Öğe Cross-cultural adaptation of the intuitive eating scale-2: psychometric evaluation in a sample in Turkey(Springer, 2021) Akirmak, Umit; Bakiner, Egenur; Boratav, Hale Bolak; Guneri, GulinIntuitive eating is the ability to eat in response to physiological hunger and satiety cues rather than to external or emotional cues. The purpose of this research was to adapt the Intuitive Eating Scale-2 (IES-2; Tylka and Kroon Van Diest 2013) to Turkish in an adult sample. The factor structure of the IES-2 was evaluated in Study 1 (n = 264) with exploratory factor analysis (EFA), and in Study 2 (n = 271) with confirmatory factor analysis (CFA). Additionally, the correlations of the IES-2 scores with measures of self-esteem, disordered eating, obsessive thoughts, and body anxiety in social situations were assessed in Study 1 to evaluate the scale's convergent validity. EFA results supported the four-factor structure of the original scale with the following factors: eating for physical rather than emotional reasons (EPR), unconditional permission to eat (UPE), reliance on hunger and satiety cues (RHSC), and body-food choice congruence (BFCC). Intercorrelations between the IES-2 total scores and other study constructs were in the expected direction, and ranged from medium to large. CFA results yielded acceptable fit values and supported the 4-factor model of the original scale. A second-order CFA showed that UPE had no association with the second-order latent variable, Intuitive Eating. The results suggest that the IES-2 is a valid and reliable measure of intuitive eating for the adult population in Turkey. Furthermore, it is recommended that Turkish IES-2 total scores be computed without the UPE items. The findings and clinical implications are discussed, and suggestions for future research in other cultural contexts are provided.Öğe Cross-Cultural Adaptation of the Intuitive Eating Scale-2: Psychometric Evaluation in a Sample in Turkey (vol 40, pg 1083, 2021)(Springer, 2021) Akirmak, Umit; Bakiner, Egenur; Boratav, Hale Bolak; Guneri, GulinThe original version of the article unfortunately contained an error.

A conservation of resources perspective(Pergamon-Elsevier Science Ltd, 2021) Akirmak, Umit; Ayla, PinarResearch on time perspective has not been reliably applied to organizational settings primarily because there have not been attempts to empirically and theoretically link time perspective to job attitudes. We utilized the framework of conservation of resources theory (COR) and assumed that time perspective is a valuable personal resource that buffers the adverse effects of burnout leading to more favorable job appraisals. Measures of time perspective, core self-evaluations, burnout and job satisfaction were collected from 135 bank employees. We replicated the indirect effect of core self-evaluations on job satisfaction through burnout and further showed that participants with a more balanced time perspective had lower burnout leading to higher job satisfaction. These results suggest the importance of time perspective in job attitudes and provide insights into enhancing human strengths from a positive psychology perspective. We argued for a connection between the COR and time perspective theories based on motivation and goal attainment processes and further discussed the implications of our findings.Öğe How is Time Perspective Related to Perceptions of Self and of Interpersonal Relationships?(Cambridge Univ Press, 2014) Akirmak, UmitPrevious research has revealed a positive association between balanced time perspective (BTP) and subjective well-being (Boniwell & Zimbardo, 2004), however mechanisms underlying BTP are yet to be determined. The goal of the present study was to examine the contributions of personality and quality of interpersonal relationships in the development of BTP. Additionally, the correlations between these measures and time perspective dimensions were evaluated as an attempt to provide further psychometric properties of the Zimbardo Time Perspective Inventory (ZTPI) in a Turkish sample. 178 undergraduates filled out a survey that included the ZTPI and measures that assessed personality characteristics, and quality of parent, peer, and adult relationships. Results showed that deviation from BTP was positively associated with romantic anxiety (r = .41, p < .001), romantic avoidance (r = .33, p < .001), and neuroticism (r = .49, p < .001) but negatively associated with self-esteem (r = - .50, p < .001) and security of the mother (r = -. 38, p < .001), father (r = -. 37, p < .001) and peer (r = -. 27, p < .001) attachment. When personality and attachment measures were employed in a regression analysis, father attachment, romantic anxiety, self-esteem, and neuroticism were found to be significant predictors of the deviation from BTP scores (adjusted R-2 = .39, f(2) = .75). Finally, the inter-correlations of the ZTPI dimensions and their correlations with the personality and attachment measures provided additional support for the validity and reliability of the Turkish version of the ZTPI. These findings imply that positive perceptions of self and of interpersonal relationships are crucial in the development of BTP.Öğe Personality and work-family spillover: Testing the moderating role of segmentation supplies(John Wiley & Sons Ltd, 2023) Argin, Sema; Akirmak, Umit[Abstract Not Available]Öğe A Study on the Reliability and Validity of the Turkish Free Association Norms(Turkish Psychologists Assoc, 2018) Akirmak, Umit; Orhon, Mehmet AltanPre-existing semantic associations of words influence performance in various episodic tasks (Nelson, Dyrdal, & Good-mon, 2005). The free association task indexes strong associative relations among words. In turn, this makes it possible to map associative structure of the words in semantic memory. Although Tekcan and Goz (2005) collected free association norms of Turkish words in an earlier study, the reliability and validity of their findings have not been empirically tested with a specific study. The goal of the present study was to determine the reliability and validity of the existing free association norms. In Study 1, 100 words were randomly selected from the existing normative database and were normed again by using the standard free association method as well as an online version of the same task in order to assess the reliability. The obtained findings were compared in regard to associative strength, associative set size, and heterogeneity values. The results indicated that the existing norms have high reliability. Study 2 assessed the predictive validity of the existing norms in an extra-list cued recall experiment. The cue-to-target strength and cue set size were manipulated in order to examine their effects on correct recall. In line with the previous findings, high cue-to-target strength led to higher recall rates compared to low cue-to-target strength; however, the effects of cue set size were not in the expected direction. The present findings imply that the existing free association norms have high reliability and validity overall, but there is a crucial need to overcome the shortcomings of the Turkish free association norms by norming additional words.Öğe The validity and reliability of the Zimbardo time perspective inventory in a Turkish sample(Springer, 2021) Akirmak, UmitThe present study evaluated the validity and reliability of the Zimbardo Time Perspective Inventory (ZTPI; Zimbardo & Boyd, Journal of Personality and Social Psychology, 77(6), 1271-1288, 1999) in a Turkish sample. A Turkish version of the ZTPI was administered to participants in Study 1 (n = 554) while another group of participants filled out the ZTPI as well as measures of personality, locus of control, self-esteem, and self-efficacy in Study 2 (n = 234). Test-retest reliability of the ZTPI scores was assessed on the Study 2's sample (n = 88) over a 2-week period. The Turkish ZTPI demonstrated adequate internal consistency and test-retest reliability with minor exceptions. Confirmatory factor analyses (CFA) supported the five-factor structure of the original scale suggesting that the ZTPI has cross-cultural validity. However, similar to prior adaptation studies, the model fit values ranged from poor to good, suggesting a need for additional research on the psychometric properties of the ZTPI. Finally, the applicability of the deviation from balanced perspective scores was examined and unique relationships were demonstrated: balanced time perspective was associated with high conscientiousness and internal locus of control. Findings are discussed in relation to the time perspective theory, and the recommendations to improve the ZTPI's structural validity are provided.Öğe Time perspective and health: An evidence from a Turkish sample(John Wiley & Sons Ltd, 2023) Akirmak, Umit[Abstract Not Available]Öğe Turkish adaptation of the implicit leadership scale(John Wiley & Sons Ltd, 2023) Erbil, Esra; Akirmak, Umit[Abstract Not Available]
