Patient safety in the pandemic: Experiences of charge nurses.

AIM: The aim of this study was to identify charge nurses' experiences ensuring patient safety during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: The research was conducted with charge nurses between July 2021 and February 2022. Research data were collected using a semi-structured interview with two main questions, six sub-questions and an audio recording. Interviews were conducted with 12 charge nurses and lasted ≈30 min. The content analysis method was used to transfer the collected data to written documents and define them to analyse the individual interview data. Content analyses were conducted independently by three different researchers. Inclusion and exclusion criteria for content were established to ensure consistency among all researchers. Researchers independently developed a coding scheme for content analysis based on the research objectives and applied it to the content. Intercoder reliability was assessed with Cohen's kappa coefficient to measure the consistency of coding among researchers. RESULTS: Three main themes were identified as a result of the content analysis. The themes identified after independent examination by the three researchers were 'ensuring safety and protection', 'sustaining motivation and resilience' and 'organizational restructuring and challenges'. CONCLUSIONS: This study highlights the challenges faced by charge nurses during the COVID-19 pandemic and their critical role in maintaining patient safety. The findings emphasize the importance of organizational adaptability, continuous motivation and comprehensive risk management strategies. Charge nurses played a key role in enhancing safety measures and fostering a culture of resilience among healthcare staff. Moving forward, these insights should guide health policies and practices to better prepare for future public health crises, ensuring the safety of both patients and staff.

Development and psychometric validation of the Sickness Presenteeism Scale-Nurse.

AIM: This study's aim is to develop and psychometrically assess the Sickness Presenteeism Scale-Nurse. BACKGROUND: Evaluation of the effects of sickness presenteeism on nurses' performance and productivity is important for healthcare quality. DESIGN: This was an instrument development and validation study. METHODS: Scale items were created based on literature review and qualitative research. Data were collected from 619 nurses between October and December 2021. The factor structure of the scale was determined by explanatory and confirmatory factor analysis performed with different sample groups. Convergent and discriminant validity were investigated, and reliability was evaluated with Cronbach's α values, adjusted item-total correlation, composite-reliability and split-half reliability. RESULTS: Explanatory factor analysis showed that Sickness Presenteeism Scale-Nurse consisted of four sub-dimensions and 21 items and explained 57.9% of the total variance. This factor structure was confirmed by confirmatory factor analysis. The convergent and discriminant validity was confirmed. The total Cronbach's α value of the scale was calculated as 0.928, with Cronbach's α values of the sub-dimensions calculated as 0.815-0.903; composite reliability values were calculated as 0.804-0.903. CONCLUSIONS: The Sickness Presenteeism Scale-Nurse is a valid and reliable measurement instrument that can be used to evaluate the effect of nurses' sickness presenteeism behaviour on job performance.

Investigation of the peripheral inflammation (neutrophil-lymphocyte ratio) in two neurodegenerative diseases of the central nervous system.

INTRODUCTION: Alzheimer's disease (AD), and idiopathic Parkinson's disease (IPD) are the neurodegenerative diseases of the central nervous system (CNS). Cognitive impairment is on the forefront in AD. However, IPD is a movement disorder. Inflammation was suggested to have an effect in the pathophysiology of these two diseases. Neutrophil-lymphocyte ratio (NLR) was shown to be a possible marker showing the peripheral inflammation. We aimed to investigate the NLR of patiens with the diagnosis of AD, and IPD, and individuals with no neurodegenerative disease. MATERIALS AND METHODS: A total of 100 patients with the diagnosis of IPD, and 94 with diagnosis of AD, and 61 healthy controls were included into the study. All the demographic, clinical, and laboratory data were retrospectively obtained from the hospital automated database system. RESULTS: The NLR in the IPD group was found statistically significantly higher compared with the control group and the AD group (p < 0.001, p = 0.04, respectively). The age-adjusted values were statistically analyzed because of age difference. No statistically significant difference was detected between AD and control groups in terms of NLR (p = 0.6). The age-adjusted NLR value in the Parkinson's group was found significantly higher compared to the control group (p = 0.02) and Alzheimer's group (p = 0.03). DISCUSSION: Chronic inflammation has an important role in the emergence and progression of the chronic neurodegenerative diseases of the CNS. Our results show that the inflammation in the peripheral blood in IPD was more significant compared with the inflammation in AD.

Medical error reporting software program development and its impact on pediatric units' reporting medical errors.

