    Hydrogen Tunneling Exhibiting Unexpectedly Small Primary Kinetic Isotope Effects
    (Wiley - VCH Verlag GmbH, 2024) Roque, Jose P. L.; Nunes, Claudio M.; Schreiner, Peter R.; FAUSTO, RUI
    Probing quantum mechanical tunneling (QMT) in chemical reactions is crucial to understanding and developing new transformations. Primary H/D kinetic isotopic effects (KIEs) beyond the semiclassical maximum values of 7–10 (room temperature) are commonly used to assess substantial QMT contributions in one-step hydrogen transfer reactions, because of the much greater QMT probability of protium vs. deuterium. Nevertheless, we report here the discovery of a reaction model occurring exclusively by H-atom QMT with residual primary H/D KIEs. 2-Hydroxyphenylnitrene, generated in N2 matrix, was found to isomerize to an imino-ketone via sequential (domino) QMT involving anti to syn OH-rotamerization (rate determining step) and [1,4]-H shift reactions. These sequential QMT transformations were also observed in the OD-deuterated sample, and unexpected primary H/D KIEs between 3 and 4 were measured at 3 to 20 K. Analogous residual primary H/D KIEs were found in the anti to syn OH-rotamerization QMT of 2-cyanophenol in a N2 matrix. Evidence strongly indicates that these intriguing isotope-insensitive QMT reactivities arise due to the solvation effects of the N2 matrix medium, putatively through coupling with the moving H/D tunneling particle. Should a similar scenario be extrapolated to conventional solution conditions, then QMT may have been overlooked in many chemical reactions.

    The Effect of Position on Feeding Performance in Infants With Cleft Lip and Palate: Quasiexperimental Study
    (Wiley, 2024) ERDOST, ŞERİFE KARTAL; Gözen, Duygu
    Purpose: This single-group, quasiexperimental study was conducted to determine the effect of feeding position on the physiological parameters and feeding performance of term-born infants with cleft lip and palate (CLP) in the preoperative period. Methods: The study sample consisted of 45 infants aged 0-6 months with CLP followed up preoperatively in our outpatient clinic between January 2021 and 2022. Infants who were being fed with a specialty bottle for babies with CLP and whose families consented to participate in the study were included. After 2 h of fasting, the infants were fed in the elevated supine (ESU) position for the first meal, then in the elevated side-lying (ESL) position for the second meal after another 2 h of fasting. The infants' heart rate and oxygen saturation values before, during, and after each feed and indicators of feeding performance were compared between the positions. Results: There was no significant difference between the positions in terms of heart rate and oxygen saturation before, during, or after feeding (p > .05). There was no statistically significant difference in measures of feeding performance according to the infants' feeding position (p > .05). Conclusion: According to the findings obtained in this study, infants with CLP showed no statistically significant differences in heart rate, oxygen saturation, or feeding performance when fed in the ESL and ESU positions. Practice Implications: However, despite the lack of statistical significance, both physiological values and feeding performance tended to be better when the infants were fed in the ESL position, nurses can practice ESL position according to the infant's opposite direction of the side of the cleft lip or palate.

    The Effects of Improvement in Upper Extremity Function on Gait and Balance in Children With Upper Extremity Affected
    (Elsevier Ireland Ltd., 2024) Leblebici, Gökçe; Tarakcı, Ela; Kısa, Eylül Pınar; AKALAN, NAZİF EKİN; Kasapçopur, Özgür
    Background: This study aimed to investigate the effects of functional improvement in the upper extremity on gait and balance in children with upper extremity affected. Research question: What are the effects of functional improvement in the upper extremity on gait and balance in children with upper extremity affected? Methods: Eighteen children with a diagnosis of rheumatologic diseases and 15 healthy children were evaluated with Shriners Hospital Upper Extremity Assessment, Jebsen-Taylor Hand Function Test, Abilhand Rheumatoid Arthritis Scale, 10-meter walk test and Childhood Health Assessment Questionnaire. For static balance assessment, the Biodex Balance was used. Ground reaction forces (peak forces (heel strike and push-off) and minimum force (loading response), single-limb support duration, Center-of-Force displacement and walking speed were evaluated with the Sensor Medica. Arm swing was evaluated with the Kinovea 2D motion analysis. Results: Before treatment, single-limb support duration and push-off force was higher and center-of-force displacement was lower on affected side compared to unaffected side in rheumatologic group. After the 6week rehabilitation program, upper extremity function, quality of life and functional gait score improved. Single-limb support duration decreased on affected side and increased on unaffected side. On affected side, pushoff force decreased. The arm swing parameters were similar before and after treatment. Significance: Improving upper extremity function can help with gait balance by decreasing the difference in walking and balance parameters between the affected and unaffected sides and providing for more symmetrical weight transfer.

