Sleep quality, quality of life, fatigue, and mental health in COVID-19 post-pandemic Türkiye: A cross-sectional study
(Frontiers, 2024) Bener, Abdulbari; Morgül, Ebru; Tokaç, Mahmut; Ventriglio, Antonio; Jordan, Timothy R.; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji Bölümü
Aim: This study explores the predictors and associated risk factors of sleep quality, quality of life, fatigue, and mental health among the Turkish population during the COVID-19 post-pandemic period. Materials and methods: A cross-sectional survey using multi-stage, stratified random sampling was employed. In total, 3,200 persons were approached. Of these, 2,624 (82%) completed the questionnaire package consisting of socio-demographic information, Pittsburgh Sleep Quality Index (PSQI), the WHO Quality of Life Brief Version (WHOQOL-BREF), Fatigue Assessment Scale (FAS), Patients Health Questionnaire (PHQ-15), GAD-7 anxiety scale, and the 21-item Depression, Anxiety, Stress Scale (DASS-21). Results: Significant differences between genders were found regarding socio-demographic characteristics (p < 0.01). Using PHQ-15 for depressive disorders, significant differences were found between normal and high severity scores (≥ 10), regarding age group (p < 0.001), gender (p = 0.049), educational level (p < 0.001), occupational status (p = 0.019), cigarette smoking (p = 0.002), waterpipe-narghile smoking (p = 0.039), and co-morbidity (p = 0.003). The WHOQOL-BREF indicated strong correlations between public health, physical health, psychological status, social relationships, environmental conditions, and sleep disorders (p < 0.01). Furthermore, comparisons of the prevalence of mental health symptoms and sleeping with PHQ-15 scores ≥ 10 (p = 0.039), fatigue (p = 0.012), depression (p = 0.009), anxiety (p = 0.032), stress (p = 0.045), and GAD-7 (p < 0.001), were significantly higher among the mental health condition according to sleeping disorder status. Multiple regression analysis revealed that DASS21 stress (p < 0.001), DASS21 depression (p < 0.001), DASS21 anxiety (p = 0.002), physical health (WHOQOL-BREF) (p = 0.007), patient health depression-PHQ-15 (p = 0.011), psychological health (WHOQOL-BREF) (p = 0.012), fatigue (p = 0.017), and environmental factors (WHOQOL-BREF) (p = 0.041) were the main predictor risk factors associated with sleep when adjusted for gender and age. Conclusion: The current study has shown that sleep quality was associated with the mental health symptoms of depression, anxiety, stress, and fatigue. In addition, insufficient sleep duration and unsatisfactory sleep quality seemed to affect physical and mental health functioning.
Why do young adults in the United States have such low rates of organ donation registration?
(MDPI AG, 2022) Wotring, Amy J.; Jordan, Timothy R.; Saltzman, Barbara; Glassman, Tavis; Holloway, Jennifer; Khubchandani, Jagdish; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji Bölümü
The demand for transplantable organs has outpaced the supply. Thus, 20 Americans die every day while waiting for an organ. Although most adults support organ donation, 42% are not registered. The rate is even lower among young adults who are not enrolled in/never graduated from college. The aim of this study was to use the Integrated Behavior Model (IBM) to identify factors that predicted organ donation registration among a racially diverse sample of non-student young adults. The study was observational and cross-sectional. Proportional allocation was used to identify a racially diverse sample of 550 non-student, young adults from ten states in the U.S. with the lowest registration rates. A valid and reliable survey was designed, pilot-tested, and administered. A total of 407 young adults completed the survey (74%). Only 19% were registered donors. Caucasians were more likely to be registered donors than racial minorities, ? 2 (3, N = 407) = 15.19, p = 0.002. Those with more positive direct attitudes toward registration were 1.5 times more likely to be registered than those who had negative direct attitudes. Among non-registrants, indirect descriptive norm and direct attitude were statistically significant predictors of behavioral intention. Moreover, those who knew someone who donated an organ and knew someone who needed a transplant were nearly three times more likely to intend to register in the next year. The IBM proved useful in elucidating factors that predicted intention to register among non-student young adults. The IBM should be used by those who desire to increase registration rates.
