The other side of the coin: the mediating role of maladaptive perfectionism in the impact of imposter phenomenon on individual and organizational outcomes among healthcare professionals

Abstract The imposter phenomenon (IP) has been widely studied for its negative psychological effects, yet its organizational implications, particularly in healthcare, remain underexplored. Existing research has mostly focused on individual outcomes such as anxiety, burnout, and stress, while neglecting integrative models that explain how IP leads to broader personal and organizational consequences. In particular, the mediating role of maladaptive perfectionism (MP) in linking IP to reduced life satisfaction, increased workaholism, and higher turnover intention has not been systematically examined in healthcare contexts. This study addresses this gap by developing and testing an integrative structural model that positions MP as a key psychological mechanism through which IP affects both individual and organizational outcomes. Data were collected via a survey of 993 healthcare professionals in Istanbul, Türkiye, and analyzed using Structural Equation Modeling (SEM). The results show that IP significantly increases MP, which in turn reduces life satisfaction and increases workaholism and turnover intention. Additionally, IP was found to be more prevalent among men and less experienced healthcare professionals, particularly resident physicians. By empirically confirming MP as the central mediator between IP and its detrimental outcomes, this study advances theoretical understanding of psychological strain in high-pressure healthcare environments. It also provides practical guidance for healthcare organizations, suggesting that early interventions and institutional awareness strategies, such as mentorship programs and feedback systems, can help mitigate perfectionism-driven risks and support workforce well-being while sustaining high-quality patient care.