OBJECTIVE: The purpose of this quasi-experimental study was to developing web-based, anonymous reporting system to increase reporting of medication errors, blood transfusion errors and patient falls in pediatric units and to compare the computerized system with the written system already in use at the institution. METHODS: This study was conducted in all pediatric units of a research hospital. All physicians and nurses working in these units agreed to participate in the study. All units were visited to introduce the new reporting system. The number and quality of the reports sent on the new system in years 2014 and 2015 were compared to the reports sent the previous year using the written system. RESULTS: There was considerable increase in rates of reporting: 234% increase in medication error reporting rate, and 100% increase in the reports of blood transfusion errors. One of the most important results of this study that near-miss errors were not reported at all while the written system of the study institution was being used, whereas it was the most commonly reported type of errors in the electronic error reporting system. CONCLUSION: The web-based reporting system, which makes reporting easy, promoted the development of safety culture among doctors and nurses in common language.

Comparison of thyroid function tests and blood count in pregnant women with versus without gestational diabetes mellitus.

AIM: The aim of this study was to compare thyroid function and complete blood count parameters in pregnant women with versus without gestational diabetes mellitus (GDM). METHODS: A total of 269 pregnant women patients with (n = 110, GDM group) or without (n = 159, non-GDM group) GDM were included in this study. Data on age, rate of cesarean section, birthweight of neonate, hemogram, and thyroid function tests were collected. Multivariate analysis was performed to determine factors predicting increased risk of GDM. RESULTS: Rate of cesarean section (70.9 vs 57.2%, P = 0.022), median (max-min) age (33.0 [26.0] vs 26.0 [20.0] years, P < 0.001), platelet count (246.7 ± 68.3 vs 227.8 ± 64.2 ×103 /µL, P = 0.021) and thyroid-stimulating hormone (1.3 [97.6] vs 1.0 [4.1] µIU/mL, P = 0.028) were significantly higher in the GDM than in the non-GDM group; whereas mean platelet volume (10.4 [5.3] vs 10.6 [5.6] fL, P = 0.031) and free triiodothyronine (FT3) (2.9 [3.6] vs 3.1 [3.0] pg/mL, P < 0.001) levels were significantly lower in the GDM than in the non-GDM group. Older age (odds ratio, 1.281; 95% confidence interval, 1.182-1.389, P < 0.001) and lower FT3 levels (odds ratio, 0.295; 95% confidence interval, 0.149-0.586, P < 0.001) were independently associated with increased risk of GDM. CONCLUSION: Our findings revealed that lower FT3 levels and older age predict the likelihood of developing GDM in euthyroid pregnant women, with no influence of other thyroid hormones or blood counts on the risk of GDM.

Nerve conduction study and gastrocnemius H reflex response in rheumatoid arthritis.

BACKGROUND AND PURPOSE: We aimed to evaluate nerve conduction studies and gastrocnemius H reflex responses in rheumatoid arthritis (RA) patients and compared to the healthy adult subjects. METHODS: Twenty-six RA patients and twenty-two healthy adult subjects were included in the study. The nerve conduction study (NCS) findings and bilateral gastrocnemius H reflex responses were evaluated in all the groups. Age, gender, subcutaneous nodules, joint deformities, laboratory parameters, duration of disease, anti-rheumatic drug and steroid usage were recorded. Activity of disease was assessed using a 28-joint disease activity score (DAS28).The functional status was measured using the health assessment questionnaire (HAQ), pain intensity measured using a visual analog scale (VAS). RESULTS: The rate of electroneuromyographic (ENMG) abnormalities was 73% in RA patients. The most common diagnosis was carpal tunnel syndrome (61.4%). There were no significant correlations between ENMG findings and clinical and laboratory features evaluated. Right H reflex latencies were statistically longer in RA patients (p=0.03). According to calculated cut-off levels, there were more subjects with longer H reflex latencies in RA patients. CONCLUSION: In this study, entrapment neuropathies were found common as independent identity from duration and severity of disease in RA patients. For H reflex latencies, cut-off values were longer in RA patients. It may provide information about the early neuropathic involvement of long peripheral nerves in RA patients. But this findings are needed to be supported by larger population study.

Interleukin 18 gene polymorphism is a risk factor for multiple sclerosis.

