Objective Work-related Musculoskeletal Disorders (MSDs) happen due to risk factors during work, across the world, especially in developing countries. Multiple risk factors (physical, psychosocial and mental) have contributed in MSDs as with most chronic diseases. Several tools are used to evaluate these risk factors. Quick Exposure Check (QEC) is one of the most accurate and quick-response tools for identifying these risk factors. The purpose of the present study is to translate cultural adaptation and to verify the reliability of the Persian-language rapid assessment evaluation checklist.
Materials & Methods This study is a methodological study. In this study, the intercultural equivalence of the QEC questionnaire was performed using the international quality of life assessment project. For doing face validity, the questionnaire was completed by 12 ergonomic experts and 15 employees. In this study, (ICC), (SEM), (α Cronbach) The checklist was reviewed on 80 construction workers. They were divided into two groups of 30 and 50. The questionnaire was completed at intervals of 3-7 days in two rounds.
Results The Persian version of QEC questionnaire was reported with easy terminology, wordage, and phrases. Interpreters were also unanimous about this, and the quality of translation was clearly translatable , the use of common language, conceptual equivalence, and the overall quality of translation was desirable. And the interpreter's agreement was satisfactory. In other words, the results of the formal validity check showed that all items were approved. High levels of internal consistency (α=0.74), inter-rater reliability (r=0.79-0.93) and intra-rater reliability (r=0.74-0.89) were obtained, too. Face validity had acceptable results from both workers and specialists’ perspective. In addition, SEM scale for inter-rater (4.9-0.4), intra-rater (2.8-0.73) showed low random errors.
Conclusion Questionnaire was verbally verified in a way that all 16 questions were clear, simple, and understandable with acceptable reliability. Therefore, The QEC can be applied as a specific risk assessment instrument for industrial and research studies in Persian language populations

The pandemic of HIV/AIDS is spreading rapidly in the Middle East, in particular in Iran. Designing an educational program involves assessment of the educational needs of people with valid and culture-based tools. This study was conducted with the aim of psychometric analysis of an instrument for assessment of HIV/AIDS knowledge based on the Iranian culture in different population groups.

In this psychometric analysis, 58 items related to AIDS knowledge were prepared based on a literature review. Then, the face validity and content validity of the instrument was determent by the impact item score, content validity ratio (CVR), and content validity index (CVI). The reliability of the scale was assessed by Cronbach’s alpha coefficient and test-retest.

Based on face validity and content validity, the research scale had 44 items with an item impact score > 1.5, a CVR > 0.49, and a CVI > 0.79. The Scale had three sections, general knowledge about HIV/AIDS (9 items), knowledge about HIV transmission (25 items), and knowledge about HIV/AIDS prevention (10 items). The Scale also had a high reliability (Cronbach’s alpha coefficient=0.77-0.91, ICC=0.88)

The results of the study showed the instrument was a valid and reliable scale for measurement of knowledge about HIV/AIDS.

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.

Background and Aimes: Children with spastic cerebral palsy have difficulties with balance and movement. Balance is a crucial factor of movement that facilitates functional skills. The purpose of the present study was to translate and to evaluate face and content validity of Pediatric Balance Scale (PBS).
In the current descriptive-analytical study, psychometric methods were assessed. Translation of this scale was accomplished in forward-backward process. Next, face validity was checked by 10 occupational therapists and content validity was evaluated by 10 other occupational therapists. Moreover, Content Validity Ratio (CVR) and Content Validity Index (CVI) were determined.
In translation process, one item was changed because it was confusing for occupational therapists. Face validity was obtained to be very high for this measure (2/87-4/70). Also, CVR (1- 0.73) and CVI (0.96) were in the acceptable range.
PBS has high face and content validity which is appropriate for assessing functional balance in children with spastic cerebral palsy.

