O impacto de experiências adversas na infância sobre o desenvolvimento psicológico adulto é um tema central na investigação contemporânea. Este estudo teve como objetivo explorar a relação entre trauma na infância, maquiavelismo e crescimento pós-traumático (CPT), bem como avaliar o papel mediador do CPT na relação entre o trauma e o maquiavelismo. Participaram 218 indivíduos, através do preenchimento de um questionário online, que incluiu a escala Mach-IV — validada para a população portuguesa no presente estudo — o Childhood Trauma Questionnaire – Short Form (CTQ-SF) e o Posttraumatic Growth Inventory – Short Form (PTGI-SF). A análise fatorial confirmatória da Mach-IV revelou uma estrutura bifatorial ajustada após a eliminação de seis itens, com consistência interna moderada. Os resultados mostraram uma correlação positiva e significativa entre trauma e maquiavelismo. Por outro lado, não foi encontrada uma correlação significativa entre o trauma e o crescimento pós-traumático, embora a subescala de negligência física tenha previsto o CPT. A análise de mediação indicou, por sua vez, que o CPT medeia parcialmente a relação entre negligência física e maquiavelismo. Estes resultados ressaltam a complexidade das respostas adaptativas e desadaptativas ao trauma precoce e reforçam a necessidade de intervenções que promovam o crescimento psicológico após experiências adversas.
The impact of adverse childhood experiences on adult psychological development is a central topic in contemporary research. This study aimed to explore the relationship between childhood trauma, Machiavellianism and posttraumatic growth (PTG), as well as to assess the mediating role of PTG between trauma and Machiavellian traits. A total of 218 participants completed na online questionnaire, which included the Mach-IV scale — validated for the Portuguese population in this study — the Childhood Trauma Questionnaire – Short Form (CTQ-SF), and the Posttraumatic Growth Inventory – Short Form (PTGI-SF). Confirmatory factor analysis of the Mach-IV revealed na adjusted two-factor structure after removing six items, with moderate internal consistency. Results showed a significant positive association between childhood trauma and Machiavellianism. Conversely, no significant association was found between trauma and PTG, although the physical neglect subscale predicted PTG. Mediation analysis indicated that PTG partially mediates the relationship between physical neglect and Machiavellianism. These findings highlight the complexity of adaptive and maladaptive responses to early trauma and underscore the need for interventions that foster psychological growth following adverse experiences.
