Psychological capital bolsters motivation, engagement, and achievement: Cross-sectional and longitudinal studies

Psychological capital (PsyCap) has been widely investigated in the organizational context. However, limited attention has been given to the role of PsyCap in the academic setting. The primary objective of this study was to examine how PsyCap is associated with academic motivation, engagement, and achievement using both cross-sectional (Study 1) and longitudinal (Study 2) approaches. Study 1 revealed that PsyCap was associated with higher autonomous motivation and controlled motivation even after controlling for relevant demographic variables. PsyCap was also associated with lower levels of amotivation. Study 2 showed that PsyCap was both a concurrent and prospective predictor of autonomous motivation, controlled motivation, academic engagement, and academic achievement even after controlling for their respective autoregressors and other relevant covariates. Mediational analyses indicated that the effects of T1 PsyCap on T2 achievement and T2 engagement were mediated by T2 autonomous motivation. The theoretical and practical implications are elucidated.