Proinflammatory cytokines with immunosuppressive properties play an important role in the pathogenesis of multiple sclerosis (MS). Interleukin 18 (IL-18) is one of the most important innate cytokines produced from macrophages in the early stages of the inflammatory immune response. The purpose of this study was to determine whether there was any relationship between IL18 gene polymorphisms and MS. IL18 genotyping were performed in 101 MS patients and 164 control subjects by using the PCR-restriction fragment length polymorphism (PCR-RFLP) method. The frequency of MS patients with the CC genotype of the IL18 gene at position -137 was significantly higher than with the GG genotype [p = 0.01, odds ratio (OR) 3.17]. In haplotype analysis of two SNPs in the IL18 gene, frequency of the CC haplotype was significantly higher in MS patients (p = 0.002, OR 3.0). However, the genotype distribution of the IL18 -607 C/A polymorphism in the MS patient group was not significantly different from that of the control group. These data suggest that IL18 gene polymorphisms at position -137 might be a genetic risk factor for MS in the Turkish population.

Anti-GAD Encephalitis Following COVID-19 Vaccination: A Case Report.

Since December 2020, a significantly higher number of people worldwide have been vaccinated for coronavirus disease 2019 (COVID-19). Neurological complications have been reported after these vaccines, although a definitive causal relationship has not been proven in the available literature. We describe a 51-year-old man presenting with anti-glutamic acid decarboxylase (anti-GAD) antibody positive autoimmune encephalitis with progressive cognitive impairment and behavioral abnormalities, presenting shortly after the second dose of mRNA COVID-19 vaccine, possibly representing a serious vaccine-related adverse event. Response to high-dose steroid and intravenous immunoglobulin treatment was positive. As many people around the world have been vaccinated against COVID-19, this case shows that autoimmune encephalitis and even anti-GAD antibody positive autoimmune encephalitis can develop as a side effect after this new vaccine, but with early diagnosis and appropriate treatment, the clinic can have a good prognosis. Observational studies with large numbers of patients are needed to explain causality.

Developing the pediatric surgery patient satisfaction scale and assessment of its validity and reliability.

Aim of this study was to develop a patient satisfaction scale for needs and expectations of pediatric surgery patients and to propose a new measurement tool in this field. Population of study consisted of all patients between May 2018 and February 2020 at a pediatric surgery service of a university hospital in Turkey. A pool of 70 items was prepared for scale. Two items were removed in line with expert opinions and suggestions. As a result of content validity and test application, 36 items were removed, and scale was revised. Data were transferred to SPSS Statistics 23 and AMOS 22 program. After evaluating scope validity of scale, Content Validity, Structural Validity, Exploratory Factor Analysis, and finally Reliability Analysis were examined. As a result of the analyses, 32 items with eight sub-dimensions were obtained from scale. Eight-factor scale explained 60.42% of total variance. Cronbach Alpha internal consistency of scale was found to be 0.88. Item factor loads of scale were created and the reliability of scale were obtained at desired level. The scale is suitable for patients aged 6 to 18 years old.

Use of follow-on fingolimod for multiple sclerosis: Analysis of effectiveness and patient reported outcomes in a real-world clinical setting.

BACKGROUND: Follow-on disease modifying therapies (FO-DMTs) do not always require Phase III studies. There are concerns that cheaper FO-DMTs are only used to reduce healthcare costs. However, the well-being of people with MS (pwMS) should be a priority. We aimed to evaluate the efficacy, safety and treatment satisfaction of one of the FO- Fingolimod (FTY) used in Turkey with the approval of Turkish Ministry of Health. METHODS: PwMS under FTY were recruited from 13 centers and real-world data and answers of satisfaction and adherence statements of pwMS on FTY treatment were analyzed. RESULTS: Data of 239 pwMS were obtained. The duration of FTY treatment was 2.5 ± 0.8 (1-4) years in pwMS who were included in the study and whose treatment continued for at least one year. Significant decreases in annual relapse rate (p < 0.001), Expanded Disability Status Scale (p < 0.001) and neuroimaging findings (p < 0.001) were observed. While 64% of the patients were satisfied and 71.5% were found to adherent with this FO-FTY. CONCLUSION: This multicenter retrospective study found that the efficacy, safety and treatment adherence of a prescribed FO-FTY were consistent with the results of real-world studies. Studies including real-world data may provide guidance to address issues related to FO-FTY use.

Clinical and Demographic Characteristics and Two-Year Efficacy and Safety Data of 508 Multiple Sclerosis Patients with Fingolimod Treatment.