Multicenter registry and test bed for extended outpatient hemodynamic monitoring: The hemodynamic frontiers in heart failure (HF2) initiative
(Frontiers, 2023) Heywood, J. Thomas; Munshi, Kartik; Jordan, Timothy R.; Muse, Evan; Fudim, Marat; Sauer, Andrew J.; McDermott, Margaret; Shah, Hirak; Bhimaraj, Arvind; Khedraki, Rola; Robinson, Monique R.; McCann, Patrick; Volz, Elizabeth; Guha, Ashrith; Jonsson, Orvar; Bhatt, Kunjan A.; Bennett, Mosi K.; Benjamin, Terrie Ann; Guglin, Maya; Abraham, Jacob; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji Bölümü
Background: Hemodynamic Frontiers in Heart Failure (HF2) is a multicenter academic research consortium comprised of 14 US institutions with mature remote monitoring programs for ambulatory patients with heart failure (HF). The consortium developed a retrospective and prospective registry of patients implanted with a wireless pulmonary artery pressure (PAP) sensor. Goals/aims: HF2 registry collects demographic, clinical, laboratory, echocardiographic (ECHO), and hemodynamic data from patients with PAP sensors. The aims of HF2 are to advance understanding of HF and to accelerate development of novel diagnostic and therapeutic innovations. Methods: HF2 includes adult patients implanted with a PAP sensor as per FDA indications (New York Heart Association (NYHA) Class III HF functional class with a prior hospitalization, or patients with NYHA Class II or brain natriuretic peptide (BNP) elevation without hospitalization) at a HF2 member site between 1/1/19 to present. HF2 registry is maintained at University of Kansas Medical Center (KUMC). The registry was approved by the institutional review board (IRB) at all participating institutions with required data use agreements. Institutions report data into the electronic registry database using REDCap, housed at KUMC. Results: This initial data set includes 254 patients implanted from the start of 2019 until May 2023. At time of device implant, the cohort average age is 73 years old, 59.8% are male, 72% have NYHA Class III HF, 40% have left ventricular ejection fraction (LVEF) < 40%, 35% have LVEF > 50%, mean BNP is 560 pg/ml, mean N-Terminal pro-BNP (NTproBNP) is 5,490 pg/ml, mean creatinine is 1.65 mg/dl. Average baseline hemodynamics at device implant are right atrial pressure (RAP) of 11 mmHg, pulmonary artery systolic pressure (PASP) of 47 mmHg, pulmonary artery diastolic pressure (PADP) 21 mmHg, mean pulmonary artery pressure (mPAP) of 20 mmHg, pulmonary capillary wedge pressure (PCWP) of 19 mmHg, cardiac output (CO) of 5.3 L/min, and cardiac index (CI) of 2.5 L/min/m2. Conclusion: A real-world registry of patients implanted with a PAP sensor enables long-term evaluation of hemodynamic and clinic outcomes in highly-phenotyped ambulatory HF patients, and creates a unique opportunity to validate and test novel diagnostic and therapeutic approaches to HF.
Further investigation of the effects of wearing the hijab: Perception of female facial attractiveness by Emirati Muslim men living in their native Muslim country
(Plos One, 2020) Jordan, Timothy R.; Jordan, Timothy R.; Yekani, Hajar Aman Key; Sheen, Mercedes; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji Bölümü; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji Bölümü
The hijab is central to the lives of Muslim women across the world but little is known about the actual effects exerted by this garment on perceptions of the wearer. Indeed, while previous research has suggested that wearing the hijab may affect the physical attractiveness of women, the actual effect of wearing the hijab on perceptions of female facial attractiveness by Muslim men in a Muslim country is largely unknown. Accordingly, this study investigated the effects of the hijab on female facial attractiveness perceived by practising Muslim men living in their native Muslim country (the United Arab Emirates). Participants were presented with frontal-head images of women shown in three conditions: in the fully covered condition, heads were completely covered by the hijab except for the face; in the partially covered condition, heads were completely covered by the hijab except for the face and areas around the forehead and each side of the face and head; in the uncovered condition, heads had no covering at all. The findings revealed that faces where heads were uncovered or partially covered were rated as equally attractive, and both were rated as substantially more attractive than faces where heads were fully covered. Thus, while wearing the hijab can suppress female facial attractiveness to men, these findings suggest that not all hijab wearing has this effect, and female facial attractiveness for practising Muslim men living in their native Muslim country may not be reduced simply by wearing this garment. Indeed, from the findings we report, slight changes to the positioning of the hijab (the partially covered condition) produce perceptions of facial attractiveness that are no lower than when no hijab is worn, and this may have important implications for wearing the hijab in Muslim societies. Finally, we argue that the pattern of effects we observed is not explained by anti-Islamic feeling or cultural endogamy, and that a major contributory factor is that being fully covered by the hijab occludes external features, especially the hair and lateral parts of the head and face, which, when normally visible, provide a substantial perceptual contribution to human facial attractiveness.
