    The reliability and validity of the turkish version of the world health organizat on quality of life instrument-older adults module (WHOQOL-Old)
    (Turkish Association of Nervous and Mental Health, 2010) Eser S.; Saatli G.; Eser E.; Baydur H.; Fidaner C.
    Purpose: To determine the psychometric properties of the Turkish version of the World Health Organization Quality of Life Instrument-Older Adults Module (WHOQOL-Old). Methods: The Turkish version of the WHOQOL-OLD was administered to 527 older (> 65 years) adults living in urban, suburban, and rural areas of Manisa Province, Turkey. The WHOQOL-OLD module consists of 24 items assigned to 6 facets (sen sory abilities, autonomy, past, present and future activities, so cial participation, death and dying, and intimacy) and is a supplementary module of WHOQOL-BREF. The WHOQOL-BREF and GDS-30 were also administered to the participants. A confirmatory approach was used during reliability and validity analysis. SPSS v.10.0 and LISREL v.8.54 were used for analysis. Results: Mean age of the participants was 71.06 ± 5.20 years and the overall WHOQOL-OLD score was 56.02 ± 11.86. In all, 54.5% of the participants were female and 60.5% reported to be in poor health. Both ceiling and floor effects of the WHOQOL-OLD were satisfactory (< 0.05%). Alpha values for the facets and overall scale (range: 0.68-0.88) (> 0.70), and item total correlations and overall scale success were satisfactory. As a measure of the construct validity of the scale, confirmatory factor analysis showed very high CFI values (range: 0.936-0.999) for each of the domains. Convergence of WHOQOL-OLD facet scores on WHOQOL-BREF domains and WHOQOL-OLD were very fine in general. Conclusions: The psychometric properties of the Turkish version of the WHOQOL-OLD were acceptable, indicating that the scale is reliable and valid for use with older Turkish adults (> 65 years).

    Comparison of generic and lung cancer-specific quality of life instruments for predictive ability of survival in patients with advanced lung cancer
    (SpringerOpen, 2016) Eser S.; Göksel T.; Erbaycu A.E.; Baydur H.; Başarık B.; Yanık A.Ö.; Gürsul K.K.; Çelik P.; Ediz E.Ç.; Hatipoğlu O.; Yayla B.A.; Başer S.; Eser E.
    Background: Our purpose is to examine the relationship of Health related quality of life measured by EORTC QLQc30, QLQ-LC13; FACT-L, LCSS, Eq5D) with survival in advanced lung cancer patients. A total of 299 Lung Cancer (LC) patients were, included in this national multicenter Project entitled of “the LC Quality of Life Project (AKAYAK). Baseline scores were analyzed by using Cox’s proportional hazard regression to identify factors that influenced survival. Univariate and multivariate models were run for each of the scales included in the study. Results: Mean and median survival were 12.5 and 8.0 months respectively. Clinical stage (as TNM), comorbidity; symptom scales of fatigue, insomnia, appetit loss and constipation were associated with survival after adjustment for age and sex. Global, physical and role functioning scales of QLQc30; physical and functional scales of LCS and TOI of the FACT-L was also associated with survival. Mobility and Usual activities dimensions of the Eq5D; Physical functioning and the constipation symptom scale of the QLQ-c30; and LCS and TOI scores of the FACT-L remained statistically significant after adjustment. LC13 and LCSS scales were not predictors of survival. Conclusions: HRQOL serves as an additional predictive factor for survival that supplements traditional clinical factors. Besides the strong predictive ability of ECOG on survival, FACT-L and the Eq5D are the most promising HRQOL instruments for this purpose. © 2016, The Author(s).