Introduction: Fingolimod is the first oral immunomodulatory treatment used as secondary care therapy in the treatment of multiple sclerosis for the last 10 years. The objective of our study is to reveal the experiences of the first generic fingolimod active ingredient treatment in different centers across Turkey. Method: The first generic fingolimod efficacy and safety data of patients followed-up in 29 different clinical multiple sclerosis units in Turkey were analyzed retrospectively. Data regarding efficacy and safety of the patients were transferred to the data system both before the treatment and on the 6th, 12th and 24th month following the treatment. The data were analyzed using the IBM SPSS 20.00. P value of <0.05 was considered to be statistically significant. Results: A total of 508 multiple sclerosis patients, 331 of whom were women, were included in the study. Upon comparing the Expanded Disability Status values before and after the treatment, a significant decrease was observed, especially at month 6 and thereafter. Since bradycardia occurred in 11 of the patients (2.3%), the first dose had to be longer than 6 hours. During the observation of the first dose, no issues that could prevent the use of the drug occured. Side effects were seen in 49 (10.3%) patients during the course of fingolimod treatment. Respectively, the most frequent side effects were bradycardia, hypotension, headache, dizziness and tachycardia. Conclusion: The observed results regarding efficacy and safety were similar to clinical trial data in the literature and real life data in terms of the first equivalent with fingolimod active ingredient.

Comparison of retinal nerve fibre layer thickness with visual evoked potential and visual field in patients with multiple sclerosis.

BACKGROUND: To evaluate retinal nerve fibre layer thickness and to compare results with visual evoked potentials and visual field in patients with multiple sclerosis. DESIGN: A prospective, case-control study, university hospital setting. PARTICIPANTS: Seventy-three eyes of 37 multiple sclerosis patients and 74 eyes of 37 healthy subjects. METHODS: All patients underwent a complete neurological and ophthalmological examination and peri-papillary retinal nerve fibre layer thickness was evaluated using scanning laser polarimetry (GDx). Furthermore, visual evoked potential and visual field testing were performed. MAIN OUTCOME MEASURES: The χ(2) test, Student's t-test, Mann-Whitney U-test and Pearson's correlation coefficient analysis of the GDx, visual evoked potential and visual field testing parameters. RESULTS: GDx measurements showed significantly more retinal nerve fibre layer damage in the patients than in the control groups. Comparison of the GDx parameters between patients with optic neuritis and non-optic neuritis demonstrated a statistically significant difference in symmetry (P = 0.046) and superior/nasal parameters (P = 0.009). A correlation was found between the number, superior and inferior ratio parameters, and P100 amplitude obtained with visual evoked potential in patients with non-optic neuritis. Additionally, there was a correlation between the number, inferior ratio and superior/nasal parameters, and the mean deviation of visual field in the non-optic neuritis group. CONCLUSIONS: For retinal nerve fibre layer thickness measurements in multiple sclerosis patients, the GDx, along with other techniques, such as visual evoked potential, can be used as a diagnostic and follow-up criterion, particularly in patients without optic neuritis.

Abdominal wall endometriosis in the cesarean section surgical scar: a potential diagnostic pitfall.

AIM: The abdominal wall is an uncommon site of extrapelvic endometriosis. It usually develops in a previous surgical scar and should be considered in the differential diagnosis of any abdominal swelling. Classical symptoms of endometriosis may resemble abdominal wall lesions such as an incisional hernia, hematoma, granuloma, abscess or various soft tissue tumors; therefore, a definitive preoperative diagnosis is not always easy to determine in every case. The aim of this article is to review the clinical findings, imaging results and histopathology of those of our patients who have had cesarean scar endometriosis. METHODS: Patients diagnosed with abdominal wall endometriosis in their surgical scars from February 2008 to March 2010 were documented. The age, parity, symptoms, previous surgeries, initial diagnosis, diagnostic modalities, definitive operation, postoperative complications, histopathological evaluations and recurrences were recorded and analyzed. RESULTS: There were 18 patients with a mean age of 34.5 ± 9.6 years. All (100%) had a gradually growing nodular abdominal mass in or adjacent to their cesarean incision scars. This was often associated with pain (83.3%), either noncyclical (26.6%) or cyclical (73.3%) in nature. Ultrasonography (100%), computerized tomography with intravenous contrast (22.2%) and/or magnetic resonance imaging (66.6%) were performed on the patients. All patients underwent surgery and their masses were completely excised. The mean diameter of the removed masses was 3.9 ± 1.4 cm. The final pathological diagnosis for each case was abdominal wall endometriosis. Biannual follow-up examinations for two years revealed that each patient had a complete and uneventful recovery without recurrence. CONCLUSION: Abdominal wall endometriosis should be considered in the differential diagnosis of masses located at cesarean section incision scars, which should be excised for definitive diagnosis and treatment.

