Strengthening the assessment of self-talk in sports through a multi-method approach.

Although self-talk during competitive sports is common and predictive of athletes' motivation, experiences, and performance, it is difficult to accurately assess self-talk. An important, yet underexplored, next step in the assessment of self-talk is to rely on a multi-method approach. The present study sought to examine whether tennis players' self-talk assessed either via self-reports or via a live-recorded procedure would relate to each other. Competitive tennis players (N = 120; Mage  = 25.22; SDage  = 9.82) were asked to perform multiple tennis exercises while verbalizing their thoughts, which were audio-recorded and subsequently coded. Prior to exercise engagement, they indicated their fear of failure, while, after exercise engagement, they reported on their experienced pressure and self-talk using questionnaires. There was substantial correspondence between the coded and self-reported measure, allowing the estimation of a latent factor representing a multi-method assessment of self-talk. Moreover, in a theory-consistent way, both latent factors representing negative and positive self-talk were related to a hypothesized antecedent (ie, fear of failure), with negative self-talk also relating to a hypothesized consequence (ie, perceived pressure). Overall, the present study shows that athletes' self-talk can be measured reliably through different methods. Guidelines for the assessment of self-talk in future research are provided.