    Recycling Ophthalmic Lens Wastewater in a Circular Economy Context: A Case Study with Microalgae Integration
    (MDPI, 2024) FAUSTO, RUI
    Water pollution poses a global threat to ecosystems and human health and is driven by the presence of various contaminants in wastewater, including nano- and microplastics. Despite the magnitude of this problem, the majority of global wastewater is released untreated into water bodies. To combat this issue, a multi-strategy approach is needed. This study explores a circular economy-based solution for treating emerging pollutants, particularly wastewater from ophthalmic spectacle lens production. Our approach integrates solid waste materials into polymeric and cement matrices while also utilising wastewater for microalgae cultivation. This innovative strategy focuses on biomass generation and economic valorisation. By adopting a circular economy model, we aim to transform environmental pollutants from wastewater into valuable organic products. A key component of our approach is the utilisation of microalgae, specifically Nannochloropsis sp., known for its high lipid content and resilience. This microalgae species serves as a promising biobased feedstock, supporting the production of innovative biobased products, such as biopolymers, for ophthalmic lens manufacturing. Our interdisciplinary approach combines microalgae technology, analytical chemistry, cement production, and polymer processing to develop a sustainable circular economy model that not only addresses environmental concerns, but also offers economic benefits. This study underscores the potential of harnessing high-value products from waste streams and underscores the importance of circular economy principles in tackling pollution and resource challenges.

    Lidocaine Inhibits Rat Prostate Cancer Cell Invasiveness and Voltage-Gated Sodium Channel Expression in Plasma Membrane
    (Springer, 2024) Rizaner, Nahit; Fraser, Scott P.; Gül, İlknur Bugan; Purut, Esma; Djamgoz, Mustafa B. A.; ALTUN, SEYHAN
    There is increasing evidence, mostly from breast cancer, that use of local anaesthetics during surgery can inhibit disease recurrence by suppressing the motility of the cancer cells dependent on inherent voltage-gated sodium channels (VGSCs). Here, the possibility that lidocaine could affect cellular behaviours associated with metastasis was tested using the Dunning cell model of rat prostate cancer. Mostly, the strongly metastatic (VGSC-expressing) Mat-LyLu cells were used under both normoxic and hypoxic conditions. The weakly metastatic AT-2 cells served for comparison in some experiments. Lidocaine (1-500 mu M) had no effect on cell viability or growth but suppressed Matrigel invasion dose dependently in both normoxia and hypoxia. Used as a control, tetrodotoxin produced similar effects. Exposure to hypoxia increased Nav1.7 mRNA expression but VGSC alpha protein level in plasma membrane was reduced. Lidocaine under both normoxia and hypoxia had no effect on Nav1.7 mRNA expression. VGSC alpha protein expression was suppressed by lidocaine under normoxia but no effect was seen in hypoxia. It is concluded that lidocaine can suppress prostate cancer invasiveness without effecting cellular growth or viability. Extended to the clinic, the results would suggest that use of lidocaine, and possibly other local anaesthetics, during surgery can suppress any tendency for post-operative progression of prostate cancer.

