Internal And External Validity

Abstract: Recently, Duriez, Fontaine and Hutsebaut (2000) and Fontaine, Duriez, Luyten and Hutsebaut (2003) constructed the Post-Critical Belief Scale in order to measure the two religiosity dimensions along which Wulff (1991 , 1997 ) summarized the various possible approaches to religion: Exclusion vs. Inclusion of Transcendence and Literal vs. Symbolic. In the present article, the German version of this scale is presented. Results obtained in a heterogeneous German sample (N = 216) suggest that the internal structure of the German version fits the internal structure of the original Dutch version. Moreover, the observed relation between the Literal vs. Symbolic dimension and racism, which was in line with previous studies ( Duriez, in press ), supports the external validity of the German version.

Discriminatory Capacity

Summary: Self-concept is a construct consisting of a group of specific self-perceptions that are hierarchically organized. Age-associated changes of self-concept are related to the individual's perception of the changes occurring throughout the aging process. The authors examined external validity and internal consistency of an instrument that has been developed to assess self-concept in older adults and examined self-concept's characteristics in two different contexts. Results confirm the multidimensionality of the scale and show a satisfactory external validity, indicating good discriminatory capacity. Findings support the hypothesis that older people who live in a nursing home have a poor self-esteem, self-concept, and psychological well-being and have a greater presence of depressive symptoms than people who live in their own home.

Preliminary Support

The Taylor Aggression Paradigm (TAP) is a frequently-used laboratory measure of aggressive behavior. However, the flexibility inherent in its implementation and analysis can undermine its validity. To test whether the TAP was a valid aggression measure irrespective of this flexibility, I conducted a preregistered study of a 25-trial version of the TAP using a single scoring approach with 160 diverse undergraduate participants. TAP scores showed agreement with other laboratory aggression measures and were magnified by an experimental provocation manipulation. Mixed evidence was found for associations with aggressive dispositions and real-world violence. These results provide preliminary support for this approach to the TAP to measure state-level aggressive behavior. However, more evidence is needed to assess the TAP’s external validity and ability to measure dispositional forms of aggression. Using preregistered designs, researchers should validate specific variants of their behavioral tasks in order to optimize the veridicality and reproducibility of psychological science.
