The present research aimed to identify and analyze the factors influencing water conservation behaviors (WCBs) and determine the most important ones. The research adopted a causal-relational method with a questionnaire compiled for data collection. The validity and reliability of the questionnaire based on the calculation of Cronbach’s alpha for different sections were between 0.71 and 0.95. The statistical population included 5473 wheat farmers in Bukan Township, Iran. Krejcie and Morgan tables were used to calculate the sample size of 357 people. All these farmers have key information about the effects of climate change (e.g., drought) and are pioneers in using adaptation and water conservation strategies in wheat production. In this study, the sample size was determined using stratified sampling method with proportional assignment. The questionnaire validity was approved by the validity expert board. According to the findings of the exploratory factor analysis, the most important factors influencing WCBs of wheat producers included “institutional”, “economic”, “natural”, “extensional”, “social”, “attitudinal”, and “self-identity” ones. These seven factors together accounted for 47.498% of the variance in WCBs of wheat producers. The relationship between independent variables and wheat growers’ WCBs was determined by Pearson correlation coefficients. According to the results, economic, institutional, natural, attitudinal, social, and self-identity factors had a significant relationship with WBC at 1% error level. The regression results also showed that among the studied variables, economic and extensional factors had the greatest impact on wheat growers’ WCBs. The results can help managers and planners determine policies that focus more on economic and extensional factors that have been neglected in previous studies.

The topic of metamemory had attracted the attention of many researchers and scholars in the field of educational and cognitive psychology, especially how individuals become aware of and control their memory functions. Therefore, the aim of the present study was to build a psychometric scale/questionnaire for measuring metamemory. The study was conducted among a sample of 200 students joining Sharia/Islamic Law, Arabic Language, Education, English Language, Science, Economics and Management at Al Qassim University. For the purpose of the content validity of the scale, it was verified by the raters’ agreement and the internal consistency of the items of the scale. Pearson correlation coefficient was also used to calculate correlation coefficients between the scores of each item and its dimension to ensure consistency and homogeneity of the items and dimensions of the scale. The correlation coefficients of the items of the scale and the total score of the dimension to which the items belong were all positive correlation coefficients and statistically significant at the level of 0.01, which confirms the consistency and homogeneity of the items of each dimension. The homogeneity of the dimensions of the scale was also verified by calculating Pearson correlation coefficients between the score of each dimension and the overall score of the scale. The reliability of the scale and its sub- dimensions was verified using the α- Cronbach Alpha coefficient. The results showed that the scale and its sub- dimensions had high and statistically acceptable validity and reliability coefficients. Such result indicates that the scale is statistically valid and reliable.

Objective: To investigate the validity and reliability of a Chinese version of Spinal Cord Independence Measure III (SCIM III) in individuals with spinal cord injury. Design: Study on psychometric properties. Setting: An inpatient rehabilitation facility in China. Subjects: 102 participants with spinal cord injury. Mean (SD) age was 48.8 (15.6) years; tetraplegia/paraplegia ratio was 50/52; median time post injury was 2 months. Intervention: SCIM III was translated into Chinese. Chinese versions of Barthel Index and SCIM III were filled out for each participant by Rater 1. SCIM III was then administered by Rater 2 after 24 hours ( n = 67) and 7 days ( n = 65). Main Measures: Validity, inter-rater/test-retest reliability, and internal consistency of the Chinese version of SCIM III. Results: The total scores between the two raters were similar (mean ± SD: 33.8 ± 25.8 vs 33.8 ± 25.5, P = 0.95). Total agreement between the raters in each item was >80%, with both Pearson and intraclass correlation coefficients >0.97 ( P < 0.01) for each subscale and total score. The Pearson correlation coefficients of the two independent assessments performed by Rater 2 were also >0.97 ( P < 0.01) for each subscale and the total score. Cronbach α was >0.7 for each subscale and the total score for both raters. High consistency was found between Barthel Index and SCIM III total scores (Pearson correlation coefficient = 0.88, P < 0.01). Conclusion: The Chinese version of SCIM III is valid and reliable for the functional assessment of patients with SCI.

Purpose Identifying and prioritizing the risks are considered as critical issues in risk management; otherwise, non-considering the risks will lead to the problems such as delays in project implementation, increased costs, loss of reputation, loss of clients, reduced revenue and liquidity and even bankruptcy. The paper aims to discuss these issues. Design/methodology/approach In this paper, the factors influencing the organization risk tolerance level were identified. Then, the factors increasing and decreasing the risk tolerance level were determined by a decision-making model. Finally, a comprehensive model was considered for risk measuring and preparing a risk failure structure chart, in order to determine the factors influencing it as well as the measurement criteria and then they were ranked using the taxonomy method. In this study, the size of the statistical population was 130 (six small and medium manufacturer and service provider companies). Based on Cochran’s sample size formula, 97 questionnaires containing 30 questions were randomly distributed among the population. Validity and reliability of the questionnaire were confirmed. The data were analyzed by SPSS 22. Findings Given the hypotheses of this study, the first hypothesis was rejected and the other hypotheses were accepted. The final ranking was done using the taxonomy method; the personality of the project manager was ranked at first; income, credit and capital were ranked second and the number of personnel was ranked third. Moreover, the TOPSIS method was used for ranking to compare the results. Originality/value In this research, the identification and ranking of these factors have taken place in several small- and medium-sized organizations; in addition, the rankings are conducted using the taxonomy decision-making method.

