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; Imai, Keele, &; Tingley, 2010; Pearl, 2012). 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. 相似文献

Watson (2005) 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) and the Maudsley Obsessional–Compulsive Inventory (Hodgson &; Rachman, 1977). They were interviewed using the Mini International Neuropsychiatric Interview (Sheehan et al., 1998). 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. 相似文献

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) Multidimensional Perfectionism Scale, Frost, Marten, Lahart, and Rosenblate's (1990) Multidimensional Perfectionism Scale, and Slaney, Rice, Mobley, Trippi, and Ashby's (2001) 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. 相似文献

In this study we developed a short version of the Individuation Test for Emerging Adults (ITEA–S) and tested its measurement invariance across Slovene and U.S. samples of emerging adults. The item reduction process resulted in retaining 21 out of 36 items. The content analysis of the retained and discarded items revealed that the ITEA–S adequately measures the 5 individuation domains (support seeking, connectedness, intrusiveness, self-reliance, and fear of disappointing the parent). In our samples, the ITEA–S demonstrated evidence for construct validity and its 5 scales showed adequate internal consistency. The scale scores were also meaningfully associated with the relevant demographic variables in both countries, as well as the three scales of the Psychological Separation Inventory (Hoffman, 1984; the Slovene sample), and the scales of the Differentiation of Self–Revised questionnaire (Skowron &; Schmitt, 2003; the U.S. sample). The results of multiple group confirmatory factor analyses supported the hypothesis of full metric and partial scalar invariance for both ITEA–S forms (in relation to mother and father) across the 2 country groups. 相似文献

Pursuing the line of the difference models in IRT (Thissen &; Steinberg, 1986), this article proposed a new cognitive diagnostic model for graded/polytomous data based on the deterministic input, noisy, and gate (Haertel, 1989; Junker &; Sijtsma, 2001), 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. 相似文献

Hoijtink, Kooten, and Hulsker (2016) present a method for choosing the prior distribution for an analysis with Bayes factor that is based on controlling error rates, which they advocate as an alternative to our more subjective methods (Morey &; Rouder, 2014; Rouder, Speckman, Sun, Morey, &; Iverson, 2009; Wagenmakers, Wetzels, Borsboom, &; van der Maas, 2011). We show that the method they advocate amounts to a simple significance test, and that the resulting Bayes factors are not interpretable. Additionally, their method fails in common circumstances, and has the potential to yield arbitrarily high Type II error rates. After critiquing their method, we outline the position on subjectivity that underlies our advocacy of Bayes factors. 相似文献

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; Heene, Hilbert, Draxler, Ziegler, &; Bühner, 2011; Hu &; Bentler, 1999; Marsh, Hau, &; Wen, 2004). Recent developments (e.g., Preacher, 2006; Roberts &; Pashler, 2000, 2002) 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). 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. 相似文献

Pictures are widely used as stimuli in implicit motive tests. Hybrid forms of such tests present pictures and declarative statements underneath pictures. Some authors have argued that explicitly declaring agreement with motive-related statements presented underneath pictures might shift the validity of such tests from capturing less implicit motives to more explicit motives. If that is the case, pictures as elicitors of implicit motives might become less relevant. Adopting the views on validity presented by Borsboom, Mellenbergh, and van Heerden (2004) and Bornstein (2011), as well as item generation theory, we investigated whether the availability of pictures in hybrid motive tests causally affects test scores. To this end, we administered the Multi-Motive Grid (MMG; Sokolowski, Schmalt, Langens, &; Puca, 2000), as an example of a hybrid motive test, either with or without pictures to 108 participants. Results revealed that the availability of pictures had no effect on 3 out of 6 test scores. Furthermore, eliminating pictures had only inconsistent effects on correlations with a test of explicit motives. We conclude that pictures might not unanimously elicit motives in implicit motive tests that use declarative statements as response options. 相似文献

Often when participants have missing scores on one or more of the items comprising a scale, researchers compute prorated scale scores by averaging the available items. Methodologists have cautioned that proration may make strict assumptions about the mean and covariance structures of the items comprising the scale (Schafer &; Graham, 2002; Graham, 2009; Enders, 2010). We investigated proration empirically and found that it resulted in bias even under a missing completely at random (MCAR) mechanism. To encourage researchers to forgo proration, we describe a full information maximum likelihood (FIML) approach to item-level missing data handling that mitigates the loss in power due to missing scale scores and utilizes the available item-level data without altering the substantive analysis. Specifically, we propose treating the scale score as missing whenever one or more of the items are missing and incorporating items as auxiliary variables. Our simulations suggest that item-level missing data handling drastically increases power relative to scale-level missing data handling. These results have important practical implications, especially when recruiting more participants is prohibitively difficult or expensive. Finally, we illustrate the proposed method with data from an online chronic pain management program. 相似文献

