The Effects of Rational Emotive Behavior Therapy and Motivational Interviewing on Emotions, Automatic Thoughts, and Perceived Performance of Elite Female Volleyball Players
(Elsevier, 2023) Urfa, O.; Asci, F. H.
Objectives: The aim of this study was to examine the effect of Rational Emotive Behavior Therapy intervention alone (REBT-A) or with motivational interviewing (REBT + MI) on the emotions, automatic thoughts, and perceived performance of elite female volleyball players. Design: and method: Single-case, staggered multiple-baseline AB and ABC designs were adapted in the study. Five female volleyball players participated in the study, of which three players participated in the REBT-A and two players participated in the REBT + MI. The athletes were competing in the national volleyball league (Mage = 28, SD = 5.52). All participants were elite athletes with at least ten years of sports experience. Three scores (T1, T2, T3) were calculated for the athletes' perceived performance, emotion, and automatic thoughts. T1 was the baseline score calculated before the sessions. T2 was calculated after the first two sessions (the first three sessions for REBT + MI) and T3 was calculated after the last three sessions. In the data analysis, percentage changes, effect size, and visual analyzes were used in the T1, T2, and T3 scores. Results: REBT-A and REBT + MI interventions increased perceived performance, positive emotions, and positive automatic thoughts, and decreased negative emotions and negative automatic thoughts. REBT + MI was more advantageous than REBT-A in increasing positive emotion, positive automatic thought, and perceived performance. Conclusions: As a result, REBT alone or with motivational interviewing has a positive effect on perceived performance, emotions, and automatic thoughts, but REBT + MI has greater potential to increase positive constructs.

The Psychometric Properties of Body-Related Self-Conscious Emotion Measures for Turkish Adolescents: Esem and Cfa Approaches
(Springer, 2025) Urfa, O.; Aşçı, F.H.
The aim of this study was to investigate the psychometric properties of the “Body and Appearance Self-Conscious Emotions Scale (BASES)” and “Body and Fitness-Related Self-Conscious Emotions Scale (BSE-FIT)” for Turkish adolescents. Each scale consists of 16 items and four subscales (shame, guilt, authentic pride, and hubristic pride) and items are responded on 5-point Likert scale. The psychometric properties of BASES and BSE-FIT were tested on 332 girls and 264 boys, a total of 596 participants (Mage=13.88, SDage=1.92). Confirmatory factor analysis (CFA) and exploratory structural equation modelling (ESEM) with multi-group analysis (MGA) were used to test the 4-factor and 2-factor structures and measurement invariance. Cronbach’s alpha internal consistency coefficient and composite reliability (CR) were calculated for reliability. According to the model fit indices and factor loadings, the most appropriate model was the 4-factor CFA model for BASES and BSE-FIT. Cronbach’s alpha and CR coefficients were 0.79 and above in the 4-factor CFA structures of both scales. In addition, MGA demonstrated factor structures, factor loadings, intercepts, and measurement error variance of BASES and BSE-FIT were equivalent according to sex, school level, sport status, region, and body mass index. In conclusion, BASES and BSE-FIT are valid and reliable in Turkish adolescents, and both scales provided measurement invariance in adolescents with different demographic characteristics. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2025.
