Structural equation modeling of mediation and moderation with contextual factors
(Lawrence Erlbaum Associates, 2007) -
Implicit attitude measures: Consistency, stability, and convergent validity
(2001)In recent years, several techniques have been developed to measure implicit social cognition. Despite their increased use, little attention has been devoted to their reliability and validity. This article undertakes a ... -
Sample size in factor analysis: The role of model error
(2001)This article examines effects of sample size and other design features on correspondence between factors obtained from analysis of sample data and those present in the population from which the samples were drawn. We extend ... -
Comments on the Meehl-Waller procedure for appraisal of path analysis models
(2002)P. E. Meehl and N. G. Waller (2002) proposed an innovative method for assessing path analysis models wherein they subjected a given model, along with a set of alternatives, to risky tests using selected elements of a sample ... -
On the practice of dichotomization of quantitative variables
(2002)The authors examine the practice of dichotomization of quantitative measures, wherein relationships among variables are examined after 1 or more variables have been converted to dichotomous variables by splitting the sample ... -
Exploratory factor analysis in behavior genetics research: Factor recovery with small sample sizes
(2002)Results of a Monte Carlo study of exploratory factor analysis demonstrate that in studies characterized by low sample sizes the population factor structure can be adequately recovered if communalities are high, model error ... -
Chronic stress and age-related increases in the proinflammatory cytokine interleukin-6
(2003)Overproduction of IL-6, a proinflammatory cytokine, is associated with a spectrum of age-related conditions including cardiovascular disease, osteoporosis, arthritis, type 2 diabetes, certain cancers, periodontal disease, ... -
Repairing Tom Swift's electric factor analysis machine
(2003)Proper use of exploratory factor analysis (EFA) requires the researcher to make a series of careful decisions. Despite attempts by Floyd and Widaman (1995), Fabrigar, Wegener, MacCallum, and Strahan (1999), and others to ... -
SPSS and SAS procedures for estimating indirect effects in simple mediation models
(2004)Researchers often conduct mediation analysis in order to indirectly assess the effect of a proposed cause on some outcome through a proposed mediator. The utility of mediation analysis stems from its ability to go beyond ... -
Use of the extreme groups approach: A critical reexamination and new recommendations
(2005)Analysis of continuous variables sometimes proceeds by selecting individuals on the basis of extreme scores of a sample distribution and submitting only those extreme scores to further analysis. This sampling method is ... -
Coping with stereotype threat: Denial as an impression management strategy
(2005)Four experiments tested the hypothesis that people who are concerned with impression management cope with stereotype threat through denial. Consistent with this hypothesis, temporary employees threatened by a stereotype ... -
Conceptualizing and testing random indirect effects and moderated mediation in multilevel models: New procedures and recommendations
(2006)The authors propose new procedures for evaluating direct, indirect, and total effects in multilevel models when all relevant variables are measured at Level 1 and all effects are random. Formulas are provided for the mean ... -
The effects of early socializaiton experiences on content mastery and outcomes: A mediational approach
(2006)This field study examined how early socialization experiences affect new employee mastery of socialization content and socialization outcomes. New employees reported the realism of their preentry knowledge and the helpfulness ... -
Testing complex correlational hypotheses using structural equation modeling
(2006)It is often of interest to estimate partial or semipartial correlation coefficients as indexes of the linear association between 2 variables after partialing one or both for the influence of covariates. Squaring these ... -
Parental verbal abuse and the mediating role of self-criticism in adult internalizing disorders
(2006)Background: Researchers (e.g., [Gibb, B.E., 2002. Childhood maltreatment and negative cognitive styles. A quantitative and qualitative review. Clinical Psychology Review, 22 (2), 223–246]; [Rose, D.T., Abramson, L.Y., ... -
Quantifying parsimony in structural equation modeling
(2006)Fitting propensity (FP) is defined as a model's average ability to fit diverse data patterns, all else being equal. The relevance of FP to model selection is examined in the context of structural equation modeling (SEM). ... -
Computational tools for probing interaction effects in multiple linear regression, multilevel modeling, and latent curve analysis
(2007-04-09)Simple slopes, regions of significance, and confidence bands are commonly used to evaluate interactions in multiple linear regression (MLR) models, and the use of these techniques has recently been extended to multilevel ... -
A lower boundary for category formation in preverbal infants
(Cambridge University Press, 1987-06) -
Depression during exacerbations in multiple sclerosis: the importance of uncertainty
(ARNOLD, HODDER HEADLINE PLC, 2001-08)The following correlates of depression were examined in a sample of 166 patients with clinically definite relapsing-remitting (n=140) or secondary progressive (n=26) multiple sclerosis: (a) the present state of the patients' ...
