypothesis?

The gender similarities hypothesis by J. S. Hyde (2005 Hyde, J.S. (2005). The gender similarities hypothesis. American Psychologist, 60, 581–592.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]), based on large-scale reviews of studies, concludes that boys and girls are more alike than different on most psychological variables, including academic skills such as reading and math (J. S. Hyde, 2005 Hyde, J.S. (2005). The gender similarities hypothesis. American Psychologist, 60, 581–592.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Writing is an academic skill that may be an exception. The authors investigated gender differences in academic achievement using a large, nationally stratified sample of children and adolescents ranging from ages 7–19 years (N = 2,027). Achievement data were from the conormed sample for the Kaufman intelligence and achievement tests. Multiple-indicator, multiple-cause, and multigroup mean and covariance structure models were used to test for mean differences. Girls had higher latent reading ability and higher scores on a test of math computation, but the effect sizes were consistent with the gender similarities hypothesis. Conversely, girls scored higher on spelling and written expression, with effect sizes inconsistent with the gender similarities hypothesis. The findings remained the same after controlling for cognitive ability. Girls outperform boys on tasks of writing.
