Mental toughness in sport: A review; [Mentale Toughness im Sport: Ein Review]

The present article reviews the previous literature on mental toughness in sport. The review demonstrates that qualitative researchers have been able to establish conceptual clarity and provide guidance for operationalizing the concept. As a consequence, several quantitative questionnaires have been developed beyond the Psychological Performance Inventory (PPI). Meanwhile, there is preliminary evidence for the validity and reliability of these instruments. Moreover, researchers showed that mental toughness is associated with higher achievement levels or performance outcomes in elite athletes. Regarding the underlying mechanisms, prior research indicated that mentally tough athletes use more positive coping strategies. Although researchers agree that mental toughness is a rather stable construct, experimental research showed that mental skill training influenced mental toughness in a positive fashion. To date, there is a great need for more quantitative, longitudinal and experimental research. Also, a biopsychological approach offers an interesting avenue for future studies. © 2011 Springer-Verlag.
