Validity of QOL Impact Attributions to Specific Diseases: A Multitrait-Multimethod Comparison

The multitrait-multimethod approach to construct validity.

The multitrait-multimethod matrix approach as proposed by Campbell and Fiske (1959) was an important contribution to our understanding of the nature of validation procedures. There are, however, problems encountered when using the Campbell and Fiske (1959) approach. The purpose of this article is to discuss the method and selected problems, and to propose an alternate approach to address those ...

Validity oF multiple achieVement goals : a multitrait - multimethod approach

The construct validity of acceptance: a multitrait-multimethod investigation.

Despite increasing clinical and empirical attention, the construct validity of acceptance has not been extensively investigated. The present study utilized a multitrait-multimethod design and a correlated trait-correlated method minus one [CT-C(M-1)] confirmatory factor analytic model to assess acceptance's convergent validity across methods and discriminant validity in comparison to cognitive ...

A Multilevel Multitrait-Multimethod Analysis

The classical multitrait-multimethod (MTMM) matrix can be viewed as a two-dimensional cross-classification of traits and methods. Beside commonly used analysis methods such as structural equation modeling and generalizability theory, multilevel analysis offers attractive possibilities. If the focus is only on analyzing classical MTMM data, the multilevel approach has no surplus value, because t...

Multitrait-Multimethod Data

A taxonomy of covariance structure models for representing multitrait-multimethod data is presented. Using this taxonomy, it is possible to formulate alternate series of hierarchically ordered, or nested, models for such data. By specifying hierarchically nested models, significance tests of differences between competing models are available. Within the proposed framework, specific model compar...
