  abstract  = {In this paper the psychometric quality of the sport-specific Volitional Components Questionnaire (VKS) is examined. After an item analysis, a factor analysis was undertaken resulted in the four factors self optimization, lack of activation, loss of focus, and self impediment. The questionnaire exhibits satisfactory internal consistency (Cronbach's alpha) and retest reliability. In line with theory (Kuhl, 2001), correlations with the general questionnaire VCQ II (Kuhl \& Fuhrmann, 1998) and sport-specific action orientation as measured with the HOSP questionnaire (Beckmann, 2003) indcate construct validity. Validity can also be shown by correlations with the external criterion of expert rating by coaches. In addition, the VKS is able to differentiate between athletes who perform well and those who perforin poorly.},
