    Psychometric properties of Physical Self Inventory Turkish version among university students
    (CUMHURIYET UNIV TIP FAK PSIKIYATRI ANABILIM DALI, 2017) AŞÇI, FEVZİYE HÜLYA; Caglar, Emine; Asci, F. Hulya; Bilgili, Naile
    The purpose of this study was to test the validity and reliability of the Turkish version of Physical Self Inventory (PSI) among university students. Methods: One hundred and eighty-seven females and 106 males, totally 293 university students (Mean age 21.97 +/- 1.71 years) participated in this study. The Turkish version of PSI, Physical Self-Description Questionnaire (PSDQ), and Social Physique Anxiety Scale (SPAS) were administered to participants in a group setting. Confirmatory factor analysis (CFA) was used to test construct validity of PSI-Turkish version. In addition, Pearson correlation coefficients were calculated to see relationships between PSI-Turkish and PSDQ subscales for concurrent validity and between PSI-Turkish subscales and SPAS for convergent validity. Cronbach's alpha coefficients were calculated to determine reliability. Results: CFA results provided good fit index values for the model with 24 items indicating similar factor structure with the original scale's six-factor structure. In terms of concurrent validity, it was found positive and statistically significant relationships between PSI-Turkish and PSDQ subscales ranging from 0.65 to 0.84. In addition, statistically significant and negative correlation coefficients were found between social physique anxiety and PSI-Turkish subscales, showing convergent validity. These coef- ficients ranged from -0.23 (physical strength) to -0.45 (physical attractiveness). These findings revealed that concurrent and convergent validities of the PSI-Turkish were supported. Internal consistency coefficients of the PSI-Turkish subscales ranged from 0.55 (physical attractiveness) to 0.89 (sport competence). Conclusion: It can be concluded that PSI-Turkish version is a valid and reliable instrument to measure physical self-perception. (Anatolian Journal of Psychiatry 2017; 18(6): 594-601)

    Short Versions of Turkish Flow Scales for Athletes: Reliability and Validity Study
    (SLOVAK ACAD SCIENCES INST EXPERIMENTAL PSYCHOLOGY, 2020-10-06) AŞÇI, FEVZİYE HÜLYA; Caglar, Emine; Sari, Ihsan; Asci, F. Hulya; Eklund, Robert C.; Jackson, Susan A.
    The purpose of this study was to test the validity and reliability of the Short Flow State Scale-2 (SFSS-2) and Short Dispositional Flow Scale-2 (SDFS-2) for Turkish athletes in two separate studies. One hundred ninety-seven athletes (M-age = 22.05, SD = 3.60) voluntarily participated in the first study to test the psychometric properties of SDFS-2 and completed SDFS-2, Long Dispositional Flow Scale-2, and Sport Motivation Scale. In the second study, 423 athletes (M-age = 20.00, SD = 3.46) constituted the sample group and completed SFSS-2, Flow State Scale2, and Situational Motivation Scale for testing the psychometric properties of SFSS-2. Factor structures of both scales were examined by confirmatory factor analysis (CFA). Concurrent validity of the scales was examined by Pearson Product Moment Correlation analysis. The reliability evidence was obtained by a Cronbach's alpha values. The results of CFA from both studies revealed that both scales have nine items with one factor. All the correlation coefficients calculated for concurrent and convergent validity were significant (between 0.45-0.92 for SDFS-2 and 0.33-0.79 for SFSS-2). Cronbach's alpha coefficients calculated for internal consistency were 0.77 for SDFS-2 and 0.82 for SFSS-2. The results from both studies indicated that Turkish versions of SDFS-2 and SFSS-2 are valid and reliable instruments to be used in sports contexts.
