There are various questionnaires in the world to assess the level of knowledge and attitudes of people about Alzheimer’s disease. Dementia Knowledge Assessment Scale (DKAS) and Dementia Attitude Scale (DAS) questionnaires are two well-known questionnaires in this field, respectively. The purpose of this study is translation and psychometrics evaluation of two questionnaires DKAS and DASS and appropriating it with the culture of Iranian society.

Initially, the questionnaires were translated. The content validity of the questionnaires was assessed by 10 experts. To measure content validity, inter-rater agreement (IRA), relevancy and clarity of each of the items and the tool as a whole and comprehensiveness were calculated.  Reliability was measured with Cronbach’s alpha and intra -cluster correlation.

The Inter Rater Agreement to relevancy and clarity of the tool was 94% and 76%, respectively. The overall relevancy and clarity of the tool calculated through the mean, was 99.2% and 96%, respectively. Eventually its comprehensiveness was 100%. Overall Cronbach’s alpha in knowledge and attitude scale was 0.71 and 0.76, respectively. The highest ICC value was 0.97 and the lowest was 0.81 in the knowledge tool and 0.97 in the attitude tool in both areas.

The results of this study show that the tools used to measure the level of knowledge and attitudes of health care providers about Alzheimer’s disease have good content validity and reliability.

global rating system system is applicable, faster in time and easily handled.Butthe student may receive different scores by different assessors and it possibly led to different scores if repeated. This study is done to design and compare psychometric properties of the checklist for clinical skills assessment of dental students in removable partial denture course and evaluate the rater’s and student’s satisfaction about it. Materials &

 The checklist was analyzed by expert panel while the view points of the scientific member of staff was analyzed and applied in the designed checklist.The content validity of the checklist was measured by lawshe.Then, reliability of the checklist itself and reliability of the assessros was determined by test re test.The satisfaction rate of the scientific member of staff and the students about the checklist was also measured using a 5-scaled instruments.

 The satisfaction rate of the students and scientific member of staff was also high about the designed checklist; however, member of staff showed higher satisfaction than the students.The staff showed the highst satisfaction on the item (To what degree, the checklist is successful not to be affected of the staff’s personal views in scoring?) with the mean score of 4.6 while they gave the least satisfaction on the item (To what degree, the checklist is applicable to the assessors?) With the mean score of 3.0.

Conclusion Due to the validity and reliability of the checklist and the satisfaction of students and professors, it seems that the designed checklist can be used to evaluate students in this course.

The HIV/AIDS is spreading rapidly in the middle east and Iran. The health belief model is one of an appropriate model to assess the preventive behaviors. In this way, this study was conducted to design and evaluate the validity and reliability of a cultural-based psychometric instrument of AIDS in teachers and parents of Iranian students. A scale including 58 items relevant to preventive behaviors in AIDS/HIV was developed by reviewing literature.  Then, content and construct validity were evaluated using qualitative and quantitative methods, through the involvement of the participants and expert panel. The internal consistency was evaluated and approved using Cranach's alpha index, and test-retest analysis. The face and content validity of the primary developed scale was confirmed by item impacts of 1.5, CVR 0.49 and CVI 0.79, and the number of items decreased to 46. Considerably, the exploratory factor analysis approved the construct validity by factor loading of more than 0.40 in six factors (perceived susceptibility, perceived severity, perceived benefit, perceived barrier and perceived self-efficacy), including 35 items that jointly accounted for 59.49 % until 67.20% of the observed variance. The internal validity of the scale was approved by Cronbach’s alpha coefficient for the subscales ranged from .80 to .86 for each group, and the intra-class correlation coefficient ranged from 86 to .96. The results presented that the developed scale underpinning of the constructs of HBM in preventive behaviors of HIV/AIDs among students, teachers and parents had an appropriate validity; and an acceptable reliabliability.

Development and assessment of measurement tools are important stages in the research processes regarding social, educational, and medical sciences, which mainly focus on the measurement of characteristics, qualitative variables, and abstract variables. Validity and reliability are two important components of researcher-made tools. The quality of assessment and confirming of validity and reliability are major concerns in research. Before publishing their findings, researchers are required to provide a report on the quality assessment of the validity and reliability of measurement tools. Precision in explaining these features could lay the ground for commenting on the trustworthiness and validation of the obtained findings, as well as their comparison with previous studies. If the validity and reliability of research instruments are not confirmed, the endeavors of researchers might be degraded. The present study aimed to elaborate on the significance of validity and reliability indices in medical research and the qualitative and quantitative assessment of content validity on confirming the reliability of measurement tools.

