Background & objectives: Content validity is the first type of validity that has to be ensured during the design of a tool. Its prerequisite for other validities and its close relationship with the tool reliability place it in a vital position in the questionnaire design. However, since it has not been paid enough attention in national publications therefore in this paper we will explain the different steps in preparing an appropriate content for questionnaires and also their assessment.
Methods: The steps of the content validation process for designing valid and reliable questionnaires have been explained in this paper: development (domain identification, items generation and instrument construction), Judgment – quantification (determining the inter rater agreement among experts, determining the clarity and relevancy of each of the questions along with the clarity, relevancy and comprehensiveness of the tool as a whole) have been explained.
Conclusions: The benefits of performing the content validation in questionnaire development are not increasing the possibility of accessing desirable content validity indexes (relevancy, clarity, and comprehensiveness) only, but also improving the Reliability indexes of tool and decreasing need for resources (financial and temporal) are the other benefits of this approach. Although subjective nature of experts’ responses is the problematic issue in this process but the more quantitative steps of the content validation has reduced considerable part of previous worries about this process. These issues explain why content validation has become a suitable process for questionnaire

Background & Objectives: To be able to measure the extent of job stress, it is essential to use a standardized tool based on a standard theoretical model. The study aims to test the psychometric properties and criterion validity of the Farsi version of the Effort Reward Imbalance (F-ERI) questionnaire.
Methods: The Farsi version of the ERI Questionnaire was distributed to 227 male employees in Isfahan Polyacryle Company. Internal consistency, reliability, discriminative validity, and factorial structure were evaluated. The relationship between scales and depression was measured assessed by using logistic regression to criterion validity. Data were analysed by SPSS 18 and LIZREL 8.5.
Results: Mean score of effort, reward, and overcommitment were 10.7, 41.4, and 14.2 respectively Cronbach’s alpha coefficients were 0.61, 0.85 and 0.67 and split-half coefficients were 0.53, 0.85, and 0.65. All of item-total correlations were more than 0.20 correlation between each item and its scale were more than 0.4 except for one item. Effort and overcommitement had a good fit for construct validity.
 Conclusion: Current study results indicated the Farsiversion of the Effort Reward Imbalance (F-ERI) questionnaire is a reliable and valid tool to measure psychosocial stress at work among Farsi-speaking employees. It is advisable to evaluate the tool in longitudinal studies and other industries which included female employees. We refer the investigators to see the longitudinal results of current project which is under publication.

Background and Objectives: This study assessed the validity and reliability of the Persian version of the standard "Problematic Internet Use" questionnaire to be used in epidemiological studies.
Methods: This cross-sectional study was performed in 2016. This questionnaire comprises five domains, including preference for online social interaction, mood regulation, cognitive preoccupation, compulsive Internet use, and negative outcomes. The questionnaire has 15 questions with a total score ranges from 15 to 105. A score of 15-45 indicates a normal state, a score of 46-65 shows a mild disorder, a score of 66-85 suggests a moderate disorder, and a score of 86-105 reveals a severe disorder.
Results: Three hundred and seven students (31.1%) had a normal score, 445 (45.1%) had a mild disorder, 191 (19.4%) had a moderate disorder, and 43 (4.4%) had a severe disorder. Based on CVR, 10 questions had a validity of 100%, 3 questions had a validity of 80%, 1 question had a validity of 40%, and 1 question had a validity of zero. The overall validity of the questionnaire was 85.3%. Based on alpha coefficient, the reliability of the domain of preference for online social interaction, mood regulation, cognitive preoccupation, compulsive Internet use, and negative outcomes was 87.6%, 91.1%, 89.8%, 90.8%, and 86.2%, respectively. The overall reliability of the questionnaire was 92.5%.
Conclusion: The validity and reliability of the questionnaire were high; thus, it can be used as a standard tool in epidemiological studies to explore the pathology of injuries related to the Internet and social networks.

Background and Objectives: Accidents are one of the global concerns in public health. About 1.24 million people die in traffic accidents annually. Road accidents are the leading cause of years of life lost in Iran and motorcyclists are the riskiest group of road users. Drug abuse is one of the main causes of road traffic accidents and motorcycling is more popular in drug abusers. So, this study was conducted to compare the riding behavior of normal and drug abuser motorcyclists.
 
Methods: This historical cohort was performed in 411 motorcyclists in 3 study groups: 100 methadone consumer motorcyclists, 100 methamphetamine consumer motorcyclists, and 211 normal motorcyclists. The participants in three groups were matched for age and area of residence. A motorcycle riding behavior questionnaire was used to collect the data. Then, the collected data were analyzed with the SPSS (V-20) software using descriptive and analytic statistics. Multivariate linear regression was applied for statistical analysis.
 
Results: There was a significant difference in the riding behavior score between normal motorcyclists and methamphetamine user and methadone user motorcyclists (P<0.0001), but the difference between drug user motorcyclists was not significant (P=0.292). The most frequent violation in all three groups was speeding.
 
Conclusion: the results showed speeding was the most frequent violation in all three groups followed by traffic errors. It was found that drug abuse (methamphetamine and methadone) could have an impact on motorcyclists’ riding behaviors as it could increase the riding behavior score in drug user motorcyclists compared to normal motorcyclists.

Background and Objectives: Satisfaction is a valuable measure of the quality of care and the patient-provider relationship. The Dental Satisfaction Questionnaire is a valid and international instrument for evaluating dental satisfaction. The aim of this study was to assess the validity and reliability of the Persian version of the Dental Satisfaction Questionnaire.
 
Methods: Upon assuring the precision of Persian translation, assessment of face and content validity was performed using the opinion of 10 patients and 10 experts. The validated questionnaire was then distributed among 300 patients attending the dental clinics using multistage cluster sampling. Factor analysis was used to assess the structure validity of the questionnaire and to elicit the factors predicting total satisfaction. Cronbach’s alpha was used for assessing the reliability of the questionnaire. 
 
Results: After some changes in some questions, the face and content validity of the questionnaire were confirmed. Factor analysis revealed 7 domains could determine 61.3% of total variance, including clinical quality, service quality, availability of care, pain management, cost, access, and empathy and responsiveness of dentists. Correlation of each domain with the total satisfaction was above 0.4. The mean satisfaction was 60.6 ±9.1. Cronbach’s alpha was 0.74.
 
Conclusion: The Persian version of the DSQ is a valid, reliable, and appropriate instrument for evaluation of dental satisfaction of Iranian population. The elicited domains could properly determine the total satisfaction.