The aim of this study was to examine the factor structure and the psychometric properties of the Psychotherapy Relationship Questionnaire (PRQ; Bradley, Heim, &; Westen, 2005), a clinician report instrument that measures a wide spectrum of thoughts, feelings, motives, conflicts, and behaviors expressed by patients toward their therapists in psychotherapy. A national sample of psychiatrists and clinical psychologists (N = 314) of different theoretical orientations completed the PRQ, as well as the Shedler–Westen Assessment Procedure–200 (SWAP–200; Westen &; Shedler, 1999a, 1999b) to assess the personality of a patient in their care. Factor-analytic procedures identified 6 transference dimensions that showed excellent internal consistencies: (a) hostile, (b) positive/working alliance, (c) special/entitled, (d) anxious/preoccupied, (e) avoidant/dismissing attachment, and (f) sexualized. Factor scores were significantly related to patients’ personality characteristics and psychological functioning, regardless of the clinicians’ orientations. The findings support that the PRQ is a valid and reliable tool for evaluating the patients’ relational patterns emerging in clinical practice in a clinically coherent and psychometrically robust way. Clinicians’ careful understanding of these patterns can be very useful for making accurate diagnostic formulations, as well as for providing a roadmap for effective therapeutic intervention. 相似文献

The gender similarities hypothesis by J. S. Hyde (2005), 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). 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. 相似文献

Research on motivational climates within athletics has focused on mastery and ego achievement approaches, yielding different psychological consequences (Smith, Smoll, &; Cumming, 2007). Further, the motivational climate may interact with athletes' trait characteristics, such as grit, resulting in different outcomes. Grit may alter athletes' experience of the motivational climate by helping them remain oriented to their long-term quest in sport (Duckworth, Peterson, Matthews, &; Kelly, 2007). However, to date, the impact of these motivational climates and potential moderating factors on athlete performance remains in question, as the research utilizing objective measures of athletic performance is limited (Harwood, Keegan, Smith, &; Raine, 2015). We used a motivational research paradigm (e.g., Mueller &; Dweck, 1998) to examine the effects of mastery- or ego-involving feedback on 71 high school adolescent soccer players' (Mage = 15.81) performance on a kicking task. Then we explored the potential moderating effects of grit on the relationship between motivational feedback and the athletes' performance, desire to persist, and choice of task difficulty on a soccer task. Athletes performed significantly better receiving mastery- as opposed to ego-involving feedback. Further, grit was a significant moderator of the feedback-shooting performance relationship, accounting for 3.9% of variance. Simple slopes analysis revealed a significant effect for low (B = 13.32, SEb = 4.44, p =.004, t = 2.99), but not high (B = 2.11, SEb = 4.31, p =.63, t = 0.49), grit on task performance. These results suggest that the feedback athletes receive matters, especially for those low in grit. 相似文献

Heath, Weiler, Marriott, Elliott, and Binstead (2011) and Heath, Samani, Tremblay, and Elliott (2016) have claimed that there are dissociable movement times for amplitude and width manipulations in the Fitts' paradigm. This may to some extent be true, but the Heath et al. (2011) and Heath et al. (2016) data do not support that contention, as shown in this comment. It is shown that data from the research of Heath et al. is not in the range of index of difficulty where ongoing visual control would be used and hence their fits of data to Fitts' law are spurious. The data of Heath et al. (2011) for arm movements and for the primary eye saccade submovements of Heath et al. (2016) are well correlated by the ballistic movement time equation of Hoffmann (1981) and Gan and Hoffmann (1988). When the ballistic equation is used to model data for constant amplitude and constant target width conditions, the effects of the amplitude and width manipulations disappear. Other research indicates that the independent effects of movement amplitude occur due to changes in the time for the distance-covering phase of the movement. 相似文献

A Rorschach study of boundary disturbance and thought disorder by Blatt and Ritzler (1974) was replicated using the newly developed Picture Projection Test (PPT), a modern alternative to the Thematic Apperception Test (TAT). Twenty-five individuals with pathological Rorschach records were compared to 25 individuals with nonpathological Rorschachs. A coding system for the PPT was devised using concepts from the Blatt and Ritzler study and Rorschach thought disorder variables from the Comprehensive System (Exner, 2003). The pathological group showed significantly more boundary disturbance on the PPT. Only one Contamination (the most severe manifestation of boundary disturbance and thought disorder) appeared in the pathological group. The nonpathological group had no Contamination responses. It is recommended that future researchers repeat the study with a psychotic group compared to a nonpsychotic group. 相似文献

The purpose of this study is to explore whether 2 different dimensions of personality, when assessed at an implicit level with the Thematic Apperception Test (TAT; Murray, 1943) will show a theoretically meaningful coherence not demonstrated when 1 is assessed at an implicit level and the other at an explicit level. Gender identity and defense mechanisms were assessed implicitly using the TAT. Gender identity was compared with a self-report measure of gender-related attributes assessed at the explicit level. The results showed a theoretically meaningful coherence when different dispositions were assessed at the same level, but a lack of agreement when similar dispositions were assessed at different levels. The study is based on a secondary analysis of data from 2 previously published papers (Cramer, 1998; Cramer &; Westergren, 1999). 相似文献