    The Immediate Effect of Hanging Exercise and Muscle Cylinder Exercise on the Angle of Trunk Rotation in Adolescent Idiopathic Scoliosis
    (MDPI, 2024) Akçay, Burçin; Çolak, Tuğba Kuru; APTİ, ADNAN; Çolak, İlker
    (1) Background: Semi-hanging and muscle cylinder exercises have been defined as scoliosis-specific corrective exercises. The aim of this study was to evaluate the immediate effect of muscle cylinder and semi-hanging exercises on the angle of trunk rotation in patients with adolescent idiopathic scoliosis (AIS). (2) Methods: Twenty-seven patients with AIS with a mean age of 18.6 years were retrospectively analyzed. The angle of trunk rotation (ATR) values were measured before and after performing semi-hanging and standing muscle cylinder exercises. Both exercises were performed for three to five respiratory cycles. The semi-hanging exercise was performed first, followed by the muscle cylinder exercise, in this order, in all participants. For statistical analysis, the Wilcoxon signed-rank test was used to analyze ATR changes after the exercises, and the Kruskal-Wallis test was used to compare ATR changes according to the main curve location. (3) Results: The thoracic, thoracolumbar and lumbar maximum ATR values were significantly increased after the semi-hanging exercise (p < 0.001) and decreased after the muscle cylinder exercise (p < 0.001). The ATR change was greater in the lumbar region than in the thoracic and thoracolumbar regions. (4) Conclusion: The results of this study of a small group of patients emphasized that one of the scoliosis-specific corrective exercises, the standing muscle cylinder exercise, improved ATR, while the other, the semi-hanging exercise, worsened ATR in patients with AIS. It is recommended that each scoliosis-specific corrective exercise be evaluated and redesigned to maximize the three-dimensional corrective effect, considering the biomechanics of the spine and the pathomechanics of scoliosis.

    Benchmarking the Anisotropy of Nitroxyl Radical Solvation With IR Spectroscopy
    (The Royal Society of Chemistry, 2024) Bras, Elisa M.; Zimmermann, Charlotte; FAUSTO, RUI; Suhm, Martin A.
    Two simple nitroxyl radicals, di-tert-butyl nitroxyl (DTBN) and 2,2,6,6-tetramethylpiperidinyloxyl (TEMPO) are solvated by one or two water, methanol, tert-butyl alcohol or phenol molecules. The resulting low temperature IR spectra of the vacuum-isolated microsolvates in the OH stretching range are assigned based on harmonic DFT predictions for closed shell solvent dimers and trimers and their offset from experiment, to minimise theory-guided assignment bias. Systematic conformational preferences for the first and second solvent molecule are observed, depending on the conformational rigidity of the radical. These assignments are collected into an experimental benchmark data set and used to assess the spectral predicting power of different DFT approaches. The goal is to find inexpensive computational methods which provide reliable spectral predictions for this poorly explored class of microsolvates.

    Reduced False Memory in the Second Language of Turkish-English Bilinguals
    (Routledge Journals, Taylor & Francis Ltd., 2024) Sıtkı, Merve; Ikier, Simay; ŞENER, NİLÜFER
    In the Deese-Roediger-McDermott (DRM) paradigm, studying a list of semantically related words leads to false memory for the critical non-studied word that is related to all the words in the study list. Previous studies questioning whether bilinguals are more prone to false memory in their first language (L1) or second language (L2) in the DRM paradigm revealed mixed results. The present study investigated the same question with Turkish-English bilinguals. The revised hierarchical model proposes that the link between the lexicon and the semantic system is weaker in L2 than in L1, suggesting that false memory in the DRM paradigm that relies on semantic relatedness would be higher in L1 than in L2. Furthermore, previous studies showed that L2 is more resistant to errors in decision-making when the two languages are dissimilar, but not when they are similar, and Turkish and English are historically distant and typologically dissimilar languages. We tested Turkish-English bilingual participants whose L1 is Turkish with Turkish and English DRM word lists that had similar prior norms for generating false recognition. In the recognition test, some of the studied items and the critical non-studied items were presented and participants identified the studied items. False recognition for the critical non-studied items was lower and correct recognition for studied items was higher in L2 than in L1. The results suggest that L2 is more resistant to false memory due to its weaker lexicon and semantic system associations, at least when the two languages spoken by the bilingual are dissimilar.

