Arabic validation and cross-cultural adaptation of climate anxiety scale

BackgroundClimate change is an enduring global phenomenon that describes a long-lasting effect of change in weather and temperature of the earth. This study aimed to validate an Arabic version of the Climate Anxiety Scale (ACAS) to assess the anxiety associated with climate change. MethodsA cross-sectional survey was conducted using both online via Google Forms and face-to-face via hard copies, in five Arab countries, Lebanon, Palestine, Egypt, Saudia Arabia, and the United Arab Emirates). The internal consistency of the scale was assessed using the Cronbach's alpha. Exploratory factor analysis (EFA) conducted over principal component analysis assessed the scale dimensionality. Then, confirmatory factor analysis was conducted to investigate the EFA hypothesis of ACAS on anxiety about climate change. ResultsOf the 350 participants, 54.9 % were female, 77.7% lived in urban areas, 15.4% were from North Africa, 46.6 % were from Arab Gulf countries, and 38.0 % were from Bilad Al-Sham. Nearly two-thirds (62.3%) were single, 72.3% had a university degree, 94.9% were aware of climate change, 38.3 % participated in environmental protection programs, and 62.3% reported climate-related anxiety. The item content validity index (CVI) was 0.82–1.00, and the scale CVI (S-CVI) was 0.95. Overall Cronbach's alpha was 0.925 with a 95% confidence interval (CI) [0.902–0.940]. The Kaiser-Mayer-Olkin (KMO) test was 0.93, and Bartlett's test was significant (χ2 = 2762.6 p < 0.001). Bifactor model indices showed high explained common variance (ECV) (0.78), ωH (0.85), relative omega (0.91), H index (0.93), and factor determinacy (FD) (0.96) for the general factor. The general factor explained 78% of the common variance, whereas the group factors shared 22.0%. Model reliability coefficient omega (omega/omega S) for general factor, functional domain, and cognitive domain were 0.94, 0.92, and 0.89, respectively, suggesting a satisfactory fit threshold. ConclusionsThe ACAS tool is valid and reliable for assessing anxiety-related climate change among the Arab Population.

The Validity-Reliability Study of Turkish Version of Electronical Symptom Screening Tool (8-18) in SSPedi-Pediatric Patients with Cancer

Objective: The first step in symptom management is symptom screening which is necessary to keep the symptom under control. This study aimed to determine the validity and reliability of the Turkish version of the Electronic Symptom Screening Tool in Pediatrics for children aged 8-18 (SSPedi 8-18) with cancer. Methods: The research was conducted between September 2020 and June 2021. The sample in our study consists of 80 children (8-18 years) with cancer. For content validity, the scale was first translated into Turkish and then adapted using Davis’ correspondence analysis technique. The construct validity of the scale was assessed using the Barlett test and Kaiser-Mayer Olkin. For the scale’s reliability, Cronbach Alpha Reliability Coefficient, Equivalent Forms Method, bisection method and Item Total Score Correlation Coefficient correlation tests were analyzed. Before starting the study, ethics committee approval and written permits from institutions and individuals were obtained. Results: The content validity index was found between 0.93 and 1. The reliability of the scale of the equivalent form method was r:0.57, and bisection method was r:0.85 and the Cronbach internal consistency coefficient of scale=0.86. The correlation coefficient between the items and the total score was greater than r=0.20. The Kaiser-Meyer-Olkin coefficient was 0.82. The χ2 value (Bartlett test) was statistically significant (p= .001). Conclusion: The SSPedi 8-18 is a reliable and valid tool that can be used to assess the symptoms of Turkish children with cancer. Nurses’ use of the scale while providing nursing care to children diagnosed with cancer and their families will guide them in objectively determining symptoms, understanding the relationship between symptoms, and managing symptoms.

Determinants of the development of photovoltaics in Poland

The photovoltaic (PV) industry is a rapidly growing sector of the Polish economy. The motivation for this study is the lack of detailed research on the impact of external factors on PV development in Poland. Therefore, we consider the different interests of various participants in the industry, encompassing installers; engineering, procurement and construction; designers; distributors; and manufacturers. The main objective of the study is to identify and analyse the legal, economic, environmental, technical and social factors that influence the development of PV in Poland and their determinants, considering the specific needs of different market stakeholders. The research is based on analysing the literature, publicly available reports and websites to complement the findings from in-depth interviews and surveys conducted among key PV market participants. Computational methods are employed, including Bartlett's sphericity tests, and the adequacy of the correlation matrix is evaluated using the Kaiser–Mayer–Olkin coefficient. The research results identify the main determinants of PV industry development in Poland, which include the lack of connection capacity, the cost of non-RESs and hourly pricing in the prosumer billing system. The study also determines the different perspectives between market stakeholders, finding that social factors have little impact on PV industry development. The main conclusion of the study is that the identified barriers must be addressed and removed to ensure the stable development of PV in Poland.

