The retention of all the SMTQ items was followed by further examination of the PCA results.
Although the SMTQ has been developed and validated previously (Sheard et al.
Compared to the original SMTQ items included on each factor, the present results differ in several ways.
The SMTQ was previously validated using samples of competitive athletes from a range of sports (26 different sports), whereas this study solely included competitive tennis players.
Perhaps these distinctions also apply to MT, with the possibility that certain aspects of MT, as it applies to South Africa, are not included on the SMTQ, and, as a result, were not examined in this study.
In addition, Crust and Swann (2011) suggested that the some of the SMTQ subscale internal consistency scores denoted that certain subscales were assessing more than one construct of MT.
Although certain items loaded differently in this study as compared to the original SMTQ subscales, a number of the items were retained on their original scales.
As denoted, the subscale terms exhibit conceptual overlap with the original SMTQ subscales, except for the subscale of constancy, which was not adjudicated as an appropriate label for any of the factors revealed in this study.
Although the third factor, positive perspective, has limited similarity with the original SMTQ subscales, it does possess some degree of congruence with Clough et al.
The purposes of this study were to determine the degree to which four elite level (NCAA Division 1) college tennis coaches and their respective athletes agreed: (a) on the importance of various characteristics of MT in tennis, (b) on the importance of each item on an inventory-the modified SMTQ (the IMTQ)--that measures and describes components of MT, and (c) on the extent to which each athlete possessed characteristics of MT.
Finally, the use of a pre-established measure of MT, the SMTQ, may have restricted the information generated about coaches' and athletes' perceptions of MT and ratings of the importance of posited constituents of MT.
