1. The Measurement of Subjective Well-Being: Item Response Theory, Classical Test Theory, and Multidimensional Item Response Theory
Abstract : For over 35 years, modern science has conceptualized happiness as subjective well-being, which has until recently been understood as a dual construct consisting of an affective component (positive and negative affect) and a cognitive component (life satisfaction). Nevertheless, for the last five years, theoretical work and both quantitative and qualitative empirical work have suggested that the concept of subjective well-being omits both a lay and an Eastern way of understanding happiness.

3. A Facet Model of the Logical Operational Structures of Piaget's Theory : Guttman's Facet Design applied to Piaget's Theory
Abstract : This thesis explored whether the complex structure of Piaget's theory of operational thinking could be synthesized into a facet model by means of facet design. The aims were: (1) to deduce from detailed conceptual analyses of 12 of Piaget's classical experiments the essential parts of the operational structures (Study I); (2) to explore the internal structure of his constructs in terms of a mapping sentence (Study II); (3) to study the hierarchical structure of the interrelationships between the constructs (Study III); and (4) to apply the facet model in the development of test items (Study II and IV).
