    Cross-Cultural Validation of the Short Form of the Physical Self Inventory (PSI-S)
    (Amer Psychological Assoc, 2018) Morin, Alexandre J. S.; Maiano, Christophe; Scalas, L. Francesca; Asci, F. Hulya; Boughattas, Wissal; Abid, Sami; Probst, Michel
    The study examined the cross-cultural validity of the short form of the Physical Self-Inventory (PSI-S) among samples of adolescents speaking French, Dutch, Turkish, Italian, and Arab. A total of 4,867 adolescents (1,173 Belgian Flemish, 598 French, 1,222 Italian, 643 Turkish, 646 Kuwaiti, and 585 Tunisian) completed the original PSI-S version, and a revised version including a positively worded reformulation of the 3 negatively worded PSI-S items. The results supported the factor validity and reliability of revised PSI-S version across all cultural groups, and its superiority when compared to the original version. Compared with confirmatory factor analyses, relying on an exploratory structural equation modeling measurement model resulted in superior solution, and in more cleanly differentiated factors. PSI-S responses proved to be fully invariant across cultural groups, and presented no evidence of differential item functioning as a function of age, gender, body mass index (BMI), and sport involvement. However, the results revealed meaningful mean level differences as a function of gender, age, sport involvement, and BMI that were mostly consistent with the results from previous studies.

    Roles of Perceived Motivational Climates Created by Coach, Peer, and Parent on Dispositional Flow in Young Athletes
    (Sage Publications Inc, 2017) Caglar, Emine; Asci, F. Hulya; Uygurtas, Murat
    We investigated the contribution of perceived motivational climates created by coach, peer, and parent on the dispositional flow experience of young athletes. Eighty-six female (M-age=14.24, SD=1.38 years) and 134 male (M-age=16.28, SD=1.17 years) athletes completed questionnaires of perceived motivational climates created by coach, peer, and parent and the Dispositional Flow Scale-2. Results of hierarchical multiple regression analyses indicated that perceived task-involving coach (=.40, p<.001) and peer (=.28, p<.002) motivational climates were the only significant predictors of dispositional flow. These findings suggest that task-involving motivational climates should be strengthened to increase experience of flow.

    Validity and reliability of the Very Short form of the Physical Self-Inventory among Turkish adolescents
    (Taylor & Francis Ltd, 2017) Asci, F. Hulya; Maiano, Christophe; Morin, Alexandre J. S.; Caglar, Emine; Bilgili, Naile
    The study aimed to test the validity and reliability of the Very Short form of the Physical Self-Inventory (PSI-VS) among a sample of 635 Turkish adolescents. These adolescents have completed the 12 original items of the PSI-VS, plus a positively worded reformulation of the single reverse-keyed item of the physical attractiveness subscale. A series of confirmatory factor analyses was used to examine the psychometric properties of the original and modified versions of the PSI-VS. Findings revealed superior psychometric properties with the modified version than with the original set of items. The modified version was thus subsequently used to examine its factor structure invariance across sexes, age groups and sport practice involvement. Results not only report that this version was fully invariant across, but also that latent means were significantly different across sexes and sport practice involvement. In sum, the Turkish modified version of the PSI-VS presents acceptable psychometric properties and may be used to repeatedly and/or intensively assess participants' physical self-perceptions in the context of sport and exercise interventions.
