Divergent/Discriminant
Divergent validity has not been assessed to-date.
Construct/Factor Analytic
Separate confirmatory factor analyses were conducted on the two samples described above ( Beattie et al.,
2011). Both demonstrated that a single latent factor provided a good fit to the data and did not differ significantly
with respect to model fit from a two-factor model. Sample 1 fit: S-B χ2
545115.00, CFI 5.97, RMSEA 5.07,
SRMR 5.05; Sample 2 fit: S-B χ2
20529.36, CFI 5.97, RMSEA 5.05, SRMR 5.04.
Criterion/Predictive
TROSCI scores obtained five days prior to sporting competition were significantly and negatively correlated
with state confidence variability leading up to competition ( r5/C0.37,p,.01). Furthermore, these TROSCI scores
predicted post competition state confidence incrementally over state confidence measured one hour prior to com-
petition and a measure of performance experience measured immediately post competition (from /C035perform
much worse than usual ;t o135perform much better than usual ).

Results and Comments
The TROSCI is a short, well-constructed scale that lends itself to adaptation for the study of confidence in
other specific domains. Given its novelty, further investigation regarding its incremental utility over existing
scales, such as the Trait Sports Confidence Inventory (below) is recommended before using it in isolation.
Furthermore, considering the large proportion of male athletes used in its construction, a larger female sample
will be needed to examine gender differences.
TRAIT-ROBUSTNESS OF SELF-CONFIDENCE INVENTORY
Please read the instructions carefully before responding to the statements.
Think about your confidence and how your performance may affect your confidence generally .
The statements below describe how you may feel generally about your confidence, answer each statement by cir-
cling the number that corresponds to how strongly you agree or disagree generally . Please try and respond to each
item separately.
The terms competition refers to matches, tournaments or other competitive events.
Please answer the item as honestly and accurately as possible. There are no right or wrong answers. Your
response will be kept confidential.
Each question is accompanied by the following rating scale:

A bad result in competition has a very negative effect on my self- confidence.*
My self-confidence goes up and down a lot.*
Negative feedback from others does not affect my level of self-confidence.
If I perform poorly, my confidence is not badly affected.
My self-confidence is stable; it does not vary much at all.
My self-confidence is not greatly affected by the outcome of competition.
If I make a mistake it has quite a large detrimental effect on my self-confidence.*
My self-confidence remains stable regardless of fluctuations in fitness level.
