Achievement motivation has been identified as a relevant criterion to assess athletic talent. In the context of talent selection
decisions, the popular use of self-report questionnaires has presented higher risks of social desirability. Consequently,
a shift towards more robust methods such as the assessment of achievement-motivated behavior with the coach-rating
scale achievement-motivated behavior in individual sports was suggested.1 The purpose of this study was to adapt and
validate this assessment from individual to team sports, involving 48 German-speaking coaches examining the achievement-
motivated behaviors of their 527 youth athletes as well as the self-ratings of 250 athletes. The achievement-motivated
behavior in team sports was found to display a good fit with the observed data (e.g., CFI=.98; RMSEA =.04) and to
measure reliably the factors proactivity, ambition, and commitment with 12 items (test–retest reliability rtt ≥.75;
Cronbach’s alpha α ≥ .80 for all scales). With the exceptions of the proactivity scale for interrater reliability, the commitment
scale for concurrent criterion validity and the ambition scale for construct validity, psychometric properties
were found satisfactory. The use of averaged ratings of two evaluating coaches is recommended to reduce possible
bias in the assessment of achievement-motivated behaviors in team sports.
