Team mental model (TMM) has been introduced from organizational and industrial psychology to sport psychology. Team mental models are defined as a "team members' shared, organized, understanding and mental representation of knowledge about key elements of the team's relevant environment" (Mohammed & Dumville, 2001, p. 90). One of the currently used TMM measurement questionnaires is the Team Assessment Diagnostic Measure (TADM). However, items seem similar to the construct of cohesion. Therefore, the purpose of this study was to analyze multicollinearity between the TADM and the Youth Sport Environment Questionnaire.
89 male youth soccer players in Calgary Minor Soccer Association, Calgary, Alberta, Canada for age between 13 and 17 years old.
Team mental model: Team Assessment Diagnostic Measure (TADM)
Cohesion: Youth Sport Environment Questionnaire (YSEQ)
Pearson correlation analysis was conducted.
All subscales and total mean scores of YSEQ and TADM were significantly moderately and highly correlated positively (r = 0.44 - 0.81, p < 0.01). Specifically, the mean of task cohesion was highly correlated to mean of team mental models (r = 0.81).
As the correlation coefficient did not reach 0.90, we could not conclude that YSEQ and TADM exhibited multicollinearity. However, task cohesion of YSEQ and mean of TADM was still highly correlated (r = 0.81). If there are operational overlaps between TMM and task cohesion, it becomes questionable what, in fact, is being measured. Therefore, the TADM should be used carefully, and another methodology such as Pathfinder is recommended.