Granulomatous mastitis: is it an autoimmune disease? Diagnostic and therapeutic dilemmas.

PURPOSE: Granulomatous mastitis (GM) is a rare benign inflammatory breast disease. The clinical presentation of granulomatous mastitis usually mimics malignancy or infection. The aim of this study was to review the clinical and diagnostic features of GM and discuss the medical and surgical treatment of our series of eight GM patients. METHODS: Between 2008 and 2010, eight patients were diagnosed with GM and underwent surgery. Patients were evaluated clinically and radiologically. The diagnosis of GM was confirmed in all cases by core needle or excisional biopsies. Serological tests were performed for rheumatoid factor (RF), antinuclear antibody (ANA), and anti-double-stranded DNA (anti-dsDNA). RESULTS: The mean patient age was 37 years. Common presenting symptoms were a hard mass, pain, inflamed hyperemic skin, and sinus formation. Serological tests for RF were positive in 6 patients, and ANA and anti-dsDNA antibodies were detected in 2 patients. All patients underwent antibiotic therapy before surgery, and were treated with wide surgical excision with negative margins. Methylprednisolone (16 mg/day for 3 months) therapy was used in 3 patients (all RF and 2 ANA/anti-dsDNA positive) following a wide excisional biopsy after a postoperative recurrence mimicking skin lesions was seen. These patients responded well to steroid therapy. CONCLUSIONS: The diagnosis of GM should be made carefully to avoid a misdiagnosis. Steroid therapy should be considered based on the idea that this is an autoimmune disease.

Delivery in female kidney transplant recipients with hepatitis C virus infection: is it safe for mother and newborn?

The aim of this report is to evaluate whether pregnancy is a risk factor for poor outcome of infection with hepatitis C virus or for allograft deterioration among kidney transplant recipients. The first case was in a 41-year-old pregnant kidney transplant recipient with hypercreatinemia and a history of toxic hepatitis. The second case was treated with interferon before transplant. Tacrolimus-based immunosuppressive regimens were used during the pregnancies. Hypertension complicated both pregnancies, and the pregnancies ended with cesarean delivery at preterm and term with healthy but low-weight newborns. The first patient became positive for hepatitis C virus RNA after pregnancy without a flare in transaminase level. Antibodies to hepatitis C virus were negative in the newborns. In conclusion, pregnancy should be promoted for kidney recipients infected with hepatitis C virus who have stable graft and liver function.

Mapping the evidence-based practice research field in nursing from 1995 to 2021: A bibliometric analysis.

BACKGROUND: Evidence-based nursing and its practices are increasing rapidly in the health and nursing literature. A holistic image of evidence-based nursing research is needed to address evidence-based studies and available information on nursing. AIM: The aim of this study was to evaluate evidence-based nursing-related research with bibliometric analysis in order to provide a structured macroscopic overview of its features and advances. METHODS: A bibliometric analysis of 4,159 publications from 1995 to 2021 was performed to map the literature of evidence-based nursing studies and assess the structure of the scientific community. The studies' publication output and growth trend, authors and collaborations, publishing journals, terms, current trends, subject categories, global distribution and collaboration, and the authors' average number of citations were all assessed. RESULTS: It was found that the number of evidence-based nursing publications increased until 2016, reaching the publication peak (n = 369), after which they began to decline. Most studies on the topic (n = 543) have been published in the journal Worldviews on Evidence-Based Nursing. Evidence-based knowledge, dissemination, implementation, implementation barriers, and implementation and training curricula in particular fields have all evolved over time as the key concepts of research. The United States (6,218), Australia (1,247), and England (790) are the three nations with the highest number of publications. On the other hand, it is seen that the subject has yet to be discussed in a few developing or underdeveloped countries. CONCLUSIONS: In the last 12 years, evidence-based nursing has been a comprehensive area of research. In comparison with the research areas in its field, it can be speculated that it has a more practical focus. It was determined that the authors' keywords primarily began with research implementation, practice development, and knowledge utilization over time, and then evolved to specific areas, educational areas, process applications, and important current topics such as Covid19.