    Psychometric properties of the Turkish version of the World Health Organization quality of life instrument for people with intellectual and physical disabilities (WHOQOL-DIS-TR)
    (Turkish Association of Nervous and Mental Health, 2018) Eser E.; Aydemir O.; Özyurt B.C.; Akar A.; Deveci S.; Eser S.; Ayik C.
    Objective: The aim of this study was to present the validity and reliability of the Turkish version of the add-on module for the WHOQOL measure of quality of life. The module was used on adults with physical or intellectual disabilities known as the WHOQOL-DIS. Methods: Data were collected from 150 Intellectual Disabled (ID) and 157 Physically Disabled (PD) persons in the Turkish (Izmir) Participating Center of the Global WHOQOL-DIS Project. The WHOQOL-DIS module consisted of 12 disability specific items along with 26 generic items of WHOQOl-Bref. The proposed factorial structure (3 factors) of WHOQOL-DIS global study was used in the psychometric analyses of the Turkish versions of WHOQOL-DIS. Reliability analyses and construct validity were tested via CFA analyses, while convergent and discriminant validity analyses was assessed in relation to Satisfaction with Life Scale (SWLS) and WHO Disability Assessment Schedule-II (WHODAS-II), respectively. Results: Cronbach alpha values of the WHOQOL-DIS factors were as follows for ID and PD samples respectively: Factor 1 (Discrimination and support) = 0.54 and 0.64; Factor 2 (Independence) = 0.78 and 0.79; Factor 3 (Community participation) = 0.88 and 0.83. CFI and RMSEA values were 0.98 and 0.065 for ID sample and 0.98 ve 0.064 for PD sample, respectively. Convergent-discriminant validities were satisfactory for all factors in the PD group (r = 0.27 - 0.62) whereas, Factor 1 was not found discriminative in the ID group (r = 0.09 -0.10) Conclusion: Psychometric properties provided satisfactory evidence of reliability and validity of the PD and ID Turkish versions of WHOQOL-DIS (WHOQOL-DIS-TR-D and WHOQOL-DIS-TR-ID). Nevertheless, the results of Factor 1 (discrimination and support) in ID version should be interpreted with caution. WHOQOL-DIS should be applied to the disabled persons jontly with its core (generic) domains (WHOQOL-BREF) and the disablity module (38 item version) for the sake of holistic evaluation of QOL. We recommend further studies to explore the sensitivity of the WHOQOL-DIS on various variables in the field. © 2018, Turkish Association of Nervous and Mental Health.

    Psychometric characteristics of turkish version of parental attitudes towards childhood vaccines (PACV) scale; [Ebeveynlerin çocukluk aşilarina yönelik tutumlari (PACV) ölçeğinin türkçe sürümünün psikometrik özellikleri]
    (Galenos Publishing House, 2020) Çevik C.; Güneş S.; Eser S.; Eser E.
    INTRODUCTION: Vaccination hesitation is an important public health problem that has increased in recent years. The aim of this study was to determine the psychometric properties of the Turkish version of the Parenting Attitudes towards Childhood Vaccines Scale (PACV). MATERIALS and METHODS: This methodological study was conducted between January-May 2019 with parents of 0-59 months old children (n = 211) who applied to Balıkesir University Health Application and Research Hospital Children's Polyclinic. PACV scale consists of 15 items in four dimensions: behavior, attitude, safety and effectiveness dimensions. Internal consistency (using Cronbach's alpha value) was used in reliability analyzes, structural validity (known groups and confirmatory factor analysis) and discriminant validity were used in validity analyzes. In the confirmatory factor analysis (CFA), the Comparative Compliance Index (BSI-CFI) and RMSEA were used. In the analysis, SS SPSS version 21.0 for Windows program and Lisrel 8.54 statistical package programs were used. RESULTS: 68.2% of the parents were women, 85.3% had sufficient income perception and 68.7% had only one child. The mean age was 30.84±5.15 for parents and 3.24±1.63 for children. Floor and ceiling effects of the scale are within the desired limits. Cronbach's alpha value of the scale was 0.676. Test-retest results are good (ICC: 0.93, p: 0.001). In the explanatory factor analysis, KMO was 0.77 and the total explained variance was 57.41%. In the Confirmatory Factor Analysis, compliance indicators are good (X2 / sd: 1.87, RMSEA: 0.0652, CFI: 0.949, NFI: 0.90). The scale was found to be discriminant according to the validity of known groups. CONCLUSIONS: The PACV scale is a valid and reliable scale adapted to the Turkish population. Parents' Attitudes towards Childhood Vaccines Scale is sufficient and satisfactory in terms of distribution, measurement ability, internal consistency and model fit. Total correlation after overlap correction was found below 30 in questions 7 and 14 and the results must be interpreted with caution. © 2020, Galenos Yayincilik,. All rights reserved.