When solving a simple probabilistic problem, people tend to build an incomplete mental representation. We observe this pattern in responses to probabilistic problems over a set of premises using the conjunction, disjunction, and conditional propositional connectives. The mental model theory of extensional reasoning explains this bias towards underestimating the number of possibilities: In reckoning with different interpretations of the premises (logical rules, mental model theoretical, and, specific to conditional premises, conjunction and biconditional interpretation) the mental model theory accounts for the majority of observations. Different interpretations of a premise result in a build-up of mental models that are often incomplete. These mental models are processed using either an extensional strategy relying on proportions amongst models, or a conflict monitoring strategy. The consequence of considering too few possibilities is an erroneous probability estimate akin to that faced by decision makers who fail to generate and consider all alternatives, a characteristic of bounded rationality. We compare our results to the results published by Johnson-Laird, Legrenzi, Girotto, Legrenzi, and Caverni [Johnson-Laird, P., Legrenzi, P., Girotto, V., Legrenzi, M., &; Caverni, J. (1999). Naive probability: A mental model theory of extensional reasoning. Psychological Review, 106, 62–88. doi:10.1037/0033-295X.106.1.62], and we observe lower performance levels than those in the original article. 相似文献

AbstractResearch evidence suggests Therapeutic Assessment positively affects clients with problems in living, including clients with personality disorders, who are typically quite resistant to change. Importantly, this change takes place quickly, in relatively few sessions. This article draws on a relatively new evolutionary-based theory of epistemic trust (ET) and epistemic hypervigilance (EH) as a lens to plausibly explain the efficacy of TA, and especially its influence on PD clients' alliance and motivation for subsequent psychotherapy (Fonagy, Luyten, &; Alison, 2015). ET is the willingness to take in relevant interpersonally transmited information and it is essential to the immediate success of psychotherapy and its long-term impact. The collaborative, intersubjective framework of TA and many of its specific techniques might be understood as highly relevant to restoring ET in clients, especially those with PD. We close by discussing implications for psychological assessment, psychotherapy, and research. 相似文献

Recently, psychologists have emphasized the response process—that is, the psychological operations and behaviors that lead to test scores—when designing psychological tests, interpreting their results, and refining their validity. To illustrate the centrality of the response process in construct validity and test interpretation, we provide a historical, conceptual, and empirical review of the main uses of the background white space of the Rorschach cards, called space reversal (SR) and space integration (SI) in the Rorschach Performance Assessment System. We show how SR and SI's unique response processes result in different interpretations, and that reviewing their literatures with these distinct interpretations in mind produces the expected patterns of convergent and discriminant validity. That is, SR was uniquely related to measures of oppositionality; SI was uniquely related to measures of cognitive complexity; and both SR and SI were related to measures of creativity. Our review further suggests that the Comprehensive System use of a single space code for all uses of white space likely led to its lack of meta-analytic support as a measure of oppositionality (Mihura, Meyer, Dumitrascu, &; Bombel, 2013). We close by discussing the use of the response process to improve test interpretation, develop better measures, and advance the design of research. 相似文献

The advent of a dimensional model of personality disorder included in DSM–5 has necessitated the development of a new measurement scheme, specifically a self-report questionnaire termed the Personality Inventory for DSM–5 (PID–5; Krueger, Derringer, Markon, Watson, &; Skodol, 2012). However, there are many threats to the validity of a self-report measure, including response inconsistency. This study outlines the development of an inconsistency scale for the PID–5. Across both college student and clinical samples, the inconsistency scale was able to reliably differentiate real from random responding. Random responses led to increased scores on the PID–5 facets, indicating the importance of detecting inconsistent responding prior to test interpretation. Thus, this inconsistency scale could be of use to researchers and clinicians in detecting inconsistent responses to this new personality disorder measure. 相似文献

The present study investigated interactions between working memory load and perceptual load. The load theory (Lavie, Hirst, de Fockert, &; Viding, 2004) claims that perceptual load decreases distractor interference, whereas working memory load increases interference. However, recent studies showed that effects of working memory might depend on the relationship between modalities of working memory and task stimuli. Here, we examined whether the relationship between working memory load and perceptual load would remain the same across modalities. The results of Experiment 1 showed that verbal working memory load did not affect a compatibility effect for low perceptual load, whereas it increased the compatibility effect for high perceptual load. In Experiment 2, the compatibility effect remained the same regardless of visual working memory load. These results suggest that the effects of working memory load and perceptual load depend on the relationship between the modalities of working memory and stimuli. 相似文献
