Assessment of exposure to political violence and other potentially traumatizing events. A critical review

Authors


Abstract

This paper focuses on the common use of internal-consistency reliability, testretest, and interrater correlations based on counts of events, events sampling, and factor-analytic techniques in assessment of exposure to political violence and other potentially traumatizing events. The author attributes the continued use of these strategies to a tendency among researchers to identify items from conventional events lists as effect indicators. Through a discussion of four alternative measurement models, the rationale is provided for the proposition that exposure to political violence and similar constructs should be treated as composite variables with causal indicators, rather than as latent variables with effect indicators.
