Achievement-Motivated Behavior in Individual Sports: Evidence for the Construct and Criterion Validity of the AMBIS-I Coach-Rating Scale

Table 3. ICCs, r_alerting-CV and r_contrast-CV to define construct validity patterns of observed and predicted correlations between coach-ratings of AMBIS-I and the self-report questionnaires at t₁ (n = 193).
