The development and psychometric properties of the Turkish death anxiety scale (TDAS)

Sarikaya, Yusuf
Baloğlu, Mustafa
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 Agony of Death), which explained over 67% of the total variability. Confirmatory factor analyses indicated acceptable fit. Significant correlations were found between the scale and death anxiety, state anxiety, trait anxiety, depression, and hopelessness in the student sample. In the adult sample, death anxiety significantly correlated with trait anxiety. Reliability coefficients were also found acceptable. The authors conclude that the TDAS is a promising instrument in assessing the death anxiety levels in Turkey.


An investigation of the validity and reliability of the adapted mathematics anxiety rating scale-short version (MARS-SV) among Turkish students
Baloğlu, Mustafa (Springer Science and Business Media LLC, 2010-12-01)
This study adapted the Mathematics Anxiety Rating Scale-Short Version (MARS-SV) into Turkish and investigated the validity and reliability of the adapted instrument. Twenty-five bilingual experts agreed on the language validity, and 49 Turkish language experts agreed on the conformity and understandability of the scale's items. Thirty-two subject matter experts' responses provided evidence for content validity. Finally, 475 college students (51.58% men) responded to the adapted scale. Based on the existing ...
Interplay of motivational and cognitive strategies in predicting self-efficacy and anxiety
Aydin, Yesim Capa; Kondakçı, Esen; Demirdogen, Betul (Informa UK Limited, 2011-01-01)
The purpose of the present study was to test a model explaining self-efficacy and anxiety by the interrelationships with task value, cognitive strategies (rehearsal, elaboration and organisation) and metacognitive self-regulation in the domain of chemistry. Data were collected from 518 college students in Turkey. Findings of structural equation modelling indicated that chemistry self-efficacy and anxiety were predicted as a function of task value, cognitive strategies and metacognitive self-regulation, supp...
The adaptation and preliminary psychometric properties of the Derived Chemistry Anxiety Rating Scale
Senocak, Erdal; Baloğlu, Mustafa (2014-01-01)
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 psychometr...
The mediating role of metacognition on the relationship among depression/anxiety/negative impact of life experiences and smoking dependence
Yarış, Seval; Bozo Özen, Özlem; Department of Psychology (2010)
The aim of the present study was to investigate the role of metacognition as a mediator of the relationship between smoking dependence and depression/anxiety/ negative impact of life experiences. A sample of 202 adult smokers completed the following questionnaires: Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Life Experiences Survey (LES), Meta-Cognitions Questionnaire-30 (MCQ-30), and Fagerström Test of Nicotine Dependence (FTND). The path analyses were used to test a mediation model in w...
The Reliability and Validity of the Lifespan Sibling Relationship Scale in a Turkish Emerging Adult Sample
Cilali, Bengu; Erdur Baker, Özgür; Bugay, Asli (Central Library of the Slovak Academy of Sciences, 2019-01-01)
The present study examines the reliability and validity of the Turkish version of the Lifespan Sibling Relationship Scale (LSRS; Riggio, 2000). A total of 578 (336 female, 242 male) Turkish emerging adults participated in this study. A Confirmatory Factor Analysis (CFA) was used to test construct validity for the original six-factor model of the scale with 48 items. Results of the CFA indicated a good model fit. Furthermore, the second-order CFA result showed that the scale can be scored for both the subdim...
