Validation of the Coach Behavior in Sports Questionnaire: Towards dynamic assessments using the circumplex model for coach behavior.

The development of the circumplex model for coach behavior recently provided researchers an integrative model to assess coach behavior. While the circumplex model has currently only been deployed in cross-sectional research designs using the Situations in Sports questionnaire (SISQ), it has clear potential within research on dynamics of coach behavior. However, the SISQ consists of vignette-based situations and is too extensive for such frequent administrations. Within the present study we therefore developed the Coach Behavior in Sports Questionnaire (CBSQ), a 32-item alternative for the SISQ which consists of general items rather than vignette-based situations. First, content validity of 54 initial pilot CBSQ items was tested in a sample of 34 expert coaches. Second, construct validity, predictive validity, and reliability of the 32-item CBSQ was tested in a sample of 689 athletes and 420 coaches. Third, within-person variability of coach behavior was longitudinally assessed using the 32-item CBSQ during a five-week training and game period in a sample of 31 coach-athlete dyads. The 32-item CBSQ showed to be a valid and reliable alternative for the SISQ. Also, coach behavior showed considerable within-person variability over the five-week period in all coaching styles and approaches. Additionally, a 24, 16, and 12-item version were tested to provide even shorter alternatives. The CBSQ opens new horizons for future longitudinal research and coach reflection programs based on the circumplex model for coach behavior.

Can participative coach behaviour be perceived as controlling? The role of athletes' expectations.

ABSTRACTCoach-rated participative behaviour has already been related to beneficial outcomes in athletes. Yet, research also indicates that allowing participation is not straightforward as it can sometimes be perceived as controlling or can even result in maladaptive outcomes. Building on implicit leadership theory, this study investigated the role of the alignment between coach-rated participation and athletes' expectations for participation in developing perceptions of domineering coach behaviour in athletes, a specific type of controlling coach behaviour. A secondary goal was to explore this relation in higher and lower level teams separately. Athletes' expectations for participative coach behaviour, coach-rated participative behaviour and athletes' perceptions of domineering coach behaviour were measured in 61 team sport coaches and 654 athletes competing in football, volleyball, basketball, and handball competitions. Using polynomial regression with response surface analysis and controlling for athletes' sport experience, overall, results showed that a discrepancy between coach-rated participation and athletes' expectations for participation was related with increased perceptions of domineering coach behaviour in athletes with more than 5 years of experience. However, in lower level teams, high amounts of participation seem optimal as only less coach-rated participation than expected predicted increased perceptions of domineering coach behaviour in athletes with more than 15 years of experience. This in contrast with higher level teams where, independent of athletes' experience, both more and less coach-rated participation than expected were related with increased perceptions of domineering coach behaviour in athletes. Current findings stress the need for a situation specific approach when offering participation to optimize its effectiveness.

A discrepancy between coach-rated participation and athletes' expectations for participation was related with increased perceptions of domineering coach behaviour in team sport athletes with more than 5 years of experience,In lower level teams, only less participation than expected leads to increased perceptions of domineering coach behaviour in athletes with more than 15 years of experience,In higher level teams, both more and less participation than expected were related with increased perceptions of domineering coach behaviour in athletes,Coaches should try to get informed about the expectations of their athletes and inform their athletes about the reasons of their behaviour to manage athletes' expectations.