    NeuroBioSense: A Multidimensional Dataset for Neuromarketing Analysis
    (Elsevier, 2024) KOCAÇINAR, BÜŞRA; İNAN, PELİN; ZAMUR, ELA NUR; ÇALŞİMŞEK, BUKET; AKBULUT, FATMA PATLAR; Çatal, Çağatay
    In the context of neuromarketing, sales, and branding, the investigation of consumer decision-making processes presents complex and intriguing challenges. Consideration of the effects of multicultural influences and societal conditions from a global perspective enriches this multifaceted field. The application of neuroscience tools and techniques to international marketing and consumer behavior is an emerging interdisciplinary field that seeks to understand the cognitive processes, reactions, and selection mechanisms of consumers within the context of branding and sales. The NeuroBioSense dataset was prepared to analyze and classify consumer responses. This dataset includes physiological signals, facial images of the participants while watching the advertisements, and demographic information. The primary objective of the data collection process is to record and analyze the responses of human subjects to these signals during a carefully designed experiment consisting of three distinct phases, each of which features a different form of branding advertisement. Physiological signals were collected with the Empatica e4 wearable sensor device, considering non-invasive body photoplethysmography (PPG), electrodermal activity (EDA), and body temperature sensors. A total of 58 participants, aged between 18 and 70, were divided into three different groups, and data were collected. Advertisements prepared in the categories of cosmetics for 18 participants, food for 20 participants, and cars for 20 participants were watched. On the emotion evaluation scale, 7 different emotion classes are given: Joy, Surprise, anger, disgust, sadness, fear, and neutral. This dataset will help researchers analyse responses, understand and develop emotion classification studies, the relationship between consumers and advertising, and neuromarketing methods.

    Mechanistic Approach on Melatonin-Induced Hormesis of Photosystem II Function in the Medicinal Plant Mentha spicata
    (MDPI, 2023) Moustakas, Michael; Sperdouli, Ilektra; Adamakis, Ioannis-Dimosthenis S.; Sas, Begüm; İŞGÖREN, SUMRUNAZ; Moustaka, Julietta; Morales, Fermin
    Melatonin (MT) is considered a new plant hormone having a universal distribution from prokaryotic bacteria to higher plants. It has been characterized as an antistress molecule playing a positive role in the acclimation of plants to stress conditions, but its impact on plants under non-stressed conditions is not well understood. In the current research, we evaluated the impact of MT application (10 and 100 mu M) on photosystem II (PSII) function, reactive oxygen species (ROS) generation, and chlorophyll content on mint (Mentha spicata L.) plants in order to elucidate the molecular mechanism of MT action on the photosynthetic electron transport process that under non-stressed conditions is still unclear. Seventy-two hours after the foliar spray of mint plants with 100 mu M MT, the improved chlorophyll content imported a higher amount of light energy capture, which caused a 6% increase in the quantum yield of PSII photochemistry (Phi(PSII)) and electron transport rate (ETR). Nevertheless, the spray with 100 mu M MT reduced the efficiency of the oxygen-evolving complex (OEC), causing donor-side photoinhibition, with a simultaneous slight increase in ROS. Even so, the application of 100 mu M MT decreased the excess excitation energy at PSII implying superior PSII efficiency. The decreased excitation pressure at PSII, after 100 mu M MT foliar spray, suggests that MT induced stomatal closure through ROS production. The response of Phi(PSII) to MT spray corresponds to a J-shaped hormetic curve, with Phi(PSII) enhancement by 100 mu M MT. It is suggested that the hormetic stimulation of PSII functionality was triggered by the non-photochemical quenching (NPQ) mechanism that stimulated ROS production, which enhanced the photosynthetic function. It is concluded that MT molecules can be used under both stress and non-stressed conditions as photosynthetic biostimulants for enhancing crop yields.