The good, the bad and the hijab: A study of implicit associations made by practicing Muslims in their native Muslim country
(SAGE, 2022) Jordan, Timothy R.; Jordan, Timothy R.; Sheen, Mercedes; Yekani, Hajar Aman Key; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji Bölümü; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji Bölümü
Recent research indicates that wearing the hijab reduces the attractiveness of female faces perceived by practicing Muslim men and women in their native Muslim country (the United Arab Emirates). The purpose of the current research was to develop this finding to investigate whether other aspects of person perception are also affected when women wear the hijab in this Muslim country. Of particular relevance is that changes in physical attractiveness often affect the personal qualities assigned to individuals. Accordingly, we sought to determine whether such effects occur when the physical attractiveness of women is altered by wearing the hijab. To do this, we used an Implicit Association Test (IAT) to investigate how native Muslim participants in the UAE associated pleasant and unpleasant connotations with images of women either wearing the hijab or with their heads uncovered. As in previous research with native Muslim participants, female faces were again perceived as significantly less attractive when the hijab was worn. However, the accompanying IAT findings showed that these less attractive hijab-wearing images were associated more with pleasant connotations than were the matched uncovered images. These findings provide fresh insight into the effects of the hijab on perceptions of Muslim women in a Muslim country and provide support for the view that cultural clothing can influence person perception beyond physical attractiveness alone.
COVID-19 pandemic and psychological fatigue in Turkey
(SAGE, 2020) Morgül, Ebru; Bener, Abdulbari; Atak, Muhammed; Akyel, Salih; Aktaş, Selman; Bhugra, Dinesh; Ventriglio, Antonio; Jordan, Timothy R.; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji Bölümü
Aim: The aim of this study was to investigate the association between the COVID-19 pandemic and psychological fatigue as a mental health issue among the population of Istanbul, Turkey. Participants and methods: This is a cross-sectional study conducted in Istanbul, Turkey, between March and June 2020, where a total of 4,700 persons were approached and 3,672 (78%) of participants (64.4% males and 35.6% females) completed the Knowledge Attitude Practices (KAP) and Fatigue Assessment Scale (FAS) questionnaires. Results: In this study, 64.1% of participants were categorized as psychologically fatigued and 35.9% as normal. There was a significant difference between fatigued and normal participants with respect to age, educational level, occupational status, place of residence and number of family members (p < .001). Other differences related to knowledge of COVID-19 were symptoms, treatment, ways of spreading (p < .001), prevention by avoiding crowded places (p = .008) and isolation (p = .002). For attitudinal items, normal participants generally showed more positive attitudes than the fatigued in believing that COVID-19 will finally be controlled, satisfaction with preventive measures taken by the authorities, reporting suspected cases with symptoms and trusting that Turkey can overcome the COVID-19 pandemic (p < .001). Multivariate stepwise regression analysis indicated that level of education, avoiding going to crowded places, eye, nose and mouth organs are sensitive organs to the virus, keeping physical distance due to epidemic affect by COVID-19 virus, isolation and treatment of people reduce the spread of COVID-19 virus and 14-days period of time, COVID-19 is mainly transmitted through contact with the respiratory droplets of an infected person, occupational status, health education programme needed and antibody treatment variables were significantly associated with fatigue after adjusting for age, gender and income variables. Conclusion: The current study provides valuable information for policymakers and mental health professionals worldwide regarding associations between the mental health of individuals and the ongoing outbreak, COVİD-19.
Revealing a word superiority effect using a unique variant of the Latin alphabet: The evidence from Turkish
(Frontiers, 2024) Jordan, Timothy R.; Kalan, Aleynanur; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji Bölümü
When visual stimuli are presented briefly, words are perceived better than nonwords. It is widely accepted that this word superiority effect reflects the efficiency with which words are perceived. However, most of what is known about the effect comes from languages (like English) using the basic Latin alphabet and little is known about whether languages using an alphabetic variant with very different properties can also produce word superiority. Here we report an experiment in which words and nonwords were presented briefly in Turkish, which uses a unique variant of the Latin alphabet containing 29 separate letters, 12 of which are close visual replications of other letters. Despite the potential for visual confusability and perceptual uncertainty, the findings revealed a clear advantage for words over nonwords, indicating that word superiority observed previously for the Latin alphabet can also be observed with the very different variant of this alphabet used for Turkish. Implications of these findings for processes involved in visual word perception are discussed.
