With the purpose of increasing the knowledge of the psychometric properties of the 70‐item Danish Word Association Test, data from three samples of non‐patients and psychiatric patients ( N = 326) were used to provide two measures of affectivity of the stimulus words, response heterogeneity and reaction time prolongation. It was possible to fit an item response theory one‐parameter measurement (Rasch) model to the number of reaction time prolongations (≥3 seconds) for 54 of the stimulus words. Correlation between Rasch‐model item parameters and response heterogeneity was high ( r = 0.86), while no correlation was found between either of these measures and frequency of the stimulus words in the Danish language. Both measures of stimulus affectivity supported a theoretically based classification of stimulus words as emotional or neutral. Response heterogeneity measures and Rasch measurement item and person parameters for reaction time prolongations are provided.
