  • Construct Validation using multitrait multimethod twin data the case of a general factor of personality
    European Journal of Personality, 2010
    Co-Authors: Rainer Riemann, Christian Kandler
    Abstract:

    We describe a behavioural genetic extension of the classic: multitrait-multimethod study design that allows estimating genetic and environmental influences on method effects in twin studies (MTMM-T) Genetic effects and effects of the environment shared by siblings are interpreted as indicators of convergent validity. In an application of the MTMM study design, we used self- and peer report data to examine the higher-order structure of the NEO-PI-R Structural equation modelling did not support a general factor of personality in multimethod data. The higher-order factor Stability turns out to be, at most, a weak trait factor Genetic effects on method factors indicate that especially self-reports hut also peer reports show convergent validity between twins but not between methods Copyright (C) 2010 John Wiley & Sons, Ltd.

  • developing a strong program of Construct Validation a test anxiety example
    Educational Measurement: Issues and Practice, 2005
    Co-Authors: Jeri Benson
    Abstract:

    What would a strong program of Construct Validation look like for the concept of test anxiety? What are the components of strong Validation programs? In particular, how does structural equation modeling fit into such a program?

  • measuring test anxiety in children scale development and internal Construct Validation
    Anxiety Stress and Coping, 2004
    Co-Authors: Douglas G Wren, Jeri Benson
    Abstract:

    Given the increased testing of school-aged children in the United States there is a need for a current and valid scale to measure the effects of test anxiety in children. The domain of children's test anxiety was theorized to be comprised of three dimensions: thoughts, autonomic reactions, and off-task behaviors. Four stages are described in the evolution of the Children's Test Anxiety Scale (CTAS): planning, Construction, quantitative evaluation, and Validation. A 50-item scale was administered to a development sample (N=230) of children in grades 3–6 to obtain item analysis and reliability estimates which resulted in a refined 30-item scale. The reduced scale was administered to a Validation sample (N=261) to obtain Construct validity evidence. A three-factor structure fit the data reasonably well. Recommendations for future research with the scale are described.

  • Construct Validation theory applied to the study of personality dysfunction
    Journal of Personality, 2012
    Co-Authors: Tamika C B Zapolski, Leila Guller, Gregory T Smith
    Abstract:

    The authors review theory Validation and Construct Validation principles as related to the study of personality dysfunction. Historically, personality disorders have been understood to be syndromes of heterogeneous symptoms. The authors argue that the syndrome approach to description results in diagnoses of unclear meaning and constrained validity. The alternative approach of describing personality dysfunction in terms of homogeneous dimensions of functioning avoids the problems of the syndromal approach and has been shown to provide more valid description and diagnosis. The authors further argue that description based on homogeneous dimensions of personality function/dysfunction is more useful because it provides direct connections to validated treatments.

  • on the value of homogeneous Constructs for Construct Validation theory testing and the description of psychopathology
    Psychological Assessment, 2009
    Co-Authors: Gregory T Smith, Denis M Mccarthy, Tamika C B Zapolski
    Abstract:

    The authors argue for a significant shift in how clinical psychology researchers conduct Construct Validation and theory Validation tests. They argue that sound theory and Validation tests can best be conducted on measures of unidimensional or homogeneous Constructs. Hierarchical organizations of such Constructs are useful descriptively and theoretically, but higher order composites do not refer to definable psychological processes. Application of this perspective to the approach of the Diagnostic and Statistical Manual of Mental Disorders to describing psychopathology calls into doubt the traditional use of the syndromal approach, in which single scores reflect the presence of multidimensional disorders. For many forms of psychological dysfunction, this approach does not appear optimal and may need to be discarded. The authors note that their perspective represents a straightforward application of existing psychometric theory, they demonstrate the practical value of adopting this perspective, and they provide evidence that this shift is already under way among clinical researchers. Description in terms of homogeneous dimensions provides improved validity, utility, and parsimony. In contrast, the use of composite diagnoses can retard scientific progress and hamper clinicians' efforts to understand and treat dysfunction.
