Abstract:This study was done to evaluate the validity and reliability of women’s reproductive
history questionnaire which will be used in Azar Cohort study; a cohort that is conducted by
Tabriz University of Medical Science in Shabestar county for identifying risk factors of no
communicable diseases. Content and face validity were evaluated by ten experts in the field
and quantified as content validity index (CVI) and content validity ratio (CVR). To assess
the reliability, using test-retest approach, kappa statistic w… Show more
“…where: N is the total number of experts and n is the number of experts who have selected the "necessary item" option. The minimum acceptable CVR value for a total of 10 experts is equal to 0.62 (Pezshki et al, 2017). Items with CVR values lower than this threshold should be eliminated from the test due to lack of suitable content validity.…”

All buildings require Repair and Maintenance (R&M) in their life cycle period. However, if R&M activities are not carried out properly, deterioration will occur, service life of buildings will be reduced, and maintenance costs will increase. Hence, selecting the appropriate R&M methods is pivotal, especially for developing countries, such as Iran, which are featured by highly constrained resources. The present study aims to identify and prioritize the main criteria for selecting the suitable R&M methods for Commercial Buildings (CBs), which is considered as a profound challenge for the Architecture, Engineering and Construction/Facility Management (AEC/FM) industry. A total of 20 senior experts in the AEC/FM industry and CBs in Iran were invited to participate in a Delphi survey to solicit their perceptions and opinions on the selection criteria. The total number of individual criteria identified is 16, which are further divided into five categories: human resources, flexibility and technical capability, risks, cost of maintenance, together with facilities and technology. Then, the Fuzzy Analytic Hierarchy Process (FAHP) technique was applied to prioritize the identified criteria. Among the 5 main selection criteria, the cost of maintenance is the most important criterion for selecting appropriate R&M methods for CBs whereas the criterion of human resources (HR) was recognized as the least important.

“…The content validity index and content validity ratio values of the questionnaire could not be assessed, as all the necessary criteria – relevancy, clarity, simplicity, and necessity were not assessed. [ 33 ] The practices could not be directly assessed due to practical difficulties experienced during the pilot study. In addition to this, the direct observation of the respondents when they start riding a two-wheeler may create a subjective bias or may indirectly encourage them to wear the helmet due to our observation (Hawthorne effect).…”
“…First, the pretest survey was conducted, with a response rate of 73.33% (42.86% academics and 100% consultants). After modifying the mailed questionnaire based on the feedback received through the pretest survey, the validity assessment was proceeded according to procedures documented by Ghahramani and Khalkhali (2015) as well as Pezeshki et al. (2017).…”

“…These findings indicate the effect of stress-based tension that can moderate the relationship between the effectiveness of safety training and the motivational problem of taking shortcuts via routine perception-based errors. The theorized moderating effect was employed to examine the strong influences of the relationship in the mediating effect, called as the moderated mediation effect (Pezeshki et al., 2017) and it can be represented as shown in Fig. 3.Fig.…”
An unsafe act is a type of work that involves some risk. Since more than a decade, unsafe act has accounted as a foremost cause of work-related accident, especially in the field of construction. Several attempts have been made to reduce the causes of unsafe acts; however, shortcut, which is a notable type of unsafe act, has received little attention in previous works, even though some of causal effects have been attributed to this habit. This paper aims to reveal an unexplained proportion that can be explained by different underlying causes of motivational problems to shortcuts rather than by habit. Accordingly, two structural models have been proposed based on quantitative and qualitative data from previous reviews associated with the effects on negative feeling and thinking on risk management. These models were tested using on Exploratory Factor analysis (EFA) and Confirmatory Factor Analysis (CFA) on data collected from a cross-section survey conducted at construction sites in largest cities within the Kingdom of Saudi Arabia (KSA), where large number of accidents in these cities occurred. Data of 204 respondents of the mailed questionnaires were analyzed after screening all responses. Statistical Package for Social Sciences (SPSS) (version 22) was used to test for Structural Equation Model (SEM) assumptions. The developed hypotheses were tested and model with the best fit was identified. Findings revealed that 45%–55% of the motivational problems to shortcuts were explained by the selected structural model.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