    NORMATIVE AND PSYCHOMETRIC PROPERTIES OF THE WHOQOL OLDER ADULTS MODULE (WHOQOL-OLD) IN THE NATIONAL REPOSITORY
    (Geriatrics Society, 2022) Eser E.; Bilgin Şahin B.; Eser S.
    Introduction: The main objectives of this study were to present population norms and the construct validity of the WHOQOL-OLD using classical and modern (Rasch) psychometric analyses. Methods: This study was conducted on the pooled data of 29 studies, 16 of which were representative of the population (n=6951). The psychometric properties of the WHOQOL-OLD were evaluated with classical (confirmatory factor analysis and multivariate regression model) and probabilistic test theory (Rasch and DIF) analyses. Results: The mean age of the Turkish WHOQOL-OLD data pool was 73.2±6.8. The mean overall scale score was 81.27±13.57 and the range of the mean dimension scores was between 12.34 (social participation) and 14.59 (intimacy). The elderly (advanced age) and women are more sensitive to the decrease in quality-of-life (QoL) scores. Both Cronbach’s alpha values and item analyses indicated good internal consistency for all dimensions. Exploratory factor analyses (EFA) generated five factors instead of a six-factor original scale structure. “Past, present, and future activities” and “social participation” were combined in a single dimension in the EFA. Confirmatory factor analyses resulted in acceptable goodness of fit indices, such as Confirmation Fit Index (CFI)=0.951 and Root Mean Square Error of Approximation (RMSEA)=0.055. Turkish elders perceive the death and dying dimension as culturally closer to the culture of developing countries than developed Western cultures. Conclusion: Turkish older adults’ QoL scores were more or less like those of other older adults in developing countries. This study’s results confirm that the acceptable psychometric properties of the WHOQOL-OLD-TR with some items (items 9 and 20) need to be worked on further. © 2022, Geriatrics Society.

    Psychological Determinants of Turkish Farmers’ Health and Safety Behaviors: An Application of the Extended Theory of Planned Behavior
    (MDPI, 2023) Baydur H.; Eser E.; Sen Gundogan N.E.; Ayhan E.; Eser S.; Dede B.; Hazneci E.; Öztekin Y.B.; Ekuklu G.; Cevizci S.; Van den Broucke S.
    Background: Structural and behavioral factors are among the causes of occupational accidents in agriculture. The SACURIMA Cost network developed a questionnaire to measure the determinants of farmers’ safety behavior based on the extended theory of planned behavior (TPB). Extended TPB adds subjective norms, subjective control, physical barriers and safety culture to TPB. Objective: The aim of this study is to test the psychometric properties of the “Farmers Safety Behaviors questionnaire” developed by the SACURIMA Cost network. Methods: A Turkish version of the questionnaire was applied to 305 farmers producing six different agricultural products in Turkey. The tool consists of 64 items measuring the determinants of four risk-related behaviors (fall prevention, machine handling, chemical-pesticide use, and animal handling) in a single extended TPB model. Results: The alpha values for the six dimensions ranged from 0.69 to 0.89. The confirmatory factor analysis results for all dimensions were at acceptable levels (CFI range = 0.93–0.99; RMSEA range = 0.03–0.09). Four path models were used to test the behaviors and their predictors, and the results were found to be predictive. The criterion and known groups’ validity analyses results were sufficient. Conclusion: The “Farmers Safety Behaviors Questionnaire” is a valid and reliable tool to measure the determinants of occupational safety behaviors in Turkish farmers. © 2023 by the authors.

    Phenomenon: Physician immigration from other countries is increasing as developed countries continue to be desirable destinations for physicians; however, the determinants of Turkish physicians’ migration decisions are still unclear. Despite its wide coverage in the media and among physicians in Türkiye, and being the subject of much debate, there is insufficient data to justify this attention. With this study, we aimed to investigate the tendency of senior medical students in Türkiye to pursue their professional careers abroad and its related factors. Approach: This cross-sectional study involved 9881 senior medical students from 39 different medical schools in Türkiye in 2022. Besides participants’ migration decision, we evaluated the push and pull factors related to working, social environment and lifestyle in Türkiye and abroad, medical school education inadequacy, and personal insufficiencies, as well as the socioeconomic variables that may affect the decision to migrate abroad. The analyses were carried out with a participation rate of at least 50%. Findings: Of the medical students, 70.7% had emigration intentions. Approximately 60% of those want to stay abroad permanently, and 61.5% of them took initiatives such as learning a foreign language abroad (54.5%) and taking relevant exams (18.9%). Those who wanted to work in the field of Research & Development were 1.37 (95% CI: 1.22–1.54) times more likely to emigrate. The push factor that was related to emigration intention was the “working conditions in the country” (OR: 1.89, 95% CI: 1.56–2.28) whereas the “social environment/lifestyle abroad” was the mere pull factor for the tendency of emigration (OR: 1.73, 95% CI: 1.45–2.06). In addition, the quality problem in medical schools also had a significant impact on students’ decisions (OR: 2.20, 95% CI: 1.83–2.65). Insights: Although the percentage of those who want to emigrate “definitely” was at the same level as in the other developing countries, the tendency to migrate “permanently” was higher in Türkiye. Improving working conditions in the country and increasing the quality of medical faculties seem vital in preventing the migration of physicians. © 2023 Taylor & Francis Group, LLC.