    Neurophysiological and Biosignal Data for Investigating Occupational Mental Fatigue: MEFAR Dataset
    (Elsevier, 2024) Derdiyok, Şeyma; AKBULUT, FATMA PATLAR; Çatal, Çağatay
    The prevalence of mental fatigue is a noteworthy phenomenon that can affect individuals across diverse professions and working routines. This paper provides a comprehensive dataset of physiological signals obtained from 23 participants during their professional work and questionnaires to analyze mental fatigue. The questionnaires included demographic information and Chalder Fatigue Scale scores indicating mental and physical fatigue. Both physiological signal measurements and the Chalder Fatigue Scale were performed in two sessions, morning and evening. The present dataset encompasses diverse physiological signals, including electroencephalogram (EEG), blood volume pulse (BVP), electrodermal activity (EDA), heart rate (HR), skin temperature (TEMP), and 3-axis accelerometer (ACC) data. The NeuroSky MindWave EEG device was used for brain signals, and the Empatica E4 smart wristband was used for other signals. Measurements were carried out on individuals from four different occupational groups, such as academicians, technicians, computer engineers, and kitchen workers. The provision of comprehensive metadata supplements the dataset, thereby promoting inquiries about the neurophysiological concomitants of mental fatigue, autonomic activity patterns, and the repercussions of a cognitive burden on human proficiency in actual workplace settings. The accessibility of the aforementioned dataset serves to facilitate progress in the field of mental fatigue research while also laying the groundwork for the creation of customized fatigue evaluation techniques and interventions in diverse professional domains.

    Augmented Reality Experience in an Architectural Design Studio
    (Springer, 2023) Alp, Neşe Çakıcı; YAZICI, YASEMİN ERKAN; Öner, Dilan
    Thanks to the developing technology, different methods and tools are used in architectural representation, and architects contribute to developing these tools. Architects can easily model their designs with computer technologies and even make them visible in the environment with augmented reality technologies. Also, it is thought that these technologies will become widespread in basic architectural education over time. This study conducted a practice at the undergraduate architecture level using augmented reality technology. Within the scope of the study, the predisposition of students who experience augmented reality technologies to new representation, gender, course period, familiarity with playing computer games, the effect of computer programs that they can use in their previous augmented reality experience and designs if any, and the correlation between them has been tried to be revealed with this study. In this context, a study was carried out with thirteen students in the architectural design studio. Students were expected to parametrically design indoor exhibition elements using Rhinoceros 3D software and the Grasshopper plugin in the study. Then, an experimental augmented reality study was conducted with the Fologram, in which the students transferred these virtual exhibition elements they designed to the real indoors and reshaped them according to the space. Afterwards, a questionnaire consisting of five independent and ten dependent variables was applied to the students. The survey results were analysed with the IBM SPSS Statistics program. According to the results obtained, significant results were determined between 4 independent variables and one dependent variable.

    The Association of Child Abuse Experiences and Intolerance of Uncertainty in Young Adults
    (Routledge, 2023) Dirican, Ayşe Hatun; Kozak, Ekin Doğa; Kavakcı, Önder; SÖNMEZ, BERNA
    Objective: Drawing upon the identity disruption model, we investigated the association between child abuse experiences (emotional, physical, and sexual) and intolerance of uncertainty. We also addressed demographic differences in uncertainty intolerance in this study. Methods: Using online survey questionnaires, we collected data from a sample of 302 young adults in Turkey. The data were analyzed using confirmatory factor analysis, structural equation modeling, one-way analysis of variance, and independent samples t-test. Results: The results showed that of the three types of child abuse analyzed, only emotional abuse was significantly and positively associated with intolerance of uncertainty. In contrast, age was negatively associated with intolerance of uncertainty. Regarding demographic differences, we found that the level of intolerance of uncertainty differed based on young adults’ gender, psychiatric diagnosis, and education. Specifically, our findings indicated that intolerance of uncertainty is significantly higher in females compared to males. It is also significantly higher in young adults with a diagnosis for psychiatric disorders than those without. Moreover, intolerance of uncertainty is significantly higher in young adults who have a high school graduate degree than their undergraduate and graduate counterparts. We discussed how child abuse is associated with heightened intolerance of uncertainty in young adulthood as well as why demographic differences may exist in uncertainty intolerance. Conclusions: The present study expanded the existing research on the psychological consequences of childhood abuse experiences by linking child abuse to intolerance of uncertainty. Particularly, exposure to emotional abuse in early life can be a risk factor to cope with uncertainty in later life.

