This study’s main purpose was understanding the impact of psychological capital on affective commitment and job engagement. For this objective, responses from 206 employees from different industries and various occupations were collected with a two-phased questionnaire. The results showed that psychological capital had an important influence on affective commitment and job engagement along with a strong relationship with workplace support. Furthermore, there was the full mediation effect of psychological capital between perceived organizational support, supervisor support, coworker support and job engagement.