Knowledge management is the process of using knowledge to achieve intended purposes. Since there are extremely high health, safety and environmental risks in healthcare system, knowledge management not only helps the patient health, but also improves the health and safety of healthcare workers through using proper information and experiences.
In this study, a questionnaire with 11 key questions was developed, Then for the evaluation of validity and consistency of the primarily questionnaire, Inter Rate Agreement and Cronbach α coefficient were used. Finally based on information collected, data was done by the binominal test with SPSS-22 software.
The relevancy (92.7%) and clarity (91.8%) were found to be acceptable, the questionnaire was internally consistent (α=0.7) and the results of binominal test showed that all questions were accepted (up to 75% for each) by the experts.
Although knowledge management is a new area in our country, it is important applying new and beneficial patterns in various aspects of activities like HSE management. Based on obtained results, in can be concluded that the introduced questionnaire is a valid and reliable tool for using in workplace processes.

For the evaluation of the health status different questionnaires were used. The World Health Survey (WHS) Individual questionnaire has been applied in different countries as a short and standard tool. This questionnaire measures the health status of the individual in 9 domains. The objective of the current study was to validate the WHSIndividual questionnaire in Farsi.
In this validation study,forward-backward translation procedure was applied to the questionnaire. The validity of the questionnaire was assessed by 10 content and methodology experts and somepotential participants.Inter Rater Agreement (IRA), relevancy and clarity foreach item as well as comprehensiveness of the questionnairewere calculated.Reliability was measured usingCronbach`s alpha and Intra Class Correlation coefficient (ICC) through test-re-test in 20 convenient samples. To assess the discriminant validity, meanscoreswere compared between people with different self-rated health (SRH) status (good SRH=1743people and bad SRH=183).The means scores of the current questionnaire were also compared in two groups regarding the objective health (healthy=991, unhealthy=923).
Findings: Total clarity, relevancy and comprehensiveness of the questionnairewere 91%, 94% and 90%, respectively. ICC ranged between 0.68 and 1 with the median of 0.89. Chronbach`s Alpha was 0.76. The average scores in groups with good and bad self ­­-rated health were 14.3±13.2 and 41.9±17.9, respectively (p This study has provided some preliminary evidence on the reliability and validity of the Iranian version of the World Health Survey Individual Questionnaire.

Accident investigation show that more than 90 percent of accidents cause by human errors. Human errors are also due to cognitive failures. Cognitive failures can be defined as cognitive-based errors on simple tasks that a person is normally able to complete without fault; such mistakes include problems with memory, attention or action. The present study was designed to develop a measurement tool for the estimation of cognitive failures in industrial workplaces. In the present analytical-descriptive study, an Occupational Cognitive Failure Questionnaire (OCFQ) was developed. For the evaluation of validity, internal consistency and repeatability of the OCFQ the content validity, Cronbach α coefficient and test-retest methods were used, respectively. A draft of 35-items questionnaire was created and following the evaluation of validity, five items were rejected. The new measuring instrument with 30-items was developed. The CVI for the final OCFQ was found to be acceptable (CVI=0.7). Results showed that the final OCFQ was internally consistent (α=0.96) and repeatable (ICC =0.996 and P<0.001). For measurement of cognitive failure in industrial workplaces, a valid and reliable instrument is required. Based on the obtained results, it can be concluded that the developed questionnaire (OCFQ) is a valid and reliable tool for the estimation of cognitive failures in industrial workplaces.

It is crucial to assess communication skills among health workers using valid culture-based instruments. This study aimed to develop and assess psychometric properties of the Interpersonal Communication Skills Scale among Zanjan Health Volunteers. Methods & Materials: In this study, a total of 191 health volunteers participated in a self-rating assessment of the Communication Skills Scale (CSS). Moreover, 14 experts were asked to rate each item based on the relevance, clarity, and simplicity. Through a literature review, we developed an instrument with 43 items. The validity of the instrument was determined using the impact item method, content validity ratio (CVR), content validity index (CVI), face validity and exploratory factor analysis. Reliability of the instrument was reported by Alpha Cronbach coefficient. The CSS finally contained 35 items, divided into two categories: general and specific communication skills. Of 43 items, those with impact item index over 1.5, CVR over 0.51, and CVI over 0.79 were considered as valid; while the rest were discarded resulting in a 35-item scale. Factor analysis was carried out to determine the relationship among the items of the CSS. Exploratory factor analysis reduced the list of items to 30, which were divided into seven groups with a minimum eigenvalue of 1 for each factor, capable of predicting 68.8% of the variance. Internal reliability of the scale was determined by alpha Cronbach coefficient (0.91). The results of this study indicated that the CSS is a valid and reliable instrument for assessment of the communication skills among health volunteers in Zanjan. These findings could be used for developing similar instruments in other health worker groups.