Abstract Background The purpose of this study was to investigate the relationships among cardiac rehabilitation knowledge, educational need and health behavior practice in patients with coronary artery disease and explain factors influencing health behavior practice. Method The research participants were 189 patients with coronary artery disease from general hospital located in Korea. Self-evaluation questionnaires were used to collect the data. Data was collected from January to May, 2020. Data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Pearson correlation coefficients and multiple regression with the SPSS 24.0 program. Results There were significant positive relationships between cardiac rehabilitation knowledge and health behavior practice (r = .37, p < .001), and significant positive relationships between educational need and health behavior practice (r = .17, p = .022). Factors influencing health behavior practice were identified, the most critical predictive factor was age (≥80) (β = .52), followed by cardiac rehabilitation knowledge (β = .42), regular exercise (No) (β = −.25), family history (No) (β = .24), age (60-69) (β = .22), cohabitation (No) (β = −.20) and educational needs (β = .17). The explanation power of this model was 50% and it was statistically significant (F = 13.42, p < .001). Conclusion This study suggests that cardiac rehabilitation knowledge and educational need should be considered in enhancing cardiac rehabilitation programs designed for patients with coronary artery disease.

Diet History Questionnaire

This study aimed at developing a valid culture-sensitive quantitative food frequency questionnaire (FFQ) for Qatari adults. A convenient sample of healthy Qataris (n = 107) were recruited from family members of Qatar University students. The Diet History Questionnaire II of the US National Cancer Institute was translated to Arabic language, back-translated to English, pilot tested, and then modified accordingly to be used in Qatari setting. Participants were asked to complete the translated version of the FFQ. This FFQ was then validated against three 24 h diet recall (24 hDR) including a weekend day. Participants were asked to complete the FFQ again after one-month period to measure its repeatability. Dietary data were analyzed using the dietary analysis software ESHA. The validity and reliability of FFQ were assessed by comparing the median intake of nutrients and foods and by calculating the Pearson correlation coefficients. The median nutrient intakes assessed by the second FFQ were higher than that reported in the baseline FFQ1 except for fat. The percentage of increase varies between 1.5% and 96%. Results of the second FFQ indicated an overestimation of intake for most nutrients (macro and micro). Macronutrient intakes assessed by the two FFQ and 24 hDR were strongly correlated. The correlation coefficients for micronutrient intakes between FFQ2 and 24hDR were lower than that of the two FFQs except for calcium (r = 0.55) and sodium (r = 0.643). They ranged from (−0.17) for fluorine to (0.643) for sodium. The agreement rates for classifying macronutrient intakes into same or adjacent quartile were between 79.4% and 100% for the two FFQs and between 71% and 100% for the second FFQ and 24hDR. The reported consumption of food groups estimated by FFQ2 was significantly higher than that reported by FFQ1. In conclusion, the developed FFQ was sufficiently valid to assess energy and macronutrients but not micronutrients. The reliability was adequate for most nutrients.

Access to raw data of graphs presented in original articles to calculate effect size in meta-analysis studies of single-case research is one of the challenges that researchers encounter. Researchers typically use data extraction software programs to extract raw data from the graphs in articles. In this study, we aimed to analyze the validity and reliability of the use of PlotDigitizer software program, which is a widely used in literature and alternative to other data extraction programs, on computers with different operating systems. To accomplish this task, we performed the digitization of a total of 6.846 data points on three different computers using 15 hypothetical graphs with 20 data series and 186 graphs with 242 data series from 29 published articles. In addition, using the values we digitized we recalculated the 23 effect sizes presented in the original articles for validity analysis. Based on our sampling, we calculated inter-coder and intra-coder Pearson correlation coefficients. The results showed that PlotDigitizer could be an alternative to other programs as it is free and can run on many current and outdated systems, and it is valid and reliable as it is nearly perfect. Based on the obtained results and considering the data extraction process, various recommendations are presented for the researchers that will use PlotDigitizer program for the quantitative analysis of single-case graphs

AbstractObjectiveTo assess the validity and reliability of the most recent adaptation of Block's full-diet food-frequency questionnaire (FFQ) among a sample of Canadian women.DesignParticipants completed a self-administered FFQ (FFQ1), two unannounced 24-hour recalls (weekday and weekend) and a second FFQ (FFQ2) between October 2003 and February 2004. FFQs and recalls were analysed for 32 nutrients using Block Dietary Data Systems and the University of Minnesota's Nutrient Data System. Mean and median intakes were computed, along with crude and deattenuated Pearson correlation coefficients between FFQ1 and the average of two recalls (validity) and between FFQ1 and FFQ2 (reliability).SettingOntario, Canada.SubjectsA random population-based sample (n = 166) of women aged 25 to 74 years.ResultsOne hundred and fifteen (69%) women completed FFQ1, 96 completed FFQ1 and both recalls, and 93 completed both FFQs, about 56 days apart. Mean intakes were similar for most nutrients. FFQ reliability was high, with Pearson correlation coefficients having a median of 0.75, ranging from 0.57 to 0.90 (macronutrients) and from 0.65 to 0.88 (micronutrients from supplements and food). FFQ validity was moderate to high, with deattenuated Pearson correlation coefficients having a median of 0.59, ranging from 0.11 to 0.73 (macronutrients) and from 0.50 to 0.76 (micronutrients from supplements and food). Our micronutrient correlations were similar to or higher than those of other studies that included supplements. Two correlations <0.40 were associated with fats.ConclusionsThe validity and reliability of this full-diet version of the Block FFQ were moderate to high, supporting its use in future studies among Canadian women.
