This study assessed the hormonal and psychological responses to a free-throw shooting competition in twelve NCAA Division I female collegiate basketball players. Salivary cortisol, alpha-amylase, and testosterone were collected before and after the competition, in addition to a self-reported measure of anxiety. Using nonparametric statistics, cortisol (Z = –3.06, p = .002) and testosterone (Z = –2.67, p = .008) levels were significantly higher precompetition compared with postcompetition. There were no statistically significant differences between winners and losers for anxiety or hormone responses. Concentration disruption (rho = .63, p = .03) and total competitive anxiety (rho = .68, p = .02) were positively correlated with precompetition cortisol. Concentration disruption also correlated positively with postcompetition cortisol (rho = .62 p = .03) and postcompetition testosterone (rho = .64, p = .03). Future studies are needed to examine the psychological and physiological stress responses of basketball players during different competition tasks.

This study aimed to provide further psychometric validation of the Sport Anxiety Scale-2 (SAS-2) by assessing the factor structure, invariance across gender, and convergent and divergent validity of the SAS-2 by correlating both related (i.e., anxiety sensitivity, brief fear of negative evaluation, intolerance of uncertainty, and negative affect) and unrelated constructs (i.e., positive affect, self-confidence). A total of 542 current and former competitive athletes completed a questionnaire through Amazon’s Mechanical Turk system. All data were collected via online survey. Participants were randomly assigned to an exploratory factor analysis (n = 271) and confirmatory factor analysis group (n = 271). Results indicated that both exploratory and confirmatory factor analyses supported the three-factor model of anxiety involving somatic anxiety, worry, and concentration disruption. Additionally, this study found the SAS-2 to be reliable, gender invariant, and have strong construct validity. Our findings extend the generalizability of the SAS-2 in more varied populations of athletic backgrounds.