Today, investigation of the health related to the quality of life of caregivers of the patients with chronic disease is among the mail objectives of trereatment teams, due to the key role they play in maintaining patients in the community. Given the wide range of spinal cord injury patients in need of assistance, usually by their relative or caregivers, to perform their daily and professional activities, the huge physical, psychological, emotional and economic burden may be reflected on the quality of life of their caregivers. The aim of the present study was to translate Caregiver Burden Scale into Persian and to study its content and face validity with the goal of creating a useful tool for evaluating and providing effective treatment strategies to reduce the burden of care and improvement of quality of life of caregivers and care recipients.
In order to be able to use the caregiver burden scale among Iranian caregivers, forward-backward translation procedure was followed to develop the Persian version of the scale. Face validity was evaluated by 14 caregivers and content validity by 14 specialists in rehabilitation.
Generally, the items were viewed to be acceptable from the viewpoint of caregivers and some items were suggested by the caregivers to undergo revisions. These items were discussed and revised in an expert panel. The results of the face validity in the view of caregivers indicate that the scale enjoys good validity in terms of relevance, clarity, and simplicity for all the items on a 4-point diagram. The results related to the necessity of CBS items in a three-point scale based on the opinions of 14 specialists in rehabilitation indicate a high content validity.
The results show that the Persian translation of "caregiver burden scale" is acceptable and it has acceptable content and face validity.

Musculoskeletal disorders are among the top 10 injuries accounting for absence from work. The Extended Nordic Musculoskeletal Questionnaire (NMQ-E) is one of the many tools used to examine these disorders. The present study was conducted to translate and localize the NMQ-E and to evaluate the face validity and test-retest reliability of its Persian version. The present non-empirical methodological study used the International Quality Of Life Assessment (IQOLA) approach to translate the NMQ-E into Persian. The face validity of the Persian version was examined in a sample of 15 patients with musculoskeletal disorders (MSDs) and its absolute and relative test-retest reliability were examined in a sample of 48 patients using the Standard Error of Measurement (SEM) and the Intra-class Correlation Coefficient (ICC). The Kappa coefficient was also used to measure the inter-rater agreement for nominal variables. The translation and localization of the NMQ-E was deemed easy and acceptable. All the items of the questionnaire had an acceptable face validity. The Intra-class Correlation Coefficient and the Standard Error of Measurement of the Persian version of the NMQ-E were deemed acceptable (SEM=0.56-1.76 and ICC>0.7) and the Kappa coefficient was calculated as 0.78-1.00. The Persian version of the Extended Nordic Musculoskeletal Questionnaire showed an acceptable validity and test-retest reliability for assessing musculoskeletal disorders in Iranian patients.

The aim of the current study was to translate and cross-culturally adapt the Swedish Occupational Fatigue Inventory (SOFI) into Persian and to evaluate its face and convergent validity.Method & Material: A methodological study was performed according to standard IQOLA protocols, including the following steps: translating the SOFI questionnaire, evaluating the quality of the translation, back-translation and comparison of the English version with the Persian version by the original developer. The translated version was completed by 200 nurses. The Persian version of the Modified Fatigue Impact Scale (MFIS) questionnaire was used to evaluate the convergent validity. Spearman’s correlation was used to evaluate the correlation between the items. On the whole, the translations of the sentences were easy. The quality of the translation including the ‘clarity of translation, common language use, conceptual equivalence, and overall translation quality’ of the items was good. Face validity of the questionnaire was acceptable and did not lead to multiple changes in the questionnaire. Spearman’s correlation coefficient showed a high correlation between the total SOFI score and total (Persian) MFIS score (r=0.71 and p<0.01). The Persian version of the SOFI has acceptable face and convergent validity and is ready for further evaluation of its reliability.

Recognizing the learning motivations among medical students is one of the major factors affecting the promotion of medical education. The aim of this study was to consider the motivational factors associated with learning in medical students of basic sciences upon the Keller’s motivational model. This cross-sectional study was done among 308 students of medical basic sciences studying at Tehran University of Medical Sciences in the second semester of 2011-2012. A researcher-made questionnaire was designed according to John Keller’s motivational model. The questionnaire had 20 questions in 4 axes of “attention”، “congruence”، “confidence” and “satisfaction”. Face validity، content validity and reliability of the questionnaire (0. 83) were confirmed. The collected data were analyzed by SPSS 16 software using Student T and Chi square tests. The students’ mean score for Keller’s motivational questionnaire was at the range 20 to 77. The mean total score of female students was significantly lower than that of the male students (p=0. 01). Motivational factors concerning “congruence” had more important role in promoting the female students’ motivation for learning than that of the male students (p=0. 01). The students’ score for the motivational questionnaire had no relation towards their age and their passed semesters، but a significant inverse relationship towards the students’ grade point average was observed. “To propose a question at the beginning of a lesson”، “using teaching aid tools”، “to talk about the future and spiritual and human aspects of medical sciences”، “clearer aims of a lesson and knowing the educational aims”، “to read favorite materials” and “being a challenging course” are of the most important motivational factors concerning learning among medical students.
