Structured Latent Curve Models for the Study of Change in Multivariate Repeated Measures.

This article considers a structured latent curve model for multiple repeated measures. In a structured latent curve model, a smooth nonlinear function characterizes the mean response. A first-order Taylor polynomial taken with regard to the mean function defines elements of a restricted factor matrix that may include parameters that enter nonlinearly. Similar to factor scores, random coefficients are combined with the factor matrix to produce individual latent curves that need not follow the same form as the mean curve. Here the associations between change characteristics in multiple repeated measures are studied. A factor analysis model for covariates is included as a means of relating latent covariates to the factors characterizing change in different repeated measures. An example is provided.

Validation of Idiosyncratic Cognitive Schema in Cognitive Case Formulations: An Intraindividual Idiographic Approach.

This article describes a method for the intraindividual clinical validation of a cognitive case formulation (CCF) involving hypotheses about the patient's idiosyncratic cognitive schema (ICS). The two-stage approach begins by testing the convergent and discriminant validity of the hypothesized ICS against the individual's daily ratings of cognition items using confirmatory dynamic factor analysis. The second stage evaluates the extent to which the ICS factor scores predict daily variability in symptoms and distress and further addresses convergent and discriminant validity by evaluating intraindividual cognitive content specificity and the incremental validity of the idiographic cognition factors compared with nomothetic measures of thoughts/beliefs. This approach to validating idiographic assessment is illustrated with the CCF of a woman with comorbid mood and anxiety disorders. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Escapable Conclusions: Toomela (2003) and the Universality of Trait Structure.

A. Toomela (2003) concluded that personality structure may be shaped by a cultural mechanism, word meaning structure, and that the apparent universality of the Five-Factor Model (FFM) was the result of inadequate sampling of concrete thinkers. A reanalysis using targeted rotation showed that the intended structure was generally replicated; small deviations in the most concrete thinkers were probably due to measurement error. The reanalysis authors found no evidence of structural differences in a second sample of adults classified as concrete or abstract thinkers. The FFM structure has been replicated in many samples containing individuals with cognitive or educational limitations; observer ratings may be preferred if these limitations are severe. To date, there is no compelling evidence that culture affects personality structure. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