    An Investigation of the Relationship Between the General Vaccination Attitudes of Pregnant Women and Their Attitudes Toward the COVID-19 Vaccine
    (Routledge, 2023) Mamuk, Rojjin; Akgün, Meryem; MİRAL, MUKADDES TURAN; Göksu, Şerife
    This study aimed to investigate the relationship between the attitudes of pregnant women toward general vaccines based on the Health Belief Model and their attitudes toward the COVID-19 vaccine. The study, which was designed as a descriptive, cross-sectional, and correlational study, was conducted with 348 pregnant women in three public hospitals in Northern Cyprus between June 24 and November 28, 2022. Data were collected using the “Participant Information Form,” “Public Attitude Toward Vaccination Scale-Health Belief Model” (PAVS-HBM), and “Attitudes Toward the COVID-19 Vaccine” (ATV-COVID-19). The COVID-19 vaccination rate among pregnant women was quite high. Pregnant women have a high perception of sensitivity, importance, benefit, and health responsibility for routine vaccines and vaccination programs based on the HBM, and a low perception of barriers to vaccination. These results showed that pregnant women have a determined and positive attitude toward the acceptance of vaccines in general. On the other hand, the attitude of pregnant women toward the COVID-19 vaccine was moderately negative. Despite the reservations about the COVID-19 vaccine, a determined and positive attitude toward vaccines in general has increased acceptance of the COVID-19 vaccine.

    Functional Bandaging in Children with Idiopathic Toe-Walking
    (NLM (Medline), 2023) Tuncer, Deniz; AKALAN, NAZİF EKİN; Çalışkan, M. Mine; Temelli, Yener; Yiğit, Pakize
    Background: Idiopathic toe-walking (ITW) is a persistent gait pattern with no known etiology characterized as premature heel rise or no heel contact. We investigated the effects of functional bandaging in children with ITW on heel contact during stance phase and on gait quality. Methods: Nineteen children aged 4 to 16 years with ITW and ten age-matched healthy children were included in the study. Elastic adhesive bandages were applied to children with ITW to assist with dorsiflexion. Before bandaging (T0) and immediately (T1) and 1 week (T2) after initial bandaging, the initial contact, loading response, and midstance subphases of gait were analyzed using light pressure sensors and the Edinburgh Visual Gait Score (EVGS). Ten age-matched children with typical gait participated for comparison in T0. The data were analyzed with Friedman and Wilcoxon signed rank tests for within-group comparisons and Mann-Whitney U tests for between-group comparisons. Results: In T0, for the ITW group, no heel contact was observed during stance. In T1, all of the participants achieved heel contact at initial contact and loading response and 56.8% at midstance. In T2, all of the heels continued contact at initial contact and loading response and 54.3% at midstance. The EVGS significantly improved. The Friedman test showed that there were noteworthy improvements between T0-T1 and T0-T2 in video-based observational gait analysis and EVGSs (P < .001), although no difference was found between T1-T2 in video-based observational gait analysis (P = .913) and EVGSs (P = .450). Conclusions: In children with ITW, dorsiflexion assistive functional bandaging was an effective tool to help achieve heel contact on the ground and improve walking quality for a short period after application. Further studies with longer follow-up and larger sample sizes are required to confirm the long-term therapeutic effects of this promising functional bandaging.

