Περίληψη:	Self-talk is a cognitive construct that has received increasing research attention in sport, particularly in recent years. A contemporary, theory-based conceptualization of self-talk in sport has recognized two distinct self-talk entities. The first entity, organic self-talk, refers to self-talk as inherent self-statements athletes address to themselves during their sport participation. The second self-talk entity strategic self-talk reflects self–talk as a deliberately mental strategy, determined before sport participation, whereby specific cues words or phrases are employed with the aim of enhancing performance or achieving other related performance outcomes. Athletes’ organic self-talk is further distinguished between spontaneous self-talk, a more uncontrolled type of self-talk, and goal-directed self-talk, a more controlled type of self-talk. However, these contemporary organic self-talk distinctions between spontaneous and goal-directed self-talk have not yet been operationalized, to allow assessment suitable for quantitative research. Therefore, based on this contemporary, theory-based conceptualization of self-talk in sport, a first aim this PhD was to develop and test the psychometrics properties of a theory-based instrument, the Organic Self-Talk Questionnaire for Sport (OSTQS), assessing the content and the structure of athletes’ organic, spontaneous and goal-directed self-talk) on a state level during sport participation. Utilizing this new scale, a second aim of this PhD was to investigate the factors that shape athletes’ organic, spontaneous and goal-directed self-talk on a state level during sport participation. Overall, this PhD consists of three different articles. The first article is a literature review that aimed to classify and reinterpret previous research findings on the antecedents of athletes’ organic self-talk, in terms of the contemporary distinctions between spontaneous and goal-directed self-talk. The article also provides directions for future research and based on the existing research evidence presents interventions that could be implemented at antecedents of athletes’ organic self-talk, to change athletes’ organic self-talk in effective directions The second article outlines the development of OSTQS, a new, theory-grounded, self-report measure, designed to assess the content and the structure of athletes’ organic self-talk spontaneous and goal-directed self-talk on a state level during sport participation. Two studies were conducted. In the first qualitative study, a prospective 60-item measure was developed based upon (a) the operational definitions of athletes’ spontaneous and goal-directed self-talk in sport and (b) raw data collected from athletes in this study through open-ended questionnaires and semi-structured interviews. In the second quantitative study, the psychometric properties of the developed questionnaire were tested through examination of factorial, convergent, and discriminant validity, and reliability. Confirmatory factor analyses (CFA revealed an adequate fit of a 17-item four-factor correlated model for spontaneous self-talk and a 28-item seven-factor correlated model for goal-directed self-talk, and (b) the superiority of these models over to their respective single-factor and hierarchical models, supporting therefore respectively the factorial and convergent validity of the OSTQS. Discriminant validity and reliability analyses provided further evidence regarding the psychometric integrity of the new measure. Overall, these results suggest that the OSTQS is a valid and reliable scale that could aid us further enhancing our understanding regarding athletes’ organic self-talk, its antecedents, and its consequences. Finally, the third article includes a quantitative study aimed to examine the nomological validity of OSTQS, and whether a) the big five personality traits as personal antecedents, and b) athletes’ Basic Psychological Needs (BPNs ) satisfaction and frustration within their sport environment, as social-environmental antecedents would predict athletes’ organic, spontaneous and goal-directed self-talk .The results supported the nomological validity of OSTQS and indicated the incremental contribution of BPNs satisfaction and frustration to the prediction of athletes’ organic, spontaneous and goal-directed self-talk, over and above athletes’ big five personality traits and BPNs satisfaction respectively. Overall, the present research provides a theory-based, valid and reliable, state scale assessing athletes’ organic, spontaneous and goal-directed self-talk and underlines the meaningfulness of social-environmental factors on the formulation of athletes’ organic, spontaneous and goal-directed self-talk at the state level, over and above personality traits which are considered relatively stable, and thus are more difficult to be changed via interventions
