Dark side personality styles as predictors of task, contextual, and job performance

Many meta-analyses and hundreds of primary studies have been carried out on the criterion-oriented validity of personality measures for predicting job performance. The Five-Factor Model of personality has been used as a frame for analyzing the empirical evidence. However, the research in industrial, work and organizational psychology has not examined the relationship between the dysfunctional tendencies of personality and the personality disorders as described in DSM-IV (Axis II) Diagnostic and Statistical Manual of Mental Disorders and job performance. The present paper examines the relationship between job performance and the dysfunctional personality styles included in a non-clinical personality inventory developed to assess personality tendencies related to the dysfunctional (normal) personality styles and the personality disorders in work settings. This inventory assesses 14 dysfunctional personality styles and was given to a sample of 85 applicants. The job performance was rated by the direct supervisor 8 months later, and three measures were obtained: task performance, contextual performance, and overall job performance. The results showed that the seven dysfunctional personality styles (suspicious, shy, sad, pessimistic, sufferer, eccentric, and risky) predicted the three measures of job performance. The egocentric personality style negatively predicted contextual performance. Finally, the submitted style predicted task performance. With the exception of the risky personality style, the rest of the styles mainly consisted of Neuroticism. Implications for the research and practice of personnel selection are discussed.
