The coach-rating scale for Achievement-Motivated Behavior in Individual Sports (AMBIS-I) was constructed to measure achievement motivation, not from athletes' own views but from coaches' perspectives. The tool was already checked for reliability as well as content, factorial, and concurrent criterion validity (Zuber and Conzelmann, 2019). To further establish construct and criterion validity, two different samples were involved. Sample 1 included 67 experienced coaches rating their 278 athletes on the three AMBIS-I dimensions proactivity, ambition and commitment. In sample 2, 157 athletes completed self-report questionnaires measuring motivational and volitional concepts. Congruent and discriminant construct validity were assessed using the QCV-procedure (Westen and Rosenthal, 2003) by comparing experts' predicted and empirically observed correlations between the coaches' ratings on the AMBIS-I with the self-ratings of validated instruments. Consistent with theoretical expectations, achievement goal orientations, self-determination and self-optimization show significant positive relationships to the AMBIS-I scales, the negatively formulated volitional concepts, negative ones. As indicated by the 0.87 ≤ ≤ 0.95, the general patterns of the expert's predictions triangulate consistently with the observed correlations. The findings concerning absolute agreement were mixed. Even though the ICCs suggest sufficient to good consistency, the values of are considerably lower. To indicate criterion validity, AMBIS-I display medium to large correlations with the actual performance level estimated by the coaches and small to medium correlations with the assigned potential for subsequent success one year later. In summary, we found solid indications, that AMBIS-I is a valid measure of achievement-motivated behavior in individual sports from coaches' perspective.
《个体运动成就动机行为教练评定量表》（AMBIS-I）是为了从教练的角度而不是运动员的自身观点来衡量成就动机而构建的。该工具已经经过了可靠性以及内容、因子和同时效标准效度的检验（Zuber 和 Conzelmann，2019）。为了进一步建立结构和效标效度，涉及了两个不同的样本。样本 1 包括 67 名经验丰富的教练，他们对 278 名运动员在 AMBIS-I 的三个维度上的积极性、野心和承诺进行了评定。在样本 2 中，157 名运动员完成了自我报告问卷，测量了动机和意志概念。使用 QCV 程序（Westen 和 Rosenthal，2003）通过比较专家预测的和经验观察到的教练在 AMBIS-I 上的评分与验证工具的自我评分之间的相关性，来评估一致和区分结构效度。与理论预期一致，成就目标取向、自我决定和自我优化与 AMBIS-I 量表呈显著正相关，而与消极制定的意志概念呈负相关。正如 0.87 ≤ ≤ 0.95 所示，专家预测的总体模式与观察到的相关性一致地三角化。关于绝对一致性的发现参差不齐。尽管 ICC 表明一致性足以好，但 的值要低得多。为了表明效标效度，AMBIS-I 与教练估计的实际表现水平呈中等至大的相关，与一年后后续成功的预期潜力呈小至中等的相关。总的来说，我们发现了有力的证据表明，从教练的角度来看，AMBIS-I 是衡量个体运动中成就动机行为的有效工具。