Analisis Faktor Keterlambatan Pekerjaan Konstruksi Drainase dengan Menggunakan Metode Kaiser Mayer Oklin (KMO)

This research aims to identify factors that cause delays in implementing the Urban Drainage project in Kepatihan Village, Bojonegoro Regency, using Regional Revenue and Expenditure Budget (APBD) funds. The research method used a population involved in drainage construction, using a saturated sampling technique with 39 respondents. Data collection used questionnaires for primary data and secondary data obtained from project schedules, cost budget plans and workforce data. Data analysis uses factor analysis, descriptive analysis, and cross tabulation analysis. Factor analysis uses the Kaiser Mayer Olkin Measure of Sampling Adequacy (KMO-MSA) method. The KMO test was carried out with a significance value from the Bartlett Sphericity Test of less than 0.05 to determine the suitability of the variables. The KMO-MSA process is carried out by calculating the Kaiser Mayer Olkin (KMO) value. The KMO value ranges between 0 and 1, where a higher value indicates a better match. Apart from that, Bartlett's Test of Sphericity was also carried out to test the significance of the relationship between variables. If the test results are significant (p &lt; 0.05), then these variables are suitable for proceeding to further factor analysis. The results of the cross-tabulation analysis show that the labor variable (X2) is the main factor influencing delays in drainage construction projects, with a significance value (sig) &lt; 0.05. Based on the results of the descriptive analysis, the labor factor indicator (X2) which is the factor that has the most significant influence on construction project delays, is the variable X2.1 in the form of labor availability with a mean of 5.67 and a percentage value of 5.12%. This suggests that a lack of labor can cause delays in project implementation, potentially affecting overall project progress and quality.

Reliability and validity of the training satisfaction questionnaire for family members (TSQ-FM) entering the ICU during an isolation disease outbreak

BackgroundThe presence of family members in an isolated ICU during an isolation disease outbreak is restricted by hospital policies because of the infectious risk. This can be overcome by conferring to family members the skill and the ability to safely don and doff the personal protective equipment (PPE) through a nurse-led training intervention and assess their satisfaction, to respond to the need to define a safe, effective and quality care pathway focused on Family-Centered Care (FCC) principles. Objectivethe study aimed to build a valid and reliable instrument for clinical practice to assess family members’ satisfaction to allow ICU nurses to restore family integrity in any case of infectious disease outbreak that requires isolation. MethodsA cross-sectional study was conducted to test the psychometric properties. The questionnaire was constructed based on a literature review on the needs of family members in the ICU. 76 family members were admitted to a COVID-ICU. Cronbach's coefficient, Geomin rotated loading, and EFA were applied to assess the reliability and validity of the instrument. ResultsThe Kaiser-Mayer-Olkin (KMO) measure was 0.662, the Bartlett sphericity test showed a significant p-value (χ²=448.33; df=45; p < 0.01), Cronbach's alpha coefficient was.896. A further CFA analysis confirmed that all fit indices were acceptable. The results showed satisfactory validity and reliability, which could be generalized and extended to any outbreak of isolation disease. ConclusionsThis study provides a valid and reliable instrument for clinical practice to maintain family integrity in the dyadic relationship between the patient and the family member, even during an emergency infectious disease outbreak that requires isolation.

Development of the home environment risk rating scale and investigation of the psychometric properties in the elderly and adult individuals.

To reduce home accidents, which is one of the critical public health problems, it is necessary to evaluate the home environment first. The aim of this study was to develop the Home Environment Risk Rating Scale (HERRS) and examine its psychometric properties in elderly and adult individuals. This study was conducted on 220 elderly and adult individuals (63.68±10.31 years old, 68.2% female, 31.8% male) living in their homes. The participants completed the Sociodemographic Information Form, Home Environment Conditions Evaluation Form for Falls, and Home and Environment Risk Rating Scale. In addition, psychometric measurement results for horizontal and vertical measurements were analyzed by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) methods. It was found that the Kaiser-Mayer-Olkin (KMO) value for horizontal and vertical measurements were 0.613 and 0.704, respectively. Results of EFA for horizontal and vertical measurements revealed that five factors together explain 72.033% and three factors together explain 68.368% of the total variance, respectively. The result of CFA for horizontal and vertical measurements demonstrate that the 5-sub-dimension horizontal scale structure and the 3-sub-dimension vertical measurement structure generally fit acceptable in this scale. Cronbach's alpha was satisfactory in all of the measurements (0.73 and 0.80 respectively); the ICCs were good/excellent in all of the measurements (0.99 and 0.90, respectively). The results show that HERRS has the potential to examine the risks of the home environment adequately for the home structure of Turkish society in detail and is a valid and reliable test that health professionals can use.

