Protein supplementation often refers to increasing the intake of this particular macronutrient through dietary supplements in the form of powders, ready-to-drink shakes, and bars. The primary purpose of protein supplementation is to augment dietary protein intake, aiding individuals in meeting their protein requirements, especially when it may be challenging to do so through regular food (i.e. chicken, beef, fish, pork, etc.) sources alone. A large body of evidence shows that protein has an important role in exercising and sedentary individuals. A PubMed search of “protein and exercise performance” reveals thousands of publications. Despite the considerable volume of evidence, it is …

Serve-Specific Core Self-Evaluations: A Predictive Validation Study, Brandi Renee Forgione Apr 2021

Serve-Specific Core Self-Evaluations: A Predictive Validation Study, Brandi Renee Forgione

Masters Theses & Specialist Projects

Core Self-Evaluations (CSE) is a broad personality trait used by industrial organizational psychologists to predict important organizational outcomes such as job performance and employee satisfaction. CSE comprises four elements: generalized self-efficacy, self-esteem, locus of control, and neuroticism. Task-specific versions of CSE have been proposed to better predict task-specific performance than general CSE. Accordingly, Serve-Specific Core Self- Evaluations (SS-CSE) was adapted specifically to predict serve performance of intercollegiate volleyball players. In this study, I explored the predictive validity of SS-CSE for serve performance by expanding a previous study that used a concurrent validation approach.
