This study analyzed the relationship between each of five decision-making styles, including Rational, Intuitive, Dependent, Avoidant, and Spontaneous (Scott & Bruce, 1995) and two indicators of stress, Perceived stress and Sleep quality, among administrative officers and investigators at three Swedish public authorities: The National Tax board, the Social Insurance agency, and the Police authority (n = 472). Results showed that Avoidant style and, to some extent, the Dependent style were significantly associated with higher Perceived Stress and poorer Sleep. The results for the specific organizations showed that the Rational style was advantageous at the Tax board only.