Tıp Fakültesi Öğrencilerinin İngilizce Öğrenme Motivasyonları Ölçeğinin Geliştirilmesi

This study aims to develop a scale determining the extrinsic, integrative, and intrinsic factors that motivate medical students learning English as a foreign language in an ESP context. Derived from Gardner and Lambert’s socio-educational model (1972) and Deci and Ryan’s self-determination theory (1985), the study is based on the motivational framework of Noels et al. (2000) which categorizes the three main motives as intrinsic, instrumental and integrative. With the participation of 320 medical students, a 14-item scale was developed with satisfactory internal consistency. Four different methods were used to create the motivation scale. First, a focus group interview was conducted with the participation of randomly selected medical students, and 22 items were determined as a result of the content analysis and were sent to five medical doctors for their opinions, and 6 items were removed from the pool upon their feedback. Next, the literature was reviewed and comparisons were made between existing scales. Finally, based on the opinions of 3 English for Specific Purposes (ESP) experts from the field, the concept of extrinsic motivation was used instead of instrumental motivation, and a 16-item five-point Likert type scale was decided. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) statistical procedures were also utilized. Principal Components Factor Analysis (PCA) was applied to reveal the construct validity of the motivation scale, and Direct Oblimin with Kaiser Normalization method was applied as the rotation method. In order to calculate the adequacy of the sample, the Kaiser-Mayer-Olkin (KMO) coefficient was calculated. Finally, as a result of Bartlett sphericity tests to detect correlations between the items, it was determined that the norm values were provided for all statistical processes for the 3-factor structure explaining 64.62% of the total variance. Finally, this study presents a new data collection tool that is statistically valid and reliable to measure medical students’ motivational factors.

Cross-cultural adaptation and validation of the simplified Chinese version of the Exercise-Induced Leg Pain Questionnaire (EILP)

Purpose This study cross-culturally adapted and psychometrically validated a simplified Chinese version of the Exercise-Induced Leg Pain Questionnaire (SC-EILP) for evaluating the severity of symptoms and sports ability among individuals with exercise-induced leg pain. Materials and methods One hundred and fourteen participants with exercise-induced leg pain were included. To assess reliability, we calculated Cronbach’s α and intra-class correlation coefficient (ICC). Construct validity was analysed by assessing the correlations between SC-EILP and visual analogue scale (VAS), University of California Los Angeles activity score (UCLA), and short form (36) health survey (SF-36). Factorial validity was used to establish the factor structure of the questionnaire. Results The EILP was cross-culturally well-adapted and translated into simplified Chinese. Each item was appropriately correlated with the total items. SC-EILP had nearly good reliability [Cronbach’s α = 0.798, ICC = 0.897, 95% confidence interval 0.851–0.929]. The elimination of any one item in all did not result in a value of Cronbach’s α of <0.80. SC-EILP had a very good correlation with VAS (−0.607, p < 0.01) and a moderate correlation with UCLA (0.581, p < 0.01) and physical domains of SF-36 (0.499–0.528, p < 0.01). Exploratory factor analysis revealed the 3-factor loading explained 74.736% of the total variance [Kaiser–Mayer–Olkin (KMO) = 0.672, C 2 = 665.34, p < 0.001].

Stock Procurement and Documentation as Emergency Trolley Content Discrepancy Factors in Emergency Installation (Study on a Private General Hospital in Malang Regency)

One of the common problems in managing emergency logistics is the emergency trolley that conflicts with the standard operating procedures. It causes a mismatch of the emergency trolley contents. In fact, the availability of unstandardized emergency trolleys will impact the quality of emergency services in the emergency department. The emergency medicine shortage and emergency trolley content discrepancy also occurred several times in the ER. This study was conducted to analyze the determinant factor of content discrepancy in the emergency trolley in the emergency room of a private hospital in Malang Regency. The research method used was descriptive quantitative. The methods of identifying the root of the problem were carried out through field observations, literature studies, brainstorming, and Focus Group Discussions (FGD). Statistical tests were done using Bartlett's test of sphericity and Kaiser-Mayer Olkin (KMO) with a value higher or equivalent to 0.5. The study results formed two determinants of content discrepancies in the emergency trolley in the ER. The stock procurement factor is able to explain the problem by 48.02%, and the process documentation factor is able to explain the problem by 17.63%.