Change management experiences of nursing students in clinical practice: A phenomenological study.

BACKGROUND: In healthcare services, nurses' roles and practices make them an integral component of the change process. Therefore, nurses should prepare for their change-creating roles during their education. However, little research regarding change management and the change creation process of nursing students is found in the literature. OBJECTIVES: To identify the needs of undergraduate nursing students when initiating change in practice and to reveal their experiences during the planning and implementation process of change projects. DESIGN: A descriptive, qualitative design using focus group was conducted. PARTICIPANTS: The study includes third-year undergraduate nursing students enrolled in a nursing school in Turkey and were enrolled in the Management in Nursing and Clinical Practices courses. METHODS: Six focus group were conducted with a total of 28 nursing students. Data were collected over one semester via a semi-structured form. The data were analyzed using thematic content analysis. RESULTS: Regarding the change management experiences of the participants, five main themes ("changing world, changing necessities," "view from the perspective of change," "discovering resistance," "developing motivation against resistance," and "change in the perception of change"), and nine sub-themes were determined. CONCLUSIONS: As a result of their change management experiences, nursing students might better contribute to the quality of patient care, think more critically and have more autonomy. Therefore, change process management should be extensively included in nursing education and should be systematically monitored.

Scientific View of the Global Literature on Medical Error Reporting and Reporting Systems From 1977 to 2021: A Bibliometric Analysis.

BACKGROUND: Error reporting is vital for the prevention of medical errors. Despite the importance of error reporting, underreporting of medical errors is a common reality in many countries. Therefore, barriers to error reporting and reporting systems are a constantly evolving field of research. For this reason, studies on medical error reporting and reporting systems should be evaluated multidimensionally. AIM: The aim of this study is to evaluate the global research on medical error reporting and reporting systems through bibliometric analysis to obtain a structured macroscopic overview of the features and developments. METHODS: A bibliometric analysis of 1464 publications from 1970 to 2021 was performed to map the literature of medical error reporting and assess the structure of the scientific community. RESULTS: After 2000, the number of publications increased annually until a maximum of 2020 was reached. The International Journal for Quality in Health Care and the Journal of Patient Safety have been the most productive journals when it comes to publishing on the subject. Trend topics of keyword plus have changed over time. The United States (1399), England (580), and Australia (478) are the 3 nations with the highest number of publications. On the other hand, it is seen that the subject has yet to be discussed in a few developing or underdeveloped countries. CONCLUSIONS: This bibliometric analysis shows that the number of publications and authors and cross-country cooperation are low regarding error reporting. The low number of publications and the lack of cooperation, especially in developing countries, reveal the importance of global cooperation.

Validity and Reliability of SCOPA Sleep Scale Turkish Version in Parkinson's Disease.

Introduction: The aim of this study was to form the Turkish adaptation of the SCOPA-SleepScale to be used in evaluating sleep quality in individuals with Parkinson's disease and to test its psychometric properties. Method: Data for this methodological study was collected between May and December 2017 in the neurology outpatient clinic of a hospital through face to face interviews with patients with a diagnosis of Parkinson's disease. The sample of the study consisted of 105 patients of 18 years of age and above with no additional neurological diseases who volunteered for the study. The SCOPA Sleep Scale was translated into Turkish through translation and back translation, and expert views were taken to test content validity. The reliability analyses of the scale were performed using item- total score correlations, test-retest correlations, and internal consistency. Exploratory factor analyses were conducted for construct validity and the Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS) were applied for criterion validity. The appropriateness of data for factor analysis was examined using the Kaiser-Meyer-Olkin (KMO) and Bartlett's tests. Results: The factor loads of the SCOPA Sleep Scale varied between 0.743 and 0.901, and the Turkish version of the scale exhibited a two factor structure in compliance with the original scale. The Cronbach`s alpha coefficient was found 0.907 for the nighttime sleep sub-dimension and 0.906 for the daytime sleepiness sub-dimension. In the test-retest evaluation, a correlation of 0.948 was obtained in the nighttime sleep sub-dimension of the scale and a correlation of 0.956 was obtainedin the daytime sleepiness sub-dimension of the scale. The nighttime sleep sub-dimension of the scale showed a positive correlation with PSQI, while the daytime sleepiness sub-dimension showed a positive correlation with ESS. Conclusion: The Turkish form of the SCOPA Sleep Scale is a valid and reliable tool to evaluate the sleep quality of individuals with Parkinson's disease.
