The value of pre-exposure prophylaxis: A case series of US Marines infected with leptospirosis

Dimensional models have gained traction for conceptualizing personality pathology, with increasing evidence that dimensions in those models link with general models of personality. One link that has been debated is between conscientiousness and the pathological traits of Obsessive-Compulsive Personality Disorder (OCPD), such as compulsivity, perfectionism, and workaholism. Research has supported the conceptualization of those pathological traits as maladaptively high conscientiousness. However, a pressing question is whether measures intended to assess maladaptive conscientiousness remain high-fidelity measures of conscientiousness, or if they become saturated with neuroticism. The only instrument that is ideally situated to answer this conceptual question is the Five Factor Obsessive Compulsive Inventory (FFOCI), because it was specifically developed as a measure of conscientiousness that assesses the maladaptive ranges of the trait. Thus, we investigated how well the FFOCI's conscientiousness score replicated the nomological networks of traditional measures of conscien-tiousness. A sample of 305 participants, sampled for enhanced representation of the extreme ends of the conscientiousness distribution, completed a set of self-report questionnaires. In addition, 150 nominated peer informants described the targets' personality. Results provided cross-method support for the FFOCI's domain score as a measure of conscientiousness, including strong discrimination from neuroticism scores. This suggests that maladaptive conscientiousness is still conscientiousness and that the FFOCI assesses the trait in a way that uniquely spans traditional boundaries of normal and pathological measures.