Factors Influencing the Performance of Indoor Environmental Quality of Pharmaceutical Factory Buildings in Southwest Nigeria

Pharmaceutical factory workers spend 37.5% of their daily time in the production hall manufacturing drugs used for human health needs. There is usually little or no time given to spend in the natural environment. This affects their sanity and well-being. The Pharmaceutical factory building (PFB) is classified as a specialized, controlled, or restrictive building; it provides little or no access to natural environmental conditions like ventilation and lighting, thereby increasing the financial implication of energy for the operation of production of drugs. Hence, the survey was conducted to identify the factors that influence the indoor environmental performance (IEP) of PFBs. The factors responsible for influencing the indoor air quality were measured through a survey conducted in Lagos and Ogun States, Nigeria on 14 PFBs to determine the value of these factors identified, using principal component analysis (PCA), Bartlett Test, and Kaiser-Mayer Olkin (KMO): the conditions for PCA were also observed. PCA is a factors or data reduction technique to select a subset of highly predictive factors from the larger group of factors identified from the study. Indoor environmental quality variables satisfied the condition for PCA while thermal performance variables did not meet the condition. PCA was conducted for Indoor environmental quality and the result showed 2 major factors explaining the variation in the original set of variables. Whereby CO2, P.M1.0, P.M2.5, P.M10, HCHO, airflow, AQICN, and AQIUS as component 1 and TVOC as component 2, the data set was also compared with the standards recommended for indoor environmental quality and thermal performance variables. It was found that at an average air velocity of 29°C and RH of 60%, the average CO, TVOC, PM2.5, and PM10 were 0.25ppm, 0.31ppm, 33.92ppm, and 43.48ppm respectively for the PFBs. Because thermal performance includes several dependent variables, greater research on the indoor environment of PFBs in Nigeria is recommended to determine the impact of indoor environmental characteristics on thermal parameters.

Association Of Eating Patterns With Screen &amp; SleepingTime In 10 Year-Old Schoolchildren

Purpose: To measure the association of dietary patterns with screen and sleeping time in 10 year-old schoolchildren. Methods: The sample was comprised of 278 boys (10.1 ± 0.5 y-old) with body fat percentage of 21.2 ± 9.5% and 289 girls (10.1 ± 0.3 y-old) with body fat percentage of 24.8 ± 8.4% from São Caetano do Sul, Brazil who participated the ISCOLE project. Dietary patterns and screen time (TV, computer and video games) were assessed using a diet and lifestyle questionnaire, and sleep time was determined by accelerometry (24 hours for 7 days; ActiGraph GT3X-+). For the dietary pattern, the Kaiser-Mayer-Olkin (KMO) was estimated and the Bartletts spherical test was applied to indicate the adequacy of the data for the analysis, followed by exploratory factor analysis, with extraction of 2 factors (“unhealthy” and “healthy”). To examine the association of dietary patterns with screen time and sleep time, Spearman correlation was used. Results: Screen time during the week and on the weekend showed a significant, weak, and positive correlation with the unhealthy eating pattern. Conclusion: There was an association of screen time and unhealthy eating pattern, showing that the longer the screen time during the week and weekend, the higher the unhealthy eating pattern score.*p.0.05

Identifying Key Selection Criteria for Smart Building Technologies in the United Arab Emirates Prisons

The selection of an appropriate smart building technology has been a challenge for stakeholders, because no specific selection criteria are currently available. This study aimed to identify the potential selection criteria for the selection of smart building technologies for prison buildings in the United Arab Emirates. A questionnaire survey was conducted to evaluate the relative importance of smart building technologies and the specific selection criteria. 238 experts from the public and the private sector with rich experience in the construction and prison industry participated in the survey. The data obtained were analyzed for descriptive statistics and the Mann-Whitney U test was conducted to compare the responses of the government and private sector respondents. Cronbach’s coefficient was estimated using reliability analysis. Finally, exploratory factor analysis was performed by Principal Axis Factoring (PAF) to extract the contributing factors and was further improved by varimax rotation using SPSS. To evaluate the appropriateness of the factor extraction, the Kaiser-Mayer-Olkin (KMO) measure of sampling accuracy and Barlett’s test of sphericity were conducted. The results demonstrated that most participants thought that the safety and security, anti-hacking capability, high working efficiency, and durability of the new smart building technology were very important. 14 listed selection criteria were extracted into three factors by factor analysis explaining 50.585% total variation. Regarding smart building technologies, fire protection was mostly voted by the participants followed by video surveillance and heat, ventilation, and air-conditioning system (HVAC). This study is a novel research study identifying the key selection criteria for the selection of important smart building technologies and would be helpful for a broad audience.
