The adaptation and preliminary psychometric properties of the Derived Chemistry Anxiety Rating Scale

Senocak, Erdal
Baloğlu, Mustafa
The current study adapted the Derived Chemistry Anxiety Rating Scale (DCARS) into Turkish and investigated the preliminary psychometric properties of the Turkish version. The Turkish DCARS is composed of three components, which are derived from 32 Likert-type items that purport to measure anxiety experienced in chemistry-related situations. In the adaptation procedure, English-Turkish conformity, Turkish language conformity and understandability, and back translation were used. In the preliminary psychometric investigation, structural validity, content validity, concurrent validity, internal consistency, and test-retest reliability were examined. Results show that item translations have high conformity with the original items and experts found the Turkish items understandable. Validity analyses confirmed the adapted scale's three-factor structure. In addition, concurrent validity was evidenced by significant positive correlation coefficients between the scale scores and the test anxiety and state-trait anxiety scores. Reliability analyses indicate high consistency among the scale items both at the total and sub-scale levels and that scale and subscale scores were stable over time. We conclude that the Turkish DCARS is a promising assessment instrument in measuring chemistry anxiety levels among Turkish college students.


The Adaptation of the Mathematics Anxiety Rating Scale-Elementary Form into Turkish, Language Validity, and Preliminary Psychometric Investigation
Baloğlu, Mustafa; Balgalmis, Esra (2010-12-01)
The purpose of the present study was to adapt the Mathematics Anxiety Rating Scale-Elementary Form (MARS-E, Suinn, 1988) into Turkish by first doing the translation of its items and then the preliminary psychometric investigation of the Turkish form. The study included four different samples: 30 bilingual language experts, 50 Turkish language experts, 50 mathematics subject matter experts, 21 school counselors, and 336 elementary school students. After each item was independently translated into Turkish by ...
The development and psychometric properties of the Turkish death anxiety scale (TDAS)
Sarikaya, Yusuf; Baloğlu, Mustafa (Informa UK Limited, 2016-01-01)
The purpose of the present study was to develop the Turkish Death Anxiety Scale (TDAS) and test its initial psychometric properties. Four independent samples participated in the study: 943 college students in item generation, 388 college students in validation, 171 college students in reliability investigation, and 338 adults in cross-validation. Principal component analysis with a varimax rotation revealed that 20 items of the scale contained three factors (i.e., Ambiguity of Death, Exposure to Death, and ...
The State and society relations in the early republican era : the state capacity and the hegemonic power of the Turkish State
Başaranlar, Burak; Ergut, Ferdan; Department of History (2013)
This study aims to examine the incapacity of Turkish state and the limitations of Kemalist regime to materialize the reforms. The study emphasizes that since the hegemonic and infrastructural power of the Turkish Republic was insufficient, the Kemalist regime partially failed to transform the society as it wished and could not legitimize the ideal behind the reforms because of the weak state structure. Firstly, theories about the state and society were touched upon. Three main theories which are liberal, Ma...
An Analysis of the Sources of COVID-19 Resilience and Vulnerability of Turkey in the First Wave of COVID-19
Özen, İlhan Can; Tuncay Alpanda, Berna (2022-05-01)
This paper aims to analyze the effects of the macro prevention efforts undertaken in Turkey at three different levels. We particularly focus on the effect of COVID-19 prevention arrangements on the health system resilience and resistance at a systemic level. Similarly, the social and health vulnerability of the regional populations to COVID-19 was measured, to encapsulate, in the first wave, to what extent these populations were able to be protected from the worst of the epidemic. We use regional and provin...
Examining the Reliability and Validity of the Turkish Version of the Trait Meta-Mood Scale
Bugay, Aslı; Aksöz, Idil; Erdur Baker, Özgür (2014-06-01)
The aim of the study was to investigate the reliability and validity of the Trait Meta-Mood Scale in a Turkish sample. Trait Meta-Mood Scale (TMMS), The Satisfaction with Life Scale (SWLS), Ruminative Response Scale (RRS), and Beck Depression Inventory (BDI)were administered to 387 (271 females and 113 males) university students with a mean age of 21.77 (SD = 1.65).In the present study, the Turkish model and the original model of TMMS were tested to examine which of the two model yields the better goodness ...
