PurposeConsistent with the metaphor of narcissists as “emotional vampires” who leave their victims emotionally drained and devoid of energy, this research suggests that certain factors, such as subjective norms, perceived behavioral control, and religious beliefs, can reduce the level of narcissistic behavior in organizations. Drawing from the theory of planned behavior (TPB) and self-regulation theory, the current study evaluates the moderating role of Islamic religiosity in the relationship between subjective norms and the intention to behave narcissistically. In addition, this study examines the moderating role of afterlife belief in the relationship between perceived behavioral control and the intention to behave narcissistically.Design/methodology/approachThe research hypotheses were tested using two-wave survey data collected from managers of 103 service organizations (Study 1) and 323 employees of four service organizations (Study 2). This research applies structural equation modeling (SEM) to examine the proposed model using SmartPLS 3 software.FindingsIslamic religiosity had a negative moderating role in the relationship between subjective norms and the intention to behave narcissistically (Study 1 and Study 2). In addition, subjective norms and perceived behavioral control had significant positive effects on the intention to engage in narcissistic behavior among managers (Study 1). However, perceived behavioral control had no significant effect on the intention to engage in narcissistic behavior among employees (Study 2).Originality/valueThe current study not only tests the applicability of the TPB to narcissistic behaviors in Islamic organizations, but it also extends the classic TPB framework by including two moderating variables – Islamic religiosity and afterlife belief.
