Individuals differ in the type and severity of the difficulties they face when making a career decision. Relying on the Gati, Krausz, and Osipow (1996) taxonomy of career decision-making difficulties, we elicited the judgements of 28 career counselling experts about factors that contribute to the perceived severity of the difficulties. Difficulties attributed to an internal or emotional cause were judged as more severe than difficulties attributed to an external or cognitive cause. With respect to the consequences, difficulties that prevent making a decision, or those that require long-term treatment, were judged as more severe than difficulties that may lead to a non-optimal decision, and those that require a short-term treatment. The analysis revealed that the factor that most affected the experts' severity judgements was the expected length of treatment. Treatment priority was affected only partially by severity, reflecting the role of other considerations.