COVID-19 vaccine hesitancy among university students in Lebanon
(Research Square, 2021) Hamdan, Mima Bou; Singh, Shipra; Polavarapu, Mounika; Melhem, Nada; Jordan, Timothy R.; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji Bölümü
Background: Lebanon has one of the lowest reported COVID-19 vaccine acceptance rates (21%). Little is known about the decision-making process of college students in Lebanon regarding obtaining a COVID-19 vaccination. Therefore, the aim of this study was to identify factors that predicted the behavioral intentions of students enrolled at the American University of Beirut (AUB), Lebanon to obtain a COVID-19 vaccine. Methods: The study was a randomized, non-experimental, and cross-sectional study of undergraduate and graduate students. A valid and reliable survey was developed. A total of 3,805 students were randomly selected to participate from all academic units. A total of 800 students responded (21% return rate). Results: We generated three groups based on students’ intentions to be vaccinated: 1) vaccine accepting (those who are willing to take or already took the vaccine); 2) vaccine hesitant (those who are hesitant to take the vaccine); and 3) vaccine resistant (those who decided not to take the vaccine). The majority were Lebanese (85%), undergraduate students (75%), females (57%) with a mean age of 21?±?0.14 years. Overall, students were vaccine accepting. Specifically, they were vaccine accepting (87%), vaccine hesitant (10%), and vaccine resistant (3%). Vaccine hesitancy was significantly associated with nationality, residency status and university rank (p value?
Gendered perceptions of odd and even Numbers: An implicit association study from Arabic culture
(Frontiers Media, 2021) Jordan, Timothy R.; Yekani, Hajar Aman Key; Sheen, Mercedes; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji Bölümü
Previous studies conducted in the United States indicate that people associate numbers with gender, such that odd numbers are more likely to be considered male and even numbers considered female. It has been argued that this number gendering phenomenon is acquired through social learning and conditioning, and that male-odd/female-even associations reflect a general, cross-cultural human consensus on gender roles relating to agency and communion. However, the incidence and pattern of number gendering in cultures outside the United States remains to be established. Against this background, the purpose of this study was to determine whether people from a culture and country very different from the United States (specifically, native Arabic citizens living in the Arabic culture of the United Arab Emirates) also associate numbers with gender, and, if they do, whether the pattern of these associations is the male-odd/female-even associations previously observed. To investigate this issue, we adopted the Implicit Association Test used frequently in previous research, where associations between numbers (odd and even) and gender (male and female faces) were examined using male and female Arabic participants native to, and resident in, the United Arab Emirates. The findings indicated that the association of numbers with gender does occur in Arabic culture. But while Arabic females associated odd numbers with male faces and even numbers with female faces (the pattern of previous findings in the United States), Arabic males showed the reversed pattern of gender associations, associating even numbers with male faces and odd numbers with female faces. These findings support the view that number gendering is indeed a cross-cultural phenomenon and show that the phenomenon occurs across very different countries and cultures. But the findings also suggest that the pattern with which numbers are associated with gender is not universal and, instead, reflects culture-specific views on gender roles which may change across cultures and gender. Further implications for understanding the association of numbers with gender across human societies are discussed.
Investigating associations between cognitive empathy, affective empathy and anxiety in adolescents with autism spectrum disorder
(Taylor & Francis, 2023) Jordan, Timothy R.; Sönmez, Dilruba; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji Bölümü
Autism spectrum disorder (ASD) is strongly associated with socio-cognitive impairments that may result in vulnerability to other mental health conditions, particularly anxiety disorders. This study examined the relationship between anxiety disorders and two key socio-cognitive impairments (cognitive empathy, affective empathy) in 60 adolescents (aged 11–18?years) with and without ASD. Adolescents with ASD showed cognitive empathy was negatively associated with separation anxiety disorder, whereas positive associations between affective empathy and generalized anxiety disorder, and positive marginal associations between affective empathy, social phobia, total anxiety, and separation anxiety disorder were observed. These findings suggest that cognitive and affective empathy show different patterns of associations with anxiety-related issues in ASD, and these differences should be considered for interventions and treatment programs.