    Analysis of Facial Emotion Expression in Eating Occasions Using Deep Learning
    (Springer, 2023) ELİF, YILDIRIM; AKBULUT, FATMA PATLAR; Çatal, Çağatay
    Eating is experienced as an emotional social activity in any culture. There are factors that influence the emotions felt during food consumption. The emotion felt while eating has a significant impact on our lives and affects different health conditions such as obesity. In addition, investigating the emotion during food consumption is considered a multidisciplinary problem ranging from neuroscience to anatomy. In this study, we focus on evaluating the emotional experience of different participants during eating activities and aim to analyze them automatically using deep learning models. We propose a facial expression-based prediction model to eliminate user bias in questionnaire-based assessment systems and to minimize false entries to the system. We measured the neural, behavioral, and physical manifestations of emotions with a mobile app and recognize emotional experiences from facial expressions. In this research, we used three different situations to test whether there could be any factor other than the food that could affect a person’s mood. We asked users to watch videos, listen to music or do nothing while eating. This way we found out that not only food but also external factors play a role in emotional change. We employed three Convolutional Neural Network (CNN) architectures, fine-tuned VGG16, and Deepface to recognize emotional responses during eating. The experimental results demonstrated that the fine-tuned VGG16 provides remarkable results with an overall accuracy of 77.68% for recognizing the four emotions. This system is an alternative to today’s survey-based restaurant and food evaluation systems.

    The effects of chronic stress on academic and professional achievement can have a substantial impact. This relationship is highlighted through a dataset that includes questionnaires and physiological data from a group of individuals. The questionnaire data of 48 individuals, the physiological data of 20 individuals during sessions with a psychologist, and the exam data of 8 individuals were analyzed. The questionnaire data collected includes demographic information and scores on the TOAD stress scale. Physiological data was captured using the Empatica e4, a wearable device, which measured various signals such as blood volume pulse, electrodermal activity, body temperature, interbeat intervals, heart rate, and 3-axis accelerometer data. These measurements were taken under different stress conditions, both high and low, during therapy sessions and an exam respectively. Overall, this study significantly contributes to our understanding of how stress affects achievement. By providing a large dataset consisting of questionnaires and physiological data, this research helps researchers gain a better understanding of the complex relationship between stress and achievement. It also enables them to develop innovative strategies for managing stress and enhancing academic and professional success.

    Adaptation, Reliability, and Validation of the Turkish Version of the Bad Sobernheim Stress Questionnaire-Deformity in Patients With Adolescent Idiopathic Scoliosis
    (Wolters Kluwer Health, 2023) Akçay, Burçin; Kuru Çolak, Tuǧba; APTİ, ADNAN
    Background:There is a limited number of disease-specific outcome measurement scales in Turkish, which can be used for individuals with adolescent idiopathic scoliosis (AIS). The aim of this study was to translate, adapt, and evaluate the validity and reliability of the Turkish version of the Bad Sobernheim Stress Questionnaire-Deformity (TRv.BSSQD) questionnaire in Turkish patients with AIS.Objective(s):After the translation and back-translation process, the TRv.BSSQD and Scoliosis Research Society-22 questionnaires were completed in face-to-face interviews with 49 patients with AIS. The TRv.BSSQD questionnaire was readministered to the same patients 2 weeks later to assess test-retest reliability.Results:The Cronbach alpha value calculated for internal reliability was 0.806. The intraclass correlation coefficient values of the items of the TRv.BSSQD ranged from 0.809 (P < 0.001) (question 8) to 0.955 (P < 0.001) (question 7). The test-retest correlation coefficient for the item-total score was 0.960 (P < 0.001). Validity analysis showed a significantly positive correlation between the TRv.BSSQD total score and pain, self-image, and mental subgroup and the total scores of the SRS-22r scale (P < 0.05).Conclusions:This patient-reported outcome instrument, the TRv.BSSQD, showed good internal consistency, good reliability with test-retest analysis, and construct validity, suggesting that it is an appropriate assessment instrument for Turkish patients with AIS.
